Abstract
The invention discloses a clutch device of an electric operating mechanism for a switch and a circuit breaker. The clutch device is characterized in that a large clutch gear is provided with a lug boss A, a small clutch gear is provided with a lug boss B, and when the large clutch gear and the small clutch gear rotates synchronously, the two clutch gears are matched; a clutch rod is pressed by hands to a limit position then to a plate, then by taking a rotary hole on a clutch cover plate as a pivot and the connection with a groove neck of a gear shaft by a gap of the clutch rod, a small gear is pulled to move upwards, and a spring is extruded by an elastic retaining ring at the gear shaft, the lug boss B on the small clutch gear is separated from the lug boss A on the large clutch gear, when the clutch rod is released, the gear shaft is under the action of the spring, and the large clutch gear and the small clutch gear are separated. The clutch device has the following advantages: by the cooperation of the clutch rod and a shaft neck of the gear shaft, the gear shaft and the gear are driven to move upwards, and as the gear shaft is clutched, the periphery of the whole gear bears average force, and the device is safe, reliable and convenient to operate. The clutch device has simple structure, convenient installation and safe use and can protect the switch effectively.
Description
Technical field
What the present invention relates to is the arrangement of clutch of the motor-operating mechanism used of a kind of switch and circuit breaker.Belong to the electric operating mechanism of circuit-breaker technical field,
Background technology
In the existing technology, the gear of two mutual clutches is by adding a long depression bar gear wheel to be applied downward pressure, realizes separating, depression bar is applied downward power, after boss is stressed gear is moved down, realize separating, but owing to be monolateral stressed, cause unbalance stress, separate dangerous.
Summary of the invention
What the present invention proposed is the arrangement of clutch that a kind of switch and circuit breaker are used motor-operating mechanism.Its purpose is intended to overcome the above-mentioned defective that prior art is deposited, and guarantees to separate reliable and secure.When motor damages, motor and gear reduction box are separated, with the running of manual handle driven gear reduction box, promote the combined floodgate and the separating brake of circuit breaker or switch.
Technical solution of the present invention: it is characterized in that establishing on the big clutch gear on A boss and the little clutch gear and establish the B boss, when clutch gear wheel and little clutch gear rotate synchronously, two clutch gears are realized coincideing; The hand trip(ping) lever is to extreme position to plate, with the rotary hole on the clutch cover plate is fulcrum, gap by trip(ping) lever is connected with the groove neck of gear shaft, the pulling pinion up moves, same spring is by the extruding of the circlip on the gear shaft, makes B boss on the little clutch gear separate A boss on the big clutch gear, unclamp trip(ping) lever after, gear shaft is under the active force of spring, and big clutch gear is realized separating with little clutch gear.
Advantage of the present invention: by cooperating between the axle journal of trip(ping) lever and gear shaft, the driven gear axle up moves because gear shaft and gear are one, thereby also up motion of gear since clutch gear shaft,
Make the gear overall circumference evenly stressed, avoided the situation of monolateral unbalance stress in the background technology, so safe and reliable and easy to operate.Effectively stopped when abnormal conditions appear in switch, still continued the situation generation that operation damages switch after the motor outage.Simple in structure, easy for installation, effectively protection switch is safe in utilization.
