Description

A kind of roller chiasma type bearing

Technical field

The utility model is related to a kind of bearing, more particularly to a kind of roller chiasma type bearing.

Background technology

Bearing on bearing under prior art, the especially joint of industrial robot six precision planetary reducer, it mostly is series of rows Star gear train, deceleration transmission is carried out between multigroup gear by intermeshing tooth, this tooth engagement system defective tightness, so Substantial amounts of abrasion can be caused, causes load-carrying ability to decline, can also shorten the service life of gear train.

Utility model content

In order to solve problem of the prior art, the utility model provides a kind of roller chiasma type bearing, and it adopts staggered form roller Structure, can effectively fit bearing inner race and outer ring, accomplish that inner ring can bear with outer ring without vibration gap, and inner ring and outer ring Big load, and farthest saved the use space for installing bearing.

The technical scheme that the utility model is adopted is as follows：

A kind of roller chiasma type bearing, including bearing inner race and bearing outer ring, pass through retainer between bearing inner race and bearing outer ring One circle roller is installed, adjacent roller is arranged in a crossed manner, the face of cylinder of the roller carries respectively described bearing inner race and bearing Outer ring.

Helical teeth is provided with bearing inner race inwall.

Plugging hole is provided with bearing outer ring, blocking is provided with described plugging hole, described blocking passes through elastic cylinder lock Tightly.

The beneficial effect brought of technical scheme that the utility model is provided is：

A kind of roller chiasma type bearing of the present utility model, it does not have single bearing outer ring and inner ring, and bearing outer ring and inner ring are straight Connect design on workpiece, so as to ensure that the cooperation between workpiece and workpiece, it is ensured that workpiece can bear more high pulling torque, axially Without vibration gap, and the space that installation bearing is used effectively is saved.

Description of the drawings

Technical scheme in order to be illustrated more clearly that the utility model embodiment, below will be to using needed for embodiment description Accompanying drawing be briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present utility model, right For those of ordinary skill in the art, on the premise of not paying creative work, can be obtaining other according to these accompanying drawings Accompanying drawing.

Fig. 1 is a kind of bearing inner race and roller construction schematic diagram of roller chiasma type bearing of the present utility model；

Fig. 2 is a kind of internal structure sectional view of roller chiasma type bearing of the present utility model.

Specific embodiment

To make the purpose of this utility model, technical scheme and advantage clearer, the utility model is implemented below in conjunction with accompanying drawing Mode is described in further detail.

Embodiment one

As shown in accompanying drawing 1,2, a kind of roller chiasma type bearing, including bearing inner race 1 and bearing outer ring 2, the He of bearing inner race 1 A circle roller 4 is provided with by retainer 3 between bearing outer ring 2, adjacent roller 4 is arranged in a crossed manner, the circle of the roller 4 Cylinder carries respectively described bearing inner race 1 and bearing outer ring 2.

As shown in Figure 2, it is provided with helical teeth 5 on the inwall of bearing inner race 11.

Plugging hole 6 is provided with bearing outer ring 2, blocking 7 is provided with described plugging hole 6, described blocking 7 is by elasticity Straight pin 8 is locked.

During installation, first bearing outer ring 2 and bearing inner race 1 are fixed with special tooling, but inner ring 1 and outer ring 2 can rotate, will The plugging hole 6 of outer ring 2 upward, roller 4 is put in inner ring raceway with specific purpose tool by plugging hole 6, further according to roller 4 Retainer 3 is inserted in direction by plugging hole 6, then passes through plugging hole 6 by roller 4 with specific purpose tool further according to the direction of retainer 3 In being put into inner ring raceway, retainer, roller ... are sequentially placed into, the rotary inner ring in assembling process, until roller, retainer In filling up whole circle raceway, insertion blocking 7 is fixed on blocking on outer ring with elastic cylindrical pin 8.The outer diameter tolerance control of roller In the range of 0.003, roughness is controlled within Ra0.2, and the raceway rod of inner ring and outer ring is coarse away from controlling within 0.02 Degree control is within Ra0.8.

Preferred embodiment of the present utility model is the foregoing is only, it is all of the present utility model not to limit the utility model Within spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in protection domain of the present utility model Within.
