The invention discloses a rotary connection assembly with rotational degree of freedom in two directions, comprising bearings, a bearing seat and a connecting rod, and further comprising a transverse central shaft and a longitudinal central shaft, wherein a through hole is arranged in the middle of the transverse central shaft along a direction which is vertical to an axis of the transverse central shaft; the longitudinal central shaft passes through the through hole to be crossly connected with the transverse central shaft; the bearing seat is in a hollow framework structure, and the transverse central shaft and the longitudinal central shaft are distributed in the bearing seat; the transverse central shaft is connected with the bearing seat through transverse bearings and is transversely arranged in the bearing seat; one end of the connecting rod is in a hollow cylinder structure; the transverse central shaft is provided with a rectangular through hole which is matched with the cylinder structure; the connecting rod is arranged on the longitudinal central shaft in a penetrating manner through a longitudinal bearing, and is connected with the longitudinal central shaft; and the connecting rod can transversely rotate within a certain angle along the axis of the transverse central shaft and can rotate within a certain angle in the bearing seat along the axis of the longitudinal central shaft. The connection assembly has the characteristics of compact structure, fewer parts, easiness for arrangement and low cost, and can be applied to the field of an inclined plate or swinging plate type transmission form engine, such as a Stirling engine.
Description
technical field [0001] The invention relates to a linear-rotary motion conversion mechanism component, in particular to a rotational connection assembly with two rotational degrees of freedom, that is, a bearing assembly, which is applied to the field of axial transmission mechanisms such as swash plate or wobble plate. Background technique [0002] Axial transmission mechanisms such as swash plate or wobble plate are common components that convert linear reciprocating motion into rotary motion, such as swash plate or wobble plate transmission structure In Stirling engines, the transmission mechanism mostly adopts swash plate or wobble plate structure , the running direction of the piston is the same as the axial direction of the output shaft, which makes the layout compact and is conducive to the miniaturization design of the engine. Therefore, the conversion mechanism components of the linear-rotary motion of the piston are particularly important, and the bearing assembly i...
