Embodiment 1

[0025] like Figure 1-4 , a reversible coupling, including a splined shaft 1, an inner disc 2, a side plate 3, a coupling flange 4, a cover plate 6 and a sealing ring seat 5. Spline teeth 14 are arranged on the spline shaft 1, a through groove is arranged on the inner disk 2, and a group of reeds 13 are arranged on the through groove, and the inner disk 2 is sleeved on the spline shaft 1. In the spline tooth part, two sets of reeds 13 are located in a tooth groove of the spline tooth 14, and the coupling flange 4 is arranged at the outermost end of the spline shaft 1 and is fitted and fixed with one end surface of the inner disc 2 , the side plate 3 is arranged on the other end face of the inner disc 2 . A pin hole 12 is also arranged on the inner disc 2 , and the reed 13 is fixed on the inner disc 2 by driving a pin into the pin hole 12 . The spline shaft 1 has an oil inlet hole towards A and an oil return hole towards B, and the cover plate 6 has grooves to ensure that the...

Abstract

The invention discloses a reversible rotation coupling. The reversible rotation coupling comprises a spline shaft, an inner disk, a side plate and a coupling flange, spline teeth are arranged on the spline shaft, through grooves and an oil cavity are formed in the inner disk, a set of reeds is arranged in each through groove, the inner disk is connected to the spline tooth part of the spline shaftin a sleeving mode, the two sets of reeds are located in one teeth groove of the spline teeth, oil is arranged in the space of the oil cavity, the coupling flange is arranged at the outermost end ofthe spline shaft and attached and fixed to one end face of the inner disk, and the side plate is connected with the other end face of the inner disk. During working, torsion vibration causes the deformation of the reeds, because the reeds have the damping effect when located in the oil, the partial torsion vibration is absorbed by damping, and the torsion vibration is reduced.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a reversible shaft coupling. Background technique [0002] With the continuous development of diesel engine design, the problem of torsional vibration of diesel engine power plant has attracted more and more attention. Torsional vibration is a special form of mechanical vibration that commonly exists in various rotating machinery, such as steam turbines, gas turbines, fans, automobile drive shafts, generators, engine crankshafts, compressors, etc. The reason for this is that the rotor is not an absolute rigid body in practice, but is elastic. Therefore, during the rotation process, different parts of the same shaft will have different instantaneous speeds, and torsional deformation will occur between the elastic parts. , which is the torsional vibration of the shafting. [0003] If the torsional vibration amplitude of the shaft system is too large and the deformation exceeds the elastic limi...
