Description

Technical Field

[0001] The utility model belongs to the technical field of reducers, and specifically relates to an upright reducer. Background Art

[0002] A reducer, also known as a reduction gear, is an independent enclosed transmission device between a motor and a working machine. Its core function is to reduce the speed and increase the torque, and it can also be used as a speed increaser in specific situations. The following is a detailed introduction to the reducer: Reducing speed: Through the transmission of gears inside the reducer, the input high-speed rotation is converted into a lower-speed output. Increasing the output torque: While reducing the speed, the output torque increases accordingly to meet the torque requirements of mechanical equipment. Reducing the inertia of the load: Making the mechanical equipment more stable when starting, stopping, or changing the motion state. The working principle of the reducer is based on the meshing of gears with different numbers of teeth. When the output speed of the motor is input from the driving shaft, it drives the small gear to rotate, and the small gear then drives the large gear to move. Since the number of teeth of the large gear is more than that of the small gear, the rotation speed of the large gear is slower than that of the small gear, and it is output from the shaft (output shaft) of the large gear, thus playing a role in speed reduction. Through multi-stage gear transmission, the deceleration effect can be further increased and the output torque can be increased.

[0003] In the existing rear axle of a beach vehicle, it is installed horizontally. With the development of electrification, beach vehicles are gradually developing towards the electrification direction. The existing beach vehicles are electrically driven, and the reducer is not integrated with the rear axle. Moreover, the reducer and the rear axle are arranged separately, which will occupy more space, making the overall layout of the vehicle not compact enough. Complex installation: The scattered components increase the difficulty of installation and debugging, and may also lead to the accumulation of errors during the installation process. Longer transmission chain: The non-integration of the reducer and the rear axle means that the transmission chain is relatively long, and more energy losses will occur during the transmission process, thus reducing the transmission efficiency. Additional friction: The longer transmission chain may also introduce additional friction and vibration, further affecting the transmission efficiency and the smoothness of the vehicle. Redundant components: The scattered reducer and rear axle may require additional connecting parts and support structures, thus increasing the overall weight of the vehicle. Material consumption: The non-integrated design may lead to sub-optimal use of materials, resulting in unnecessary waste. Increased failure rate: The scattered components may increase the failure points and raise the failure rate, requiring more frequent maintenance and repair. Difficulty of maintenance: The complex layout and scattered components may increase the difficulty and cost of maintenance, especially in the wild or harsh environments. Summary of the Utility Model
