When the planetary reducer is used in the driving device of the overhead passenger device, a bearing seat needs to be installed on the driving wheel of the driving device, and the load driving shaft is arranged in the bearing seat. One end of the load driving shaft is connected to the output shaft of the planetary reducer, and the other end is connected to the drive shaft. There is a connecting seat between the planetary reducer and the bearing seat, but due to the deformation of the connecting seat itself and the relationship of many mating surfaces, it is difficult to ensure the coaxiality of the load drive shaft and the output shaft of the planetary reducer. It is easy to cause wear of the output shaft and the load drive shaft, seriously affecting the service life of the reducer, and there are also serious safety hazards such as broken shafts.

The invention discloses a planetary speed reducer with a bearing seat. The planetary speed reducer with the bearing seat comprises a planetary speed reducer and the bearing seat, wherein a load driving shaft is arranged in the bearing seat; a bearing is arranged between the load driving shaft and the bearing seat; the planetary speed reducer is directly connected with the bearing seat through matching; and an output shaft of the planetary speed reducer is connected with the load driving shaft in the bearing seat through splines. The planetary speed reducer with the bearing seat has the technical effects that through adopting the manner that the bearing seat is directly connected with a speed reducer body through matching, the coaxiality of the load driving shaft and the output shaft of the planetary speed reducer is guaranteed more easily, so that the abrasion of the load driving shaft and the output shaft is avoided, the service life of the speed reducer can be prolonged, the hidden danger of relatively serious safety accidents such as shaft breaking can be greatly reduced, and an aerial passenger device is guaranteed to steadily operate.
Description
technical field [0001] The invention relates to a speed reducer, in particular to a planetary speed reducer. Background technique [0002] The planetary reducer is used to connect between the prime mover and the working machine or the actuator, and mainly plays the role of matching speed and transmitting torque. When the planetary reducer is used in the driving device of the overhead passenger device, a bearing seat needs to be installed on the driving wheel of the driving device, and the load driving shaft is arranged in the bearing seat. One end of the load driving shaft is connected to the output shaft of the planetary reducer, and the other end is connected to the drive shaft. There is a connecting seat between the planetary reducer and the bearing seat, but due to the deformation of the connecting seat itself and the relationship of many mating surfaces, it is difficult to ensure the coaxiality between the load drive shaft and the output shaft of the planetary reducer. ...
