  2. Rolling resistance - Wikipedia

    en.wikipedia.org/wiki/Rolling_resistance

    Railroads normally use roller bearings which are either cylindrical (Russia) [63] or tapered (United States). [64] The specific rolling resistance in bearings varies with both wheel loading and speed. [65] Wheel bearing rolling resistance is lowest with high axle loads and intermediate speeds of 60–80 km/h with a Crr of 0.00013 (axle load of ...

  3. Wheel - Wikipedia

    en.wikipedia.org/wiki/Wheel

    Wheel. An early wheel made of a solid piece of wood. A wheel is a rotating component (typically circular in shape) that is intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines.

  4. Bearing (mechanical) - Wikipedia

    en.wikipedia.org/wiki/Bearing_(mechanical)

    A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.

  5. Rolling-element bearing - Wikipedia

    en.wikipedia.org/wiki/Rolling-element_bearing

    A sealed deep groove ball bearing. In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, [1] is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very ...

  6. Caster - Wikipedia

    en.wikipedia.org/wiki/Caster

    A swivel caster. A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the "vehicle") to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment.

  7. Bicycle wheel - Wikipedia

    en.wikipedia.org/wiki/Bicycle_wheel

    The front wheel from a racing bicycle. Bicycle wheel with wooden rim Nipples Spokes Cross-section of a rim A Shimano Dura-Ace freehub-style hub. A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels.

  8. Mecanum wheel - Wikipedia

    en.wikipedia.org/wiki/Mecanum_wheel

    A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...

  9. Centreless wheel - Wikipedia

    en.wikipedia.org/wiki/Centreless_wheel

    Centreless wheels are toroidal in shape and have one or multiple bearings along the rim. Propulsion can be achieved in different ways, such as with gear teeth along the inner surface of the rim. They can be made lighter than solid and spoked wheels, resulting in better handling, [1] and less rotational inertia. [citation needed]
