Above clutch shaft bearing, jump ring be located at the top of packing ring and is stuck in inside annular slot, annular slot including bottom surface, upper side and
Downside, upper side and downside are all planes.When assembling motor, due to first mounting gasket, packing ring easily sticks into neck, leads
Cause can not be all sticked into annular slot with more great strength jump rings, and motor can not be installed in place, while firmly extruding jump ring
Annular slot is caused to crumble, grain raising, bearing can not exit from rotating shaft during so as to cause to tear open motor, and bearing loss increases.
The content of the invention：
The purpose of this utility model is to provide a kind of external rotor electric machine, can effectively solve prior art middle washer and first install
The problem of neck the inside causes jump ring more difficult or can not sticked into annular slot, and motor can not be installed in place.
The purpose of this utility model is achieved by following technical proposals.
A kind of external rotor electric machine, including stator module, rotor assembly and rotating shaft, rotor assembly are connected with rotating shaft installation, turned
Sub-component is sleeved on the outside of stator module, and axially spaced-apart is provided with clutch shaft bearing and second bearing, rotating shaft inside stator module
Installation is supported on clutch shaft bearing and second bearing, and rotating shaft is provided with annular slot, and packing ring and jump ring are arranged in rotating shaft, packing ring
Above clutch shaft bearing, jump ring is located at the top of packing ring and is stuck in inside annular slot, it is characterised in that：Described annular
Neck includes bottom surface, upper side and downside, and described downside is inclined plane.
Downside described above is inclined plane or arc surface.
Upper side described above is plane.
Packing ring described above is taper elastic washer.
Packing ring described above is two.
Jump ring described above is two.
The utility model compared with prior art, has the effect that：
1) a kind of external rotor electric machine described in the utility model, including stator module, rotor assembly and rotating shaft, rotor assembly
Install and connect with rotating shaft, rotor assembly is sleeved on the outside of stator module, and axially spaced-apart is provided with first axle inside stator module
Hold and second bearing, rotating shaft installation are supported on clutch shaft bearing and second bearing, rotating shaft is provided with annular slot, packing ring and jump ring
In rotating shaft, packing ring is located above clutch shaft bearing, and jump ring is located at the top of packing ring and is stuck in inside annular slot, described
Annular slot include bottom surface, upper side and downside, described downside is inclined plane, when motor assembles, when packing ring sticks into
When inside annular slot, by the extruded gasket that exerted a force to jump ring, packing ring exits annular slot along the downside of annular slot, had
Being sticked into beneficial to jump ring in annular slot, motor assembles in place, effectively reduces task difficulty, improves operating efficiency, and
Rotating shaft can be effectively protected, solves the problems, such as grain raising, is advantageous to motor and tears machine open, reduce bearing loss, reduce cost.
2) downside of annular slot is designed to inclined plane or arc surface, can not have to very big to jump ring application
Power, it is possible to allow packing ring to exit annular slot, jump ring is sticked into annular slot, and motor assembles in place, can more effectively reduce work
Industry difficulty, improve operating efficiency.
3) upper side of annular slot is designed to plane, and upper side can effectively stop that jump ring is exited in annular slot.

Embodiment：
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
As shown in Figures 1 to 6, the present embodiment is a kind of external rotor electric machine, including stator module 1, rotor assembly 2 and rotating shaft
3, rotor assembly 2 and rotating shaft 3 installation connect, and rotor assembly 2 is sleeved on the outside of stator module 1, between the inside axial direction of stator module 1
Every being provided with clutch shaft bearing 11 and second bearing 12, the installation of rotating shaft 3 is supported on clutch shaft bearing 11 and second bearing 12, rotating shaft 3
Annular slot 31 is provided with, packing ring 4 and jump ring 5 are arranged in rotating shaft 3, and packing ring 4 is located at the top of clutch shaft bearing 11, and jump ring 5 is located at
The top of packing ring 4 and it is stuck in the inside of annular slot 31, it is characterised in that：Described annular slot 31 includes bottom surface 311, upside
Face 312 and downside 313, described downside 313 is inclined plane.
Described downside 313 is inclined plane or arc surface.
Described upper side 312 is plane.
