Description
Technical field
The electromagnetic clutch that the present invention relates to large-scale heavy duty equipment is installed adjustment equipment and method, specifically relates to a kind of large-scale heavy duty installation electromagnetical clutch frock and the method adjusted is installed.
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, in the time of coil electricity, produce suction by lock ring adhesive, disc type spring deforms, suction is tightly adsorbed in lock ring on wheel hub together with friction pad, frictionally transmitting torque rotates two halves clutch simultaneously, reaches the object of 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 can ensure reliable single action.If two halves clutch shaft line parallel but decentraction, 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 rotation, only has by distortion and meets, otherwise can cause the forced vibration of clutch, but in the time that 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, in the time that axis gradient increases to the elastic range that exceedes disc spring, causes the significantly reduction of electromagnetic attraction, reduce from face stiction, the moment of torsion of clutch transmission also reduces, and makes it to lose the function of reliable interlock; If both decentraction of two halves clutch axis are not parallel again, the existing vibration of clutch, causes the significantly reduction of electromagnetic attraction again, and stiction reduces, and the moment of torsion that clutch transmits reduces, and two halves clutch is more easily lost the function of reliable interlock.Therefore, two halves clutch requires have 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, there is no enough transmitting torques, loses efficacy just can there is interlock.As can be seen here, the installation adjustment of clutch, particularly on large-scale heavy duty equipment, require very high, how effectively to ensure the installation accuracy of two halves clutch, ensure that the least possible loss of power of motor ground transmits, ensure that output shaft can not bear extra additional torque, thereby ensure that clutch can move safely and reliably, this is also a difficult problem during large-scale heavy duty equipment is installed.
The installation adjustment of existing large-scale heavy duty equipment clutch, the general following two kinds of methods that adopt more:
(1) draw steel wire method
The method is drawn steel wire taking high speed shaft bearing as benchmark, makes the center of four bearing saddle bores.The advantage of this method is that required survey tool is very simple, easily preparation, and practical application is visual in image.Shortcoming is: certainty of measurement is subject to steel wire amount of deflection (when horizontal level is measured), the material of steel wire swing and steel wire, and the impact of diameter and measuring appliance requires survey crew to have more skilled manual skill simultaneously.
(2) direct adjustment act
With electromagnetic clutch, this adjusts decelerator base or bearing block as adjusting benchmark to the method, although simple and convenient, be subject to the impact of following factor:
A. be subject to the impact of clutch configuration part distortion, end face run-out reaches 0.6mm～0.8mm;
B. be subject to reductor high speed shaft bearing shaft to the impact of radial clearance;
C. due to the deadweight of clutch, impact is measured and is adjusted.

(2) rotor axis of electric and reductor power shaft are hung out, pack frock into, wherein, driving shaft is contained on the bearing block of motor shaft two sliding bearings, and driven shaft is contained in reductor power shaft diaxon bearing, and bearing block upper cover closes.
(3) bearing block of adjustment motor shaft two sliding bearings, levelling capturing driving shaft, tightens foundation bolt.
(4) adjust benchmark taking the driving shaft axis after levelling capturing as installing, unclamp the foundation bolt of reductor, adjust the position of reductor, the axiality of measurement frock driving shaft, driven shaft and in opposite directions end face axial fit clearance size, adjustment limit, limit is measured and is calculated, so repeatedly, until the axiality of frock driving shaft, driven shaft and the designing requirement of end face axial fit clearance size conforms;
(5) foundation bolt of fastening reductor, fixing reductor position, remains unchanged the relative position of itself and motor output shaft end bearing block;
(6) after fastening, check is confirmed one time again;
(7) pull down frock;
(8) two halves of electromagnetic clutch are contained in respectively on motor output shaft and reductor power shaft;
(9) rotor is hung on to bearing block, bearing block upper cover closes; The gear driving pair of reductor is hung in to box body of speed reducer, and case lid closes.
