Volute Springs

Volute springs, also called vertical volute springs or pagoda springs, are springs shaped like bamboo shoots that have a rectangular cross-section wound in a conical shape. Volute springs can produce a large load and absorbenergy relative to the space and volume where volute spring occupies, making them a suitable spring for shock absorbers. The thickness of volute springs varies from 1 mm or less up to about 32 mm. Large volute springs can support loads up to 500 kN.


We also provide custom volute springs. Welcome to contact us to get detailed information of volute spring. 

Description

Volute Springs are used as compression springs and made from flat material coiled to a volute. The coils of the material overlap each other and are guided radially by each other during compression, thus giving volute spring a stability against buckling that cannot be achieved with conventional compression springs. By using volute springs, it's possible to achieve shorter installation lengths than for compression springs. It all depends on forces and dimensions.


HEGONG is an expert of volute springs manufacturer and supplier according to JB/T11698-2013 standard, whcih HEGONG participated in drafting. Its main features are small size and large load. It is widely used in small spaces and large loads for vibration reduction. For example, volute springs are popularly applied in secateurs for gardening and railway buffers. It has three structures as Equal helix angle, Equal pitch, and Equal stress.


Production Process of Volute Springs 

● Preparations for materials
The materials of the volute springs are really long and thin boards.We coil this around a coiling arbor to make form.

 Coiling

We heat the materials at a high temperature after we coil it up in a spiral. At this time, it is “a gap” to be important.

 After coiling

This gap will be a big influence on shape, dimensions and load properties. It is the time when experience and the skill of craftsmen stand out. And this is a volute spring after coiling.
