Metal shaft LBG series

driveball splinetransmission

With the rotary ball spline, the spline shaft has three crests, and along both sides of each crest, two rows of balls (six rows in total) are arranged to hold the crest so that a reasonable preload is applied. These models are unit types based on the Model LBR, but have gear teeth on the flange circumference and radial and thrust bearings on the spline nut, all compactly integrated. The rows of balls are held in a special resin cage so that they stay aligned and recirculate. With this design, balls will not fall even if the spline shaft is removed. With the Rotary Ball Spline, the spline shaft has three crests, and along both sides of each crest, two rows of balls (six rows in total) are arranged to hold the crest so that a reasonable preload is applied. These models are unit types based on model LBR, but have gear teeth on the flange circumference and radial and thrust bearings on the spline nut, all compactly integrated. The rows of balls are held in a special resin retainer so that they smoothly roll and circulate. With this design, balls will not fall even if the spline shaft is removed. No Angular Backlash The spline shaft has three crests positioned equidistantly at 120° and along both sides of each crest, two rows of balls (six rows in total) are arranged so as to hold the crest at a contact angle of 45° and provide a preload. As a result, backlash in the rotational direction is eliminated and the rigidity is increased. Compact Design The spline nut is compactly integrated with radial and thrust bearings, allowing compact design to be achieved.
