1results about How to "Improve dynamics" patented technology

The utility model relates to a kind of low additional bending moment welding film disc coupling structure, including axle, and axle both sides are connected by flexible film disc group installation disc;Flexible film disc group includes flexible film disc and adapter disc, adapter disc is connected with axle by transmission bolt and self-locking nut, and adapter disc is connected with installation disc by flexible film disc;Flexible film disc is connected installation disc and adapter disc by vacuum electron beam welding process, and flexible film disc inner circumferential end portion is equipped with flexible inner welding surface.The utility model is connected by welding instead of bolt, effectively reduce the weight of coupling;While by flexible film disc close to installation disc, so that gravity position is close to installation disc end face, additional bending moment to shaft head can be effectively reduced, improve dynamic characteristics, adapt to high speed application.
