Davall Gears Ltd

Davall Gears Overview

Davall Gears Ltd specialises in the design and manufacture of gearboxes and gearing systems. Our products are used right across the aerospace, defence, medical, industrial and automotive sectors, for both development and production purposes. Our accreditations include:

• BS EN ISO9001:2000
• AS9100: Rev. C
• NADCAP

These ensure our products meet the quality standards demanded by industry. 

Using a series of state-of-the-art CNC machine tools, EDM equipment, profile grinders, worm thread grinders and gear cutting machines, we’re able to deliver a complete range precision engineered components and assemblies. 

Davall Spiradrive

Spiradrive® is the name given to our spiroid gearing products, which consist of a gear and pinion that give a much greater torque capacity for a given package space than other, competing right-angled/offset gear systems. Higher torque is achieved by having a large contact ratio (i.e, number of teeth sharing the torque loading). Spiradrive® systems also give exceptionally low, and in fact virtually zero gearbox backlash (subject to manufacturing and build processes). To find out more, head over to our website or get in touch with a Davall expert on 01707 28 31 00.

Design & Engineering

Drawing upon a wealth of industry experience, our design and development team are able to offer both clean sheet solutions and complete gearset or transmission re-engineering services to meet new application/performance targets. 

Whatever your design requirements, we’ll deliver a practical, cost-effective solution. The service includes design, analysis, prototyping and product testing, all of which are carried out within a single site facility. Once all tests have been completed and the final product approved, we can then begin the manufacturing process. 

If you need a new gear component developing or an existing one re-engineering, speak to the team at Davall on 01707 28 31 00.
