A mechanical speed detection and tracking adjustment device

Abstract

The invention discloses a mechanical rotating speed detecting and tracking adjusting device. The mechanical rotating speed detecting and tracking adjusting device mainly comprises a base, an upper cover, a cross shaft, a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, a cylinder gear and an input shaft. The first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear are arranged in the four directions of the cross shaft, and the adjacent bevel gears are engaged with each other. The input shaft is connected with the first bevel gear through a connecting key. The cylinder gear is fixed to the side end face of the third bevel gear through a screw. A transverse shaft is arranged on the base, and the right end of the transverse shaft stretches out to be connected with a rotating speed adjusting device of an outer tested rotating piece. After the cylinder gear detects the rotating speed of the outer tested rotating piece, the rotating speed is transmitted to the third bevel gear and compared with the target rotating speed of the first bevel gear, and the rotating speed difference exists, the cross shaft and components on the shaft integrally rotate around the transverse shaft of the cross shaft, the rotating transverse shaft drives the rotating speed adjusting device of the tested rotating piece, and the rotating speed of the tested rotating piece is made to automatically track the target rotating speed.

Description

technical field [0001] The invention relates to a speed detection device, in particular to a device for detecting the rotation speed of a rotating machine and performing feedback and tracking adjustment, in particular to a mechanical rotation speed detection and tracking adjustment device. Background technique [0002] In engineering practice, various occasions that need to measure the speed are often encountered. For example, in the test operation and control of rotating equipment such as engines, motors, machine tool spindles, and wheels, it is usually necessary to measure and adjust the speed and direction of time-sharing or continuous. At present, there are mainly three types of speed sensors that are most used in the market: photoelectric, Hall and magnetoelectric gear speed sensors. The photoelectric type needs to paste an identifiable cursor on the measured object; the Hall type has poor interchangeability, the signal changes with temperature, and the nonlinear output...
