Abstract
The utility model discloses a fixed structure of rotor core retaining ring, including installing at epaxial rotor core, rotor tooth pressure board, rotor retaining ring, balancing stand and retaining ring in proper order, the rotor retaining ring comprises two semi -cyclic linkages, and the balancing stand sets up tang, tang internal diameter and rotor retaining ring major diameter fit. The utility model has the advantages that: the retaining ring opening part need not weld, and an influence is not had in the antitrochanter dynamic balance, and the dismouting of being convenient for, has avoided the problem of quality, life -span and the dynamic balance of the shape direct influence rotor of welding quality's quality and intensity and solder joint.
Description
Technical field
The utility model patent relates to field of motor manufacturing, specifically the fixed structure of rotor core back-up ring.
Background technology
Rotor is the quality of the critical component in motor, rotor workmanship, directly has influence on quality and the life-span of motor manufacturing.The fixing general of rotor core adopts two semi-cyclic linkages as back-up ring, by two semi-cyclic linkage opening parts and the spot welding of rotor tooth pressing plate firm, little for slowspeed machine impact, and for high-speed electric expreess locomotive, dynamic balance accuracy requires high, the quality of welding quality and intensity, directly affect the quality of rotor, life-span and dynamic balancing.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one can not need welded structure, and concrete technical scheme is as follows:
A kind of fixed structure of rotor core back-up ring, comprise the rotor core be arranged on successively on axle, rotor tooth pressing plate, a rotor's check ring, balancing stand and back-up ring, described a rotor's check ring is made up of two semi-cyclic linkages, and balancing stand arranges seam, seam internal diameter and a rotor's check ring major diameter fit.
The utility model has the advantages that: back-up ring opening part does not need welding, and on rotor dynamic balancing without impact, and be convenient to dismounting, the shape of the quality and intensity and solder joint that avoid welding quality directly affects the quality of rotor, life-span and dynamically balanced problem.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is a rotor's check ring structural representation.
Embodiment
The utility model is illustrated below in conjunction with accompanying drawing, as Fig. 1, shown in Fig. 2, the utility model comprises the rotor core 1 be arranged on successively on axle 6, rotor tooth pressing plate 2, a rotor's check ring 3, balancing stand 4 and back-up ring 5, as shown in Figure 2, described a rotor's check ring 3 is made up of two semi-cyclic linkages, be made up of two semi-cyclic linkages, general by annular retaining ring, separate from centre by Numerical control cutting, gap is very little, balancing stand 4 processes a seam 41, seam 41 internal diameter is consistent with a rotor's check ring 3 external diameter nominal size, select a matched in clearance size, balancing stand 4 hot charging is on 6 axles, and coordinate with a rotor's check ring 3, play the effect of fixed rotor back-up ring 3, such a rotor's check ring 3 opening part does not need welding, on rotor dynamic balancing without impact, and be convenient to dismounting.The form of balancing stand 4 has a variety of, and Fig. 1 is only wherein a kind of form.Back-up ring 5 is for preventing balancing stand 4 axial endplay.
Claims (3)
1. the fixed structure of a rotor core back-up ring, it is characterized in that: comprise the rotor core be arranged on successively on axle, rotor tooth pressing plate, a rotor's check ring, balancing stand and back-up ring, described a rotor's check ring is made up of two semi-cyclic linkages, and balancing stand arranges seam, seam internal diameter and a rotor's check ring major diameter fit.
2. fixed structure according to claim 1, is characterized in that: seam internal diameter and a rotor's check ring external diameter are matched in clearance.
