Abstract
The invention discloses a connecting structure of a motor spindle and a motor rotor, which comprises an inner cone sleeve which is arranged on the motor rotor; the left end of the inner cone sleeve is provided with a plurality of oil holes; the oil holes extend into the contact surface of the inner cone sleeve and the motor spindle; the oil holes are internal threaded holes; bolts are installed in the oil holes; and the oil holes form an angle of 15 DEG to 45 DEG with the motor spindle. According to the invention, the disassembly of the motor rotor is convenient; and the connecting structure has a simple structure and is convenient in utilization.
Description
Technical field
The present invention relates to a kind of draw bail, the draw bail of particularly a kind of electric machine main shaft and rotor.
Background technology
The connection of rotor and motor shaft is the problem that field of motor manufacturing relatively is concerned about always.Traditional motor stator installation method is with adopting interference fit to come reality between rotor and the motor shaft.The shortcoming of this method is: 1, dismounting is difficult for.2, consumes energy.3, installer's technical experience is had relatively high expectations.For the use of reality brings very big inconvenience.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, the draw bail of a kind of electric machine main shaft and rotor is provided.The present invention can make things convenient for the dismounting of rotor, and it is simple in structure, and is easy to use.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: the draw bail of a kind of electric machine main shaft and rotor is characterized in that: comprise the inner conical drogue that is arranged on the rotor, and the left end of said inner conical drogue is provided with a plurality of oilholes; Said oilhole extend into the contact-making surface of inner conical drogue and electric machine main shaft; Said oilhole is an internal thread hole, in the said oilhole screw is installed, and said oilhole and electric machine main shaft are 15 °～45 ° angles.
The above-mentioned a kind of electric machine main shaft and the draw bail of rotor, the quantity of said oilhole are eight.
The above-mentioned a kind of electric machine main shaft and the draw bail of rotor, said oilhole and electric machine main shaft are 30 ° of angles.
The present invention compared with prior art has the following advantages: the present invention can make things convenient for the dismounting of rotor, and it is simple in structure, and is easy to use, and for the application of reality brings great convenience, said oilhole is an internal thread hole, in the said oilhole screw is installed.Through screw is set oilhole is sealed, get into wherein to prevent dust and other impurities, and then influence the dismounting of rotor.Said oilhole 10 is 15 °～45 ° angles with electric machine main shaft 1; During dismounting, oil is poured into oilhole 10, when the angle of oilhole 10 and electric machine main shaft 1 is 15 °～45 °; The oily contact-making surface that enters into inner conical drogue 9 and electric machine main shaft 1 that can be very fast; Very fast the completion dismantled, and wherein when the angle of oilhole 10 and electric machine main shaft 1 was 30 °, effect was best.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.

Embodiment
A kind of electric machine main shaft as shown in Figure 1 and the draw bail of rotor; Comprise the inner conical drogue 9 that is arranged on the rotor 8; And the left end of said inner conical drogue 9 is provided with a plurality of oilholes 10, and said oilhole 10 extend into the contact-making surface of inner conical drogue 9 and electric machine main shaft 1, and said oilhole 10 is an internal thread hole; In the said oilhole 10 screw 11 is installed, said oilhole 10 is 15 °～45 ° angles with electric machine main shaft 1.Preferred way is that the quantity of said oilhole 10 is eight.Another kind of preferred way is that said oilhole 10 is 30 ° of angles with electric machine main shaft 1.
Electric machine main shaft 1 is installed in the shell 12, and the front and back end of said shell 12 is separately installed with front-end bearing pedestal 3 and rear bearing block 6, on the said front-end bearing pedestal 3 fore bearing 2 is installed; On the said rear bearing 5 rear bearing 5 is installed, through fore bearing 2 and rear bearing 5 electric machine main shaft 1 is located, the right-hand member of rotor 8 is equipped with encoder 7; Said encoder 7 links with external driver, is used for the startup to electric machine main shaft, and vertebra put in rotor 8 was contained in earlier; Be provided with the stator module 4 corresponding with rotor 8 at shell 12 inwalls, refill on electric machine main shaft 1, interior vertebra cover endoporus has certain tapering; Left end has oilhole 10, when rotor 8 need be pulled down, can squeeze into hydraulic oil from the oilhole 10 of interior vertebra cover; Under the effect of the pressure of oil, interior vertebra cover just can be pulled down from electric machine main shaft 1.
The present invention can make things convenient for the dismounting of rotor 8, and it is simple in structure, and is easy to use, and for the application of reality brings great convenience, said oilhole 10 is an internal thread hole, in the said oilhole 10 screw 11 is installed.Seal through 11 pairs of oilholes 10 of screw are set, get into wherein to prevent dust and other impurities, and then influence the dismounting of rotor 8; Said oilhole 10 is 15 °～45 ° angles with electric machine main shaft 1, during dismounting, oil is poured into oilhole 10; When the angle of oilhole 10 and electric machine main shaft 1 is 15 °～45 °, the contact-making surface that enters into inner conical drogue 9 and electric machine main shaft 1 that oil can be very fast, very fast the completion dismantled; Wherein when the angle of oilhole 10 and electric machine main shaft 1 was 30 °, effect was best.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any restriction, every technical spirit all still belongs in the protection range of technical scheme of the present invention any simple modification, change and equivalent structure transformation that above embodiment did according to the present invention.
