Abstract

The utility model discloses an electromotor with a sliding rotating shaft, which comprises a motor shell, a motor shell front cover, a machine shell rear cover, a stator winding, a rotor winding, a rotor rotating shaft, a fan, a fan housing, a bearing, an oil seal, a starting winding and other components. The rotor rotating shaft for connecting the rotor winding in the electromotor is a hollow pipe column; a convex pin distributed in a cross shape is arranged on the inner wall at one end of a pipe cavity; a sliding shaft is penetrated in the pipe cavity of the rotor rotating shaft; a pin slot distributed in a cross shape is arranged on the shaft wall at one side of the sliding shaft; the pin slot is meshed with the convex pin; one end of the sliding shaft is connected with a tail cone component for connecting an air cylinder, and the other end thereof is the load side of the electromotor; and the sliding shaft not only can rotate along with the rotor rotating shaft, but also can carry out displacement sliding along the axial direction under the effect of outside force. The electromotor is favor of solving the stepping technical problem that certain parts are required to be rotated and moved simultaneously on the axial direction in the machinery, and also fills in the gap that the load shaft of the electromotor directly carries out the space displacement action.

Description

A kind of motor that sliding axle is arranged

Technical field:

The utility model relates to electric motors, relates in particular to the load axis of motor.

Technical background:

Motor is as a kind of power set, all have a wide range of applications in every field, existing motor can be divided into single-phase, threephase motor or synchronous or asynchronous motor, no matter be which kind of type, its load axis that is wound with the rotor winding all has only the effect of rotation, as everybody knows, in machinery production is made, many times not only need motor to rotate certain parts, also need these parts are done corresponding displacement along the axial direction of motor, so that reach certain purpose, for example, emery wheel with regard to ceramic circular arc machine, not only need during its work it to be rotated with motor, also need to promote with stroke cylinder, so that reach the purpose of stepping, the gap that the compensation emery wheel produces because of wearing and tearing, because the load axis of existing motor can not slide vertically, so existing ceramic circular arc machine nearly all adopts a kind of edging wheel transmission device that is referred to as " artillery " in the industry, traditional edging wheel transmission device exists unloaded overweight, power consumption is big, the problem of life of product shortening and maintenance cost, I once improved at these problems in Chinese patent application number 200720059492.7 described " a kind of transmission devices of edging wheel ", although this scheme can have been improved the problems referred to above, its cost of manufacture aspect does not change more significantly.

The utility model content:

In order to reduce the manufacturing cost of existing ceramic circular arc machine, the purpose of this utility model provides a kind of motor that sliding axle is arranged, replace the very big edging wheel transmission device of consumption in the ceramic circular arc machine with it, compared with prior art, the load axis of this motor not only can rotate, and can also in axial direction do displacement and slide.

The utility model will be achieved through the following technical solutions:

A kind of motor that sliding axle is arranged, all parts that contain existing motor assembly, promptly comprise casing, front cover, rear chassis, stator winding, the rotor winding, rotor shaft, fan, fan guard, bearing, oil sealing, start members such as winding, described stator winding is fixed in the inner chamber of casing, the rotor shaft that connects the rotor winding is hollow tubing string, it and be fixed on casing before, bearing in the bonnet connects, the inwall of tube chamber one end is provided with and is the protruding pin that crosswise distributes, other end inwall is provided with as dried groove, and the rotor winding is encircled in stator winding; Be coated with a sliding axle in the official jargon of described rotor shaft, the axial wall of this sliding axle one side is provided with the cotter way that crosswise distributes, cotter way and described protruding pin are bitten and are closed, two termination is provided with connecting thread, one termination of described sliding axle is useful on the tail cone assembly that connects cylinder, and the other end is the load side of described motor; Be lined with o type rubber ring between sliding axle and described groove; Described sliding axle not only can be followed the rotor shaft rotation, can also do displacement vertically and slide under the effect of external force.

Described tail cone assembly is made up of conical shell, cap, bearing, cylinder gland and attachment screw, during installation, earlier with bearing fixing in the inner chamber that conical shell and cap constitute, again with bearing holder (housing, cover) on the unload side of described sliding axle, compress cap at the sliding axle end nut of screwing on, and then will connect the cylinder gland that cylinder uses and be connected on conical shell and the cap with screw.

The beneficial effect of motor described in the utility model is: because this motor connects the rotor shaft of rotor winding is empty tube column, the inwall of official jargon one end is provided with and is the protruding pin that crosswise distributes, there is axial wall to be provided with the sliding axle that is crosswise distribution cotter way equally, and protruding pin and cotter way interlock mutually, one end of sliding axle is connected with the tail cone assembly that is used to connect cylinder, so the sliding axle as load axis on this motor not only can rotate, can also do displacement in the axial direction slides, this shows, this technical scheme not only helps solving to need in the machinery to rotate and the stepping technique problem of certain parts of simultaneous displacement in the axial direction, also fill up the induction-motor load axle and participated in the blank that space displacement moves, the application function of the motor that gained directly.
