Kinematic model: gear drive (GL 105)

Kinematic model: gear drive (GL 105)

investigation of single-stage and multistage spur gears

CodeGl105

Description:

  • The gear is the element of a machine that transmits and transforms motion.
  • A gear comprises at least one drive, an output and a frame.
  • Gear drives are uniform translation gears.
  • The rotary motion is transferred from one shaft to a second through positive transmission by gears.
  • In spur gears, the gears are mounted on parallel axles.
  • The drive and the output shaft are arranged in parallel.
  • Planetary gears are a type of spur gears, in which the drive and the output shafts are on the same axle.
  • The GL 105experimental unit can be used to study gear drives in the form of spur or planetary gears.
  • The unit focuses on the consideration of kinematics.
  • The experimental unit consists of a base plate with a fixed axle, on which is mounted a pivoting rail.
  • Two other axles can be attached at any position on this rail.
  • Selecting and combing the gears with different numbers of teeth allows you to realise different transmission ratios and gear types.
  • The rail is locked in experiments with spur gears.
  • Depending on the aim of the experiment, one or two additional axles can be positioned on the rail.
  • The gears can be coupled to each other via driving pins or to the fixed axle.
  • It is driven by hand.
  • The full revolutions are counted to determine the transmission ratio.
  • To investigate planetary gears, the rail is released and pivoted about the fixed axle.
  • The rail serves as a planetary wheel support on which the planetary wheels are positioned and represents the input of the gear.
  • The sun wheel forms the output of the gear.
  • It is driven by hand.
  • The transmission ratio can be determined by counting the full revolutions.
