Description

Technical Field

[0001] The utility model relates to the technical field of wheel-side reducers, and in particular to a lightweight wheel-side reducer that is easy to install. Background Art

[0002] As the final transmission device of the cotton picker drive axle transmission system, the wheel-side reducer has the function of reducing speed and increasing torque, which is of great significance for improving the system's carrying capacity and reducing the size of the entire drive axle.

[0003] Cotton pickers require a large final drive ratio and high ground clearance. Therefore, wheel-side reducers are typically installed close to the drive wheels to meet power and maneuverability requirements. This also improves the picker's driving force to meet or correct the overall transmission system's force matching, especially in applications requiring greater ground clearance and a higher final drive ratio.

[0004] However, wheel-side reducers under the existing technology are usually installed by bolt fixing, which is very inconvenient. In addition, traditional wheel-side reducers usually adopt planetary gear type, which has a complex structure and high cost, is difficult to maintain, and makes a lot of noise when running at high speed.
