Abstract
The utility model discloses a single-shaft balancing mechanism for single-cylinder four stroke petrol engine. The technical proposal is that: a balance shaft is arranged between the left and the right crankcase, the balance blocker is arranged at the center part of the balance axle, and the balance blocker is symmetric with the middle line of cylinder at the left and right sides; a gear is arranged on the balance axle, the gear is connected with the balance shaft through the semi-circular key, another gear drive is arranged on the crank axle; then the balance shaft drive gear on the crank shaft is arranged on the right crank shaft of engine and between the crank shaft bearing and the right crank shaft arm. The utility model has the advantages of simple and reliable structure, rational design, obvious damping effects, low production costs, and stable product quality, etc.
Description
Technical field
The utility model relates to a kind of mini four-stroke gasoline engine, in particular, relates to the uniaxiality balance mechanism that is used for the single-cylinder four-stroke petrol engine that a kind of motorcycle uses.
Background technique
Existing mini four-stroke motor all adopts the excessive balance method, promptly do not adopt trunnion shaft, but utilize the unnecessary balancer weight of a part to come the partial equilibrium reciprocal inertia force, its objective is that to make structure simple as far as possible, but excessive balance method essence is the transfer of one order inertia power, promptly the part of one order inertia power is transferred in the vertical plane of direction with it, its counterbalance effect is not as single shaft and double-shaft balance mechanism.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and reasonable, the uniaxiality balance mechanism that is used for the single-cylinder four-stroke petrol engine of good balance effect.
The utility model is used for the uniaxiality balance mechanism of single-cylinder four-stroke petrol engine, comprise left and right sides crankcase, bent axle, the right crank of bent axle, described bent axle is between the crankcase of the left and right sides, the right crank of described bent axle be on the bent axle between bent axle right bearing and crankshaft-link rod, a trunnion shaft is installed between the crankcase of the described left and right sides, described trunnion shaft middle part is provided with equilibrium block, described equilibrium block is with respect to the cylinder centerline bilateral symmetry, described trunnion shaft is provided with a gear, described gear links to each other with trunnion shaft by woodruff key, by another gear drive that is arranged on the bent axle, trunnion shaft actuation gear on the described bent axle is arranged on the right crank of motor, and places between crankshaft bearing and the right crankweb.
Described equilibrium block is semicircle.Described trunnion shaft relative equilibrium piece one side is provided with groove.
The utility model beneficial effect compared with prior art is, in the engine working process, trunnion shaft can fall the single order reciprocal inertia force complete equilibrium that piston, connection rod set produce, therefore the vibration and the noise of motor have obviously been reduced, help improving the moment of torsion output of motor, and improve power.The utlity model has simple and reliable for structurely, reasonable in design, effectiveness in vibration suppression is obvious, and cost of production is low, characteristics such as constant product quality.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Comprise left crankcase 1, right crankcase 2, bent axle 3, the right crank 4 of bent axle, described bent axle 3 is between left crankcase 1 and right crankcase 2, the right crank 4 of bent axle is the part between bent axle right bearing 5 and crankshaft-link rod 6 on the bent axle, a trunnion shaft 7 is installed between left crankcase 1 and the right crankcase 2,7 ones of trunnion shafves are provided with equilibrium block 8, equilibrium block 8 is with respect to the cylinder centerline bilateral symmetry, and equilibrium block is semicircle.Trunnion shaft relative equilibrium piece one side is provided with groove 9.Trunnion shaft 7 is provided with a gear 10, gear 10 links to each other with trunnion shaft by woodruff key, driven by another gear 11 that is arranged on the bent axle, the trunnion shaft actuation gear 11 on the described bent axle is arranged on the right crank 4 of bent axle, and places between crankshaft bearing and the right crankweb.
