Lbr Ball Spline/Linear Motion Spline/Linear Ball Spline for Robot

  • Model NO.: LBR15/20/25/30/40/50/60/70/85/100
  • Specification: N/A
  • HS Code: 8483401000
  • Trademark: N/A
  • Origin: Cn
Quantity:
The Ball Spline is a rolling guide spline bearing. It is an innovative product with a ball rolling on a groove connected to the shaft, realizing allowable loads greater than with linear bushing and enabling torque transmission while making linear movements.
 
High torque type- LBS/LBST/LBF/LBR/LBH
This Ball Spline has no angular backlash to increase the rigidity by providing a preload with one spline nut since the spline shaft has 3 crests equidistantly arranged at 120 degrees on the circumference, each held by 2 rows (6 rows in total) of balls under a load .
Application:
Column and arm of industrial robot
Automatic loader
Transfer machine
Automatic conveyance system
Tire molding machine
Spindle of spot-welding machine
Guide shaft of high-speed automatic coating machine
Riveting machine
Wire winder
Work head of electric discharge machine
Spindle drive shaft of grinding machine
Speed gears
Precision indexing machine

How to select a ball spline?
1. Setting conditions
Stroke length, velocity, magnitude of the applied load, mounting space, operating frequency, required service life, dimension(No. of spline nuts, span), installation direction, environment, accuracy.
2. Selecting a type
High torque type-LBS/LBST/LBF/LBR/LBH
Medium torque type-LT/LF/LT-X
Rotary type-LBG/LBGT/LTR/LTR-A
3. Studying the spline shaft strength
Estimating the spline shaft diameter/length, permissible load on the spling shaft, displacement of the spline shaft(deflection, torsion), method for fixing the spline shaft.
4. Predicting the service life, compared with the required service life.
5. Selecting a preload
6. Determining the accuracy
7. Selection according to the environment
