The POLY shaft coupling is a torsionally flexible shaft coupling (safety coupling) for general engineering. CoryPad is actually correct, although 0.577 rather than 0.6 is better recorded in the various engineering literatures under "Maximum Distortion Energy Theory". Flexible couplings are used to connect two shafts having lateral or angular misalignment. Figure 16.2 shows Clamp Coupling assembly. Motor starts on NO load thus reducing initial increase in current and power consumption. Shafts are designed on the basis of torsional shear stress induced because of the torque to be transmitted. Jaw In-Shear 6 Pin Coupling Unique 6 pin locking system Utilizes the standard Lovejoy L and C Type hub design Non-fail safe (torque will not be transmitted if elastomer fails) Radially removable spider allows easy maintenance No metal to metal contact Resources Simple and virtually indestructible, the pin and bush design is ideal for applications that involve safety, such as elevator drives or fire pumps.

When a certain torque is reached the pin should rupture and no torque transmitted. Finally, despite all of our efforts to avoid coupling failure, our installations and our personnel need be able to adequately respond to failure modes which experience shows are credible. Another variant of the chain coupling uses silent chain in place of roller chain. The shear pins I have used in the past do not have sharp notches, but rather a radiused groove to ensure failure at the correct point, so as not to bugger up the entire coupling and shaft arrangement. If T is the torque to be transmitted, tangential force, 16.5.2.5 Design of Bolts. Following standard proportions are used in the design of flange coupling: Outer diameter of hub, D = 2 d, Pitch circle diameter of bolts, D1 = 3 d, Outer diameter of flange, D2 = 4 d, Length of the hub, L = 1.5 d, Thickness of flange, tf = 0.5 d, Thickness of protective circumferential flange, tp = 0.25 d. where d is the diameter of shafts to be coupled.

These two halves are clamped together with the help of bolts, which are placed in recesses made in the sleeve halves. A correctly installed and dimensioned discpack coupling lifetime is at least as long as that of the connected machines, and it requires no maintenance apart from visual inspection. 2. For example, after a disc pack diaphragm fracor s or tureafter shear pin coupling. . The coupling is threadably connected to the sucker rod and the pump during normal operations, but can relatively easily be parted, if the pump becomes stuck, by pulling up on the still free sucker rod string. Failure shear pin. Where T = Twisting moment (or torque) to be transmitted, J = Polar moment of inertia about the axis of rotation, r = Distance from neutral axis to the outer most fibre = D/2, 16.5.2.3 Design of Key, In this case two separate keys are used for the two shafts. 16.3.2 Design. A single piece elastomer (Spider type, Snap-wrap type coupling) is used for low to medium power applications, while individual elastomeric elements are used for high power application (T cushion type coupling). In their most basic form, they incorporate a pin (or, for very high torque ratings, multiple pins) inserted between two rotating elements, such as discs or flanges. Figure 16.2 Clamp Coupling. Vertical drives can be equipped with the KKT3, which is fitted with a limiter plate inside the coupling. I am trying to design a shear pin that will connect two drive shafts.
