JLB Racing Cheetah Differential Gearbox Stiffener

thingiverse

The differential gearbox housings of the JLB Racing Cheetah truggy are woefully inadequate when it comes to stiffness, resulting in a gear mesh that's severely off-kilter during heavy torque loads. This lack of sturdiness causes the sinter-pressed steel bevel gears to crack under the strain. To mitigate this issue, I propose treating the bevel gears with a thermal process that will render them less brittle. Simply place them in your oven for approximately 30 minutes at 250°C, and they should emerge with a blue surface finish. This treatment will impart a subtle softening effect on the gears, making them more resilient to heavy loads. However, to truly address the stiffness concerns of the gearbox housing, I recommend fabricating a stiffener using 3D printing technology. Utilize PLA filament with a sheet thickness of 0.3mm and an infill density of 100%. Once printed, secure the stiffener to the gearbox housing via screws and a two-component adhesive, ensuring a robust and durable bond that will withstand even the most demanding torque loads.
