Abstract
A kind of driving wheel protective device, including transmission shaft, one end of transmission shaft is arranged with expansion tightening wheel, expansion tightening wheel excircle is arranged between traveling wheel and expansion tightening wheel and traveling wheel and is fixed by jackscrew, it further include circular cover, first plain washer, the first spring, second spring and the second plain washer, at least two threaded holes are symmetrically arranged on transmission shaft, circular cover is equipped with screw rod compatible with threaded hole, and screw rod is successively locked in the threaded hole of transmission shaft after the first plain washer of drawing-in, the first spring, circular cover, second spring and the second plain washer.After traveling wheel and expansion tightening wheel are installed by jackscrew, in transmission shaft head radius midpoint, circumferentially equal part is punched, and installation one can cover the circular cover of jackscrew, press jackscrew, jackscrew is made not fall off outward because of loosening.
Description
Technical field
The utility model relates to mechanical transmissions, more particularly to a kind of driving wheel protective device.
Background technique
In tobacco processing cabinet class equipment, the stone vehicle of top drives transmission shaft movement, transmission shaft both sides peace by motor
Driving wheel is filled, transmission shaft drives driving wheel to travel along guide rail.However in moving back and forth cloth process, due to vibration etc.,
After causing expansion tightening wheel jackscrew to loosen, traveling wheel and axis are loosened and are detached from, and damage traveling wheel.Machine halt trouble is caused, exists and greatly sets
Standby failure and safety hazards, also have significant effect processing quality.
Utility model content
In order to overcome the drawbacks of the prior art, the utility model provides a kind of driving wheel protective device.
Based on above-mentioned purpose, the utility model adopts the following technical scheme: a kind of driving wheel protective device, including transmission
Axis, one end of transmission shaft are arranged with expansion tightening wheel, and expansion tightening wheel excircle, which is arranged between traveling wheel and expansion tightening wheel and traveling wheel, to be passed through
Jackscrew is fixed, and further includes circular cover, the first plain washer, the first spring, second spring and the second plain washer, symmetrical on transmission shaft
Equipped at least two threaded holes, circular cover is equipped with screw rod compatible with threaded hole, screw rod successively the first plain washer of drawing-in, the
It is locked in the threaded hole of transmission shaft after one spring, circular cover, second spring and the second plain washer.
Further, four threaded holes are symmetrically arranged on the transmission shaft.
Further, the distance between the threaded hole and the transmission shaft center of circle are equal to the half of transmission shaft radius.
Further, the diameter of the circular cover is greater than the distance between jackscrew and the transmission shaft center of circle.
After traveling wheel and expansion tightening wheel are installed by jackscrew, in transmission shaft head radius midpoint, circumferentially equal part is beaten
Hole, installation one can cover the circular cover of jackscrew, press jackscrew, jackscrew is made not fall off outward because of loosening.This is practical
It is novel to be arranged with the first spring and second spring above and below in circular cover, circular cover and transmission shaft are divided into two independences
Vibrational system, reduce transmission shaft, expansion tightening wheel and traveling wheel vibrate influence to circular cover, increase the stabilization of circular cover
Property.
The utility model has the advantage of avoid jackscrew from loosening, eliminate to equipment by setting circular cover and spring
Influence, facilitate adjusting, improve the reliability in system work process, the utility model structure is simple, practical function, investment
It is few, there is good industrial application value and popularization and application foreground.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that circular cover is assembled the structural schematic diagram on transmission shaft.
Specific embodiment
The technical solution of the utility model is described in further details below in conjunction with attached drawing.
A kind of driving wheel protective device, including transmission shaft 1, one end of transmission shaft 1 are arranged with expansion tightening wheel 2,2 outer circle of expansion tightening wheel
It is arranged in week between traveling wheel 3 and expansion tightening wheel 2 and traveling wheel 3 and is fixed by jackscrew 4, further include circular cover 6, the first plain washer
81, the first spring 91, second spring 92 and the second plain washer 82 are symmetrically arranged with four threaded holes 5, circular cover 6 on transmission shaft 1
Equipped with offer the perforation 61 passed through for screw rod 7 in the compatible screw rod 7(circular cover 6 of threaded hole 5), screw rod 7 is successively worn
The spiral shell of transmission shaft 1 is locked after the first plain washer 81, the first spring 91, circular cover 6, second spring 92 and the second plain washer 82
In pit 5.
The distance between 1 center of circle of the threaded hole 5 and transmission shaft is equal to the half of 1 radius of transmission shaft.
The diameter of the circular cover 6 is greater than the distance between 1 center of circle of jackscrew 4 and transmission shaft.
Expansion tightening wheel 2 is set on transmission shaft 1, traveling wheel 3 and expansion tightening wheel 2 are connected by 4 four jackscrews 4, and jackscrew 4 rises
To making expansion tightening wheel 2 and the close-connected effect of traveling wheel 3.In circumference equal dividing design of 1 spindle nose of transmission shaft from center of circle half
Four threaded holes 5；Circular cover 6 is formed by 2 millimeters of thickness of stainless steel cut, reaches certain intensity, right in circular cover 6
Answer Position Design 4 perforation 61；Circular cover 6 is tightly coupled on 1 spindle nose of transmission shaft by being fixedly connected with bolt 1, is realized
Purpose is protected, meanwhile, it is arranged with the first spring 91 and second spring 92 above and below in circular cover 6, by circular cover 6 and transmission
Axis 1 is divided into two independent vibrational systems, reduces transmission shaft 1, expansion tightening wheel 2 and the vibration of traveling wheel 3 to the shadow of circular cover 6
It rings, increases the stability of circular cover 6.
