ball splineThere are three rows of load-bearing steel balls on the outer diameter of the spline shaft, and the Gothic tooth design allows the three rows of steel balls to simultaneously withstand clockwise and counterclockwise torque, thereby increasing their service life and rigidity. Each steel ball column continuously circulates through a special synthetic resin cycler installed inside the keyway cap, so even if the keyway shaft is pulled out of the keyway cap, the steel balls will not fall off.
Product characteristics
High load capacity
Due to the special processing of the rolling groove of the steel ball, the groove adopts a Gothic tooth shape with a contact angle of 30 °, which has a large load capacity in both radial and torque directions.
The rotational clearance is' zero '
By applying pre pressure to the angular contact structure, the clearance in the rotation direction can be zero, thereby improving rigidity.
rigidity
Due to the large contact angle, applying appropriate preload depending on the situation can achieve high torque rigidity and torque rigidity.
Steel ball retaining type
Due to the use of a cycler, even if the spline shaft is extracted from the keycap, the steel ball will not fall off.
application
Industrial robots, handling equipment, automatic winding machines, ATC automatic tool changing devices, etc.
