Method of improving ZOOMLION excavator rzeppaconstantvelocity joint lubrication condition

Because the universal joint is one-time lubrication, so can not meet the excavator in harsh environments (such as wading operations, muddy road operation) the needs of work, often caused by poor lubrication of universal joint ball, ball, ball head and ball wear, so that scrap.

In order to improve the lubrication condition of the universal joint, an oil injection channel is injected on the cover of the universal joint. Specific method is:

A starter engine supports the front axle of the excavator so that the wheel is off the ground, and then turns the steering wheel to the left until the outer housing of the left universal joint is exposed. 2.

Drive the excavator in a straight line, and now drill through the phi 5mm through the center axis of the axle half of the cardan shaft and the front of the universal joint cover, and then tap the hole.

When lubricating grease is injected into the grease gun, the front wheel is rotated by a small force, and the grease is added into the universal joint with more grease.

After filling the grease, plug the hole with Phi 6mm 3 (the length of the screw block is the same as the thickness of the outer cover).

Put down the front axle and wheel the ground.

As the processing method of the joint right.

Practice has proved that when the cardan joint is added to the oil duct, grease can be injected in addition to the overhaul, and the lubrication effect is very good if it is injected again every quarter.
