DRIVE MECHANISM WITH SAFETY CASE

摘要

A drive mechanism with safety case is arranged as rubber protector inside which drive and driven shafts of machine are installed, and the ends of the safety case are at two sides rigidly fixed to those shafts with known methods. The rubber protector is arranged as sleeve with threaded surface. To the inner maximal diameter of the sleeve reinforced spring is installed, its diameter is equal to the inner maximal diameter of threaded grooves of the rubber sleeve. Shape of case in contour can be cylindrical, conical or profiled. The drive and driven shafts are connected to each other by spline joint with possibility of axial displacement.
