Method for detecting contact pressure between conductive slip ring and conductive brush wire

Abstract

The invention provides a method for accurately detecting the contact pressure between a conductive slip ring and a conductive brush wire. The method comprises the following steps: a cross-shaped sliding table is adjusted; a brush wire component to be detected is mounted on a measuring device, and the cross-shaped sliding table is adjusted in the Y direction to enable the brush wire to be detected to be in correct contact with a circular arc of a measuring head according to the working conditions of a product; a connecting rod of the measuring device is slowly swung to enable the brush wire to be in sliding contact with the circular arc of the measuring head, a measuring head system measures and displays the component force, in the force-measuring direction of a sensor, of the contact pressure between the brush wire and the measuring head in real time, the normal direction of a common tangent at the contact point of the brush wire and the circular arc of the measuring head is consistent with the force-measuring direction of the sensor in the swinging measurement process, and the displayed pressure is the contact pressure between the brush wire and the slip ring. The method can accurately detect the practical contact pressure comprehensively formed by factors including the shape error and mounting position error of the brush wire, the elastic coefficient of a brush wire-slip ring contact pair and the like, so that a scientific method is provided for control and adjustment of the contact pressure between the brush wire and the slip ring, the design requirement for reliability of the contact pressure between the slip ring and the brush wire is effectively guranteed.

Description

technical field [0001] The invention relates to a method for detecting the contact pressure of the brush wire of a conductive slip ring, which can accurately simulate the real working state of the brush wire and the slip ring, reproduce the deformation of the brush wire under actual working conditions, and measure the pressure of the brush wire during operation through a measuring device. It provides an effective guarantee for improving the reliability of slip ring brush wire contact compatibility and prolonging the service life of the slip ring brush wire contact compatibility system. It is especially suitable for the control of slip ring-brush wire contact pressure. Where required. Background technique [0002] In some cases where current transmission from fixed equipment to rotating equipment is required, a slip ring assembly is often used to perform electrical transmission in the form of sliding contact between fixed brush wires and rotating slip rings. In order to ensu...
