Problems solved by technology

[0002] During the use of the worm gear reducer, the worm wheel will be subjected to a large impact force, which will be transmitted to the worm, and an axial impact force will be generated on the worm. If the axial impact force is too large, it will easily damage the support bearing of the worm. Affect the performance and life of the reducer

Embodiment Construction

[0009] The present invention will be further described below in conjunction with drawings and embodiments.

[0010] figure 1 As shown, a worm gear reducer for anti-shock includes a box body 1, a worm wheel 2, a worm screw 3, an end cover 4, a cylindrical roller bearing 5, a double-row tapered roller bearing 6, a shaft sleeve 7, a limit retaining ring 8, Buffer plate 9 and spring 10. The worm wheel 2 and the worm 3 meshed with each other are set in the box body 1. Both ends of the worm screw 3 are supported by cylindrical roller bearings 5 ​​and are both connected to the end cover 3 and packaged in the box body 1. The cylindrical roller bearings at the output end of the worm screw 3 and the There are double-row tapered roller bearings 6 between the end covers, and the double-row tapered roller bearings 6 are sleeved on the worm 3 through the bushing 7. Both ends of the bushing 7 are limited by cylindrical roller bearings and stop rings 8 A buffer plate 9 is provided between t...

Abstract

The invention relates to a worm reducer for impact prevention. The worm reducer for impact prevention comprises a worm gear and a worm, wherein the worm gear and the worm are arranged in a box and are meshed with each other, the two ends of the worm are supported by cylindrical roller bearings to penetrate through end covers so as to be packaged in the box, double-row tapered roller bearings are arranged between any end of the worm and the end cover located at the end or between the two ends of the worm and the end covers located at the two ends, the worm is supported by the double-row tapered roller bearings, and a circle of evenly-distributed springs are arranged between two tapered roller bearings of the double-row tapered roller bearings in a press fit mode. Due to the fact that the circle of evenly-distributed springs are additionally arranged between the two tapered roller bearings of the double-row tapered roller bearings supported by the worm, axial impact force transmitted to the worm by the worm gear can be buffered, the performance stability of the worm can be effectively ensured, and the service life of the reducer is prolonged.

Description

technical field [0001] The invention relates to a reducer, in particular to a worm gear reducer for anti-shock. Background technique [0002] During the use of the worm gear reducer, the worm wheel will be subjected to a large impact force, which will be transmitted to the worm, and an axial impact force will be generated on the worm. If the axial impact force is too large, it will easily damage the support bearing of the worm. Affect the performance and life of the reducer. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an anti-impact worm gear reducer with simple structure, which can effectively buffer the axial force generated by worm gear and worm drive, and prolong the overall performance and service life. [0004] The technical solution of the present invention is: a worm gear reducer for anti-shock, including a worm gear and a worm that are arranged in the box and mesh with each ot...
