Tension and relaxation of track of RP952 asphalt concrete paver

The running mechanism of RP952 asphalt paver usually does not require maintenance. It is only necessary to check whether the track is tight or too tight or too loose, which will speed up the wear of the track. The pin and the pin sleeve is glidingly matched, tracked Zhang them tight, between the pin and the pin sleeve pressure is, the more severe wear. Therefore, the track should not be too tight. When the track has the correct tensioning force, the clearance of the gasket is about 1~5mm.

A caterpillar is not tight, will also speed up the wear track, when paver back, does not allow the driving wheel gear top and a sleeve to collide, move freely, if a collision occurs, the tooth and the sleeve will soon wear. The track will be too loose in the machine direction when the guide wheel and supporting wheel on the track strongly move, which will also cause the premature damage of track.

The wear between the pin and sleeve, generally occurs in the direction of the pulling force of the track, the wear of the track pitch increases, and the driving wheel cannot match, so must pay attention to, track and drive wheel should be replaced, the old and new tracks can't drive wheel pair.

The track is tensioned by a tensioning device, consisting of a grease cylinder and a pre tensioned spring.

Track tensioning, the one-way valve with a lubrication hose, hose connection and lubricating grease gun, grease gun into the cylinder through the pressure grease, make the oil cylinder to move forward, so as to promote the guide wheel to move forward, to keep the right track tension.
