Many environmental considerations affect coupling selection. There is moisture, chemicals, and vacuum, to name a few. The different types of motion-controlled couplings have a different capability in handling different environmental considerations. You want to know moisture level, any chemical presence or if you’re dealing with a vacuum and you don’t want any outgassing, that’s an important […]
What do I need to know before selecting an Oldham coupling?
Oldham couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the Oldham coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Zero backlash Oldham couplings are […]
What are couplings for power-transmission drive shafts?
As outlined in our coverage of couplings for motion control — here at this couplingtips.com article — couplings connect rotating shafts powered by a drive of some type — often an electric motor. All couplings serve to transmit drive torque and angular velocity. But applications for motion control (such as axes to position loads) usually […]
Environmental considerations for coupling selection: fast facts
It takes more than just specifying size, speed rating, and torque range to assess the right coupling for an application. One of the most important factors is a coupling’s operating environment. The conditions a coupling will face can have a drastic impact on efficiency and service life. To learn more about a few environmental consideration […]
Tips for understanding torque with bellows and Oldham couplings
It’s important to note the difference between steady state and max torque based on motion type or when using a bellows vs. a disc coupling. It’s also important to understand how couplings are rated. Jaw couplings have a peak torque, for example, and rigid couplings have a superior torque capability but do not allow for […]
Oldham couplings for actuator driven systems
Ruland Manufacturing Co., Inc. presents Oldham couplings for actuator driven systems. The Oldham couplings are zero-backlash, have a balanced design, and high parallel misalignment capabilities, making them an ideal fit for screw driven actuator applications. The three-piece design allows designers to easily couple an actuator and motor that have keyed or keyless shafts with inch […]
Misumi Oldham couplings
Couplings are machine components designed to connect two separate rotating bodies and transmit a torque between them. They allow various misalignments (Lateral/Angular/Axial) of the rotating bodies to be absorbed, and alleviate installation and adjustment work loads. Furthermore, they protect expensive inter-connected machine components from sudden and unexpected excess loads by breaking and disconnecting. Oldham couplings, […]
NBK’s MJ jaw couplings for power-transmission designs
NBK’s MJ jaw couplings are suitable for power-transmission designs. They can transmit high torque and address reasonable levels of misalignment. They also impart vibration absorption … … just a few reasons why jaw types are widely used in PT applications. If an application needs the coupling to address more misalignment, NBK offers MOR Oldham-type couplings. […]
The 5 best Oldham couplings videos on the web
Oldham couplings are considered a workhorse in light load, servo applications. With their electrical isolation potential, zero backlash and misalignment capabilities (okay, maybe not angular), Oldham couplings are a familiar face in motion control applications and general industrial equipment. In this list, we take a look at some of the best Oldham coupling videos on the […]
