Configuration and Features:

The spline is a kind of linear motion system. The torque is transferred when spline motions are made along the precision ground shaft by balls. The spline had a compact structure. It can transfer the overload and motive power. It has a longer lifetime.Currently, the factory manufactures two kinds of spline: convex and concave. Usually, the convex spline can take a more enormous radial load and torque than the concave spline.Linear motion rolling spline,(shown as Fig.1)has three rails sharing in excircle of spline shaft, balls are running in specific six loading paths formed by bulge outs of the three rails and the respective sections of spline nut.After the finished process, the radius of roller track slots is nearly the R-value of balls. When torsion force is pressed between the spline nut and the shaft, three torsion-oriented loading ball lines transform the force steadily and equally. When the orientation reverses, three other rows work. If a relative motion occurs between the shaft and the spline nut, balls will move back and forth between roller tracks and unload zone.The spline shaft is made of high-grade alloy steel quenching HRC 58, and the spline nut is made of high-grade alloy cementite steel quenching HRC 58, so long service life and hard intensity can be obtained.Clearance of rotating direction can be controlled to zero value or interfere state, high-speed motion, and spinning can be available; in addition, linear motion spline with compact structure is easy to assemble.

Code Rule and Connotation:

Accuracy Grade:

Spline series is divided into three accuracy grades,such as super as super-grade C,precision grade D and common grade E.Accuracy items see Fig.2.Allowable varaiation requirements of both axle necks of spline shaft are recommended for users.

Special Requirements For Shaft End

The fracture surface of the spline shaft is shown in Fig 10. When the axle neck of the spline needs some processing, make sure that:d<D(see tab.17;18;19)

Configuration and Mounting of Spline Nut

The correct mounting method is to keep the slot groove of the spline nut horizontal with mounting holes of the flange.Spline nut's slot grooves of GJZ, GJZA, and GJZG types, Shown as Fig.9(a), lie right two bearing ball lines.(a)GJZ, GJZA, GJZG type mounting section(b)GJF, GJFG type flange mounting section(c)GJZD mounting sectionMounting of Spline NutWhen fitting the spline nut to the mounting base, please push it in with proper tooling. Do not touch the side plate and sealing gasket—tool di front end faceoff angle 2*30°. 

Size of Proper Tooling:

Assemble the axle with a spline nutWhen fit spline shaft with spline nut, pay attention to watch that matchmarks to avoid mistake.No permission fitting with reckless force. Lubrication oil is recommended for external diameter of main axle. Shown in Fig.13.
