Spline Shaft

Splines are parts that transmit power through the movement of interlocking grooved rotary shafts. Since splines transmit power by meshing together many tooth surfaces, they have superior load transmission ability and alignment relative to fasteners such as screws, pins, keys or mechanical locks. The main types of splines are square splines (with linear and parallel groove side surfaces), involute splines (with zig-zag tooth shapes in circular arrangements) and ball splines (that generate linear motion from rolling steel balls placed in the grooves). Splines that can transmit large torques are used in a variety of mechanisms such as automotive and high-speed rolling stock transmissions, propeller shafts, transportation equipment and machine tools. There are a wide range of applications, so an extensive lineup of product types and shapes are available.

Spline Nut

THK

The nut and shaft are sold separately. Use together with THK nuts and shafts (DPM, DP, SS). The shaft is cut with no surface treatment.

[Features]
· The spline nut DPM type / DP type is a low-priced bearing where a special alloy has been die cut with a high precision splint shaft as the core.
· Differs from conventional machine processed units, and has excellent abrasion resistance due to there still being the same chill layers that were formed on the sliding surface during the casting process.
· The spline shaft used in combination with this can be roll-pressed to machine harden the surface, and provide the surface with a mirror surface finish, to achieve smooth sliding.
· The spline cog has a special design with a large contact area and has concentricity that can automatically determine core when torque is incurred, so the torque...
