The Nitriding Spur Gear with Internal Spline is a precision-engineered mechanical component that integrates internal spur gear teeth and internal spline features within a single cylindrical structure. This advanced design enables efficient torque transmission while accommodating axial movement in compact industrial systems.

The outer section features spur teeth machined on the inner surface of a cylindrical ring. These parallel-axis teeth employ standard involute geometry for smooth meshing and optimal power transmission efficiency.

The inner section contains evenly spaced parallel ridges along the circumference, engaging with mating external splines to transfer torque while permitting axial movement and alignment adjustments.

Both gear and spline features share the same central axis, with the spline positioned radially inward of the gear teeth. The component thickness is engineered to maintain structural integrity under heavy operational loads.

• Dual Torque Transmission: Internal spur gear meshes with external pinion while internal spline connects to shaft or hub
• Space Optimization: Eliminates need for separate assemblies, reducing axial length and weight
• Axial Compatibility: Accommodates thermal expansion, misalignment, and axial adjustments
• High Load Capacity: Designed to withstand heavy radial, axial, and torsional loads

• Automotive transmissions for planetary gear sets and shaft connections
• Robotics joint actuators with space constraints
• Aerospace systems requiring lightweight, high-reliability power transmission
• Heavy machinery gearboxes for construction and mining equipment
