Embodiment 1

[0051] The shell diameter of the shock absorber based on the polyurethane filler of the present embodiment is 213mm, and the shell height is 105mm, wherein, the mass ratio range of the polyurethane particles and the filler in the elastic particles is 8:2-9:1, different types of shock absorbers The load bearing capacity of the device is different from the yield force. The load range is 1000KG-1350KG, the maximum load is 1550KG, the yield force range is 2.3KN-6.6KN, the linearity after yielding is good, and the stiffness range is 0.53KN / mm- 0.82KN / mm.

[0052] Production Method:

[0053] Put a certain amount of elastic granules into the net bag, tie them up and weigh them without leakage, place them in the shell, and assemble them on the special fixture. The order from top to bottom is fixed ring, backing plate, rubber pad, and elastic granules. and casing.

[0054] Carry out its force and displacement test, determine its yield force, stiffness, and whether the linearity after...

Abstract

The invention discloses a vibration absorber based on polyurethane filler. The vibration absorber comprises a barrel-shaped outer shell, a base plate and elastic particles, wherein the elastic particles include polyurethane particles, the elastic particles are arranged in the outer shell, and the base plate is arranged between the elastic particles and the opening of the outer shell. The vibration absorber based on the polyurethane filler is simple in structure, due to the fact that the outer shell of the vibration absorber is filled with elastic materials with the polyurethane particles, the defects that various forming motions of a system are interfered with and damaged due to vibration produced in the production conducted through thread spanner machines, production efficiency is improved, and the service life of the machines is prolonged.

Description

technical field [0001] The invention belongs to the field of vibration and noise reduction of industrial equipment, and in particular relates to a shock absorber based on polyurethane filler. Background technique [0002] The rapid development of high-speed and high-power mechanical equipment has brought about serious problems such as vibration and noise. Long-term use will cause failure of some components, instrumentation failure, and shortened life. In severe cases, it may even affect the accuracy and efficiency of mechanical equipment and reduce the performance of equipment. And reliability, thus causing disastrous consequences, affecting production and causing extremely heavy economic losses. Elastic damping materials and technology are the most effective methods to control structural resonance, structural vibration and noise. It has not only become a research field that is highly valued internationally, but also has achieved many successful applications in the industry ...
