Introduction of helical gearbox

Helical Gearbox is one of the useful types of gearboxes in various work processes, which is also known by other titles such as direct shaft gearbox, ball helical gearbox, three-axis gearbox, etc. In the design of these gearboxes, shafts, gears, etc. are used, which are placed inside a strong shell. The shaft is made of steel and the shell of these gearboxes is made of cast iron or steel.

The design of these gearboxes is done in several stages depending on the model and the distance transmission they have. In the design of some of these gearboxes, a pair of perpendicular gears are used, which can change the direction of the input torque by 90 degrees. In the structure of these gearboxes, spiral bases are used and their installation is done horizontally and vertically through these bases. The characteristics of these gearboxes include high output torque, high durability, high density and low noise performance.

Types of helical gearboxes

Helical gearboxes are produced and supplied in different types and models due to their design and usage, including single-stage, two-stage, three-stage, base, flanged, base and flanged helical gearboxes. , compound, double shaft and hollow shaft pointed out. In the following, we will introduce and review each of these models.

Single stage helical gearbox

The single-stage helical gearbox is one of the practical models of the gearbox, in which the output shaft of the device rotates against the direction of the input axis. The features of these gearboxes include their simple design and strong performance. These devices are mostly used for conditions requiring high output revolutions and output torque in the range of 36 to 830 Nm. These gearboxes are specially used in fans, blowers and pumps.

Two-stage helical gearbox

The two-stage helical gearbox is another type of gearbox, and it is used to reduce the gear between the input and output shafts in two stages. The process of power transmission in these devices is done through helical gears. The double gears used in the design of these devices, which are spiral, have all the advantages of spiral gears, which include their high power and very low noise.

Three-stage helical gearbox

The three-stage gearbox is one of the other types of helical gearboxes, and as its name suggests, the process of increasing the torque takes place in three stages. In the first stage of the gear, the torque caused by the input shaft is doubled, and in the second stage of the gear, this increase in torque is doubled, and finally, in the third stage of the gear, this torque will be tripled.

Helical gearbox with base

Among the other models of these gearboxes, we can mention their base model, which is standardly used to install these gearboxes in horizontal mode. The base designed for these gearboxes is usually one piece with the original skin and the same material.

Helical flanged gearbox

Flanged gearboxes are another type of helical gearboxes that use flanges in their design. The flange section of these gearboxes can be used to install them vertically. The material of the flange of these devices is usually the material of their main shell, which has high strength and durability.

Helical gearbox with base and flange

In this model of gearboxes, as their name suggests, the base and flange are used so that they can be installed as standard in both horizontal and vertical positions. Of course, the flange part of these devices is not useless in the horizontal installation mode and it can be used to stabilize the device as much as possible.

Double helical shaft gearbox

Another widely used type of helical gearboxes is the two-end shaft model of these devices, which are usually produced with the design of the VEM brand. These gearboxes can be used in equipment that requires high output torque. Other features of these gearboxes include their high efficiency and low noise pollution, which makes them widely used. Also, these gearbox models can be used in working conditions that require precise control of speed and torque.

Compound helical gearbox

Composite helical gearboxes are other types of gearboxes that are used to achieve 1-16 revolutions per minute. For this, at least two helical gearboxes are required to be combined. These gearboxes are used in many fields of work, including their use in various models of conveyors, industrial silo equipment, dam valves, cutters, and the paper industry.

Helical hollow shaft gearbox

The helical hollow shaft gearbox is another practical and widely used model of these devices, which is used in many industries. Due to the hollow shaft feature of these gearboxes, it is easy to couple them with all kinds of electric motors. Another advantage of these gearboxes is their easy maintenance, which has made them widely used.

Advantages of helical gearbox

Working with helical gearboxes has many advantages due to their design and structure, which we will examine in this section. The rotation of the output axis of these gearboxes is less than the rotation of their input axis, which can be an important advantage for these devices; Because this feature multiplies the output power of these devices compared to their input power. Another advantage of these gearboxes is their design in two flanged and flangeless models, which can be used according to the needs and working conditions.

Other advantages of these devices include their high strength and durability, which makes them usable in different working conditions, especially in heavy industries, and for a long period of time. The high torque of these gearboxes is one of their other advantages, which makes them used in many work fields. Also, the tension and vibration of these gearboxes are low and produce minimal noise pollution during operation. Other advantages of these gearboxes include high efficiency, low depreciation, easy lubrication and hassle-free maintenance.

In the general definition of helical gearboxes, the Premium-transmission website states that: helical gearbox; Helical gears have teeth that are at an angle to the shaft. This results in more than one tooth contacting during operation, which allows the gear to carry more load. Because of the load sharing between the teeth, this arrangement allows helical gears to run smoother and quieter than other gears.

Application of helical gearbox

Helical gearboxes are used in many fields of work due to their many features and advantages, including the use of these devices in heavy industries. Also, due to their high strength and durability, these gearboxes can be a suitable option for industries where repairing and replacing the gearbox will be a costly process.

Among the industries in which helical gearboxes are used are food industries, pharmaceutical industries, packaging industries, cement industry, steel industry, tile and ceramic industries, marine industries, water and sewage industry, agricultural industries, petrochemical industries. , oil and gas industries, etc. Other applications of these gearboxes include their use in conveyors, mixers, etc.
