pre-winding power springs

­Pre-Winding Power Springs

Power Springs are used to create a compact power source in applications that require counterbalancing, sometimes through a cable/cord retraction mechanism. The small size and rotational output of Power Springs make them fantastic options for manufacturers and engineers. Vulcan’s Conpower Springs are pre-stressed, producing a flatter torque profile than conventional Power Springs. When a project …

Shelf Management: Keeping it Organized with Pullboxes

Recently I went to a “large” retailer to find a few items on my list.  When I was at the checkout counter I witnessed a mild disagreement about a price.  The register rang up one amount, and the shopper thought the price was a much lesser amount.  Of course, a supervisor was called into action …

Design and Function of a Twin Spring or Motor Brush Spring

One of the most unique spring designs produced by Vulcan is called a twin spring.  Its name is derived from the characteristic of having two springs formed from the same strip of stainless steel material.  These custom springs are intended to work together, in unison, doubling the force of a single spring.  Twin springs are …

Constant Force Springs Explained

What differentiates the constant force spring from the conventional extension and compression (round wire) spring? Hooke’s Law states that the extension of a spring is directly proportional to the load applied to it. Therefore, the further an extension spring is extended, the greater the force.

Creating More Force with a Constant Force Spring

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 much smaller spring design may …

Power Spring Design Requirements & Calculations

What Are Power Springs? 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 the case where it’s retained. What Are Pre-Stressed Power Springs? Pre-stressed power springs (Conpower®) undergo additional processing to yield a slightly flatter torque …

FIRST Robotics Competition Uses Vulcan Springs

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 Spring 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 thrive in the STEM areas …
