Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-5, the utility model relates to an outdoor rainproof type explosion-proof machine, including frame 1 and shell 2, its characterized in that: frame 1 top is provided with shell 2, shell 2 surface is provided with the rectangle piece, shell 2 top is provided with outlet box 3, the terminal surface is provided with front end housing 4 before shell 2, front end housing 4 central authorities are provided with preceding enclosing cover 41 of bearing, the inside first bearing 42 that is provided with of enclosing cover 41 before the bearing, shell 2 rear end face is provided with rear end housing 5, rear end housing 5 central authorities are provided with enclosing cover 51 behind the bearing, the inside second bearing 53 that is provided with of enclosing cover 51 behind the bearing, second bearing 53 central authorities are provided with clamp plate 52, be provided with pivot 6 between first bearing 42 and the second bearing 53, be provided with cast aluminium rotor 7 on the pivot 6, cast aluminium rotor 7 outside is provided with stator core 8, stator core 8 and outlet box 3 are connected with power and external control ware electricity, and receive external control ware.
The outer surface top of the shell 2 is provided with a suspension ring 21, which is convenient for suspension.
