An adjustable double worm reducer

Abstract

The invention relates to a speed reducer, in particular to an adjustable type double-worm speed reducer. The adjustable type double-worm speed reducer mainly solves the technical problems that in the prior art, when the power failure or motor failure happens to a speed reducer, a motion component fixed to an output shaft of the speed reducer is possibly located at the unreasonable position, and smooth resetting cannot be achieved. The adjustable type double-worm speed reducer comprises a box body, a first-level worm is arranged in the box body, the first-level worm is connected with a motor through a motor key on a motor shaft, the first-level worm is meshed with a first-level worm gear, the first-level worm gear is connected with a worm and worm gear shaft through a key, a worm on the worm and worm gear shaft is meshed with a second-level worm gear, a worm gear hole is formed in the second-level worm gear, the second-level worm gear is connected with an output worm gear shaft through a sliding key, a sliding key clamping groove is further formed in the second-level worm gear, the sliding key can slide in a sliding key moving groove of the output worm gear shaft and the sliding key clamping groove of the second-level worm gear, the sliding key is connected with the output worm gear shaft in a penetrating mode, a compressed spring and an ejector rod are arranged on the two sides of the sliding key respectively, and the ejector rod is arranged in a through hole of the output worm gear shaft.

Description

technical field [0001] The invention relates to a reducer, in particular to an adjustable double-worm reducer. Background technique [0002] The geared motor is a power transmission device, which mainly uses gears for speed conversion, decelerates the output revolutions of the motor shaft to the required revolutions, and obtains a larger torque device. The Chinese patent discloses a deceleration motor (authorized announcement number: CN201383736), which includes a motor and a deceleration gear box fixedly connected to the motor. A gear reduction mechanism is arranged in the deceleration gear box, and a rotor and a motor output Shaft, the end of the output shaft of the motor has a tooth shape and this end is meshed with the gear reduction mechanism; the gear reduction mechanism includes a gear shaft and an output shaft arranged on the reduction gear box, and the gear shaft is connected with the primary gear through the shaft key fit, And the gear shaft is provided with a too...
