Abstract

The invention discloses a coupling with an elastic spider. The coupling mainly comprises a left half coupling, a right half coupling and the elastic spider, wherein both the left half coupling and the right half coupling are provided with center holes, quincuncial double wedges are arranged on the end face of the left half coupling and the right half coupling respectively, a cylindrical hole is formed in the center of the elastic spider, bosses are arranged on the left half coupling and the right half coupling respectively and are located on the inner sides of the double wedges, the two side faces of each double wedge are shaped like concave arcs, the elastic spider is installed between the left half coupling and the right half coupling, and a cylindrical boss of the elastic spider is installed in a gap between the double wedges of the left half coupling and the right half coupling.

Description

technical field [0001] The invention relates to the technical field of shaft couplings, in particular to a quincunx elastic shaft coupling. Background technique [0002] Due to various reasons, the center of mass or the main axis of inertia of the coupling does not coincide with the axis of rotation, and the phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (mode shape) will occur during operation. This unbalanced phenomenon is inevitable. Vibration of the shaft system is caused, which affects the error, the deformation of the shaft under load, the deformation of the base, the wear of the bearing, and the temperature change (thermal expansion and contraction) affect the normal operation and service life of the machine. The two shafts connected by the coupling are due to Relative displacement is caused by various factors such as manufacturing errors, installation, and relative movement between components. In general...
