The invention discloses a clutch motor of a sewing machine, comprising a housing, a seal cover and a control rod installed on the seal cover, wherein a clutch is installed in the housing and the seal cover and respectively connected with a rotor and an output shaft, and a abrasion-resistant ring is installed on the inner wall of a cylinder of the seal cover in contact with the output shaft and is tightly matched with the cylinder. When the control rod controls the movement of the output shaft, the abrasion of the inner wall of the cylinder can be prevented so that the normal work of the motor is ensured and the service life of the motor is prolonged.
Description
Technical field
The present invention relates to a kind of drive motors, particularly Sewing machines clutch motor.
Background technology
Existing sewing machine clutch motor comprises shell, capping and is installed in control lever in the capping that in shell and the capping clutch is installed, clutch is connected with output shaft with rotor respectively.Motor can produce a large amount of heats in the course of the work, and because how the material of existing shell and capping is cylinder iron made, the heat that motor produced can not loose in time, influences the service behaviour of motor, and the people is scalded in serious meeting.And, cylinder iron shell of Zhi Zaoing and capping production technology more complicated, energy consumption height, contaminated environment.So, people have adopted the reasonable aluminium alloy of radiating effect to make shell and capping, yet the control lever of described Sewing machines clutch motor will often be controlled output shaft and move, the part that output shaft bearing contacts with capping and the through hole of control lever are easy to and will wear and tear, thereby influence the serviceability of motor, even cause motor not use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide relatively long Sewing machines clutch motor of a kind of stable performance, service life.
The technical solution adopted for the present invention to solve the technical problems is: Sewing machines clutch motor, comprise shell, capping and be installed in control lever in the capping, in shell and the capping clutch is installed, clutch is connected with output shaft with rotor respectively, it is characterized in that: the capping cylinder inner wall that contacts with output shaft is equipped with wear ring, and wear ring and cylinder closely cooperate.
Wherein, described control lever is connected with capping by pin, and the through hole that pin passes all is provided with wear ring.
Wherein, be provided with screw near described cylindrical wall, the capping wear ring, screw screws in the screw and can contact with wear ring.
Wherein, described capping comprises peripheral flange, and flange is provided with boss one, and boss one is provided with boss two, and cylinder is connected on the boss two, and boss one and boss two are provided with louvre.
Wherein, on the described shell bearing support is installed, bearing support comprises the holder hand on both sides, both sides holders hand respectively with shell on two lugs hinged.
Wherein, the middle part of described bearing support is provided with through hole.
Wherein, the both sides of described bearing support are provided with prong.
Wherein, described control lever is provided with resetting means, and resetting means comprises screw rod and the spring that is installed in capping, and the through hole that screw rod passes control lever is connected with spring.
Wherein, described screw rod is provided with the adjusting knob that is connected with spring.
Wherein, the openend of described shell is provided with projection, and projection is provided with contiguous block, and the contiguous block press flange just can realize being connected of capping and shell.
The invention has the beneficial effects as follows: because the capping cylinder inner wall that contacts with output shaft is equipped with wear ring, when control lever control output shaft moves, just can prevent the cylinder inner wall wearing and tearing, ensure motor energy operate as normal, prolong the service life of motor.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a perspective view of the present invention;
Fig. 2 is the part-structure schematic diagram of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, Sewing machines clutch motor, comprise shell 1, capping 2 and be installed in control lever 3 in the capping 2, in shell 1 and the capping 2 clutch is installed, clutch is connected with output shaft 4 with rotor respectively, capping cylinder 5 inwalls that contact with output shaft 4 are equipped with wear ring 6, and wear ring 6 closely cooperates with cylinder 5.When control lever 3 control output shafts move, just can prevent cylinder 5 inner wall abrasion, ensure motor energy operate as normal, prolong the service life of motor.
Wherein, described control lever 3 is connected with capping 2 by pin 7, and the through hole that pin 7 passes all is provided with wear ring 6.Wear ring 6 has been arranged, and control lever 3 just can not denuded by pin 7 easily, further prolongs the service life of motor.
In addition, be provided with screw 8 near described cylindrical wall, the capping wear ring 6, screw screws in the screw 8 and can contact with wear ring 6, tightens screw and just wear ring 6 can be locked in the closure body, prevents that it from coming off.Wherein, described wear ring 6 can cylinder iron be made, and its material is identical with bearing on the output shaft 4, is difficult to wearing and tearing when both are in contact with one another, and wear-resisting effect is relatively good.
Also have, described capping 2 comprises peripheral flange 9, and flange 9 is provided with boss 1, and boss 1 is provided with boss 2 11, and cylinder 5 is connected on the boss 2 11.So just can shorten the length of cylinder 5 as far as possible, the area that reduces wear, it is practical more reliable to ensure that the present invention uses.As a further improvement on the present invention, boss 1 and boss 2 11 are provided with louvre 12, thereby the heat that further facilitates the motor generation outwards distributes.
As a further improvement on the present invention, on the described shell 1 bearing support 20 is installed, bearing support 20 comprises the holder hand 21 on both sides, both sides holders hand 21 respectively with shell 1 on two lugs 22 hinged.There has been such bearing support 20 just can make things convenient for the present invention to be installed in the diverse location of Sewing machines, has been convenient to use of the present invention.
In order to make things convenient for the present invention to be installed on the diverse location of Sewing machines, the middle part of described bearing support 20 is provided with through hole 23.
And the both sides of described bearing support 20 are provided with prong 24, thereby from making things convenient for the present invention to be installed in the diverse location of Sewing machines to the full extent.
In order to make clutch automatically restore to the duty of connection, reduce artificial operation, described control lever is provided with resetting means, and resetting means comprises screw rod 14 and the spring 15 that is installed in capping 2, and the through hole that screw rod 14 passes control lever 3 is connected with spring 15.
