Tooth contact analysis (TCA) is an important tool directed to the determination of contact patterns, contact paths, and transmission errors in gear drives. In this work, a new general approach that is applicable to any kind of gear geometry is proposed.
rotary-type blowers? Examples: for motor KW; RPM; temperature; pressure production; lifetime; etc.
In other words, how do I choose between belts or couplings?
Over the past few decades, energy efficiency in motors has become an ever-increasing concern for OEMs and
manufacturers alike. With multiple
energy bills mandating higher efficiency across ever-broader spectrums of motors, including the most recent Small Motor Rule by the Department of Energy, efficiency has become an essential consideration when choosing a new motor.
One of the key challenges in the mining
industry today is maintaining throughput
in the face of ore grade quality that
has declined by 40 percent in the last
decade.
The improvement of the energy efficiency of industrial gear motors and gearboxes is a
common problem for many gear unit manufacturers and end-users. As is typical of other
mechanical components, the radial lip seals used in such units generate friction and heat,
thus contributing to energy losses of mechanical systems. There exist today simulation
tools that are already helping improve the efficiency of mechanical systems — but accurate models for seal frictional losses need to be developed. In this paper SKF presents an engineering model for radial lip seal friction based on a physical approach.
This paper presents a physically grounded calculation method to determine the
efficiency of worm gear drives. This computation is based on the Institute of Machine
Elements, Gears, and Transmissions (MEGT) tribological simulation, which can determine the local tooth friction coefficients (Ref. 1). With this knowledge other power losses such
as the bearings, oil churnings and seals power losses can also be calculated.
