Summary of the invention
In view of the above technical problems, the present invention provides that a kind of structure is simple, at low cost and applicability is wide for reclosing
Decelerating motor.
In order to solve the above technical problems, the technical solution used in the present invention is: a kind of decelerating motor for reclosing,
It includes a motor, and a gear-box, the gear-box includes a cabinet, it is characterised in that: the gear-box further includes a setting
The worm screw of output axis connection in the cabinet and with the motor, the first gear of a sequence and the worm screw tandem sequence
Combination, second gear combination, gear and shaft coupling；One is arranged in the protrusion on the couplings outside lane, and one is provided with the tooth
Wheel inner ring and the groove that can be rotated relatively freely with the protrusion；One is arranged in the cam bit of the gear face, a setting
Sliding block on the cabinet, the cam bit drive the sliding block sliding.
The first gear combination and second gear combination include gear wheel, shaft and the pinion gear being wholely set；Institute
The gear wheel for stating first gear combination is engaged with the worm screw, the pinion gear and the second gear group of the first gear combination
The gear wheel of conjunction engages, and the pinion gear of the second gear combination is engaged with the gear.
The first gear combination, second gear combination, gear, shaft coupling material be plastics.
The protrusion and groove are sector structure, and the protrusion and groove can rotate relatively freely, and are freely turned relatively
Dynamic angular range is 30-300 °.
The head number of the worm screw is 1-3.
Gear wheel in the second gear combination is one of helical gear or turbine.
The present invention due to using the technology described above, the technical effect reached are as follows: 1. due to first gear of the invention
Combination and second gear combination are all made of integral structure, therefore, structure are simplified, to improve the precision and effect of transmission
Rate further overcomes existing the problem of time-consuming, poor reliability of closing a floodgate of traditional motor deceleration device.In addition to this,
The gear structure of integral type also overcomes user and assembles inconvenient defect.2. since the material of gear structure of the invention is adopted
Therefore the cost of decelerating motor is greatly reduced with plastics.3. the outer ring setting of the shaft coupling due to power output end of the present invention
There is a fan-shaped protrusion, and the scalloped recess that one with fan-shaped male cooperation are opened up in the gear of shaft coupling assembly, shaft coupling can be
It is freely rotated in gear, the angle rotated relatively freely is limited by fan-shaped protrusion and scalloped recess, the angle rotated relatively freely
Range is 30-300 °, therefore, can be suitable for the reclosing device that combined floodgate angle is 30-300 °, expand significantly of the invention
Applicability.4. since the lower end surface of the gear of power output end of the invention is wholely set a crescent cam bit, cam bit energy
It enough pushes the sliding block being arranged in lower cover plate groove to slide, when sliding block slides into one end far from gear, reclosing will be withstood
Thimble in device makes reclosing device cannot achieve combined floodgate, to reach the function of locking reclosing device.5. due to the present invention
Motor output shaft be arranged a worm screw, the power exported motor by worm screw is one by one through first gear combination, second gear group
Conjunction, gear, shaft coupling are transmitted to reclosing device, and the use of worm screw can be effectively prevented from traditional gear and engage existing tooth
Roller box stuck phenomenon closer can reduce noise.
