CRESCENT Extruder Gearboxes having
hardened and ground gears in double reduction, parallel shafts, horizontal
models are intended to satisfy characteristic requirements and condition
commonly encountered in single screw extrusion process. The gear units are
quite capable to transmit the high torque required for pressuring and
plasticizing moulding materials and also to absorb the high axial thrust
loads through built-in spherical roller thrust bearing. The axial bearing
housing integral with the main case is standardized to accommodate suitable
thrust bearing and corresponding output shafts.
All gear teeth are made with proper profile correction as per
most modern method using computer aide techniques to improve
transmission capacity and efficiency.
These gears are heat treated in modern sealed quenched furnaces.
These are subsequently flank grounds to precision grade to ensure
high standard of accuracy, long life, quiet running characteristics,
and low noise.
H2-110 to H2-315
5:1 to 40:1
5 kw to 150 kw
All the components of gearboxes undergo a very strict quality control
check at different stages of production. Finish product are finally tested
to ensure that no scope is left for complains about noise, oil leakage,
temperature rise, etc.
NOTE - This catalogue contains
specifications, dimensions, and ratings for selection of standard extruder
gear drives against usual screw sizes/extrusion plants. However, mounting
flange and output shaft version maybe customized to suit any special
extruder and screw shaft requirements.
