Mechanical rectification mechanism

Abstract

The invention provides a mechanical rectification mechanism, and relates to the technical field of mechanical design. A front cover and a rear cover are both of a two-step ladder disc type structure,and an input shaft is provided with a stepped shaft of a shaft shoulder. An inner ring of a first supporting bearing is in interference fit with the outer diameter of the input shaft, and an outer ring is in interference fit with the inner diameter of the first step of the front cover. An inner ring of a first one-way bearing cooperates with the middle of the input shaft through a key, and the rear end face of the first one-way bearing closely abuts against a front shaft shoulder. An inner ring of a second one-way bearing cooperates with the rear part of the shaft shoulder of the input shaft through a key. An outer ring of the second one-way bearing is connected with the inner diameter of the front end of a boss gear through a key. An inner ring of a fourth supporting bearing is in interference fit with the outer diameter of the middle of an output shaft, and the outer diameter is in interference fit with the inner diameter of the first step of the rear cover. A small gear with one side engaged with the boss gear is arranged on the front portion of a transmission shaft, the other side of the small gear is engaged with an inner gear ring, and the outer diameter of the inner gear ring is in interference fit with the inner diameter of a second supporting bearing. A connecting rod is of a special-shaped rod structure, and through holes in the two ends are fixedly connected with theinner gear ring through bolts.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and mechanism design. Background technique [0002] The mechanical rectification mechanism is currently widely used in new energy collection equipment, such as wind energy, wave energy and mechanical energy. Transforming into a one-way, regular motion form has a significant effect on improving energy conversion efficiency and improving motor life. At present, in wind energy collection equipment, in some fan types, different wind directions drive the main shaft to rotate in two directions, which is converted into one-way rotation by means of a mechanical rectification mechanism, and the one-way torque is transmitted to the motor shaft to generate power; in wave energy collection equipment , the wave excites the float to reciprocate up and down, which is converted into bidirectional rotation of the main shaft through the reversing mechanism internally, and the uninterrupted one-way torque...

Problems solved by technology

[0003] After investigation and retrieval, there are currently authorized and used mechanical rectification mechanisms. For example, the publication number is CN104863810A. This patent designs an energy harvesting device for rail vibration energy. The two-way rotation of the output shaft is converted into the one-way rotation of the output shaft through a mechanical rectification wheel system, thereby driving the motor shaft to rotate in one direction to generate electricity. However, the mechanical rectification equipment involves multi-stage gear transmission, using a total of 10 gears, and the assembly is complex and the transmission efficiency is low.

At present, most mechanical rectification equipment is designed for equipment with reciprocating motion input. Most of them are designed to match or integrate with the usage scenarios and equipment installation methods. Modular design cannot be achieved, and there are limitations.

In addition, power generation or new energy collection equipment with possible bidirectional rotation input has broad application prospects, such as modular design of wind energy collection equipment, bidirectional rectification of inertial energy collection equipment for trains and automobiles, collection of wave energy and environmental mechanical energy self-supply equipment. Two-way rectification, etc.; and the conversion efficiency of existing energy harvesting equipment largely depends on the efficiency of the transmission system and rectification system of the equipment, so it is necessary to design an easy-to-modular, simple structure, high transmission efficiency for this situation.
