Abstract
The utility model relates to the motor manufacturing technology and discloses a squirrel-cage motor rotor balancing device. The device comprises a balance disc. An outer end surface of the balance disc is provided with a circular groove. A plurality of balancing blocks are installed in the circular groove. The circular groove is coaxial with a motor rotation shaft. A lower bottom edge of a radial cross section of the circular groove is greater than an upper opening edge. The balancing blocks are arc blocks which form sliding fit with the circular groove. A center position of an outer end surface of the balancing blocks is provided with a threaded hole. The threaded hole is a through hole. A top tight screw is installed in the threaded hole. By using the device, dynamic balance of the motor can be rapidly adjusted during motor assembling; operation is simple, usage is convenient and the device is safe and firm; the device has good operability during implementation.
Description
Technical field
The utility model relates to motor manufacturing technology, particularly a kind of squirrel-cage motor rotor balancer.
Background technology
In ideal conditions, rotor rotation is the same with not rotating the pressure that bearing is produced, and such revolving body is the revolving body of balance.But, the error that the material of rotor is inhomogeneous, produce in rotor key, coupling and processing and assembling, while even design, just have the many factors such as asymmetrical geometry, make rotor when rotated, the centrifugal intertia force that on it, each small particle produces can not be cancelled out each other, centrifugal intertia force is applied on other parts by bearing, cause vibration, produce noise, accelerate bearing wear, shorten part life, when serious, can damage incidents.
Utility model content
The purpose of this utility model is to provide a kind of squirrel-cage motor rotor balancer, use this device can be in the time that motor assembles the dynamic balancing of quick adjustment motor, and simple to operate, easy to use, safe firm, have in force good operability.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme to be reached.
A kind of squirrel-cage motor rotor balancer, is characterized in that, comprise balancing frame, the outer face of described balancing frame is provided with annular groove, and multiple balance weights are installed in described annular groove; Described annular groove is coaxial with machine shaft, and the bottom of described annular groove radial section is greater than upper shed limit, and described balance weight is the arc piece being slidably matched with described annular groove; The center position of the outer face of described balance weight is provided with screwed hole, and described screwed hole is through hole, in described screwed hole, is provided with and holds out against screw.
Feature of the present utility model and further improvement are:
Wherein one section of straight hole being provided with for balance weight is installed of described annular groove.
Described annular groove is dovetail groove.
Described annular groove radial section is trapezoidal.
Described balancing frame is that steel plate processes.
Squirrel-cage motor rotor balancer of the present utility model, adopt tight fit to be installed on rotor field spider, and integrally welded with rotor field spider, balance weight is installed in the annular groove on balancing frame by straight hole, and reach the effect of balance according to the quality of the size adjustment balance weight of different aequums and the angle that is positioned at balancing frame circumference, finally tighten and hold out against screw balance weight is stuck in the annular groove on balancing frame, and welding.This device can be in the time that motor assembles the dynamic balancing of quick adjustment motor, and simple to operate, easy to use, safe firm, have in force good operability.

Embodiment
With reference to Fig. 1, for the structural representation of rotor of a kind of squirrel-cage motor rotor balancer of the present utility model is installed; This device comprises balancing frame 1, and the outer face of balancing frame 1 is provided with annular groove, and multiple balance weights 2 are installed in annular groove; Annular groove is coaxial with machine shaft 5, and the bottom of annular groove radial section is greater than upper shed limit, and balance weight 2 is the arc piece being slidably matched with annular groove; The center position of the outer face of balance weight 2 is provided with screwed hole, and screwed hole is through hole, is provided with and holds out against screw 3 in screwed hole.Wherein one section of straight hole being provided with for balance weight 2 is installed of annular groove.
Annular groove can be designed as the groove that radial section is swallow-tail form, and also can be designed to radial section is trapezoidal groove.
Balancing frame 1 processes for steel plate.
This device is installed on rotor field spider 4, adopt close-fitting to merge with rotor field spider 4 integrally welded, balance weight 2 is arranged in the annular groove on balancing frame 1 by straight hole, in the time that assembling, motor reaches the effect of balance according to the quality of the size adjustment balance weight 2 of different aequums and the angle that is positioned at balancing frame 1 circumference, finally tighten and hold out against screw 3 balance weight is stuck in the annular groove on balancing frame 1, and firm welding.This device can be in the time that motor assembles the dynamic balancing of quick adjustment motor, and simple to operate, easy to use, safe firm, have in force good operability.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art, under the enlightenment of specification, in the case of not departing from the scope that the utility model claim protects, can also make a variety of forms, and these all belong to the row of the utility model protection.
