The highi degree of accuracy that generally adopt the home and abroad axially-radial combination bearing adopts the cylindrical roller combination more, radially adopts one group of cylindrical roller combination, axial carrying adopts the combination of bidirectional propulsion cylindrical roller.This structure can bear certain axially, radial load, but on the high speed performance because the influence of roller centrifugal force in operation process can produce certain slip, thereby influence the overall performance of bearing.And a kind of radial roller of the utility model and end thrust tapered roller combination bearing, because thrust cone roller rolling bus and raceway bus all intersect on the shaft axis of bearing certain a bit, therefore, rolling surface can form pure rolling, limit speed and be higher than cylindrical roller thrust bearing far away, thereby and, rolling surface reduced slip because of forming pure rolling, when bearing is worked under fast state roller contact with raceway more stable, the working life of having improved bearing.
The beneficial effects of the utility model are:
1, the utility model adopts unique texture, and the end thrust roller designs become tapered roller, the end thrust raceway is designed to the tapered raceway face, thereby realized the axial cylindrical-radial thrust circular cone combination bearing of entire combination, have the advantages that to unite carrying, high rigidity, highi degree of accuracy and high limit rotating speed, the end face run-out of this combination bearing and circular runout can reach the precision of um level.Limit speed is enhanced about more than once than same specification radial-axial cylindrical roller combination bearing.So field that can be widely used in the demand highi degree of accuracy, run up.
2, the utility model structurally since on the rolling bus of thrust cone roller and the shaft axis that the raceway bus all intersects at bearing certain a bit, therefore, rolling surface can form pure rolling, limit speed and be higher than cylindrical roller thrust bearing far away, and guaranteed that product has reduced sliding friction in heavy duty work, improved the working life of bearing.
3, owing to its premium properties, this product can be widely used in precision rotating platform and high-precision applications occasions such as other precision type instrument, machine spindle, also can be applicable to axially-radially all be subjected to can improve the time between failures of equipment on the equipment of big load.
4, the utility model is in processing and manufacture process, and the logarithmic curve form is all adopted in contacting between circular cone raceway and roller, has guaranteed the maximum contact face of combination bearing when bearing capacity, thereby has improved the bearing capacity of product.
