The LEGO® Technic 24-tooth crown gear is the specialized part engineered for that exact purpose. It allows you to transfer rotational power 90 degrees, making it an essential component for any build requiring a **Technic right-angle gearbox**. This gear is fundamental for creating realistic vehicle drivetrains, a responsive **custom LEGO steering system**, and other intricate industrial machinery where a direct line of power isn't possible.\u003c\/p\u003e\n\u003ch3\u003eApplications and Creative Uses\u003c\/h3\u003e\n\u003cp\u003eThis gear is the perfect solution whenever your mechanism needs to make a right-angle turn without losing power or precision, enabling sophisticated **90-degree power transfer**.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Drivetrains:\u003c\/strong\u003e Use it to connect the main driveshaft to the axle, forming the core of a **LEGO vehicle differential** for cars, trucks, and all-terrain vehicles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteering Systems:\u003c\/strong\u003e Create responsive and realistic steering by using a crown gear to translate rotation from the steering column to the wheel axle assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Machinery:\u003c\/strong\u003e Build custom gearboxes, conveyor belts, or any mechanism where power needs to be routed around corners efficiently and reliably.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTo create your next advanced mechanism, pair this crown gear with other parts from our extensive \u003ca href=\"\/en-global\/collections\/collections-lego-technic-gears\"\u003eTechnic gears collection\u003c\/a\u003e, along with structural parts like \u003ca href=\"\/en-global\/collections\/lego-technic-axles-wheel-holders\"\u003eaxles\u003c\/a\u003e and \u003ca href=\"\/en-global\/collections\/lego-technic-beams\"\u003ebeams\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart ID:\u003c\/strong\u003e 3650b\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Count:\u003c\/strong\u003e 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Crown Gear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Transfers motion at a 90-degree angle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Meshes with standard spur gears like the 8-tooth (Part 6589) and 24-tooth (Part 3648).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eA Little Piece of Trivia\u003c\/h4\u003e\n\u003cp\u003eThis reinforced version (3650b) is an evolution of an earlier design. The original 24-tooth crown gear (3650a) was introduced in the late 1970s, but its design was a compromise, as it also had to function as a regular spur gear. This \"new style\" version, introduced in the early 1980s, features reinforcements that provide greater strength and durability, making it far more reliable for high-torque applications and a mainstay in Technic sets for decades.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDon't let a simple corner stop your complex creation.
