Abstract
The utility model relates to a new damping ring structure of a synchronous six-grade solid rotor. The damping ring structure is characterized in that the connection between a damping ring and an end part of a pole shoe is simple, the structure of the damping ring is simple, the limiting effect of the radial displacement of the damping ring is obvious and reliable, the damping ring will not be thrown away in a high-speed operating process of a motor rotor, and the damping ring structure is especially applicable to the field of large-scale 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 to improve the pull-in torque of motor in improving effective stock utilization of motor as far as possible, just need to increase damping ring on the solid rotor of motor.Conventional structure damping ring structure is difficult to be connected closely with electrical machinery pole shoe end, easy and pole shoe end electric discharge under rotor voltage effect in the time of electric motor starting, and conventional damping ring structure easily throws away in rotor High Rotation Speed process.
Summary of the invention
Conventional synchronous six grades of solid rotor damping ring structures have a twice difficult problem: one, damping ring easily discharges with pole shoe end; Two, damping ring easily throws away in rotor High Rotation Speed.The utility model improves conventional structure damping ring for an above-mentioned twice difficult problem, and has proposed a kind of pole shoe end and be connected with damping ring, six grades of solid rotor damping ring structures of the interconnective novel synchronous of damping ring 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, cushioning one deck silver pad between damping ring and electrical machinery pole shoe end, fully contacts between pole shoe end and damping ring guaranteeing, has eliminated discharging gap; Meanwhile, in order to guarantee that damping ring can not throw away in rotor High Rotation Speed process, 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 of a side; Corner cut shape is made in two ends of damping ring, use a threaded fixed block through processing to be pressed in the corner cut of two damping rings, simultaneously, this fixed block used a screw rod and yoke to link together, can limit the radial displacement of damping ring in rotor High Rotation Speed process by this structure, thereby this structure can guarantee that damping ring can not throw away in rotor High Rotation Speed.From above-mentioned two kinds of technical schemes, can find out, this patent can solve two hang-ups of the conventional damping ring structure of mentioning in this patent.
The advantage of this patent is:
1 damping ring is connected simply with pole shoe end, only just can realize connection by bolt, and can avoid the electric discharge problem between pole shoe and damping ring;
2 damping rings are simple in structure, and the damping ring in this structure only just can be realized through punching and milling, brill processing with a block plate, and outward appearance looks it is only one and half curved plates, seem neat and artistic and avoided 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 has obtained good effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent.
Fig. 2 is the structure vertical view of this patent.
Embodiment
Below in conjunction with accompanying drawing 1 and accompanying drawing 2, this patent is further illustrated.
As shown in Figure 1, item (1) is motor stator core, item (2) is rotating pole-piece, (3) damping ring is connected with item (2) rotating pole-piece by (4) bolt, the silver-colored pad of cushioning item (9) as shown in Figure 2 between pole shoe end and damping ring.Shape is as shown in Figure 1 made in damping ring end, between the damping ring of adjacent two magnetic poles, use as shown in Figure 2 (5) brace to connect, between brace and damping ring, connect together with (11) nut by (10) bolt.Between adjacent two damping rings, there is as depicted in figs. 1 and 2 (12) fixed block to be pressed on the corner cut of two damping rings, simultaneously, together with this fixed block is threaded connection with item (7) bolt as shown in Figure 1, full in bolt upper end and the weldering of fixed block screwed hole position.On item (7) bolt, there is a pair of nut that can lock---(6), together with item (12) fixed block, damping ring end corner cut is clamped.Item (7) bolt is connected with yoke, and junction is locked with (13) locking nut.
