Description
Technical field
This utility model belongs to lubrication technical field of bearings, is specifically related to a kind of novel roller screw anti-friction bearing。
Background technology
Ball screw assembly, is that gyration is converted into rectilinear motion, or by desirable product that transform linear motion is gyration。Ball screw assembly, is made up of screw rod, nut, reversing device and ball, and the function of ball screw assembly, is the motion that is in line by convert rotational motion, or torque axis changes into axial repetitiousness active force, has high accuracy, reversibility and high efficiency feature concurrently simultaneously。Ball screw assembly, has the features such as high accuracy, reversibility and high efficiency, and this is extending further and development of trapezoidal screw, and trapezoidal screw sliding action is become scroll actions by the significance of this development exactly。Owing to having only small frictional resistance, ball-screw bearing is widely used in various industrial equipment and precision instrument。When present ball-screw moves to the abrasion of screw thread quite seriously, the great minimizing of leading screw life-span, add production cost, be badly in need of wanting a kind of new pattern rolling ball leading screw anti-friction bearing eliminate these shortcomings。
Utility model content
The purpose of this utility model is that provides a kind of novel roller screw anti-friction bearing to solve the problems referred to above。
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of novel roller screw anti-friction bearing, including ball-screw, bearing outside collar, retainer, sliding ball, whole device is arranged on described ball-screw, described ball-screw surface configuration has external screw thread, described ball-screw two ends are provided with screw thread polished end, described ball-screw is assemblied in bearing inner race, described bearing inner race inner surface is provided with screw thread inner ring, described sliding ball is installed in the thread gaps that described screw thread inner ring contacts with described ball-screw, described bearing inner race outer surface is provided with retainer, described retainer outer surface is provided with circular groove, inside is each equipped with ball body, described ball body upper surface is at described bearing outside collar inner surface, described bearing outside collar upper and lower side is provided with oil-in。
In said structure, the sliding on described ball-screw of whole bearing arrangement, described bearing outside collar can support external connection object, ensure that it is normally mobile and rotates, described bearing inner race and described ball-screw threaded engagement, centre is provided with described sliding ball and makes the movement on leading screw of the bearing installation material more smooth, reduces abrasion。
In order to improve ball-screw bearing effect further, described bearing inner race inner surface is provided with screw thread inner ring, is provided with described sliding ball with described ball-screw in the thread gaps that described screw thread inner ring contacts。
In order to improve ball-screw bearing effect further, described bearing inner race outer surface is provided with retainer, and described retainer outer surface is provided with circular groove, and inside is each equipped with ball body。
In order to improve ball-screw bearing effect further, described ball body upper surface is at described bearing outside collar inner surface, and described bearing outside collar upper and lower side is provided with oil-in。
Have the beneficial effects that: adopting bearing inner race to be threaded inner ring and coordinate with threaded screw rod, add that the sliding of mounted inside is rolled so that plant running sliding is more smooth, ball-screw is greatly prolonged service life。
