AI Technical Summary

Technical Problem

The existing tools for disassembling and assembling the balance shaft support sleeve of tracked vehicles are inefficient, labor-intensive, have limited operating space, pose safety hazards, and are difficult to clean effectively. They are also prone to corrosion, jamming, or deformation, especially after long-term use or high-load operation.

Method used

The disassembly and assembly tools utilize a combination of an electric wrench and a swivel plate, along with features such as a splash guard, an energy-absorbing sponge layer, and a sealing ring. Through mechanical linkage, the support sleeve can be rotated at high speed and disassembled quickly. It is equipped with a cleaning plate and a dedicated rotating disassembly device to ensure cleanliness and stability.

Benefits of technology

It enables quick disassembly of the balance shaft, reduces the risk of steel ball and impurity splashing, improves disassembly and assembly efficiency, extends tool life, and simplifies maintenance.

Abstract

This utility model discloses a tool for disassembling and assembling a balance shaft support sleeve for tracked vehicles, belonging to the field of tracked vehicle maintenance technology. It includes a splash guard and a base. A connecting plate is mounted on the base, and a support sleeve is mounted on one side of the connecting plate. A balance shaft is located inside the support sleeve, and a cylinder is mounted inside the splash guard. The balance shaft is coaxially aligned with the cylinder and located at the bottom of the cylinder. A bearing is located at the top of the cylinder, and a perforated plate is provided between the bearing and an electric wrench. The electric wrench is mounted on the bearing. A weight-reducing hole is opened on the front side of the cylinder. Stable mechanical linkage is achieved by inserting a pin 8 into the mating hole of the support sleeve 10. Driven by the electric wrench, the pin drives the support sleeve 10 to rotate at high speed, completing the disassembly of the balance shaft 9. The tool, through the cooperation of a dedicated disassembly device 6 and a return spring 7, ensures that the support sleeve 10 can quickly return to its original position after disassembly.
