Hydraulic
couplings are used to mount the engine to pump. In a hydraulic coupling,
a pair of forces of equal magnitude are exerted in parallel but opposite
directions and cause rotation. The working technology of the hydraulic
couplings ensures a long working life with lower operating cost and long
lasting leak-tightness.
They may have features of with synthetic rubber inserts between the
coupling halves. The high performance hydraulic couplings are handy and
posses high tolerance to temperature. The reliable and robust
construction of the couplings offer greater efficiency and make them
easy to use.
Flexible Drive Coupling
Technical Data
Drive coupling consists of two steel gear hubs engaging in a sleeve of
high grade plastic material. This material has superior strength and
wide operating temperature range. The gears have crowned tooth from
which, permits axial and angular misalignment. The couplings have
undergone extensive testing under severe load conditions. They are easy
to assemble & require no maintenance or lubrication and no
transmission noise.
Assembly Procedure
The couplings have a maximum permissible angular misalignment 1.5
degrees. It should be ensured that the coupling hubs fit easily on the
shaft. No undue force should be used. Gap should be maintained between
hubs and grub screws to locate gear hubs on their respective shafts,
should be used. For shock load applications, the following formula
should be used:
