A device that converts circular rotation into linear reciprocating motion

Abstract

The invention discloses a device converting circular rotation to linear reciprocating motion. The device overcomes the defect in the prior art that the relative frequency of the motion of a sliding block driven by a connection rod of a crank connection rod mechanism can not be accelerated. The device comprises a connection rod, wherein the rear end of the connection rod is in pin joint connection with a dragging piece and the front end of the connection rod is rotably connected with the lower end portion of a swing rod through a pin shaft, and the swing rod is arranged above the connection rod. The upper end portion of the swing rod is rotably connected with a pin rod fixed to a base; a stirring wheel with at least two teeth is arranged below the front end of the connection rod; the stirring teeth of the stirring wheel abut against the pin shaft in an interval mode; the stirring wheel is fixedly connected with a rotating shaft, and the rotating shaft is connected to the base through a bearing; the rotating shaft is connected with a transmission mechanism; the lower end portion of the swing rod abuts against one end of a compression spring, and the other end of the compression spring abuts against a spring seat arranged on a clutch. The device converting circular rotation to linear reciprocating motion is used for frequency-increasing swing reciprocating transmission devices and has the advantages of improving the reciprocating travel frequency of sliding blocks, being very small in sliding block side component force and small in power waste, and reducing abrasions and heating of relevant parts.

Description

technical field

[0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a frequency-increasing swing reciprocating transmission device. Background technique

[0002] In the prior art, the transmission mechanism that converts circular motion into linear reciprocating motion, such as the crankshaft-connecting rod mechanism, generally drives the slider to reciprocate once when the crankshaft rotates once, and the rotating frequency is the same as the reciprocating frequency. Improving the relative frequency of the reciprocating movement of the slider relative to the rotation of the crankshaft cannot be achieved simply by relying on the existing crankshaft linkage mechanism; The connecting rod will swing up and down, and there is a lateral component of the thrust of the crankshaft on the slider through the connecting rod. This lateral component will cause pressure and huge friction on the slide rail that cooperates with the...
