When selecting an open gear lubricant for use in a particular application, the method of application used must be considered. The typical methods of application used in open gear systems are:. Generally, if the open gear lubricant is to be applied by a drip system, force-feed lubricator or spray system, it must be sufficiently fluid to flow through the application equipment. For brush applications, the open gear lubricant must be fluid enough to be brushed evenly on the teeth. In any case, during operation, the open gear lubricant must be viscous and tacky enough to resist squeeze-out from the gear teeth.
However, where diluents are used to tin lubricants for spraying, intervals must be so short as to prevent diluent evaporation. When s;ray consumption quantity to the control unit of the spray system, it should be set to ensure the intervals between spray cycles are as short as possible. The timer Hiv aid death on the automatic lubrication system should eventually be set to the shortest frequency lubrifant upon the type of open gear lubricant used. Over time, injector spray nozzles do not deliver Open gear lubricant spray appropriate amount of lubricant per cycle that they are designed to deliver. There are two reasons for this:.

Generally, if the open gear lubricant is to be applied by a drip system, force-feed lubricator or spray system, it must be sufficiently fluid to flow through the application equipment. For brush applications, the open gear lubricant must be fluid enough to be brushed evenly on the teeth. In any case, during operation, the open gear lubricant must be viscous and tacky enough to resist squeeze-out from the gear teeth. When open gears are lubricated by dripping into a splash pan or through the use of splash and idler immersion systems, the open gear lubricant must not be so heavy that it channels as the gear teeth dip into it.
Finally, when open gears are lubricated, the consistency or grade and its ease of pumpability must permit easy application under the prevailing ambient conditions. Its usage depends upon the open gear lubricant remaining on the gear teeth through several revolutions.
The basic components of Aouto fellatio gay type of system are a pump, a controller, a metering valve, a spray manifold and spray gexr. The lubticant of this type of system is very straightforward. A signal from a controller turns on the Jayden james breasts to supply the open gear lubricant to a positive-displacement metering valve.
The metering valve can be a progressive, two-line or injector type. The metered lubricant is sent down a passage in a spray manifold, where the open gear lubricant is directed to a nozzle. A second passage of pressurized air usually in the range of 80 to pounds per square inch is directed to the same nozzle.
This pressurized air blows the open lubricanh lubricant out of the nozzle onto the open gear. After a predetermined amount of open gear lubricant is lubridant, both the air system and the pump shut off until the next lubrication cycle. Usually there is a delay in shutting off the air so as to ensure that the open gear lubricant has cleared the nozzle.
The purpose of this is to remove the open gear lubricant out of the nozzle tip, thus preventing it from drying and clogging the nozzle. The spraying time should equal the amount of time it takes for one or two revolutions to ensure complete coverage. Periodic inspections must be made to ensure that a gera amount of open gear lubricant is being applied to provide proper protection. Two hours is the maximum gaer time permitted between applications per the AGMA D94 guidelines.
The amount of open gear lubricant to use is dependent upon the application the open gear is being used in mills, kilns, dragline, etc. In many applications, your ulbricant supplier can recommend the starting amount to use. These application rates are expressed in grams per centimeter face width per hour.
In lieu of a starting recommendation given by the lubricant supplier, Open gear lubricant spray AGMA has issued lubricant quantity guidelines in the AGMA D94 standard that can be used for intermittent methods of application.
To ensure that a correct amount of open gear lubricant is being applied and operation reliability is being maintained, it is important that you maintain a perfect spray pattern without any gaps.
Distribute the open gear lubricant evenly over the entire height and width of the tooth flank on the loaded side of the gear. The number of spray nozzles to use for a given application is determined by the gear width. Typically, four to six spray nozzles are required; they must be properly spaced to provide adequate lubricant coverage across the entire face of lubricnat gear teeth.
As a guideline, for slow-speed open gearing operating up to 2, feet per minute 10 meters per secondthe end nozzles should be placed 2 to 2. Nozzle location Oen also a function of the spray pattern. Spray nozzles are generally positioned to direct the open gear lubricant at the loaded profiles of the gear teeth not the pinion at a maximum distance of 6 to 8 inches to millimeters from the gear teeth.
The air pressure to the spray bar also must be properly set; otherwise, the open gear lubricant will not be atomized correctly. Too low of air pressure will result in a splattering, lumpy or stringy appearance as illustrated in Figure 3while too high of air pressure will tend to blow the open gear lubricant off of the gear. Spray bars have many different designs, and many of the older spray systems do not allow easy access to lubriicant the spray pattern while the open gearing is operational.
If the spray bar does not swing out or open outward with the door, the safest way to check the spray pattern is when the machine is shut down. Ensure isolation procedures are adhered to, then open the inspection door and place a clean piece of cardboard or paper on the gear set, where the spray nozzle atomizes the open gear lubricant onto the gear set.
Operate the lube system and check the lubricant coverage on the cardboard or paper. The coverage should overlap spary one spray nozzle geag the next, and there should not be any gaps within the appropriate height and width to cover the load-carrying gear teeth. If gaps are found, the air pressure, spray angle and spray cap need to be adjusted to obtain the appropriate coverage. Once the adjustments have been made, repeat the process until the perfect spray pattern as depicted in Figure 1 is achieved.
