Specific embodiment
It is specific below in conjunction with the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
It is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to the utility model
The range of protection.
Below in conjunction with attached drawing, technical solution provided by the embodiment of the utility model is described in detail.
As shown in the picture, the utility model embodiment provides a kind of Main Drive of Rolling Mill universal shaft, the Main Drive of Rolling Mill ten thousand
Include driving shaft 1, universal joint 2 and end cap 3 to axis, further includes the positioning pin 4 and bolster being mounted between end cap 3 and driving shaft 1
5.Positioning pin 4 includes cup dolly 401 and the pin 402 being arranged in 401 end face center of cup dolly, the plunger of pin 402
For ball head structure, positioning pin 4 is detachably secured to end cap 3 by cup dolly 401, and 1 axis body end face of driving shaft is set along axial direction
It is equipped with locating slot compatible with pin 402, the inner bottom surface of plunger and locating slot offsets；Bolster 5 is circular gasket, bolster
5 end face centers are provided with installation through-hole 501 compatible with pin 402, and bolster 5 is set in pin 402, the end of bolster 5
Face and the spindle nose end face of driving shaft 1 offset.
The working principle of Main Drive of Rolling Mill universal shaft provided by the embodiment of the utility model is illustrated below:
Positioning pin 4 is fixed on end cap 1, and pin 402 and the locating slot on 1 spindle nose of driving shaft of positioning pin 4 are engaged,
To meet axial positioning requirements in the operation of rolling；Simultaneously as the plunger of pin 402 is ball head structure and locating slot and pin
402 are adapted, and at work, no matter how angle changes, the inner bottom surface of the plunger of pin 402 and locating slot is always for the universal shaft
Keep sphere-contact thus, it is possible to increase the contact area of pin 402 Yu driving shaft 1 to reduce the rate of wear of plunger, avoid because
Abrasion causes the axial motion of driving shaft 1 apart from the normal production for increasing and influencing milling train.Meanwhile when the pin of positioning pin 4 402
When wearing, using the bolster 5 being sleeved on pin 402, the axial position of driving shaft 1 can be defined, and dropped
Countervail the wearing- in period of column 402, and driving shaft 1 is avoided to occur the vibration of big distance in the axial direction, extends the deterioration of axial motion phenomenon
Time.
As it can be seen that Main Drive of Rolling Mill universal shaft provided by the embodiment of the utility model between driving shaft 1 and end cap 3 by being arranged
Positioning pin 4 and bolster 5 are acted on, energy with forming twin-stage protection using the wear-resistant effect of plunger and the elastic buffer of bolster 5
The abrasion for enough avoiding 1 spindle nose end face of driving shaft and end cap 3 and interior external tooth, extends the service life of universal shaft, it is ensured that 1 axis of driving shaft
To the reliability and transmission stability of position, maintenance replacing construction is reduced, the production efficiency of milling train is improved.
Wherein, the thickness of bolster 5 is according to the axial movement distance of the permitted driving shaft 1 of milling train in actual production, with
