Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of speed reducer equipment, in particular to a coaxial speed reducer connecting transmission structure. BACKGROUND

[0002] The speed reducer is also called speed reducer, which is installed between the original motor and the working machine, and is used for reducing the rotating speed and increasing the torque. In the single-stage speed reducer connecting transmission structure, the transmission ratio is limited due to the single-stage transmission, and it is difficult to meet the working conditions requiring large reduction ratio, which is determined by the structural characteristics. In terms of carrying capacity, due to the fewer key components such as gears, when transmitting large power, wear, deformation and even fracture are prone to occur. During operation, the impact generated by gear meshing is large, resulting in obvious vibration and noise problems. In order to solve the problem of insufficient carrying capacity, the gear size and modulus are often increased, which increases the volume and weight of the speed reducer, occupies more space, and for vibration and noise, high-precision gears and optimized tooth shape are generally used, which greatly increases the processing cost. In order to reduce wear, a complex lubrication system is often required, which not only increases the cost, but also increases the maintenance difficulty, and once the lubrication system fails, the gear wear is aggravated, so a new structure is needed to solve the above technical problems.
