A two-redundant linear displacement sensor mechanical anti-twist device

Abstract

The invention belongs to the field of sensors, and relates to a mechanical anti-twist device for a two-degree linear displacement sensor, comprising a connecting head (1), a bearing retaining ring (2), a bearing (3), a bearing jacket (4), a bushing (5) ), connecting rod mounting bracket (8), iron core (9); among them, the right bearing (3) is installed on the connector (1), the bearing shell (4) is installed, and then the left bearing (3) is installed , through the bearing retaining ring (2) to limit the position, insert the iron core (9) into the light hole of the connecting rod mounting frame (8), and fix it with laser welding, and connect the connecting rod mounting frame (8) and the bearing shell (4) Connect, insert the bushing (5) from one side, and wrap the edge of the bearing shell (4) and the connecting rod mounting bracket (8) with the pressing edges of the bushing (5) on both sides. After a fault occurs in the connecting structure, the device can still have the anti-twist function to ensure the normal operation of the linear displacement sensor.

Description

technical field [0001] The invention belongs to the field of sensors, and is a mechanical anti-twist device of a two-degree linear displacement sensor. Background technique [0002] The single redundancy sensor does not need to consider the anti-twist problem of the iron core during use. Since the sensor is an important feedback element, more and more redundancy sensors are used in current engineering applications to ensure the reliability of the data. The sensor is often connected to the rotating structure during installation, which is easily affected by torque, and its movement frequency is high. When the allowance increases, the anti-twist problem of the iron core must be considered. [0003] At present, the commonly used anti-twist measures for the iron core of the dual redundant sensor are to connect the bearing to prevent the connection head from rotating under the action of external force to drive the iron core to rotate. The connection between the mounting bracket t...
