Have an existing gear but no drawing? This practical guide explains how to identify and measure a gear using the Number of Teeth, Outside Diameter, Module, Pitch Diameter, Pressure Angle, and other key parameters, what can be measured with a caliper – and when professional Reverse Engineering is required.
Understanding gear module is essential for selecting the right gear. This guide explains what gear module is, how it affects tooth size, torque capacity, gear strength, and compatibility, how to estimate it from an existing gear, and why choosing the correct module is a critical engineering decision rather than a simple catalog selection.
Learn how to calculate gear ratio, understand its effect on speed, torque, and power, select the right gears for your application, and avoid common design mistakes. This guide also covers gear materials, case-hardened gears, practical selection tips, and essential gear terminology.
Most drivetrain problems are not caused by a single faulty component, but by the interaction between gears, gearboxes, couplings, shafts and bearings. Learn how system-level thinking leads to better motion control, higher accuracy and more reliable mechanical designs.
Most gearbox failures are not caused by poor manufacturing or incorrect gear ratios. They are caused by uncalculated radial loads, shock loads, peak torque, misalignment, and other real-world operating conditions. Learn why replacing the gearbox often doesn’t solve the problem – and how to select a gearbox based on engineering reality rather than catalog specifications.
Most engineers begin designing a worm gear transmission by selecting the required gear ratio. However, two worm gear sets with the same gear ratio can behave very differently depending on the number of worm starts. This article explains how the number of starts influences efficiency, lead angle, friction, back driving, self-locking, and overall transmission performance, helping engineers choose the right Worm & Wheel configuration for their application.
Most engineers think of bevel gears as a simple way to transfer motion at 90°. In reality, bevel gears represent an entire family of solutions including miter gears, angular bevel gears, hypoid gears, precision motion systems, and high-torque drive technologies. This article explores ten applications that many designers overlook and explains how the right bevel gear selection can simplify mechanical systems, improve efficiency, reduce noise, and eliminate unnecessary components.
Most engineers focus on enclosure gaskets when designing for IP67 or IP68 protection, yet every screw passing through the enclosure wall can become a potential leak path. This article explains why sealing fasteners matter, explores the real role of Black Oxide finishes, and examines how Seelskrew® fasteners help eliminate one of the most overlooked weaknesses in sealed enclosure design.
Most medical device engineers start by asking how accurate a motion system is. The more experienced ones ask a different question: how accurate will it still be after millions of motion cycles? That shift in thinking helps explain why Rack & Pinion remains a serious contender in some of the world’s most advanced medical systems.
Gear performance is not determined only by geometry – but by metallurgy and heat treatment philosophy.
In this technical guide, we explain the real difference between EN8 (080M40), EN36 (655M13) and EN24 (817M40), and why serious gear manufacturers prefer Case Hardened EN36 for heavy-duty applications.
We compare Case Hardening vs Induction Hardening, analyze torque capability improvements, and explain how surface hardness directly affects wear, fatigue life, backlash stability and long-term gearbox reliability.
Including a real Module 2 gear case study showing how torque capacity increased from 70 Nm to 195 Nm after Case Hardening.
