Problems solved by technology

[0002] The prior art is through forging (that is, blanking, heating, upsetting, forming, and punching in sequence), then heat treatment (that is, normalizing with a normalizing furnace), and then turning (that is, rough turning first). , finish car again), gear hobbing again (that is: the metal flow line is cut off by initial rolling, then fine rolling), and the finished product is obtained after shaving, heat treatment, and grinding. The planetary wheel provided by this prior art is not easy to assemble, structure It is complex and uses a lot of materials, and the planetary wheel obtained by the prior art processing technology uses a lot of materials, the processing is complicated, and the teeth are easy to break

Embodiment Construction

[0017] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] The embodiment of the present invention is a kind of planetary gear, such as figure 1 and figure 2 As shown, it includes: a metal ring 110, the outer wall of the metal ring 110 is provided with a plurality of gear teeth 111, and the inner wall of the metal ring 110 is provided with an annular groove along the direction of the ring 110 112. The plurality of gear teeth 111 are evenly distributed on the outer sidewall toward the outward direction of the outer sidewall.

[0019] Preferably, the metal ring 110 is integrally formed with the gear teeth 111 . It is also possible to directly weld the gear teeth 111 to the outer wall of the metal ring 110 .

[0020] The embodiment of the present invention also provides a processing technology for a planetary w...

Abstract

The embodiment of the invention provides a planet wheel and a processing technique thereof. The processing technique comprises the following steps of: (A) carrying out intermediate-frequency heating, 100T punch blanking and 400T press moulding extrusion on 20CrMnTi material in sequence to obtain a tooth-shaped product, then carrying out hyperthermia treatment after 80T punch side shearing, and then forging the tooth-shaped product; (B) hobbing the product obtained in the step (A) by using a hobbing machine; (C) shaving the product obtained in the step (B) by using a shaving machine; (D) carrying out heat treatment on the product obtained in the step (C) by using a continuous carburizing furnace; (E) grinding the product obtained in the step (D) by using an inner bore grinder and a plane grinder; and (F) cleaning the product obtained in the step (E) and coating antirust oil and packaging to obtain a finished-product planet wheel. The planet wheel obtained by the processing technique has the advantages of material saving, can be processed in a short time and has solid and durable teeth.
