hypoid gear
mechanical part
Also known as: offset spiral bevel gear
Quick Summary
A hypoid gear is a type of bevel gear used in automotive transmissions. Unlike traditional gears, the axis of a hypoid pinion does not intersect the axis of the gear. This design allows for a lower drive shaft position, which can improve vehicle styling and handling. The teeth on the pinion are spirally cut, and the gear teeth are cut nonradially. The term "hypoid" itself is an adjective derived from "hyperboloidal" and describes something that utilizes or relates to hypoid gears, such as a hypoid rear axle or hypoid grease.12
