Abstract
The utility model relates to a shaft structure of a motor for an industrial sewing machine. The shaft structure comprises a motor stator, a motor shaft, a motor front end cover and a motor rear end cover, wherein, the end of the motor rear end cover corresponding to the motor shaft is provided with bearings, the front end face of the motor shaft is connected with an elastic cushion through a connection part, the elastic cushion is connected with a connection block together through a connection part, and the connection block is fixed with a rotary shaft of a driven machine together through a fastening part. The shaft structure can effectively shorten the connection length between a motor main body and the rotary shaft of the driven machine and between the motor and the rotary shaft of the driven machine, assembly of the motor and the industrial sewing machine is facilitated, and due to the fact that a bearing seat on the motor front end cover is canceled, the structure of the motor front end cover is simplified, and then manufacture cost of the motor is reduced.
Description
Technical field
The utility model relates to a kind of structure of motor shaft, relates in particular to a kind of axle construction of Machine Using For Industry Sewer.
Background technology
In the prior art, motor shaft with normally adopted shaft coupling to come transferring power by being connected of drive machines rotating shaft.That is, shaft coupling one end connects the main shaft of motor, and its other end connects by the rotating shaft of drive machines, and is connected through bearing between the two ends of motor shaft and the motor stator.Because shaft coupling needs certain length; Thereby cause motor and increased in the axial length that is connected by drive machines; And need be respectively equipped with and the corresponding bearing pedestal of bearing at the two ends of motor stator; And then making motor body bigger in axial size, this is for very under the condition of limited, directly affecting the assembling of industrial sewing machine and the volume and the performance of vehicle at the parts configuration space of industrial sewing machine.
Summary of the invention
The purpose of the utility model provides a kind of axle construction of Machine Using For Industry Sewer, can effectively shorten axial length and the motor of motor with by the axial length that is connected between the drive machines.
The utility model includes motor stator; Motor shaft; Motor front end housing and back end cover for motor, the corresponding position of described back end cover for motor and motor shaft is equipped with bearing, and the front end of said motor shaft is connected with cushion through connector; Said cushion links together through connector and link block, said link block through securing member be fixed together by the rotating shaft of drive machines.
Said cushion is the cylinder that elastomeric material is processed, and its cross section is provided with 2-4 through hole, and described connector is a bearing pin, and said cushion is connected with the front end face of motor shaft through this bearing pin.
The middle part of said link block is provided with through hole, but an end face of said link block is provided with the groove of the said cushion of holding portion, but is provided with the groove of the said cushion of holding portion at the front end face of said motor shaft.On the cross section of cushion, be provided with 2-4 through hole, described connector is a bearing pin, and said cushion is connected with link block through this bearing pin.
The through hole of said link block is set in by the end of drive machines rotating shaft; Saidly be processed with platform on the excircle of drive machines rotating shaft; Securing member is a screw, this screw through said link block screw radially be meshed by the platform on the drive machines rotating shaft.Be fixed together through fastening bolt and motor front end housing by the housing of drive machines.
Because an end of the motor shaft of the utility model has then been cancelled the front axle elongated end, adopted the link block structure that comprises the shaft coupling function, through rubber blanket and link block be connected by the rotating shaft of drive machines; Therefore; One end of motor shaft (rotor) can be rotatablely moved by bearings, and its other end then forms soft connection through link block, rubber blanket; Cancelled the bearing pedestal of motor front end housing; Thereby can guarantee that motor only is unlikely to an end and supports and cause the motor shaft unbalance stress and be stuck when transferring power, can reach again simultaneously motor shaft with by the requirement of the axiality of drive machines rotating shaft and even running, and effectively shorten the length of motor main body.In addition; Because the shaft coupling function is solidificated on the motor shaft; This structure can shorten motor shaft with by the length that is connected of drive machines rotating shaft, this not only helps the assembling of motor and industrial sewing machine, and also owing to cancelled the bearing pedestal of motor front end housing; Simplify the structure of motor front end housing, further reduced the manufacturing cost of motor.
