Abstract
The invention provides a rotor tooth compacting device for an asynchronous motor. The rotor tooth compacting device comprises a tooth compacting plate, reinforcing ribs and a round steel ring, wherein the tooth compacting plate is circular, teeth are uniformly distributed at the edge of the circle, and a round hole is formed in the center of the circle; the round steel ring is welded in the round hole in the center of the tooth compacting plate, and keeps concentric with the tooth compacting plate; and a plurality of reinforcing ribs are welded between the tooth compacting plate and the round steel ring respectively, and are uniformly distributed on the circumferences of the tooth compacting plate and the round steel ring. The tooth compacting plate provided by the invention can guarantee the equipartition; the tooth rigidity of the compacting device is good; the deformation under pressure is small; the tooth part of the motor can be compacted; the problem of poor compaction of a high-speed motor and a tractor motor is solved especially in fields with a high reliability requirement; and work efficiency and product quality can be improved.
Description
Technical field
The present invention relates to the tight apparatus structure of asynchronous machine rotor tooth pressure, the rotor tooth hold down gag structure of especially big-and-middle-sized high speed AC induction motor, asynchronous machine that reliability requirement is high.
Background technology
Current domestic asynchronous machine rotor tooth pressure adopts punching press end plate, tooth pressure bar, three part combinations of trim ring to compress conventionally.Above-mentioned technology still can be implemented for short iron core, slowspeed machine; But for long iron core, high-speed electric expreess locomotive, said structure does not often reach specification requirement, causes iron core not press tightly, and tooth rises too large, cause motor electromagnetic noise large.
Summary of the invention
The invention provides a kind of asynchronous machine rotor tooth hold down gag, solve big-and-middle-sized asynchronous machine rotor tooth and rise, the problem not pressing tightly, can improve production work efficiency, Improving The Quality of Products.
Technical scheme of the present invention is as follows:
A tooth hold down gag, comprises tooth pressure strip, reinforcement and round steel ring; Described tooth pressure strip is rounded, and circular edge is evenly equipped with tooth, and circular center offers circular hole; Described round steel boxing is connected on the circular hole place at tooth pressure strip center, and keeps concentric with tooth pressure strip; A plurality of reinforcements are welded on respectively between tooth pressure strip and round steel ring, and are uniformly distributed on the circumference of tooth pressure strip and round steel ring.
Useful technique effect of the present invention is:
Tooth pressure strip of the present invention can guarantee equal calibration, and the tooth good rigidly of hold down gag is out of shape little under pressure, can clamping motor tooth portion, especially in the high field of reliability requirement, make high-speed electric expreess locomotive, traction electric machine not have the problem not pressing tightly, can improve work efficiency and product quality.
The aspect that the present invention is additional and advantage will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1, Fig. 2 have provided a kind of embodiment of the present invention.As shown in Figure 1 and Figure 2, the present invention is a kind of tooth portion hold down gag structure.Comprise a tooth pressure strip 1, a plurality of reinforcement 2 and a round steel ring 3.Tooth pressure strip 1 is processed on numerical control device that edge is evenly equipped with tooth, round-meshed circle is offered in center.Round steel ring 3 is welded on tooth pressure strip 1 center hole place, guarantees that round steel ring 3 is concentric with tooth pressure strip 1.A plurality of reinforcements 2 are evenly distributed on the circumference of tooth pressure strip 1, and one end of reinforcement 2 is welded on tooth pressure strip 1, and the other end of reinforcement 2 is welded on round steel ring 3.During use, two the present invention are placed on respectively to the two ends of motor stamping, one end is fixed, and one end pressurization, completes rotor tooth pressure.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
