PARALLEL SPLINE HOBS

Parallel Spline Hobs are specialized cutting tools engineered to produce straight-sided, parallel-key splines on shafts and in bores. Unlike involute splines, which feature a curved tooth profile, parallel splines are characterized by teeth with flat, parallel flanks that mate with corresponding grooves. This design, often specified by standards such as ANSI B92.1, provides robust torque transmission capabilities, particularly in applications where the components are subjected to significant radial loads. Parallel spline hobs are meticulously designed to ensure precise tooth spacing and accurate control over the spline’s major and minor diameters, ensuring a secure fit between mating parts. They are commonly employed in heavy machinery, agricultural equipment, and other industrial applications where a strong, non-sliding connection is required.
