2. Louden Machinery Company - Wikipedia

   en.wikipedia.org/wiki/Louden_Machinery_Company

   The company continued to expand its product line in the 1920s and 1930s, adding a wide array of products, including barn cupolas, exhaust and intake hoods and louvers, fans, valves, pulleys, power hoists, concrete mangers, a patented garage door hanger (using overhead door tracks for ease in opening and closing), playground equipment (including ...

3. Line shaft - Wikipedia

   en.wikipedia.org/wiki/Line_shaft

   The fixed pulley on the upper shaft is driven at constant speed by a belt from the power source. The loose pulley ('idler') allows the machine to be stopped in isolation – necessary for changing speed. The stepped pulleys (left) provide three drive speeds for the machine tool (not shown), depending on which pair of pulleys is connected by the ...

4. Pulley - Wikipedia

   en.wikipedia.org/wiki/Pulley

   Flat belt on a belt pulley Belt and pulley system Cone pulley driven from above by a line shaft. A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.

5. Toothed belt - Wikipedia

   en.wikipedia.org/wiki/Toothed_belt

   Supercharger drive belt in a dragster. A toothed belt, timing belt, cogged belt, cog belt, or synchronous belt is a flexible belt with teeth moulded onto its inner surface. Toothed belts are usually designed to run over matching toothed pulleys or sprockets. Toothed belts are used in a wide array of mechanical devices where high power ...

6. Block and tackle - Wikipedia

   en.wikipedia.org/wiki/Block_and_tackle

   A block and tackle [1] [2] or only tackle [3] is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.. The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load.

7. Continuously variable transmission - Wikipedia

   en.wikipedia.org/wiki/Continuously_variable...

   The V-belt needs to be very stiff in the pulley's axial direction to make only short radial movements while sliding in and out of the pulleys. The radial thickness of the belt is a compromise between the maximum gear ratio and torque. Steel-reinforced V-belts are sufficient for low-mass, low-torque applications like utility vehicles and ...
