The engine is characterized in that a balance institution is arranged in the body (2), the two balance axes (4), (6 )which are in the balanced institution and the crankshaft (1) are paralleled, and symmetrically installed under the crankshaft (1) or on the above of the body (2), the balanced axes (4), (6) are provided with a balanced weight block (5), and an inter-gear transmission is arranged between the balanced axes (4), (6) and crank (1).
Description
Technical field
The utility model relates to the vertical air-cooled diesel engine of a kind of double-shaft balance formula single cylinder, belongs to the internal-combustion piston engine technical field.
Background technique
At present, existing upright single cylinder air-cooled diesel engine, the balance shock mechanism of its reciprocal inertia force is too simple, and over-borrowing helps crankshaft counterbalance pouring weight and flywheel balancing pouring weight etc. and reaches and alleviate the purpose that machine shakes.Its advantage is simple in structure, low cost of manufacture.Its deficiency is that effectiveness in vibration suppression is poor, and diesel vibration is more serious, and the additional load of bearing is bigger, and parts are fragile.Especially high-power single cylinder engine, its vibration is more serious.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of double-shaft balance formula single-cylinder air-cooled diesel engine, and this machine balance quality is good, and machine shakes and obviously alleviates.
It is as follows to address the above problem the technological scheme that is adopted:
The vertical air-cooled diesel engine of a kind of double-shaft balance formula single cylinder, it comprises connecting rod and body, be provided with balanced controls in the said body, two trunnion shafves of balanced controls are parallel with the bent axle of connecting rod, and symmetry is installed on the body of bent axle below or top, trunnion shaft is provided with counterweight block, is provided with the timing gear transmission device between trunnion shaft and bent axle.
The vertical air-cooled diesel engine of above-mentioned double-shaft balance formula single cylinder, said timing gear transmission device are that crankshaft gear is meshed with balance shaft gear respectively through two intermediate gears, and crankshaft gear equates with the number of teeth of balance shaft gear.
The above-mentioned vertical air-cooled diesel engine of double-shaft balance formula single cylinder, it is that trunnion shaft is installed on the body through rolling bearing that said trunnion shaft is installed on the body.
The balance method of the vertical air-cooled diesel engine of double-shaft balance formula single cylinder provided by the utility model adopts the double-shaft balance method, and its working principle is to come balance rotating inertial force with the counterweight block on the bent axle.Counterweight block on two trunnion shafves is used for the balance reciprocal inertia force.Its good effect is that balance quality is good, the vibration that the energy significant effective alleviates diesel engine, and bent axle operates steadily, and bearing and associated components prolong working life.This diesel engine is comparatively ideal auxiliary power equipments such as tractor, generator, water pump.

Embodiment
The utility model is described in further detail below in conjunction with embodiment's accompanying drawing:
Referring to accompanying drawing, the vertical air-cooled diesel engine of double-shaft balance formula single cylinder provided by the utility model is the improvement on former diesel engine basis, adopts the twin axle balanced controls to replace original better simply balanced controls, alleviates the purpose that machine shakes to reach.9,10 of two trunnion shafves 4,6 and balance shaft gears can adopt key connecting to fix respectively.Trunnion shaft 4,6 is installed on the body 2 through rolling bearing 3.It is indoor that crankshaft gear 7, intermediate gear 8,11 and balance shaft gear 9,10 are arranged in the timing gear of diesel engine.For guaranteeing that trunnion shaft 4,6 is identical with the rotating speed of bent axle 1, then the number of teeth of gear 7,9,10 must equate.In addition, following condition should be satisfied in the mounting point of the counterweight block 5 on the trunnion shaft 4,6, and promptly when the piston of diesel engine is in top dead center, equilibrium block should be in below, as shown in Figure 1, so that make the centrifugal force of counterweight block generation and the reciprocal inertia force balance of connecting rod.Two trunnion shafves 4,6 can symmetry be installed on the body 2 of bent axle 1 below.In order to reduce the complete machine height, two trunnion shafves 4,6 also can symmetry be installed on the body 2 of bent axle 1 top.
Claims (3)
