Pengpu bulldozer is a machine consisting of a tractor as the prime mover and an earth-moving machine with a cutting blade. It is used to remove land, road structures or similar work, and is an important machinery in engineering construction. It can accomplish projects that manpower cannot complete and improve work efficiency. It is a self-propelled construction machine with a bulldozing device and an operating mechanism mounted on the front of a crawler tractor. It is mainly used for digging road cuts, constructing road lifting, backfilling, removing obstacles and removing accumulated hail. It can also complete the operation of shoveling and piling of loose materials within a short distance. Pengpu is an early Chinese crawler bulldozer R & D and manufacturing enterprise. Now it has become a professional construction machinery manufacturer with complete varieties and wide applicability, whose R&D capability reaches the advanced level in China.
The proper maintenance method can make the life of Pengpu bulldozer longer.
Allow the pengpu bulldozer track to maintain proper tension
If the track tension is excessive, the tension of the guide wheel spring acts on the track pin and the pin sleeve, the outer circle of the pin and the inner circle of the pin sleeve are always subjected to high compressive stress, and the pin and the pin sleeve will be prematurely worn during operation. At the same time, the spring force of the guiding wheel tensioning spring also acts on the guiding axle and the bushing, which generates a large surface contact stress, which makes the guiding wheel bushing easy to be ground into a semicircle. The track section pitch is easy to lengthen and reduces mechanical transmission efficiency, wasting power transmitted by the engine to the drive wheels and tracks.
If the track is too loose, the track is easily disengaged from the guide wheel and the roller, and the track loses proper alignment, causing the running track to fluctuate, flap, and impact, causing abnormal wear of the guide wheel and the roller.
The track tension is adjusted by adding butter to the tensioning cylinder grease nozzle or releasing grease from the oil draining nozzle. Refer to the standard clearance of each model for adjustment. When the track section pitch is extended until a set of track sections needs to be removed, the meshing surface of the drive wheel tooth surface and the pin sleeve is also subject to abnormal wear. At this time, the method of maintaining the bulldozer should be properly treated before the meshing condition deteriorates. The method of maintaining the bulldozer is to turn the pin and the pin sleeve, replace the excessively worn pin and pin sleeve, and replace the track joint assembly, etc.
