Description
Technical field
This utility model relates to technical field of engineering machinery, especially a kind of track crane dolly horizontal roller support means.
Background technology
The stationarity of track crane trolley travelling uses impact very big for complete machine, and dolly horizontal wheels of the prior art is passed through
Single bearing is carried out, its poor stability, easily cause the lateral beat of horizontal wheels, and time length causes serious wear, horizontal wheels
Damaging, often run jiggly phenomenon during use, functional reliability is poor.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that a kind of track crane dolly horizontal roller supports dress
Put, thus improve track crane dolly.
The technical scheme that this utility model is used is as follows:
A kind of track crane dolly horizontal roller support means, including rotating shaft, one end of described rotating shaft is provided with axle ring, described
Being provided with support in rotating shaft, the shaft head being positioned at axle Huan Chu front end is provided with horizontal roller by duplex bearing, described axle ring
Outer face is provided with groove, and the inner face of described horizontal roller is provided with projection, and described projection snaps in groove, described tupelo
Outer face, portion is provided with bearing (ball) cover, and described bearing (ball) cover is locked by securing member；The head outer face of described rotating shaft is also installed
Having capping, the outer circumference surface of described capping is locked with horizontal roller by multiple bolts；Also include slide rail, described slide rail and level
Roller cooperating.
Its further technical scheme is:
Described duplex bearing uses angular contact ball bearing.
The beneficial effects of the utility model are as follows:
This utility model compact conformation, rationally, easy to operate, optimize design, use duplex bearing to support installation level
Roller, by the effect of duplex bearing, effectively inhibits the phenomenon of horizontal wheels beat, is greatly improved dependability, extends water
The service life of flat wheel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, rotating shaft；2, support；3, axle ring；4, groove；5, duplex bearing；6, horizontal roller；7, capping；8, bolt；9、
Slide rail.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described.
As it is shown in figure 1, the track crane dolly horizontal roller support means of the present embodiment, including rotating shaft 1, one end of rotating shaft 1
Being provided with axle ring 3, rotating shaft 1 is provided with support 2, rotating shaft 1 head being positioned at front end at axle ring 3 is provided with water by duplex bearing 5
Flat roller 6, the outer face of axle ring 3 is provided with groove 4, and the inner face of horizontal roller 6 is provided with projection, and projection snaps in groove 4,
Rotating shaft 1 head outer face is provided with bearing (ball) cover, and bearing (ball) cover is locked by securing member；The head outer face of rotating shaft 1 is also installed
Capping 7, the outer circumference surface of capping 7 is had to be locked with horizontal roller 6 by multiple bolts 8；Also include that slide rail 9, slide rail 9 roll with level
Take turns 6 cooperatings.
Duplex bearing 5 uses angular contact ball bearing.
Horizontal roller 6 uses duplex bearing 5 to be supported installing, and meanwhile, the inner face of horizontal roller 6 is provided with projection, convex
Rise in the groove 4 snapping in axle ring 3, so further increase the installation reliability of horizontal roller 6, effectively inhibit horizontal wheels beat
Phenomenon, be greatly improved dependability, extend the service life of horizontal wheels.
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model is limited
Scope sees claim, within protection domain of the present utility model, can make any type of amendment.
