Abstract
The invention discloses a balance mechanism of a single cylinder diesel. The balance mechanism is arranged at the rear end of an engine body of the diesel and comprises a shell, wherein the shell is internally provided with an upper balance shaft and a lower balance shaft which are parallelly arranged, the end part, which stretches out of the shell, of the upper balance shaft is provided with an upper balance shaft gear, the end part, which stretches out of the shell, of the lower balance shaft is provided with a lower balance shaft gear which is meshed with the upper balance shaft gear, the upper balance shaft at the outer side of the upper balance shaft gear is provided with a driving gear which drives the upper balance shaft to rotate as the driving gear is in mesh transmission with a crankshaft gear of the diesel, and the shell is provided with a lubricating oil duct which is used for leading lubricating oil into the shell. The balance mechanism disclosed by the invention is different from a balance method of a common single cylinder diesel, a modularized design is adopted, a unit body is independently formed by two balance shafts which are originally arranged in the engine body of the diesel, the unit body is arranged at the rear end of the engine body of the diesel in an assembly way, due to the balance shaft installation form, the assembling and the disassembling are simple and convenient, the whole size of the engine body of the diesel can be reduced, and the structure of the engine body is more compact.
Description
Technical field
The present invention relates to the single cylinder diesel technical field, especially a kind of single cylinder diesel balanced controls.
Background technique
Balanced controls are very crucial parts in diesel engine, design the unreasonable diesel engine that will cause and produce larger vibration when work, cause the loosening or overload of link, reduce stability and the utilization efficiency of diesel engine work, the balance of single cylinder diesel, generally adopt single shaft or double-shaft balance method more at present.
Monopodium balance mechanism is to arrange equilibrium block except the end at crankweb, also by crankshaft gear, drive another root trunnion shaft, the rotating speed of trunnion shaft equates and opposite direction with speed of crankshaft, also arranged an equilibrium block on trunnion shaft, two potential of centrifugal force the making a concerted effort on the cylinder centerline parallel direction that equilibrium block produces, the opposite directions with the reciprocal inertia force equal and opposite in direction all the time.The shortcoming of this balanced controls is: two equilibrant are asymmetric with cylinder centerline, so it makes a concerted effort to form unbalance moment with reciprocal inertia force.
Dual-shaft balance mechanism, two trunnion shafves are driven by sloth wheel gear by crankshaft gear, the rotating speed of diaxon equates and opposite direction with speed of crankshaft, respectively be furnished with equilibrium block on two axles, the component of its centrifugal force on the cylinder centerline direction equals 1/2nd of reciprocal inertia force, because the position of two trunnion shafves is symmetrical in cylinder centerline, make a concerted effort all the time with the equal and opposite in direction of the reciprocal inertia force opposite direction of two centrifugal force on cylinder centerline while therefore working, can not produce unbalance moment, thereby obtain good effect.The shortcoming of this method is that structure is comparatively complicated, and part increases more, and the mounting point of twin shaft is all in body, and body makes the animal economy size lengthen for reserving the trunnion shaft mounting point, causes rigidity variation and weight increase.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of compact structure is provided, installs and removes single cylinder diesel balanced controls convenient, that adopt integrated type to install.
The technical solution adopted for the present invention to solve the technical problems is: a kind of single cylinder diesel balanced controls, integral installation is in the rear end of diesel engine, comprise housing, be provided with the upper trunnion shaft and the lower trunnion shaft that are arranged in parallel in housing, described upper trunnion shaft stretches out the outer end of housing balance shaft gear is installed, lower trunnion shaft stretches out the outer end of housing and is equipped with and the intermeshing lower balance shaft gear of upper balance shaft gear, the upper trunnion shaft in the upper balance shaft gear outside is provided with and drives the actuation gear that upper trunnion shaft rotates with the diesel engine crankshaft gear engagement driving, offer on housing lubricant oil is introduced to the oil leab in housing.
Be separately installed with upper bearing bracket and step on described housing, upper trunnion shaft one end is supported in upper bearing bracket, the upper trunnion shaft the other end is supported in the supported hole that housing has and stretches out outside housing, lower trunnion shaft one end is supported in step, and the lower trunnion shaft the other end is supported in the supported hole that housing has and stretches out outside housing.
The flange periphery of described housing offers ten bolts hole for housing is connected with diesel-engine body.
The invention has the beneficial effects as follows: the present invention is different from common single cylinder diesel machine balance method, adopt modular design, two trunnion shafves that originally are arranged in diesel-engine body are consisted of separately to a cell cube, be arranged on the body rear end of diesel engine in the assembly mode, such trunnion shaft installation form, mount and dismount simple and conveniently, and can reduce the overall dimensions of diesel-engine body, make housing construction more compact.

Embodiment
With preferred embodiment, the present invention is further illustrated by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As Fig. 1, a kind of single cylinder diesel balanced controls shown in Fig. 2, adopt modular design, be arranged on the body rear end of diesel engine, comprise housing 1, be provided with the upper trunnion shaft 2 and the lower trunnion shaft 3 that are arranged in parallel in housing 1, housing 1 rear end is separately installed with upper bearing bracket 8 and step 9, housing 1 front end has supported hole, upper trunnion shaft 2 one ends are supported in upper bearing bracket 8, upper trunnion shaft 2 the other ends are supported in the supported hole that housing 1 has and stretch out outside housing 1, lower trunnion shaft 3 one ends are supported in step 9, lower trunnion shaft 3 the other ends are supported in the supported hole that housing 1 has and stretch out outside housing 1.
The shaft end stretched out outside housing 1 at upper trunnion shaft 2 is equipped with balance shaft gear 4 and actuation gear 6 successively, lower trunnion shaft 3 stretches out housing 1 outer end lower balance shaft gear 5 is installed, upper balance shaft gear 4 and the intermeshing transmission of lower balance shaft gear 5, actuation gear 6 drives upper trunnion shaft 4 by an idle pulley and diesel engine crankshaft gear engagement driving and rotates, and realizes the transmission of moment.
