High-precision ball runner block BSHP

Rexroth block Material specifications_00

New entry-zone geometry for ball runner block in high-precision version The ball runner blocks in high-precision version comprise of an innovative entry zone. The steel bearing plates are not supported by the ball runner block in the end area and can therefore deform elastically. The entry zone adjusts itself individually to the current operating load of the ball runner block. I.e. the balls run smoothly into the bearing zone without loading pulsations

Rexroth

1) Ball runner block

2) Steel bearing plate

3) Ball guide rail

4) – 7) Balls

Ball entry

▶ The balls (4) are guided up to the start of the entry zone via the roller deflection.

▶ The ball (5) can enter without load.

▶ The ball (6) elastically deforms the end of the steel bearing plate (2). This deformation results from the total yielding of the ball deformation and the deformation of the free ends of the steel bearing plates.

▶ If the distance between the steel bearing plate and the ball guide rail (3) is smaller than the ball diameter, the ball is put under load (preload) slowly and evenly.

▶ The preload is increased harmonically until the ball (7) has reached its maximum preload.

Innovative solutions by Rexroth:

The load-dependent entry zone The functionality of the entry zone is decisive. The steel bearing plates are manufactured with such precision that they deflect by the ideal amount according to the load. Thus, the balls can enter particularly smoothly. Due to the precise manufacture of the steel bearing plates, they are only deformed by an entering ball to such an extent that the following ball can run in without load. The balls thus no longer enter the load-bearing zone through a fixed entry zone, rather transition smoothly on a tangential, ideally angled elastic line into the load-bearing zone. The smooth entry of the balls and the continuous adaptation of the entry zone to the load represent the most decisive benefits of the high-precision ball runner blocks.
