What is the difference between steady state and max torque
Bobby Watkins for Ruland Manufacturing on steady state and max torque: The difference between steady state and max torque. In many applications, there is a motor, which has a maximum torque rating, but it’s never used. Some people like to size their coupling based on max torque, and the coupling still may be able to handle it, […]
What are some different styles of disc couplings?
Disc 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 disc coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Specifically, Watkins covers different styles of […]
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 […]
Do bellows couplings require precision alignment?
Bellows couplings are an excellent 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 bellows coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Bellows couplings are for precise […]
What are couplings for power-transmission drive shafts?
Updated May 2019 || 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 […]
Zero-backlash jaw couplings: Drawbacks and benefits
Updated October 2019 by Lisa Eitel || Zero-backlash jaw couplings are suitable for an array of applications. Here, Bobby Watkins of Ruland Manufacturing sheds some insight on their benefits and drawbacks. Zero backlash jaw couplings are our fastest growing product over the last 10 years. They’ve got some great characteristics under the right circumstances. There […]
What are the pros and cons of beam couplings?
Beam couplings are an excellent 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 beam coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. “We’re going to start off […]
Machines use Zero-Max CD couplings for component balancing
Now some balancing machines incorporate pre-balanced CD Couplings from Zero-Max to get reliable system performance. Prebalancing aids on-machine trim balancing during assembly into the balance machine. CD Couplings have a combination of operating characteristics that support reliable automotive-component balancing. Making this possible is the coupling’s proprietary Composite Disc pack which in this application is designed […]
Regal Beloit coupling maintenance for critical equipment- Pt. 1
Regal Beloit Corporation, is a manufacturer of electric motors, electrical motion controls, power generation and power transmission components. Unplanned outages due to mechanical failures can cost millions of dollars of lost production time to Oil and Gas companies. While it’s difficult to quantify the cost of unplanned downtime, an outage of a single day may […]
