Background technique
The driven sprocket structure that accumulates the driving machine in the type stepping shot blasting machine system of former factory as described in Figure 1, this driven sprocket mechanism is by circlip for shaft 7, driven sprocket 5, model is 8109 thrust ball bearing 3, sprocket shaft 4 forms, one end of sprocket shaft 4 is fixed on the driving machine support 9 by nut 8, the other end is arranged with thrust ball bearing 3 and driven sprocket 5, thrust ball bearing 3 supports an end of driven sprocket 5, the other end of driven sprocket 5 is provided with circlip 7, sprocket wheel on this sprocket shaft only supports by thrust ball bearing 3, and this thrust ball bearing mainly plays supporting effect in vertical direction, and the driven sprocket operation is not steady in the running, especially in the horizontal direction, hole in the middle of sprocket shaft and the driven sprocket constantly rubs, and is that the continuous change of center hole of driven sprocket is scrapped greatly at last, and the driving mechanism rate of fault is high.
The model utility content
For deficiency of the prior art, the utility model aims to provide a kind of driven sprocket mechanism of step-by-step movement shot blasting system drive machine, so that the operation of the driven sprocket in this driven sprocket mechanism is more steadily reliable, reduce the friction between driven sprocket and the sprocket shaft, improve its working life.
In order to address the above problem, the driven sprocket mechanism of a kind of step-by-step movement shot blasting system drive machine of the present utility model, comprise: the live axle support, sprocket shaft, driven sprocket and thrust ball bearing, one end of sprocket shaft is fixed on the live axle support by nut, the other end is arranged with thrust ball bearing and driven sprocket, this thrust ball bearing is arranged in the first step part of driven sprocket bottom, the driven sprocket mechanism of this step-by-step movement shot blasting system drive machine is characterised in that: also comprise a ball bearing and a bearing (ball) cover, the top of described driven sprocket has the second step part, this ball bearing passes described sprocket shaft and is arranged in this second step part, bearing (ball) cover respectively with the bearing outer ring of ball bearing and the top butt of driven sprocket.
Preferably, also comprise a setting sleeve and a circlip, this setting sleeve passes described sprocket shaft and is arranged between the bearing inner race of sprocket shaft outer wall and described ball bearing, circlip pass described sprocket shaft and with the setting sleeve butt.Described ball bearing is deep groove ball bearing.
The utility model has been set up a deep groove ball bearing coaxial with thrust ball bearing on former factory chain sprocket structure basis, this deep groove ball bearing set up the frictional force of having eliminated between sprocket hole and the sprocket shaft, so that sprocket wheel is steadily reliable in running, rate of fault reduces greatly.It is more reasonable that driven sprocket mechanism of the present utility model compares to former factory sprocket wheel.Usability and life-span improve greatly.Written-off sprocket wheel is reused, avoided former factory chain sprocket structure unreasonable, sprocket wheel is frequently scrapped and the waste of the cost that brings.

Embodiment
Below in conjunction with accompanying drawing to this practical being described further.
As shown in Figure 2, the driven sprocket mechanism of step-by-step movement shot blasting system drive machine of the present utility model comprises: live axle support 9, sprocket shaft 4, driven sprocket 5, thrust ball bearing 3, ball bearing 2 and bearing (ball) cover 1.One end of sprocket shaft 4 is fixed on the live axle support 9 by nut 8, the other end is arranged with thrust ball bearing 3 and driven sprocket 5 from the bottom to top successively, this thrust ball bearing 3 is arranged in the first step part 51 of driven sprocket bottom, and offset with step on sprocket shaft 4 ends, this thrust ball bearing is used for supporting driven sprocket.The top of this driven sprocket 5 also has the second step part 52, here the top of driven sprocket relatively and the bottom, top and bottom is relative.This ball bearing 2 passes described sprocket shaft 4 and is arranged in this second step part 52, bearing (ball) cover 1 respectively with the bearing outer ring of ball bearing 2 and the top butt of sprocket shaft, be that protuberance below the bearing (ball) cover and the bearing outer ring of ball bearing offset, end cap covers the second step part and offsets with the sprocket shaft top, and the ball bearing in the second step part is played fixing and seal action.
This driven sprocket mechanism also comprises a setting sleeve 6 and a circlip 7, this setting sleeve 6 passes between the bearing inner race that described sprocket shaft 4 is arranged on sprocket shaft 4 outer walls and described ball bearing 2, be used for better fixedly ball bearing 2, further reduce the slit between driven sprocket 5 and the sprocket shaft 4, so that the driven sprocket operation is more steadily reliable.Circlip 7 passes described sprocket shaft 4 and setting sleeve 6 butts, plays the effect of certain seal protection.Preferably, described ball bearing 2 is deep groove ball bearing, and model is 209.Descaling machine in this step-by-step movement shot blasting system is that Q588 accumulates type stepping shot blasting machine.
Having set up one is 209 deep groove ball bearing 2 on former factory chain sprocket structure basis with the coaxial model of thrust ball bearing 3, bearing peripheral hardware bearing (ball) cover 1 and bearing inner race setting sleeve 6, model is that the circlip for shaft 7 of φ 45 is close to bearing inner race setting sleeve 6, be used for fixing bearing inner race setting sleeve 6, deep groove ball bearing 2 set up the frictional force of having eliminated between sprocket hole and the sprocket shaft 4, so that sprocket wheel is steadily reliable in running, rate of fault reduces greatly.It is more reasonable that driven sprocket mechanism of the present utility model compares to former factory sprocket wheel.Usability and life-span improve greatly.Written-off sprocket wheel is reused, avoided the former factory unreasonable sprocket wheel of chain sprocket structure frequently to scrap, saved the waste of operation and maintenance cost.
