Precision servo reducer has the characteristics of small volume, high precision, small return error and high stiffness. It is widely used in robot, machine tool, medical, military and packaging and printing industries.
Important parameters of planetary reducer
Reduction Ratio: Ratio of input speed to output speed.
Series: The number of sets of planetary gears. Can achieve 3 levels most commonly, efficiency will be reduced somewhat.
Full load efficiency: The transmission efficiency of the reducer under maximum load (fault stop output torque).
Working life: the cumulative working time of the reducer at rated load and rated input speed.
Rated torque: is the rated life allowable long time of operation torque. When the output speed is 100 RPM, the life of the reducer is the average life, more than this value when the average life of the reducer will be reduced. Reducer failure when output torque exceeds twice.
Noise: Unit dB (A), this value is the input speed of 3000 RPM, without load, measured at A distance of 1 meter from the reducer.
Reducer is generally put through the motor. Internal combustion engine or other high speed operating of power on the input shaft of the reducer gear of big gear on the output shaft gear mesh less to achieve the purpose of reduction, speed reducer is a kind of used for low speed high torque transmission device, this is a question of common sense, not speak, to several common reducer are same principle gears to achieve the ideal effect, The ratio of the number of teeth of the big and small gears is the transmission ratio. Series: The number of sets of planetary gears. Because one set of planetary gear cannot meet the larger gear ratio, sometimes two or three sets are needed to meet the larger gear ratio requirements of the user. As the number of planetary gears is increased, the length of stage 2 or 3 reducers will be increased and the efficiency will be reduced. Return clearance: the output end is fixed, the input end rotates clockwise and counterclockwise, so that the input end produces rated torque +-2% torque, the reducer input end has a small angular displacement, the angular displacement is the return clearance. The unit is "minutes ", which is one-sixtieth of a degree. It is also called back gap.
