Large Gearwheels  Manufacturers, Traders, Suppliers

As one of the leading manufacturers and further processors, ISO-TECH has been producing high-quality thermoplastic products for domestic and foreign customers for more than 30 years. A broad range of production possibilities, a sustainable corporate policy and a distinct customer orientation characterize our company.
After founding the company in 1990 with initially four employees, we quickly established ourselves as a specialist in the technical plastics segment. With the help of a continuous organic growth, we have steadily expanded both the production of semi-finished goods and the range of finished parts. The first milestones were already achieved in 1995, when we were initially certified according to ISO 9001 and the staff had grown to more than 20 employees. With the opening of a second plant in 2010, we were able to expand our range of products by additional high-performance plastics. With the 25th anniversary in 2015, our owner-managed company was delivering goods into almost all branches of industry. Today, ISO-TECH employs roundabout 200 people and invests continuously in the expansion of the production range and vertical integration.
Our range of products varies from our own production of semi-finished goods to variously processed finished parts made of standard and engineering plastics or high-performance plastics. In the semi-finished goods segment, we produce plastic sheets in various standard dimensions and thicknesses However, a large part of our semi-finished goods is being processed inside our plants into individual machined parts. In addition to large as well as prototype-series, we offer our clients individually customized products. Both high and ultra-high-molecular-weight polyethylenes (e.g. PE500, PE1000) as well as polyamides (PA), polyoxymethylenes (POM) and other materials like PVDF or PEEK are being machined in our factories. A distinctive quality management, constant education and training of our employees as well as a precise selection of raw materials ensure the reliability of our products.
Sustainability is important for us at all levels – both in economic and social terms as well as in ecologic terms. In addition to a long-term policy of balanced growth, our focus is on enduring customer relationships. By running a corporate health management programme, we focus on securing the health of our employees. Furthermore, we are making an important environmental contribution by recycling 100% of our polyethylene material waste and by constantly investing in energy efficiency measures and renewable energies.

Large Gearwheels – Description
Large gearwheels are robust, heavy-duty components engineered for high-torque power transmission in demanding industrial applications. They are characterized by their substantial size, mass, and the ability to handle immense loads, making them essential for heavy machinery and large-scale power systems.
Key Features:

• High Load Capacity:
  Large gearwheels are designed to withstand very high torque and mechanical loads. Their massive size and robust construction ensure reliable power transmission even under extreme conditions.
• Robust Construction:
  Manufactured from high-strength materials like forged alloy steel or cast iron, these gearwheels exhibit excellent durability and resistance to wear. Advanced heat treatment processes (e.g., carburizing, induction hardening) further enhance their surface hardness and fatigue life.
• Precision Machining:
  Despite their size, large gearwheels are machined to tight tolerances. This precision ensures smooth meshing, reduced backlash, and efficient power transfer in high-load systems.
• Heat Dissipation:
  Their design often includes features that facilitate heat dissipation, ensuring that operational temperatures remain within safe limits even during continuous high-load operation.
• Customizable Designs:
  Depending on the application, large gearwheels can be customized in terms of diameter, number of teeth, and tooth profile. This flexibility allows engineers to design gear systems that meet specific performance criteria.

Materials & Manufacturing:

• Materials:
  Typically made from high-grade alloy steels, cast iron, or other specialized metals. The choice of material depends on factors such as load requirements, operating environment, and cost considerations.
• Manufacturing Processes:
  Often produced via casting or forging followed by precision machining. Heat treatment processes are applied to improve wear resistance and overall strength.

Applications:

• Heavy Machinery & Mining Equipment:
  Used in excavators, crushers, and conveyor systems where robust power transmission is crucial.
• Industrial Gearboxes:
  Integral in large-scale gearboxes that drive pumps, compressors, and other heavy-duty equipment in sectors like oil & gas, cement production, and steel processing.
• Power Generation:
  Found in wind turbines, hydroelectric plants, and other renewable energy systems, where they help convert mechanical energy to electrical energy.
• Marine & Railway Applications:
  Employed in propulsion systems and heavy-duty drive mechanisms that require high durability and reliable performance under continuous operation.

Conclusion:
Large gearwheels are indispensable in applications where extreme durability and high load capacity are required. Their robust construction, combined with precise machining and effective heat treatment, ensures that they can deliver reliable performance in the harshest industrial environments. Whether in heavy machinery, power generation, or marine propulsion, these gearwheels play a vital role in ensuring efficient and long-lasting power transmission.

Technical Data for Large Gearwheels1. Material & Manufacturing

• Materials:

• Typically made from high-grade alloy steels (e.g., AISI 4140, 42CrMo4) or cast iron, chosen for their high strength and durability.
• For extreme applications, large gearwheels may be produced from forged materials to improve toughness and fatigue resistance.

Manufacturing Processes:

• Casting or Forging: Large gearwheels are often produced by casting or forging to achieve the required mass and structural integrity.
• Precision Machining: Subsequent CNC machining is used to generate accurate tooth profiles and surface finishes.
• Heat Treatment: Processes such as carburizing, induction hardening, or nitriding are applied to enhance surface hardness and wear resistance.

2. Dimensional Specifications & Geometry

• Size:

• Large gearwheels typically have diameters ranging from several hundred millimeters up to multiple meters, depending on the application.

Module & Pitch:

• The gear module (m) defines the size of the teeth; large gearwheels often use higher modules to accommodate heavier loads.
