Abstract
The utility model relates to an integral rotor tooth clamping ring for a motor, which comprises an annular tooth clamping ring body sheathed on a motor rotating shaft, wherein the outer edge of the annular tooth clamping ring body is provided with a plurality of integral clamping teeth which are respectively corresponding to sheet teeth of a rotor core. The utility model adapts the rotor sheet, and the clamping ring teeth (clamping teeth) can effectively contact the sheet teeth; and under the action of the clamping force of the iron core, various positions of the sheet are uniformly stressed, thereby well solving the problem of tooth rising and effectively solving the potential safety hazard of the vent spacer. The utility model enhances the operational reliability of the motor, has the advantages of low cost, high operational reliability and the like, and is easy to operate.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of tooth pressure circle, and especially a kind of motor is with unitary rotor tooth pressure circle.
Background technology
As the part of motor magnetic circuit, rotor core by the punching silicon-steel of 0.5 millimeters thick, be overrided to form, the punching cylindrical dashes has equally distributed hole, is used for settling rotor bar.Because there is burr inevitably in the silicon steel sheet that forms of punching out, stacking factor unshakable in one's determination is reduced, bring the core tooth part tooth problem that rises.
At present, solve the tooth problem that rises with rotor ventilation frid and not toothed trim ring usually, like Fig. 1; Rotor ventilation groove 3 comprises rotor end plates and welding vent segment above that; Because the circle of the not toothed trim ring 2 cylindrical specific impulse sheet bottom lands in this structure is little, can only act on the yoke portion of rotor core 4 through the power of trim ring, and vent segment rigidity itself is not high yet; Thereby be difficult to fundamentally to solve the tooth problem that rises; Particularly, often cause vent segment under centrifugal action, to throw out, scratch stator core coil for high-speed electric expreess locomotive.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of motor with unitary rotor tooth pressure circle, and it can solve the high rotating speed copper bar rotor core tooth problem that rises, and motor is under high rotating speed, rotor integral rigidity and integrity problem.
The purpose of the utility model solves through following technical scheme:
This motor comprises the annular tooth trim ring body that is set on the machine shaft with unitary rotor tooth pressure circle, on the outer rim of annular tooth trim ring body, is provided with a plurality of integral types and presses tooth, and said a plurality of pressure teeth are corresponding with rotor-core lamination tooth location respectively.
Above-mentioned annular tooth trim ring body and pressure tooth and said rotor core on it are fitted on the machine shaft, and locate annular tooth pressure circle body through core key, make respectively to press tooth to align with each punching tooth portion of rotor core respectively.
Further, on said annular tooth trim ring body, offer ventilation hole.
The unitary rotor tooth pressure circle of the utility model; Itself and rotor punching adapt; Trim ring tooth portion (pressure tooth) can contact with punching tooth portion effectively, under the effect of iron core pressure mounting power, makes each position of punching stressed evenly; Well solve the problem that tooth rises, solved the potential safety hazard of vent segment effectively.The utility model has improved running reliability of motor.The utlity model has easy to operate, cost is low, advantage such as reliable.
Description of drawings
Fig. 1 is the employing rotor ventilation frid and the not toothed trim ring structure chart of prior art;
Fig. 2 is the structure chart of the utility model;
Fig. 3 is the installation front view of the utility model;
Fig. 4 is the axial cutaway view of the utility model after installing.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 2; This motor is with unitary rotor tooth pressure circle; Comprise the annular tooth trim ring body 5.1 that is set on the machine shaft (1), on the outer rim of annular tooth trim ring body 5.1, be provided with a plurality of integral types and press teeth 5.2 that a plurality of pressure teeth 5.2 are corresponding with rotor core 4 punching tooth portions 4.1 positions respectively.On said annular tooth trim ring body 5.1, offer ventilation hole 7 in addition.
Referring to Fig. 3 and Fig. 4, said annular tooth trim ring body 5.1 and the pressure tooth on it 5.2 are fitted on the machine shaft 1 with rotor core 4, and locate annular tooth pressure circle body 5.1 through core key, make respectively to press tooth 5.2 to align with rotor core 4 each punching tooth portion 4.1 respectively.When mounted, press tooth 5.2 and punching tooth portion 4.1 to adapt, guarantee certain facewidth, satisfy the requirement of the dress pressure of rotor core 4, reduce core tooth part and flick, reduce the motor iron loss, raise the efficiency.Ventilation hole 7 on the annular tooth trim ring body 5.1 should align with the axial ventilation hole of rotor core 4, through rotor arc key 6 rotor core 4 is compressed then, makes dress pressure act on rotor core 4 tooth portions and yoke portion equably.
In sum, after the utility model is installed, the slot part of penetrate rotor copper bar 7, the tooth portion that compresses rotor core 4 forms an integral type press mounting structure with the yoke portion that is installed on the machine shaft 1 with the axial hole that is used to ventilate.
