Embodiment

[0033] To transform the popular traditional piston diesel engine: the hypocycloidal energy conversion mechanism replaces the traditional crank connecting rod mechanism.

[0034] Such as image 3 , 4 As shown; according to the balance piston reciprocating inertial force of the eccentric dual-axis mechanism, the size of the balance shaft 14 is adjusted to meet the requirements of the balance piston reciprocating inertial force, and the shape and installation size of the box body 5 and the piston 6 can remain unchanged. Put the left crankshaft 8 and the right crankshaft 11 into the left and right bearings of the original crankshaft in the casing 5 respectively to ensure firm and stable operation. Will Figure 6The ring gear 10 shown is fixed on the lower part of the case body 5 by means of bolts and positioning pins. The left crankshaft 8 and the right crankshaft 11 are respectively connected with the middle eccentric crankshaft 13 through two sliding bearings 17 to form a rot...

Abstract

The invention discloses a hypocycloid single cylinder diesel which replaces the traditional crank link mechanism with a set of novel hypocycloid energy transformation mechanism to realize the interconversion of the complete linear movement of the piston and the rotary movement of the crankshaft and to output power. A left crankshaft (8) and a right crankshaft (11) of the hypocycloid energy transformation mechanism are respectively mounted at the left and right sides of a case (5) by bearings; the left crankshaft (8) and the right crankshaft (11) are respectively connected with a central eccentric crank shaft (13) by two slide bearings (17); two planet gears (9) are provided in the invention which are fixed at the two ends of the central eccentric crank shaft (13); the two planet gears (9) are respectively meshed with two annular gears fixed at the case to form two pairs of gears. Compared with the traditional crank link mechanism type single cylinder diesel, the hypocycloid single cylinder diesel eliminates the side pressure of the piston on the cylinder, has the advantages of high transmission efficiency, low fuel oil consumption and high output power.

Description

technical field [0001] The invention relates to a diesel engine, in particular to a hypocycloid single-cylinder diesel engine. Background technique [0002] At present, piston internal combustion engines are widely used in various industries such as sea, road and air transportation, agricultural machinery, construction machinery and power generation. but in such figure 1 In this piston type internal combustion engine shown, comprise casing 1, piston 2, connecting rod 3 and crankshaft 4; In casing 1, connecting rod 3 two ends are connected with piston 2 and crankshaft 4 respectively; This device has inherent The shortcoming is that the connecting rod 3 in the reciprocating rocking motion inevitably produces a lateral force on the piston 2, and causes the piston group to do lateral translation and rotational swing in the cylinder, wherein the lateral force finally acts on the cylinder through the piston wall. It is this lateral force and the lateral translation and rotation...
