Flexible torsional couplings are used primarily to transmit power between rotating components in industrial power systems including turbomachinery while allowing for small amounts of misalignment that may otherwise lead to equipment failure The torsional coupling lumped characteristics such as torsional and flexural stiffness as well as natural frequencies
Accurately predicting the nonlinear dynamic response of shaft disk rotors is crucial in the design of rotary machines In available studies the disk is commonly treated as rigid body to simplify the analysis of the nonlinear problem This paper aims to clarify the effect of disk flexibility on the nonlinear dynamic response of shaft disk rotors Both gyroscopic and
Many researchers have contributed to the literature on the stiffness and corresponding dynamic behavior of flexible couplings Ma and Han [7] established non linear motion equations for a rotating system coupled by flexible coupling and examined the effect of impact moment on the non linear stiffness of flexible coupling Chakrabarti [8] used a modified
The disk crusher includes a crushing chamber 1 on which a fixed disk 2 with a bunker 3 is fixed on top On a fixed disk there are counter ribs 4 and partitions 5 At the beginning of each edge is connected by partition 1 to the end of the adjacent edge 4 forming a zigzag closed contour of protruding ribs and partitions between them
This paper improved and developed Shaft disk blade SDB rotor system based on the previous studies of the authors in the last decade from Yang and Huang 2005 to Chiu et al 2017 This paper also explored blade bending disk transverse and shaft torsion coupling vibration of a multi flexible disk rotor system Unlike the previous studies of the authors this
The idea of a flexible disk rotating in a close proximity of a rigid rotating wall is introduced and studied with two new types of flat stabilizers co rotating and counter rotating flat stabilizers besides the well known fixed stabilizer type which has been studied extensively in earlier works In the present study the flexible disk is

Abstract This study focuses on the coupling vibration of a rotating flexible disk drum structure with a non continuous connection and investigates the frequencies and mode shapes of the coupled system The Sanders shell and the Kirchhoff plate
The flexible disk rotor system was divided into three modes of coupled vibrations Shaft disk blade disk blade and blade blade Two new modes of coupled vibrations were introduced namely
Flexible and adaptable Owing to its low torsional rigidity and damping properties the ELPEX S® coupling is very well suited to connecting machines with considerably non uniform torque characteristics The inside diameter of the rubber disk element is vulcanized on a flange
The utility model is to realize by following technical scheme a kind of crusher rotor comprises main shaft is arranged on the multiple parallel rotor disk on main shaft and be arranged on the weight head between adjacent two rotor disks; Also comprise at least one locating shaft; On described multiple rotor disk be respectively equipped with at least one locating hole;
Flexible couplings are often used to drive pumps fans compressors motor generator sets conveyors crushers vibrating screens etc Because a flexible coupling joins two machines / equipment it may be viewed with some lack of concern However in fact it can be a major contributor to performance problems of
