Abstract
The utility model relates to a water cooling mechanism of an AC permanent magnetic servomotor which is arranged between a stator core and a stator shell and comprises a ring-shaped cooling shell which is embedded and pressed between the stator core and the stator shell. A winding spiral climbing cooling channel is arranged on one side of the cooling shell close to the stator shell; and the cooling shell on two ends of the channel is provided with ring-shaped seal grooves in which sealing rings which are deformed by means of extrusion between the stator shell and the cooling shell are sleeved. The separately designed cooling shell allows the cooling mechanism to be produced independently, completely breaking away from the production of the motor, thereby the whole motor can not be affected because of the abandonment of the cooling mechanism; and the cooling mechanism adopts high-thermal conducting metallic materials, which guarantees swift heat dispersion.
Description
Technical field
The utility model relates to a kind of water-cooled mechanism, especially relates to a kind of alternating-current permanent-magnet servo motor water-cooled mechanism.
Background technology
At present, middle and small motor both domestic and external does not possess the water-cooled mechanism of shell, because the middle and small motor caloric value is few, heat radiation is not a major issue.Yet for the very high alternating-current permanent-magnet servo motor of moment of torsion density, heat dissipation problem just must not become irrespective problem, and the heat-sinking capability of motor directly has influence on motor and uses and service life.This moment, general air cooling way can not satisfy the heat radiation requirement far away.The recirculated water cooling that is adopted adopts stator mostly in casting process both at home and abroad, enclosure interior casting water flowing structure, this forging type complex process, the casting difficulty is big, percent defective height in the casting process, and winding and the thermal resistance between the cooling water as thermal source in the motor are bigger, influence radiation effect of motor, therefore need fundamentally solve heat dissipation problem in a hurry.
Summary of the invention
The utility model mainly be solve existing in prior technology heat radiation difficulty, radiator structure is complicated, technology difficulty is high, radiating efficiency is low etc. technical problem, and provide that a kind of technology is simple, rapid heat dissipation, simple in structure, alternating-current permanent-magnet servo motor water-cooled mechanism that radiating efficiency is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of alternating-current permanent-magnet servo motor water-cooled mechanism is provided, this water-cooled mechanism is installed between stator core and the stator case, its special feature is: this water-cooled mechanism comprises that an embedding is pressed in the annular cooling housing between stator core and the stator case, be provided with around the ascending cooling water road that spirals near on stator case one side at the cooling housing, on the cooling housing at water channel two ends, be provided with annular seal groove, in seal groove, be inserted in by stator case and push mutually and the sealing ring that is out of shape with the cooling housing.A cooling housing is set as water-cooled mechanism alone; thereby avoided stator case or stator core are cast; avoid causing the discarded of stator because of the error of casting; this technical scheme is separated manufacturing with water-cooled mechanism with motor stator fully; thereby the manufacture process of water-cooled mechanism can not have influence on motor itself fully, and selected seal groove and sealing ring can effectively protect cooling water can not reveal because of sealing inadequately
As preferably, the degree of depth of described cooling water channel is 1/3rd to 2/3rds of cooling housing wall thickness.Proper depth not only can keep the intensity of cooling water pipe, and can guarantee that enough cooling waters pass through cooling bath.
As preferably, described cooling water channel is a rectangular recess.Equally also can use oval-shaped groove.
As preferably, be matched in clearance between described cooling housing and the stator core, use special glue to fill the gap of cooling off between housing and the stator core, be interference fit between described stator case and the cooling housing.Interference fit can make the cooling housing tightly be assemblied in the motor stator.
As preferably, described cooling housing is the high-thermal conductive metal material.The high-thermal conductive metal material as copper, can allow heat be delivered to each part of cooling housing rapidly, takes away heat by the water channel that is embedded in fully in the cooling housing then, has improved radiating efficiency greatly.
Therefore, the utlity model has rational in infrastructure, manufacturing process is simple, cost is low, and characteristics such as wide accommodation especially are the cooling housing of motor stator independent design, make cooling body break away from the manufacturing of motor and independently production fully, thereby can not influence whole motor because of the discarded of cooling body, and cooling body adopts the high-thermal conductive metal material, guarantees heat dispersing rapidly more.In addition, the sealing ring that is cooperated can further protect cooling water can not flow away from possible slit.
