Abstract
The utility model discloses a structure for protecting a copper end ring of a high-speed motor rotor, which comprises a rotor guide bar (1), wherein a copper end ring (2) is welded outside the rotor guide bar (1) and is fixed and supported on a rotor pressing ring (3) on a rotor iron core (6), the outer circumferential surface and the outer end surface of the copper end ring (2) are hooped by a protective ring, and the protective ring is fixed on the copper end ring (2). The structure disclosed by the utility model conducts protection by hooping the copper end ring with the protective ring, so as to prevent generation of centrifugal expansion deformation under high-speed rotation and avoid vibration and fall-off of the copper end ring and damage of a stator coil; and the protective ring is made of an anti-magnetic steel material, has low heat generation due to eddy flow, and has high material utilization ratio.
Description
Technical field
The utility model relates to the high-speed electric expreess locomotive field, relates in particular to a kind of retaining ring structure of high speed rotor of motor copper end ring.
Background technology
In the high-speed electric expreess locomotive, the rotor in the rotating shaft is provided with rotor bar, and the outer hoop of said rotor bar has the copper end ring, and said copper end ring is supported by rotor pressing ring.Motor is in operation process at a high speed, because centrifugal force can produce expansion, distortion, causes vibration, comes off even damages stator coil.
The utility model content
The utility model technical problem to be solved is to provide a kind of and prevents that high speed rotor of motor copper end ring from expanding, distortion, causes vibration, comes off even damages stator coil.
The technical scheme of the utility model is following: a kind of high speed rotor of motor copper end ring retaining ring structure; Comprise rotor bar (1); The outer copper end ring (2) that is with of said rotor bar (1); This copper end ring (2) is supported by the rotor pressing ring (3) that is fixed on the rotor core (6), and its key is: said copper end ring (2) outer circumference surface and outer face are waled by retaining ring, and this retaining ring is fixed on the copper end ring (2).Through retaining ring the copper end ring is protected, prevented centrifugal dilatancy.
Above-mentioned retaining ring is made up of protection plate (4) and guard ring (5), and said guard ring (5) hot jacket is on copper end ring (2) excircle, and said protection plate (4) hot jacket is in copper end ring (2) outer face, and through being bolted on the copper end ring (2); Said protection plate (4) end face is outward extended, and guard ring (5) is stuck between protection plate (4) and the rotor bar (1).This structure is assembled easily.
Above-mentioned protection plate (4) and guard ring (5) are anti-magnet steel forging.Can magnetic conduction, just can not generate heat, cause distortion.
Beneficial effect: the utility model utilizes retaining ring that the copper end ring is waled and protects, and has prevented under the high speed rotating, produces centrifugal dilatancy; More can not vibrate, come off, damage stator coil; Retaining ring is anti-magnetic steel material simultaneously, and the retaining ring eddy-current heating is little, and stock utilization is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1; A kind of high speed rotor of motor copper end ring retaining ring structure; Form by rotor bar (1), copper end ring (2), protection plate (4) and guard ring (5) etc., the outer copper end ring (2) that is with of said rotor bar (1), this copper end ring (2) is supported by the rotor pressing ring (3) that is fixed on the rotor core (6); Said copper end ring (2) outer circumference surface and outer face are waled by retaining ring, and retaining ring is anti-magnet steel forging.This retaining ring is fixed on the copper end ring (2).Said retaining ring is made up of protection plate (4) and guard ring (5), and said guard ring (5) hot jacket is on copper end ring (2) excircle, and said protection plate (4) hot jacket is in copper end ring (2) outer face, and through being bolted on the copper end ring (2); Said protection plate (4) end face is outward extended, and guard ring (5) is stuck between protection plate (4) and the rotor bar (1).
Although more than combine accompanying drawing that the preferred embodiment of the utility model is described; But the utility model is not limited to above-mentioned embodiment; Above-mentioned embodiment only is schematic rather than determinate, and those of ordinary skill in the art is under the enlightenment of the utility model, under the prerequisite of the utility model aim and claim; Can make multiple similar expression, such conversion all falls within the protection range of the utility model.
