Troubleshooting Eaton Gears Transmission & boshte
përleshje Gears
Snubbing and clashing gears while shifting are frequent abuses to which unsynchronized transmissions are subjected. Light snubbing will do little damage. The real damage is done by the hard clash shift caused by engaging gears which are far out of synchronization. This can break pieces of metal from the ends of the clutching teeth. Clashing gears can be traced to one of three causes:
Mërzitur Dhëmbët shtrëngon Gear
1. Zhvendosja pahijshme
This applies to drivers who are not familiar with the shift pattern or have not learned the RPM spread between shifts.
2. tufë
Clashing when starting up in first or reverse gear can be caused by insufficient clutch clearance or a dragging clutch not releasing properly. This makes the transmission countershafts and mainshaft gears continue rotating while the clutch pedal is depressed. Clashing results when the nonrotating sliding clutch is forced to mesh with a rotating mainshaft gear. Double clutching during lever shifts will also reduce snubbing and clashing.
3. inerciale Force
Countershafts dhe ingranazhet mainshaft zakonisht marrin nga 3 në 5 sekonda për të ndaluar rradhës pas tufë ka qenë i zënë. Përpjekje për të rrjetë një veshje tufë me një veshje mainshaft para gear mainshaft ndalesa do të rezultojë në përleshje. Nëse transmetimi nuk është e pajisur me një frenave tufë ose countershaft frenave, është e nevojshme të ndalemi pak sekonda pasi të dëshpëruar pedale tufë para se angazhimin fillestar të transmetimit.
Marks Prodhim
Sometimes gears are replaced or thought to be defective because of marks left on the gear by manufacturing processes. këto blemishes, megjithatë, do not contribute to gear failure and the gear should not be replaced because of these marks.
hob Marks
These are cutting marks or lines formed during the initial cutting of the gear teeth. Hob marks on the tooth face will be removed by the shaving process, but hob marks in the root of the tooth will most likely remain, and may be found even on gears with much wear on them.
Marks rroje
The shaving operation leaves distinct diagonal marks on the face of the gear tooth. These marks can be distinguished from scoring marks by the fact they are diagonal, while scoring marks are more nearly vertical. Most shaving marks are removed during normal gear operation.
Gear lipping
Lipping ose rroje papastërti, is the formation of “lips” at the tip of the gear teeth machining. Këto "buzët" do të bëjë asnjë të keqe në veshje.
Rattle Gear në boshe
Mainshaft gears are designed to have a specified amount of axial clearance which allows them to rotate freely on the mainshaft. The amount of clearance is governed by the use of washers. Një motor i përafërt përtaci mund të ngritur dridhjet, causing the mainshaft gears to rattle as they strike mating gears. This condition can usually be cured by improving the idling characteristics of the engine. Tolerance washers may have to be changed to bring the axial gear clearance to within tolerance on high mileage units. See the service manual for procedure and specifications.
Twist bosht dhe frakturë
Failure of transmission shafts through fracturing or twisting is caused when stresses are imposed on them which are greater than they were designed to withstand. The main causes for these failures are:
- Teknikat e pahijshme shtrëngon.
- Duke filluar në shumë e lartë e marsheve.
- zvarritje.
- Përpjekur për të filluar me frenat mbyllur.
- Transmission used for application it was not designed to withstand.
- Bumping në bankën e të akuzuarve kur mbështetjen.
- montimi i gabuar i timonit i rregullueshëm 5.
Ndarë Mainshaft
Si me dhëmbëve të dhëmbëzorëve, shafts may fracture as a result of fatigue or impact.
Twisted Mainshaft
Loads not severe enough to cause shaft fractures may cause the shaft to twist.
