Service HotlineTherefore, there is a need to design a bearing retaining ring disassembly and installation device that facilitates the installation and disassembly of the bearing retaining ring, and is safe and reliable.
The spring washer is designed for screw backstop, usually a single-turn cylindrical coil spring. In order to improve its backstop function, there is also an integrated spring washer. Its structure is that the inner ring of the flat washer has multiple wings. Fold into spring tabs. Another type of washer used for backstop similar to spring washers is a serrated lock washer. However, this kind of lock washer usually has a small thickness, which is formed by folding the inner ring or the outer ring of the washer on the plane. When tightening, the elastic force is small, and the second is easy to be flattened, so that the stop The retreat function is still not strong enough.
screw generally includes a screw head, a screw part and a screw tail. In the traditional screw processing, the screw head and the screw part are punched out first, and then the threaded part is processed on the screw shank through the turning process. When the screw head is traditionally punched, the screw head is easily damaged due to the large punching force.
At present, the washing machines used in the domestic market, especially the large-capacity washing machines, have high rotational inertia due to their large washing capacity. The wear between the input shaft and the clutch sleeve will cause the increase of the axial clearance. There will be strong shaking and loud noise, which will increase the wear and tear and affect the service life. In the prior art, the wave washer is used to prevent loosening and buffer shock, so that the gap between the input shaft and the clutch sleeve will not increase due to the wear of the two, which plays the role of automatic gap compensation, so as to ensure the clutch Smooth rotation, low noise and light wear ensure the reliable service life of the clutch.
hand screw is a screw with a plastic head, and the user fixes the hand screw by turning the plastic head by hand. At present, a hand-tight screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of ordinary screws, and the height is 11 cm. The screw of the hand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the hand screw.
