AI Technical Summary

Technical Problem

In the existing technology, the counterweight component of the hollow reactor winding shaft is fixed by a nut, which is difficult to maintain stability under dynamic working conditions, resulting in the nut loosening and falling off, affecting the continuity of the winding process and the consistency of product quality.

Method used

The connection method using a hole and spring pin clamp replaces the nut fixation. The axial position of the counterweight is automatically adjusted according to the speed and load changes. The rigid-flexible design of the spring pin resists dynamic impact and vibration. A pressure sensor is embedded on the surface of the counterweight sleeve to monitor and adjust the speed in real time.

Benefits of technology

It improves the reliability and stability of the connection, reduces process interruptions, extends the connection life between the counterweight and the pay-off shaft, reduces maintenance frequency, and improves production efficiency and product quality consistency.

Abstract

The application provides a hollow reactor winding shaft locking device and relates to the field of reactors. The hollow reactor winding shaft locking device comprises a winding shaft, a counterweight member and a spring pin. The winding shaft is provided with a plurality of first matching holes along the axial direction of the winding shaft. The counterweight member is connected with the winding shaft. The counterweight member is provided with a plurality of second matching holes. The plurality of first matching holes and the plurality of second matching holes are in one-to-one correspondence. The spring pin is connected with a clamp. The clamp is used for clamping into the corresponding first matching hole and second matching hole. The counterweight member is a counterweight sleeve which is sleeved on the winding shaft. The spring pin comprises a cylindrical pin and a ring spring. The cylindrical pin is used for inserting into the corresponding first matching hole and second matching hole. The ring spring is fixedly connected with the cylindrical pin. The clamp is a clamping block. The counterweight member is connected in the mode of "one-to-one correspondence of the first matching hole and the second matching hole + spring pin clamp locking", and replaces the traditional nut fixing. The one-to-one correspondence of the first matching hole realizes the accurate matching of the axial position. The clamp of the spring pin is clamped into the matching hole, and mechanical hard constraints are formed, which can resist periodic impact and vibration under dynamic working conditions.
