Description
Technical field
The present invention relates to a kind of motor technology field, and in particular to a kind of motor.
Background technology
Existing motor includes motor shaft, drive end bearing bracket, housing, rear end cap, fan, baffle plate, baffle plate is relative with rear end cap axially spaced-apart, and it is fixedly connected on rear end cap right side, fan is fixedly connected on motor shaft right-hand member, and be arranged between rear end cap, baffle plate, housing outer circumferential walls are provided with some axially arranged gussets.After fan is rotated, cold air is blowed into baffle plate end face, after being reflected through baffle plate, cold air stream takes away the heat on housing to housing, so as to reach the purpose of motor heat dissipation.The electronic function of this structure distributes certain heat, plays certain radiating effect, but radiating effect is limited, if the heat produced during motor running is more, the heat that motor is produced cannot then be distributed in time, be likely to result in the overheat of motor, damage motor.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided one kind significantly improves radiating effect, the high-temperature resistant electric machine that in time can be distributed the heat that motor is produced.
The present invention is achieved through the following technical solutions technical goal.
High-temperature resistant electric machine, including motor shaft, drive end bearing bracket, housing, rear end cap, fan, baffle plate；The baffle plate is relative with rear end cap axially spaced-apart, and is fixedly connected on rear end cap right side；The fan is fixedly connected on motor shaft right-hand member, and is arranged between rear end cap, baffle plate；The housing outer circumferential walls are provided with some axially arranged reinforcement gussets；The drive end bearing bracket includes left side flange, right flange, bearing block, some gussets；The right flange is relative with left side flange axially spaced-apart, and bearing block is arranged between left side flange, right flange；The left side flange is connected with the bearing block of centre, and right flange is integral by being arranged on the link of boards of bearing block outer wall surrounding with left side flange, bearing block outer wall；The drive end bearing bracket is fixedly attached to housing left end by right flange；The baffle plate is discoid component；It is theed improvement is that：The air channel connected with housing cavity is provided between drive end bearing bracket left side flange, right flange；The baffle plate is with diameter greater than housing section diameter；The left side flange is more than housing section diameter.
It is helical form gusset to strengthen gusset in said structure, in the housing outer circumferential walls.
The present invention compared with prior art, has the positive effect that：
1, drive end bearing bracket left side flange, the air channel connected with housing cavity is provided between right flange, baffle plate is with diameter greater than housing section diameter, left side flange is more than housing section diameter, so, the present invention is when in use, fan is rotated and for cold air to blow to baffle plate end face, after being reflected through baffle plate, cold air is oriented to through strengthening gusset in housing outer circumferential walls, flow through housing exterior walls, flow to drive end bearing bracket left side flange right side, after being reflected through drive end bearing bracket left side flange right side, cold air from drive end bearing bracket left side flange, air channel between right flange is flowed into housing cavity, motor cavity is cooled down, significantly improve radiating effect, the heat that motor is produced can be distributed in time.
2nd, it is helical form gusset to strengthen gusset in housing outer circumferential walls, increases cooling path length, further improves radiating effect.
