Abstract
The utility model discloses a fan-type ventilating trough plate of a generator rotor, which comprises a motor rotating shaft (1) and a plurality of motor stamped steels (2) arranged on the motor rotating shaft (1). The fan-type ventilating trough plate is characterized in that a rotor ventilating trough plate (3) arranged between each two motor stamped steels (2) is equipped with a plurality of tooth-shaped openings (7), each tooth-shaped opening (7) is equipped with an inserting slot (4), end fingers (5) are connected onto the tooth-shaped openings (7) through inserting strips (6) matching with the inserting slot (4), and the amount of the end fingers (5) is 2-10. The fan-type ventilating trough plate of a generator rotor has the advantages of simple structure, convenient use, easy mounting and dismounting, preventing overhigh temperature inside a motor, prolonging service life of the motor, further increasing operation reliability of the motor and the like.
Description
Technical field:
The utility model relates to the inner cooling structure of a kind of generator, especially a kind of motor case inner air that promotes circulates, the heat that stator and rotor cores is produced takes to outside the casing by air/water cooler quickly, prevent that temperature is too high in the motor, improve the generator amature fan-type ventilation channel plate of running reliability of motor.
Background technology:
Existing generator is realized the purpose of generator internal cooling by air/water cooler, and described air/water cooler is installed in the motor top, and dock mutually the import/export of cooler and motor, forms the circulatory system of a sealing.The hot-air that produces when cooler moves motor is delivered in the cooler and is cooled off, so that the temperature of motor internal various piece is in the suitable scope all the time, to guarantee the normal operation and the work of motor.But development along with electromechanics trade, the specification and the power of generator are increasing, temperature requirement to its enclosure interior is also more and more higher, common cooler can not satisfy this demand, therefore need a kind of generator inside that can be arranged on, can play the radiator structure of auxiliary heat dissipation function.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, easy to use, installing/dismounting is easy to, can prevent that temperature is too high in the motor, prolong motor useful life, further improve the generator amature fan-type ventilation channel plate of motor operational reliability.
Technical solution of the present utility model is: a kind of generator amature fan-type ventilation channel plate, comprise machine shaft 1 and setting a plurality of motor stampings 2 thereon, it is characterized in that: be arranged on two rotor ventilation frids 3 between the motor stamping 2 and offer a plurality of dentation openings 7, dentation opening 7 is provided with slot 4, and tooth pressure sheet 5 is connected on the dentation opening 7 by the cutting 6 that matches with slot 4.
Described tooth pressure sheet 5 is a plurality of, and concrete quantity is 2-10.
The utility model is compared with prior art, has following advantage:
Simple in structure, install, dismounting is very convenient, and with low cost, can in the motor operation, promote the circulation of air that it is inner, reach the purpose that reduces the motor internal temperature, temperature remains in the set point of temperature in the motor thereby make, to guarantee the normal operation of motor; Possess extensive market prospects, can more easily apply in electromechanics trade.

Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5: a kind of generator amature fan-type ventilation channel plate, comprise machine shaft 1 and setting a plurality of motor stampings 2 thereon, between per two motor stampings 2, be provided with rotor ventilation frid 3, on rotor ventilation frid 3, offer a plurality of dentation openings 7, dentation opening 7 is provided with slot 4, be provided with the cutting 6 of projection in a side of tooth pressure sheet 5, size matches with slot 4, tooth pressure sheet 5 by transplant a cutting 6 and slot 4 be connected on the dentation opening 7; Described tooth pressure sheet 5 is a plurality of, and its quantity is 2-10, and concrete quantity can be selected according to actual needs, to reach best radiating effect.
The course of work of the generator amature fan-type ventilation channel plate of the utility model embodiment is as follows: the tooth pressure sheet 5 that is plugged on the dentation opening 7 axially protrudes in rotor ventilation frid 3, when machine operation, rotor ventilation frid 3 just can rotate under the drive of machine shaft 1 thereupon, outstanding tooth pressure sheet 3 just can force the air in the generator to carry out flowing fast, the air that temperature is higher is transported in the cooler, and impel the lower air of temperature quick, enter in the motor in large quantities, reach the purpose that reduces temperature in the motor, further satisfy the temperature environment requirement of motor operation, guaranteed motor operate as normal for a long time.
Claims (2)
1, a kind of generator amature fan-type ventilation channel plate, comprise machine shaft (1) and setting a plurality of motor stampings (2) thereon, it is characterized in that: be arranged on the rotor ventilation frid (3) between two motor stampings (2) and offer a plurality of dentation openings (7), dentation opening (7) is provided with slot (4), and tooth pressure sheet (5) is connected on the dentation opening (7) by the cutting (6) that matches with slot (4).
