The after-sale service of the drive chain of all permanent-magnetic variable-frequency compressors on existing market is all more complicated, it is necessary first to Horizontal positioned driving motor is detached from complete machine, and horizontal positioned driving motor is hung to be vertical using special tooling, then according to It is secondary to remove end cap, bearing, stator, rotor respectively, it finally just can be carried out after-sale service, after-sale service caused to need more people Power, after service cost increase, and the seeervice cycle that some clients need is longer, and customer satisfaction is caused to reduce, serious also Lead to client's long-term shutdowns.
Therefore a kind of new permanent-magnetic variable-frequency driven compressor chain structure form is researched and developed, is become with meeting efficiently after-sale service It is particularly important.
Summary of the invention
To solve the above problems, the present invention provides the connection structure of a kind of compressor and motor, facilitate motor shaft and compression The fast quick-detach of machine head axis meets efficiently after-sale service demand.
To achieve the above object, the connection structure of compressor of the invention and motor, head axis and drive including compressor The motor of the head axis rotation is moved, the motor includes motor shaft, stator, rotor and shell, and the stator is fixedly mounted on The inner surface of the shell, the rotor are fixed on the motor shaft, the motor further include front end flange, bearing block and after End cap, the front end flange and bearing block are separately fixed at the both ends of the shell, and the rear end cap is fixed on the bearing block On;Centre bore is offered on the front end flange, the motor shaft passes through the centre bore;Between the head axis and motor shaft It is provided with tapered sleeve, the tapered sleeve is connected by key with the head axis, and one end of the motor shaft is offered matches with the tapered sleeve The cone tank of conjunction, the tapered sleeve are placed in the cone tank, and the other end of the motor shaft is connected by bearing and the bearing block It connects;Axially penetrating through for the motor shaft is provided with a stud, and one end of the stud is connect with the head axle thread, the other end Equipped with locking nut, the end abutment of the locking nut and the motor shaft.
Preferably, the gap between the stator and rotor is greater than between the motor shaft and the centre bore of front end flange Spacing.
Preferably, the bearing and the bearing block use transition fit.
Preferably, bolt is fixed on the both ends of the shell respectively for the front end flange and bearing block.
Preferably, the rear end cap is bolted on the bearing block.
The connection structure of compressor and motor of the invention, using motor shaft and helical-lobe compressor head axial cone set connection shape The bearing block of formula and the design of special motor front end flange and rear end designs, so that the connection structure of compressor and motor Disassembly and after-sale service become efficient and convenient, are improving after-sale service efficiency, while reducing after service cost, also significantly Meet the demand of client.
Detailed description of the invention
Referring to attached drawing, the disclosure be will be apparent.It is to be appreciated that these attached drawings are only illustrative, not It is drawn to scale to be also not intended to limit the scope of the present invention.In figure:
Fig. 1 is the schematic diagram of the connection structure of compressor and motor of the invention.
Specific embodiment
Explain a specific embodiment of the invention in detail with reference to the accompanying drawings.
As shown in Figure 1, the connection structure of compressor and motor of the invention, head axis 1 and driving institute including compressor The motor of the rotation of head axis 1 is stated, the motor includes motor shaft 7, stator 8, rotor 10, front end flange 5, shell 9, bearing block 12 With rear end cap 16, the stator 8 is fixedly mounted on the inner surface of the shell 9, and connection type can use tight fit, described Rotor 10 is fixed on the motor shaft 7;Centre bore 51 is offered on the front end flange 5, the motor shaft 7 passes through in described Heart hole 51;The front end flange 5 and bearing block 12 are fixed on the both ends of the shell 9, the rear end by bolt 6,12 respectively Lid 16 is fixed on the bearing block 12 by bolt 15;Tapered sleeve 2, the cone are provided between the head axis 1 and motor shaft 7 Set 2 is connect with the head axis 1 by key 4, and one end of the motor shaft 7 offers the cone tank with the tapered sleeve 2 cooperation, institute It states tapered sleeve 2 to be placed in the cone tank, the other end of the motor shaft 7 is connect by bearing 14 with the bearing block 13, described Bearing 14 and the bearing block 13 use transition fit, when needing to remove motor shaft 7, use the bearing 14 of transition fit can be with Easily removed from bearing block 13.Axially penetrating through for the motor shaft 7 is provided with a stud 11, one end of the stud 11 It is threadedly coupled with the head axis 1, the other end is equipped with locking nut 15, the end of the locking nut 15 and the motor shaft 7 It abuts, by rotating the locking nut 15, to the cone tank of the motor shaft 7 and the tapered sleeve 2 be compressed, the torsion of motor Square passes to head axis 1 by the frictional force between motor shaft 7 and tapered sleeve 2, and can be increased by increasing the pretightning force of stud 11 The peak torque that power-up arbor 7 can transmit.
Gap between the stator 8 and rotor 10 is greater than between the motor shaft 7 and the centre bore 51 of front end flange 5 Spacing, when motor shaft 7 and the disengagement of tapered sleeve 2, the centre bore 51 of front end flange 5 can hold motor shaft 7, prevent rotor 10 and determine Son 8 sweeps thorax, destroys the insulating layer of winding.
Front end flange 5 is bolted on counter flange 3.Counter flange 3 is arranged between compressor and motor.
The rear end cap 16 is fixed on the bearing block 13 by bolt 17, plays the role of sealed motor inner cavity, together When can also play the role of axially position to the bearing 14.
When needing to dismantle motor, motor shaft 7 is dismantled using drawing horse after only rear end cap 16 need to be dismantled.Unclamp lock Tight nut 15, withstands stud 11 for the mandril for drawing horse, and motor shaft 7 slightly moves to the right a distance at this time, and tapered sleeve 2 can be with electricity Arbor 7 disengages, and the centre bore of front end flange 5 can hold in time motor shaft 7, to realize the quick of motor shaft 7 and head axis 1 It disengages.Fast quick-detach of the motor shaft 7 in horizontal situation is realized, after-sale service efficiency is improved, saves the time, reduce After service cost greatly meets the demand of client.
As described above, exemplary embodiments of the invention are described in detail referring to attached drawing.It should Solution, the present invention, which is not intended to, makes these details constitute limiting the scope of the invention.Without departing substantially from according to this hair In the case where bright spirit and scope, can the structure and features to exemplary embodiments carry out equivalent or similar change Become, these changes will also be fallen in protection scope determined by claims appended hereto.
