Apr 09, 2014 The Hopf and double Hopf bifurcations analysis of asymmetrical rotating shafts with stretching nonlinearity are investigated. The shaft is simply supported and is composed of viscoelastic material. The rotary inertia and gyroscopic effect are considered, but, shear deformation is neglected. To consider the viscoelastic behavior of the shaft, the KelvinVoigt model is used.
A concentric-double-shaft simultaneously rotating apparatus in which a part of the force for driving an inner shaft to rotate is obtained by another device than a rotation controlled motor to thereby reduce the capacity of the rotation controlled motor to attain reduction in size of the apparatus, increase of stiffness, and so on. The concentric-double-shaft simultaneously rotating apparatus ...
A chair elbow capable of rotating with double shaft is disclosed. Two bearings are disposed on a mount board fixed on a chair. Each of the bearings connects one end of each of two rotating plates, while the other ends thereof are pivotally connected in a linear slot of a seat plate used for securing an armrest. The length of the slot is longer than the distance between the two bearings, and ...

Rotary shaft seals provide sealing and wiping functionality for rotating and swiveling movements under low pressure and high velocity. They perform two essential functions. The primary function is to retain the bearing or system lubricant in the system to avoid leakage. The secondary function of a rotary shaft seal is to preclude any contamination of the system by external particles or other ...
Alternatively, a shaft may simply connect to another shaft via a coupling. A shaft can be stationary and support a rotating member, such as the short shafts that support the nondriven wheels of automobiles often referred to as spindles. Some common shaft arrangements are illustrated in Figure 7.1.
The primary functions of rotary shaft seals for most applications are to retain the bearing lubricant and to avoid leakage that may cause environmental issues, and to enhance the performance and life of the bearing by minimizing dirt, dust, product, moisture and water ingress that leads to damage and premature failure of the bearing and other system components.

Protruding screws proved to be a problem because they could catch on a workmens clothing while rotating on a shaft, and pull them into the machinery. Shaft collars saw few improvements until the early 1900s when Howard T. Hallowell created the first recessed head socket set screw shaft collar.
2. Rotating element or moving part This casing is split along the horizontal centerline of the pump shaft, suction and discharge nozzles both being located in the lower half. With this arrangement, it is not necessary to disconnect suction or discharge piping to make repairs to, or replace the rotating element. Upper and lower half casings are
I built up a simple rotating shaft with two plastic disks at its base. One disk is physically attached to the base and the other rotates with the shaft. Here the transmitters coil is attached to the base that has the motor attached to it as well.
Double-lip PTFE rotary shaft seal The redundant seal lips enable this seal to handle higher pressure and create additional sealing capabilities, especially under flooded conditions. The soft OD eliminates damage to housings manufactured from expensive metals, and the integrated O-ring on the OD of the seal serves as an anti-rotation device and ...

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating. Low-Profile Support Rails At approximately one-third the height of standard versions, these rails provide linear shaft support in applications with low vertical clearance.
The Double Cardan joint output shaft will be rotating at the same speed as the input speed while the U-Joint output shaft will be moving at a varying speed. ... Repeat steps 10-11 to secure the Double Cardan shaft Insert the Pivot Base over the shafts of the U Joint shaft and the Double Cardan shaft
Shaft Seals A challenge finding the reliable seal solution for a rotating shaft. SEEPEX provides different shaft seal types and configurations from established seal manufacturers.
Consider a disturbing mass m1 which is attached to a shaft rotating at rads. Let 1 1 1 the centre of gravity of the mass m distance between the axis of rotation of the shaft and r radius of rotation of the mass m The centrifugal force exerted by mass m1 on the shaft is given by, c 1 1F m r 2
Raise your chalk near the drive shafts rear, using a stand for support. Raise it until you make contact with the rotating shaft. The mark shows the location of the shafts heavy spot. Step 6. Ask your assistant to step on the brakes gently, then turn the engine off. Step 7.
The shaft seal is a sealing element which seals the rotating shaft of a centrifugal pump where it passes through the non-rotating pump casing, reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.. Pumps are specially designed and manufactured to cater for a whole range of different applications.
