Abstract
The utility model relates to a prepositioning device convenient for motor rotor into-shaft assembly. The prepositioning device comprises a motor shaft, a dummy shaft which is disposed opposite to the motor shaft, and a shaft alignment sleeve which sleeves an end portion of the motor shaft and an end portion of the dummy shaft at the same time. A positioning keyway is made in the shaft alignment sleeve. A motor shaft key and a dummy shaft key are disposed on the motor shaft and the dummy shaft respectively. The shaft alignment sleeve of the prepositioning device is specially designed to cooperate with the dummy shaft, and aims at ensuring that the dummy shaft and the motor shaft are on the same axis, and therefore, the rotor can be enabled to be precisely conveyed to the motor shaft through the dummy shaft, and the into-shaft installation of the rotor becomes convenient.
Description
Technical field
The utility model belongs to rotor field, relates to rotor press-mounting, and especially a kind of rotor of being convenient to enters the device for pre-positioning that axle assembles.
Background technology
Normally a kind of plant equipment that is mechanical kinetic energy by electric energy conversion of motor, motor generally comprises motor casing, is fixed on the stator of motor casing inside and the rotor with respect to the rotatable support of stator.Stator is arranged on the inside of motor casing, and rotor rotates in stator, and the motor shaft being connected with rotor is supported on shell by pair of bearings conventionally.
When rotor and armature spindle enter axle assembling, owing to being interference fit between armature spindle and rotor, need larger strength just can make rotor enter axle, in prior art, both assemblings are adopt manual type or press-fit by pressing machine, but because rotor can not well be fixed, the operation that enters axle assembling is very inconvenient, and production efficiency is low.
For above-mentioned deficiency, need to explore a kind of energy secondary rotor and enter the device that axle assembles, coordinate pressing machine to reduce the difficulty into axle assembling, enhance productivity.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of rotor of being convenient to enter the device for pre-positioning that axle assembles.
The technical scheme that the utility model technical solution problem adopts is:
A kind of rotor of being convenient to enters the device for pre-positioning that axle assembles, comprise motor shaft, the dummy shaft of installation relative to motor shaft, and be set with simultaneously motor shaft end and dummy shaft end to shaft sleeve, in to shaft sleeve, be shaped with positioning spline, motor axle key and dummy shaft key are housed respectively on motor shaft and dummy shaft.
And described dummy shaft one end penetrates in shaft sleeve, the both sides of the other end extend outward respectively flanging, and flanging is embedded in pilot sleeve, and in pilot sleeve, the coaxial setting-in slide block in the end of dummy shaft, is coaxially fixedly mounted with spring at the other end of slide block.
And at the outer rim coaxial package dummy shaft seat of dummy shaft, dummy shaft seat and fairlead bucket are coaxially fixedly mounted with.
Advantage of the present utility model and good effect are:
1, this device for pre-positioning is to coordinate dummy shaft and custom-designed to shaft sleeve, its objective is and guarantees that dummy shaft and motor shaft can be on same axis, so just can make rotor be transferred on motor shaft by dummy shaft accurately, and what be convenient to rotor enters axle installation.
2, this device for pre-positioning modern design, has changed original dummy shaft and has entered the artificial propelling movement mode of axle, not only saves time but also laborsaving, and can also guarantee the axiality of rotor and motor shaft.
Accompanying drawing explanation
Fig. 1 is middle axial section of the present utility model
Embodiment:
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
Be convenient to the device for pre-positioning that rotor enters axle assembling, comprise motor shaft 10, the dummy shaft 6 of installation relative to motor shaft, and be set with simultaneously motor shaft end and dummy shaft end to shaft sleeve 7.In to shaft sleeve, be shaped with positioning spline 8, motor axle key 9 and dummy shaft key 5 are housed respectively on motor shaft and dummy shaft.
Described dummy shaft one end penetrates in shaft sleeve, and the both sides of the other end extend outward respectively flanging, and flanging is embedded in pilot sleeve 1.In pilot sleeve, the left end of dummy shaft coaxially installs slide block 3, is coaxially fixedly mounted with spring 2 at the left end middle part of slide block.Dummy shaft by slide block and spring can be in pilot sleeve stretching motion.At the left end outer rim coaxial package dummy shaft seat 4 of dummy shaft, dummy shaft seat and fairlead bucket are coaxially fixedly mounted with.
The operation principle of this device: when use, first use to shaft sleeve by dummy shaft together with motor shaft sleeve, effect be aim at location, to guarantee that dummy shaft and motor shaft can be on same axis.Shaft sleeve is taken off, rotor is enclosed within on dummy shaft, dummy shaft to motor shaft feeding, is touching dummy shaft retraction after motor shaft with rotor again, and rotor is also pushed on motor shaft simultaneously, and the axle that enters that completes rotor assembles.
Claims (3)
1. be convenient to rotor and enter the device for pre-positioning of axle assembling for one kind, it is characterized in that: comprise motor shaft, the dummy shaft of installation relative to motor shaft, and be set with simultaneously motor shaft end and dummy shaft end to shaft sleeve, in to shaft sleeve, be shaped with positioning spline, motor axle key and dummy shaft key are housed respectively on motor shaft and dummy shaft.
2. the rotor of being convenient to according to claim 1 enters the device for pre-positioning that axle assembles, it is characterized in that: described dummy shaft one end penetrates in shaft sleeve, the both sides of the other end extend outward respectively flanging, flanging is embedded in pilot sleeve, in pilot sleeve, the coaxial setting-in slide block in the end of dummy shaft, is coaxially fixedly mounted with spring at the other end of slide block.
3. the rotor of being convenient to according to claim 1 enters the device for pre-positioning that axle assembles, and it is characterized in that: at the outer rim coaxial package dummy shaft seat of dummy shaft, dummy shaft seat and fairlead bucket are coaxially fixedly mounted with.
