Abstract
The utility model provides a self-lubricating two-level balancing device for four-cylinder diesel engine, which is characterized in that a balancing frame is mounted at bottom of the engine; the balancing frame has a left balancing shaft and a right balancing shaft which are engaged into each other and rotates symmetrically and have semi-circular balancing weights, inner end of the right balancing shaft having shaft-end gears; the balancing frame also has a main shaft, outer end of which are provided with outer-end gears and inner end of which are provided with inner-end gears engaging into shaft-end gears of the right balancing shaft; lateral surface of the balancing frame is provided with idle gears which engage into outer-end gears of the main shaft for transmitting the engine power. The left and right balancing shafts produce a balancing force which cancels the reciprocating inertia force of the cylinder, thereby greatly reducing the vibration noise of the engine and improves the performance and useful life thereof. The utility model, besides, has the advantages of compact structure, small size and low power loss etc.
Description
Technical field
The utility model relates to a kind of motor damping Equilibrator that is used for, especially a kind of four-cylinder diesel engine selflubricating secondary Equilibrator.
Background technique
The secondary Equilibrator is mainly used in the secondary reciprocal inertia force in the balance four cylinder engine, and this advocates to comprise the inertial force and the cylinder gas force of four cylinder engine crank mechanism, and these power all have strong impact and the effect of wide band exciting.The vibration of motor and the noise that causes thus not only influence working environment but also may cause the resonance response of oil pipe, water pipe, tracheae and various accessory on the motor, cover plate, case etc., and motor is damaged.At present the Vibration damping balance method of state's intrinsic motivation is that other direction at crank lays counterweight block, and the centrifugal inertia force that makes it to produce just in time equals original centrifugal inertia force, thereby averages out; The vibration force of cylinder gas then can't be eliminated, so vibration and noise reducing efficient is low.
Summary of the invention
The utility model provides a kind of effect of vibration and noise reduction good four-cylinder diesel engine selflubricating secondary Equilibrator for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Four-cylinder diesel engine selflubricating secondary Equilibrator, by the equalization frame that is connected with the motor bottom, parallel left trunnion shaft and the right trunnion shaft that gear pair is meshed that pass through that is installed in the equalization frame, be shaped on semicircle equilibrium block on left side trunnion shaft and the right trunnion shaft, and the gear drive that drives left trunnion shaft and the rotation of right trunnion shaft is formed, it is characterized in that: described gear drive is that the main shaft that two ends are equipped with outer end gear and inner gear respectively is installed in equalization frame, be shaped on the shaft end gear that is meshed with the inner gear of main shaft at right trunnion shaft one end, in the equalization frame outside idle pulley that is meshed with main shaft outer end gear is installed also, the oil pump to the defeated lubricant oil of motor confession by main shaft drives also is installed in equalization frame.
Advantage and the good effect that the utlity model has are: owing in the motor bottom equalization frame is installed, the left trunnion shaft that has semicircle equilibrium block and the right trunnion shaft that are meshed and rotate on the contrary by gear pair are installed in equalization frame, the gear drive of the engine crank transmission of power being given left and right sides trunnion shaft also is installed in equalization frame, make a left side, the power that right trunnion shaft produces is offset the secondary reciprocal inertia force of motor, greatly reduce the vibrating noise of motor, the performance and the working life of motor have been improved, the oil pump to the defeated lubricant oil of motor confession that is driven by main shaft has been installed in equalization frame in addition, simplify the structure, the utility model also has compact structure, size is little, reduce the advantage of power loss.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode figure;
Fig. 3 is the schematic representation of right trunnion shaft 10 among Fig. 1.
Among the figure: 1-equalization frame, 2-main shaft, 3-outer end gear, 4-idle pulley, 5-oil pump, the inner gear of 6-, the semicircle equilibrium block of 7-, 8-gear, 9-left side trunnion shaft, the right trunnion shaft of 10-, 11-gear, the semicircle equilibrium block of 12-, 13-shaft end gear, 14-crankshaft gear, 15-bent axle, 16-motor.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, equalization frame 1 is rectangular.Be symmetrically installed with left trunnion shaft 9 and right trunnion shaft 10 in equalization frame one side, the gear 8,11 that symmetry is shaped on semicircle equilibrium block 7,12 and is meshed on left trunnion shaft and right trunnion shaft, as shown in Figure 3, the inner of right trunnion shaft also is shaped on shaft end gear 13.The main shaft 2 of transferring power is installed at the equalization frame opposite side, the outer end of main shaft is equipped with outer end gear 3, the inner of main shaft is equipped with the inner gear 6 that is meshed with the shaft end gear of right trunnion shaft, at the equalization frame outer side surface idle pulley 4 with main shaft outer end gear engagement is installed, idle pulley is mainly used in the power that transmits motor.The oil pump 5 to the defeated lubricant oil of motor confession that is driven by main shaft also is installed in equalization frame, makes the overall structure of motor compact more like this.
Working principle of the present utility model is:
As shown in Figure 2, the utility model is installed on the bottom of motor 16, makes the crankshaft gear 14 picture engagements of idle pulley 4 of the present utility model and engine crank 15.When engine start, crank drives crankshaft gear and rotates, crankshaft gear drive idle pulley 4, main shaft outer end gear 3, main shaft 2, the inner gear 6 of main shaft, the shaft end gear 13 of right trunnion shaft, right trunnion shaft 10, gear 11, gear 8, left trunnion shaft 9 rotate together, thereby two semicircle equilibrium block symmetries that drive on left trunnion shaft and the right trunnion shaft are rotated, produce a counteracting engine luggine equilibrant, the cylinder reciprocal inertia force of this power and motor offsets.
