Abstract
The utility model discloses a non-playing/non-jittering motor. The non-playing/non-jittering motor comprises a motor housing and a motor rotating shaft. The non-playing/non-jittering motor is characterized in that a front end and a rear end of the motor housing are respectively provided with a front end cover and a rear end cover, rolling bearings are respectively provided on the front end cover and the rear end cover, and the motor rotating shaft is connected between the rolling bearings in a sleeving manner; and a tail portion of the motor rotating shaft is provided with a nut, and the nut is pressed tightly on an inner ring end face of the rolling bearing of the rear end cover. According to the utility model, the nut is used to adjust the axial displacement spacing of the motor shaft, and the axial displacement playing caused by the dimension error in the production and assembling of the motor shaft is compensated; the multipoint positioning of the front and the rear bearings eliminates the radial jittering of the motor shaft; and the non-playing/non-jittering motor has a simple structure, is convenient to install and adjust, and can adjust the axial displacement of the motor shaft according to using needs.
Description
Technical field
The utility model relates to motor, and is especially a kind of without play, the motor of beating.
Background technology
The axial endplay of motor just refers to, machine shaft is at work along the inevitable minute movement of axis direction.Axis direction is exactly the direction of axle, is exactly the direction on the face of cylinder of axle perpendicular to axis direction.The motor shaft play makes vibrations, the noise of motor become large so that binding site gap that originally should not relative motion becomes large, in addition " sweeping thorax " appears may; Beating of motor refer to, by machine shaft in same cross section on the real surface each point to the maximum variation of reference axis wire spacing.It briefly is exactly the size of machine shaft machine shaft surface jerk value in a plurality of cross sections when rotating with the centre of gyration.Above two kinds of machine shaft offset phenomenas all cause useful life of motor and operating accuracy and seriously influence.
The utility model content
The purpose of this utility model provide that a kind of capable of regulating machine shaft axial displacement, multipoint positioning eliminate that machine shaft beats without play, the motor of beating.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of without play, the motor of beating, comprise: electric machine casing, machine shaft, it is characterized in that: be respectively equipped with front end housing and rear end cap in the rear and front end of electric machine casing, be equipped with rolling bearing at front end housing and rear end cap, machine shaft is socketed between the rolling bearing; Afterbody at machine shaft is provided with nut, and this nut is pressed on the rolling bearing inner ring end face of rear end cap.
Preferably, described machine shaft afterbody shaft shoulder end face is lower than the rolling bearing inner ring end face.
Preferably, between the shaft shoulder of described machine shaft and rolling bearing, also be provided with stop washer.
Preferably, rolling bearing is self-aligning ball bearing on the described rear end cap.
Preferably, described front end housing and rear end cap are fixedly connected with electric machine casing by screw respectively.
Preferably, rolling bearing quantity is two on the described rear end cap.
Preferably, described nut is round nut.
After the utility model adopts said structure, owing to having adopted nut to adjust the axial displacement spacing of motor shaft, compensated the axial displacement play that the scale error of motor shaft in producing and assembling causes; The multipoint positioning of front and back bearings has been eliminated the motor shaft run-out; The utility model is simple in structure, install easy to adjust, can be according to using needs adjust the axial displacement of machine shaft.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged view of Fig. 1.
Among the figure: 1, electric machine casing, 2, machine shaft, 21, the shaft shoulder, 3, front end housing, 4, rear end cap, 5, rolling bearing, 6, nut, 7, stop washer.
Embodiment
As shown in Figure 1 and Figure 2, a kind of without play, the motor of beating, comprise: electric machine casing 1, machine shaft 2, it is characterized in that: be respectively equipped with front end housing 3 and rear end cap 4 in the rear and front end of electric machine casing 1, be equipped with rolling bearing 5 at front end housing 3 and rear end cap 4, machine shaft 2 is socketed between the rolling bearing 5; Afterbody at machine shaft 2 is provided with nut 6, and this nut 6 is pressed on the rolling bearing 5 inner ring end faces of rear end cap 4.
Preferably, the described machine shaft 2 afterbody shaft shoulders 21 end faces are lower than rolling bearing 5 inner ring end faces.
Preferably, between the shaft shoulder 21 of described machine shaft 2 and rolling bearing 5, also be provided with stop washer 7.
Preferably, rolling bearing 5 is self-aligning ball bearing on the described rear end cap 4.
Preferably, described front end housing 3 and rear end cap 4 are fixedly connected with electric machine casing 1 by screw respectively.
Preferably, rolling bearing 5 quantity are two on the described rear end cap 4.
Preferably, described nut 6 is round nut.
Operation principle: machine shaft 2 guarantees the stationarity of the radial rotating of machine shaft 2 by rolling bearing 5 location on front end housing 3 and the rear end cap 4; The nut 6 of machine shaft 2 is adjusted tension machine shaft 2, is that the shaft shoulder 21 of machine shaft 2 is close to rolling bearing 5, eliminates the axial movement value of machine shaft 2.
After the electric machine assembly assembling is correct, tighten the nut 6 of machine shaft 2 afterbodys, under the interaction force between nut 6 and the rolling bearing 5, the reaction force of nut 6 is extracted machine shaft 2 out, machine shaft 2 shaft shoulders 21 are close to rolling bearing 5, thereby have eliminated the axial endplay of machine shaft 2.
The above is preferred implementation of the present utility model; certainly can not limit with this interest field of the utility model; should be understood that; for those skilled in the art; the technical solution of the utility model is made amendment or is equal to replacement, do not break away from the protection range of technical solutions of the utility model.
