Talking about reducer terminology and specifications

Now, customers order a type, and then the manufacturer organizes production according to the type provided by the customer.I list a type: R77-32.72-Y2.2KW-4P-M1-0°, where R77 is the type of reducer, 32.72 is the reducer, 2.2 is the motor power, 4P is the 4th grade motor, 2.2KW is 1420 rpm, M1 is the mounting method, and 0° is the orientation of the motor junction box.Let me explain how to point out the relevant terms in English and Chinese.

Reduction ratio: The ratio of the input speed to the output speed is the number of input revolutions divided by the number of output revolutions, represented by the letter i.

Number of stages: The reducer has several sets of gears and is usually called a multi-stage transmission.Taking the four main series of R series reducers as an example, the RX series is a one-stage gearbox with only one set of gears.R-series gear ratios below 18 are two-stage gearboxes, that is, two sets of gears.When above 18, use a three-stage transmission, that is, three sets of gears, but the 18 speed ratio is not absolute.I'm just saying a similar value, other types of sequences not mentioned first;

Full load power: the transmission power of the reducer under the condition of maximum load (stop output torque is defective); the power of the hard gear reducer is almost 95%, and the power of the turbine is 65%, indicated by the letter FB.

Working life: the cumulative working time of the reducer under additional load and additional input speed;

Extra Torque: Guaranteed long life is long working torque.When the output speed is 100 rpm, the life of the reducer is the average life.When it exceeds this value, the average life of the reducer will decrease.When the output torque exceeds twice, the reducer fails.Letter Nm means; F series reducer

Noise: Unit decibel dB (A), this value is the measured value when the input speed is 1500 rpm, no load, and the interval between the reducers is 1 meter;

Reverse play: input is fixed, output rotates clockwise and counterclockwise.When the output is subjected to an additional torque of plus or minus 2%, the output of the reducer will have a slight angular displacement.This angular displacement is the return clearance..The unit is 'arc minutes', which is 1/60 degree.Planetary reducer

The above briefly introduces the relevant terms and codes of the reducer.I wish we had a better understanding of reducers.
