Abstract
The utility model discloses an improved generation motor bearing structure, including being used for connecting the bearing of the connector of motor and the flange that is used for fixing bearing, the flange is provided with the protruding portion, the protruding portion is crowded to butt the bearing and fixes the bearing in the protruding portion, be provided with at least one rubber buffer rod on the opposite face of flange and connector, be provided with the spring in the rubber buffer rod, rubber buffer rod's length is less than the length of flange apart from the bearing. Compared with the prior art, the utility model, rubber buffer rod can give the connector outside thrust to can cushion the most axial force of motor connector, make the connector can not take place the position easily and remove, promote the stability of connector in the bearing by a wide margin, the connector reduces to the friction loss of bearing by a wide margin, thereby has promoted the result of use of bearing, has prolonged the life of bearing.
Description
Technical field
This utility model is related to a kind of bearing arrangement and in particular to a kind of improved electric motor bearing arrangement.
Background technology
Existing motor bearings structure mainly connects the union joint of motor by bearing, is then consolidated using flange
Fixed, but the bonding strength between this connected mode motor connector and bearing is not very big although dealing with routine enough
Use requirement, but when motor bears axial impact force, such as in oilfield drilling, drilling well meet special formation or
Rock, motor can constantly be subject to axial impact, and this impulsive force easily leads to motor connector to occur axially in original mechanism
Play, so that motor connector relative position within the bearing changes, bears this axial impact for a long time, can be right
Bearing inner surface produces friction and accelerates the damage of bearing, the using effect of impact bearing, the service life of shortening bearing.
Content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, provide a kind of bonding strength big, for motor connection
The improved electric motor bearing arrangement of head good fixing effect.
Technical scheme：For achieving the above object, this utility model provide a kind of improved electric motor bearing arrangement, including for
Connect the bearing of union joint and the flange for fixing bearing of motor, described flange is provided with protuberance, and described protuberance squeezes
Against bearing, bearing is fixed in protuberance, described flange and the opposite face of union joint are provided with least one rubber buffer
Rod, is provided with spring in described rubber buffer rod, the length of described rubber buffer rod is less than the length apart from bearing for the flange.
Design principle of the present utility model is：Setting rubber buffer rod on the opposite face with union joint for the flange, rubber delays
It is provided with spring, union joint configures in bearing, and rubber buffer rod can abut against union joint in punching rod, and rubber buffer rod
Give union joint outside thrust to after-contraction under the action of the spring, so that rubber buffer rod can offset gentle washing out
Significant component of axial impact force is so that union joint will not occur position to move, thus significantly reducing in bearing easily
Union joint is for the frictional dissipation of bearing.
Further, described protuberance and the opposite face of motor are provided with least two horizontal open tubular columns, stirrup
It is housed in open tubular column and can move back and forth in open tubular column, the opening of described open tubular column is provided with bayonet lock, described bayonet lock
Run through open tubular column and stirrup is used for fixing stirrup, using shift in position in open tubular column for the stirrup so that stirrup energy
Enough opposite faces smoothly abutting against motor and protuberance, thus increased the resistance that motor moves axially to bearing direction, plus
The big degree of difficulty of motor movement, improves the stability of motor position.
Further, the quantity of described rubber buffer rod is two and is each perpendicular to flange setting, maximized embodies
Rubber buffer rod is for the thrust of union joint.
Further, the distance between described protuberance and motor are less than the length sum of open tubular column and stirrup, thus
May insure that stirrup can abut against motor.
Further, the quantity of described open tubular column be two and respectively be located at protuberance top and bottom.
Beneficial effect：Compared with prior art, rubber buffer rod can give union joint outside thrust to this utility model,
Such that it is able to buffer the most axial force of motor connector so that union joint will not occur position to move easily, significantly carry
Rise stability in bearing for the union joint, union joint is greatly reduced for the frictional dissipation of bearing, thus improving bearing
Using effect, extends the service life of bearing.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model it should be understood that these embodiments are only used for
