Komatsu crawler Excavator and dozer undercarriage parts tension idler working principle
Butter injected into the cylinder through the butter nozzle with a butter gun, so that the piston extends outward to push the tension spring, and the idler guide wheel moves left to tighten the track chain with shoe assembly. The tightening spring has an appropriate travel. When the tension force is too large, the spring is compressed to act as a buffer; when the tension force is too large disappears, the compressed spring pushes the guide wheel in place, It can ensure the sliding along the crawler frame to change the wheelbase, ensure the disassembly and assembly of the crawler, reduce the impact of the walking process, and avoid derailment of the track chain.
