Description
Technical field
Motor device technical field is the utility model is related to, especially a kind of cold bearing assembling structure of motor oil.
Background technology
It is also different to the structural requirement of motor because the application scenario of motor is different, lubrication to motor bearings and
It is one of them to cool down requirement.
At present, for middle size motor generally using the bearing seal structure of grease lubrication and cooling, in this airframe bearing
The encapsulating method used between lid and axle is oil groove sealing.It can not meet for the bearing assembling structure of oil groove sealing means
Oil lubrication and the use of cooling occasion.
Utility model content
A kind of the shortcomings that the applicant is directed in above-mentioned existing production technology, there is provided cold bearing of motor oil rational in infrastructure
Assembling structure, so as to improve sealing effectiveness, the sealing of internal bearing cover is ensure that, fluid will not be entered in motor, protect motor
Service life.
Technical scheme is as follows used by the utility model：
A kind of cold bearing assembling structure of motor oil, including rotating shaft, the outer ring of the rotating shaft are provided with bearing by bearing
Seat, the outer ring of the rotating shaft are also equipped with axle sleeve, and the outer ring of the axle sleeve is provided with internal bearing cover by oil sealing, in the bearing
The end face of lid is connected by the end face seal of O-ring and bearing block；The internal bearing cover is also locked by fastener and bearing block.
Further improvement as above-mentioned technical proposal：
Stepped hole is provided with the middle part of the internal bearing cover, installation oil sealing is coordinated at the stepped hole, the internal bearing cover
Uniform intervals are provided with four connection screw thread holes on inner peripheral surface, and the screwed hole is blind hole, is additionally provided with its inner peripheral surface
The groove of mounting O-shaped rings, multiple oil grooves are provided with the outer circumference surface of the internal bearing cover.
The beneficial effects of the utility model are as follows：
The utility model is compact-sized, reasonable, easy to operate, by using oil injection type close on the internal bearing cover of motor
Envelope, ensure that the sealing effectiveness of bearing, the defects of avoiding in the prior art using oil groove sealing, go for oil cooling bearing
Assembling, substantially increases use reliability.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.
As shown in Figure 1, Figure 2 and Figure 3, the cold bearing assembling structure of the motor oil of the present embodiment, including rotating shaft 1, rotating shaft 1
Outer ring is provided with bearing block 6 by bearing 5, and the outer ring of rotating shaft 1 is also equipped with axle sleeve 2, and the outer ring of axle sleeve 2 is installed by oil sealing 3
There is internal bearing cover 4, the end face of internal bearing cover 4 is connected by O-ring 7 with the end face seal of bearing block 6；Internal bearing cover 4 also passes through
Fastener is locked with bearing block 6.
The middle part of internal bearing cover 4 is provided with stepped hole 403, and installation oil sealing 3, the inner circle of internal bearing cover 4 are coordinated at stepped hole 403
Uniform intervals are provided with four connection screw thread holes 402 on side face, and screwed hole 402 is blind hole, and peace is additionally provided with its inner peripheral surface
The groove 401 of O-ring 7 is filled, multiple oil grooves 404 are provided with the outer circumference surface of internal bearing cover 4.
In actual use, axle sleeve 2 is enclosed in rotating shaft 1, oil sealing 3 is pressed into the rear enclosure of internal bearing cover 4 in rotating shaft 1, axle
5 are held in rotating shaft 1, O-ring 7 is put into the groove of internal bearing cover 4 and fixed with glue, and bearing block 6 is enclosed on bearing, finally by axle
Hold the medial surface that inner cap 4 is fixed by bolts to bearing block 6；Ensure sealing effectiveness, bearing oil is may not flow into the interior of motor
Portion.Internal bearing cover 4 is processed into blind hole with loading O-ring 7 and the connecting screw hole of internal bearing cover 4 in the mating surface of bearing block 6, so enters
One step ensures the sealing effectiveness of bearing.
Above description is to explanation of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope within the scope of protection of the utility model, can make any type of modification referring to claim.
