Types of Universal Speed Reducers

speed reducer gearbox design 4

Universal gear reducers come in different arrangements, ratios, and designs. Depending on the application or the industry to use it for, the right speed reducer to go for may depend on the equipment’s specific need, space availability, and ratios.

Here are the two of the most common types of universal gear reducers:

6:1 Universal Speed Reducers

A 6 to 1 gear reduction box is achieved when a two-gear setup such as a 78-tooth input gear engages and drives a 13-tooth output gear. Similarly, this gear ratio could indicate reduced motor speed from 3,600rpm to 600rpm. The 6:1 speed reducer can cover heavy-duty applications, such as generators, pumps, and other industrial equipment.

2:1 Universal Speed Reducers

The 2 to 1 gear reduction box is equipped with a two-gear setup which may have a 26-tooth input gear that engages and drives a 13-tooth output gear. This gear ratio also indicates the reduced motor speed from 3,600rpm to 1,800rpm.

The 2:1 Universal Speed Reducers are applicable for a wide range of heavy-duty applications, such as welders and other industrial equipment that require high torque at a lower RPM.

How to Choose a Universal Speed Reducer

In contrast to the more specific and special gear reducers, a universal speed reducer, as the name implies, is universal in shape, size, and mounting position to fit the requirements of most machinery.

The universality of this speed reducer gearbox design makes it more intricate, as several parts must be included to meet the needs of almost every piece of equipment. Because of this, it’s crucial to consider several factors when choosing the right gear reducer unit.

Selection of Gear Units

The selection of gear units depends on the application and industry demands. Here are the primary factors to consider to make a proper speed reducer and gearbox reducer for electric motor selection:

1. Availability of space for installation – Space availability is determined by the size and type of gear reducer and the required installation position. A small gear reduction box is recommended if not much space is available.

2. Efficiency needs – Certain gear units operate with much lower efficiency, so it is necessary to define the requirements.

3. Smooth performance – The demand for smooth acceleration, peaceful and quiet performance.

4. Self-locking requirement – Prevents interchangeability of the input and output gears in a setup.

5. Mounting position – This defines the position of holes to apply lubricant and place needed bolts, such as a breather valve.

6. Thermal power capacity – The thermal power capacity should be considered, especially for the gearbox reducer for an electric motor. Selecting gearboxes with increased thermal capacity makes the product less sensitive to high temperatures.

Geometrical Considerations

Selecting the right gear reducer requires geometrical considerations. Factors to consider are the housing, geometry of input and output shafts, the rated torque, speed, horsepower, and the resistance to the environment and routine usage required by the application or industry.

Reduction Ratio

The reduction ratio, the transmission or gear ratio, indicates the output rotational speed based on the motor’s input rotational speed. There are two types of gear ratios for the universal type speed reducer: 6 to 1 gear reduction box and 2 to 1 gear reduction box. Moreover, the gear ratio shows how much torque is lost or gained.


The torque, expressed in Newton meters (Nm), is generally a measurement of the force that causes an object to rotate. A universal speed reducer’s rated torque is the highest that can be transmitted constantly through the output shaft. Depending on the selected universal gearbox unit, the torque density varies.

Gear Reducer Assembly

Selection of the appropriate gear reducer assembly depends on the application or the device’s intended operation. Because of their universality, the assembly of gear units may be more specific and complex for universal gearboxes. For instance, gear reducers with vertical shaft configuration may require more complicated assembling.

Service Life

The service life of a universal type gear reducer indicates the lifespan for which the reducer can continuously function in normal conditions without declining its operating characteristics until it eventually wears out. Proper selection of speed reducer is attained with gearbox service life considered.

How can you figure out your gear reducer's dimensions?

Choosing the right shaft is essential to calculate the dimensions of a gear reducer. To start, there are three most common shaft orientations: coaxial, parallel, and orthogonal.

A gear reducer with a coaxial shaft orientation means it has aligned input and output shafts. As the name suggests, parallel shaft orientation has parallel input and output shafts. And lastly, orthogonal shaft orientation has perpendicular input and output shafts.
