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

The invention provides a V-shaped crank circular slider mechanism comprising two single-acting pistons, the two single-acting pistons are distributed in a V shape and include a double-row piston and a single-row piston; a guide part of the double-row piston is separated into two rows of mutually parallel branches through a longitudinal groove; the first-row guide part is provided with a first circular slider containing hole, the second-row guide part is provided with a second circular slider containing hole, and a first circular slider and a second circular slider are respectively arranged inthe first circular slider containing hole and the second circular slider containing hole; the guide part of the single-row piston is inserted into the longitudinal groove of the branched piston, vertically crossed with the branched piston and provided with a middle circular slider containing hole; the first circular slider and the second circular slider are arranged in phase, a middle circular slider is clamped between the first circular slider and the second circular slider and arranged at the phase difference of 180 degrees with the two circular sliders, and adjacent circular sliders are mutually fixedly connected. The V-shaped crank circular slider mechanism can reduce the bending moment generated by the reciprocating inertia force of a reciprocating part on an axial line of a bent axle.
Description
technical field [0001] The invention relates to a crank circular slider mechanism, in particular to a V-shaped crank circular slider mechanism. The present invention also relates to an internal combustion engine and a compressor using the above-mentioned V-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 ...
