Abstract
The utility model discloses a fixing structure of a rotating shaft of a motor. The fixing structure of the rotating shaft of the motor comprises a bearing seat which is fixedly arranged on the motor, the bearing seat is provided with a circular groove, a bearing is arranged inside the circular groove in an internal embedding mode, and the bearing is arranged on the rotating shaft of the motor in sleeved mode. An elastic fixing ring is arranged between the bearing and the circulating groove, and the elastic fixing ring is provided with a plurality of elastic sheets which contact with the inner wall of the circulating groove. When the motor works, vibration generated by the rotating shaft can be weakened or counteracted through elastic force generated by the elastic sheets and the inner wall of the groove, in addition, the elastic fixing ring can effectively compensate an oversize gap between the bearing and the bearing seat caused by machining errors of the bearing seat and abrasion in the process of using. Therefore, damages to the motor by vibration of the rotating shaft of the motor are reduced, and normal using of the motor is guaranteed.
Description
Technical field
The utility model relates to the fixed structure of a kind of fixed structure, particularly a kind of machine shaft.
Background technology
As everyone knows, exist the gap between bearing on the motor and the bearing pedestal, when machine operation, machine shaft can shake, even also can be so that bearing and bearing pedestal collision friction, cause the gap between bearing and the bearing pedestal constantly to increase, thereby so that the vibrations of machine shaft are more and more violent, had a strong impact on the normal use of motor.
The utility model content
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and can realize backlash compensation, reduces the fixed structure that machine shaft shakes when machine operation.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of fixed structure of machine shaft, comprise the bearing pedestal that is fixedly mounted on the motor, be provided with circular groove on the bearing pedestal, interlocking is equipped with bearing in the circular groove, the bearing socket is installed on the machine shaft, be provided with the flexible fastening circle between described bearing and the circular groove, be provided with a plurality of shell fragments that touch with the circular groove inwall on the flexible fastening circle, during machine operation, the vibrations that rotating shaft produces can weaken by the elastic force that shell fragment and groove inwall produce or offset, thereby reduce the rotating shaft vibrations to the infringement of motor, guaranteed the normal use of motor.
Further, described flexible fastening circle comprises cup dolly, and the circumferential edges place of cup dolly is evenly distributed with a plurality of shell fragments, and above-mentioned a plurality of shell fragments that are evenly distributed on the cup dolly can weaken the vibrations on the rotating shaft one way or another or offset.
The beneficial effects of the utility model are: because the utility model is provided with a flexible fastening circle between bearing and circular groove, the vibrations that rotating shaft produces during with machine operation by the flexible fastening circle weaken or offset, thereby avoided bearing pedestal to produce vibrations because mismachining tolerance causes the excesssive gap between bearing and the bearing pedestal, guaranteed the normal use of motor; In addition, the cup dolly edge of flexible fastening circle is evenly distributed with a plurality of and the contacted shell fragment of circular groove inwall, can produce certain its axle center effect, can eliminate machine shaft partly process with assembling process in the two ends decentraction phenomenon that produces, reduce the frictional heating of bearing, because the flexible fastening circle has certain backlash compensation effect can reduce the requirement on machining accuracy of bearing pedestal, can remove finishing step to the less demanding motor of part, reduces production costs.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is explosive view of the present utility model;
Fig. 2 is the installation diagram of the utility model Elastic retainer plate and bearing pedestal;
Fig. 3 is the part drawing of the utility model Elastic retainer plate.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of fixed structure of machine shaft, comprise the bearing pedestal 1 that is fixedly mounted on the motor, be provided with circular groove 10 on the bearing pedestal 1, circular groove 10 interior interlockings are equipped with bearing 2, bearing 2 sockets are installed on the machine shaft 3, be provided with flexible fastening circle 4 between described bearing 2 and the circular groove 10, be provided with a plurality of shell fragments 41 that touch with circular groove 10 inwalls on the flexible fastening circle 4, above-mentioned flexible fastening circle 4 preferentially selects the Thin Elastic stainless steel to make, guaranteeing that flexible fastening circle 4 has enough flexible whiles, can also reduce production costs, it is also passable that certain flexible fastening circle 4 selects other materials to make.
Further, described flexible fastening circle 4 comprises cup dolly 40, the circumferential edges place of cup dolly 40 is evenly distributed with a plurality of shell fragments 41, shell fragment quantity and the size of above-mentioned flexible fastening circle 4 can freely be selected as required, when flexible fastening circle 4 is installed between circular groove 10 and the bearing 2, the cup dolly 40 of flexible fastening circle 4 is near circular groove 10 bottoms, shell fragment 41 is subject to the extruding of circular groove 10 inwalls and contacts with circular groove 10 inwalls, and the diameter of described cup dolly 40 is slightly less than the diameter of circular groove 10.
When flexible fastening circle 4 is fixedly mounted between bearing 2 and the circular groove 10, during machine operation, the vibrations that machine shaft 3 produces can pass to flexible fastening circle 4 by bearing 2, so that pushing mutually with circular groove 10 inwalls, the shell fragment 41 of flexible fastening circle 4 produces reverse elastic force, thereby weaken or offset the vibrations of machine shaft 3, the sound that sends because of vibrations when reducing machine shaft 3 work, and so that the work of motor is more steady, prevent that effectively machine shaft 3 from causing the lost of life of motor because of the friction that collides of vibrations and motor housing.
The above only is preferential execution mode of the present utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection range of the present utility model.
