Description
Technical field
The present invention relates to electromagnetic clutch mounting and adjusting equipment and the method for large-scale heavy duty equipment, specifically relate to a kind of large-scale heavy duty installation electromagnetical clutch mounting and adjusting frock and method.
Background technology
The kind of clutch is a lot, but on large-scale heavy duty equipment, adopts electromagnetic clutch more.Electromagnetic clutch on large-scale heavy duty equipment, when the coil is energized, produce suction by lock ring adhesive, disc type spring deforms, lock ring is tightly adsorbed on wheel hub together with friction pad by suction, frictionally transmitting torque makes two halves clutch rotate simultaneously, reaches the object transmitting motion and power; When after coil blackout, suction disappears, and disc type spring band untie-sell ring and friction pad set back, and departs from wheel hub, makes left and right two halves clutch ensure reliable single action.If two halves clutch shaft line parallel but decentraction, then after clutch adhesive, its friction pad must come in contact slip a little with wheel fermented soya beans, salted or other wise, friction pad is inevitable not identical with the linear velocity of each contact point of wheel fermented soya beans, salted or other wise, but clutch system is in order to ensure synchronous axial system, only has and meets by distortion, otherwise the forced vibration of clutch can be caused, but when two halves clutch axis deviant exceedes certain value, vibration aggravation, thus system cannot ensure synchronously by distortion.If the concentric disalignment of two halves clutch, when axis inclination increases above the elastic range of disc spring, cause the significantly reduction of electromagnetic attraction, reduce from face stiction, the moment of torsion of clutch transmission also reduces, and makes it the function losing reliable interlock; If two halves clutch axis both decentraction, not parallel again, then the existing vibration of clutch, causes the significantly reduction of electromagnetic attraction again, then stiction reduces, and the moment of torsion that clutch transmits reduces, and the function of reliable interlock more easily lost by two halves clutch.Therefore, two halves clutch requires higher axiality and gap, if two halves clutch play is overproof, clutch the suction-combining force is inadequate, and frictional force does not reach design load, does not have enough transmitting torques, interlock just can occur and lost efficacy.As can be seen here, the mounting and adjusting of clutch, particularly require very high on large-scale heavy duty equipment, how effectively to ensure the installation accuracy of two halves clutch, ensure that the least possible loss ground of power of motor transmits, ensure that output shaft can not bear extra additional torque, thus ensure that clutch can run safely and reliably, this is also a difficult problem during large-scale heavy duty equipment is installed.

(2) direct adjustment act
With electromagnetic clutch, this adjusts decelerator base or bearing block as adjustment benchmark to the method, although simple and convenient, is subject to the impact of following factor:
A. by the impact of clutch configuration part distortion, end face run-out reaches 0.6mm ~ 0.8mm;
B. reductor high speed shaft bearing shaft is subject to the impact with radial clearance;
C. due to the deadweight of clutch, adjustment is measured in impact.
