Abstract
The invention relates to a novel damping ring structure for a synchronous six-stage solid stator. The novel damping ring structure for the synchronous six-stage solid stator is structurally characterized in that a damping ring is in simple connection with the end portion of a pole shoe; the damping ring is simple in structure; obvious and reliable radial displacement limiting effects of the damping ring are obtained. Therefore, the damping ring can avoid being thrown away during the high-speed operating process of a motor rotor and accordingly is particularly applicable to the field of large high-speed motors.
Description
Technical field
This patent relates to a kind of synchronous six grades of solid rotor New Damping ring structures, and particularly pole shoe end is connected with damping ring, the interconnective damping ring structure of damping ring between adjacent pole.
Background technology
The existing synchronous six grades of solid rotor electric machines of domestic electric machine industry, if need the pull-in torque improving motor while the effective stock utilization improving motor as far as possible, just need to increase damping ring on the solid rotor of motor.Conventional structure damping ring structure and electrical machinery pole shoe end are difficult to be connected closely, when electric motor starting under rotor voltage effect easily and pole shoe end discharge, and conventional damping ring structure easily throws away in rotor high-speed rotation.
Summary of the invention
Conventional synchronous six grades of solid rotor damping ring structures have a twice difficult problem: one, damping ring easily and pole shoe end discharge; Two, damping ring easily throws away in rotor High Rotation Speed.The present invention is directed to an above-mentioned twice difficult problem to improve conventional structure damping ring, and propose a kind of pole shoe end and be connected with damping ring, the interconnective novel synchronous of damping ring six grades of solid rotor damping ring structures between adjacent pole.
The technical scheme of this patent is: a kind of synchronous six grades of solid rotor New Damping ring structures, damping ring and electrical machinery pole shoe end are bolted, between damping ring and electrical machinery pole shoe end, cushioning one deck silver pad, to ensure that pole shoe end fully contacts with between damping ring, eliminates discharging gap; Meanwhile, in order to ensure that damping ring can not throw away in rotor high-speed rotation, use two groups of braces to connect between adjacent damping ring, these two groups of braces are positioned at both sides, damping ring side, one, side; Corner cut shape is made in two ends of damping ring, a threaded fixed block through processing is used to be pressed in the corner cut of two damping rings, simultaneously, this fixed block used a screw rod and yoke to link together, the radial displacement of damping ring in rotor high-speed rotation can be limited by this structure, thus, this structure can ensure that damping ring can not throw away in rotor High Rotation Speed.As can be seen from above-mentioned two kinds of technical schemes, this patent can solve two hang-ups of the conventional damping ring structure mentioned in this patent.
The advantage of this patent is:
1 damping ring is connected simply with pole shoe end, just can realize connecting, and can avoid the electric discharge problem between pole shoe and damping ring by means of only bolt;
2 damping ring structures are simple, and the damping ring in this structure only just can realize through punching and milling, brill processing with a block plate, and outward appearance looks it is only one and half curved plates, seems neat and artistic and avoids complicated mounting structure;
3 damping ring radial displacement restrictions are obvious and reliable;
The type damping ring structure comes into operation at our factory, and achieves good effect.
