• Sorting out shaft connections
  the coupling does not slip, torque transmitted through the shaft is: T = J/r. The polar moment of inertia is: J = r 4 /2. And , the yield stress for 35S20 steel, is 380 X 10 6 N/m 2 . For the example, J = 6 10 -9 m 4 and. This is the maximum torque that can be transmitted through the keyless shaft...
• Optical Shaft Encoders
  , modular, and kit. Standard encoders are those that have their own shaft and bearing assembly. The encoder shaft couples to the motor shaft with a belt, coupling, or gear train. Hollow shaft encoders are similar, but the motor shaft fits into the encoder shaft bore. Some manufacturers claim...

• Microfiber Ring Protects Bearings from Shaft Currents
  ones failed only five months later. Once again, that caused costly downtime and repair. In fact, a failed 1.5-MW generator can account for over $48,000 of lost revenue if down for a month, and repair costs can add up to as much as $50,000. Parasitic capacitive coupling between the rotor shaft...
• Application Note: Shaft Runout
  of shaft-to-shaft couplings or fixtures may occur. Misalignment, in turn, may subject the couplings, shafts, and bearings to excessive loads and premature wear. If a modular position encoder is mounted to a shaft with excessive runout, premature failure is likely. Runout tolerance is the total allowable...
• Rigid yet Flexible Coupling
  the steering shaft to the steering wheel and felt directly by the driver. Making the column assembly rigid and strong enough to prevent random vibration typically adds to the unit weight and cost. If the coupling assembly is loosely damped the effects are typically worse with random vibrations. Rigid yet...
• Precision coupling "shock proofs'' innovative packer
  material in an open-arm design helps transmit torque between shaft coupling hubs while damping shock and vibration. A servomotor powers pick-and-place motion in an innovative packing machine by means of a backlash-free coupling. The coupling damps out shock and vibration from the packing head's...
• Eliminating compliance in servosystems
  A traditional motor-mounting arrangement consists of a housed motor coupled to a lead or ball-screw shaft by a flexible coupling and a motor mount. A direct drive consists of a rotor assembly fabricated directly on the ball screw, eliminating duplicate motor parts, compliant couplings, and brackets...
• Taking torque around corners
  There are only a few coupling methods that work with high misalignment angles in rotating equipment. A spring retainer on the pins lets users quickly disassemble individual joints. A splined shaft lets two block-and-pin joints slip axially relative to one another. Perhaps a hundred different types...
• Getting the right angle
  , a hollow shaft, and integral stator coupling lead the pack in dynamic performance. They eliminate the need for a separate shaft coupling, which would increase the chance of introducing more error. The low-profile design also simplifies mounting. One such encoder uses the imaging scanning principle...
