With more models, sizes, and ratios, DieQua's Tandler spiral bevel gearboxes offer precision, performance and durability far above standard products. They're ideal for applications requiring high-speed, precise motion control, high torque, or heavy shocks. Several configurations, options, and customized solutions provide unmatched design versatility.
This paper presents a joint project conducted by Ashwoods Electric Motors and Oerlikon Fairfield that uses planetary drives with an integrated electric motor. Current solutions used in production of off-highway vehicles rely upon large, heavy and inefficient brushed DC or induction motors, coupled to a planetary gearbox. This presents a number of challenges to the vehicle designers such as: limited vehicle range, limited space around the motor/drivetrain, and motor durability.
The proposed integrated system utilizes an Oerlikon Fairfield Torque Hub, widely used in off-highway vehicles, and the
Ashwoods first-to-market, interior permanent magnet motor. How these products are integrated, i.e. incorporating a brake solution, represents a market-changing product. Using interior permanent magnet (IPM) technology in the motor design means the motor can be up to 70% lighter, 70% smaller and 20% more efficient than traditional motors used in off-highway
traction applications.
Worm gear drives, consisting of two parts: a steel worm gear and a bronze worm wheel are used in commercial and industrial applications where fast braking or stopping is required, space is limited, and noise is a concern. For precision gears, custom gearboxes and power transmission components go to SDP/SI.
