AN IMPROVED MOULDED TYPE GUIDE PAD STOP FOR GUIDE BEARING OF HYDRO GENERATORS

摘要

In the new design of guide stop (Ref Fig. No.02), main consideration were to increase circulation of oil, proper bonding of insulation material and to eliminate complicated machining. In the new design instead of machining from a heavy block of steel it is made from six thick steel plate, which is trimmed and bent at both the ends to get the required size and shape of pad stop, without any machining. The pad stop made by bending the steel plate is moulded with epoxy fiber glass insulation to make it a monolithic mass. There is no danger of knocking down of the insulating from pad stop during working condition.
