Auto transmission shaft ten bytes to the requirements of the lubricating material except to have a good fight friction and wear resistance, still should have good mechanical stability, high temperature  (high drop point), anticorrosion, water resistance and oxidation stability and other characteristics.

Gear oil high temperature and water resistance is unable to meet the required. In addition to calcium in grease (hereinafter referred to as the calcium base fat), and lithium (hereinafter referred to as the lithium base fat), aluminum grease and sodium based on many kinds of grease. And in fact, automotive transmission lubrication is always use 2 or 3 lithium base fat, because the relative calcium and lithium fat have higher dropping points (lithium base fat for 170 ℃ 190 ℃, calcium base-fat for 90 ℃ 100 ℃) and good thermal stability.

Remove the technical requirements of the shaft is higher, generally need to car repair shop by professional repairman completed. And the axis of the drive shaft lubrication homework, belongs to the daily maintenance projects, general every travels 2000 km will maintain a, if every time the maintenance has to repair, this undoubtedly increase the economic burden of the owner; If each car is equipped with a special hydraulic filling equipment, also is not realistic. And with grease lubrication, just a common butter gun, the driver can complete, save time and the economy.

But some drivers operation method is not correct, can cause a grease can't enter the bearings inside. The correct operation method is: will butter gun out KouJin oil pressure in the butter the mouth, and constantly operating butter gun, make grease in pressure under the action of grease fitting into the shaft through internal oil way, and then reach the axis of the four shaft neck end, full of the needle bearing, and at the same time, to needle bearing grease of residual metamorphic within and impurities from oil seal place extrusion. For each bearing grease and impurity in the bad after all extrusion (see fresh out of the grease), the homework finished. Such as homework grease can't be pressure into the bearings inside, it should be replaced or remove grease fitting the shaft cleaning oil way, followed by charging, to ensure safety.

In addition, with the continuous development of auto industry, grease in the car industry widely used. The so-called grease, which is in the fat or composite lithium calcium base fat to add a small amount of colloid disulfide aluminum. For flake crystallization, its sulfur atoms to metal has a strong affinity, so it's easy in the friction surface of the oil film is only form.
