| 摘要 |
The invention relates to an asynchronous motor with antiexplosive construction, applicable to driving the equipments and installations in the petrochemical industry, boring, coal mining industry, etc.The motor comprises a stator core (1), pressed between two pipe cylinders (2, 3) provided with bevels for fixing the end-shields (4) equipped with ball-bearings (5) which are fastened with ball-bearing covers (6), mounted on the end-shields (4) with the screws (7). The rotor subassembly (8) provided with a fan (9) covered by the hood (10) fixed with the screws (11) to the elbow pieces (12) welded to the cylinder (3) rotates on the two ball-bearings (5) . The terminal box is made of a square-shaped pipe (13) welded to the cylinder (2, 3), covered with a plate (14) welded to a pipe (13). The terminal box cover (15) is fastened by screws to the terminal box screwed in the plugs (16) welded on the plate (14).The stator winding (17) is supplied by means of a feeder cable (18) passing through a packing gland (19) welded to the square-shaped pipe (13), a rubber ring (20) tightened with a bolt screw (21), provided with a clip (22) fastened with two inbus screws (23) to the bolt screw (21), the clip (22) clamping the feeder cable (18), preventing the loosening of the packing gland.
