Description

Technical Field

[0001] The utility model relates to the technical field of reduction gearboxes, and more specifically, to a reduction gearbox with high stability. Background Art

[0002] A gear reduction box works based on the principle of connecting the prime mover to the reduction box, and then the reduction box to the working machine. It is a power transmission device. Generally, common prime movers include steam engines, electric motors, hydraulic motors, gas turbines, or internal combustion engines, etc. A prime mover is a machine that provides power. When there is a reduction drive, the prime mover provides power with high speed and low torque. Conversely, when there is a speed increase drive, the prime mover provides power with low speed and large torque. In mechanical transmission, the gear reduction box needs to drive its working object, the working machine, to achieve a predetermined purpose.

[0003] Existing gear reduction boxes are usually connected to other components by multiple screws. After long-term use, the screws are prone to loosening, which reduces the stability of the gear reduction box during use. Moreover, the loose connection will cause abnormal vibration during the operation of the equipment, which may cause further damage to other components. Chinese Patent with Publication No. CN213512000U discloses a reduction gearbox with high stability, which proves the objective existence of this drawback.
