Title Planetary differential bench design
Abstract
Planetary differential is widely used in various types of military and civilian sector, Carrying capacity, maximum speed and efficiency is a measure of an important indicator of good or bad performance differentials.
Planetary differential bench instruments to measure these indicators.
One type of planetary differential bench generally correspond to one or several planets differential. The design to be measured are two planetary differential input, single output. It has small size, high speed input shaft spacing smaller features. This design features a planetary differential bench to be measured according to the planetary differential
Design. Test station planetary differential power is transmitted through the belt to the input shaft to the input shaft to solve two problems of smaller pitch. Planetary differential clamp load brake clamp load bearing and radial offset are adjustable, the coupling method using the link connection cord wound. This error can be reduced as much as possible to bring the installation, so that the performance of the measurement is more accurate.
