Influence of manufacturing variations of spline couplings on gear root and contact stress
Involute splines are widely used in mechanical systems to connect power transmitting gears to their supporting shafts. These splines are […]
Hob quality basics
The quality of a hob directly affects the final quality of the gear it generates. AGMA has developed a standard […]
Perfect Pitch
Gear manufacturers are turning to workholding to help reduce costs without compromising quality. Pitch Line Fixtures, for example, can be […]
Power Skiving with integrated cutter resharpening
Gear manufacturing by Power Skiving takes the traditional approach: After a cutter has reached its maximum wear, the operator changes […]
Chamfering of cylindrical gears: Innovative new cutting solutions for efficient gear production
Cylindrical gear chamfering and deburring is a rather “unloved” process that adds cost but without delivering readily apparent improvements in […]
Tooling & Workholding: Why precision clamping matters
Precision clamping devices can be custom designed for applications and can vary over a wide range of industries. David Jones, […]
Tooling & Workholding: Improving tool holder performance
The four critical requirements for tool holders are clamping force, concentricity, rigidity, and balance for high-spindle speeds. When these factors […]
Long hob cost savings over the length of a job
Manufacturers consider many factors when shopping for a gear hob solution: What material is being cut? What is the pitch […]
Conjugate Action Law in Intersected-Axes Gear Pairs and in Crossed-Axes Gear Pairs
The article deals with the kinematics and the geometry of geometrically-accurate gearing (with perfect gearing). Considered at the beginning for […]
Gearwheel manufacturing in a 34-second cycle
Minimizing production times to ensure competitiveness is one of the most important challenges in the automotive industry — Henry Ford […]
Micro-skiving – (r)evolution of a known production process
Production of internally toothed gear wheels is possible in many different ways. Different techniques such as gashing, broaching, wire EDM, […]
Chamfer Hobbing Tools Up
In the last few years, chamfering and deburring have gained new respect and risen to a level of importance equal […]
Advantages of flat broaching machines
A broaching machine requires precision broaching tools to increase productivity and efficiency. New broaching tools can be expensive and difficult […]
Reducing Tool Wear in Spiral Bevel Gear Machining with the Finite Element Method
Due to the complexity of spiral bevel gear machining, the cutting tools can be a significant cost of gear manufacturing. […]
Filling Some Gaps in Spline Design Guidelines: Centering, Friction, and Misalignment
Editor’s note: At the author’s request, some statements have been removed for clarity since the article was originally published in October, […]
Methods to Determine Form Diameter on Hobbed External Involute Gears
In custom designs of external spur or helical gears, designers generally prefer a lower form diameter for greater transverse contact […]
Taking deburring to the next level
Once a gear is created, deburring becomes a necessary step to ensure a gear’s accuracy. Traditionally, deburring has been done […]
Tooling & Workholding: Making Out-of-Round Parts Round
One of the most vexing problems in machining today is how to most efficiently make an out-of-round part round. In […]
