Description

A kind of split type alternating current generator

Technical field

The utility model belongs to technical field of motors, in particular to a kind of split type alternating current generator.

Background technique

Traditional motor product is all made of parts such as electric machine casing, stator, rotor and bearings.This motor product body Product is big, not easy to disassemble after the completion of Product Assembly, so that the maintainability of product is poor.So needing to design a kind of small in size, convenience The motor product of disassembly.

Utility model content

In order to solve the above-mentioned technical problem, the purpose of the utility model is to provide a kind of split type alternating current generators.The motor Structure be it is split type, it is small in size, and each part is easy to install and remove, therefore in motor product failure, facilitate maintenance.

To achieve the goals above, the utility model adopts the following technical solution: a kind of split type alternating current generator, the fission Formula alternating current generator includes rear end cap, rotor, stator, bearing and drive end bearing bracket；The rotor includes rotor core and shaft, described The front and rear ends of stator are respectively equipped with drive end bearing bracket and rear end cap, and rotor core, which is fitted in shaft, forms rotor, and rotor axial is set In stator interior, the both ends of shaft are pressed with bearing respectively, and bearing is respectively placed in first bearing room and the drive end bearing bracket of rear end cap In second bearing room, guarantee the concentricity of installation.

Further, the front end face of the drive end bearing bracket is equipped with annular groove, and annular groove is connected to second bearing room, turns The front end of axis is pierced by second bearing room.

Further, the rear end cap, rotor, stator, bearing and drive end bearing bracket are coaxial.

Compared with prior art, the utility model has the following beneficial effects: the split type alternating current generator of the utility model Because not having motor housing, the stator outer diameter size of motor is the maximum outside diameter of motor, therefore motor volume is small, and it is empty to save installation Between.The structure of the motor be it is split type, each part is easy to install and remove, therefore in motor product failure, facilitates maintenance.

Specific embodiment

With reference to embodiment and attached drawing is described in further detail the utility model.

Referring to Fig.1, a kind of split type alternating current generator, the split type alternating current generator include rear end cap 1, rotor 2, stator 3, axis Hold 4 and drive end bearing bracket 5；The rotor 2 includes rotor core 2-1 and shaft 2-2, is respectively equipped in the front and rear ends of the stator 3 Drive end bearing bracket 5 and rear end cap 1, rotor core 2-1 are fitted in composition rotor 2, rotor 2 on shaft 2-2 and are axially located inside stator 3, The both ends of shaft 2-2 are pressed with bearing 4 respectively, bearing 4 be respectively placed in rear end cap 1 first bearing room 1-1 and drive end bearing bracket 5 In two bearing chamber 5-1, guarantee the concentricity of installation.

The front end face of the drive end bearing bracket 5 is equipped with annular groove 5-2, and annular groove 5-2 is connected to second bearing room 5-1, The front end of shaft 2-2 is pierced by second bearing room 5-1.

The rear end cap 1, rotor 2, stator 3, bearing 4 and drive end bearing bracket 5 are coaxial.

The rear end cap 1, rotor 2, stator 3 and drive end bearing bracket 5 of the utility model be all it is self-existent, stator 3 is mounted directly Into superior system, motor does not have outer housing, and the stator outer diameter size of motor is the maximum outside diameter of motor, therefore motor volume It is small, save installation space.The structure of the motor be it is split type, each part is easy to install and remove, therefore in motor product failure, Facilitate maintenance.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