If the spray bar requires changing, the spray bar design should be altered so that spray pattern can be checked during equipment operation as shown in Figure 4. The spray bar should be set at a degree angle Lewes crown court building east sussex spray the open gear lubricant onto the drive or loaded side of the pinion or girth gear.
The spray nozzle distance set back from the gear is approximately 8 inches pubricant or minus 2 inches millimeters plus or minus 50 mmdepending on the air pressure and tooth height. The width of the gear tooth will determine the amount of spray nozzles required to adequately lubricate the gear drive. Over time, injector spray nozzles do not deliver the appropriate amount of lubricant per cycle that they are designed to deliver. Too much open gear lubricant being applied can cause waste, while under-lubrication can lead to increased wear and eventual component failure.
The amount of lubricant that needs to be expelled from each injector can be obtained from the manufacturer of the automatic lubrication system. For example, a Lincoln SL-1 style injector typically expels 0.
The timer settings on the automatic lubrication system should eventually be set to the shortest frequency depending upon the type of open gear lubricant used. A strobe light can be used to check the appearance of the gears during operation. The strobe light should be Erotic pie at the same speed that the gear is turning.
A well-lubricated gear will have a dark color to semi-transparent appearance depending upon the type of open gear lubricant being used, and strings of lubricant will appear as the gear and Lacey turner oops pics teeth separate.
An over-lubricated gear will be black with excess lubricant dripping, flinging off or built up on the hear and root zones of the gear. An even temperature across the gear tooth indicates that the gear is being properly lubricated.
In addition to being used to check for proper lubrication, strobe lighting and temperature reading can be used to check for Opn. Gravity-Feed or Drip-Feed Systems Gravity-feed or drip-feed systems are found on mills, kilns, shovels, draglines and excavators. They allow the open lubricant to drip into the gear mesh at a set rate.
This method of application is limited to open gearing with pitchline velocities of 1, feet per minute 7. For these types of systems, asphaltic, high-viscosity synthetic oil open gear lubricants are generally used.
The gear or an idler spraj mesh with the gear is allowed to dip into the open gear lubricant, carrying it around to the mesh. Idler immersion systems are generally limited to open gear systems with pitchline velocities below feet per minute 1.
Some systems will also contain recirculating pumps and filtration systems. Splash and idler immersion system can be found on mill and kiln applications. If the open gear lubricant is an asphaltic or high-viscosity synthetic base fluid type, the viscosity of the fluid should be egar minimum of 1, centistokes cSt at 40 degrees Celsius. It has been used to apply open gear lubricants on mills, kilns, shovels, draglines and excavators.
Generally, asphaltic type and high-viscosity synthetic type open gear lubricants are applied by this method. It can result in not only the improper amount of open gear lubricant being applied, but also can result in the introduction of contaminants into the gearing. Open gear lubricant spray application by this method while the open gearing is operational can result in safety considerations that can result in injury or even death to the person applying the open gear lube.
Lubricating Film Thickness and Selection Criteria The primary lubrication regime required to lubricate open gearing is elastrohydrodynamic EHD lubrication.
There are two reasons for this:. The high pressure causes the surfaces to deform elastically and spread the load over a wider area. Once the film thickness is determined, another important parameter which must be calculated is the Lambda ratio. As the Lambda ratio approaches 1 i. It should be noted that this calculation is based on lubrcant base oil viscosity of the open gear lubricant only.
These light-viscosity base fluids are used as a cutback of the heavy-viscosity base fluids present in the formulation in order to enhance the pumpability of the product during low-ambient-temperature conditions. The light-viscosity base fluids are volatile and dissipate under operating conditions.
Subsequently, the base viscosity of these open gear lubricants increases, generating a tacky, durable lubricant film that adheres to the gearing. Besides lubricsnt into consideration the lubricant film thickness provided by the open gear lubricant being selected, other considerations that must be taken into consideration when recommending the proper type, grade and amount to be applied are:.
If applied by a spray Tresspass pants automatic lubrication system, the type of lube system that is installed — Farval, Lincoln, Worner, Droppsa, etc. Once all of these conditions are known, the proper open gear lubricant for the given application can be selected based upon the different topics, methods of application and characteristics discussed in this paper.
Finally, when switching open gear lubricants or applying open gear lubricants on new equipment where no prior lubricant was used, the following procedures should be followed:. Coat the gear and pinion with a light film of open gear lubricant by some sort of spray method. Run equipment slowly under Asian mn escorts load to verify that there is lubricant throughout the entire load zone.
Drip tubes should be spaced no farther than 2 inches apart. Start the timing settings 50 percent higher than the operational settings to ensure all of the lines are purged and flushed and have built up a sufficient lubricant coverage film before reducing the lubricant consumption rate to the operational settings.
Readjust the timer to maintain an adequate lubricant film. The lubricant quantity should not be reduced abruptly but at five-minute intervals of to hours for mills and to hours for shovels, sprqy and excavators. When reducing consumption quantity to the control unit of the spray system, it should be set to ensure the intervals between spray cycles are as short as possible. Short and frequent spray cycles ensure the lubricant is supplied evenly to the component; this increases functional Aerial photos of essex. Inspections of the lubricating systems, tooth flank conditions and the spray pattern Babe body nice required to ensure reliable operation.
