The hypoid pinion gear is bigger than the spiral bevel one for the same crown gear size and so more durable; on the other hand there is more sliding at the hypoid gear
mesh due to the pinion offset.
Army and Southwest Research Institute (SwRI), investigation into HMMWV differential efficiency testing was conducted for super-finished hypoid gear
sets over a Peacetime - Operational Mode Summary/Mssion Profile (OMS/MP)  developed for the HMMWV.
Dynamics of a hypoid gear
pair considering the effects of time-varying mesh parameters and backlash nonlinearity, Journal of Sound and Vibration 308(1-2): 302-329.
 construct the digital real model of hypoid gear
aiming at the wear of tooth surfaces by using non-feature block interpolation technique.
 established a single degree-of-freedom hypoid gear
pair dynamic equation, which included the time-varying stiffness, transmission error, and backlash, and obtained the FFT responses.
For instance, if you spill differential oil (aka hypoid gear
oil) on your clothes, you can wash it 100 times, but you'll never get the horrible stink out of it.
Both feature an upgraded drive unit, a stationary-mounted drive motor to eliminate power cable flexing during steering, and a hypoid gear
set for quieter motor operation.
In February, Spicer India, Ltd., a Dana majority-owned venture with Anand Automotive Systems, broke ground for a 50,000-square-foot (4,645-square-meter) hypoid gear
manufacturing facility in Chakan, India.
This effort, initiated in 1952 and completed in 1960, involved a multiphase project to develop test procedures for the evaluation of hypoid gear
lubricants and to study the loading, temperature, and sliding velocity conditions of automotive hypoid gears
In response to customer requests, the quill offers the same product features such as patented hypoid gear
technology, maintenance-free grease lubrication, compact modular housing combined with a new, improved c-face quill input, and antimicrobial Alesta AM powder coat finish.
-- Check the levels and quality of the engine oil, hypoid gear
oil, shaft drive, hydraulic fluid, coolant, and fuel.
Components will mainly be sourced in China except for the hypoid gear
set, which will be produced in the company's Nagoya facility in Japan.
