Summary of the invention
The purpose of this utility model is to provide a kind of single cylinder diesel that reduces vibration.
The utility model provides the single cylinder diesel of low vibration, and it comprises bent axle, connecting rod, camshaft and body; Bent axle comprises a rod journal and is arranged at respectively the crank at rod journal two ends; Connecting rod comprises a connecting rod shank and a connecting rod cap, and connecting rod cap is connected with the connnecting rod big end of connecting rod, so that connecting rod is installed on to rod journal; Each crank comprises a bent axle body, a counter weight and a pair of balancing bolt, and balancing bolt is fixed on bent axle body by counter weight; The connecting rod small end of connecting rod shank comprises a pair of microcephaly's deweighting block, and connecting rod cap comprises a major part deweighting block.
In another schematic mode of execution of the single cylinder diesel of low vibration, also comprise a catch, catch is fixed on body by fixing bolt, controls the speed regulation gear that is arranged on camshaft and the gap of body.In another kind of exemplary embodiment, the gap of body and speed regulation gear is 0.1 to 0.3mm.
Adopt the single cylinder diesel of low vibration of the present utility model, by the adjustment to quality after bent axle, Machining of Connecting Rod, and the axial clearance of camshaft and speed regulation gear is controlled, effectively reduced vibration and the noise of diesel engine, improved the reliability of complete machine.Realized the balance of rotary centrifugal force, reciprocal inertia force in the balance sysmte of single cylinder diesel.

Embodiment
For technical characteristics, object and the effect of invention are had more clearly and are understood, now contrast accompanying drawing embodiment of the present utility model is described, accompanying drawing is only for helping to understand the utility model, the not practical structures of representative products and true ratio, in each figure, identical label represents identical part.
In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the mode of execution that are described in this article " schematically " should be interpreted as a kind of preferred or have more the technological scheme of advantage.
In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".Except as otherwise noted, number range herein not only comprises the gamut in two end points, also comprises the some subranges that are contained in wherein.
As shown in Figure 1, the single cylinder diesel of low vibration it comprise bent axle 10, connecting rod 20, camshaft 30 and body 40.Bent axle 10 comprises a rod journal 12 and is arranged at respectively the crank 14 at rod journal 12 two ends.Connecting rod 20 comprises a connecting rod shank 24 and a connecting rod cap 22, and connecting rod cap is connected (referring to Fig. 3) with the connnecting rod big end of connecting rod 20, so that connecting rod 20 is installed on to rod journal 12.
Fig. 2 be II shown in Fig. 1 to schematic diagram.As shown in Figure 2, each crank 14 comprises a bent axle body 142, counter weight 144 and an a pair of balancing bolt 146, and balancing bolt 146 is fixed on bent axle body 142 by counter weight 144.
