What Is a Helical Gear Reducer?
The helical gear reducer, commonly used in industry, is also preferred in operations requiring high speed. Due to its structure, it operates more quietly compared to reducers with spur gears. Additionally, it offers high torque and efficiency rates.
These reducers, whose gears are entirely produced in a helical form, increase efficiency, reduce wear, and improve load distribution. These products, which have multiple features, are widely used in heavy industries, transport systems, and industrial machinery.
What Is a Helical Gear Reducer?
Compared to other reducers, the helical gear reducer, which operates more quietly, provides high torque and requires low speed, has become widely used. First of all, the characteristics of these reducers are examined in terms of stages, working principle, material, and load-carrying capacity.
🟨 Material: In the manufacturing process of helical gear reducers, cast iron is generally preferred. Today, there are also varieties produced with aluminum materials.
🟨 Stages: These reducers generally start from 2 stages and can be produced up to 6 stages. The number of stages varies completely depending on the need.
🟨 Working Principle: Both gears are inclined. When these gears come into contact, they create a sliding motion and utilize friction force to provide rotational movement. The first helical gear is mounted on the rotating shaft. In this way, it receives the input power and initiates rotational motion. The second helical gear contacts the first gear and receives the input power. The process is completed by converting the received power into a low-speed, high-torque output.
🟨 Capacity: The teeth of these reducers have the same dimensions. However, thanks to longer tooth length and surface area, they provide high load-carrying capacity. Therefore, they have a more durable and long-lasting structure.
The advantages of helical gear reducers are quite diverse. While offering a wide range of applications, they stand out with their smooth gear contact feature. Low loss levels, high efficiency, production from high-quality materials, and providing suitable solutions in different fields are among the features of helical gear reducers. The gear profile of these devices and its effect on performance is also a matter of curiosity. In other words, the shape of the gear is closely related to the proper operation and safety of the reducer.
The helical gear shape refers to the appearance of the teeth in a helical form. While there is a wider contact area between the gears, it allows higher torques to be transmitted more efficiently. Therefore, the gear reducer can continue to carry larger loads. Proper gear contact means less vibration and minimal noise in the reducer. Especially in industrial applications, those seeking a quiet working environment prefer helical gear reducers.
The helical gear reducer, which distributes the force evenly between the gears, is long-lasting. Because when the force is distributed evenly, overall durability also increases. This advantage, which brings low cost, also offers a guarantee of long-term use. As a result, these devices, which are frequently preferred in industrial applications, require little maintenance and continue to operate with high efficiency.
What Does Helical Gear Mean?
A helical gear is a type of gear that generally has a cylindrical structure and inclined teeth. It operates much more quietly than spur gears and vibrates less due to the angled teeth. It is widely preferred in heavy industry and the automotive sector and can also be defined as a high-strength gear.
The tooth structure of a helical gear is not parallel to the shaft axis. In this way, the teeth come into contact gradually. This feature provides quiet power transmission and continues with smoother contact. Compared to spur gears, it has a higher load-carrying capacity. Because thanks to the inclined structure of the teeth, each tooth connects with another and distributes the load more effectively.
Helical gears, used especially in vehicle gearboxes, as well as in the food industry, power plants, and mining, offer efficient performance at high speeds. These gears, which require low maintenance, have a longer service life. Although the assembly and production process is complex, their usage area continues to expand today.
How Many Types of Gear Reducers Are There?
Gear reducers are divided into 7 classes according to gear types. These are;
🟨 Harmonic Reducer: Harmonic reducers, which have high torque transmission and precision, are preferred in automation and robotic systems.
🟨 Planetary Reducer: These reducers, which also operate at high torque, are generally preferred for applications requiring a compact design. In this type, the load of the gears is distributed and high performance is achieved.
🟨 Bevel-Helical Reducer: Combines the advantages of both helical and bevel gears. It operates with high efficiency and torque.
🟨 Bevel Gear Reducer: In this reducer, rotational motion is transferred from one axis to another. It is used for angular motion applications.
🟨 Worm Gear Reducer: In these products, rotational motion is at 90 degrees. It is used in applications requiring low speed and high torque.
🟨 Spur Gear Reducer: It is a widely used type of reducer. Rotational motion is transmitted directly to spur gears.
What Is a Gear Reducer Used For?
The purposes of using a gear reducer are as follows;
🟨 To ensure smooth operation between rotating systems
🟨 To provide a significant transmission ratio in compact dimensions
🟨 To obtain different directions of rotation
🟨 To provide power transmission between shafts located in different positions
🟨 To reduce the rotational speed of high-speed electric motors to lower speeds
The application areas of gear reducers also vary. The usage purposes and explanations of helical gear reducers are listed below.
🟨 Agriculture and Livestock: Helical gear reducers used in livestock equipment and agricultural machinery provide power transmission.
🟨 Beverage and Food Industry: These reducers are used in certain equipment in the food and beverage industry. Their purpose is to regulate production processes.
🟨 Textile: Frequently preferred in knitting and weaving machines, helical gear reducers control the movement and speed of machines. Thus, they ensure that production processes are kept under control.
🟨 Construction Machinery: Helical gear reducers are used in large construction machines. Examples include concrete mixers and cranes.
🟨 Pump Systems: These products used in pump systems ensure that fluid transfer processes are carried out regularly. They also have a wide range of use from wastewater and water facilities to industrial plants.
🟨 Cement Production: These devices, preferred in cement production plants, ensure that transportation and lifting operations continue safely. They are preferred due to their strength and durability.
🟨 Conveyor Systems: The helical gear reducer used in material handling systems regulates torque and speed control.
As seen, the prices of these reducers, which have various application areas, are also a matter of curiosity. The following factors determine the prices of reducers;
🟨 Additional Features: Some reducers may include thermal sensors, special protection classes, and lubrication systems. These factors directly affect the price.
🟨 Manufacturer and Brand: As with every product, the brand and manufacturer play an important role in determining reducer prices.
🟨 Durability and Quality: These two elements determine the price of reducers. Production standards and material quality are among the pricing factors.
🟨 Speed: The reduction ratio and speed control in the reducer naturally affect prices.
🟨 Power Capacity: Prices are higher for reducers operating at higher power levels, which are directly proportional to motor power.
