Abstract
The utility model discloses a connecting structure of a motor rotor and a motor main shaft, which comprises an inner taper sleeve which is arranged on the motor rotor, a locking nut which tightens the inner taper sleeve on the motor main shaft is arranged on the inner taper sleeve and on the rear end of the motor main shaft, and the length of the locking nut is a quarter of to half of that of the inner taper sleeve. Due to the connecting structure of the motor rotor and the motor main shaft, the connection of the motor rotor and the motor shaft is firmer, and the motor rotor and the motor main shaft are easier and more convenient to disassemble.
Description
Technical field
The utility model relates to a kind of connecting structure, the connecting structure of particularly a kind of rotor and electric machine main shaft.
Background technique
Motor must be considered the assembly problem of rotor and electric machine main shaft when design, so the rotor of motor and the connection of electric machine main shaft are the problems that field of motor manufacturing relatively is concerned about always.Traditional rotor installation method is with only adopting interference fit to come reality between rotor and the electric machine main shaft.The shortcoming of this method is: adopt this Placement on the one hand, make that the dismounting of rotor and electric machine main shaft is very inconvenient; On the other hand, adopt the Placement of the interference fit of this rotor and electric machine main shaft that installer's technical experience is had relatively high expectations.For the use of reality has brought very big inconvenience.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and the connecting structure of a kind of rotor and electric machine main shaft is provided.Adopt the utility model to make being connected of rotor and electric machine main shaft more fastening, and make the dismounting of rotor and electric machine main shaft become to be more prone to, convenient.
For achieving the above object, the technical solution adopted in the utility model is: the connecting structure of rotor and electric machine main shaft, it is characterized in that: comprise the inner conical drogue that is arranged on the rotor, on the described inner conical drogue and the rear end that is positioned at electric machine main shaft is provided with inner conical drogue is fastened on locking nut on the electric machine main shaft, and the length of described locking nut accounts for 1/4th to 1/2nd of inner conical drogue length.
The above-mentioned rotor and the connecting structure of electric machine main shaft, the length of described locking nut accounts for 1/3rd of inner conical drogue length.
The above-mentioned rotor and the connecting structure of electric machine main shaft are provided with packing ring between described locking nut and the inner conical drogue.
The utility model compared with prior art has the following advantages: when the utility model is installed, earlier rotor is contained in earlier on the inner conical drogue, the interior vertebra that will load onto rotor again is sleeved on the electric machine main shaft, uses locking nut screwing again.Adopt the utility model to make being connected of rotor and electric machine main shaft more fastening, and make the dismounting of rotor and electric machine main shaft become to be more prone to, convenient.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
A kind of rotor as shown in Figure 1 and the connecting structure of electric machine main shaft, comprise the inner conical drogue 6 that is arranged on the rotor 5, on the described the inner conical drogue 6 and rear end that is positioned at electric machine main shaft 10 is provided with inner conical drogue 6 is fastened on locking nut 7 on the electric machine main shaft 10, and the length of described locking nut 7 accounts for 1/4th to 1/2nd of inner conical drogue 6 length.Preferred way is that the length of described locking nut 7 accounts for 1/3rd of inner conical drogue 6 length.Be provided with packing ring between described locking nut 7 and the inner conical drogue 6.The front end and back end of described motor housing 2 is separately installed with protecgulum 1 and bonnet 4, described locking nut 7 is connected with encoder 8, described encoder 8 is connected with the driver of outside, described motor housing inwall is provided with and rotor 5 corresponding stators 3, be used for startup to electric machine main shaft 10, be provided with sealing gasket 9 between described protecgulum 1 and the electric machine main shaft 10, strengthened the sealing of whole motor.
When the utility model is installed, earlier rotor 5 is contained in earlier on the inner conical drogue 6, the interior vertebra cover 6 that to load onto rotor 5 again is contained on the electric machine main shaft 10, tighten with locking nut 7 again, the length of described locking nut 7 accounts for 1/4th to two/for the moment of inner conical drogue 6 length, and described inner conical drogue 6 can effectively be fastened on the rotor 5, when the length of locking nut 7 accounts for three/for the moment of inner conical drogue 6 length, neither influence the proper functioning of rotor 5, play best fastening effect again.Adopt the utility model to make rotor 5 more fastening with being connected of electric machine main shaft 10, and make the dismounting of rotor 5 and electric machine main shaft 10 become to be more prone to, convenient.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
