Abstract
The utility model provides a non-connecting rod piston apparatus directly driven by a crankshaft on the combustion engine, which is used for the mutual conversion of the straight reciprocating motion of the piston and the rotation motion of the crankshaft. Each of the two air cylinders in opposite arrangement with center lines shifting a certain distance, is provided with a piston whose ends can extend along the radial direction; The ends of the two pistons are connected with the spacer block by screw rods; the wind axis bearing makes movement in the raceway formed by the spacer block and the piston extending along the radial direction. The utility model has the advantages that the piston has excellent guidance quality in the air cylinders; the radial force of the piston suffered is small when in work; the wear between the pistons and the cylinder wall is small; the non-connecting rod tandem double-piston apparatus has high heat efficiency.
Description
The utility model relates to a kind of no link gearing of explosive motor, is used for the no link gearing in the mutual conversion, particularly two-stroke internal combustion engine that rotatablely move of the straight reciprocating motion of piston and bent axle.
Existing reciprocating internal combustion engine adopts connecting rod to realize straight reciprocating motion and the mutual conversion that rotatablely moves, and the component that this mechanism does relative movement are many, and inner friction loss is big, the balance difficulty.For addressing this problem, the someone has designed no link gearing, realizes the mutual conversion of reciprocating motion of the pistons and crankshaft rotating motion with eccentric disc connection piston and bent axle.The piston of this structure, stroke is restricted, and the activity of bent axle is limited in the scope less than piston diameter.
The purpose of this utility model provides the no link gearing that a kind of piston stroke is not greatly reduced by structural limitations, radial force that piston bore.
Technical solution of the present utility model is such: arrange two subtends, in the cylinder of its disalignment certain distance, the piston that respectively has an end radially to extend, the not end of two-piston links to each other with cushion block with screw rod, and crankshaft bearing just moves in by cushion block and the piston raceway that radially extension part constitutes at this.
Because two pistons have the structure that an end radially extends, thereby the stroke of piston can not be subjected to the restriction of structure, can set up on their own as required, not resemble the prior art piston and radially do not having extension part, thereby the activity of bent axle is limited in the scope less than piston diameter; Its center line of cylinder that subtend is arranged on two is along the tangential skew certain distance of bent axle circumference besides, and the radial force that is subjected to when making pistons work greatly reduces, and can prevent that piston from rotating in cylinder.In addition, piston has fabulous guidance quality in cylinder, thereby the life-span is long, reliable operation, and it is little to wear and tear between piston and the casing wall, thermal efficiency height.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A sectional view.
Now in conjunction with the accompanying drawings the utility model is made detailed description:
No connecting rod tandem double-piston device has one to have the housing 6 that two subtends are arranged cylinder, the axis of two subtend arrangement cylinders does not overlap, the cylinder-bore axis of two skews is along the tangential skew of bent axle 4 circumference, and promptly the plane that cylinder-bore axis constituted of two skews is perpendicular to the axis of bent axle 4.Housing 6 is provided with left end cap 9 that has bearing 8 and the right end cap 10 that has bearing 11, in the cylinder body of housing 6, be provided with left piston 1 and right piston 7, left piston 1 and right piston 7 be not provided with upper and lower two cushion blocks 2 between the end, by screw rod 3 left piston 1, right piston 7 and cushion block 2 are connected as a single entity.Bent axle 4 is made up of left bent axle 14 and right bent axle 12, left side bent axle 14 and right bent axle 12 are installed in bearing 8 and the bearing 11, left side bent axle 14 is connected by tensioner screw 13 with right bent axle 12, bent axle 4 passes the raceway of being made up of left piston 1, right piston 7 and cushion block 2, bent axle 4 is provided with roller bearing 5, and the roller bearing 5 on the bent axle 4 the end motion of left piston 1 and right piston 7 at the raceway inner close fitting that is made of left piston 1, right piston 7 and cushion block 2.
