Abstract
The utility model discloses a reducing motor. The reducing motor comprises a box body, a motor, an intermediate shaft and an output shaft, wherein the motor shaft drives the intermediate shaft through gear reduction; the intermediate shaft drives the output shaft through gear reduction; and the intermediate shaft and the output shaft are arranged in the box body in a slewing manner. The reducing motor is characterized in that the output shaft arranged in the box body in a slewing manner is provided with three bearing supports, one is a thrust ball bearing support arranged at the part of the output shaft, which is extending out of the box body, and the other two are deep-groove ball bearing supports arranged on two sides of an output gear. The reducing motor can bear an axial thrust, is applied on occasions where axial thrusts exist, and can shorten the axial mounting dimension of equipment.
Description
[technical field]
The utility model relates to a kind of improvement invention of reducing motor.
[background technology]
Reducing motor is exactly a kind of motor that carries decelerator, and the reducing motor compact conformation is widely used; But; The maximum deficiency of reducing motor is can not bearing axial pushing force, so reducing motor need be installed independently bearing thrust device in addition in some workplaces that have axial thrust to require of petroleum chemical industry between reducing motor and connection device (like screw pump); So; Not only the axial dimension installed of equipment will have bigger increase, and the equipment profile after installing will seem heavy, and profile is not attractive in appearance.
[summary of the invention]
To the deficiency that prior art exists, the purpose of the utility model aims to provide the reducing motor of a kind of ability bearing axial pushing force, shortening equipment installation axial dimension.
The utility model takes following technical scheme to accomplish:
A kind of reducing motor comprises casing, motor, jack shaft and output shaft, and motor shaft is through gear reduction transmission jack shaft; Jack shaft is through the gear reduction transmission output shaft, and jack shaft, output shaft turn round setting in casing, it is characterized in that: the output shaft that revolution is provided with in casing has the bearing supporting of three places; One place is the thrust ball bearing supporting; Position at the overhanging casing of output shaft is provided with, and two places are the deep groove ball bearing supporting, are provided with in the both sides of output gear.
After adopting technique scheme; The output shaft of reducing motor not only has the two places deep groove ball bearings supporting (deep groove ball bearing can only bearing radial force, basically can not bearing axial pushing force) of prior art, and (thrust ball bearing can not bearing radial force to have had place thrust ball bearing supporting simultaneously; But can bear very big axial thrust); So, the reducing motor of the utility model is the ability bearing axial pushing force just, has solved the deficiency that prior art exists; In addition, the reducing motor of installed thrust ball bearing, its axial dimension have just increased the installation site size of thrust ball bearing; The axial dimension of reducing motor changes little; If the utility model is used in the workplace that petroleum chemical industry has axial thrust to require, can omit the bearing thrust device of installing in addition between reducing motor and the connection device, so; The axial dimension installed of shortening equipment greatly not only, and the equipment profile after installing will seem attractive in appearance.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
[embodiment]
Come the utility model is explained in detail and explains through specific embodiment below:
With reference to Fig. 1, the reducing motor of the utility model comprises casing 3, motor 1, jack shaft 2 and output shaft 4; Motor shaft 9 is through gear reduction transmission jack shaft 2, and jack shaft 2 is through gear reduction transmission output shaft 4, and jack shaft 2, output shaft 4 turn round setting in casing 3; The output shaft 4 that revolution is provided with in casing has the bearing supporting of three places, and a place is thrust ball bearing supporting 5, is provided with at the position of output shaft 4 overhanging casings 3; Two places are deep groove ball bearing supporting 6 and 8, are provided with in the both sides of output gear 7.So can bear unidirectional axial thrust, there is the applications of axial thrust in the utility model because thrust ball bearing 5 has been installed, the axial dimension of can shortening equipment installing.
