In heavy industries, refineries, power plants, mines and large production lines, parts with high precision and high strength play a vital role. One of these parts is the long gear shaft. These types of shafts are designed to transmit torque and power over long distances and must have high machining accuracy in addition to mechanical resistance.

In Tehran, various companies are active in the field of turning and manufacturing of industrial parts, but the brand Novin Garhab Sazan is known as one of the most reliable collections in the field of manufacturing long gear shafts in Tehran. Using precise devices and modern engineering knowledge, this collection produces parts that are used in various industries of the country.

Definition of long gear shaft

Long gear shaft is a type of steel shaft on which teeth are cut to transfer power from one part of the system to another. The main feature of this type of shaft is its long length compared to the diameter, which makes it able to transmit power between two industrial mechanisms. These shafts are usually used in heavy machinery, turbines, large industrial gearboxes, rolling equipment and cranes.

The primary materials used in them are usually alloy steels resistant to bending and twisting, such as CK45, 42CrMo4 and ST52, which after heat treatment, have a very high resistance to wear and impact.

The importance of precise manufacturing of long gear shaft

Any small error in the construction of long shafts causes imbalance, vibration, rapid wear of bearings and even component failure. For this reason, the process of long gear shaft manufacturing in Tehran must be done with very high precision. The Novin Garib Shazazan collection has the ability to produce shafts with an accuracy of hundredths of a millimeter by using CNC lathes with long cutting length and industrial stone axis equipment.

Accuracy in balance, smoothness of the surface, hardness and alignment of teeth are factors that guarantee the quality of shaft performance. In the modern workshops of gear makers, after manufacturing, each shaft is subjected to strict dimensional control and non-destructive testing (NDT) to ensure its complete health.

Long gear shaft manufacturing process

The manufacturing steps of this type of shafts in the new gear makers are done step by step and in compliance with international standards:

1. Choosing the right material

The first step in making a long gear shaft is to choose the right steel based on the working conditions. If the part works in high temperature or corrosive environment, heat resistant alloy steels are used.

2. Primary cutting and rough cutting

After selecting the material, the raw piece is cut to the required length and the primary turning operation is done by a heavy-duty lathe or a twin-axis CNC lathe. At this stage, most of the excess material is removed and the overall shape of the shaft is formed.

3. Heat treatment (Hardening & Tempering)

To increase the strength, the shafts are heat treated in special furnaces and then annealed (tempering) to maintain strength and toughness at the same time.

4. Precision grinding and final polishing

The next step is axis grinding to create exact tolerance and alignment. This stage is very sensitive especially in long shafts; Because even a small deviation can interfere with the performance of the part.

5. Grinding and finishing

Gears are machined on the axis with precise gearing devices depending on the type of application; Then the whole piece is smooth, aligned and ready to be installed in the industrial system.

The equipment used in the new gear makers

The workshop of Novin Garibsazan is equipped with a set of modern industrial machines designed to manufacture large and long gear shafts, including:

CNC lathe machine with cutting length of up to 5 meters
Stone axis machine with accuracy of more than hundredths of a millimeter
Precise gear cutting and stone gear machine
Dynamic balance machine
Heat treatment and induction hardening furnaces
Precise and laser measuring tools

This equipment has made it possible to produce the most diverse industrial shafts with any type of rib and central hole.

Long gear shaft applications

Long gear shafts are used in a wide range of industries. Some of the main uses are:

Power transmission system in steel rolling lines
Torque transmission axis in large industrial gearboxes
Turbine and compressor shafts
Drilling machines and mining machinery
Transmission equipment in cement and petrochemical industries
Large pumps and power coupler systems

This wide range of applications shows why the demand for long gear shaft manufacturing in Tehran is increasing and companies like Novin Garib Sazan have a large share of this market.

Features of the long length gear shaft produced in Naveen Gear Makers

The shafts that are made in the new collection of gear builders have the following premium technical specifications:

Using imported and domestic high-quality steels
High dimensional accuracy up to ±0.01 mm
Performing balance test and final quality control
Surface hardening operations to increase lifespan
High resistance to vibration and wear
Possibility of manufacturing according to customer's customized plan

All manufactured parts have technical certificates and quality test results to ensure the confidence of the country's major industries.

Factors affecting the price of long gear shaft

The final price of a long gear shaft depends on several factors, including:

Type and quality of steel used
Shaft length and diameter
Type and dimensions of teeth
Dimensional tolerance required
Need for heat treatment and precise grinding
Production volume and customer order

However, the great advantage of new gear builders is to offer fair price for high quality because this series has eliminated extra costs by producing directly and without intermediaries.

Manufacturing standards and quality control

In Navin Gear Makers, all processes are carried out according to international standards such as DIN, ISO and AGMA. All shafts undergo quality control tests after production including:

Exact dimensional test with micrometer and digital caliper
Lam-out test
Dynamic balance test
Surface hardness test
Ultrasonic or magnetic test to identify cracks

This issue has caused the products of this collection to be used in sensitive industrial projects in the country, including steel, oil and gas companies, and automobile manufacturing.

The benefits of cooperation with Navin gear manufacturers

The company Novin Garib Sazan Tehran has become a reliable option for various industries due to its expert team, precise machinery and long experience. The most important advantages of cooperation with this collection are:

Exclusive design and construction according to customer's plans and needs
Pre-construction engineering consultation
Using raw materials with valid birth certificate
Delivery on time without loss of quality
After sales service and construction warranty

These features have made Navin Garibsasan to be known not only in Tehran but also in the whole country as a symbol of quality in manufacturing industrial gear shafts.

The difference between long gear shaft and normal shaft

Normal shafts are usually used in short distances to transmit power, and their mounting accuracy is not as sensitive as long shafts. while long gear shaft:

Requires a more accurate balance
Subjects to more bending and twisting during operation
It has a more complicated turning and grinding process
Requires precise holders at both ends of the axis

For this reason, only well-equipped companies such as Novin Garb Shazan Tehran have the ability to manufacture these parts with good quality.

Maintaining and increasing the life of the long gear shaft

In order to maintain the useful life of industrial shafts, the following points should be taken into account:

Preventing operation in severe vibration conditions
Continuous lubrication of gear contact area
Precise adjustment of component alignment during installation
Using vibration absorbers in long transmission lines
Periodical monitoring of wear of teeth and contact surfaces

Novin Garib Shazazan besides production, also offers repair, reconstruction and overhaul services of gear shafts so that different industries can benefit from their parts with the lowest long-term maintenance costs.

The role of reverse engineering in the production of industrial gear shafts

In many projects, the technical drawing of the part is not available or the initial external product is obsolete. In this case, reverse engineering is the only solution. Using precision measuring devices and 3D modeling software, the New Gear Makers design team takes old samples and prepares a complete CAD model of the gear shaft. Then, according to the standard and suitable material, a new version is produced.

This feature reduces the downtime of production lines and saves the cost of repairing and replacing imported parts.
