Crane reduction gears

Reduction gears are used in lifting systems and other mechanisms to increase torque and reduce rotational speed. The use of reduction gears increases the effectiveness of equipment and extends its service life. The most well-known example of reduction gears is a gearbox.

Special aspects related to crane reduction gears

A typical crane reduction gear is a metal case with shafts, worm wheels and other units. This mechanism has two special aspects:

• it can operate one-sidedly and reversibly;
• a shaft rotates in one direction with frequency of up to 1,500 rpm and not faster than 12 m/s.

In the manufacture and operation of these devices, climatic conditions are always taken into account.

Crane reduction gears can be installed on any crane equipment allowing the reversible load.

Types of reduction gears

Depending on the relative position of shafts, reduction gears are divided into:

• parallel-shaft reduction gears;
• right-angle reduction gears;
• worm reduction gears.

There are also combination-type, multi-stage and single-stage reduction gears.

The most common models are as follows:

• vertical crane reduction gears (VK) that are widely used in different types of lifting equipment;
• horizontal reduction gears (RK) that operate in the intermittent cycle and are capable of long-term operation at constant load.

Also, double-stage parallel-shaft reduction gears (RM) are often used for lifting equipment. They are very common not only in crane equipment, but also in other machine-building areas.

Main specifications

Each type of reduction gears has its own special technical aspects that are based on certain factors. The determinative aspect is the specialization of equipment.

The main specifications of reduction gears are as follows:

• capacity;
• number of gears;
• number of stages;
• gear-based connection;
• angular shaft speed;
• efficiency.

Keeping in mind these characteristics, you will never make a wrong choice. Therefore, before you decide to buy a crane reduction gear, it is recommended to carefully consider all necessary parameters.
