Gear reducer

Reduction Gear

A reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. 

Reduction gear assembly consists of a set of rotating gears connected to a wheel work. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, wherein the motion or torque is changed. 

What are the different types of gear reducers?

Each gear reducer has its advantages and disadvantages. You will have to choose the one that’s the most adapted to your intended use.For example, if you are looking for a good level of efficiency, perhaps you should consider a planetary gearbox rather than a bevel gear reducer.

C

Planetary Gearbox

One of the main characteristics of a planetary gearbox is the coaxial assembly. This type of assembly means that planetary gearboxes are compact.

C

Worm Gearbox

Worm gearboxes have perpendicular input and output shafts. They are generally used for applications requiring a very high transmission ratio.

C

Gear train Gearbox

The simplicity of their technology will allow you to save on maintenance costs. Additionally, gear train gearboxes have a very high performance level, close to 1.

C

Bevel Gearbox

Bevel gearboxes’ main characteristic is their angular bell crank, which allows the user to change the machine’s rotation system. 

Some Questions About

Gear Reducer

 

How to choose a gearbox which meets our requirement?

You can refer to our catalogue to choose the gearbox or we can help to choose when you provide the technical information of required output torque, output speed and motor parameter etc.

What information shall we give before placing a purchase order?

b) Housing color.
c) Purchase quantity.
d) Other special requirements.

What industries are your gearboxes being used?

Our gearboxes are widely used in the areas of textile, food processing, beverage, chemical industry,escalator,automatic storage equipment, metallurgy, tabacco, environmental protection, logistics and etc

What is your advantages?

1. Manufacturer,the most competitive price and good quality.
2. Perfect technical engineers give you the best support.
3. OEM is available.
4. Rich stock and quick delivery.

What's your products' competitive edge?

Professional engineers for your design, drawing, ensure the quality of production if non-standard products.

What is the selection criteria for choosing a gearbox?

Before buying a gear reducer, it’s important to take several factors into account.
A gearbox is used to adapt the characteristics of the input and output axis of a mechanism.
It is therefore appropriate to ask yourself about the torque first and foremost.A reducer increases the torque of your motor and thus allows a receiving member to rotate under the impact of a new torque.

Gearbox manufacturers sometimes indicate the minimum and maximum torque that can be supported by each of their products. The torque density varies according to the gear reducer. For example, planetary gearboxes have a high torque density.

 

The other purpose of a gearbox is to reduce the motor speed and we recommend that you take into account the ideal reduction ratio for your use. Based on the rotational speed of your motor, the reduction ratio is used to determine the output rotational speed. This information is also indicated by manufacturers on their product pages. It is given in revolutions per minute.

Advantages

For high precision gears, the transmission efficiency is very high. 

When properly lubricated, it can be used for a long time.

Can be produced relatively cheaply as standardized gears are used.

Gear reducers with spur gears are used for increasing speed.

When should you use a gear rudecer?

planetary-gearbox

Planetary Gearbox

Using  planetary gearboxes for applications requiring strong accelerations as well as for applications with a slow speed but high torque. They are also widely used for machining centers and other machine tools, and mobile machinery used in public and agricultural works.

Worm Gearbox

Worm gearboxes are less expensive than planetary gearboxes and are also quieter. Worm gearboxes do not vibrate, so they generate little noise and are more comfortable to use.You choose this type of technology for conveyors, winches and handling.

Gear Train Gearbox

Gear train gearboxes with parallel axes are generally used for applications requiring a lot of power, such as conveyors.The simplicity of their technology will allow you to save on maintenance costs. Additionally, gear train gearboxes have a very high performance level, close to 1.

How to calculate the dimensions of your gear reducer?

In order to calculate the dimensions of your gear reducer, you will need to choose the right shaft. There are three different shaft orientations: orthogonal, coaxial and parallel.

If a gear reducer has an orthogonal shaft orientation, the input and output shafts are perpendicular. This is often the case for bevel gear reducers and worm gear reducers. Orthogonal shaft orientation is also used in industrial installations and differential automotive bridges.

If a gear reducer has a coaxial shaft orientation, the input and output shafts are aligned. This is the case, for example, for planetary gearboxes or gear reducers used in engines and turboprop engines used in the aeronautic industry.

If a gear reducer has a parallel shaft orientation, the input and output shafts are parallel.
