Problems solved by technology

[0005] In the prior art, the rollers are fixedly installed on the corresponding integrally formed fitting parts, which can only realize the basic function of converting sliding friction into rolling friction. For the different usage conditions of the transmission mechanism, the force of the rollers, The choice of rolling groove structure and the variability of rolling groove processing methods are not involved, so it cannot be applied to the selection of transmission devices under various working conditions, and there is a problem of insufficient application flexibility

Embodiment Construction

[0039] A detailed description will be given below in conjunction with the accompanying drawings.

[0040] The invention provides a worm gear with spherical rollers and its transmission mechanism, such as figure 1 , 3 , 4, 5, it includes at least a worm 300, a worm wheel 100 and a roller 200. Several rollers 200 are arranged at intervals along the circular path on the circumferential surface of the worm wheel 100 . At least a part of the rollers 200 is exposed outside the body of the worm wheel 100 , and the exposed part contacts the engagement portion 310 provided on the worm 300 . The rotation axis of the worm 300 is perpendicular to and not coplanar with the rotation axis of the worm wheel 100. Therefore, driven by an external motor, the worm 300 rotates along its axis, and then the meshing part 310 arranged on it drives the roller 200 to rotate by sliding friction. The moving direction of the helical path formed by the engaging part 310 moves, and thereby drives the worm ...

Abstract

The invention discloses a worm gear with a spherical roller and a transmission mechanism of the worm gear. The worm gear at least comprises a worm gear body having at least a rotation axis and capable of rotating around the axis, the worm gear body is provided with a plurality of rolling grooves along a circumferential surface, rollers being mounted in the rolling grooves, the rolling grooves limiting the rollers in a manner that split parts enclose each other, namely, the hemispherical portion, facing the worm gear body, of the roller protrudes out of the rolling grooves, so that the intersection position of the round rolling line, rolling in the rolling grooves, of the roller and the first rolling groove edge and the second rolling groove edge of the rolling groove used for surrounding the roller is located outside the force line, applying force to the roller, of the worm. The plane, where the first rolling groove edge and the second rolling groove edge are located, of the roller is not orthogonal to the force line where the worm exerts pressing acting force on the roller.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a worm wheel with spherical rollers and a transmission mechanism thereof. Background technique [0002] The most common form of transmission or reducer device in the mechanical field is the worm gear transmission, which has been widely used in mining machines, oil production, chemical plants, infrastructure, heavy and light industries, military industry, bionic robots, aerospace and other fields. The existing worm gear transmission mechanism has a relatively large single-stage transmission ratio, and has relatively high transmission performance compared with ordinary gear-shaped transmission devices, and has the advantages of self-locking and stable transmission. The existing worm wheel and worm usually adopt the way of sliding friction to transmit force, so that there is a large wear between the worm wheel and the worm, which is not conducive to the life management require...
