Small precision couplings supplier Huco Dynatork has become the UK distributor of Delta flywheel couplings from Guardian Couplings. The Delta range is specifically designed to deliver smooth power transmission, with reduced noise and vibration, for diesel driven hydrostatic machinery including forklifts, agricultural vehicles and off-highway plant equipment.
These Delta couplings have been tried and tested in many different applications around the world and have been designed for easy installation using a single-piece design which incorporates a hardened steel hub that is pre-assembled into a glass-fibre reinforced flange. The coupling attaches to the engine flywheel, taking advantage of elastomeric grommets that provide a steady dampening effect, protecting against normal engine vibrations and shock loading.
While the couplings are suited to accurately aligned drives, they are also able to accommodate the small angular, parallel and axial misalignments which are typical to piloted flange connections. They have been designed for long-term reliability in demanding applications with the latest tier engines, and are able to transmit a nominal torque of up to 693Nm and a maximum torque of 1730 Nm. The hubs can be specified with a straight bore and keyway with set screw retention for straight pump shaft demands, or with a spline shaft connection.
The Delta range is suitable for use in almost any industrial environment, thanks to an operating temperature window ranging from -40 to 100degC. Additionally, lithium-based grease is applied to the hub at assembly to deliver an extended service interval. The couplings' performance can be further maximised when used in combination with engine housings from Guardian’s hydraulic pump mount range, which is also available from Huco in the UK.
Guardian Couplings and Huco Dynatork are both part of Altra Industrial Motion, the supplier of power transmission components.
