Cycloidal Speed Reducers
ABSTRACT
In accordance with modern development trends at complex industrial systems, High Power Density (HPD) speed reducers with high gear ratio (GR) and good efficiency are becoming a necessity. The most famous representatives of HPD speed reducers are planetary, cycloidal and harmonic solutions. The cycloidal reducers belongs to a group of new generation planetary gears. They are broadly used in the modern industry (robot industry, satellite technology, CNC machines, process industry, medical equipment, electric vehicle, renewable energy systems, human robot collaboration, etc). One of the most important application of cycloidal speed reducers is in the field of robotics because the each robot joint has one HPD reducers and these reducers participate with 25% in the total cost of industrial robot. For these reasons, the investigation in cycloidal speed reducer area is very important for modern industrial trends.
