Abstract
The utility model relates to a combined crankshaft with conical surface pins for a small internal combustion engine, which belongs to the technical field of a crankshaft for an internal-combustion engine. The utility model aims to solve the technical problem of providing the combined crankshaft of which the left crank eccentric hole and the right crank eccentric hole have favorable concentricity with connecting pins. To solve the technical problem, the utility model has the technical proposal that the combined crankshaft with conical surface pins comprises a left crank, a right crank, conical surface pins and a piston connecting rod, wherein, the left crank and the right crank are respectively provided with an eccentric hole of which the inner surface is conical; the middle segment of each conical surface pin is cylindrical and is arranged in holes of the piston connecting rod, and the left segment and the right segment of each conical surface pin are cones corresponding to conical eccentric holes of a left crankshaft and a right crankshaft and arranged in the eccentric holes of the left crank and the right crank. The utility model can be sued for a crankshaft of an internal-combustion engine, and has the advantages of good concentricity and enlarged torque.
Description
One, technical field
The utility model belongs to the I. C. engine crankshaft technical field.
Two, background technique
The normal vuilt-up crankshaft that is assembled into by left crank, right crank and connecting pin that adopts of the bent axle of compact internal combustion engine.Its advantage is easily manufactured, is suitable for producing in enormous quantities, can save material.Deficiency is the influence that the concentricity of the axis of the axis of left crank eccentric opening, right crank eccentric opening and cylindrical connecting pin is subjected to machining accuracy and mounting technology, does not often reach requirement, and work is bad when causing moving.
Three, summary of the invention
Technical problem to be solved is, provides the axis of a kind of axis of the eccentric opening that makes left and right crank and connecting pin to have the vuilt-up crankshaft of the compact internal combustion engine with conical surface pin of good concentricity.
The technological scheme that solves this technical problem is as follows: have the vuilt-up crankshaft of the compact internal combustion engine of conical surface pin, comprise left crank, right crank, conical surface pin and piston rod.The axle of left side crank and right crank is contained on the internal combustion engine cylinders with bearing, and it is conical eccentric opening that internal surface is arranged on left crank and the right crank.Conical surface pin is divided into three sections, wherein section surface is a cylindrical body, its left side section and right section for left crank and the right crank upper inner surface corresponding conically shaped body of cone angle that is conical eccentric opening, left side section is loaded on respectively in left crank eccentric opening and the right crank eccentric opening with right section conically shaped body, and its stage casing is loaded in the tie rod holes of piston rod with connecting rod bearing.The left and right two ends of taper pin can also be connected with right crank with left crank.
Beneficial effect: the utility model is used for compact internal combustion engine.Its beneficial effect is the good concentricity between the axis of eccentric opening of the axis of conical surface pin and left and right crank, and is stable, can increase moment of torsion.
Four, description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 1 is described as follows: 1 is that left crank, 2 is that right crank, 3 is that conical surface pin, 4 is that piston rod, 5 is that eccentric opening, 6 is that conically shaped body, 7 is that bearing, 8 is that tie rod holes, 9 is a connecting rod bearing.
Five, embodiment
The axle of left side crank 1 and right crank 2 is contained on the cylinder body with bearing 7.All have on a left side crank 1 and the right crank 2 internal surface for its cone angle be 1 ° 20 ' conical eccentric opening 5.Conical surface pin 3 is divided into three sections, and its stage casing is that cylindrical body is loaded in the tie rod holes 8 of piston rod 4, and the load rod bearing 9 therebetween; Left side section and right section for cone angle be 1 ° 20 ' conically shaped body 6, eccentric opening 5 dresses of left side section and left bent tenon 1 close, the right section eccentric opening 5 with right crank 2 adorned and closed.
