How much do you know about the ball screw jack
Ball Screw Jacks use
a ball screw and nut made from hardened alloy steel with hardened
bearing balls carrying the load between nut and screw.This rolling
action reduces friction between the nut and the screw permitting smooth
and efficient movement of the load.
The difference between a ball screw jack and a machine screw jack
is that it uses a high precision ball screw. The ball screw can be
used in a wide range of applications. The ball screw has high precision,
low pollution, long life and high speed forward reversal. Therefore, it
has become a standard accessory in the field of precision machinery in
recent years. The ball screw is used on the lift to help the screw jack
have higher positioning accuracy, lower noise, faster speed and a
significant increase in efficiency. Therefore, the ball screw jack is
more suitable in high-speed high-frequency environments.
The
ball screw jack, whose thermal expansion prone to cause a decrease in
accuracy have always been a question for customers. In fact, if you want
to pay attention to this situation, we must note that , not only the
heat caused by ball friction, but also the operation of mechanical parts
such as motors or gear boxes. Therefore, when using ball screw jack, we
must take all the heat sources into account and calculate a better
installation position so that the screw jack can operate more
accurately.
If
the working temperature is high, a separate cooling system can be
loaded on the ball screw. Cooling down by cold air or oil mist, but air
cooling is recommended because it will be more energy efficient.
The
addition and replacement of ball screw jack grease is also a special
consideration. Usually, the lubrication of the ball screw jack includes
grease lubrication and oil lubrication, because the inside of the
housing needs to be filled with grease to complete the lubrication, and
the screw requires oil lubrication to be added inside the nut. So when
you change, don’t forget the lubrication of the screw nut.
Above are some explanations and precautions for the ball screw jack from Lude Transmission.
Hope pay more attention when purchasing and using, which can extend the
service life and improve the efficiency of the screw jack .
