Abstract
The invention discloses a kind of high intensity flameproof motor rear end cap, including lid, flange, some gussets；Bearing hole is provided with the middle part of lid；Flange is relative with lid axially spaced-apart, by being distributed on some link of boards of lid bearing hole surrounding together；Several cooling air channels are formed between gusset and lid right side, flange left side；Gusset is arc；Further improvement is that：Gusset quantity is the odd number within 3~15；On the section by lid bearing hole central axis, the cooling air channel formed between gusset and lid right side, flange left side is bigger closer to lid bearing hole central axis, its axial dimension.The present invention can be sufficiently cooled to rear end cap middle (center) bearing, ensure rear end cap middle (center) bearing normal use.
Description
Technical field
The present invention relates to technical field of motors, and in particular to a kind of motor rear end plate.
Background technology
Bearing is installed, operationally rear end cap middle (center) bearing produces certain heat, shell to motor in motor rear end plate
Substantial amounts of heat is produced in body, these heats can raise rear end cap middle (center) bearing temperature, influence the normal use of bearing.Therefore,
The motor rear end plate of prior art takes certain cooling provision, but for some load are very big, caused heat is a lot
Motor, cooling capacity is still insufficient, rear end cap middle (center) bearing can not be sufficiently cooled, can not ensure rear end cap middle (center) bearing
Normal use.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes that one kind can be sufficiently cooled to rear end cap middle (center) bearing, ensured
The high intensity flameproof motor rear end cap of rear end cap middle (center) bearing normal use.
The present invention is achieved through the following technical solutions technical goal.
High intensity flameproof motor rear end cap, including lid, flange, some gussets；Bearing hole is provided with the middle part of the lid；
The flange is relative with lid axially spaced-apart, by being distributed on some link of boards of lid bearing hole surrounding together；It is described
Several cooling air channels are formed between gusset and lid right side, flange left side；It is theed improvement is that：The gusset is arc
Shape plate.
In said structure, the gusset quantity is the odd number within 3~15.
In said structure, on the section by lid bearing hole central axis, the gusset and lid right side, flange
The cooling air channel formed between left side is bigger closer to lid bearing hole central axis, its axial dimension.
The present invention compared with prior art, has the positive effect that：
1st, gusset is arc, so, in the use of the present invention, forming spiral shape cooling air channel in electric machine casing, is significantly carried
High cooling effect, rear end cap middle (center) bearing can be sufficiently cooled, ensure rear end cap middle (center) bearing normal use.
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 improves the cooling effect of the present invention.
3rd, on the section by lid bearing hole central axis, shape between gusset and lid right side, flange left side
Into cooling air channel closer to lid bearing hole central axis, its axial dimension is bigger, and cooling air channel section also gradually increases, this
Sample, in the use of the present invention, producing certain siphonage, more wind ginsengs can be absorbed and enter cooling air channel, further improved
The cooling effect of the present invention.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is A-A sectional views in Fig. 1.
Embodiment
The invention will be further described below according to accompanying drawing and in conjunction with the embodiments.
High intensity flameproof motor rear end cap shown in the drawings, including lid 1, flange 4, some gussets 3；The middle part of lid 1
Provided with bearing hole；Flange 4 is relative with the axially spaced-apart of lid 1, and one is connected to by the gusset 3 for being distributed on the bearing hole surrounding of lid 1
Rise, gusset 3 is arc, and quantity is the odd number within 3~15（In the present embodiment, the quantity of gusset 3 is 11）；Gusset 3 and lid
Formed and the quantity identical cooling air channel of gusset 3 between the right side of body 1, the left side of flange 4.
On the section by the bearing hole central axis of lid 1, between gusset 3 and the right side of lid 1, the left side of flange 4
The cooling air channel of formation is bigger closer to the bearing hole central axis of lid 1, its axial dimension.
