Abstract
The invention discloses a high-heat-dissipation explosion-proof three-phase asynchronous motor. A stator iron core is installed in a motor base. A rotor matched with the stator iron core is installed in the stator iron core. End rings are respectively fixed on two ends of the rotor. A plurality of rotor fan blades are arranged along the peripheral directions of the two end rings. The widths, along the peripheral direction, of the rotor fan blades are forwards or backwards gradually reduced. Rib plates are arranged in grooves formed in the outer periphery of the stator iron core, and the thickness of each rib plate is equal to the depth of each groove. The outer diameter of the stator iron core is equal to the diameter of a cylindrical cavity of the motor base.

Summary of the invention
The present invention is that the lower problem affecting explosion-proof performance of radiating efficiency solving fire-proof motor in prior art proposes a kind of heat dissipation type high explosion-proof three-phase asynchronous motor.The technical solution used in the present invention is: a kind of heat dissipation type high explosion-proof three-phase asynchronous motor, comprise the support of the cylindrical cavity of inwall, in the front end of support, direction is provided with front end housing and fore bearing enclosing cover successively from back to front, in the rear end of support, direction is provided with rear end cap and rear bearing enclosing cover successively from front to back, in support, stator core is installed, the rotor matched with stator core is installed in stator core, all end ring is fixed with at the two ends of rotor, two end ring are along the circumferential direction provided with multiple rotor fan blade, described rotor fan blade width is along the circumferential direction from end ring position forward direction or rear to diminishing gradually, gusset is provided with in groove on stator core excircle, the thickness of described gusset equals the degree of depth of groove, the overall diameter of described stator core equals the diameter of support cylindrical cavity.
Further, the edge of described front end housing and rear end cap is arcwall face, and is equipped with radiating ribs on the front and back of the front and back of front end housing, rear end cap.
Further, between fore bearing enclosing cover and bearing, between rear bearing enclosing cover and bearing, spring sealed circle is all installed.
Further, the contact-making surface of fore bearing enclosing cover and front end housing is provided with diameter 1 ~ 3 annular groove not etc., the contact-making surface of rear bearing enclosing cover and rear end cap is provided with diameter 1 ~ 3 annular groove not etc., in annular groove, rubber seal is installed.
A kind of heat dissipation type high explosion-proof three-phase asynchronous motor is achieved based on above improvement, the advantage of this motor is: by (1) lower thickness by original plane end cap, then its edge is set to arcwall face and welds radiating ribs in interior outside thus accelerate motor interior heat and the extraneous speed exchanged; (2) change fastening piece structure original for stator core into gusset and the outer surface of stator core is processed make it fully to contact with support cylindrical cavity thus add the heat transferring contact area of stator core and support; (3) on the end ring of two ends of rotor, be welded with multiple rotor fan blade accelerate the flowing of motor interior heat thus accelerate heat radiation; (4) spring sealed circle and rubber seal are set on bearing end cover, the V-type ring protective capacities solved on original bearing of motor is poor, moist dust enters into motor interior easily by V-type ring with the contact-making surface of bearing, lubricating grease can be made for a long time to lose efficacy, the problem that explosion suppresion surface damages.
