Abstract

The utility model provides a device for conversion from reciprocating motion to rotary motion. A swing arm (1.2) performs reciprocating motion and drives a gear (2.2) through a sector gear (1.3) and further drives a flywheel (4.2), and simultaneously a gear (2.4) drives a gear (3.4) and further drives a flywheel (4.4). The flywheels are provided with ratchet wheel and pellet mechanisms. The direction of rotation of the flywheel (4.2) driven by the gear (2.2) is opposite to the direction of rotation of the flywheel (4.4) driven by the gear (3.2) and drive directions of ratchet wheels of the flywheel (4.2) and the flywheel (4.4) disposed on a shaft (4.3) are the same, the ratchet wheel and a pellet on a flywheel being in an engaged state and the ratchet wheel and a pellet on the other flywheel in a disengaged state, so that the flywheel (4.2) and the flywheel (4.4) drive the shaft (4.3) to rotate ceaselessly in a reciprocating and alternative manner. The device for conversion from reciprocating motion to rotary motion is characterized by large torque and stable and continuous rotation.

Description

A kind of to-and-fro motion converts the device that rotatablely moves into

One, technical field

The utility model relates to and a kind ofly converts the device that rotatablely moves into by the swing arm to-and-fro motion, belongs to mechanical transmission fields.

Two, background technique:

Existingly convert in the device that rotatablely moves by to-and-fro motion; Hand-clasping type charger for mobile phone and hand-clasping type power generation flashlight are more typically arranged; Yet have only the motion of direction to be used for the live axle rotation in its swing arm to-and-fro motion; Other direction only is the motion that swing arm resets, and this type of to-and-fro motion converts the device that rotatablely moves into still has more deficiency:

1, this type of to-and-fro motion converts the active force that the device that rotatablely moves only has unidirectional drive into.

2, this type of to-and-fro motion converts the device that rotatablely moves into and can cause driving torque non-constant, and rotating speed is not steady, is intermittent driving phenomenon.

3, this type of to-and-fro motion converts the conversion that the device that rotatablely moves can't be realized big torque movements into.

Three, summary of the invention

(1), goal of the invention:

The object of the invention mainly provides and a kind ofly converts the device that rotatablely moves into by the swing arm to-and-fro motion, and it is big that it has a torque, and rotation continues characteristic stably.

(2), technological scheme:

The method that the utility model solves its technical problem is: the gear train that assembles (1); Gear train (2); Gear train (3), the bearing on the gear train (4) be assembled to respectively with gear-box in the corresponding bearing support, make gear (2.2) engagement in tooth sector (1.3) and the gear train (2) in its gear train (1); Gear (2.2) again with gear train (4) in flywheel (4.2) engagement; Gear (2.4) in the gear train (2) and the engagement of the gear (3.4) in the gear train (3) simultaneously, flywheel (4.4) engagement in gear (3.2) and the gear train (4) has ratchet and pawl mechanism on described flywheel (4.2) and the flywheel (4.4).Swing arm (1.2) on the gear train (1) moves reciprocatingly through tooth sector (1.3) actuation gear (2.2) and then drives flywheel (4.2) to-and-fro motion; Gear (2.4) actuation gear (3.4) drives flywheel (4.4) to-and-fro motion by gear (3.2) more simultaneously; Because the moving direction that is transferred between flywheel (4.2) and the flywheel (4.4) is to replace reciprocal moving direction; And the rotary driving direction when being assembled in its ratchet and pawl engagement of flywheel (4.2) and flywheel (4.4) on the axle (4.3) is consistent; Ratchet and pawl on one of them flywheel is an engagement; And the ratchet and pawl on another flywheel is a separated state; Therefore be the to-and-fro motion of being transmitted between flywheel (4.2) and the flywheel (4.4), make flywheel (4.2) replace engagement and separate to come live axle (4.3) to continue rotation by the ratchet and pawl on the flywheel to replace reciprocal motion mode with flywheel (4.4) according to swing arm (1.2).

(3), invention effect:

The utility model the most directly effect be exactly through swing arm move reciprocatingly convert into have big torque, motion that rotation steadily continues, especially convert to-and-fro motion into rotatablely move device and mix speed changer and use the power source that can be used as electromechanical equipments such as generator.
