Description
Technical field
The utility model relates to rotary rectifier module on a kind of exciter rotor, is specifically related to a kind of fixture facilitating rotary rectifier module on one-sided dismounting exciter rotor.
Background technology
Motor volume is little, and assemble compact, space availability ratio is high, and the clearance space between exciter rotor and support is limited; On exciter rotor iron core when rotary rectifier module maintenance, dismounting, be blocked near fan side, instrument cannot cross over exciter parts hold-down nut demounting bolt, rotary rectifier module cannot in motor internal dismounting, can only first be dismantled together with rotating shaft by exciter parts and then carry out dismounting, maintenance to rotary rectifier module, this procedure be loaded down with trivial details, and workload is large, very easily damage motor, there is hidden danger of quality.
Rotary rectifier module is passed through bolt, nut and exciter rotor clamping unshakable in one's determination, is fixed, and in the disassembly process of device, nut and exciter rotor punching produce and rub, and easily scratch punching sheet surface; And through long-term High Rotation Speed, between nuts and bolt, there is the possibility loosened.For addressing these problems, need a kind ofly to facilitate one-sided dismounting rotary rectifier module, fixture that reliability is high.
Summary of the invention
The purpose of this utility model is to provide a kind of fixture facilitating rotary rectifier module on one-sided dismounting exciter rotor, the architectural characteristic of device itself is utilized to reach the object of easy accessibility, the utility model intensity is good, processing and manufacturing is simple, stable performance, fitting operation is convenient, structural variability is strong, and do not affect the performance of exciter rotor, be particularly suitable for the motor commonly used in the market.
The utility model is achieved like this, facilitate the fixture of rotary rectifier module on one-sided dismounting exciter rotor, inside is provided with axle pilot hole, wire guide, ventilation hole, fixing hole and rivet hole; It is characterized in that: fixture shape is for circular, and central authorities arrange an axle pilot hole, and side, axle pilot hole left and right is provided with wire guide, and fixture periphery is arranged at intervals with some ventilation holes, fixing hole and rivet hole; Described rivet is fixed by rivet hole and exciter rotor iron core, follows rotating shaft High Rotation Speed; Described fixing hole is screwed hole, by bolt by rotary rectifier module clamping on exciter iron core, guarantee one-sided enforcement assembling, dismounting.
Preferably, described ventilation hole is 12.
Preferably, described fixing hole is 4.
Preferably, described rivet hole is 6.
Preferably, the material that described fixture adopts is cold-rolled steel Q235 material.
Preferably, the effect of the inner tapping of described fixing hole, alternative nut, realizes the operation of single-side mounting bolt maintenance, dismounting rotary rectifier module at motor internal to exciter rotor assembly, avoids the dismounting of the large quantities of parts of motor internal.
The beneficial effects of the utility model are: the dismounting of (1) rotary rectifier module is easy to maintenance; (2) stability and the reliability of spare part assembling is increased; (3) assembly process is simplified; (4) simple to operate, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is assembling schematic diagram of the present utility model.
Fig. 3 is the utility model and exciter rotor riveted joint figure unshakable in one's determination.
In the drawings, 1, axle pilot hole, 2, rivet hole, 3, fixing hole, 4, ventilation hole, 5, wire guide, 6, the utility model fixture, 7, exciter rotor is unshakable in one's determination, 8, rivet, 9, rotary rectifier module.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model is implemented like this, facilitates the fixture of rotary rectifier module on one-sided dismounting exciter rotor, and inside is provided with axle pilot hole 1, wire guide 5, ventilation hole 4, fixing hole 3 and rivet hole 2; It is characterized in that: fixture shape is for circular, and central authorities arrange an axle pilot hole 1, and axle pilot hole about 1 side is provided with wire guide 5, and fixture periphery is arranged at intervals with some ventilation holes 4, fixing hole 3 and rivet hole 2; Described rivet is fixed by rivet hole 2 and exciter rotor unshakable in one's determination 7, follows rotating shaft High Rotation Speed; Described fixing hole 3 is screwed holes, by bolt by rotary rectifier module 9 clamping on exciter iron core 7, guarantee one-sided enforcement assembling, dismounting.
During use, by the axle pilot hole 1 of the utility model fixture 6 and the axle pilot hole of exciter rotor punching concentric, align, then with rivet by 7 clampings unshakable in one's determination to the utility model fixture 6 and exciter rotor, fixing, ensure that repeatedly pressure coefficient and the teeth portion of exciter iron core 7 flick length.An exciter rotor only need install a slice the utility model fixture 6, and rotary rectifier module 9 that end of never installing the utility model fixture 6 to be connected with the pilot hole (for screwed hole) of the utility model fixture 6 by bolt and to be fixed on exciter rotor iron core 7.At motor internal, the utility model fixture 6 and rotating shaft realize interference fit by flat key, and during motor High Rotation Speed, the utility model fixture 6 is High Rotation Speed under the drive of rotating shaft, and rotating shaft remains state synchronized.When maintenance needs dismounting rotary rectifier module, the utility model fixture 6 relies on rotating shaft to fix, holding position is constant, operative employee only needs back end cover for motor to remove, and just can carry out dismounting to the rotary rectifier module 9 on exciter rotor, convenient, fast.
