Highly Reliable Pipe Extrusion Facilities
The OMNIA pipe extruder features a low level of complexity leading to a high rate of reliability.
The proven torque master gearbox incorporated into the OMNIA extruder’s transfer case requires only four shafts (instead of seven) to operate. This reduction in complexity is accompanied by a higher percentage of performance. This, in turn, enhances operating reliability.
Excluding rubbing-caused disturbances
The use of a central gear wheel to link the drive shafts to the screws moderates the latter’s radial movement. This, in turn, minimizes any alterations of the screws’ flank clearance, thus precluding any rubbing-caused disturbance of operation.
The gears – offering long service lives and high reliability
The gearbox is equipped with a combined splash and forced-feed circulating lubrication system. This gearbox-lubrication aggregate is integrated into the gearbox. Two lubricants are fed into two separate oil circulation systems. One of these has the greater viscosity required by slowly-operating transfer cases in order to avoid pitting. The other lubricant has the low viscosity needed in the quickly-operating undercarriage to minimize splashing and thus loss of energy. Helical gearing placed on the drive step increases the service lives of the bearing by 1.4 to 1.8 times. This increase is accompanied by one of the intervals between maintenance operations on the gearbox’s components.
