Abstract

The utility model relates to a motor stator, in particular to a propping drive motor stator core which comprises a front plunger ring and a back plunger ring at the two ends. Stator punching sheets which are folded and pressed together are arranged between the two plunger rings. The periphery passing through the stator punching sheets and the plunger rings is provided with at least one connecting screw rod. The surrounding sides of the stator punching sheets are provided with at least one groove, and the groove is fixed with a pulling plate with the two ends being welded on the front plunger ring and the back plunger ring. The utility model uses a plurality of compact and novel whole laminated stand structures for the first time; therefore, the utility model not only reduces the volume of the motor and saves steel and iron materials, but also ensures the mechanical property of the motor.

Description

The top-drive motor stator core
Technical field
The utility model relates to a kind of motor stator, is specially a kind of top-drive motor stator core.
Background technology
The support of general common electric machine and iron core partly are separately, support is mainly as the mechanical support of whole motor, be used for fixing accessories such as end cap simultaneously, also have other effects such as the wind path of the ventilating system that constitutes motor or air compartment in some cases, do not play the effect of magnetic conduction magnetic circuit; Stator core mainly plays the magnetic conduction magnetic circuit and embeds winding.Support and stator core are adopted hot jacket to cooperate and are fitted together.Along with the development of design of electrical motor and manufacturing technology, applying working condition is more and more abominable.Electric machine stand has developed into the full laminated frame that is formed by silicon steel plate stacking, is the mechanical support of whole motor, plays the effect of magnetic conduction magnetic circuit again.The full laminated frame of alternating current machine has following advantage: (1) has improved the heat conductivility of support, can reduce the temperature rise of stator winding; (2) thickness of minimizing support reduces motor volume, weight saving.Now in some industries, exploit as oil drilling, the oil drilling device will be used top-drive device, the nucleus equipment of top-drive device is a top-drive motor, top-drive motor directly directly drives drilling tool from the top, have compact conformation, advantage that the high lock of tool drilling of transmission efficiency is few, the report that full laminated frame is applied to top-drive motor is not also arranged at present.
Summary of the invention
The utility model provides a kind of top-drive motor stator core.
The utility model is realized by following technical scheme, a kind of top-drive motor stator core, the preceding trim ring and the back trim ring that comprise two ends, be provided with the stator punching that overlaps together between two trim rings, the periphery that passes stator punching and trim ring is provided with at least one connecting screw rod, stator punching week, side had at least one groove, be welded with in the groove two ends be welded on before arm-tie on trim ring and the back trim ring.Connecting screw rod is four or eight, and groove is four or eight.
Stator punching is a rectangle.Connecting screw rod is distributed in four jiaos of stator punching of rectangle, and groove is uniformly distributed on four limits of stator punching of rectangle.Have ventilation hole on the stator punching.
Assembling process is at first stator punching, front and back trim ring to be overlapped together by laminating frock.Locate by circle in the trim ring when laminating.This four part compresses with hydraulic press laminating on the frock back, location, guarantees that the stacking factor of lamination is not less than 0.97, and is by connecting screw rod (eight high strength double threaded screws) that the lamination and the trim ring that compress is fastening simultaneously, and keep-ups pressure.Under pressure state, (do not remove and laminate frock and double threaded screw), embed (8) arm-tie (material is 20 steel plate Q235-A) in the lamination slot after, and lamination, trim ring after will compressing with arm-tie weld together.Can guarantee the overall mechanical performance of stator core like this, be fit to the instructions for use that operating mode and other similar operating modes are driven in the top, oil field.
For preventing to weld back weldment distortion, after welding was finished, support carried out the destressing Ageing Treatment with frock.If welding deformation amount is bigger, can be according to actual conditions, restrained deformation takes appropriate measure to.Such as reducing welding capacity, increasing welding times and the staggered welding of weld seam etc.
When reality is used, in order to reduce the suffered stress of main weld (weld seams at front and back trim ring and arm-tie two ends), prevent that main weld lost efficacy, adopt eight M24 high strength double threaded screws that pass lamination that stator core and front and rear cover are linked into an integrated entity first, the screw rod two ends are fastening with the M24 nut.
In order to strengthen the heat-sinking capability of support, in the limited space of stator punching, four groups of totally 36 ventilation holes have been increased.
The utility model has used multinomial succinct, novel full laminated frame structure first on top-drive motor.When guaranteeing the electromechanics performance, reduce the volume of motor, saved ferrous materials.Greatly reduce the processing capacity of support.Reduced the stator winding temperature rise, increased motor and moved stability.

Embodiment
As 1,2 signals of accompanying drawing, a kind of top-drive motor stator core, the preceding trim ring 1 and the back trim ring 4 that comprise two ends, be provided with the stator punching 3 that overlaps together between two trim rings, the periphery that passes stator punching 3 and two trim rings is provided with at least one connecting screw rod 6, stator punching 3 all sides have at least one groove 7, be welded with in the groove 7 two ends be welded on before arm-tie 2 on trim ring 1 and the back trim ring 4.Connecting screw rod 6 is four or eight, and groove 7 is four or eight.
Stator punching 3 is a rectangle.Adopt the punching of squarish full wafer as stator punching, made full use of the leftover pieces of silicon steel sheet, waste of material seldom; The stator punching surrounding has 8 grooves, is used for embedding arm-tie 2, guarantees that the stator core outer surface is smooth attractive in appearance.Connecting screw rod 6 is distributed in four jiaos of stator punching of rectangle, and groove 7 is uniformly distributed on four limits of stator punching 3 of rectangle.Have ventilation hole 5 on the stator punching 3.
Connecting screw rod 6 is a double threaded screw.
