Device for measuring revolution and revolving speed of rotary shafts

Abstract

The invention discloses a device for measuring revolution and revolving speed of rotary shafts. The device comprises a first semicircle ring, a second semicircle ring, multiple locking bolts, a magnetic tape ring, multiple magnetic tape ring screws, a magnetic sensor and multiple concentric adjusting screws, the first semicircle ring is fixedly connected with the second semicircle ring through the multiple locking bolts to form a circular ring, and the magnetic tape ring is fixedly bonded on the outer periphery of the circular ring through the multiple magnetic tape screws. A rotary shaft is sleeved in the first semicircle ring and the second semicircle ring in two different directions and fixedly locked through the locking bolts, the magnetic tape ring is fixed through the magnetic tape ring screws, signals are sensed and output through the magnetic sensor, and radial play eccentricity of the circular ring is adjusted by the concentric adjusting screws. The device for measuring the revolution and the revolving speed of the rotary shaft is suitable for non-detachable rotary shafts and effectively solves the problem that measuring devices cannot be sleeved or can be mounted only by demounting.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a measuring device for the rotation number and rotation speed of a rotating shaft. Background technique [0002] In research fields such as vehicles, manufacturing, and science, it is often necessary to measure various revolutions and rotational speeds in installed equipment to know the operating conditions of the rotating shaft. Especially in large-scale mechanical production equipment, due to the heavy workload and long working hours of each rotating shaft in the equipment, it is necessary to obtain the number of revolutions and speeds of each rotating shaft in the mechanical equipment in real time during operation, and based on these two parameters Monitor the safety performance of mechanical equipment in real time, prevent the failure of mechanical equipment without knowing it, and eliminate potential safety hazards during the operation of mechanical equipment.

AI Technical Summary

Problems solved by technology

[0003] Due to the rotation characteristics of the rotating shaft, it is impossible to measure the rotation speed and speed of the rotating shaft by means of conventional wire transmission signals. The existing method is to disassemble the mechanical equipment and put the measuring device into the rotating shaft to complete the measurement requirements.

This method wastes a lot of equipment dismantling, reinstallation and debugging time, and affects production. Once the measuring device is damaged, the process of equipment disassembly, reinstallation and debugging must be repeated, and this method is not suitable for the rotating shaft of non-detachable equipment.
