Grid Type(UGF)
1Pages

FEATURES Has few components such as hubs, Grid, Cover, Seal & Fasteners. •HUBS are made from high fatigue strength steel, so that tooth fatigue failures are eliminated. Hubs are accurately machined to permit utilization of any hub surface for measurement of shaft alignment. •GRID is made from high strength spring steel and duly heat treated to get high hardness, so that the stresses developed in the grid by transmitted load are well below the design value. Both straight & taper grids are available. • COVERS are made of Graded Cast Iron / Aluminium covers which permit higher running speeds. SEAL is made of synthetic material to withstand oil and dusty atmosphere. •FASTENERS are made of high tensile grade materials. •SIMPLE / EASY MAINTENANCE As there are fewer & less complicated components, maintenance is less & when regular inspection / lubrication is done the coupling gives good life. • LOW OPERATIONAL COST The spare required is mainly the grid, which is a low cost component and that also gives substantial life. Hence the operational cost is much low. •SMOOTH & QUIET OPERATION The coupling components except grid to hub have no relative movement. Hence are smooth in operation. In grid & hub also the relative movement is very low & depends on misalignment. Hence the coupling as a whole is smooth & quiet in operation. •LUBRICATION Utkarsh special grease is developed to resist separation of base oil & thickener due to centrifugal forces encountered in Grid coupling to avoid wear & tear.
