The utility model comprises a seat body, wherein a cambered surface, a side, a fixed surface, an inner bore and a fixed device used for installing a fixed bearing seat are respectively arranged on the seat body, and a joint face between a circular arc face and the side is a bevel. The utility model is convenient to connect with an external connection bearing through the inner bore, and the fixed device can be a screw hole, a bolt component or other mechanical devices for fixed connection, and can also be a weld mode or other fixed connection modes. The bearing seat has the characteristics of compact structure, high strength and reasonable structural arrangement.
Description
Technical field
The utility model relates to a kind of bearing support, particularly is applicable to the structure improvement of the bearing support in the universal joint.
Background technique
Liu Tong bearing support generally is made up of a pedestal and a bearing attachment hole in the market, bearing attachment hole in this kind bearing support is located on the pedestal, and there is angle between the outer wall side of bearing attachment hole and the pedestal, such Placement adds a large amount of cutting material of needs in man-hour, and be easy on the pedestal in the local of joint produce concentrating of stress, cause the bulk strength of bearing support to reduce.
Summary of the invention
The utility model has mainly solved in the prior art existing structure and has owed compact, and it is high that intensity is owed, and structural configuration is very rational technical problem, and a kind of reasonable in design is provided, compact structure, and intensity is higher, the universal joint shaft bearing of reasonable structural arrangement.
It is not too convenient that the utility model has also solved in the prior art existing processing simultaneously, and the big stress of bite is easy to the technical problem concentrated, provides a kind of processing comparatively convenient, and bite is less, and stress distribution is the universal joint shaft bearing comparatively reasonably.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: this kind universal joint shaft bearing, comprise pedestal, be respectively arranged with cambered surface, side, stationary plane and endoporus on the described pedestal, also be provided with the fixing device that is used to install and fix bearing support on the pedestal, be characterized in that the junction surface between described arc surface and the side is the inclined-plane.Being connected with external bearing by endoporus is convenient, it should be noted that herein fixing device can be screw hole, bolt assembly, also can be that other is used for fixing the connection mechanical device, can also be fixedly connected modes such as a kind of welding.
As preferably, inclined-plane one end and described arc surface on the described pedestal are tangent, being connected of its other end with the side, and the angle of inclined-plane and stationary plane is 30 degree-45 degree.And in this angular range, best results.
As preferably, the centre of described pedestal bottom can be provided with a boss.Like this, favourable raising bulk strength, the structural strength that makes it the endoporus bottom is able to reinforcement, and it is more reasonable to arrange.
As preferably, described endoporus can be blind hole.
As preferably, described fixing device can be a tapped hole.
As preferably, the height of the described tapped hole degree of depth and side is close.
As preferably, a side of described pedestal can be arcuation.
As preferably, vertical profile of the side on the described pedestal, inclined-plane, cambered surface is arc shaped.
The utility model compared with prior art has following beneficial effect: structural design is more reasonable, the cambered surface at pedestal top is connected with an inclined-plane with the side of both sides, there is angle between the outer wall side of replacement prior art middle (center) bearing attachment hole and the pedestal, avoided bearing support to need the drawback of a large amount of cutting materials in course of working, processing technology is advantages of simple more; Also avoid simultaneously bearing support concentrated at this place output stress, caused reducing the intensity of bearing support; The overall structure of whole bearing support is compact more.In addition, also be provided with a boss, thickened the pedestal thickness between endoporus and the bearing support, realize strengthening the intensity of bearing support by bottom at bearing support.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, pedestal 1 is provided with the endoporus 6 that is used to install connection bearing in the present embodiment, and the termination of the size of endoporus 6 and shape and external bearing is complementary; The bottom surface of pedestal 1 is provided with to fix supports the stationary plane 4 of usefulness, and stationary plane 4 is connected with the side 3 that is positioned at pedestal 1 both sides respectively; The top of pedestal 1 is provided with a cambered surface 7; Inclined-plane 2 is between cambered surface 7 and side 3, the one end is connected with side 3, the other end on inclined-plane 2 and cambered surface 7 are tangent, have realized smooth connection between cambered surface 7 and the side 2 by inclined-plane 2, and in the present embodiment inclined-plane 2 and stationary plane 4 between angle be 40 degree.By inclined-plane 3 is set, make the overall structure of bearing support compare with bearing support of the prior art, it is reasonable that general structure is more compact, intensity is higher, overall structural arrangement more becomes.
Bottom at pedestal 1 also is provided with the fixing device I that is used for fixing the installation shaft bearing, and fixing device I is the tapped hole 5 that is arranged on two ends on the stationary plane 4 in the present embodiment, and tapped hole 5 can be a blind hole, and the height of tapped hole 5 degree of depth and side 2 is close.Centre in the bottom of pedestal 1 also is provided with boss 8, by boss 8 is set, has thickeied the thickness of the pedestal 1 of endoporus 6 bottoms, has strengthened the bulk strength of pedestal 1.
Both can be the face that symmetry exists the inclined-plane 2 of pedestal 1 both sides in the present embodiment and side 3.
As shown in Figure 2, the endoporus 6 of the connection bearing that is used in the present embodiment is blind hole.And vertical profile on the cambered surface on the pedestal 17, side 3, inclined-plane 2 is an arc shaped.
As shown in Figure 3, a side of pedestal is for being an arc surfaced.
When present embodiment is installed, only need endoporus 6 on the pedestal 1 is connected with the termination of bearing, fixing by the tapped blind hole at two ends, pedestal 1 bottom simultaneously, can realize that bearing rotates on pedestal 1.
In addition, the utility model structure is confined to above-mentioned specific embodiment with being connected to have more than, the conversion or the connection that also exist following structure are equal to alternative: can be arbitrarily angled between 30 degree-45 degree such as the angle of inclined-plane 2 and stationary plane 4, endoporus 6 also can be a through hole; Fixing device I also can be other and is used for fixing the connection mechanical part, and is such as bolt etc., this for the conspicuous variation of those of ordinary skills or be equal to replacement and all should belong to protection domain of the present utility model.
