Definitions

  • This utility model relates to a crank with a plate containing holes for planetary axles and a square hole for square taper spindle.
  • crank comprised of a crank arm and a plate in which axles are mounted.
  • the plate contains trapezoidal apertures in order to reduce weight.
  • the plate is a separate element, mounted at the base of the crank arm.
  • crank arm There is known from application US 4S54191 a crank whose plate is also mounted at the base of the crank arm.
  • patent application no. US 8342553 a crank that has an ISIS-type bottom bracket spindle that is rigidly mounted in the plate.
  • the purpose of developing the utility model is to obtain a crank that can be used for bicycles equipped with the currently most popular type of square taper spindle standard.
  • the purpose of developing the utility model is also to obtain a crank in which there are firmly mounted planetary axies which are used by the gears being a part of the mechanism of the planetary gearbox.
  • This utility model relates to a crank comprising a crank arm and a piate which is characterised in that the crank arm and plate are made of one piece of material and the plate contains a hole for a square taper spindle and holes for planetary axles.
  • crank contains holes for planetary axles in a number of 3, 4, 5 or 6.
  • crank contains holes for planetary axles that are threaded.
  • crank contains holes for planetary axles that are not threaded.
  • crank contains holes for planetary axles whose centres are at a radial distance of 37.5 mm from the centre of the plate.
  • crank contains threaded holes for type I bearing rods.
  • crank contains holes for type I bearing rods whose centres are at a radial distance of 35.5 mm from the centre of the plate.
  • crank contains holes for type II bearing rods.
  • crank contains holes for type 11 bearing rods whose centres are at a radial distance of 45.5 mm from the centre of the plate.
  • crank contains supports.
