Abstract
The invention discloses a rotor end ring protector, which comprises a hexagonal-head bolt, a stop washer, a retaining ring, an end ring, a guiding bar, an arc key, a rotor core, a shaft and a key; the rotor core is sleeved on the shaft; the guiding bar is inserted into the rotor core; the end ring is welded at the end of the guiding bar; the retaining ring is fixed with the end ring through the hexagonal-head bolt and the stop washer; the arc key is inserted into a key slot at the end of the rotor core on the shaft; and the key is inserted into a key slot on the retaining ring on the shaft. The rotor end ring protector has the advantages of simple and compact structure and obvious effect; and moreover, the end ring is protected by adding the retaining ring under the condition of ensuring the safety and reliability of a motor and not changing a structural material.
Description
Technical field
The present invention relates to protect the device of rotor end ring, be specifically related to be used for the rotor protective device of high-speed three-phase asynchronous electric machine.
Background technology
Therefore the rated speed of motor often is limited by the limit speed of bearing, can not design too highly during design, has restricted the expansion in market.The rising of motor speed; involve a lot of aspects; as the protection of the winding degree of axle, rotor end ring and stress etc.; if wherein rotor end ring is not taked certain measure protection; the fail safe of general high-speed three-phase asynchronous electric machine just is difficult to be protected; therefore, need effectively protect, satisfy its performance requirement rotor end ring.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of rotor end ring protector is provided, under the condition that guarantees motor safety and reliability, utilize effective measures, motor rotor end ring is protected.
Technical scheme of the present invention is as follows:
A kind of rotor end ring protector; comprise hex bolts, stop washer, retaining ring, end ring, sliver, arc key, rotor core, axle and key; described rotor core is enclosed within on the axle; sliver is inserted in the rotor core; the end of sliver is welded with end ring; retaining ring is fixed by hex bolts and stop washer and end ring, and the arc key is filled in the keyway that is positioned at the rotor core end on the axle, and key is filled in the keyway that is positioned at the retaining ring place on the axle.
Its further technical scheme is: described end ring cylindrical has a step, and described retaining ring is enclosed within on the step of end ring.
And its further technical scheme is: be evenly equipped with the identical ventilation hole of size on the described retaining ring.
Useful technique effect of the present invention is:
The present invention is simple in structure, compact, and action effect is obvious; Under the situation that does not change structural material, under the condition that guarantees motor safety and reliability,, reach the purpose of protection end ring by increasing a grommet device, avoid the sliver that when centrifugal force is big, fractures, thereby reach the requirement safe in utilization of pot motor.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a retaining ring structural representation of the present invention.
Fig. 3 is the cutaway view along A-A among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes hex bolts 1, stop washer 2, retaining ring 3, end ring 4, sliver 5, arc key 6, rotor core 7, axle 8 and key 9.Rotor core 7 is enclosed within on the axle 8, and sliver 5 is inserted in the rotor core 7, and the end of sliver 5 is welded with end ring 4, and retaining ring 3 is fixing with end ring 4 by hex bolts 1 and stop washer 2.Arc key 6 is filled in the keyway that is positioned at rotor core 7 ends on the axle 8, is used for fixing rotor core 7.Key 9 is filled in the keyway that is positioned at retaining ring 3 places on the axle 8, with round fixedly (see figure 3) in the retaining ring 3.End ring 4 cylindricals have a step 10, and retaining ring 3 is enclosed within on the step 10 of end ring 4.
As shown in Figure 2, be evenly equipped with the identical ventilation hole 11 of size on the retaining ring 3.
Installation process is as follows: at first that retaining ring 3 is fixing with end ring 4 by hex bolts 1, stop washer 2, sliver 5 injects in the rotor core 7 successively, and sliver 5 is welded on end ring 4 internal recess with the HlAgCu80-5 silver solder, pass through hot cover process, rotor core 7 is heated to 220 ℃ and keep constant temperature 3h, is inserted in axle 8 then, and fill in the keyway on spools 8 with arc key 6, fixed rotor iron core 7, it is fixing with circle in the retaining ring 3 to fill in key 9.
End ring 4 inside parts of the present invention and sliver 5 weld together, Outboard Sections is connected with retaining ring 3 by hex bolts 1, stop washer 2, in the outside be subjected to balanced power, the centrifugal force that is produced when avoiding not having retaining ring 3 sliver 5 that fractures simultaneously, thereby reach the requirement safe in utilization of pot motor.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
