Abstract
The utility model discloses a first-level planetary wheel structure. The structure comprises a disk, wherein a plurality of rectangular gears are arranged on the periphery of the disk, anti-wearing layers are arranged on tips and two sides of rectangular gears, a shaft hole is arranged in the middle of the disk, annular slots are arranged at positions of the positive and the negative of the disk, which surround the periphery of the shaft hole, annular grooves are arranged at two ends of the inner wall of the shaft hole respectively, and gaskets are arranged in annular grooves. The structure is compact, the anti-wearing layers are arranged on the surface of the gears, the anti-wearing performance is improved, the noise is reduced, annular slots are arranged on the negative and the positive of the disk, the weight of the first-level planetary wheel is reduced, the stability of the drive of the first-level planetary wheel is improved, annular grooves and gaskets are arranged at two ends of the inner wall of the shaft hole, the sealing performance of the first-level planetary wheel is improved, and the service life of the first-level planetary wheel is prolonged.
Description
Technical field
The utility model relates to field of gears, specifically a kind of one-level planetary gear structure.
Background technique
In the course of the work, the rotating speed of planet wheel is very high, owing to having the gap between the section of planet wheel and the sliding bearing, in high-revolving situation, the axial float of planet wheel is larger, easily produce vibration, and wearing and tearing is 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 planetary gear structure, and the surface of its gear teeth has wearing layer, to improve the wear-resisting property of planet wheel; Front and back at wheel disc is respectively equipped with circular groove, alleviates the weight of one-level planet wheel, to improve the stability of one-level planet gear transmission; 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 planetary gear structure 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 crown of described 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 front and back that centers on axis hole wheel disc on every side is respectively equipped with circular groove, and the two ends of described shaft hole inner wall are respectively equipped with annular groove, are provided with seal ring in the described annular groove.
Described one-level planetary gear structure 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, has improved the wear-resisting property of planet wheel, has reduced noise; Front and back at wheel disc is respectively equipped with circular groove, has alleviated the weight of one-level planet wheel, has improved the stability of one-level planet gear transmission; 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 one-level planet wheel, have prolonged the working life of one-level planet wheel.
