Kumeras technology Director, Vesa Laine presented a full-scale loaded test of a prototype drive unit, KUMERA Active Drive™.
- In this drive the counter gear is mounted to shaft with eccentric bushings. It results in 0, 50 mm sinusoidal misalignment along face width. Tests run torque reach 80 kNm and power of 130 kW. Prototypes drive nominal torque is 160 kNm. This overhead assembled counter gear leads to significant load-dependent misalignment of up to 2 mm under full load, said Vesa Laine.
He referred to several benefits of the Active Drive™ system, which are the decreased face load factor, firth gear face width that can be decreased up to 30% or power rating that can be increased up to 50 percent. Pinion face width can also be decreased. In a conventional drive the nominal power800 kW compared with 1200 kW in KUMERA Active Drive™ (with same face width).
- Kumera offers powerful drives for paper, board and tissue making lines. All components in a drive package are integrated into an effective functioning construction, underlined company´s work shop manager at assembly department, Petteri Koskimäki.
He mentioned also company´s KUMERA Backlash Adjustment System, which is user-friendly axle distance modification without dismounting the drive unit, for example for pulp lines.
