The invention relates to an arrangement for converting reciprocating motion into even rotational motion. The arrangement comprises a frame (1), a flywheel (2), a pull member (3) attached to the flywheel by means of a free gear mechanism (4), and a brake band arranged to resist the rotational motion
The invention relates to an arrangement for converting reciprocating motion into even rotational motion. The arrangement comprises a frame (1), a flywheel (2), a pull member (3) attached to the flywheel by means of a free gear mechanism (4), and a brake band arranged to resist the rotational motion of the flywheel (2). In order to achieve smooth operation without jerks, the arrangement comprises a relief member (7) connected to the frame by means of a lever mechanism (4). When the pull member (3) is pulled (A), it presses the relief member (7) and turns the lever mechanism so that the brake band is tightened against the flywheel. When the free gear mechanism (4) draws the pull member in direction (B), the lever mechanism (9) is arranged to turn so that it reduces the tightening force exerted by the brake band on the peripheral face of the flywheel. (FIG. 1).

An arrangement for converting reciprocating motion into even rotational motion, comprising a frame (1, 31) and a flywheel (2, 32) placed thereon, a pull member (3, 33) being attached to the flywheel by means of a free gear mechanism (4, 34) so as to move in a reciprocating manner and a braking band
An arrangement for converting reciprocating motion into even rotational motion, comprising a frame (1, 31) and a flywheel (2, 32) placed thereon, a pull member (3, 33) being attached to the flywheel by means of a free gear mechanism (4, 34) so as to move in a reciprocating manner and a braking band being arranged around the flywheel (2, 32) so as to be pressed against its peripheral surface, whereby the flywheel (2, 32) is arranged to rotate in a predetermined direction when the pull member is pulled and the brake band is arranged to resist the rotational motion of the flywheel, characterized in that the arrangement comprises a relieve means (7, 37) connected to the brake band (6, 36) and to the frame (1, 31) by means of a lever mechanism (9, 39), whereby the pull member (3, 33) is arranged to be pressed against the relieve means (7, 37) during a pulling movement along a direction (A) and to pivot the lever mechanism (9, 39) so that the brake band is tightened against the flywheel (2, 32), the lever mechanism (9, 39) being arranged to pivot so that tightening force exerted by the brake band (6, 36) on the peripheral surface of the flywheel (2, 32) is decreased when the pull member is displaced by the free gear mechanism (4, 34) in a direction (B) opposite to the pulling direction, and a detector (16, 17) connected to the lever mechanism (9, 39) for detecting a number of pivoting movements of the lever mechanism (9, 39).
