Adjusting ring device for measuring revolution and speed of rotary shaft

Abstract

The invention discloses an adjusting ring device for measuring revolution and speed of a rotary shaft. The adjusting ring device comprises a first positioning half ring, a second positioning half ring, a first middle half ring, a second middle half ring, a magnetic tape ring, a compressing end plate, an adjusting ring capable of rotating with the rotary shaft, and a magnetic sensor for sensing magnetic signals on the magnetic tape ring. The first positioning half ring and the second positioning half ring are connected to form a positioning ring. The first middle half ring and the second middle half ring are connected to form a middle ring. The outer wall of the adjusting ring is attached to the inner wall of the middle ring. The magnetic tape ring is adhered to the outer periphery of the middle ring. The positioning ring and the compressing end plate are respectively fixedly connected to the middle ring. The adjusting ring device is applicable to rotary shafts not removable. The problem that the measuring device cannot be nested in or can only be mounted by demounting is solved. The adjusting ring device has the advantages of simplicity in operation, convenience in demounting and mounting, stability in operation, high measuring precision and the like.

Description

[0001] technical field [0002] The invention relates to the field of measurement technology, in particular to a device with an adjustment ring for measuring the rotation number and rotation speed of a rotating shaft. [0003] Background technique [0004] 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 o...

Problems solved by technology

[0005] 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.
