Miki Pulley’s ALS couplings are general purpose power transmission couplings designed to transmit torque by connecting two shafts while damping system vibrations and accommodating misalignment. With a “Curved Jaw” design, ALS couplings feature a polyurethane elastomer element (called the spider) between two sintered aluminum hubs. The three-component assembly fits together with a jaw from each […]
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 […]
When should I use a zero-backlash jaw coupling?
Zero-Backlash jaw couplings are a good choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on proper coupling selection. The following is an excerpt from the jaw coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. “…We’ll go on to […]
Jaw couplings for precision conveyors
Ruland zero-backlash jaw couplings have a balanced design, accommodate all forms of misalignment and have high dampening capabilities, making them an ideal fit for precision conveyors with frequent starts and stops. These conveyor applications are often found on equipment used in semiconductor, solar, optical inspection, and medical automation. Jaw couplings offer system designers a wide […]
MJC-BL jaw-type, flexible coupling from NBK
The MJC-BL is a jaw type flexible coupling. A tight tit enables transmission with zero backlash at low torque. The easy fit allows users to assemble and partition the hub and sleeve smoothly. The coupling’s flexibility allows eccentricity, angular misalignment and twisting vibration to be accepted. It has electrical insulation and a resistance value: Not […]
How do you select the right coupling when electrical isolation is a priority?
By Joyce Laird, contributing editor Understanding design challenges Most of the couplings on the market today are either partially, or entirely, made of metal. Since metal is such a good electrical conductor it can be a challenge for the design engineer to find a suitable product to serve as a flexible coupling for transmitting torque […]
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. […]
Block shaft coupling advantages and disadvantages.
Advantages: Protects shaft-support bearings by exerting consistently low reactive forces, even under large misalignments Homokinetic transmission – driving and driven shafts rotate at exactly the same speed at all times Zero backlash and high torsional stiffness Electrical insulation Accommodates moderate radial misalignment in a short length Accommodates relatively large axial misalignment Easy installation in blind […]
Jaw In-Shear coupling
The Lovejoy Jaw In Shear (JIS) ring an insert allows any existing user of the standard Lovejoy Jaw design to upgrade to an in-shear design coupling. The JIS design allows for quicker element change-out for rapid intervention and production resumption. The JIS coupling uses the same simple maintenance procedure as the standard Lovejoy Jaw product, […]
The 4 best jaw couplings videos online
Good vibrations? Not really. When you need a coupling to handle impulse loads, misalignment, electrical isolation and more, jaw couplings are the most common choice. A staple in semiconductor, medical, solar and many other applications, jaw couplings are nearly everywhere. And so are the online videos featuring them. Here, we break down some of the […]
