Abstract
The invention discloses a bearing structure. The bearing structure comprises an outer bearing ring, balls and an inner bearing ring, wherein the balls are mounted between the outer bearing ring and the inner bearing ring, the outer bearing ring is provided with oil grooves which are arranged in the outer bearing ring and have top openings, the interior of the inner bearing ring is provided with two raceways which are correspondingly arranged on the inner bearing ring, shaft holes are arranged above the raceways and formed in the inner bearing ring, shafts are arranged in the shaft holes, and the shafts are connected with the shaft holes through pins; and the bearing structure further comprises support strips arranged on the inner bearing ring, wherein the support strips are provided with humps which are trapezoid and successively connected, and a groove with a downward opening is formed between every two humps. The bearing structure can directly reduce a friction surface between the shafts and the inner walls of the shaft holes, effectively reduces friction coefficients between the shafts and the shaft holes, abates noise, facilitates installation and dismounting of a bearing, realizes reliable connection and effectively guarantees the rotation performance of the bearing, thereby prolonging the service life of the bearing.
Description
Technical field
The present invention relates to a kind of mechanical part, particularly a kind of bearing structure.
Background technique
Bearing is the supporting member in mechanical transmission mechanism, and for determining running shaft and other part relative movement positions, its quality and bearing capacity directly affect the service behaviour of mechanical complete machine, and the running drive miscellaneous part by bearing moves.Common high speed light loading bearing load is low, high speed rotating for the ease of bearing, conventionally the fit tolerance of bearing outer ring and bearing support is less, therefore often there is in use for some time skidding, seriously reduced transmission performance, and also cannot better be guaranteed working life, be greatly reduced the reliability of bearing working.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, a kind of rubbing surface that can directly reduce axle and shaft hole inner wall is provided, can effectively reduce the friction factor between axle and axis hole, reduce the bearing structure of noise.
To achieve these goals, the technical solution used in the present invention is such: bearing structure of the present invention, comprise bearing outer ring, ball and bearing inner race, ball is contained between bearing outer ring and bearing inner race, on bearing outer ring, have oil groove, oil groove is all arranged on bearing outer ring inside, and open top, bearing inner race inside is provided with raceway, raceway is two, and correspondence is arranged on bearing inner race, raceway top is provided with axis hole, axis hole is opened on bearing inner race, in axis hole, be provided with axle, between axle and axis hole, by bearing pin, be connected, also comprise the supporting bar being arranged on bearing inner race, on supporting bar, be equipped with projection, it is trapezoidal that projection is, projection connects successively, and form downward opening groove between two adjacent protrusion.
Further, as a kind of concrete structural type, supporting bar of the present invention two ends are provided with fixed block.
Further, as a kind of concrete structural type, bearing inner race of the present invention outside is provided with screw thread.
Further, as a kind of concrete structural type, the curvature of raceway of the present invention is 23-24 millimeter.
Further, as a kind of concrete structural type, the offset of raceway of the present invention is 0.6-0.7 millimeter.
Compared with prior art, the invention has the advantages that: the present invention can directly reduce the rubbing surface of axle and shaft hole inner wall, can effectively reduce the friction factor between axle and axis hole, reduce noise, and facilitate bearing installation and removal, connect reliably, can effectively guarantee the rotating property of bearing, thereby improve bearing working life.
