Problems solved by technology

[0003] When calibrating the coaxiality between the transmission shaft of the driving equipment and the transmission shaft of the driven equipment, first remove the coupling, and then use a special tool to calibrate. Now the more common calibration tool is a laser calibrator, laser calibration The instrument has the characteristics of high precision and simple operation, but the price is relatively high

Embodiment Construction

[0047] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] First of all, it needs to be explained that the present invention aims to provide a centering device, by setting the first adjusting tool 1 and the second adjusting tool 2 having an annular part coaxial with the first transmission shaft 3, and performing centering During operation, measure the annular part of the first adjusting tool 1 through the dial indicator 24 or the dial gauge of the second adjusting tool 2 rotating around the axis of the second transmission shaft 4, thereby judging and calibrating the first transmission shaft 3 and the second transmission shaft 3. Concentricity between axes 4. Within the scope of this technical idea, the protectio...

Abstract

The invention discloses a centering apparatus and a centering method. The centering apparatus comprises a first adjusting fixture (1) and a second adjusting fixture (2), wherein the first adjusting fixture (1) is provided with an annular portion, when the first adjusting fixture (1) is connected with a first transmission shaft (3), the axis of the annular portion is superposed with the axis of the first transmission shaft (3), the second adjusting fixture (2) comprises a measuring member connected with a second transmission shaft (4) and a micrometer (24) or a dial gauge installed on the measuring member, and when the measuring member rotates around the axis of the second transmission shaft (4), the contact of the micrometer (24) or the dial gauge is in sliding contact with the annular surface of the annular portion. According to the invention, the centering apparatus can rapidly finish coaxiality check between the transmission shaft of a driving device and the transmission shaft of a driven device and is low in manufacturing cost and small in errors.

Description

technical field [0001] The invention relates to the field of mechanical devices, in particular to a centering device and a centering method for calibrating the coaxiality of two shafts. Background technique [0002] In industrial production, the driving equipment is often used to drive the driven equipment to run, and the transmission shaft of the driving equipment is generally connected to the transmission shaft of the driven equipment through couplings and other devices to output power. In order to reduce the noise and power loss during the transmission process and ensure the safe operation of the equipment, it is necessary to ensure the coaxiality between the transmission shaft of the driving equipment and the transmission shaft of the driven equipment. For example, in order to ensure the safe operation of the wind turbine generator, the coaxiality between the generator and the transmission shaft of the gearbox must be regularly checked to make it run within the allowable...
