Abstract
The utility model discloses a secondary sun gear which comprises a gear disc. Multiple rectangular gear teeth are arranged at edges around the gear disc respectively, a gear groove is arranged between two adjacent rectangular wheel teeth, a step hole is arranged in the middle of the gear disc, multiple oiling holes leading to the gear grooves are arranged on the gear disc around the step hole, tooth tips of the multiple rectangular gear teeth and two side faces are provided with wear-resistant layers respectively, and the tooth tips of the multiple rectangular gear teeth are provided with notches. The secondary sun gear is compact in structure, and the wear-resistant layers are arranged on the surface of the gear teeth, so that wearing of the secondary sun gear is reduced; the multiple oiling holes leading to the gear grooves are arranged on the gear disc and used for injecting lubricating oil between two adjacent gear teeth, so that good lubricating effect is realized; and the gear teeth are provided with the notches to eliminate stress generated during rotation of the gear teeth, so that the service life of the secondary sun gear is prolonged.
Description
Technical field
The utility model relates to field of gears, specifically a kind of secondary solar 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 surface abrasion of the gear teeth of secondary solar gear is larger, and the gear teeth of secondary solar gear meeting generation stress in rotation process, causes the gear teeth to produce distortion, thereby has 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, and the surface of its gear teeth has wearing layer, and reducing wearing and tearing, and wheel disc is provided with a plurality of oil holes that lead to teeth groove, is used for injecting lubricant oil between adjacent two gear teeth, to play lubrication; 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, 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, be respectively equipped with a plurality of oil holes that lead to described teeth groove on step hole wheel disc on every side, the crown of described a plurality of rectangle gear teeth and bi-side have respectively wearing layer, and the crown of a plurality of rectangle gear teeth is respectively equipped with breach.
Described secondary solar gear is characterized in that: have output shaft pass described step hole and with the step 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 reduced the wearing and tearing of secondary solar gear; Wheel disc is provided with a plurality of oil holes that lead to teeth groove, is used for injecting lubricant oil between adjacent two gear teeth, has played good lubrication; Breach is set on the gear teeth, and the stress that produces in rotation process to eliminate the gear teeth has prolonged its working life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of secondary solar gear, include wheel disc 1, edge, surrounding around wheel disc 1 has respectively a plurality of rectangle gear teeth 2, have teeth groove between adjacent two rectangle gear teeth, the middle part of wheel disc 1 is provided with step hole 3, is respectively equipped with a plurality of oil holes 4 that lead to teeth groove on step hole 3 wheel disc 1 on every side, the crown of a plurality of rectangle gear teeth 2 and bi-side have respectively wearing layer 5, and the crown of a plurality of rectangle gear teeth 2 is respectively equipped with breach 6.
In the utility model, have output shaft pass step hole 3 and with step hole 3 interference fit.
