Global energy demand is predicted to be about 30 percent higher in 2040 compared to 2010 (1). Energy demand growth will slow as economies mature, population growth moderates and efficiency gains accelerate. This paper will focus on...

The application of cylindrical roller bearings (CRB) is widespread in mechanical engineering. CRB can carry comparatively high loads and are usable in high speed ranges. These bearings have been proven to be variably applicable and economic. With...

In the late 1970's a balancing machine salesman visited a customer's plant who had just received a new balancer from the salesman's competitor. The plant manager said they were very happy with their automatic balancing machine and...

This paper will review the significant manufacturing and processing benefits that arise from this new class of secondary-hardening steels, and analyze the potential implications and opportunities. C61 and C64 were computationally designed to take advantage of high-temperature,...

A detailed evaluation of furnace heating systems will be performed. Topics of discussion will include application guidelines for both gas fired and electrically heated furnaces. Heating system selection will consider operating temperature, processing atmosphere and heating method...

Induction hardening is widely used in both the automotive and aerospace gear industries to minimize heat treat distortion and obtain favorable compressive residual stresses for improved fatigue performance. The heating process during induction hardening has a significant...

Induction hardening of gear teeth is a well known for its challenges, but also for its potential for improved quality and process control. For complex geometric parts like gears, the power density and induction frequency need to...

The service life of a gearbox is determined by many factors. The bearings in the gearbox play a major role since they themselves deliver an important function and in addition interact with the shafts, the casing and...

Gear tooth wear and micropitting is a very difficult phenomenon to predict analytically. The failure mode of micropitting is closely correlated to the lambda ratio . Micro pitting can be the limiting design parameter for long-term durability....

Since the 1694 invention of the involute curve by the French scientist, Philippe de la Hire, and the application thereof to gearing by the prolific Swiss mathematician Leonard Euler, the world has embraced and developed this type...
