Detailed Description
The utility model will now be described in detail with reference to the drawings and to specific embodiments.
As shown in fig. 1, a spring plate assembly for a hydraulic torsional damper includes an outer ring 101 and a plurality of limiting blocks 103 radially disposed in the outer ring 101, two spring plates 104 are sandwiched between every two adjacent limiting blocks 103, an intermediate spacer 102 is sandwiched between the two spring plates 104, one end of each spring plate 104 close to the outer ring 101 is clamped between the limiting block 103 close to the outer ring and one end of the other spring plate 104, one end of the spring plate 104 far away from the outer ring 101 is spaced from the other end of the limiting block 103 close to the outer ring by a gap, one end of the spring plate 104 is attached to the inner wall of the outer ring 101, and the other end is inserted into a groove on a shaft hub 2 of the hydraulic torsional damper.
The thickness of the spring plate 102 gradually decreases in the circumferential direction of the outer race 101 to the center of the circle.
The thickness of the limiting block 103 gradually decreases along the circumference of the outer ring 101 to the circle center direction.
A side washer 105 is arranged between the spring plate 102 and the outer collar 101.
Two spring plates 104 are located between the two limiting blocks 103, and a gap is arranged between one ends of the two spring plates 104, which are far away from the outer ferrule 101.
As shown in fig. 2 and 3, a hydraulic torsional damper comprises a spring plate assembly 1, a shaft hub 2 and two side plates 3, wherein the spring plate assembly 1 is arranged between the two side plates 3, two ends of the shaft hub 2 are respectively penetrated in the middle of the two side plates 3, the middle of the shaft hub 2 is penetrated through the spring plate assembly 1, and an inner cavity 4 for oil passing is formed among the spring plate assembly 1, the shaft hub 2 and the two side plates 3.
The spring plate 102 is connected to the side plate 3 by bolts.
The oil inlet 201 is arranged on the shaft hub 2, the oil outlet 301 is arranged on the side plate 3, and the oil inlet 201 and the oil outlet 301 are both communicated with the inner cavity 4.
When the oil pump is used, the crankshaft of the engine is fixedly connected with the shaft hub 2, the oil outlet on the crankshaft is communicated with the oil inlet 201, oil is injected into the inner cavity 4 from the oil inlet 201 by means of oil pressure of the crankshaft, and the oil returns to the engine from the oil outlet 301 after flowing through the inner cavity 4.
When the engine crankshaft rotates, the shaft hub 2 is driven to rotate, at the same time, the spring plate 104 generates bending deformation, namely, the shaft hub 2 and the side plate 3 synchronously move, and relative movement is generated among the shaft hub 2, the side plate 3 and the spring plate assembly 1, and the pressure difference caused by the relative movement is equivalent to hydraulic power reduction, so that a vibration reduction effect is generated. In the process, the spring plate can twist, so that the oil quantity at two sides of the spring plate is changed, and the resistance generated when the lubricating oil flows delays the relative movement generated among the shaft hub 2, the side plate 3 and the spring plate assembly 1, so that the torsional vibration is reduced, and the purpose of vibration reduction is realized.
In the utility model, the lubricating oil flows back and forth in the inner cavity, and hydraulic damping is generated.
The utility model reduces the surface temperature of the shock absorber by taking away the absorbed energy through the oil, and further prolongs the service life.
The service life of the silicon oil shock absorber can not meet the service life requirement of a specific high-horsepower diesel engine, and experiments prove that when the silicon oil shock absorber is used on the high-horsepower diesel engine, the service life of the silicon oil shock absorber is prolonged by 5 years or more than that of a conventional silicon oil shock absorber.
When the hydraulic torsional vibration damper is operated under the design working condition, the spring plate in the hydraulic torsional vibration damper is not required to be maintained on the premise of ensuring the high-pressure oil supply required by the hydraulic torsional vibration damper, and the service life of the damper is determined by the service life of the spring plate, so that the hydraulic torsional vibration damper is not required to be maintained.
The spring plate is made of an inlet 50CrVa material and is processed by machining, laser quenching, shot blasting and the like. The service life is ensured.
The above examples give detailed embodiments and specific operation procedures on the premise of the technical solution of the present utility model, but the scope of protection of the present utility model is not limited to the above examples.
