conical spring

If made with constant pitch (wire thickness), conical springs will have a variable rate.

However, a conical spring can be made to have a constant rate by creating the spring with a variable pitch.

In 1848 Brown developed and patented the conical spring buffer for railway carriages, which was very successful.

A conical spring system was proposed to replace the complex and costly dual torsion bar system.

A conical spring may be used to guard drill bits, or some protection may be provided by a proper arrangement of drill bit length.

Coil spring or helical spring - a spring (made by winding a wire around a cylinder) and the conical spring.

These used oiled leather friction surfaces between bronze disks compressed by adjustable conical springs, with the disk pack floating between arms to both chassis and axle, in the distinctive style.

If a short grip length can not be avoided, the use of conical spring washers (Belleville washers or disc springs) can also reduce the loss of bolt pre-load due to embedment.

The club armchair first appeared at the start of the 20th century, with the application of a new padding technique, using double conical springs not only in the seat cushion but also in the backrest and armrests.

A Belleville washer, also known as a coned-disc spring, conical spring washer, disc spring, Belleville spring or cupped spring washer, is a type of spring shaped like a washer.

Compared to these earlier designs however, the amount of drilling and machining involved in producing these Standardpanzer was reduced drastically, which would have made them quicker, easier and cheaper to produce, as would the proposed conical spring system, replacing their predecessors' torsion bar system which required a special steel alloy.
