TESTING DEVICE FOR DYNAMIC CHARACTERISTIC OF BEARING

摘要

PURPOSE:To obtain respective dynamic characteristics, by making it possible to set an arbitrary miss alignment state to set various bearing states in a wide range by providing two load devices in parallel in the axial direction of the rotary shaft. CONSTITUTION:Two load devices 12 and 13 are fitted to the lower end of casing 9 of test bearing 4 through coupling seat 11 perpendicularly downward in parallel in the axial direction of rotary shaft 1. Two load devices 12 and 13 consists of load cells 14 and 15 which measure the static load fitted to coupling seat 11, bellows 16 and 17 which apply the load, and bellows fitting stands 18 and 19 which support bellows 16 and 17. The load is applied to test bearing 4 and the moment is given to it by pressure adjustment of the pressure oil input to two bellows 16 and 17, so that an arbitrary miss alignment state is set.
