Abstract

The utility model relates to a driven roller end face worm wheel in plane is vice belongs to mechanical transmission's application, is used for transmitting motion and power between the alternating axis. Its characterized in that: worm and the meshing of the driven roller in plane, the plane rolling element is by driven roller, antifriction bearing, axle and circlip constitute, driven roller passes through antifriction bearing and links to each other with the axle, replace traditional worm -gear toothing with driven roller, and driven roller can be around the axle rotation of plane rolling element, become rolling friction with traditional sliding friction like this, thereby the not enough of traditional terminal surface worm wheel has been solved, and this transmission is vice have efficient, calorific capacity is few, advantages such as difficult veneer, any wide application prospect has.

Description

A kind of plane roller follower face worm gear drive

Technical field

The utility model belongs to mechanically operated application, relates to a kind of plane roller follower face worm gear drive, is used for transmitting the force and motion between alternating axis.

Background technique

Tradition end face worm-gear drive pair, contact between worm tooth-surface and the worm gear flank of tooth is linear contact lay mode, friction between these transmissions is rolling friction, thus cause heating value to be glued together greatly, easily, and the antifriction material that worm gear teeth generally needs costly, manufacture cost is high, and efficiency is relatively low.Therefore, it is possible to produce, a kind of efficiency is high, cost is low, and greasy property worm gear pair tool that is good, that rub little is of great significance.

Summary of the invention

1, the technical problem that the utility model solves is: the deficiency overcoming traditional worm gear pair, proposes a kind of plane roller follower face worm gear drive, this kind of worm gear pair not only greasy property good, rub little, and centre distance is little, compact structure, is convenient to produce.

2, the utility model solves the technological scheme that its technical problem adopts and is: a kind of plane roller follower face worm gear drive, the worm screw (1) comprising worm gear (2) and be meshed with it, worm gear (2) is made up of two half worm gears, be respectively half worm gear (21) and lower half worm gear (22), and upper half worm gear (21) and lower half worm gear (22) are fixed together by bolt (8).The end face of worm gear (2) is evenly distributed with some plane rolling bodies (3), plane rolling body (3) is made up of roller follower (4), rolling bearing (5), axle (6) and circlip (7), roller follower (4) is connected with axle (6) by rolling bearing (5), solves the deficiency of traditional face worm gear drive with this.

3, described roller follower (4) can revolve round the sun around worm gear (2), also can around the axis autobiography of the axle of plane rolling body (3) (6).

4, the roller follower (4) of traditional worm gear pair gear teeth plane rolling body (3) is replaced, thus traditional sliding friction is become rolling friction.

5, remarkable result of the present utility model is: after worm gear teeth adopts roller follower (4) to replace, the sliding friction of traditional face worm gear drive is become rolling friction, not only reduce friction, reduce my spoke heating value at movement process, not easily glue together, improve efficiency, low cost of manufacture, improve greasy property and the contact performance of traditional face worm gear drive simultaneously.

Accompanying drawing explanation

Fig. 1 is the mesh schematic representation of a kind of plane roller follower of the utility model face worm gear drive;

Fig. 2 is the plane rolling body distribution map of a kind of plane roller follower of the utility model face worm gear drive;

Fig. 3 is the plane rolling body sectional view of a kind of plane roller follower of the utility model face worm gear drive.

Embodiment

Below by reference to the accompanying drawings, and reach required function requirement in conjunction with plane roller follower face worm gear drive, the utility model is further described: the worm screw (1) that a kind of plane roller follower face worm gear drive comprises worm gear (2) and is meshed with it, worm gear (2) is made up of two half worm gears, be respectively half worm gear (21) and lower half worm gear (22), and upper half worm gear (21) and lower half worm gear (22) are fixed together by bolt (8).The end face of worm gear (2) is evenly distributed with some plane rolling bodies (3), plane rolling body (3) is made up of roller follower (4), rolling bearing (5), axle (6) and circlip (7).

When worm screw (1) is rotated, worm screw (1) inside contact surface contacts with the roller follower (4) on worm gear (2), extrudes and produce power, and then promotes worm gear (2) rotation, realizes the rotation of worm gear (2) and worm screw (1) with this.

Claims

1. a plane roller follower face worm gear drive, the worm screw (1) comprising worm gear (2) and be meshed with it, it is characterized in that: worm gear (2) is made up of two half worm gears, be respectively half worm gear (21) and lower half worm gear (22), and upper half worm gear (21) and lower half worm gear (22) are fixed together by bolt (8), the end face of worm gear (2) is evenly distributed with some plane rolling bodies (3), plane rolling body (3) is by roller follower (4), rolling bearing (5), axle (6) and circlip (7) composition, roller follower (4) is connected with axle (6) by rolling bearing (5).
