Abstract
The invention relates to an electric motor transmission structure, particularly relates to an electric motor transmission structure with a function of overload protection, and belongs to the technical field of electric motors. The electric motor transmission structure comprises an electric motor, wherein a motor gear is nested on an electric motor output shaft, and the lower end of the electric motor output shaft is connected with a locking block through a cylindrical pin; an inner locking gasket and an outer locking gasket are nested on the electric output shaft, the inner locking gasket is located on the inner side of the motor gear, and the outer locking gasket is located between the motor gear and the locking block; and a spring is nested at the upper end of the electric motor output shaft and compresses the inner locking gasket, the motor gear, the outer locking gasket and the locking block. The electric motor transmission structure is simple, compact and reasonable in structure, suitable for batch production, small in size, convenient to assemble and good in product consistency, and doesn't occupy additional space; and on the condition that normal work of the electric motor is guaranteed, the overload protection function is added, so that the motor cannot be burnt during overloading.
Description
Technical field
The present invention relates to a kind of electric-motor drive structure, a kind of electric-motor drive structure with overload protection, belongs to motor technology field specifically.
Background technology
Along with the development of machinery industry, the application of motor is more and more extensive, is replacing step by step manual operation.Yet due to various problems, motor is often because overload is burnt.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of electric-motor drive structure with overload protection is provided, guaranteeing, in electric motor normal working situation, to increase overload protection function, make motor be unlikely to burn when overload.
According to technical scheme provided by the invention; electric-motor drive structure with overload protection comprises motor; motor is provided with motor output shaft, it is characterized in that: on motor output shaft, be set with motor gear, motor output shaft lower end connects latch segment by straight pin.On described motor output shaft, be set with internal locking pad and outer locking pad, internal locking pad is positioned at motor gear inner side, and outer locking pad is between motor gear and latch segment.Motor output shaft upper end pocketed springs, spring compresses internal locking pad, motor gear, outer locking pad and latch segment.
Further, between motor and spring, be provided with pad.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, is applicable to batch production; Volume is little, does not additionally take up room; Be convenient to assembling, good product consistency; Guaranteeing, in electric motor normal working situation, to increase overload protection function, making motor be unlikely to burn when overload.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-motor, 2-motor output shaft, 3-straight pin, 4-latch segment, 5-pad, 6-spring, 7-motor gear, 8-internal locking pad, 9-outer locking pad.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises motor 1, and motor 1 is provided with motor output shaft 2.
On motor output shaft 2, be set with motor gear 7, motor output shaft 2 lower ends connect latch segment 4 by straight pin 3.
On described motor output shaft 2, be set with internal locking pad 8 and outer locking pad 9, internal locking pad 8 is positioned at motor gear 7 inner sides, and outer locking pad 9 is between motor gear 7 and latch segment 4.
Between described motor 1 and spring 6, be provided with pad 5.
Operation principle of the present invention is: after motor has assembled, and tensioned, spring compression pad and inside and outside lock washer, thus make motor gear axially be subject to a certain size power.This power makes the relative internal locking pad of motor gear, has frictional force to produce between the relative latch segment of outer locking pad.When electric motor normal working, frictional force size equals the size of motor load power, makes motor gear along with motor synchronous rotates.When motor load is excessive, this frictional force size is constant, but is less than motor load, and motor gear is no longer along with motor synchronous rotates, and motor actual loading power size still equals frictional force, and motor reality is not transshipped work, is still normal operating state.
The present invention is simple in structure, compact, reasonable, is applicable to batch production; Volume is little, does not additionally take up room; Be convenient to assembling, good product consistency; Guaranteeing, in electric motor normal working situation, to increase overload protection function, making motor be unlikely to burn when overload.
