In therapy today the most modern training equipment is used to aid rehabilitation after a long illness or for the prevention or cure of joint pains. To date the physical load in training has been determined by the weights used. In the newest generation of equipment the weights have been replaced by an adjustable hydraulic resistance. State-of-the-art technology can also assess the progress made in training and adjust the load individually for each patient.
Ketterer has developed a combined worm gear pair/planetary gear set for the adjustment of the hydraulic resistance. The special characteristics of both gears allow the hydraulic resistance to be adjusted precisely.
With this drive unit we can offer you an optimal solution which combines precision and function. The small, space-saving units can be integrated into spaces requiring compact, low-noise and high-performance drives.
