Oldham coupling

Abstract

The invention discloses an Oldham coupling. A first half coupling, a second half coupling and a connecting plate form a main body structure of the Oldham coupling, a driving shaft and a driven shaft are connected through rotating shaft inserting grooves on the left side and the right side, a first inserting groove, a first threaded groove, an L-shaped screw rod, a second threaded groove and a screw are used for connecting and fixing the first half coupling, the second half coupling and the connecting plate, the L-shaped screw rod and the screw are in vertical relation so as to effectively prevent the L-shaped screw rod from being loosened, and a first connecting plate, a first mounting block, a first circular groove, a connecting groove and a triangular groove are used for forming a main body structure of the first connecting plate. According to the Oldham coupling, the L-shaped screw rod is perpendicular to the screw so as to effectively prevent the L-shaped screw rod from being loosened, motion and torque transmission between the first connecting plate and a second connecting plate are achieved, the acting force on a second mounting block can be reduced through a connecting blockand a triangular block, so that dispersion of the acting force is realized, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a slider shaft coupling. Background technique [0002] The slider coupling is also known as the metal cross slider coupling. Its slider is circular and made of steel or wear-resistant alloy. transmission. The slider coupling is composed of two bushings and a center slider. As a torque-transmitting element, the center slider is usually made of engineering plastics, and other materials, such as metal materials, can be selected in special cases. [0003] However, the half-couplings of the existing slider couplings and the connection discs are connected by simple bolts, which will easily cause the bolts to loosen after one end of use, which will affect the use effect. In addition, the transmission force of the existing connection discs is relatively concentrated. The use loss is large and the service life is reduced. For this reason, we propose a slider coupling.
