How To Pick The Best Gear Reducing Mechanism

An automated device known as a gear reducer connects a motor to a driven load. It's also known as a gearbox. It allows you to adjust a motor's speed and torque in proportion to a load. Numerous gears make up a reduction gear assembly. The gear reduction ratio, or the number of teeth separating the input and output shafts, is also known as the transmission ratio.It goes without saying that picking the appropriate gear reducer is essential. Therefore, we'll discuss the numerous elements to take into account while selecting a gear reducer in this blog.

Conditions For Choosing A Gear Reducer

Several factors need to be taken into account when buying a gear reducer. A gear reducer is frequently used to alter the input and output axes of a mechanism's attributes (speed and torque). You need to be mindful of both the torque and rotation speed because of this.

The torque should therefore be the first thing you check. A reducer increases the torque of your motor, which enables a receiving part to spin under the effect of an additional torque. The minimum and maximum torque (expressed in newton meters, or N.m.) that each of their gear reducers can withstand may be specified by the manufacturer. The gear reducer has an impact on the torque strength. For instance, planetary gears have a high torque intensity.

Lowering motor speed is another purpose of a gear reducer, thus we advise you to think about the best reduction ratio for your application. Depending on the motor's rotational speed, the reduction ratio is used to determine the output rotational speed. These details are also available on the product websites of the manufacturers. Rotations per minute are used to measure it.

Finally, take into account the kind of gear reducer component that is best for your application. The input and output shafts of your gear reducer could be coaxial, parallel, or even orthogonal. Your intended use will determine this.

The Various Types Of Gear Reducers

There are four basic kinds of gear reducers available: planetary gear reducers, bevel gear reducers, gear train gear reducers, and worm gear reducers. Bevel gear reducers are the most common type. Every gear reducer has a unique combination of advantages and disadvantages that come along with it. You have no choice but to go with the alternative that will be most effective in completing the work at hand.

For instance, if you want to increase the efficiency of your system, you should use a planetary gearbox or parallel helical gearbox rather than a bevel gear reducer. You can find more information about these gearboxes here.

When Is It Ok To Use A Planet Gearbox?

A planetary gearbox's coaxial assembly is one of the most defining characteristics that set it apart from other types of gearboxes. As a result of the way they are configured, planetary gearboxes almost always have a form factor that is extremely compact.

Planetary gears have many advantages, some of which are their small size, high efficiency, low clearance, and high ratio of torque to weight. Planetary gears also have a low clearance. On the other hand, in order to maintain it properly, you will need to hire an expert due to both the high cost of the product and the complexity of its design.

Planetary gears are required for applications in robotics that demand high accelerations at low speeds as well as applications in industrial rotary furnaces that require low speed but high torque. Both of these kinds of applications are necessary for the robotics industry. In both of these categories of applications, significant amounts of torque are required. They are used extensively in machining centers and various other kinds of machine tools, in addition to mobile machinery used for a range of tasks, such as public and agricultural work.

When Should You Use A Worm Gear Reducer?

Input and output shafts of worm gear reducers are parallel to one another. They are frequently used in circumstances where a very high transmission ratio is required.

The mechanism of a worm gear reducer is not reversible. This suggests that the worm wheel cannot move the worm. This non-reversible method has the advantage of giving the system a better level of security.

Planetary gearboxes are far more expensive, while worm gear reducers are much quieter. Worm gear reducers are quieter and more enjoyable to use because they don't actually vibrate.

Worm gear reducers also come in a variety of performance levels. By combining your worm gear reducer with other gearboxes and gear trains, you can improve its performance. Conveyors, winches, and handling should all use this kind of technology.

When Is It Appropriate To Use A Gear Train Gear Reducer?

Reducers that have parallel shaft gear trains are frequently utilized in high-power applications such as conveyors. You will be able to lower the amount of money you spend on maintenance thanks to the simplicity of their technology, which will allow you to save money. In addition, the performance level of gear train gear reducers is nearly comparable to that of 1. Each and every gear train incorporates a sliver of a reduction ratio into its design.

When Is It Appropriate To Use A Bevel Gear Reducer?

The angular bell crank, which permits the operator to change the machine's rotational pattern, is the key component of bevel gear reducers. This makes it possible to switch from a transverse to a longitudinal rotating system.

The size of bevel gear reducers is tiny. They can withstand a lot of power and are fairly sturdy. They can be utilized with synchronous or asynchronous servomotors as well as three-phase asynchronous motors due to the strength of their teeth.

However, they continue to perform less well than planetary gearboxes. Bevel gear reducers are incredibly expensive and labor-intensive to maintain.

High-powered conveyors frequently use bevel gear reducers, but they are also common in mobile machinery used in public works or agricultural.

Measuring Your Gear Reducer's Dimensions

Selecting the appropriate shaft is the first step in determining the size of your gear reducer. The options for shaft orientation are orthogonal, coaxial, and parallel.

If a gear reducer has an axial shaft orientation, its input and output shafts are perpendicular. This frequently occurs with worm and bevel gear reducers. Orthogonal shaft alignment is used in differential car bridges in addition to industrial applications.

If a gear reducer has a coaxial shaft layout, the inlet and outlet shafts are lined up. This is valid, for instance, for planetary gearboxes or gear reducers used in turboprop and aviation engines. If a gear reducer has a parallel shaft orientation, the input and output shafts are parallel.


Without the use of a gear reducer, it is impossible to realize the full potential of the mechanism's efficacy and efficiency. Because of this, it is of the utmost importance to select a company that not only carries the appropriate gear reducer, but also carries products that are of a high quality.
