Description
Technical field
The present invention relates to a kind of motor test spacer type coupling and assembly and disassembly methods thereof.
Background technique
" shaft coupling " testing apparatus designs according to wind-driven generator shaft extension structure; But the wind-driven generator shaft extension is different from other products; For example: steam turbine generator dynamic balance running device is a pattern of confirming coupling according to vapour generating shaft extension structure, can directly utilize tapering or keyway on the generator shaft extension, makes test send out arbor with coupling and vapour and puts in capable secure attachment; Promptly come transmitting torque with keyway; Thereby reach the purpose of " shaft coupling " test, and a zero draft, two no keyways on the shaft extension of wind-driven generator, if coupling is used in the usefulness test of type in the past; Then can't guarantee itself and the connecting of wind-driven generator shaft extension, let alone transmitting torque is realized the purpose of " shaft coupling " test.Conventional design proposal, test are with the mode of coupling employing hot jacket, and test is adopted the interference fit transmitting torque with the internal diameter of coupling and the shaft extension of wind-driven generator; Calculate a rational magnitude of interference, after test is heated to uniform temperature with coupling before, be placed on the wind-driven generator shaft extension; Again the coupling heating is taken out after test is accomplished, but because wind-driven generator is a product that demand is bigger, the efficient of doing experiment like this is too low; Can't satisfy the production needs, and because the wind-driven generator shaft extension is longer, heating and cooling repeatedly; Can influence the mechanical property of shaft extension part, product is produced harmful effect.Traditional coupling assembly and disassembly methods, it is low to have safety coefficient during dismounting, dismounting is time-consuming, effort, the dismounting back is bigger to the damage of motor shaft extension, the dismounting back is most of fastening bigger with part injury, can not the secondary use etc. shortcoming.
Summary of the invention
The object of the invention promptly is to overcome the deficiency of existing technology, and a kind of easy accessibility, long service life, motor test spacer type coupling safe in utilization, reused and assembly and disassembly methods thereof are provided.
The objective of the invention is to realize: motor test spacer type coupling through following technological scheme; It comprises inner spacing collar and the trim ring that is placed in outside the alternator shaft; The external axle sleeve of encapsulation outside inner spacing collar; And at least six M20 bolts, the major part cylindrical of described inner spacing collar links to each other with the inner stopper of trim ring, and described bolt links to each other with external axle sleeve, alternator shaft with bolt hole on the trim ring through bullet pad, plain cushion; Having the narrow groove of five equilibrium on the described inner spacing collar, is the elasticity steel bushing that a kind of wall approached and had male cone (strobilus masculinus); Described external axle sleeve has inner conical surface.
Motor test spacer type coupling assembly and disassembly methods; It comprises that motor test spacer type coupling is packed into and motor test spacer type coupling is dismantled; Wherein, motor test spacer type coupling is packed into: with pack into the shaft extension of motor of spacer type coupling, with common wrench earlier with 1/3rd places of place, diagonal angle bolton to bolt; Successively with 6 bolton; Again the diagonal angle bolton is arrived 2/3rds of bolt, successively with 6 bolton, final force square wrench is adjusted to the design moment requirement with all bolton;
The dismounting of motor test spacer type coupling: pine removes the clamping bolt of trim ring and external axle sleeve, keeps two bolts of symmetry, and makes itself and outer shaft be with the distance about 3 button silks; Inner spacing collar is withstood through cushion block in top with jack, and external axle sleeve is withstood through U-iron, screw rod in the bottom of jack, rotates jack work; Separate until inner spacing collar, external axle sleeve; Simultaneously, the effect of jack stay hook prevents to tear open that jack drops in the coupling process.
Described common plate hand comprises special-purpose double off-set spanners; It is 350～410Nm that described design moment requires.
The invention has the beneficial effects as follows: the present invention provides the motor test spacer type coupling and the assembly and disassembly methods thereof of a kind of easy accessibility, long service life, safe in utilization, shaft coupling, has the following advantages:
(1) product structure is simple, has reduced cost of production;
(2) adorn, tear open conveniently, and the time spent is short, has improved manufacturing efficiency;
Safe and reliable when (3) using; After the use, the motor shaft extension can not produce problems such as size distortion and surface failure, and the inner spacing collar of coupling automatically restores to original shape; Can not produce problems such as size distortion and inside and outside surface failure; Have and do not damage the motor shaft extension, prolong the working life of inner spacing collar, do not influence advantages such as motor dynamic balancing.
