Springs to design - Import export

SPIROL's Series 100 Key Fob Coiled Spring Pins were designed specifically to secure the key to the fob. The advantages of these high-performance automotive key fob security pins are as follows: Increased productivity, easy and trouble-free assembly, and simplified logistics.

DEWALT’s lead design engineer for drills was tasked with designing a high power right angle drill that is lightweight, compact, and portable. The goal with the design was to maximize performance while minimizing the size of the tool. The design would incorporate a mechanical clutch built to limit maximum torque output to 70 ft-lbs. Absent the clutch, with the huge gear reduction of 75:1, the drill would be capable of producing a lock rotor torque at the spindle of 175 ft-lbs, transmitted directly to the operator of the tool. It was determined early on that the clutching thrust required in the space available could only be achieved by a Disc Spring design. Compared to conventional coil springs, Disc Springs offer a higher load capacity in less space. Additionally, longevity and reliability is a high measure of quality for professional tools used on a daily basis. The life and performance warranty of the tool was reliant on the Disc Spring design.

SPIROL’s Dowel Bushings and Spring Dowels are designed to maintain alignment and are used to locate components with respect to each other. These roll-formed, hollow Alignment Dowels have lead-in chamfers that facilitate insertion into the holes of both mating components. The Dowel's flexibility enables absorption of wide hole tolerances and the staggered seam prevents interlocking. Dowel Bushings are designed with an inside diameter clearance that allows the passage of a bolt for fastening, thereby eliminating the need to drill an additional hole. They are also heat treated to isolate the bolt from shear loads.
