Customized Aluminum Alloy Shaft Coupling Floating Coupling
Overview
Floating coupling is suitable for connecting two shafts without backlash slewing transmission. The coupling is composed of a half coupling with two grooves at two ends, an intermediate slider (two convex blocks arranged in a cross shape), a steel ball and two steel balls that are radially balanced by a spring. Paired devices are supported in the tangential holes of the coupling. When the active half coupling rotates, the torque is transmitted to the slider through the support and the steel ball, and then to the driven half coupling through the support. The gap between the steel ball on the slider and the support is determined by the spring. The support is heat-treated, so it will not be crushed by the steel ball. The support can be replaced when it is worn to increase the reliability of the coupling. The size of the torque transmitted by the coupling depends on the outer diameter of the half coupling, the material and the heat treatment process of the steel flow bearing.
