Helical Gear Reducer:

For SR geared reducers, the boxes are cast precisely by high steel material and processed at pricessing center; the gears are made of high-quality alloy steel, are treated with surface hardening and gear ground; and the key parts are imported. The whole geared motors are small in volume, with great load-carrying capacity, steady running, low noise and high efficiency. SR geared motors have reached the advance international level, can replace the same kind of products imported.

Equipment method:

1. Foot installation

2. Flange installation

3. Flange installation with extended bearing case

4. Various of motors or double shafts can be equipped

Technique parameter:

1. Power:   0.12 KW~160 KW

2. Torque:  85 N.m~18000 N.m

3. Ratio:    1.4~28000

Guidance for model selection:

1. Determinging the service factor fB

    Before determining the service factor fB, you should first confirm the daily operating time, the starting and stoping times of every hour and the load classification. In which, the load classification is calculated according to the following formula:

    Load classification:

        a.) Uniform load, permitted mass acceleration factor ≤0.2

        b.) Moderate shock load, perimitted mass acceleration factor  ≤3

        c.) Heavy shock load, perimitted mass acceleration factor  ≤10

    When permitted mass acceleration factor more than 10, please contact with our company.

Mass acceleration factor= (All external mass moments of inertis)  / (Mass moment of inertia on the motor end)

Service factor fB:

fB=(Mamax*n_a) / (Pm * 9550)

In this formula:

Mamax = maximum permissible output torque (N.m)

n_a
