Device and method for balancing at least partiaily a load torque

摘要

The mechanism for balancing the loading torque of an operating microscope (2) comprises a gas spring which produces a linear force. This is connected to a crank system (11-19) which is connected to an adjustable connecting system comprising a pin (10) which can be fitted into bores (9) around the periphery of a control wheel (8). An Independent claim is included for a method for adjusting the loading torque equilibrium of an operating microscope using the mechanism.
