Effects of Some Differences Of The Sizes of Ball Threads on The Operation Of The Thread
Dr. István Lakatos, Dr. Zoltán Varga
Little geometric deviation of the thread groove on the nut or pin could cause the deterioration of any ball thread's elements. Effects of alteration in connecting angle and action angle have been calculated and tested with measurement of well and not well machined ball threaded gears. A little bit bigger action angle than the nominal one causes ball blocking in the ball returning tubes and in case of outside values of other dimensions the ear of the returning tube can break mainly at extremely heavy load.
