Compact worm rotation device

Abstract

The invention discloses a compact worm rotation device, which comprises a rotation shell and a worm shell communicating with the rotation shell. A spiroid gear is arranged in the rotation shell; a spiroid worm mechanism is arranged in the worm shell, and comprises a spiroid worm extending from the worm shell into the rotation shell, and a multi-stage planetary mechanism arranged on the bottom part of the spiroid worm. During the operation process, an input shaft rotates to drive a sun wheel on the bottommost part to rotate, each sun wheel rotates to drive each planet wheel to circumferentially rotate around an axle of each sun wheel at the same time so as to drive each planet carrier to rotate through a planet wheel axle and further drive an adjacent upper sun wheel to rotate, finally, the rotation is transmitted to the spiroid worm through the planet carrier on the topmost part, and the spiroid worm drives the spiroid gear to realize rotation. Compared with the prior art, the worm rotation device provided by the invention has the advantages of compact structure, high reliability, and lower maintenance cost.

Description

technical field [0001] The invention relates to the mechanical field of reducers, in particular to a compact worm turning device. Background technique [0002] The worm rotary device is widely used in metallurgy, port machinery, oil drilling platform, military industry, medical treatment, solar power generation and other industries. Its utilization and development potential is huge, but no matter what industry or working condition, its products have high Rotational accuracy and low cost are the keys to the core competitiveness of products. At present, the worm pairs used in mainstream slewing devices are mainly cylindrical worm and toroidal worm drive, so they have the following disadvantages and deficiencies: (1) The material of worm gears is often bronze alloy, which will inevitably consume a large amount of non-ferrous metals in the mass production of slewing drives, and improve the Cost; (2) Copper alloy is easy to wear during operation, and the backlash of the worm pai...

At present, the worm pairs used in mainstream slewing devices are mainly cylindrical worm and toroidal worm drive, so they have the following disadvantages and deficiencies: (1) The material of worm gears is often bronze alloy, which will inevitably consume a large amount of non-ferrous metals in the mass production of slewing drives, and improve the Cost; (2) Copper alloy is easy to wear during operation, and the backlash of the worm pair increases, which reduces the operating accuracy of the product and increases the cost of operation and maintenance and product replacement; (3), the strength of the copper alloy is insufficient, and the product is bound to increase under the same strength Weight size, increase cost
