Antibacklash Ballscrew SFU1610-19.69''(500mm)
|
The rotary motion is driven by the feed motor,
into linear motion of the carriage or as a platform of ding. An arc spiral
groove is disposed on the lead screw and the nut, and when they are sheathed
together, a spiral raceway is formed and a ball bearing is arranged in the
raceway. When the lead screw rotates relative to the nut, the nut produces an
axial shift, while the ball rolls along the raceway. The two ends of the spiral
groove of the nut are connected with a bead returning device, so that the ball
can move round and round again, and the two ends of the pipe also play the role
of blocking beads, so as to prevent the ball falling out along the raceway.

Application:
Ball screws are used in aircraft and missiles to move control surfaces,
especially for electric fly by wire, and in automobile power steering to
translate rotary motion from an electric motor to axial motion of the steering
rack. Because it's small friction drag,They are also used in machine tools,
robots and precision assembly equipment. High precision ball screws are used in
steppers for semiconductor manufacturing.
Features:
1.A small friction loss, high transmission efficiency
There are a lot of balls rolling movement between the screw shaft and ball screw
nut, they are able to get a higher efficiency of movement. Helpful in saving.
2.High-precision
Ball screw was manufactured by the world's highest level mechanical equipment,
especially in the grinding, assembly, inspection of the process plant
environment, temperature and humidity were strictly controlled, because of the
sound quality management system so that the accuracy can be fully guaranteed.
3.High speed feed and Micro-feed may
Ball screw used the ball movement, so the starting torque is very small, It's
doesn't appear as a sliding motion creeping phenomenon , can ensure accurate
micro-feed.
4.Axial stiffness high
Ball screw can be adding preloading, The axial clearance can be achieve negative
due to the pre-pressure , then get a higher rigidity.
5.Due to their high efficiency,precision ball screw assemblies are in principle
not self-locking.
