Description

Technical Field

[0001] The utility model relates to the technical field of reduction gear boxes, in particular to a reduction gear box. Background Art

[0002] The gear reducer works on the principle that the prime mover is connected to the reduction gearbox, which is then connected to the working machine. It is a power transmission device. Commonly used prime movers include steam engines, electric motors, hydraulic motors, gas turbines, internal combustion engines, etc. The prime mover is a machine that provides power. When there is a reduction transmission, the prime mover provides high-speed, low-torque power. Conversely, when there is a speed-increasing transmission, the prime mover provides low-speed, high-torque power. In mechanical transmission, the gear reducer needs to drive its working object.

[0003] Existing gear reducers rely on only a single gear for meshing and reduction transmission. Although this improves torque, it lacks the 90-degree synchronous positioning effect when rotating the output shaft in actual use, making it relatively bulky when performing reduction transmission on precision equipment.
