The gearbox is one of the power transmission factors. The helical gearbox is one of the types of gearbox that is widely used in the industry. Now the question arises, what is a helical gearbox?

The helical gearbox is one of the most widely used types of industrial gearboxes. This gearbox is also known as 90 degree gearbox in the market. The main components of this gearbox are Mardon and gears, which are made of steel or brass. Other components include shafts, bearings and spherical hubs. The mechanism of action and transmission of power in the helical gearbox is done by engaging the axis and the spiral gear with each other. The design of this gearbox and various installation methods have caused its repeated use for various purposes.

Helical gearbox function
It should be said that the function of the helical gearbox is such that with each 360 degree rotation, the engaged gear rotates one tooth. For machines with multiple power sources, the gear ratio is proportional to the number of gear teeth. The rolling and sliding movements engage the gear and mandrel and finally transfer power to the output shaft. The sliding motion is more noticeable when the conversion ratio is high.

Helical gearbox heating
Most of the heating of the worm gearbox is due to the friction caused by the sliding movement of the shaft and the gear. This friction limits transmission efficiency to between 30 and 50 percent. Normally, when designing worm gears, the material of the hub and the gear are selected from two different metals to reduce friction and increase efficiency. The internal components of the helical gearbox are called helical gears. Helical gears were first discovered and used by Archimedes. This type of gearbox, like industrial gearboxes, etc., is responsible for changing the speed and torque according to the user’s needs.

Types of helical gearboxes
The types of helical gearboxes are:

VF series helical gearbox
Cubic / manual gearbox
VF series helical gearbox
This type of gearbox, which is also known as manual helical gearbox or small gearbox, has a shaft at the input end (connection to the engine). The type of gearbox can move in two ways. In the first case, a flywheel and human hand power are used to move the gearbox. Manual transmission has low speed, high precision, low friction and low noise. One of the disadvantages of this series is the low torque due to its manpower. Another type of VF series worm gear reducer uses electric motor power. These types of gearboxes are indirectly connected to the electric motor using a clutch, coupling, belt, etc.

Cubic / manual gearbox
Cubic / manual gearbox is a gearbox, which is also called a manual gearbox. It includes Mardon and Cube gears. Cube gearbox or manual gearbox is actually a type of helical gearbox. This product, like a spiral gearbox, increases the output torque or power and decreases the number of engine revolutions.

This gearbox has many advantages, including very high efficiency, long life, reasonable price, low noise, very high reliability factor, etc. These products are made in such a way that you can use them 24 hours a day without interruption. use. The round-the-clock operation of this gearbox has a positive effect on the work process of many industries.

What is the application of helical gearbox?
Helical gearboxes are widely used in the industry. Helical gearboxes are widely used in cars. The rotation of the helical gears causes the bearing balls to rotate again, which reduces the frictional forces, resulting in better control of the wheels. This release results in better machine control and reduced wear, which improves steering precision. Small helical gearboxes are actually used to reduce rotation speed and increase torque. Small electric motors are suitable for high speed and low torque applications. By increasing the number of gears, the application range of the gearbox can be expanded.

Application of helical gearbox in industries
Worm gearboxes are used in presses, material conveyors, metal rolling mills, mining equipment, chainsaws and guide equipment.
Additionally, mills and rotary tables use a very precise worm gear that is capable of transmitting a small amount of backlash.
Helical gearboxes are used in many elevators. Due to the small dimensions and irreversibility of this model of gearboxes, their use in elevators is very affordable.
Helical gearboxes are widely used in the transportation industry. In sailing ships, this equipment is used to control the direction of the ship.
Previously, human power was used to replace the ship’s sails, which is very difficult to replace due to the size of the sails. It is very easy to change the direction of sails using worm gears.
The differential of most cars is controlled by helical gears.
Helical gears are used to tune many musical instruments, including guitars.
Worm gear motors are widely used in conveyors and small material handling systems such as tile and ceramic factories.
The reason for the widespread use of helical gearboxes
Helical gearboxes have many applications due to their design and output angle, due to their orthogonality, and due to their smooth operation, they are widely used in lifting systems and elevators that require torque production and soft start.
