Description:

PG TYPE ◢
End discs and hubs welded by open slot is
full permeability process as well as being treated by pressure removal anneling,
and the hubs and shaft about hot jacket stress fit process that can help
transmit a quite large torque which is applicable to all types of conveyers.
PH TYPE ◢
End
discs and hubs are made integral forming by high-quality cast steel or thick
steel and are treated the process of homogenization that would bring no defects
from welding process with its connection point has a large and a smooth R andgle
that can alleviate the concentration of press. Permissible transmittable torque
and moment of flexion are bigger then PG type.
PT TYPE ◢
End discs and hubs are made integral
forming by high-quality cast steel but is different from other of PH mode on its
shape. Outer circumference of end discs not welded directly on shell but is
being processed of the butt weld with the hubs so as to make soldering track
avoiding from the high stress part which is a quite advanced belt pulley that is
the most appropriate for large high-loaded conveyer and small diameter belt
pulley.
PHK/PTK TYPE ◢
Having the same structure as that of
PH/PT types but being connected of the hubs and shaft by adopting the key-less
connectors rather than hot jacket stress fit that is not only a convenience for
assembly and maintenance but also a more even and firmer connection of the shaft
and hubs than that of hot jacket stress, thus this type can bear a greater
fluctuation stress.
