Abstract
The utility model relates to a device for preventing the axial float of a cross shaft of a universal shaft coupling. The technical scheme is that: the center of a bearing outer sleeve is provided with a through hole; a shaft head end surface of the cross shaft is provided with a threaded hole; one to four wear-resistant disk springs are arranged in an adjusting pad; and a bolt equipped with a wear-resistant pad penetrates through the through hole of the bearing outer sleeve and the threaded hole. The threaded hole is formed in such a way that wear-resistant disk springs are screwed into the shaft head of the cross shaft. The device for preventing the axial float of the cross shaft of the universal shaft coupling has following beneficial effects: abrasion degree of the adjusting pad is reduced; and occurrence of the axial float of the cross shaft is effectively avoided.
Description
Affiliated field
The utility model relates to a kind of engineering goods Hooks coupling universal coupling, specifically a kind of device that prevents Hooks coupling universal coupling cross axle axial float.
Background technique
In recent years, with the universal coupling with spider of rolling bearing, because it has, transmitting torque is large, to allow to transmit inclination angle large, the advantages such as transmission efficiency is high and steady, gap impact is little, be applicable to run up, have been applied to the industry extensive uses such as mine, metallurgy widely.By the use of universal coupling with spider, find that spindle swings larger, cause set of rollers bearing outside to damage, cross bag finds that cross axle exists larger axial float on inspection.Through disintegration universal-joint spindle cross bag, find that it is to cause for adjusting the spacer wearing and tearing of axial clearance that generation axle is altered reason, after spacer serious wear, excesssive gap cross axle just produces axial float, causes set of rollers bearing damage, because this reason causes Hooks coupling universal coupling too early along bad.
Summary of the invention
The purpose of this utility model is: design a kind of device that prevents Hooks coupling universal coupling cross axle axial float.
The technical solution of the utility model is achieved in that
Hooks coupling universal coupling is combined by cross bag and jaw.The bearing outside of cross bag and jaw endoporus are to adopt transition fit to assemble, thereby reach the object that the radial clearance of universal joint is bearing end-play; Endoporus at jaw running in bearings overcoat has interior jump-ring slot in the outer part, and bearing installs to be fixed afterwards with jump ring, and the outside play of restriction bearing outside, plays axial restraint.Cross bag is comprised of a cross axle and four roller bearings, bearing outside, spacers, on each spindle nose of cross axle, overlap roller bearing, roller bearing outboard bearing overcoat, between each spindle nose end face of cross axle and bearing outside interior edge face, spacer is housed, the axial clearance of cross axle has spacer adjustment, excessive for preventing spacer wearing and tearing post gap, this programme is: bearing outside center is provided with to through hole; Cross axle spindle nose end face center is provided with tapped hole; The wear-resisting dish spring of the in-built 1-4 part of spacer (can purchase tender); With a bolt with wear-resistant pad, through bearing outside through hole, wear-resisting Die Huang center, be screwed into cross axle spindle nose tapped hole.During assembling, elasticity bolt adjusting play size, is coated with fixing glue spindle nose tapped hole planted agent, prevents bolt looseness.The effect of dish spring is to carry out the axial clearance producing after the wearing and tearing of compensation adjustment pad to the mode of cross axle interpolation pretightening force.
The beneficial effects of the utility model are: reduced the spacer degree of wear, effectively prevented that cross axle axial float phenomenon from occurring.

Specific embodiment
Hooks coupling universal coupling is combined by cross bag (2) and jaw (1).Cross bag (2) is comprised of a cross axle (9) and four roller bearings, bearing outside (3), spacers (4), on each spindle nose of cross axle (9), overlap roller bearing, roller bearing outboard bearing overcoat (3), is equipped with spacer (4) between each spindle nose end face of cross axle (9) and bearing outside (3) interior edge face.This programme is: bearing outside (3) center is provided with to through hole; Cross axle (9) spindle nose end face center is provided with tapped hole (8); The wear-resisting dish spring of the in-built 1-4 part of spacer (4) (5); With the bolt (6) of a band wear-resistant pad (7), through bearing outside (3) through hole, wear-resisting dish spring (5) center, be screwed into cross axle (9) spindle nose tapped hole (8).Elasticity bolt during assembling (6) adjusting play size, is coated with fixing glue spindle nose tapped hole (8) planted agent, prevents that bolt (6) is loosening.
Claims (1)
1. a device that prevents Hooks coupling universal coupling cross axle axial float, to overlap roller bearing on each spindle nose by cross axle (9), roller bearing outboard bearing overcoat (3), spacer (4) is housed between each spindle nose end face of cross axle (9) and bearing outside (3) interior edge face and forms, it is characterized in that: bearing outside (3) center is provided with to through hole; Cross axle (9) spindle nose end face center is provided with tapped hole (8); The wear-resisting dish spring of the in-built 1-4 part of spacer (4) (5); With the bolt (6) of a band wear-resistant pad (7), through bearing outside (3) through hole, wear-resisting dish spring (5) center, be screwed into cross axle (9) spindle nose tapped hole (8).
