Abstract
The utility model relates to a bearing, in particular to a high-precision conical roller bearing. The bearing comprises a ball base face conical roller and a bearing blocking edge, the ball base curvature radius SR of the ball base face conical roller is from 450-550mm, and the bearing blocking edge is provided with an inner blocking face matched with a ball base face of the ball base face conical roller. Compared with an existing like product, the high-precision conical roller bearing greatly improves rotating stability and lubricating performance due to the fact that the ball base curvature radius of the ball base face conical roller and the corresponding bearing blocking edge are optimized.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of high accuracy circular taper roller bearing.
Background technique
Roller is one of important accessory of bearing.The bearing of general precision only need adopt the roller below three grades, and this class bearing is generally to the basal plane of roller less demanding (comprising the requirement of length, shape and roughness); The roller of above (the containing secondary) precision of high-precision bearing normal operation secondary, kind of bearings is had relatively high expectations to the roller basal plane, not only requires the roller basal plane to have certain shape and roughness, but also must reach certain number range.The roller that present high accuracy circular taper roller bearing adopts is generally the ball basal plane tapered roller of the above precision of secondary, the ball basal plane radius of curvature of ball basal plane tapered roller is unsuitable excessive or too small, crossing conference causes the roller basal plane not have the oil film wedge angle, lubricating grease is difficult to enter smoothly raceway and causes lubricated insufficient, the too small contact stress of roller and bearing edge guard that then can cause is concentrated, the roller rotation is not steady, and the bearing premature failure is scrapped.Therefore, the ball basal plane radius of curvature of ball basal plane tapered roller need to be selected in the number range an of the best.
The model utility content
The technical problems to be solved in the utility model is: select the suitable not problem that operation stability is not high or greasy property is relatively poor that causes bearing in order to solve existing high accuracy circular taper roller bearing because of the design of the ball basal plane radius of curvature of its tapered roller, and provide a kind of spherical base surface of tapered roller radius of curvature through optimizing selected high accuracy circular taper roller bearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of high accuracy circular taper roller bearing, include ball basal plane tapered roller and bearing edge guard, the ball basal plane radius of curvature SR of described ball basal plane tapered roller is 450～550mm, and bearing edge guard has the internal retaining surface that the ball basal plane with ball basal plane tapered roller matches.Experiment showed, that the tapered roller of ball basal plane radius of curvature SR in 450～550mm scope is the most favourable for smooth rotation and the lubricity of bearing.
Preferably, the ball basal plane radius of curvature SR of described ball basal plane tapered roller is 500mm.Further experiment proves that when the ball basal plane radius of curvature SR of ball basal plane tapered roller was 500mm, it is best that the smooth rotation of bearing and greasy property reach.
The beneficial effects of the utility model are: this high accuracy circular taper roller bearing is compared with existing like product, has greatly promoted smooth rotation and the greasy property of bearing because of ball basal plane radius of curvature and the corresponding bearing edge guard of having optimized ball basal plane tapered roller.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. ball basal plane tapered roller 2. bearing edge guards
Embodiment
A kind of high accuracy circular taper roller bearing, as shown in Figure 1, it includes ball basal plane tapered roller 1 and bearing edge guard 2, and the ball basal plane radius of curvature SR of ball basal plane tapered roller 1 is 450～550mm, and bearing edge guard 2 has the internal retaining surface that the ball basal plane with ball basal plane tapered roller 1 matches.
The preferred 500mm of ball basal plane radius of curvature SR of ball basal plane tapered roller 1.Experiment showed, that when the ball basal plane radius of curvature SR of ball basal plane tapered roller 1 is 500mm it is best that the smooth rotation of bearing and greasy property reach.
Claims (2)
