Abstract

The invention relates to the technical field of motors, in particular to a motor gear shaft system and a motor comprising the motor gear shaft system.The motor gear shaft system comprises a gear shaft used for installing an input shaft gear, one end of the gear shaft is connected with a motor rotor shaft, and the other end of the gear shaft is assembled with a bearing seat on a reduction gearbox shell cover through an auxiliary bearing; a gap is formed between the outer ring of the auxiliary bearing and the bearing seat, two spaced sealing rings are arranged in the gap, a closed space is defined by the two sealing rings, the outer ring of the auxiliary bearing and the bearing seat, and the closed space is filled with damping liquid. Therefore, an extrusion oil film damper is formed, the extrusion oil film damper can have a good vibration reduction effect on the gear shaft, and therefore vibration of a gear shaft system can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor gear shaft system and a motor including the motor gear shaft system. Background technique [0002] The gear box equipped with the motor is mostly geared. The input shaft of the gear box is used as the gear shaft to install the input shaft gear. One end of the gear shaft is connected to the rotor shaft of the motor, and the other end of the gear shaft is installed on the reduction housing cover. In the prior art, the motor-driven gear shaft system usually has the problem of relatively large vibration. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a motor gear shaft system capable of effectively reducing vibration, so as to overcome the above-mentioned defects in the prior art. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: [0005] The...
