Problems solved by technology

However, the repeated use of the lever will waste work and time and reduce the efficiency. The movable pulley cannot change the direction of the force, so the independent use is greatly restricted in the mechanical force transmission and it is difficult to achieve the desired effect.

Abstract

The invention discloses a labor-saving rotary power transmission device. The labor-saving rotary power transmission device comprises a power end gear, a load end gear, a lever gear, a support point gear and a lever positioning wheel, wherein the power end gear, the load end gear and the support point gear are connected with the lever gear in a rotary transmission mode, the support point gear is located between the power end gear and the load end gear and is closer to the load end gear, the lever positioning wheel can rotate but can not move, and the lever positioning wheel is connected with the lever gear in a positioning mode so that the lever gear can rotate in a positioning mode. On the basis of direct transmission of a traditional gear, the lever gear, the support point gear and the lever positioning gear are additionally provided, three mechanics principles of a lever, a fixed pulley and a movable pulley are integrated, labor-saving transmission of rotary power is achieved, and the power transmission direction can be changed through simple processing according to needs. The labor-saving rotary power transmission device can be widely applied to rotary power transmission of various machines, meets the requirement for load acting, saves power energy, lowers operation cost, and is favorable for environment protection.

Description

technical field [0001] The invention relates to a power transmission device, in particular to a rotary power labor-saving transmission device. [0002] Background technique [0003] Most of the mechanical power is rotational power, especially the motor as the main power equipment, so most of the mechanical force transmission is the transmission of rotational power. The traditional rotary power transmission is mainly realized by one or more of the transmission shaft, speed changer, gear and chain, etc. The power in the transmission process is consistent, and the effect of labor saving cannot be achieved. Therefore, in order to increase the load power, the motor must be increased. Power means more energy consumption and more waste of resources, which not only fails to save costs, but also is not conducive to environmental protection. [0004] As we all know, both the lever and the movable pulley have the advantage of saving labor. The former increases the length of the mome...
