Bevel Gear Assembly Diagram - Mechanical Engineering Reference #113517 (License: Personal Use)

This black-and-white engineering diagram depicts a bevel gear assembly, likely part of a vehicle differential or industrial gearbox, with interlocking conical gears and a manual adjustment lever (c). Labels 'a' and 'b' indicate structural sections-possibly the pinion housing and carrier casing-while dashed lines suggest internal clearances or mating surfaces. The precise linework reflects early 20th-century mechanical drafting standards.

Used in technical manuals, engineering textbooks, or automotive repair guides to explain gear train geometry, torque transfer, and differential operation; targets students, technicians, and mechanical designers seeking functional understanding.
