The DIN 5462 standard is a foundational technical specification for . It is widely used in mechanical engineering to create secure, torque-transmitting connections between shafts and hubs.
). The standard defines three primary nominal dimensions that dictate the fit between the external spline (shaft) and internal spline (hub): Permanently fixed at 8. Minor Diameter (
pressure angle. Used for high-precision, high-rpm gearboxes. Manufacturing and Quality Control
Exact dimensions for the root fillets to prevent stress-crack initiation. din 5462 spline standard pdf exclusive
Power Take-Off units mounted on commercial truck transmissions (Allison, ZF, Eaton Fuller) transfer mechanical engine power to auxiliary equipment. DIN 5462 allows a hydraulic pump to slide directly onto the PTO shaft without intermediate couplings, reducing overhang mass and vibration. 2. Mobile Hydraulic Pumps
: These profiles typically utilize the inside diameter for alignment, though centering can vary based on manufacturing methods like hobbing.
Explicitly features a 4-spline design. It is highly specialized for mobile hydraulics and truck PTO systems. The DIN 5462 standard is a foundational technical
: Internal splines are primarily produced using push or pull broaching, or slotting machines for blind holes.
While the DIN 5462 standard covers a small range of sizes tailored to vehicle power transmission, the most ubiquitous profile found in industrial catalogs is the .
The specifies the parameters for straight-sided, internal and external splines with four splines in the series. It is a critical engineering benchmark primarily used for heavy-duty power transmission in automotive, hydraulic, and agricultural machinery. The standard defines three primary nominal dimensions that
The shaft and mating hub should share similar heat-treatment profiles (typically case-hardened to 58-62 HRC) to prevent one component from prematurely wearing out the other.
Detailed technical data sheets can often be found on manufacturer sites like If you are looking for tolerances for a specific fit or torque ratings
