Problems solved by technology

[0002] The existing shock absorption technology generally uses a stainless steel straight shaft to directly connect the rotating assembly for centrifugal separation. Because the stainless steel shaft is too rigid, the rotating torque generated by the rotor at high speed may cause the stainless steel straight shaft to break. has a certain risk

Embodiment

[0015] A flexible shock-absorbing shaft with a structure such as figure 1 As shown, the shock-absorbing shaft is composed of a rotating shaft 1, a compression nut 2, an elastic washer 3, an elastic shock-absorbing sleeve 4, and an elastic shaft head 5. The front end of the rotating shaft 1 is connected with the elastic shock-absorbing sleeve 4 via a compression nut 2, The shape of the elastic shock-absorbing sleeve 4 is a plum blossom shape, the elastic washer 3 is cushioned between the compression nut 2 and the elastic shock-absorbing sleeve 4, the rear of the elastic shaft head 5 is provided with a slot, and the plum blossom-shaped elastic shock-absorbing sleeve 4 It is locked in the slot, and the swing amplitude of the elastic shaft head 5 is 5 mm. The invention is applied to the flexible damping shaft of the LXJ-IIB type low-speed large-capacity multi-tube centrifuge. The rotor is a hexagonal stainless steel horizontal rotor casting. The weight is 10kg, the full load is abo...

Abstract

The invention relates to a flexible shock absorber shaft, which comprises a spindle, a gland nut, an elastic gasket, an elastic shock absorber cover and an elastic shaft head, wherein the front end of the spindle is connected with the elastic shock absorber cover through the gland nut, an elastic gasket is arranged between the gland nut and the elastic shock absorber cover, and the elastic shaft head is sleeved outside the elastic shock absorber cover. Compared with the prior art, the flexible shock absorber shaft has better shock absorber effect, can not cause that the spindle is rigidly broken, can better reach a balance point through rotation when a rotor with larger unbalance quantity is positioned on a rotating head so that shock is reduced, and stably raises and operates.

Description

Technical field [0001] The invention relates to a shock absorption device, in particular to a flexible shock absorption shaft. Background technique [0002] The existing shock absorption technology generally uses a stainless steel straight shaft to directly connect the rotating components for centrifugal separation. Because the stainless steel shaft is too rigid, the rotating torque generated by the rotor at high speed may cause the stainless steel shaft to break. There is a certain degree of danger. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a flexible damping shaft with excellent damping effect and quicker balance point. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A flexible shock-absorbing shaft, characterized in that the shock-absorbing shaft is composed of a rotating shaft, a compression nut, an elastic washer,...
