Abstract: The invention relates to a centrifugal compressor or supercharger with an internal drive mechanism (30), which operates with great efficiency, higher speed and low noise. The compressor needs no lubrication and has a concentric input-and impeller shaft (13) for compactness. The compressor has two sets of belt drives (36) connected to a large sprocket (33).
Abstract: When, according to the invention, a multistage planetary gear is constructed with a clutch/brake device (8, 21, 22) and these devices are constructed as remote-controlled or automatically operating clutches/brakes, it is possible to construct multistage gears which are compact, and which are reliable in operation. The gear stages are configured as cooperating tooth engagements (6, 6.1, 6.2) on rotating parts, which ensures the function at high speeds of rotation and allows transfers of great power.
Abstract: When, according to the invention, a one-stage planetary gear is constructed with radially resilient planet wheels and sun shaft (1), and where the centre axes are parallel with the sun axis and positioned closer to it than the axes of the planet wheels (2), a good engagement between the contact-bearing surfaces and thereby a high degree of moment transfer are achieved. It is more-over ensured that the gear can operate at en extremely high number of revolutions.
