Abstract

The invention discloses a double-shaft transmission phase angle adjustable device, the structure of which comprises a bearing shaft and a sheathing shaft, a first control disk, a second control disk, a first taper gear and a second taper gear; the bearing shaft is provided with an exhaust cam, the sheathing shaft is arranged on the bearing shaft and is provided with an exhaust cam, the first taper gear and the second taper gear are arranged on the first control disk and the second control disk by a first hinge pin and a second hinge pin, a first contact thrust bearing and a second contact thrust bearing; the first taper gear and the second taper gear are respectively arranged at two sides of the first control disk and the second control disk to form a hinged pair of a third taper gear and a fourth taper gear, and a hinged pair of a fifth taper gear and a sixth taper gear; the fifth taper gear and a timing gear between the fifth taper gear and the fourth taper gear are both fixed and connected to the fourth taper gear; the peripheries of the first control disk and the second control disk are respectively connected to the first control piece and the second control piece; the outside of the sixth taper gear is fixed by an elastic gasket and a fixing nut. The invention has the advantages of high performance, low cost, lower aeration loss of internal-combustion engines, higher aeration efficiency, lower exhaust pollution and enhanced power performance.

Description

technical field [0001] The present invention relates to a mechanical device, more specifically, the present invention relates to a dual-shaft transmission phase angle adjustable device for a mechanical system or an internal combustion engine. Background technique [0002] Mechanical systems, including internal combustion engines, often require changing the phase angle between two rotating shafts to improve performance. For example, in traditional internal combustion engines, due to structural limitations, the phase angle between the crankshaft and the intake and exhaust camshafts is constant, and the relative axial positions of the two cannot be adjusted during operation, which limits the improvement of its performance. The result is that the power, economy and emission indicators of the engine are not optimized, resulting in poor power performance, high fuel consumption and worsening emission indicators. [0003] With the advancement of science and technology, although the...
