Problems solved by technology
The various bodies provided by the prior art have not seriously considered this problem
Especially after the cylinder head is fixed on the top surface and / or bottom surface of the body, in order to fix the cylinder head, the cylinder head bolts will generate tensile stress on the body, which will cause the second reciprocating track (i.e. the runway) of the dynamic balance slider to be placed. ) deformation, which will affect the normal reciprocating motion of the dynamic balance slider in severe cases

Embodiment Construction
[0027] Please see figure 2 , which is a perspective view of the H-shaped airframe provided by the embodiment of the present invention. Also see image 3 , the graph is figure 2 The perspective view of the shown body observed from another angle, its outward end face is figure 2 in the top surface. In the above drawings, in addition to the reinforcing rib part, and in the background technology figure 1 The body shown is basically the same as a whole, and in the following description, the same as figure 1 The same parts are shown with the same reference numerals. The figure shows the outline of the internal combustion engine block as roughly cuboid. For the convenience of explanation, figure 2Mark the three dimensions of the cube in space, which are up-down dimension I, front-back dimension II, and left-right dimension III. Correspondingly, several surfaces of the machine body are top surface, bottom surface, front end surface, rear end surface, left side and right si...

The invention provides an H-shaped machine body for a mutual conversion mechanism of reciprocation-rotation motion. Two transverse ribs which are connected with a left side surface flange and a right side surface flange and extend toward axial directions of a first reciprocating motion track and a third reciprocating motion track are arranged on the top surface or the bottom surface of the machine body; the transverse ribs are arranged at both sides of a salient part or a position located by vertical projection of the second reciprocating motion track on the top surface or the bottom surface;and a plurality of reinforcing ribs used for connecting the two side surface flanges with the transverse ribs are arranged between the two side surface flanges and the transverse ribs and do not passthrough the salient part or the position located by the vertical projection of the second reciprocating motion track on the top surface or the bottom surface. In the H-shaped machine body, by arranging the transverse ribs and the reinforcing ribs on the top surface and / or the bottom surface, the pretightening force or the tensile stress borne by the whole machine body along the axial direction ofan air cylinder is mainly borne by the transverse ribs and the reinforcing ribs, and therefore, the deformation of the second reciprocating motion track is efficiently lowered, and a reciprocating motion element moved in the second reciprocating motion track can not have the phenomenon of clamping stagnation in reciprocating motion.
Description
technical field [0001] The invention relates to a reciprocating-rotational mutual conversion mechanism, in particular to an H-shaped machine body used for the reciprocating-rotational mutual conversion mechanism. The present invention also relates to a device using the H-shaped body. Background technique [0002] In mechanical equipment, it is necessary to realize mutual conversion between reciprocating motion and rotary motion in many occasions. For example, a reciprocating internal combustion engine needs to convert the reciprocating linear motion of the piston driven by the explosive pressure of the combustible mixture into the rotational motion of the crankshaft; on the contrary, the compressor needs to convert the rotation of the crankshaft driven by an external electric motor into the reciprocating linear motion of the piston . The above two conversions have the same kinematic requirements for the mechanism except for the different active parts. Therefore, the mechan...
