ER Worm Gears - Radicon

Gear case is of streamlined design rugged in construction made of close-grain cast iron. It is completely oil-tight dust-proof and capable of being installed in the open without a separate cover. The faces and bores are accurately bored and machined on latest precision machines to ensure perfect alignment and interchangeability. Worm/Worm Wheel

2 The worm gear unit efficiency. Considering for discussion only the efficiency of the worm gear pair this is given by = m m w tg tg 6 where: m is the helical angle of the worm; - the friction angle in the worm gear pair. That last angle is given approximately in the form 5 3 1 1 1 / 10 0 = n tg tg 7 where n1 is the ...

Worm gears Worm wheel sets - CAVEX GmbH

geometry is far superior to standard worm gear design. The name CAVEX says it all composed from the Latin word concavus the profile on the worm and convexus the profile on the worm wheel. Thanks to worm teeth with a concave flank profile concave worm paired with convex worm wheels CAVEX worm gearboxes are far superior to comparable

Design of Pneumatic Conveying System

From David Mills ‘Pneumatic conveying system design guide’ the solid loading ratio ɸ is 0.5. Therefore ṁ = ρ × A × v = 8000 Kg/hr = 2.2 Kg/s Were ρ is the density of the mixture A is the area of cross-section of the pipe and v is the velocity of discharge. By considering the solid loading ratio ṁ becomes ɸ = ṁ powder
