Technical field

The utility model relates to a kind of motive power outputting apparatus, relates in particular to a kind of motor.

Background technology

Motor mainly comprises lid, is positioned at the stator of lid, rotor and is located at epitrochanterian bearing, stator and rotor maintenance certain clearance, and general bearing peripheral hardware has bearing cap.Have now at equipment and the time have many deficiencies, big as air gap in the lid, axiality is low, and assembling is complicated, causes the easy axial endplay of motor rotor, and runnability is poor, the maintenance rate height.

The utility model content

Technical problem to be solved in the utility model is to provide at the above-mentioned state of the art that a kind of axiality height, assembling are simple, the motor of accurate positioning.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: motor, comprise front end housing, rear end cap, rotor, keep the stator of certain intervals and be positioned at the clutch shaft bearing of aforementioned rotor front end and second bearing of rear end with rotor, front end housing is connected with rear end cap, it is characterized in that described front end housing is provided with stairstepping first positioning spigot that supplies the clutch shaft bearing installing and locating and stairstepping second positioning spigot that supplies the stator installing and locating, and described rear end cap is provided with stairstepping the 4th positioning spigot of locating for second Bearing Installation and stairstepping the 3rd positioning spigot that supplies the stator installing and locating.

Strengthen water-proof function, be convenient to underwater operation, described clutch shaft bearing front end also is provided with the reinforced seal part, and accordingly, described front end housing also is provided with stairstepping the 5th positioning spigot for reinforced seal part installing and locating.

Further, also be provided with the convex pad that prevents the axial displacement of reinforced seal part between described clutch shaft bearing and the reinforced seal part.

Further, the described second bearing rear end also is provided with the corrugated gasket that prevents the rotor axial play.

Further, described stator is interference fit with rear end cap and front end housing and is connected, and rear end cap and front end housing match.

Compared with prior art, advantage of the present utility model is: be equipped with different stairstepping positioning spigots on front end housing and the rear end cap, greatly facilitate assembling, also improved the axiality of each parts, thereby reduced the friction noise of bearing and other matching parts, make motor performance improve, maintenance reduces; Compact overall structure, volume is less; Being provided with of reinforced seal part increased water resistance, is convenient to underwater operation; The design of convex pad and corrugated gasket has prevented the axial displacement and the rotor axial play of reinforced seal part, has further improved the performance of motor.
