It’s time for FIRST robotics to kick off and, as of Tuesday, the robots are finished and waiting for the first competition of 2012. Vulcan has sponsored Team 1218 of FIRST Robotics for the last few years. We see this as a great way to help schools train kids to … Continue reading
Telford, PA., USA – Vulcan Spring and Manufacturing Co., a leading designer and manufacturer of flat steel springs and related assemblies for diverse global markets, announces the launch of their new full-featured re-designed web site at www.vulcanspring.com. The new site offers simpler navigation, more content including videos and multimedia, the … Continue reading
Vulcan Spring’s products are primarily manufactured from AISI Type 301 Stainless Steel. The resistance of this steel to general atmospheric corrosion is very good. However, they may be adversely affected when exposed to certain chemicals or environments, which may induce hydrogen embrittlement, stress corrosion cracking and corrosion fatigue. While we … Continue reading
When considering a spring design it can sometimes be important to discuss the edge condition of the steel. There is a vast amount of technical information concerning the edges of slit strip, but in this blog we will only discuss the basic characteristics and some of the benefits of each … Continue reading
Our last blog discussed the two main types of Constant Force Spring; linear force and torque. As you can see by the following graph, Vulcan is able to change the force of the spring over the travel length to match customer requirements. These springs are referred to as Gradient Positive … Continue reading
What differentiates the Constant Force Spring from conventional extension and compression (round wire) springs? As shown by the graph below, Constant Force Springs are not bound by Hooke’s Law and provide a constant force over the length of travel. Hooke’s Law basically states that the extension of a spring is … Continue reading
A frequently asked question concerns the life cycle rating of a Variable Force “V” Spring. In this blog we will focus on this discussion and how the life cycles are analyzed. Let’s first give a brief description of what a variable force spring is and what it looks like. A … Continue reading
A common practice for mounting Constant Force Springs is to utilize two or more springs to gain more force in a small space. This might be required if the diameter or width of a single spring exceeds the allotted space but there is room to add multiple smaller springs. A … Continue reading
One of the most common questions about Constant Force Springs concerns the mounting of the spring on a spool. For starters, the spring doesn’t have to be mounted on a spool; it can be placed in a cavity or on an undersized bushing or pin. There are differences in the … Continue reading
Power Springs are formed by winding strip material on an arbor and into a case or retaining ring. Power springs store and release torque through a central arbor or through the case that it is retained in. Pre-stressed power springs (Conpower®) undergoe additional processing to yield a slightly flatter torque … Continue reading
