Gear Couplings
Gear couplings have been used in many industries due to their reliability and consistent performance. They contain rigid and flexible components. The flanges are rigid and inner hubs are flexible. The flanges have internal gear teeth and the hubs have external gear teeth. The flexible hubs can be bored up to 650mm.
There are various models of gear couplings such as floating shafts coupling, large gear coupling and spacer shafts coupling. We at Trans-Tech stock a comprehensive range of G20 series gear couplings which is equivalent to the design and quality of Rexnord and Falk.
Engineers may also be interested in spacer gear couplings for long distances between shaft ends. More information can be found on the below link:

Gear Couplings
  • Gear couplings have a small size yet provide high torque capacity. The design minimizes loss of power transmission.
  • The hubs teeth are crowned over a large surface area which lowers stress under misaligned scenarios.
  • Gear couplings permit the following misalignments:
  • Parallel Misalignment: The driving and driven shafts are not parallel to each other, but not in the same straight line
  • Angular misalignment: The driving and driven shafts installed with a limited angle
  • End floating: The driving and the driven shafts slide slightly along with the gear teeth
  • Composite misalignment: In most of the cases, above three alignment appear in mixed form

APE Rubber Couplings
  • Heavy load, but compact design coupling
  • High speed up to 500rpm
  • Low speed but high starting torque
  • End floating application
  • Spacer required, due to longer distance between shaft ends
  • Low load and light weight application is not recommended
