Polymer gears find increasing applications in the automotive industry, office machines, food machinery, and home appliances. The main reason for this success is their low cost. Their low weight, quietness of operation, and meshing without lubricant are also interesting. However, they have poor heat resistance and are limited to rotational transmission. In order to improve the gears' behavior, glass fiber is added

Plastic gears still have an entire frontier to explore, and how they measure up against their steel cousins is a question still being investigated.

In the last semester of my senior year of mechanical engineering, I recall having a discussion with my study group friends about the purpose of our...

We have devoted this year to going over fundamentals of gear and gearbox design and manufacture. Before we move on to other topics, I would like to...

Deadlines and budgets do not always allow for “first class” gearbox rebuilds. The challenge for rebuild shops is to find the fastest and most econo...

Lyon, France. Mechanical transmission components such as gears, rolling element bearings, CVTs, belts, chains, etc. are present in every industrial...

Despite the development and availability of a number of newly engineered, rugged materials intended for plastic gear applications, some engineers/designers continue to believe metal is better.

The most obvious difference between a spur gear and a helical gear is the presence of that “helix” angle. Civilians will call them “straight-cut” a...
