Description
Technical field
The present invention is a kind of bipyramid tooth mechanical differential structure, is related to a kind of deceleration mechanism, more particularly to a kind of use
Two motor drive speed difference when bipyramid tooth planetary reducer jointly, and the bipyramid tooth differential for obtaining slow-speed of revolution output subtracts
Fast mechanism.
Background technique
The retarder of articulated robot mainly uses RV retarder.RV retarder has that transmission ratio is big, output torque is big
Advantage.RV reducer structure complexity, disadvantage at high cost, also constrain the popularization and application of RV retarder.In articulated robot
In, RV retarder gradually replaces harmonic speed reducer.The flexible gear intensity of harmonic speed reducer is low, leads to harmonic speed reducer
Output torque is small, service life is short.The RV retarder articulated robot big for load torque, harmonic speed reducer turn for loading
The small articulated robot of square.Common planetary gear retarder is a kind of universal speed reducer.With RV retarder or harmonic speed reducer
It compares, the transmission ratio of planetary reducer is small, is unable to satisfy requirement of the articulated robot to transmission ratio.

Dynamic, stopping, even frequently changing the direction of rotation of its motor, these motion features make motor in the lower work of efficiency
Make to run under state.
In addition, there is also the spies that the output revolving speed and output power to motor match technical requirements under different operating statuses
Different load device.For example, the clothing weight that intelligent washing machine can wash as needed injects the liquid detergent and water of corresponding weight,
Under identical washing mode, the output revolving speed of motor be it is identical, clothes, liquid detergent and the water for needing to wash in washing machine
Total weight is not identical, then requires motor output torque when exporting same rotational speed not identical, that is, require the output work of motor
Rate is not identical.If motor cannot adjust the output power of motor, the motor of the washing machine when exporting same rotational speed
Still it is not run under the higher working condition of efficiency.
If having the advantages that, a kind of deceleration mechanism is big with transmission ratio, output torque is big, and the motor drive deceleration mechanism connects
Continuous rotation, and when keeping motor direction of rotation constant, deceleration mechanism driving load device can be realized operation, stopping,
And changing the function of load device direction of rotation, then the deceleration mechanism can ensure motor in the higher working condition of efficiency
Lower operation, and response speed is improved when the deceleration mechanism changes load device direction of rotation.If two motor can be same
When adjust motor output revolving speed and output power, keep two motor drive deceleration mechanisms speed difference it is constant
Under the premise of, while improving the output revolving speed i.e. raising simultaneously for perhaps reducing by two motor simultaneously or reducing by two electricity simultaneously
Motivation drives the output power of the deceleration mechanism, then the deceleration mechanism meets specific loads device requirement motor and can export
The control requirement of output power of motor is adjusted when same rotational speed.
