Springs and pressings


Torsion springs

Cut to the chase

The other day I read about a report from a school inspection in Canada a week ago. They were talking about safety in school and apparently old style paper cutters are a safety hazard since they don’t have safeguards on them. These safeguards available for paper cutters contain torsion springs on the blade arm. I didn’t know that. I guess I learned something new today :).

Think outside the box

Rubber, plastic or steel. It’s time to think outside the box when it comes to the most demanding, high-wear, abrasion and impact applications. Engineers are now working with cast polyurethanes. To make it work better, among many other things of course, the torsion spring is modified. Great job!

Beautiful power lines

My sweet torsion springs. So useful in many industries – one of the electrical power. How about this beautiful image of a bunch of power lines? And who said electrical power can’t be lovely…

Great machine park for efficient work

Let’s (torsion) spring into action and start the Easter holidays! Torsion springs are very commonly used since they are very flexible and with great machine parks the springs can even be made in only one machine. No extra handling needed. That’s what I call efficient.

Belt tracking

Conveyor belt mistracking causes great problems. Now the US is focusing on different belt training methods to help prevent these mistrackings. Here torsion springs are used in safety mechanisms for detecting both forward and reverse mistracking.

Fat Bike Ski

Forget about slalom skiing or snowboard, here’s something completely new to me – Fat Bike Ski. Between this fork mount and the ski is a dual pivot urethane torsion spring, which allows the ski to smoothly follow trail pitch without being too flimsy—think of it as an artificial ankle on a skier. Talk about great engineering!


Game changer used spring for pedals

Clipless padels came in the 1980’s and was a real game changer for the market. A torsion spring replaced the earlier used belt on toe-clip pedals, which made it a lot safer to ride since the pedal detach if the you fell down.

Tablet with hides torsion springs in the base

When the tablet Surface Studio was launched last year it had a screen that weight 13 pounds but feels weightless. Now that’s job well done. You can’t see it at the moment but there are torsion springs inside the bar that attaches the screen to its base horizontally.

Shed some light on spring torque force

New week! Let’s make it a good one and start by shedding some light on what makes torsion springs so great. In technical terms we’re talking about the torque performance, in this case . Torque is equal to force x leg length: M= F x A. Torsion springs have a linear spring characteristic, i.e. if a spring is turned 10° to provide torque of 1 Nmm, the same spring will provide a torque of 2 Nmm at 20° torsion. Interesting!
