Reducer

Abstract

The invention relates to an reducer, in particular to a mechanical device for automatically reducing speed without energy consumption, comprising an air cylinder and a piston, wherein the piston is movably connected with the upper part of a connecting rod, and the lower part of the connecting rod is connected with a crankshaft. The energy consumption free reducer is characterized in that an air hole is arranged at the upper part of a closed cylinder body of the air cylinder. The crankshaft is a part for receiving input power. When the crankshaft rotates, and the connecting rod drives the piston to compress or enlarge an air chamber space of the air cylinder, an air chamber of the air cylinder can form pressure difference with the atmosphere. By adopting an air cylinder action principle and utilizing the ventilation volume of the air hole, the pressure difference of air is formed, and the resistance is obtained to realize the purpose of speed reduction. The invention does not need newly added power and has the advantages of almost non energy consumption, simple structure and free maintenance.

Description

technical field [0001] The invention relates to an automatic deceleration mechanical device. Background technique [0002] Most of the current reducers are energy-consuming mechanical devices that require power supply and have a relatively complex structure. And some other energy-saving reduction devices also exist, such as the use of inertial damping principle and variable speed gear train to achieve deceleration, and the use of electromagnetic cutting deceleration technology to achieve deceleration, etc. These reducers have complex structures, high costs, poor stability and manufacturing costs. and high maintenance costs. [0003] The Chinese invention patent application number is 200610109216.7, which discloses a non-energy-consuming automatic force reduction and reducer. It is to set two identical transmission gears on both sides of the main gear that receives the input power, and communicate with the corresponding transmission components (bearings and gears) The two s...
