Abstract
The utility model discloses a primary sun gear which comprises a gear disc. A plurality of rectangular gear teeth are respectively 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 corrosion-resistant layer is arranged on the surface of the gear disc, a shaft hole is arranged in the middle of the gear disc, a plurality of radial grooves are arranged on the gear disc surrounding the periphery of the shaft hole, and a bushing is nested on the inner wall of the shaft hole. The primary sun gear has the advantages that the primary sun 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 sun gear is improved; the corrosion-resistant layer is arranged on the surface of the gear disc, and accordingly the service life of the sun gear is prolonged; and the multiple radial grooves are arranged on the gear disc surrounding the periphery of the shaft hole to bring convenience for assembling the sun gear and an output shaft.
Description
Technical field
The utility model relates to field of gears, specifically a kind of one-level sun gear.
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 axial float of sun gear is larger, produces easily vibration noise, and wearing and tearing are larger, affects the working life of sun gear.
The model utility content
The purpose of this utility model provides a kind of one-level sun gear, 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 sun gear; The surface of wheel disc has corrosion-resistant coating, to prolong the working life of sun gear; Wheel disc around axis hole is provided with a plurality of radially flutings, to make things convenient for the assembling of sun gear and output shaft.
The technical solution of the utility model is as follows:
A kind of one-level sun gear, include wheel disc, edge, surrounding around wheel disc has a plurality of rectangle gear teeth respectively, 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 surface of described wheel disc has corrosion-resistant coating, and the middle part of wheel disc is provided with axis hole, and the wheel disc around axis hole is provided with a plurality of radially flutings, is set with lining on the described shaft hole inner wall.
Described one-level sun gear is characterized in that: have output shaft to pass described axis hole, a side of axis hole is provided with keyway, and the outer wall of output shaft is provided with the key post and is stuck in the keyway, and wheel disc and output shaft are combined.
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 sun gear; The surface of wheel disc has corrosion-resistant coating, has prolonged the working life of sun gear; Wheel disc around axis hole is provided with a plurality of radially flutings, has made things convenient for the assembling of sun gear and output shaft.
