Description
Technical field
The utility model relates to the dismounting of city rail vehicle traction electric machine rotor and packaging technology field, is specifically related to a kind of traction electric machine rotor level and promotes frock.
Background technology
Traction electric machine is the important core parts that city rail vehicle traction applies, and in order to enable traction electric machine normally run, must regularly check traction electric machine.Except changing or except supplementary consumable part, also needing to check whether the function of individual part meets the requirements, traction electric machine must be decomposed maintenance if desired in maintenance process.After traction electric machine housing is disassembled, hanging device is adopted to be disassembled from traction electric machine housing by traction electric machine rotor traction electric machine rotor set bolt.Existing traction electric machine dismantling technology cannot guarantee that traction electric machine rotor keeps level in unloading process, in unloading process, then easily cause rotor tilt, causes stator or rotor surface insulating varnish scratch or come off, the series of problems such as armature spindle bump injury.Therefore requirement for horizontality when lift it in its dismounting and assembling process comparatively strictly, then needs professional standards lifting clamp to carry out dismounting and the assembling of rotor.In addition, city rail vehicle traction electric machine because of manufacturing firm's variety classes various, then cause the traction electric machine rotor shaft diameter of axle there are differences, existing horizontal lifting clamp can not meet the demand of the different diameter of axle.
Utility model content
The traction electric machine rotor existed to solve prior art is dismantled and is easily caused rotor and the technical problem such as the scuffing of stator exterior insulating varnish or rotor shaft bump injury because lifting inclination in assembling process, and the utility model provides a kind of traction electric machine rotor level to promote frock.
The technical scheme that the utility model technical solution problem is taked is as follows:
Traction electric machine rotor level promotes frock, it comprises level and promotes cantilever, axle sleeve, internal tooth casing, fishbolt, hoisting ring, the first guide post and the second guide post, axle sleeve is fixed on the bottom that level promotes cantilever, and hoisting ring is fixed on the top that level promotes cantilever; Internal tooth casing is positioned at axle sleeve, and is fixedly clamped by fishbolt with axle sleeve.
The length of above-mentioned internal tooth casing is identical with the length of axle sleeve, and the dimensional tolerance between the internal diameter of axle sleeve and the external diameter of internal tooth casing is less than or equal to 0.5mm.
Traction electric machine rotor level of the present utility model promotes frock can according to the different traction electric machine rotor diameter of axle and the corresponding internal tooth casing of axle head key tooth specifications design, internal tooth casing is mounted in axle sleeve, undertaken fastening by fishbolt and secure it to the axle head of traction electric machine rotor, rotor axle key tooth and internal tooth casing, by engagement fit, fully guarantee that traction electric machine rotor play does not occur in dismounting and assembling process.Adjustment level promotes the hoisting ring position on cantilever, is adjusted to by clamping screw after level, hoisting ring and level is promoted cantilever and locks, thus effectively guarantee moving horizontally of traction electric machine until traction electric machine rotor.Design the guide post corresponding with traction electric machine rotor installing hole, in dismounting and assembling process, guide post is fixed on traction electric machine stator case and rotor anti-drive end, ensure that traction electric machine rotor does not rotate in unloading process.Effectively ensure that traction electric machine rotor moves back the reliability of unloading and in assembling process by above-mentioned frock, and increase traction electric machine rotor shaft internal tooth casing, ensure that it can apply on different traction electric machine.
The beneficial effects of the utility model are: this frock can ensure the abswolute level state of traction electric machine in dismounting and assembling process, and, according to the motor diameter of axle and the axle head key tooth module of required maintenance, design is applicable to the internal tooth casing of different traction electric machine rotor specification, fully meet construction demand, reduce frock making cost.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model traction electric machine rotor level promotes frock.
Fig. 2 is the structural representation of internal tooth casing in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As depicted in figs. 1 and 2, traction electric machine rotor level of the present utility model promotes frock and comprises level lifting cantilever 1, axle sleeve 2, internal tooth casing 3, fishbolt 4, hoisting ring 5, first guide post 6 and the second guide post 7, axle sleeve 2 is fixed on the bottom that level promotes cantilever 1, and hoisting ring 5 is fixed on the top that level promotes cantilever 1; Internal tooth casing 3 is positioned at axle sleeve 2, and is fixedly clamped by fishbolt 4 with axle sleeve 2.
The utility model traction electric machine rotor level promotes the use procedure of frock: loaded by internal tooth casing 3 in axle sleeve 2, clamped by internal tooth casing 3 with fishbolt 4, guarantees that internal tooth casing 3 can not play; Level is promoted the axial end portion that cantilever 1 is mounted to traction electric machine rotor 9, hanging device suspension hook is mounted to hoisting ring 5 place, with hanging device, level is promoted cantilever 1 slightly to sling, adopt clamping screw hoisting ring 5 to be fixed to level after regulating hoisting ring 5 to make traction electric machine rotor 9 be in level and promote on cantilever 1; After adjustment, level is promoted cantilever 1 to back off from traction electric machine rotor 9; First guide post 6 is mounted in traction electric machine stator case 8, the second guide post 7 is mounted on the non-driven-end bearing end cap of traction electric machine rotor 9; Level is promoted the axial end portion that cantilever 1 reinstalls to traction electric machine rotor 9 after assembling, hanging device suspension hook is filled to hoisting ring 5 place, with hanging device, level is promoted cantilever 1 to sling, by traction electric machine rotor 9 along the first guide post 6, second guide post 7 horizontal direction level slowly movement, complete dismounting and the assembling process of traction electric machine.
The utility model is measured traction electric machine rotor axle key tooth diameter, thus determines the interior diameter of internal tooth casing 3; Key tooth axle between cog back lash to be measured and key number of teeth amount confirms, thus determine the key number of teeth amount that internal tooth casing 3 need make and between cog back lash.In addition, according to the outside dimension of the internal diameter size determination internal tooth casing 3 of axle sleeve 2, tolerance can not be greater than 0.5mm between the two, and the length of internal tooth casing 3 need be consistent with the length of axle sleeve 2.
