Embodiment 1

[0029] like Figure 1-2 As shown, the shaft system frequency regulator provided in this embodiment includes a casing 1, an inertia ring 2, a positioning pin 3, an elastic member 4 and a cover plate 5; There is an annular mounting groove for accommodating the inertia ring 2 ; specifically, a mounting hole for mounting the crankshaft is provided in the center of the housing 1 . The inertia ring 2 is arranged in the annular installation groove, and can slide relatively along the annular installation groove; one end of the positioning pin 3 is connected with the outer side of the inertia ring 2 through the elastic member 4, and the inner wall of the annular installation groove is provided with a positioning pin 3 to insert the pin hole, the cover plate 5 is encapsulated above the annular mounting groove. The shafting frequency modulator can replace the shock absorber to reduce vibration, so that when the engine works at a lower speed, the shafting frequency is higher, and the res...

Abstract

The invention relates to the technical field of engines, in particular to a shafting frequency modulator and an engine. The shafting frequency modulator comprises a housing, an inertial ring, a location pin, an elastic part and a cover plate, wherein the housing is mounted at the front end of a crankshaft; one side of the housing is provided with a ring-shaped mounting slot for accommodating the inertial ring; the inertial ring is arranged in the ring-shaped mounting slot, and is capable of generating relative sliding along the ring-shaped mounting slot; one end of the location pin is connected to the outer side of the inertial ring through the elastic part; a pin hole for allowing the location pin to insert is formed in the inner wall of the ring-shaped mounting slot; and the cover plate is encapsulated above the ring-shaped mounting slot. The shafting frequency modulator can enable the engine to have relatively high shafting frequency during working at a relatively low rotation speed, and to have relatively low shafting frequency during working at a relatively high rotation speed, so that a resonant rotation speed is avoided, and therefore, torsion vibration of the engine is at relatively low level, and the purpose of reducing the shafting torsion vibration is realized.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a shaft frequency regulator and an engine. Background technique [0002] At present, the crankshaft is one of the main moving parts in the internal combustion engine. Its strength and reliability determine the reliability of the internal combustion engine to a large extent. It will generate torsional vibration during operation, and in the resonance state, torsional vibration shears The shear force is particularly large, and when the stress exceeds the stress that the shafting can bear, the shafting will break. At present, shock absorbers are generally used to reduce shafting torsional vibration. However, the manufacturing process of this structure is complicated, the cost is high, and there is also the problem of aging of the shock absorber silicone oil or rubber, and the working reliability is poor. SUMMARY OF THE INVENTION [0003] (1) Technical problems to be solved [00...
