Background technology
Motor is a kind of rotary electric device, converts electrical energy into mechanical energy.Motor mainly includes one in order to produce
The stator winding of the electric magnet winding in magnetic field or distribution and a rotating armature or rotor.Work in stator winding rotating excitation field
With under, play the role of in its armature squirrel-cage aluminum frame electric current by and be subject to magnetic field so that it is rotated.
Cage-type rotor asynchronous motor (y serial motors) due to have efficiently, energy-conservation, noise are low, vibration is little, lightweight,
The advantages of dependable performance, it is widely used in compressor.The structure of y serial motors mainly includes motor cabinet, is arranged on motor
Stator in seat and rotor, the rear and front end of motor cabinet is respectively mounted drive end bearing bracket and rear end cap, setting and rotor outside rear end cap
The fan being fixedly connected, the outside setting fan housing of fan, fan housing is turned back with arcuate motion forward end, the cooling wind that fan is blown out
Guide motor front end into, if setting direct-axis is used for cooling down the radiating ribs of rotor to the arterial highway of distribution on motor cabinet.
In running, the various losses of generation are changed into heat to y serial motors, so that each part of motor is generated heat, temperature
Raise, its temperature raises the service life directly affecting motor and operational reliability it is therefore necessary to ensure relatively low temperature rise ability
Preferably normal work.The bearing of especially motor front end, does not cool down wind action, and by rotor end ring and the cooling wind wing
Structure design and limited space restriction, the heat between the end ring of rotor and bearing cannot be to external diffusion, and at present
Common motor does not also reduce the structure of temperature rise to this design, when motor operating temperature rise is too high, can only carry out motor and tear machine open
Overhaul, and carry out the project setting of complexity, just can reach the effect reducing temperature rise.
Utility model content
This utility model technical issues that need to address are to provide a kind of tool that especially can reduce motor front end bearing temperature rise
There is the motor of heat-insulated spoiler.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of motor with heat-insulated spoiler, including motor cabinet, stator, end ring position arrange the cooling rotor of the wind wing,
Drive end bearing bracket and rear end cap,
Also include being arranged on the heat-insulated spoiler inside drive end bearing bracket；Described heat-insulated spoiler includes linkage section and diversion section,
Linkage section is the ring slab structure being arranged in the flat plane of the pre- ream in drive end bearing bracket inside edge；Diversion section smooth connection is in linkage section
Inner ring surface on, be from drive end bearing bracket oblique subsequently point to rotor side, bore tapers into, rotor side be provided with middle mistake
The ring diversion plate structure in hole.
The above-mentioned motor with heat-insulated spoiler, the radius of the via of described diversion section respective rotor side be less than the wind wing with
The distance between rotor center axle.
The above-mentioned motor with heat-insulated spoiler, described heat-insulated spoiler is glass epoxy.
The above-mentioned motor with heat-insulated spoiler, described heat-insulated spoiler is fixed by screws in inside drive end bearing bracket, heat-insulated
Between spoiler and drive end bearing bracket, plain washer is installed, locking spring washer is installed between heat-insulated spoiler and screw.
This utility model, after using technique scheme, has an effect of following technological progress:
This utility model installs heat-insulated spoiler inside drive end bearing bracket, blows to the heat of bearing chamber using heat-barrier material isolation
Wind；The planform of heat-insulated spoiler serves choked flow effect, can preferably guide wind to try one's best and few blow to bearing portion, fall
The temperature rise of low bearing region；The height of via is more low with than the wind wing, the wind that the wind wing gets can be made to try one's best and few flow to axle
Hold, reduce cavity and lead so that distinguished and admirable speed increases further, be conducive to front end hot blast to accelerate to distribute.This utility model solves
Motor, in the case of not changing external structure, reduces bearing temperature, extends the effect of electrical machinery life.This utility model will with bolt
Heat-insulated spoiler is arranged on inside drive end bearing bracket, anti-skidding with spring washer during installation, assembles and convenient disassembly, reliable.
Brief description
Fig. 1 is structural representation of the present utility model.
The each label of in figure is expressed as: 1, motor cabinet, 2, stator, 3, the wind wing, 4, drive end bearing bracket, 5, connection end, 6, diversion section, 7,
Bearing, in figure is the flow direction of wind with arrow solid line.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further details to this utility model:
This utility model is as shown in figure 1, include motor cabinet 1, the stator 2 being arranged in motor cabinet 1 and rotor, the end of rotor
