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.
