Abstract
The invention relates to a crankshaft balancer used with an engine, which comprises a crankshaft, a fly wheel, a belt pulley and a balancing system. The fly wheel and the belt pulley are respectively connected with the crankshaft. The balancing system comprises balancing pieces directly arranged on the fly wheel and the belt pulley. Since the fly wheel and the belt pulley are respectively provided with a balancing piece, the individual parts (such as the fly wheel, the crankshaft and the belt pulley) are unbalanced, but the whole crankshaft system is balanced well. The invention solves the technical problems that the crankshaft weight and balancer are limited by the inner space of the crankshaft case.
Description
Technical field
The present invention relates to motor, be specifically related to crankshaft counterbalance mechanism on the motor.
Background technique
Engine luggine, noise directly influence the travelling comfort of car load and the structural strength of motor itself, vibrate working life and performance that senior general causes correlated parts.General engine interior vibration reaches the balance of crankshaft system by the reasonable Arrangement of crankshaft counter balance, the crank throw of multi-cylinder engine has is space distribution, what have is plane distribution, and in general 6 cylinder machine crankshafts can be accomplished absolute equilibrium, and other cylinders are counted type and are difficult to accomplish complete equilibrium.Owing to the disequilibrium of crankshaft system, can cause vibration, the noise of motor, will cause when serious that part destroys; More steady and guarantee personnel's travelling comfort by bus for engine operation, adopt the reasonable Arrangement equilibrium block usually, increase modes such as trunnion shaft and realize.But following problem can occur like this: the increase of equilibrium block can increase the weight of whole bent axle, thereby increases cost; The size of equilibrium block is subjected to the restriction of crankcase inner space; The shaped design of equilibrium block is subjected to the influence of manufacturing process.
Summary of the invention
The invention provides a kind of crankshaft counterbalance mechanism, with the weight of the bent axle that solves existing crankshaft counterbalance mechanism, equilibrium block is subjected to the technical problem of the restriction of crankcase inner space.
In order to solve above technical problem, the technological scheme that the present invention takes is: a kind of crankshaft counterbalance mechanism, comprise bent axle, flywheel, belt pulley and balance sysmte, flywheel is connected with bent axle respectively with belt pulley, it is characterized in that described balance sysmte includes the counterbalance that is set directly on flywheel and the belt pulley.
Described counterbalance is the material block that increases the weight of.
Described counterbalance is the groove or the emptying aperture of loss of weight.
Described balance sysmte also comprises the equilibrium block that is set directly on the bent axle.
After having adopted technique scheme, owing on the flywheel belt pulley, increased counterbalance respectively, itself be unbalanced for single part such as flywheel, bent axle and crank pulley like this, but can reach good balance whole crankshaft system.This is because rotatory inertia moment T=m*r, it is the product that running torque equals gyrating mass and turning radius, therefore the present invention's design certain position on the flywheel of crankshaft system increases or the removal material, because flywheel diameter is very big, therefore this go material with respect to the position of crankshaft center line can do very big, promptly turning radius r can be very big, therefore will reach identical running torque T, gyrating mass m can be relative diminish, but the whole trimming moment that is produced can remain unchanged.In addition, the present invention can also reduce total quality of crankshaft system, reduces cost; It is block-shaped to simplify crankshaft counterbalance, reduces equilibrium block quantity and dwindles the equilibrium block radius, thereby can improve the bent axle manufacturability; Make whole crankshaft counterbalance system architecture simple, compact, under same case, can improve the balanced ratio of crankshaft system.
Description of drawings:
Fig. 1 is a perspective view of the present invention.
Embodiment
As shown in Figure 1, a kind of crankshaft counterbalance mechanism, comprise bent axle 2, flywheel 1, belt pulley 3 and balance sysmte, flywheel 1 is connected with bent axle 2 respectively with belt pulley 3, balance sysmte comprises counterbalance 4 that is arranged on flywheel 1 and the belt pulley 3 and the equilibrium block 5 that is arranged on the bent axle, counterbalance 4 is the groove or the emptying aperture of loss of weight, forms by remove material on flywheel and belt pulley; Certainly, counterbalance 4 also can be the material block that increases the weight of, and forms by increase material on flywheel and belt pulley.
Claims (4)
1. a crankshaft counterbalance mechanism comprises bent axle, flywheel, belt pulley and balance sysmte, and flywheel is connected with bent axle respectively with belt pulley, it is characterized in that, described balance sysmte includes the counterbalance that is set directly on flywheel and the belt pulley.
2. crankshaft counterbalance as claimed in claim 1 mechanism is characterized in that described counterbalance is the material block that increases the weight of.
3. crankshaft counterbalance as claimed in claim 1 mechanism is characterized in that described counterbalance is the groove or the emptying aperture of loss of weight.
