All couplings transmit torque and angular velocity. Flexible variations compensate for misalignment. Many of the latter even address vibration and improve system dynamics. Design considerations include machine or installation construction and backlash, torsional stiffness, damping, inertia, torque ratings, maximum rpm, size, misalignments, ease of installation, robustness, and cost. For power transmission (as in motors for […]
Spindle safety system
Despite current CNC machine tool crash protection strategies which include both proactive avoidance through CAD/CAM programming and reactive damage reduction methods that include electronic sensors and mechanical overload clutches, machine tool crashes are still commonplace. In these machine tool crashes, tool collisions with high feed rates cause high forces on motor spindles. Depending on the […]
Sectional rail couplings from GAM
Coupling technology designed for sectional gripper-rail attachment in transfer systems used in press automation. Featuring a patented force amplification system, the clamping design assures a high stiffness and high precision connection. The lightweight, compact high-durability couplings can be adapted easily to every current gripper-rail profile. Not only can the sectional rail couplings be installed by […]
The year in couplings 2016: GAM
For this multi-part series, Coupling Tips.com reached out to several coupling industry professionals to get their take on the year in couplings. Here, GAM Technical Marketing Manager, Mike Parzych looks back on 2016 and gives a few predictions for the new year. Coupling Tips: What do you think was the biggest event in the industry […]
GAM expands U.S. manufacturing
GAM Enterprises, a U.S. owned and operated company announces the expansion of their U.S. manufacturing operations and introduces a 1-week quick delivery program for gearboxes and couplings. With a goal aimed to improve delivery and overall customer satisfaction, GAM established full U.S. manufacturing at its headquarters in Mount Prospect, Illinois. GAM transformed operationally from light […]
GAM hosts new manufacturing event
GAM hosted an Open House event to showcase recent manufacturing expansion and new service programs at its Mount Prospect, IL headquarters. A number of dignitaries attended the Open House including U.S. Congressman Bob Dold, Mt. Prospect Mayor Arlene Juracek, Mark Dietzen of Senator Mark Kirk’s office, District representative Victoria Williams, along with members of the […]
Bellows Coupling: Understanding and Applications
What is a bellows coupling? According to Mike Parzych, Product Marketing Manager for GAM, a bellows coupling is basically a type of coupling design which consists of a thin walled, flexible corrugation (bellows) that is connected between two clamping hubs. “These types of couplings are traditionally used for servo motion control applications that have high […]
What is a conical clamping hub?
By Joyce Laird, contributing editor Understanding the application to create a perfect match is always the first step in any process. Understanding the parts that go into that application are the key to that perfect match. So, first it is important to understand what a conical clamping hub is. A conical clamping hub is a […]
What are some types of coupling shaft connections?
By Joyce Laird, contributing editor All couplings relate to the connection method between the coupling hub and mating shaft. Mike Parzych, Product Marketing Manager for GAM explains that within this area, there are many things to consider when selecting the proper mating connections. “Keyed couplings have a key slot machined into the hub that accepts […]
Safety coupling basics: What does a ball-detent do?
Couplings are common motion system components used primarily to transmit torque and compensate for misalignment between two shafts. Safety couplings, or overload couplings, are specially designed couplings that slip or disengage in the event that a pre-determined torque limit is reached. The most common type of safety coupling is a low or backlash free spring-tensioned […]
