Abstract

The utility model discloses a secondary sun gear structure which comprises a gear disc. A plurality of rectangular gear teeth are disposed on the periphery of the gear disc. A tooth groove is arranged between two adjacent rectangular gear teeth. A stepped hole is arranged in the middle of the gear disc. An annular groove is arranged on the inner wall of the stepped hole. Two sides of each rectangular gear tooth are arc-shaped faces protruding outwards. The tooth tips and the two sides of each rectangular gear tooth are provided with wear-resistant layers respectively. A notch is arranged on each tooth tip. A rubber pad is disposed at the bottom of each hear groove. The secondary sun gear structure has the advantages that the secondary sun gear structure is compact; the surfaces of the gear teeth are provided with the wear-resistant layers, two sides of each gear teeth are arc-shaped faces protruding outwards, the rubber pads are disposed in tooth grooves, so that abrasion is reduced, transmission efficiency is improved, and vibration of the gear teeth is reduced; airtightness is improved by the annular groove disposed on the inner wall of the stepped hole and a seal ring disposed in the annular groove; and stress generated in rotation of the gear teeth can be eliminated by notches disposed on the gear teeth.

Description

The secondary solar gear structure
Technical field
The utility model relates to field of gears, specifically a kind of secondary solar gear structure.
Background technique
Gear is the intermeshing mechanical parts that tooth is arranged of energy, is used for transferring power.In Planetary Gear Transmission, become sun gear with the external gear of the same axis of planet carrier, the sun gear outputting power, and transmit the planet wheel that is engaged on around it.
In long-term using process, in high-revolving situation, the surface abrasion of the gear teeth of secondary solar gear and vibration are larger, and the gear teeth of secondary solar gear can produce stress in rotation process, cause the gear teeth to produce distortion, thereby affected the working life of secondary solar gear.
The model utility content
The purpose of this utility model provides a kind of secondary solar gear structure, 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 reduce wearing and tearing, improves transmission efficiency, and is provided with rubber pad in the teeth groove, to reduce the vibration of the gear teeth; In addition, at the gear teeth breach is set, the stress that in rotation process, produces to eliminate the gear teeth.
The technical solution of the utility model is as follows:
A kind of secondary solar gear structure, include wheel disc, edge, surrounding around wheel disc has respectively a plurality of rectangle gear teeth, has teeth groove between adjacent two rectangle gear teeth, it is characterized in that: the middle part of described wheel disc is provided with step hole, the inwall of described step hole is provided with annular groove, the bi-side of described a plurality of rectangle gear teeth are outwards outstanding arc shaped surface, the crown of a plurality of rectangle gear teeth and bi-side have respectively wearing layer, the crown of a plurality of rectangle gear teeth is respectively equipped with breach, and the groove bottom in the described teeth groove is provided with rubber pad.
Described secondary solar gear structure is characterized in that: be provided with seal ring in the described annular groove.
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, have reduced wearing and tearing, have improved transmission efficiency, and have been provided with rubber pad in the teeth groove, have reduced the vibration of the gear teeth; The inwall of axis hole is provided with annular groove and seal ring is set, and has improved sealability; In addition, at the gear teeth breach is set, has eliminated the stress that the gear teeth produce in rotation process.
