Description
Technical field
The utility model relates to a kind of improved type bearing means.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Rolling bearing when rotated, rely on the rotation of rolling element, inner ring is rotated, the smooth degree direct influence of the rolling element rotation efficiency of inner ring in the inside of outer ring, rolling element of the prior art adopts retainer to be fixed, retainer of the prior art is a simple fixation, to keep the gap between each rolling element, avoid rolling element generation entanglement, rolling element when rotated, and rub between retainer, reduce the rotation efficiency of rolling element.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of improved type bearing means, retainer in this device and between rolling element, there is less surface friction drag, when inner ring rotates, reduce the friction factor between inner ring and outer ring, the rotation efficiency that improve inner ring of indirect.
For solving the problem, the utility model adopts following technological scheme:
A kind of improved type bearing means, comprise inner ring, outer ring, rolling element and retainer, it is inner that described inner ring is arranged on described outer ring, described inner ring and described outer ring are coaxially arranged, described rolling element is connected between described inner ring and outer ring, described rolling element annular is provided with more than five, described retainer connects described rolling element according to this, described retainer is annular, on described retainer, annular is provided with the positioning ring of several positioning rolling bodies, the inside of described positioning ring is provided with positioning hole, the point of contact of more than three is provided with in the hole wall position of described positioning hole annular, described point of contact is hemisphere, described point of contact contacts with described rolling element, the inside of described inner ring has the mounting hole of a locating transmission axle, the hole wall position of described mounting hole is provided with keyway.
As preferred technological scheme, on the front-end face of described outer ring, annular is provided with the fixed hole of more than three, the front-end face of described outer ring is provided with a dust-proof cover, is combined with screw between dust-proof cover and described fixed hole.
As preferred technological scheme, the outer ledge position circular arc of described outer ring has the chamfering of a C1.5mm-C2mm.
As preferred technological scheme, the outer surface of described rolling element has texturizing layer.
The beneficial effects of the utility model are: the retainer in this device and have less surface friction drag between rolling element, when inner ring rotates, reduce the friction factor between inner ring and outer ring, the rotation efficiency that improve inner ring of indirect, the structure of this device is simple, manufacture and install more for convenience, cost is comparatively cheap, is applicable to promoting the use of.
