Industrial/Commercial

  • Industrial/Commercial

    Opposed to Aerospace Gears and components in which flight safety and quality is more in focus than component cost, Davall are able to manufacture precision gears for low to medium volume commercial products where cost and quality are absolutely critical. Often designs are developed to provide parts of the Geartrain in injection moulded plastics which can provide appropriate performance of a much cheaper to produce part. The sample part shown is in an industrial door opener product in which a strong metal "hub and disc" has been moulded into a bevel gear to combine strength and rigidity and hub drive torque capacity, without the cost of a full metal part.

    Davall can produce tooling and supply in production of most types of gears in lower cost materials.


  • High Performance Spinning Fishing Reel

    Sector: Commercial

    Background/Requirement:

    • Premium application product High standards for Subjective "feel" of smoothness.

    Davall Scope/Key Challenges:

    • Exceedingly compact Gearset Lowest numerical Spiradrive® ratio achieved in a production application (5.6:1) High accuracy gear profile and surface finish at low cost Subjective rating targets very high for a "premium product".

    Results:

    • Gearset in production supply at very high quality levels for a most critical "subjective feel" gearset.

  • High Power Hydraulic Systems Power Take Off Unit

    Sector:  Commercial

    Background/Requirement:

    • High performance racing Yacht.
    • Requirement to drive a high power Hydraulic Pump driven from the propulsion Diesel Engine.
    • Dynamic engagement under load and speed.
    Davall Scope/Key Challenges:
    • Compact space between Engine and propulsion gearbox
    • Requirement to achieve reduction ratio in min package and weight
    • Dynamic engagement at load and speed
     Results:
    • Concept design signed off by the customer achieving package requirements
    • Single system prototype unit designed and supplied
    • Built onto Engine and Gearbox on same day as unit delivered
    • Client very pleased with speed and quality of project  

  • High volume Industrial Door Opener Geartrain

    Sector: Commercial

    Background/Requirement:

    • High volume geartrain for an industrial door opener
    • High cycle reliability
    • Low cost intermediate gear wheel developed as a "Moulded" Spiradrive wheel linked to a hardened steel pinion
    • Moulded gear developed around a steel hub for rigidity and support of the moulded gear teeth

    Davall Scope/Key Challenges:

    • Design gearset and advise on load and safety factors
    • Complete "electrodes" to manufacture injection moulding
    • Complete tooling design and manufacture for moulded gear
    • Complete manufacture of prototype and test samples

    Results:

    • Gearset completing prototype development phase
    • Initial production order in progress
