Abstract
The invention discloses a kind of ventilated motor, including drive end bearing bracket, housing, rear end cap；Drive end bearing bracket includes front end cap body, flange, some gussets；Bearing hole is provided with the middle part of the cap body of front end；Flange is relative with front end cap body axially spaced-apart, by being distributed on some link of boards of front end cap body bearing hole surrounding together；Gusset and front end cap body right side, flange form cooling air channel between left side；Wind scooper is axially connected on rear end cap inner side end；Gusset is arc；Wind scooper is the streamlined truncated cone component in longitudinal section, and larger diameter end is towards the right side, and smaller diameter end is towards a left side；Further improvement is that：Gusset quantity is the odd number within 3~15；On the section by front end cap body bearing hole central axis, the cooling air channel formed between gusset and front end cap body right side, flange left side is bigger closer to front end cap body bearing hole central axis, its axial dimension.Flow of cold air speed of the present invention is fast, drives hot good cooling effect.
Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of motor.
Background technology
Common motor produces certain heat in operation process, if the heat can not discharge in time will build up on into evil,
Until influence the service life of motor.Prior art has taken cooling measure, and its structure is on a motor left side, rear end cap
Provided with axially extending bore, the air vent that cold wind gas is set from the tegmental wall of rear end is inhaled into motor, and the flow direction of cold air is from the right side
To the left, until being flowed out in the air vent set from drive end bearing bracket wall, cold air takes away partial heat, plays cooling-down effect.It is but existing
The cold air for having technology to enter in motor is less, and flowing velocity is unhappy, and the thermal Finite taken away, cooling-down effect is limited, for
The larger motor of caloric value, prior art can not meet that cooling requires.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of quickening flow of cold air speed, improves and drive heat drop temp effect
Ventilated motor.
The present invention is achieved through the following technical solutions technical goal.
Ventilated motor, including drive end bearing bracket, housing, rear end cap；If the drive end bearing bracket include front end cap body, flange,
Dry gusset；Bearing hole is provided with the middle part of the front end cap body；The flange is relative with front end cap body axially spaced-apart, by uniform
In front end, some link of boards of cap body bearing hole surrounding are together；The gusset and front end cap body right side, flange are left
Several cooling air channels are formed between end face；Wind scooper is axially connected on the rear end cap inner side end；It is theed improvement is that：
The gusset is arc；The wind scooper is the streamlined truncated cone component in longitudinal section, and larger diameter end is towards the right side, minor diameter
Hold towards a left side.
In said structure, the gusset quantity is the odd number within 3~15.
In said structure, on the section by front end cap body bearing hole central axis, the gusset and drive end bearing bracket lid
The cooling air channel formed between body right side, flange left side is closer to front end cap body bearing hole central axis, its axial chi
It is very little bigger.
The present invention compared with prior art, has the positive effect that：
1st, gusset is arc in drive end bearing bracket, so, in the use of the present invention, forming spiral shape cooling wind in electric machine casing
Road, wind scooper are the streamlined truncated cone component in longitudinal section, and larger diameter end forms siphon and showed towards the right side, smaller diameter end towards a left side
As plus the spiral shape cooling air channel formed in housing, accelerating flow of cold air speed, significantly improving and drive heat drop temp effect.
2nd, gusset quantity is the odd number within 3~15, so, in the use of the present invention, forming irregular turbulent flow, enters one
Step, which improves, drives heat drop temp effect.
3rd, on the section by front end cap body bearing hole central axis, gusset and front end cap body right side, flange
For the cooling air channel formed between left side closer to front end cap body bearing hole central axis, its axial dimension is bigger, cools down wind
Road section also gradually increases, so, in the use of the present invention, also produce certain siphonage, can absorb more wind join into
Enter cooling air channel, further improve and drive heat drop temp effect.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is A-A profiles in Fig. 1.
Embodiment
The invention will be further described below according to accompanying drawing and in conjunction with the embodiments.

11）, the middle part of front end cap body 1.1 is provided with bearing hole；Flange 1.4 is relative with the axially spaced-apart of front end cap body 1.1, by being distributed on
The gusset 1.3 of the bearing hole surrounding of front end cap body 1.1 links together；Gusset 1.3 and the right side of front end cap body 1.1, flange
Cooling air channel is formed between 1.4 left sides, cooling air channel quantity is identical with the quantity of gusset 1.3；By the axle of front end cap body 1.1
On the section of bearing bore central axis, the cooling that is formed between gusset 1.3 and the right side of front end cap body 1.1, the left side of flange 1.4
Air channel is bigger closer to the bearing hole central axis of front end cap body 1.1, its axial dimension.
Wind scooper 4 is axially connected on the inner side end of rear end cap 3；Wind scooper 4 is the streamlined truncated cone structure in longitudinal section
Part, larger diameter end is towards the right side, and smaller diameter end is towards a left side.
