Abstract
The utility model discloses a primary planet gear which comprises a gear disc. A plurality of rectangular gear teeth are arranged at the peripheral edge surrounding the gear disc, two side surfaces of each rectangular gear tooth are outwardly protruded arc-shaped surfaces, and a tooth top and the two side surfaces of each rectangular gear tooth are respectively provided with abrasion-resistant layers. A shaft hole is arranged in the middle of the gear disc, annular grooves are respectively arranged at two ends of the inner wall of the shaft hole, and sealing rings are arranged in the annular grooves. The primary planet gear has the advantages that the primary planet gear is compact in structure, the abrasion-resistant layers are arranged on surfaces of the gear teeth, and the two side surfaces of each gear tooth are the outwardly protruded arc-shaped surfaces, so that the abrasion-resistant performance of the planet gear is improved, and noise is reduced; and the annular grooves provided with the sealing rings are respectively arranged at the two ends of the inner wall of the shaft hole, so that the sealing performance of the planet gear is improved, and the service life of the planet gear is prolonged.
Description
Technical field
The utility model relates to field of gears, specifically a kind of one-level planet wheel.
Background technique
In the course of the work, the rotating speed of planet wheel is very high, owing to have the gap between the section of planet wheel and the sliding bearing, in high-revolving situation, the axial float of planet wheel is larger, produces easily vibration noise, and wearing and tearing are larger, affects the working life of planet wheel.Along with the raising of machining accuracy, its processing technology requires higher, and then has improved processing cost.
The model utility content
The purpose of this utility model provides a kind of one-level planet wheel, and the surface of its gear teeth has wearing layer, and the bi-side of the gear teeth are outwards outstanding arc shaped surface, to improve the wear-resisting property of planet wheel; And the two ends of shaft hole inner wall are respectively equipped with annular groove and are provided with seal ring, to improve the sealability of planet wheel.
The technical solution of the utility model is as follows:
The one-level planet wheel includes wheel disc, centers on the surrounding of wheel disc along having a plurality of rectangle gear teeth, and it is characterized in that: the bi-side of described a plurality of rectangle gear teeth are outwards outstanding arc shaped surface, and the crown of a plurality of rectangle gear teeth and bi-side have respectively wearing layer; The middle part of described wheel disc is provided with axis hole, and the two ends of shaft hole inner wall are respectively equipped with annular groove, is provided with seal ring in the described annular groove.
Described one-level planet wheel is characterized in that: have output shaft pass described axis hole and with the axis hole interference fit.
The beneficial effects of the utility model:
The utility model compact structure, the surface of its gear teeth has wearing layer, and the bi-side of the gear teeth are outwards outstanding arc shaped surface, has improved the wear-resisting property of planet wheel, has reduced noise; And the two ends of shaft hole inner wall are respectively equipped with annular groove and are provided with seal ring, have improved the sealability of planet wheel, have prolonged the working life of planet wheel.
