Bevel gears are essential power transmission components used to transmit rotary motion and torque between intersecting shafts. They provide a compact, durable, and efficient solution, particularly in mechanical systems where the direction of motion needs to be changed.

At Erdişli Makina, we manufacture bevel gears for various machinery and industrial applications based on technical drawings, existing samples, and the operating conditions of each project.

In addition to new machinery projects, we manufacture bevel gears in various sizes, tooth configurations, and materials for maintenance, overhaul, and spare-part requirements.

What Is a Bevel Gear?

A bevel gear is a type of gear with teeth formed on a conical surface, typically used to transmit power between two intersecting shafts.

In the most common applications, the shafts are positioned at a 90-degree angle to each other. However, depending on the system design, bevel gear pairs can also be manufactured for different shaft angles.

Bevel gears make it possible to change the direction of rotary motion from one shaft and transmit it to another. For this reason, they are widely used in mechanical applications ranging from machinery manufacturing to industrial gearbox systems.

Erdişli Bevel Gear Manufacturing

In bevel gear manufacturing, accurate tooth geometry and proper compatibility between the mating gears are essential.

Parameters such as module, number of teeth, shaft angle, gear ratio, tooth geometry, hub design, material, and operating conditions directly affect the performance of the manufactured component.

At Erdişli Makina, we provide bevel gear manufacturing solutions for the requirements of various machinery and industrial equipment.

Bevel Gear Pairs

Bevel gears generally operate as a matched pair. The smaller gear in the system is commonly referred to as the pinion, while the larger gear is referred to as the crown gear.

Correct matching of the tooth geometry between these two components is essential for smooth operation, efficient power transmission, and long service life.

For this reason, bevel gear manufacturing requires consideration not only of the dimensions of an individual gear but also of the specifications of its mating gear and the overall operating conditions of the system.

Manufacturing from Technical Drawings or Samples

We can manufacture bevel gears according to technical drawings as well as from existing gear samples.

In machinery that has been in operation for many years, technical drawings may no longer be available or original replacement parts may have been discontinued.

In such cases, the existing bevel gear or gear pair can be examined to determine the necessary dimensions and technical specifications for manufacturing a replacement.

Our sample-based manufacturing service provides an effective solution for:

• Recommissioning older machinery

• Replacing damaged gears

• Spare parts for imported machinery

• Equipment with discontinued or unavailable manufacturers

• Maintenance and overhaul operations

• Custom-built machinery

Materials

Material selection for bevel gears should be determined according to transmitted power and torque, rotational speed, impact loads, operating duration, and environmental conditions.

Depending on the project and application, bevel gears can be manufactured from:

• 4140

• 8620

• 1040

• 17CrNiMo6

• Bronze

• Cast Polyamide

• Aluminum

Other materials suitable for the technical requirements of the application can also be evaluated.

For bevel gears operating under heavy loads in particular, the correct combination of material and heat treatment plays an important role in ensuring a long service life.

Heat Treatment Options

Depending on operating conditions, bevel gear teeth may be exposed to significant wear and contact stresses. Where required by the application, appropriate heat treatment processes can therefore be applied.

Depending on the material and operating conditions, processes such as carburizing, induction hardening, and nitriding can be considered.

Appropriate heat treatment is intended to increase tooth surface hardness and wear resistance, helping the gear operate reliably over a longer service life.

Advantages of Bevel Gears

One of the key characteristics of bevel gears is their ability to transmit mechanical power between shafts positioned in different directions.

Key advantages include:

• Ability to change the direction of motion

• Power transmission between intersecting shafts

• Suitability for high-torque transmission

• Compact mechanical design

• Ability to achieve different gear ratios

• Manufacturing flexibility in different sizes and tooth configurations

• Durable and long-lasting construction

• Various material options

• Suitability for a wide range of industrial applications

• Adaptability to custom machinery designs

Applications of Bevel Gears

Bevel gears are used in a wide variety of machinery and mechanical systems where the direction of motion needs to be changed or power must be transmitted between shafts positioned at different angles.

Typical applications include:

• Industrial gearboxes

• Machinery manufacturing

• Agricultural machinery

• Production machinery

• Conveyor systems

• Packaging machinery

• Textile machinery

• Metalworking machinery

• Automation systems

• Transmission mechanisms

• Heavy industrial machinery

• Custom machinery and equipment

Where Are Bevel Gears Used?

When rotary motion in a machine needs to be transmitted in a different direction rather than continuing along the same axis, bevel gears provide an effective mechanical solution.

For example, in systems where rotary motion from a horizontal shaft needs to be transferred to a vertical shaft, an appropriate bevel gear pair can be used to change the direction of motion.

By selecting different numbers of teeth for the mating gears, it is possible not only to change the direction of motion but also to adjust rotational speed and torque ratios according to application requirements.

What Should Be Considered When Selecting a Bevel Gear?

Matching the external dimensions of a bevel gear to the existing system is not sufficient on its own. For reliable power transmission, both gear geometry and operating conditions must be evaluated together.

Important parameters in bevel gear selection include:

• Module

• Number of teeth

• Shaft angle

• Gear ratio

• Rotational speed

• Transmitted torque

• Face width

• Material

• Heat treatment

• Shaft and hub connection

• Lubrication conditions

• Operating duration

Correctly determining these parameters contributes to more efficient operation and a longer service life for the gear pair.

Custom Bevel Gear Manufacturing

In addition to standard applications, we provide custom bevel gear manufacturing for different machinery and mechanical systems.

Specifications such as the number of teeth, module, diameter, hub design, shaft bore, keyway, material, and other technical characteristics can be determined according to project requirements.

For gears that are not mass-produced or cannot be sourced as standard components, we provide custom manufacturing solutions based on technical drawings or existing samples.

Bevel Gear Manufacturing for Maintenance and Overhaul

After prolonged use in industrial machinery, bevel gears may experience wear, tooth breakage, or damage to tooth surfaces.

When standard replacement parts are no longer available, a new gear can be manufactured using the existing component as a sample.

This can make it possible to replace the required mechanical component rather than replacing the entire machine or mechanism.
