Abstract
The utility model relates to an electromotor operating mechanism of a power supply change-over switch with a clutch, which belongs to the technical field of a low-voltage motor. The clutch comprises a coil 3, a clutch shaft 4, a friction sheet 5, a driven disk 6, springs 7 and a brake disk 8, wherein the coil 3 is positioned in the clutch, and the friction sheet 5 is positioned at the upper end of a rotary shaft of the motor; the rotary shaft 2 of the motor is positioned at and is closed with the lower part of the clutch shaft 4, and the brake disk 8 is positioned at the uppermost end of the clutch shaft and is supported by two pressure springs 7. With the addition of the clutch, the control of the electromotor operating mechanism is simplified by the control of the clutch, and the misoperation of the operating mechanism, which results from the inertia of the motor, is avoided.
Description
Technical field
The utility model relates to a kind of electric motor operating mechanism that has the transfer switch of clutch, belongs to the low voltage motor technical field.
Background technology
Electric motor operating mechanism generally is used for the transfer switch of three positions.The type change over switch has two positions of connecting two road circuit and an open circuit respectively, can connection, disjunction and change-over circuit (power supply or load), and to reach the purpose of power failure, power supply and change-over circuit (power supply or load).In the distribution system of supplying with important power consumption equipment, transfer switch provides the duplex feeding power supply for it, to guarantee the continuity of important power consumption equipment power supply.
Summary of the invention
The purpose of this utility model is to provide a kind of electric motor operating mechanism that has the transfer switch of clutch, by the control of Clutch Control simplification electric motor operating mechanism, avoids because the inertia of motor causes the misoperation of operating mechanism.
For achieving the above object, the technical solution of the utility model is: set up a clutch on the transfer switch, this clutch comprises motor rotary shaft, clutch shaft, coil, friction plate, clutch plate, brake disc, be positioned at the outside of clutch, motor rotary shaft be positioned at off normal in the outside of clutch shaft and its near, brake disc is positioned at the top of clutch shaft and uses by two compression springs and support.Above-mentioned parts have constituted clutch device on shaft of motor.
The beneficial effects of the utility model:,, avoid having certain economic benefits because the inertia of motor causes the misoperation of operating mechanism by the control of Clutch Control simplification electric motor operating mechanism owing to increased by a clutch.
Description of drawings
Accompanying drawing 1 is the cutaway view of the electric motor operating mechanism clutch engagement state of the transfer switch that has a clutch of the present utility model;
Accompanying drawing 2 is the electric motor operating mechanism clutch and the cutaway view motor off-state that has the transfer switch of clutch of the present utility model.
Embodiment
Below in conjunction with drawings and Examples to the electric motor operating mechanism that has the transfer switch of the clutch of the present utility model detailed explanation of making comparisons.
With reference to Fig. 1, this is the cutaway view of the electric motor operating mechanism clutch engagement state of the transfer switch that has a clutch of the present utility model.
As shown in the figure, 1 is that motor, 2 is that motor rotary shaft, 3 is that coil, 4 is that clutch shaft, 5 is that friction plate, 6 is that clutch plate, 7 is that spring, 8 is a brake disc, coil 3 is positioned at the inside of clutch, friction plate 5 is positioned at the motor rotary shaft upper end, motor rotary shaft 2 is positioned to off normal and is positioned at the top of clutch shaft near, brake disc 8 and with two compression springs supports in the bottom of clutch shaft and its.
With reference to Fig. 2, this is the cutaway view of the electric motor operating mechanism clutch off-state of the transfer switch that has a clutch of the present utility model.
As shown in the figure, after obtaining operational order, the coil 3 of motor 1 and clutch is switched on simultaneously, motor rotates, clutch adhesive under the effect of suction simultaneously, make clutch plate 6 press friction plate 5, the torque of motor 1 is passed to clutch plate 6 through motor rotary shaft 2, friction plate 5, passes to operating mechanism again.This moment, clutch was in engagement state (referring to Fig. 1), and the kinetic energy of motor is passed to operating mechanism continually.
Under the operating mechanism operation, transfer switch is transformed into another service position from a service position, and send the working power of signal cut motor and clutch, clutch drives clutch plate 8 under the effect of spring 7, separate with friction plate 5, meanwhile brake disc 8 is started working, and with clutch plate 6 brakings, clutch plate is stopped operating rapidly.And motor 1 still keeps rotating owing under the action of inertia at this moment, but because clutch is in released state, the torque of motor 1 can not be passed to operating mechanism, avoids the misoperation of operating mechanism, makes the accurate positioning of transfer switch service position errorless.
Though the utility model is described with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the utility model; should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; so be not that conduct is to qualification of the present utility model; as long as in connotation scope of the present utility model, to the variation of above-described embodiment, the protection range that distortion all will fall into the utility model claim.
Claims (2)
1, has the electric motor operating mechanism of the transfer switch of clutch, comprise motor rotary shaft, it is characterized in that: on motor rotary shaft, connect a mechanical clutch.
2, the electric motor operating mechanism that has the transfer switch of clutch as claimed in claim 1, it is characterized in that: described mechanical clutch comprises coil (3), clutch shaft (4), friction plate (5), clutch plate (6), spring (7), brake disc (8); Coil (3) is positioned at the inside of clutch, and friction plate (5) is positioned at motor rotary shaft upper end, motor rotary shaft (2) be positioned at off normal in the bottom of clutch shaft with its near, brake disc (8) is positioned at the top of clutch shaft also to be supported with two compression springs (7).
