Performance parameter

 

Roller wheel body materials are generally 50Mn, 40Mn2,etc. The main process is casting or forging, machining, and then heat treatment. The hardness of the surface of the wheel after quenching should reach HRC45 ~ 52 to increase the wear resistance of the wheel surface. The processing precision of roller axles is relatively high. Generally, CNC machine tools are required to meet the requirements. The material is more than 40Mn2. After processing, it is also required to be quenched and heat treated, and the hardness reaches about HRC42.

 

Use and maintenance


After the operation, did the operator clean the sludge on the lower traveling body while cleaning the cab? If sludge is attached to the lower traveling body. It is not possible to perform an inspection of its related parts. Therefore, be sure to remove these sludges and inspect and maintain the lower traveling body. Are the bolts loose? Can the sprocket and track roller not rotate? Are there oil leaks from the sprocket, track roller and drive wheels?

Precautions for Track Roller Replacement


1. After cleaning the dirt on the walking frame, park the device on a flat area.

 

2. Use a wrench to loosen the pressure-blocking cylinder's pressure relief plug of the walking frame, and loosen it no more than 1 turn to prevent the high-pressure grease from spraying and hurting people.


3. Use the working device (big arm cylinder) to support the vehicle body, lift the track pads, and use a pneumatic wrench to loosen the track cover wheel cap screws, but do not completely remove the screws.


4. Raise the boom cylinder, lower the track pads, and support the track pads with the track rollers. Loosen the screws to remove the tile cover, support the vehicle body again, and lift out the track rollers.


5. Install the track rollers in the order of disassembly. The roller screws are coated with copper powder to prevent rust. After screwing it in place with a pneumatic wrench, the pound meter (torque tool) can be adjusted to increase the pound.


6. After the high-pressure grease is injected into the telescopic cylinder of the walking frame, the standard value is measured during forward and backward travel. The gap at a is about 10 ~ 30mm.
