Low-friction efficient driving wheel gear ring and implementation method thereof

Abstract

The invention discloses a low-friction efficient driving wheel gear ring, and belongs to the field of tank armored crawler vehicle propelling systems. The driving wheel gear ring comprises a gear ring base body, a self-lubricating antifriction block and a limiting baffle which are fixedly connected through mechanical limiting and welding processes. The self-lubricating anti-friction block serves as a supporting and friction contact piece for meshing driving of a driving wheel gear ring and a crawler belt, has the advantages of being low in friction coefficient and resistant to abrasion, and is particularly suitable for high-speed heavy-load crawler vehicles such as tanks adopting metal crawler belts. Compared with a driving wheel gear ring in the prior art, the provided driving wheel gear ring has the advantages of being low in friction coefficient and high in abrasion resistance, the abrasion speed of a driving wheel can be reduced, the service life of the crawler wheel gear ring can be prolonged, meanwhile, power loss of a driving wheel and crawler meshing pair can be reduced, and overall vehicle maneuverability and crawler meshing stability can be improved.

Description

technical field [0001] The invention belongs to the field of propulsion systems of tank armored track armored vehicles, and relates to a low-friction and high-efficiency driving gear ring gear, in particular to a composite structure driving gear ring gear matched with a metal track on a high-speed heavy-duty tracked vehicle. Background technique [0002] Tanks and tracked armored vehicles rely on the track propulsion system, which can greatly enhance their passing performance, so that the vehicles can smoothly pass through muddy swamps, mountain jungles and other soft ground and rough and rough roads. The crawler propulsion system relies on the transmission devices on both sides to transmit torque to the drive wheel ring gears on both sides, and the drive wheel ring gear engages the track and drives the track to move, thereby realizing the motion control of the tracked vehicle. It can be seen that the driving wheel ring gear is the key link and important component for the tr...
