A Forging Forming Process of Straight Oil Groove on Spherical Surface of Differential Planetary Gear

Abstract

The invention relates to the technical field of gear forging, in particular to a forging forming and machining technology for straight oil grooves in spherical surfaces of differential mechanism planet gears. The forging forming and machining technology comprises the steps of three-dimension modeling, machining and treating of dies, rough machining of forge pieces and finish machining of the forge pieces. The technological process steps are scientifically designed, and the problems that the production efficiency is low in the machining process of the oil grooves added in the spherical surfaces of the planet gears and the machining quality cannot meet the drawing requirements can be solved. According to the forging forming and machining technology, the overall forging accuracy of the differential mechanism planet gears is guaranteed, the energy consumption is lowered, the service life of the planet gears is prolonged, the finish machining time is shortened, the product production efficiency is improved, the production materials are saved, and the production cost input of enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of gear forging, in particular to a forging forming process of a straight oil groove on a spherical surface of a differential planetary gear. Background technique [0002] The differential planetary and half-shaft straight bevel gears are the key parts in the vehicle transmission system. Regardless of the vehicle's double-stage bridge or single-stage bridge, there are one or several sets of differential planetary, semi- Shaft straight bevel gears play a vital role in transmission systems. In order to ensure that the spur bevel gears of the differential are in good working condition during meshing rotation, the lubrication between the gear mounting surface and the differential housing is extremely important. Different axle manufacturers have adopted different methods, either It is to add an annular eccentric oil groove or three approximately equally divided radial oil grooves on the spherical surface of the ...
