Embodiment

[0036] Such as Figure 1-Figure 4 Shown: the step-by-step torsion transmission and vibration absorption combined coupling, including the input half coupling 1, the sheath 2, the elastic sleeve 3, the middle section 4, the variable stiffness diaphragm group 5 and the output half coupling 6. The flange of the half-coupling 1 at the input end is connected with the sheath 2 through the elastic sleeve 3 to form an elastic torsion transmission and shock absorbing circuit. The outer teeth at the end of the half-coupling 1 at the input end cooperate with the inner teeth of the sheath 2 to form a strengthened torsion transmission circuit. The front end of the intermediate section 4 is connected with the sheath 2, and the rear end is connected with the output half-coupling 6 through the variable stiffness diaphragm group 5 to transmit the torque and further absorb the tip impact of the variable torque. The elastic sleeve 3 adopts a solid hollow structure design, and is provided with co...

Abstract

The invention provides an echeloned torsion transmission and shock absorbing combined coupling which comprises an input end half-coupling, a sheath, an elastic sleeve group, a middle joint, a variable-rigidity membrane group and an output end half-coupling. A flange of the input end half-coupling is connected with the sheath through the elastic sleeve group to form an elastic torsion transmission and impact absorbing loop. Outer teeth of the tail end of the input end half-coupling are matched with inner teeth of the sheath to form a torsion transmission strengthening loop. The front end of the middle joint is connected with the sheath, and the rear end of the middle joint is connected with the output end half-coupling through the variable-rigidity membrane group. By means of the echeloned torsion transmission and shock absorbing combined coupling, high-frequency torsion vibration of a diesel engine set, a reciprocating compressor unit and a frequency changer set can be effectively eliminated, and the problem that because the torsion is enlarged, connection and transmission of units become difficult in work of a chemical raw material gas compressor unit, an ethylene granulating machine group and the like is solved; and an optimal scheme is provided for long-distance transmission of a frequency-conversion renovation unit.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a stepwise torsion transmission and vibration absorption combined shaft coupling, which belongs to the technical field of connection and transmission of large rotating units. Background technique [0002] The frequency conversion transformation of motor-driven units is a key support project of the national energy conservation and emission reduction policy. Almost all qualified enterprises in cement, steel, and power plants are carrying out frequency conversion transformation of units. However, the working speed and torque of the frequency conversion unit are constantly changing, which will cause the unit to produce torsional impact, firstly cause vibration, and soon cause damage. ABB China Company found several instances where frequency conversion harmonics caused damage to main engine bearings. In addition, reciprocating compressor units, high-speed diesel units, chemical raw material gas co...
