Abstract
The invention discloses an unloading mechanism used on a motor output shaft. The unloading mechanism comprises a shaft sleeve positioned in the middle, wherein the outer sides of two ends of the shaft sleeve are sheathed with rotating bearings, an outer ring of each rotating bearing is embedded at the inner hole part of a support seat, an inlet and outlet hole of a transmission belt or a transmission chain is formed in each support seat, and wheels matched with the transmission belt or the transmission chain are fixedly sheathed in a position positioned at the outer sides of the shaft sleeve in inner cavities of the support seats. During the installation, the shaft sleeve is connected onto the motor output shaft through a key, a motor is fixedly connected with the side surfaces of the support seats through screws, the transmission belt or chain is sheathed on the wheels arranged at the outer sides of the shaft sleeve, the outer side of the shaft sleeve is provided with the bearings and the support seats, the load tension of the transmission belt or chain is completely born by the support seats, the motor output shaft only does rotary driving, the defect that the motor output shaft bears the radial load is overcome, the service life of the motor is prolonged, and the structure is simple.
Description
Technical field
The present invention relates to a kind of unloading mechanism, be mainly used on the output shaft of motor, remove the radial load that motor output shaft bears when operation.
Background technology
The output shaft of existing motor is directly connected with belt wheel or sprocket wheel, and belt wheel or sprocket wheel suit are fixed on the output shaft of motor, and during operation, load directly acts radially on motor output shaft, when load is excessive, easily causes the damage of electric machine main shaft bearing.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, motor output shaft not bearing radial force, extend the motor unloading mechanism in useful life, overcome the deficiencies in the prior art.
Unloading mechanism of the present invention, comprise the axle sleeve in the middle of being positioned at, outside, two ends at axle sleeve is set with rolling bearing, rolling bearing outer ring is embedded in the endoporus place of bearing, on bearing, be provided with the manhole appendix of driving-belt or driving-chain, at the inner chamber of bearing, be positioned at the outside of axle sleeve, fixed cover is equipped with the wheel matching with driving-belt or driving-chain.
Unloading mechanism of the present invention, during installation, axle sleeve is connected on the output shaft of motor by key, the side of bearing is screwed and is connected with motor, driving-belt or chain are enclosed within on the wheel in axle sleeve outside, and because there are bearing and bearing in axle sleeve outside, the load pulling force of driving-belt or chain is born by bearing completely, motor output shaft only rotarilys actuate, overcome the shortcoming that motor output shaft bears radial load, the useful life of having improved motor, simple in structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
As shown in Figure 1: 13 is motor, and 3 is axle sleeve, be fixedly set on the output shaft of motor 13 and connecting key is housed, at the ends screw of motor output shaft, being connected with shaft end nut 11.
Left end outside at axle sleeve 3 is provided with left bearing 1, and right-hand member outside is provided with right bearing 8, is radial ball bearing.The outer ring of left bearing 1 and right bearing 8 is set in the endoporus place of bearing 2, realizes the pretension of right bearing 8 by reconditioning adjusting pad 9 and compression bearing cap 10.On bearing 2, be provided with the manhole appendix 14 of driving-belt or driving-chain.At the inner chamber of bearing 2, the outside fixed cover that is positioned at axle sleeve 3 is equipped with the wheel 4 matching with driving-belt or driving-chain 12, takes turns 4 for belt pulley or sprocket wheel.Between the endoporus of wheel 4 and axle sleeve 3, be provided with tensioning sleeve 5 and be fixed by gland 7.
Bearing 2 sides are screwed and are connected with motor, driving-belt or chain 12 are enclosed within on the wheel 4 in axle sleeve 3 outsides, because there are bearing and bearing in axle sleeve 3 outsides, the load pulling force of driving-belt or chain 12 is born but not motor output shaft by bearing, motor output shaft only rotarilys actuate, overcome the shortcoming that motor output shaft bears radial load, the useful life of having improved motor, simple in structure.
