Abstract
The invention belongs to the technical field of sewing machines, and relates to a special motor rotor for a sewing machine. The special motor rotor comprises a motor rotor and a sewing machine spindle, wherein a motor rotor mounting part is arranged at one end of the sewing machine spindle; and the motor rotor is mounted on the motor rotor mounting part. Compared with the prior art, the special motor rotor for the sewing machine in the invention has the beneficial technical effects that: the integrated sewing machine spindle is used to replace the original motor shaft, coupling and sewing machine shaft; the production cost is low and the positioning is accurate; transmission brings little vibration and low noise so as to save energy; and the special motor rotor is applicable to various types of sewing machines such as a flat seaming machine, an overlock machine and the like.
Description
Technical field
The invention belongs to the technical field of the motor that uses on the Sewing machines, refer in particular to a kind of Sewing machines motor special rotor.
Background technology
At present, drive motors on the various Sewing machiness all is independently to be installed on the sewing machine head, and the main shaft on the sewing machine head is connected by shaft coupling with motor shaft, its weak point is: the installation site of motor shaft and machine spindle is difficult for accomplishing the concentric installation, make that the dismounting difficulty is big, the location is inaccurate, cause transfer motion power to be obstructed, consume power of motor, increase wearing and tearing and noise.
Summary of the invention
The purpose of this invention is to provide a kind of accurate positioning, energy-conservation and Sewing machines motor special rotor that noise is little on Sewing machines, installed.
The object of the present invention is achieved like this:
A kind of Sewing machines motor special rotor includes rotor and machine spindle, and an end of described machine spindle is provided with the rotor installation portion, on the rotor installation portion rotor is installed.
Above-mentioned machine spindle is yi word pattern d-axis or bent axle.
The outer surface of the machine spindle of above-mentioned machine spindle and rotor junction is provided with the annular knurl structure.
Above-mentioned annular knurl structure is a straight knurling.
Above-mentioned rotor and the connected mode of machine spindle are that key is connected or are threaded or annular spring connects or interference fit connects or its combination.
The present invention gives prominence to compared to existing technology and beneficial technical effects is:
1, the machine spindle of integral type manufacturing of the present invention replaces original motor shaft, shaft coupling and former machine spindle, has saved the shaft coupling between motor shaft and the machine spindle, has reduced production cost.
2, the present invention replaces original motor shaft and machine spindle with a machine spindle, and the axis of two axles is located inaccurate problem when having avoided original motor shaft and machine spindle to install, and vibration is light during transmission, noise is little, and then energy-conservation.
3, of the present invention being applicable on various types of Sewing machiness such as flat seam machine, overlock machine used.
Description of drawings
Fig. 1 is a schematic perspective view of the present invention.
Fig. 2 is the three-dimensional exploded view of rotor of the present invention and machine spindle.
Fig. 3 is the schematic perspective view of the machine spindle of band straight knurling of the present invention.
The specific embodiment
The present invention is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-3:

Above-mentioned machine spindle 1 is yi word pattern d-axis or bent axle, so that be installed in cooperating on various types of Sewing machiness.
Above-mentioned machine spindle 1 is provided with the annular knurl structure with the outer surface of the machine spindle 1 of rotor 2 junctions.
Above-mentioned annular knurl structure is a straight knurling, can certainly be other annular knurl structure example such as rib type line annular knurl etc.
Above-mentioned rotor 2 and the connected mode of machine spindle 1 are that key is connected or are threaded or annular spring connects or interference fit connects or its combination.
Above-mentioned rotor with the connected mode of machine spindle is: be connected to by long key between rotor 2 and the machine spindle 1 on the keyway 21,12 corresponding on rotor 2 and the machine spindle 1, and be connected to two annular springs in two annular slots 11 of machine spindle 1 rotor 2 is connected on the rotor installation position 13 of machine spindle 1; Or being provided with the annular knurl structure at the outer surface of machine spindle 1 and the machine spindle 1 of rotor 2 junctions, machine spindle 1 and rotor 2 are by colding pressing or the form realization interference fit of hot jacket is connected; Can certainly rotor 2 be fixed on the rotor installation portion 13 or 13a of machine spindle 1 screw.
Above-mentioned Sewing machines motor special rotor is directly installed on various types of head of sewing machine such as flat seam machine or overlock machine, and use bearings, cooperate with the supporting motor stator of installing and to drive machine spindle and rotate, because the present invention has replaced motor shaft, machine spindle and shaft coupling thereof on the original Sewing machines with a machine spindle, make simple in structure, easy for installation, the accurate positioning during installation, save the set-up time, the reliable operation of Sewing machines.
The foregoing description is preferred embodiment of the present invention only, is not to limit protection scope of the present invention according to this, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
