Gear coupling

Gear coupling

The gear coupling GD is composed of two hubs in steel UNI EN ISO 683-1:2018 fully turned, externally toothed with rounded profile and assembled only with a sleeve in polyamide stabilized resin, toothed internally. 

Due to the tooth profi le with which the hubs and the sleeve are connected, you can obtain a high contact surface also in presence of misalignments, in order to reduce the contact pressures and promote a longer life. 

The connection polyamide/steel assures silent and reliable functioning, in absence of maintenance and lubrication. This kind of coupling represents a reliable and economic kind of connection, for medium and big power industrial purposes.

Description of the sleeve

The standard sleeve is made in polyamide 6.6 stabilized resin and its properties are as follows:

  • Resistant to all common lubricants and hydraulic fluids 
  • Suitable to operate in a conti nuous way on temperatures from -25°C up to 90°C and for short periods up to 125°C 
  • Optimum sliding properties 
  • High insulating capacities 
  • Optimum mechanical properties
