Abstract

The invention discloses a transmission device based on the lever principle, and relates to a transmission device, in particular to the transmission device based on the lever principle. The invention aims to solve the problems that the existing hoisting equipment applying the lever principle is relatively complex in structure, relatively large in size and not suitable for being used in families and life. The transmission device comprises a vertical frame, a base, a hoisting chain wheel mechanism, a hoisting hook, a cross beam, a counterweight, a pulley, a pulley yoke, a pull rope and a hoisting rope, the base is horizontally arranged, the vertical frame is vertically installed on the base, the hoisting chain wheel mechanism is installed on the vertical frame, the hoisting hook is connected with the hoisting chain wheel mechanism through the hoisting rope, the cross beam is horizontally arranged, one end of the cross beam is connected with the hoisting chain wheel mechanism, the other end of the cross beam is connected with the balance weight, and the pulley is installed at the upper end of the vertical frame through the pulley yoke, the pulley is connected with the other end of the beam through a pull rope. The invention belongs to the field of transmission machinery.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device based on a lever principle, and belongs to the mechanical field. Background technique [0002] Lever is further divided into labor-saving lever, labor-saving lever and equal-arm lever. The principle of leverage is also called "lever balance condition". For a lever to be balanced, the two moments (the product of the force and the moment arm) acting on the lever must be equal in magnitude. That is: power × power arm = resistance × resistance arm, expressed as F in algebraic formula 1 ·L 1 =F 2 ·L 2 . In the formula, F 1 Indicates power, L 1 Indicates the power arm, F 2 Indicates resistance, L 2 Indicates the resistance arm. It can be seen from the above formula that to balance the lever, the power arm is several times the resistance arm, and the resistance is several times the power. The principle of leverage is widely used in lifting equipment. The existing...
