Abstract

The invention discloses a rolling bearing. The rolling bearing comprises an outer ring, an inner ring and a plurality of rolling bodies. The outer ring is provided with an outer rail. The inner ring is arranged on the inner side of the outer ring and provided with an inner rail corresponding to the outer rail. The multiple rolling bodies are contained and arranged between the inner rail and the outer rail. An installation groove is formed in a sunken mode in the end face of the outer ring or the inner ring in the axial direction and is provided with two bevels. The opening width of the installation groove is smaller than the groove bottom width. The installation groove makes a breakage position be formed in the outer rail or the inner rail. A filling part is arranged in the installation groove and provided with matching faces opposite to the bevels. The bevels are matched with the matching faces in a tight fit mode. The filling part is provided with a filling-up rail used for filling up the breakage position.

Description

Rolling bearing

Technical field

The present invention relates to a kind of bearing, particularly relate to the assembling structure of a kind of rolling bearing.

Background technology

Rolling bearing is a kind of bearing arranging roller staggered each other between internal ring and outer shroud, and makes rolling bearing can bear radial load, axial load and moment load simultaneously. Compared with the bearing of general type, rolling bearing is particularly well-suited to the occasion of requirement high rigidity and running accuracy, such as machine tool and mechanical arm etc. Look back existing rolling bearing such as Japanese Unexamined Patent Publication 2008-208971, JP 2011-106544 patent, it is all that the mounting groove for assembling roller is designed to the design parallel with direction of principal axis, and the filling member being used for filling mounting groove in the ideal case should be matched with orbital plane, and orbital plane is allowed to keep smooth. But, produce because mismachining tolerance makes filling member and orbital plane still have irregular situation. If from known rolling bearing, filling member must have the design supplying two orbital planes, easily produce filling member to align with the orbital plane of one of them, and another orbital plane is still irregular situation, namely the irregular chance of orbital plane is high, therefore, often processing repeatedly is contemplated to make orbital plane smooth, but also improves processing cost.

Summary of the invention

It is an object of the invention to provide one can make implant be accurately positioned, and allows the smooth rolling bearing being connected of track and implant.

In order to reach above-mentioned purpose, the solution of the present invention is:

A kind of rolling bearing, comprises: an outer shroud, and it is provided with an outside track; One internal ring, it is located at the inner side of this outer shroud, is provided with the inner orbit of this outside track relatively; Multiple rolling elements, it is located between this inner orbit and outside track; This outer shroud or this internal ring one of them be arranged with a mounting groove in axial end face, this mounting groove has two inclined-planes, makes the A/F of this mounting groove less than slot bottom width, and this mounting groove makes this outside track or inner orbit, and one of them produces a breakage; One filling member is located at this mounting groove, and this filling member has the mating surface on relatively this inclined-plane, snugly coordinates between this inclined-plane with mating surface, this filling member have fill up this breakage fill up track; Being provided with a shrinkage pool in this mounting groove, this filling member is provided with the screw hole of this shrinkage pool relative; One screw and this screw hole contact at the bottom of this shrinkage pool after screwing togather.

The angle on described inclined-plane is 2 to 33 degree.

After adopting said structure, rolling bearing of the present invention has the design on two inclined-planes by mounting groove, the mating surface making filling member is able to coordinate with this inclined-plane, and limit the direction of principal axis degree of freedom of this filling member, and the degree of freedom in direction, footpath is to position by the locking of this screw, thereby reach the effect of multi-direction location, and the present invention is because of the collocation by this inclined-plane Yu mating surface, therefore the position, direction, footpath of this filling member can be finely tuned, make this fill up track and be able to be connected smooth with this outside track or inner orbit and then the problem solving prior art. The mounting groove of rolling bearing of the present invention and the structure of filling member, can reach, by geometrical relationship, the effect that filling member is accurately positioned, and allows track and filling member are smooth to be connected.

Detailed description of the invention

In order to technical scheme is explained further, below by specific embodiment, the present invention will be described in detail.

Refer to shown in Fig. 1 to Fig. 4, graphic for the present invention the first preferred embodiment, one rolling bearing of the present invention, comprise: an outer shroud 1, it is provided with an outside track 11; One internal ring 2, it is located at the inner side of this outer shroud 1, and is provided with the inner orbit 21 of this outside track 11 relatively; Multiple rolling elements 5, it is located between this inner orbit 21 and outside track 11; This internal ring 2 is arranged with a mounting groove 22 in the end face of direction of principal axis X, and this mounting groove 22 has two inclined-planes 24, makes the A/F T of this mounting groove 22 less than slot bottom width D, and this mounting groove 22 makes this inner orbit 21 produce a breakage 25; One filling member 3 is located at this mounting groove 22, and this filling member 3 has the mating surface 33 on relatively this inclined-plane 24, snugly coordinates between this inclined-plane 24 with mating surface 33, this filling member 3 have fill up this breakage 25 fill up track 32; Being provided with a shrinkage pool 23 in this mounting groove 22, this filling member 3 is provided with the screw hole 31 of this shrinkage pool 23 relative; One screw 4 contacts at the bottom of this shrinkage pool 23 after screwing togather with this screw hole 31; In order to make the processing of this mounting groove 22 more convenient and there is the effect of direction of principal axis X position positioning this filling member 3, advise that the angle Q on this inclined-plane 24 is 2 degree to 33 degree, and define 2 degree and be above because the difficulty of this mounting groove 22 of processing can be made to increase less than 2 degree, man-hours requirement need to extend and yield is not high, and define less than 33 degree and be primarily due to when angle is more than 33 degree, this mounting groove 22 has significantly stress to be increased, it is easy to be deformed.

Refer to shown in Fig. 5 to Fig. 8, the present invention the second preferred embodiment graphic, the present embodiment is different from first embodiment to be in that: this mounting groove is arranged at this outer shroud 1, and this mounting groove 12 has two inclined-planes 14 identical with first embodiment, make the A/F T of this mounting groove 12 less than slot bottom width D, much more no longer this mounting groove 12 makes this outside track 11 produce a breakage 15, and all the other structures, configuration and effect are all identical with the first preferred embodiment, to repeat at this.

The product form of above-described embodiment and the graphic and non-limiting present invention and style, any person of an ordinary skill in the technical field is to its suitably change done or modifies, and all should be regarded as the patent category without departing from the present invention.
