Ball Spline

Model: SLT/SLF

Category:

Exhibitor: PRECISION MOTION INDUSTRIES, INC.

Booth No: K116

Characteristic

Design Principle︰The ball spline has load groove of three row on the outside diameter of shaft. Due to the gothic arch groove design, it could be make sure three grooves withstand clockwise or counterclockwise of torque at the same time, and then increase the service life and rigidity. The balls re circulation in ball holder, prevent balls falling from the spline nut while assembling.
Features
1.Large Load Capacity︰Every groove of the shaft is precision ground to form a 30° angular contact points. Thus, this model has large load capacities in the radial and torque directions
2.No Angular Backlash︰At a contact angle of 30° to provide a preload in an angular-contact structure. This eliminates an
angular backlash in the rotational direction and increases the rigidity.
3.High Rigidity︰Due to large contact angle, it can give proper preload subject to availability. Thus, it can get high rigidity and large moment.
4.Ball Retaining Type︰With ball holder, prevent balls falling from the spline nut while assembling.
5.Application︰Robots, Transporting equipment, Wire winder, ACT (auto tools change)…etc.
Types of Spline Nuts
1.Cylindrical Type Ball Spline Model SLT︰The most compact type with a straight cylindrical spline nut. When transmitting a torque, a key is driven into the body.
2.Flange Type Ball Spline Model SLF︰The spline nut can be assembly to the housing via the flange, making assembly simple. Due to keyway is machined, thus it may be deformed, and where the housing width is small. It is most suitable for model SLF.
