Description
Technical field
The present invention relates to long shaft coupler technical field more particularly to a kind of long shaft coupler concentricity adjusting process.
Background technique
In metallurgical machinery equipment installing engineering, more particularly, to the installation of large-scale rotation mechanical equipment, to motor and subtract
The concentricity of fast machine transmission shaft requires very strict.According to gb specification《GB50231-2009》General requirement, two axle center diameters
It must be controlled within 0.05mm to displacement installation accuracy, two axial lines inclination control is within 0.05/1000.And theoretically
It says, the concentricity Adjustment precision of shaft coupling is higher, and the vibration and noise that equipment generates when rotating is lower, and then can effective extending shaft
It holds, the service life of bearing shell, improves safety when equipment operation.
In general, usually because speed reducer volume is big, weight weight, Normal practice when shaft coupling mounting and adjusting is with speed reducer
On the basis of input shaft, dial gauge (precision 0.01mm) is set up in motor side, adjustment direction is determined by the reading of dial gauge, from
And motor position is adjusted, it is finally reached the purpose of adjustment shaft coupling concentricity.But the above method of adjustment is only applicable to two sides
The case where half a coupler is connected directly has two sides half a coupler and non-straight when metallurgical system rotates mechanical equipment installation sometimes
Connect connected, usually have one section of connecting shaft in-between, the usual mating connecting shaft uses universal shaft, but Hooks coupling universal coupling because
Itself defect is not suitable for the high revolution of transmitting, high torque (HT), and the torque transmitted can greatly reduce, so real by production
Jian Houyou part producing enterprise has selected universal shaft being changed to rigidity straight axis.The selection of rigidity straight axis greatly improves shaft coupling
Two half a couplers are first inputted axis connection with motor output shaft and speed reducer respectively using preceding, then corrected by the requirement of concentricity
Concentricity between the half a coupler of two sides, but can not be direct first because two sides half a coupler spacing is larger using conventional method
It is measured and is adjusted using dial gauge, if secondly intermediate connecting shaft is pre-installed on motor output shaft half a coupler, then set up
Dial gauge measurement adjustment can be self-possessed larger because of intermediate connecting shaft, and motor side jiggering is difficult, be not easy to adjustment motor position, and because
Its sagging reason of being self-possessed, it is difficult to set up dial gauge, eventually lead to adjustment effect and have a greatly reduced quality.In this case, it usually answers
Shaft coupling concentricity is adjusted using laser alignment instrument, laser alignment instrument is vast because its Adjustment precision height, applied widely
Engineers and technicians are favored, but because it is expensive, and operating process is complicated, cumbersome without being widely used.
In view of this, how a kind of long shaft coupler concentricity adjusting process is provided, and it is simply, convenient, efficiently adjust length
The concentricity of axis shaft coupling, just at those skilled in the art's urgent need to resolve the technical issues of.
Summary of the invention
The technical problem to be solved in the present invention is that：How a kind of long shaft coupler concentricity adjusting process is obtained, it can letter
