Abstract
A vertical four-stroke stepless variable-speed petrol engine belongs to the petrol engine field, wherein a case body is provided with a bearing used to fix a shaft body of an integrated gear on a supporting crankshaft, and the other side of the case body is equipped with a bearing used to fix a supporting shaft body; the shaft body is fixed on the middle of a principal shaft; the principal shaft is a crankshaft; an eccentric shaft is connected with a brace of a piston; the shaft and the gear are integrated as a whole; the gear is meshed with an output shaft gear and an engine oil pump gear; the engine oil pump gear is connected with a shaft of an engine oil pump; an output shaft is supported on the case body by the bearing and fixedly connected with the output shaft gear; the other end of the output shaft is supported on a margin cover by the bearing; and the output shaft is connected with a clutch disk through the key. The cylinder head employs the vertical structure and the first-level decelerating structure output, and the gear on the crankshaft is integrated with the crankshaft. This gear drives the engine oil pump gear and at the same time drives the output shaft gear. In order to realize that the chain wheel on the output shaft revolves in the clockwise direction, according to the gear meshing theory, the gear on the crankshaft revolves in the counterclockwise direction.
Description
Technical field
The utility model relates to a kind of vertical four-stroke stepless speed-variation gasolien engine, belongs to the petrol engine field.
Background technique
Using on the market now mainly is two-stroke stepless speed-variation gasolien engine or four-stroke band gear petrol engine on the outdoor activity car, wherein, the two-stroke stepless speed-variation gasolien engine exists, defectives such as noise is big, and exhaust contaminant exceeds standard, and power is little, and four-stroke band gear petrol engine is a horizontal type structure, gear is arranged again, and using has volume big on the outdoor activity car, defectives such as operation inconvenience.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of vertical four-stroke stepless speed-variation gasolien engine.
The purpose of this utility model is to improve the shortcoming of existing two-stroke gasoline engine and four-stroke gear petrol engine, and has designed a kind of novelly, is particularly suitable for a kind of vertical four-stroke stepless speed-variation gasolien engine of outdoor activity car.
The technological scheme that its technical problem that solves the utility model adopts is: comprise casing, main shaft, lid, oil pump, gear, bent axle, clutch disk, bearing, clutch hoof piece, output shaft, output shaft gear; There is bearing fixing to support the axis body of integrated gear on the bent axle on the casing, opposite side at casing has bearing fixing to support axis body, axis body and axis body are fixed on the middle part of main shaft, main shaft is a crankshaft, its eccentric shaft connects the crank of piston, axis body and gear are one, gear and output shaft gear and oil pump gear engagement, oil pump gear is connected with the axle of oil pump, output shaft by bearings on casing, output shaft is connected with the output shaft gear spline, left side lid is fixedly connected on the casing, and the limit lid is fixedly connected on a left side and covers, and the other end of output shaft is covered on the limit by bearings, output shaft is connected with clutch hoof piece by flat key, and output shaft is connected with clutch disk by needle bearing.
The utility model adopts vertical structure, adopt the output of one-level slowing-down structure, gear and bent axle on the bent axle are made of one, in the time of this gear driven oil pump gear, also drive output shaft gear, in order to realize the sprocket wheel clockwise direction rotation on the output shaft, according to Principles of Gear Connection, the gear on the bent axle must counterclockwise rotation.
The beneficial effects of the utility model, bent axle cog and bent axle is made of one, simultaneously the driving machine oil pump gear, and output shaft gear, the bent axle counterclockwise rotation is vertical structure stepless change four-stroke gasoline engine, advantages such as it is little to have volume, easy to operate, and power is big.
