Abstract
The invention relates to a rotor tooth pressure plate structure with a rotor balancing function, which comprises a rotor tooth pressure plate and is characterized in that the rotor tooth pressure plate is provided with a U-shaped groove; a screw thread through hole is formed inside the U-shaped groove and in the peripheral direction of the rotor tooth pressure plate; a balancing bolt and a gasket are arranged in the screw thread through hole. According to the rotor tooth pressure plate structure with the rotor balancing function, which is disclosed by the invention, the rotor tooth pressure plate and a rotor balancing disc are combined into one part, the rotor structure is simplified and the inner space of a motor is saved. The trouble of additionally arranging the balancing disc is also omitted, the rotor structure is simplified is simplified and the rotor tooth pressure plate structure is simple to manufacture and is convenient to install.
Description
Technical field
The present invention relates to a kind of rotor tooth pressing plate with rotor balancing function, belong to motor manufacturing technology field.
Background technology
Y2 low-pressure high-power motor and Y2 high-voltage compact motor, rotor is substantially all with internal fan and ventilating duct.And when Y2 low-pressure high-power motor and Y2 high-voltage compact motor adopt copper bar rotor, because of rotor end ring unlike casting aluminium rotor end ring with balance columns, cannot directly in rotor core, carry out rotor dynamic balancing.Common way is that a balancing frame is respectively installed at rotor core two ends again, and balancing frame circumferencial direction is beaten many screwed holes, balancing bolt and pad is installed for rotor dynamic balancing on screwed hole.Like this, it is complicated that rotor structure just seems, and take again motor internal space.So the rotor structure of will trying every possible means now to simplify, saves motor internal space as far as possible.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rotor tooth pressure plate structure with rotor balancing function is provided, rotor tooth pressing plate and rotor balancing disc are integrally combined, simplified rotor structure, saved motor internal space; Reach the object of rotor balancing.
According to technical scheme provided by the invention, a kind of rotor tooth pressure plate structure with rotor balancing function comprises rotor tooth pressing plate, feature is, described rotor tooth pressing plate is provided with U-shaped groove, on the inner rotator tooth support circumferencial direction of U-shaped groove, be provided with tapped through hole, balancing bolt and pad are housed in described tapped through hole.
Advantage of the present invention is: the rotor tooth pressing plate of band rotor balancing function of the present invention, rotor tooth pressing plate and rotor balancing disc are merged into parts, and simplified rotor structure, saved motor internal space.This saves the trouble of other dress balancing frame, has simplified rotor structure, makes simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is tooth pressboard structure schematic diagram of the present invention.
Fig. 2 is that rotor is loaded onto the use view after tooth support.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing.
As shown in Figure 1, the rotor tooth pressing plate with rotor balancing function of the present invention, comprises rotor tooth pressing plate 1.
First by the quantity of rotor bar and size, on rotor tooth pressing plate 1, be provided with U-shaped groove 3, in the inner circumferential direction of U-shaped groove 3, be provided with tapped through hole 2, balancing bolt 4 and pad 5 are housed in described tapped through hole 2, reach the object of rotor balancing.The outside dimension of noting ventilating duct while beating screwed hole, the outside dimension of ventilating duct is avoided in the distribution of screwed hole as much as possible, prevents when balancing bolt and pad are installed and ventilating duct interference.The size of screwed hole and quantity are determined according to actual needs.Finally by balancing bolt and pad, rotor tooth pressing plate 1 and rotor balancing disc are tightened to one.
Claims (2)
