Problems solved by technology
Since each crank pin is eccentric in a different direction, it is not possible to insert the eccentric disk into the crankshaft component from the axial direction and assemble it. Each eccentric disk is constructed by butting two semicircular parts divided in the radial direction and fastening them with bolts.
If the eccentric disc is formed into a butt joint structure of two semicircular parts, when a large torque or load acts on the continuously variable transmission mechanism, the two semicircular parts will act on the direction of mutual separation and open. , which may adversely affect the dimensional accuracy of the inner diameter of the through-hole through which the crankpin passes.
In addition, there is a concern that the production cost will increase, such as an increase in the number of parts and an increase in assembly man-hours.

Embodiment Construction
[0069] First, refer to Figure 1 to Figure 13 A reference example having the same basic structure as the continuously variable transmission mechanism of the present invention will be described.
[0070] The continuously variable transmission mechanism of the reference example is a type of transmission mechanism called IVT (Infinity Variable Transmission = a transmission mechanism that makes the transmission ratio infinite without using a clutch to make the output rotation zero). The continuously variable transmission mechanism BD is configured such that the continuously variable transmission mechanism BD can change the gear ratio i steplessly, and can set the maximum value of the gear ratio to infinity (∞).
[0071] Such as figure 1 As shown, the continuously variable transmission mechanism BD includes: an input shaft 151, which is connected to an output shaft S of a drive source such as an engine, and rotates about the input center axis O1 by receiving the rotational power of the d...

The invention provides a continuously variable transmission mechanism capable of suppressing deterioration of inner diameter dimension accuracy of an open hole through which a crank pin is penetrated by opening of an eccentric disk. First and second crank journals 16p-16v, 17p-17v are respectively provided so that a projection portion N1 where the first and second crank journals 16p-16v, 17p-17v are projected along an axial direction is positioned in contours N2 of first and second crank pins 16p-16v, 17p-17v to which the first and second crank journals 16p-16v, 17p-17v are connected. An axial width L1 of an eccentric disk 14 is made smaller than an axial length L2 of the first and second crank journals.
Description
Technical field [0001] The present invention relates to a crank-type continuously variable transmission mechanism that converts the eccentric rotation of an eccentric disk rotating with an input shaft into reciprocating oscillation of an input member of a one-way clutch via a connecting member, and transmits the reciprocating oscillation of the input member via the one-way clutch Converted to unidirectional intermittent rotation of the output shaft, the present invention particularly relates to a continuously variable transmission mechanism capable of continuously changing the eccentricity of a continuously variable transmission. Background technique [0002] Patent Document 1 describes a continuously variable transmission that converts the rotation of the input shaft connected to the engine into the reciprocating motion of the connecting rod, and further converts the reciprocating motion of the connecting rod into rotational motion of the output shaft through a one-way clutch.
