Patent KR-20180058674-A (KR)
Inventor: SHIN TAE SOO
IPC: F16H35/00
Filed: 2018-04-28
Abstract: The present invention provides a method for amplifying torque of a prime mover without increasing input of the prime mover such as a motor or a diesel engine at the same number of revolutions using the principle of the Roberval balance, resulting in the prime mover operated with output amplified several times. Figure 1 illustrates the principle of the Roberval Balance, invented by Robert de Valle in 1669. In the case of an ordinary lever, weight balance is achieved when two weights are separately placed on right and left sides at the same distance from a fulcrum, wherein a support pillar (15) functions as the fulcrum of the ordinary lever. However, in the case of the Roberval balance, weight balance can be achieved when the same weight (18) is placed on one of a left level (11) or a right level (16). In other words, even if the weight (18) positions from the support columns are different, weight balance can be achieved. An output is: P = number of revolutions * torque = ω * τ [w].
