  • Proper Shaft Fits for Precision Coupling Devices
    When sizing high performance drive components, proper shaft fit is an important consideration in helping to maintain concentricity and balance in the rotating equipment. In v-belt drives, chain drives and other low-cost / low-speed systems, designers often give little thought to shaft fit. Many
  • Sorting out shaft connections
    of 35S20 steel, with key and keyway dimensions sized according to DIN Standard 6885. The following calculations determine the maximum torque that can be transmitted through both keyed and keyless shafts, as well as the maximum transmissible torque for the key. Assuming the coupling does not slip
  • 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
  • Dimensions & Tolerances for Flat Keys & Keyways per JIS B 1301:1996
    When designing a drive system, the use of keys and keyways to transmit torque from the drive shaft to the gear/pulley/sprocket/coupling is common. Enclosed is a table detailing the standard metric keys and keyway sizes and their corresponding tolerances.
  • 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
  • MTBF APPROACHING INFINITE
    The concept of fatigue resistance in flexible shaft coupling design has been highly valued by R+W since its inception in 1990. For much of its first two decades in business the company focus was almost exclusively on couplings for high performance servo drive technology. When it comes to machinery
  • What to look for in a servocoupling
    Torque, shaft misalignment, stiffness, rpm, and space requirements are some of the factors to consider when selecting a coupling for servo applications. Servocouplings come in a variety of designs but all have zero backlash. Servocouplings are typified by their ability to transmit torque with zero
  • Taking torque around corners
    of couplings can join rotating drives when there is just a small misalignment between shafts ( <3°). But designs with misalignments approaching 10° or more leave just three choices: Cardan-type universal joints (automotive-style needle bearing and block-and-pin), and flexible shafts. joints, also
  • May the force loop be with you
    High-thrust linear motors make it possible to use force servoloops to suppress stiction. Tubular linear motors from California Linear Devices are three-phase, direct-drive, brushless dc motors with NdFeB permanent magnets that can hit positioning resolutions down to 1 micron. Standard stroke
