Pin gear attachment chain

Product photo
  • This chain is for a pinion gear drive.
  • Uses an attachment chain and special sprocket instead of a rack and pinion gear.
  • Wrap the chain around the inner/outer circumference of a drum and bolt the attachments to install, or install linearly.
  • *Use a heat treated bolt for attachment.
  • *Requires a special sprocket.

Chain Pin Gears

  • ・Uses a chain and gear for drive by transmitting power from the drive source (motor) to the reducer for linear drive or rotational drive over large radii.

    Chains require a lot of space, and gears need precision machining, which can lead to high costs and other issues. Pin Gears are perfect in these situations.

    An attachment chain is wound around the outside of a drum in place of a gear drive wheel, and a specially machined sprocket is used for the pinion gear.

    For linear drive, an attachment chain is installed linearly instead of a rack.

When selecting sprocket specifications

It is necessary to select a sprocket specification that corresponds to the customer's operating environment and the chain specification used.

Dedicated sprockets with a special tooth profile are required for attachment chain for Pin Gear, because the chain engagement differs from that of ordinary transmission.
