Industrial gearboxes are the foundation of mechanical power transmission. They play a pivotal part in diverse industries from manufacturing, mining, and textiles to automation. In this complete guide, we will explain how gearboxes function, how to choose one, where to source it, and how OEMs can adapt gearboxes into their systems.
Whether you are an engineer, procurement manager or OEM, this guide will get you thinking differently and more effectively on your gearbox decisions.
What Is an Industrial Gearbox?
An industrial gearbox is a device that transfers power from an electric motor to a machine. It changes the torque and speed between the motor and the load to ensure the machinery rotates in a controlled and efficient manner.
Gears: Move the energy and change the torque & speed.
- Shafts: Transfer the rotary energy.
- Bearings: Support the shafts and decrease friction.
- Housing: Protects inner components and keeps lubrication in place.
Why Gearboxes Matter
They reduce the speed and increase the torque of a motor, enabling machines to perform heavy-duty operations without damage or performance loss.
Varieties of Industrial Gearboxes and their Usage
Selecting the appropriate gearbox is highly dependent on the application. Here are the types of gearboxes in occurrence:
Helical Gearbox
- Installed: Packaging, conveyors, heavy industrial machinery.
- Advantages: Quiet, highly efficient and typically rated for high loads.
Worm Gearbox
- Installed: Lifts, elevators, textile machinery.
- Advantages: High reduction ratios, compact size, low noise.
Bevel Gearbox
- Installed: Mining, steel, marine.
- Advantages: Power transfer between shafts common to intersecting shafts.
Planetary Gearbox
- Installed: Robotics, automation, aerospace.
- Advantages: High torque density makes for a compact unit.
How to Choose the Right Gearbox
Choosing the right gearbox is not only the cost; it is about performance, durability, and compatibility with the system you are designing.
Factors to Consider
- Torque Requirement – How much force is required to rotate your load?
- Speed Ratio – How much speed reduction is required?
- Mounting Location – Horizontal, vertical, or custom.
- Operating Environment – Dust, moisture, temperature, and vibration.
Service Life – How often will the gearbox be serviced? How long are you estimating for the gearbox to last?
Comprehending Gearbox Supply Chains
Thinking about throughout supply chains at this level is as important as obtaining the right gearbox for your machine or application.
Where Do Gearboxes Come From?
Most industrial gearboxes are manufactured by companies whom specialty is engineering and then sold through a distributor or OEM partner. Some companies also build gearboxes to customer specifications for certain machinery.
Evaluating a Gearbox Supplier
Review Quality Control Programs (ISO, CE)
- Evaluate Experience
- Ask About After-Sales Support
- Make Demands for Customizations When Necessary
Gearboxes For OEMs: Integration & Custom
Original Equipment Manufacturers (OEMs) need gearboxes that are reliable, scalable, low cost and fit nicely into their equipment and machines. OEMs expect their manufacturers to make sure gearboxes meet the application requirements and deliver products that are less than market standard!
What Makes OEMs Order Custom Gearboxes
- Performance specs
- Space and weight optimized
- Volume and quality consistency
Maintenance and Prevention Tips
Every gearbox in the world is going to require regular maintenance in order to operate well. Many times, larger gearboxes for large units will not have a good life expectancy if they are not regularly maintained. Preventative maintenance will extend the life of the gearbox for many years.
Maintenance Checklist
- Check lubrication levels
- Check for excessive vibration or noise
- Check for loose bolts and shaft alignment
- Replace worn seals or bearings
Common Gearbox Failure Issues
- Overheating: Caused by lack of lubrication or overload
- Excessive Noise: Usually due to gear wear or misalignment
- Oil leak: Worn or damaged seal or gasket
Regular inspection of your gearboxes can help you identify failing components before you face an unplanned and costly outage.
Latest Trends in Gearbox Technology
Intelligent Gearboxes
Modern day gearboxes are equipped with sensors that monitor in real-time, key performance indicators, like temperature, vibration, and load. This enables predictive maintenance and enables more uptime.
Energy Efficiency
New designs and material technology are paving the way for more energy efficient gearboxes with less energy loss. This will help industries decrease operational expenses and meet their environmental impact obligations.
Compact & Modular Footprints
OEMs like smaller gearboxes. Gearbox manufacturers create models that have the same power specifications as existing models but require smaller footprint envelopes perfect for robotic arms, conveying lines, and other congested machined layouts.
Gearboxes Are Used by Various Industries
- Textile: Exact speed control for looms and spindles
- Cement & Mining: Torque with heavy load
- Food & Beverage: Hygiene compliant sealed gearboxes
- Automation: High-speed compact gearboxes for robotics
- Material Handling: Conveyor systems and hoist systems
- If it moves, lifts, turns or rotates, it has a gearbox.
