TOMASI FRATELLI DI TOMASI UGO E NATALINO ( S.N.C. )

The rotation of high speed shaft should not be more than 1500 rpm; The circumferential velocity of gear tranmission should not be more than 20 m/sec; The temperature of work environment should be -40-45°C. If it below 0°C, before start, the lubricating oil should be pre-heated to above 0°C. This speed reducer can be run at clockwise and counterclockwise direction.

These series which are provided in foot- (PA) and flange (PF) mounted options serve up in drive systems that need wide reduction ratio and maximum 26900 Nm of output moment.

Helical bevel gear units with 90° input and output axis range. Casing with feet, flange F options. A rigid structure in case. System resistance calculations are made in accordance with ISO, DIN and NIEMANN standards. Different input options may be provided (Coupled motor, IEC, PAM, W, Servo motor connected, ...). Different output options available (Solid shaft, Hollow shaft, With shrink disc, ...).

Preferred in various transfer systems thanks to their wide reduction ratio, compact structure and easy maintenance, PGR Drive Technologies Pt/A Series gear units can be driven with belt-pulley or chain mechanisms.
