Abstract

The utility model relates to a dual supply automatic transfer switch's motor drive for dual supply automatic transfer switch is under automatic program control, and the torque moment of motor output transmits a subassembly of shifter, and the output shaft other end of this mechanism one end is continuous the motor is continuous the main shaft of shifter, changes the rotatory axial of motor through the many connecting rods of this mechanism. The mechanism is a four-bar mechanism, and is automatically locked at two limit positions while transmitting torque, so that the limit of in-place closing is realized.

Description

Motor transmission mechanism for dual-power automatic transfer switch

Technical Field

The utility model relates to a motor drive mechanism for dual supply automatic transfer switch belongs to electrical apparatus technical field.

Background

The dual-power automatic transfer switching device realizes the automatic transfer of two paths of power supplies, the motor drive is a frequently used mode, the motor outputs low-speed torque through gear reduction, when the output shaft of the motor is not consistent with the axial direction of the main shaft of the transfer mechanism, a mechanism capable of changing the axial direction and transmitting the torque is needed, and the dual-power automatic transfer switching device is characterized by being simple and reliable.

SUMMERY OF THE UTILITY MODEL

The utility model provides a motor drive mechanism for dual supply automatic transfer switch, this kind of motor drive mechanism constitute a module, including the riveting axle of first connecting rod, second connecting rod, third connecting rod and three kinds of connecting rods of connection, driving motor's output shaft exports the second connecting rod through the rotatory moment of first connecting rod, and the rotatory output moment of second connecting rod arrives the third connecting rod, and third connecting rod output moment arrives on the shifter main shaft.

The utility model discloses a middle trompil size of first connecting rod is the close fit shape unanimity with motor output shaft, and first connecting rod can be rotatory with the same rotational speed of motor shaft, and first connecting rod has the effect of connecting the motor shaft, can accept the output torque of motor.

The utility model discloses a round hole on first connecting rod both sides links to each other through riveting the axle with the second connecting rod, and the second connecting rod passes through the riveting axle with the third connecting rod again and links to each other, and the second connecting rod is the midbody of transmission moment, is linking to each other first and third connecting rod, through riveting first and third connecting rod of hub connection, and its length of second connecting rod is too long and too short can not rotate.

The utility model discloses a moment transmission of second connecting rod is accepted to the third connecting rod, and the trompil is unanimous with the main shaft shape of shifter in the middle of the third connecting rod.

The utility model discloses when first connecting rod rotate to be less than 5 with second connecting rod and third connecting rod contained angle, form the auto-lock state, third connecting rod output torque no longer, at this moment dual supply automatic transfer switch's motor drive will lock and die, can protect the shifter not to destroy.
