Explosion proof couplings

August 16, 2010 By Leslie Langnau Leave a Comment

Flexible couplings are a critical component for applications involving potentially explosive materials found in automotive paint and cleaning stations, chemical plants, and powder mixing areas.  A lack of radially flexible elements in shaft linkage can result in high radial loads on shaft bearings, eventually leading to heat generation and bearing failure, making flexible shaft couplings […]

Elastomer couplings with higher torque handling capacity

May 5, 2010 By Leslie Langnau Leave a Comment

The growing popularity of curved jaw (elastomer) style couplings for precision applications has driven the need for couplings that handle more than the traditional torque capacity of 2,150 Nm up to a maximum torque of 25,000 Nm. Available with split clamping collars or keyway and set screw connections, the three new body sizes allow for […]

6 ways to assess torque needs for safety couplings

April 8, 2010 By Leslie Langnau Leave a Comment

Safety couplings that operate on the ball detent principle primarily suit disengagement torque applications. But, with some modification, they can suit highly dynamic applications with resonant frequencies and torsional rigidity. Here is a brief examination of common equations used to calculate the following torques for safety coupling design in a drive system: disengagement torque, acceleration […]

Compact Precision Torque Limiters from R+W America

March 30, 2010 By Leslie Langnau Leave a Comment

Based on a compact and simple design, the ESL series torque limiters from R+W offer accurate performance at a reasonable cost. Unlike traditional ball-detent torque limiters, the ESL spring loads two series of ball bearings against one another to create a rolling effect at overload. The rolling effect reduces wear and at the same time […]

Six factors to remember about couplings in a motion system

March 25, 2010 By Leslie Langnau Leave a Comment

Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]

For safety, electronics may not be the best choice

March 18, 2010 By Leslie Langnau Leave a Comment

The trend of replacing mechanical systems with electrical systems continues. Even developers of hydraulic and pneumatic systems are following it. But, as is becoming evident through the latest unintended acceleration issues, electronic components can have a few drawbacks that should not be overlooked in a design. When in comes to designing a system for safety, […]

EZV Series Adjustable Line Shafts from R+W America

February 18, 2010 By CouplingTipsAdmin Leave a Comment

A convenient location for manual phase adjustment along a mechanical drive system is now available in the EZV series adjustable line shafts. Making use of a high strength intermediate collar between two telescoping sections of precision tubing, the EZV naturally places the location for phase adjustment in an easily accessible, open space. Due to the […]

High Torque Servo Couplings

July 6, 2009 By CouplingTipsAdmin Leave a Comment

Heavy duty torque ratings and high strength conical clamping hubs make BK3 couplings the choice for high torque servo gearboxes. Manufactured with a double-walled stainless steel bellows to absorb parallel, angular and axial shaft misalignment, the BK3 has an extremely high torsional stiffness to complement its relatively very low moment of inertia – allowing it […]
