Threaded washer and installation method thereof

Abstract

The invention discloses a threaded washer and an installation method thereof. The threaded washer comprises a threaded washer body, a connected part and a bolt, and one end of the bolt is in threadedconnection with the threaded washer body; the other end of the bolt is in threaded connection with the connected part, and the threaded washer is composed of a spiral body with metal plate threads, asupport body with metal plate threads, an arc-shaped body, a threaded process gap and a disc flange; one side of the spiral body with the metal plate threads is provided with the support body with themetal plate threads, and one side of the support body with the metal plate threads provided with the arc-shaped body; and the outer side of the arc-shaped body is connected with the disc flange, andthe middle diagonal of the threaded washer body is provided with the threaded process gap. The pre-tightening force is small, and the elastic range is wide; a part of dynamic load of fasteners can beabsorbed while the purposes of effective fastening and anti-looseness are achieved, so that the fasteners including the bolt are protected from being damaged; and the weight is light.

Description

technical field [0001] The invention relates to the technical field of thread transmission and fasteners in mechanical engineering, in particular to a threaded washer and an installation method thereof. Background technique [0002] At present, whether it is a standard spring washer, a wave spring washer, or a disc spring washer, although the friction of the fastener can be increased by the elastic force to achieve anti-loosening, and the cost is low and the installation is convenient; however, because of its small elastic range, the friction Insufficient force, the anti-loosening ability and reliability are very low; at the same time, the elastic force increases, the prestress of the fastener also increases, and the fastener is easy to break, resulting in potential safety hazards; therefore, in important load-bearing structure connection parts Not adopted. [0003] Therefore, it is necessary to invent a threaded washer and an installation method thereof to solve the above ...
