T-shaped crank round sliding block mechanism, internal combustion engine and compressor

Abstract

The invention provides a T-shaped crank round sliding block mechanism. The mechanism comprises a bifurcated single-acting piston and a double-acting piston, wherein the guiding part of the bifurcated single-acting piston is divided into a first row guiding part and a second row guiding part which are parallel to each other by a longitudinal groove; the first row guiding part is provided with a first round sliding block accommodating hole, the second row guiding part is provided with a second round sliding block accommodating hole, and the two holes are used for accommodating a first round sliding block and a second round sliding block respectively; the guiding part of the double-acting piston is inserted into the longitudinal groove of the bifurcated single-acting piston and is provided with a middle round sliding block accommodating hole, and the double-acting piston is vertically crossed with the bifurcated single-acting piston; and the first round sliding block and the second roundsliding block are arranged in an inphase mode, a middle round sliding block is sandwiched between the first round sliding block and the second round sliding block and is arranged in a phase difference of 180 degrees with the two sliding blocks, and adjacent round sliding blocks are fixed with each other. The structure can reduce bending moment along the axis of a crankshaft.

Description

technical field [0001] The invention relates to a crank circular slider mechanism, in particular to a T-shaped crank circular slider mechanism. The present invention also relates to an internal combustion engine and a compressor using the T-shaped crank circular slider mechanism. Background technique [0002] The kinematic mechanism of a traditional engine is a crank linkage mechanism. Under this kind of kinematic mechanism, the reciprocating motion of the piston needs to be transmitted to the crankshaft through the connecting rod connected to it. During the movement, the connecting rod swings back and forth with the movement of the piston, so that the piston is subjected to a periodic change with a higher-order function. lateral force. [0003] Due to the existence of the connecting rod, the internal combustion engine of the crank connecting rod mechanism has disadvantages such as bulky, heavy, and poor balance performance. The characteristic is that the connecting rod i...

Problems solved by technology

However, the good dynamic balance effect of this mechanism depends on the intermediate reciprocating parts it sets. The whole mechanism is too complicated, and the number of reciprocating elements is increased, and the length of the crank pin needs to be increased, resulting in a decrease in the stiffness of the shafting system.

In addition, the manufacturing cost of the machine has increased significantly, and the reliability has also decreased
