MECHANISM GENERATING MECHANICAL WORK BY ECCENTRIC BALANCE WITH ADJUSTABLE PITCH CALCULATED BY MATHEMATICAL INDUCTION

摘要

The invention relates to a mechanism generating mechanical work by eccentric balance with adjustable pitch as a bearing element for cranes or suspended roofs. According to the invention, the mechanism consists in adding a short rod (AO) under the normal rod of the balance (AH), which rests on a balance support at one end (O) and, at the other end, will be enclosed with the initial long rod of the balance (A), thus creating an eccentric balance whose long rod will have an imaginary support at the half (O') of its length for the equal weights at the ends of the long rod (AH), said long rod of the eccentric balance being sectioned into two parts, on the length, opening said two new formed rods (AB and AC) by an angle ( α ), where the eccentric balance is in mechanical balance (AO'H), they remaining enclosed in the short rod, at one of their ends (A) but through an axle which enables the rotation in the horizontal plane, the weight at the free ends of the long rods being equally divided to the free ends thereof, trying to maintain the weights acting in the balance at an equal level, namely, at the opposed ends of the mechanism (A=B+C), thus creating the eccentric balance with adjustable pitch, where the long rods describe a mirrored rotation in the horizontal plane while they can synchronously get closer and apart from one another under an angle ( α ) and when the ends of the weight-carrying long rods (B and C) are driven to get closer to the central axis of the mechanism (B' and C'), the long rods will create by their rotation an additional distance (HH') to the height (AH) of the triangle (ABC) in relation to the imaginary support of the balance (O'), extending the arm (O'H') of the force with a mathematically computable additional length and the balance creates a momentum of the ascending resistance force at the opposite end (A) in relation to the free ends of the long rods.
