Abstract
The invention discloses a portable engine installation of electric generator, comprising air cylinder in head and crankshaft in box. The piston in cylinder drives crankshaft, which drives cam shaft through gear, through connector. The cam on cam shaft drives tapper arm, which drives pushing bar. The pushing bar controls switch of air gate through swing arm. There are two paralleling said cam shafts, which are parallel to crankshaft respectively. One cam is set on each cam shaft. Previous mechanism can not only reduce the cubage of crankshaft box but also accelerate heating of cylinder head dispersed.
Description
Technical field
The present invention relates to a kind of engine device of portable electric generator.
Background technique
Portable electric generator in the market comprises motor and by engine-driven generator, and both can be installed in the sound insulation casing that top is provided with lifting handle, carry to make things convenient for the user.Traditional motor comprises the cylinder head cylinder on top and the crankcase of bottom, cylinder head is provided with cylinder, the upper end of cylinder is provided with intake valve and exhaust valve, and the piston in the cylinder drives the bent axle that is positioned at the below by connecting rod, drives generator by bent axle and generates electricity, simultaneously, also by the camshaft of gear driven setting in parallel, camshaft is provided with two cams to bent axle, and two cams contact the tappet on top respectively, tappet contacts the push rod on top, and push rod drives valve switch by rocking arm.The shortcoming of this structure is:
1, because two cams are arranged on the camshaft, so the length of camshaft is long, cause the volume ratio of crankcase bigger, this is totally unfavorable for portable electric generator.
2, since camshaft and bent axle be arranged in parallel, two cams are positioned on the camshaft, so the line between two valves is also inevitable parallel with camshaft, and the wind direction of cooling air is also parallel with camshaft with bent axle in the unit, therefore, cooling air is to walk along the line between two valves, and this heat radiation for cylinder head is totally unfavorable.
Summary of the invention
The present invention seeks to: a kind of engine device of portable electric generator is provided, and this device is provided with two camshafts parallel with bent axle, and a cam is set respectively on two camshafts, not only can dwindle the volume of crankcase, but also helps the cylinder head heat radiation.
Technological scheme of the present invention is: a kind of engine device of portable electric generator, comprise cylinder that is positioned at cylinder head and the bent axle that is positioned at crankcase, piston in the cylinder drives bent axle by connecting rod, bent axle is by the gear driven camshaft, and the cam on the camshaft contacts tappet, and tappet contacts push rod, push rod is by the switch of rocking arm control valve, described camshaft has two, and two camshafts be arranged in parallel with bent axle side by side and respectively, and every camshaft is provided with a cam.
The further technological scheme of the present invention is: a kind of engine device of portable electric generator, comprise cylinder that is positioned at cylinder head and the bent axle that is positioned at crankcase, piston in the cylinder drives bent axle by connecting rod, bent axle is by the gear driven camshaft, and the cam on the camshaft contacts tappet, and tappet contacts push rod, push rod is by the switch of rocking arm control valve, described camshaft has two, and two camshafts be arranged in parallel with bent axle side by side and respectively, and every camshaft is provided with a cam; Be fixed with driving gear on the described bent axle, driving gear meshes with being fixed therein a driven gear on the camshaft, and two camshafts are fixed with intermeshing driving gear respectively.
The more detailed technological scheme of the present invention is: a kind of engine device of portable electric generator, comprise cylinder that is positioned at cylinder head and the bent axle that is positioned at crankcase, piston in the cylinder drives bent axle by connecting rod, bent axle is by the gear driven camshaft, and the cam on the camshaft contacts tappet, and tappet contacts push rod, push rod is by the switch of rocking arm control valve, described camshaft has two, and two camshafts be arranged in parallel with bent axle side by side and respectively, and every camshaft is provided with a cam; Be fixed with driving gear on the described bent axle, driving gear meshes with being fixed therein a driven gear on the camshaft, and two camshafts are fixed with intermeshing driving gear respectively; Cam on described two camshafts is positioned at same plane, and this plane is vertical with camshaft with bent axle; Line between described two valves is vertical with camshaft with bent axle.
Advantage of the present invention is:
1. because the present invention is provided with two camshafts parallel with bent axle, a cam is set respectively on two camshafts, therefore, has shortened the length of camshaft, reduced the volume of crankcase, alleviated the weight of generator set, be convenient to the user and carry.
2. because two camshafts are set up in parallel, two cams are positioned at same plane, therefore, line between two valves and bent axle and camshaft are perpendicular, just the wind direction with cooling air is vertical, has compared with prior art turned over 90 degree, thereby helps the heat radiation of cylinder head.
