The height of the bearing fixing sleeve is less than or equal to the height of the two first bearings, so that the bearing and the bearing fixing sleeve can be conveniently mounted, dismounted and replaced.

Optionally, a second bearing is arranged at the free end of the output shaft, an oil seal ring is arranged between the second bearing and the box body, and the oil seal ring is sleeved on the output shaft. The second bearing can reduce the abrasion of the other end of the output shaft, and can play a role in sealing by using the oil seal ring.

Optionally, the shift shafts include a first shift shaft and a second shift shaft, and the first shift shaft and the second shift shaft are arranged on the box body in parallel. The first speed changing shaft and the second speed changing shaft can realize two-stage speed changing, and the speed changing effect is better and more stable.

Optionally, the first speed-changing shaft is provided with a third bearing, and the third bearing is arranged at two ends of the first speed-changing shaft. Set up the third bearing on the first variable speed axle, the third bearing plays the effect that reduces friction, increases first variable speed axle's life to a certain extent.

Optionally, a fourth bearing is disposed on the second speed-changing shaft, and the fourth bearing is disposed at two ends of the second speed-changing shaft. Similarly, the second speed changing shaft is provided with a fourth bearing, and the fourth bearing plays a role in reducing friction, so that the service life of the first speed changing shaft is prolonged to a certain extent.

Optionally, the first bearing, the third bearing and the fourth bearing are ball bearings, and the second bearing is a cylindrical roller bearing.

The utility model discloses following beneficial effect has: the motor operation drives the input shaft and rotates, and the input shaft rotates and drives change gear to rotate to drive the output shaft and rotate, because set up two first bearings at the stiff end of output shaft, and two first bearings are fixed in the bearing fixed sleeve, fix two first bearings through the bearing fixed sleeve, greatly increased the life of output shaft.
