Description
Technical field
The utility model relates to field of measuring technique, particularly relates to the shaft coupling centering measurer in the centering field.
Background technology
Shaft coupling is main drive shaft and the driven shaft that is used for connecting in the different institutions, make it common rotation to transmit the mechanical component of moment of torsion, shaft coupling is centering accurately when mounted, centering, so that the rotation center strictness of two axles that connected is concentric, otherwise the vibration values that can cause rotating machinery exceeds standard, will on shaft coupling, cause very big stress, and will seriously influence axle, bearing and axle are gone up the operate as normal of other parts, even cause the vibration or the damage etc. on entire machine and basis, the normal operation of rotating machinery in serious threat, especially high rotating speed equipment, very strict to the data demand of shaft coupling centering.
But, the diaxon that shaft coupling connected, can not be accurately absolute owing to make and install, and the elastic deformation and the temperature deformation of work basis, frame and other parts during stand under load, the two axial lines that shaft coupling connected will produce relativity shift inevitably, the relativity shift that may be occurred by the connection diaxon has: axial dipole field figure, radial deflection figure and angle deflection graph, and three kinds of combination skews that skew occurs simultaneously.
Therefore, the centering of shaft coupling is one of working link very important in rotating machinery installation and the maintenance process.
The purpose of centering is to make the continuity curve of the center line of an armature spindle for the center line of another armature spindle.Because the axle of two rotors is to connect with shaft coupling, so as long as two couple of shaft coupling wheel center line continues, two centre of rotor lines must be the curves of a continuity just also so.Two pairs of wheel centers of shaft coupling are continued, then must satisfy following two conditions:
1. make two to the coincidence of wheel center, the cylindrical of two pairs of wheels is overlapped;
2. make the faying face (end face) parallel (two center lines are parallel) of two pairs of wheels.
General shaft coupling centering measurer is a dial gauge now, utilize simultaneously two dial gauges to wheel shaft to radially carry out the jiggering centering, but when main equipment is carried out jiggering, because rotor is very heavy, must many people carry out jiggering to rotor, causes the amount of labour used big, labor strength is big, and efficient is very low, influences power plant's progress of repairing time, and risk is than higher simultaneously.If adopt crane, lead chain and cooperate, utilize suspention to be wrapped in wire rope on the rotor and form rotation and carry out jiggering and measure owing to hang the force unbalance of winding, axle and watt between side clearance will cause axle and watt malalignment, measure inaccurate.Not only waste time and energy, and extremely inconvenient.Moreover because shaft coupling is bigger to wheel thickness, it is longer to cause dial gauge table bar to lean out, and measurement data is also very unstable.
Therefore be necessary to design a kind of shaft coupling centering measurer, to address the above problem.
