Taiwan TBI Ball Screw SFS3210(ball screw 32mm,ball screw 10mm pitch)
Ball Screw is made of screw and ball nut . It's function is to turn the rotary
motion into linear motion.,which is a future extension and development of ball
screw. The significance of the development is to move into a rolling bearing
from sliding action. With little frication, Ball Screw are widely used into
various industrial equipment and precision instruments.
1.Machine tools
2.Industrial machinery Printing, paper-processing, automatic machines, textiles, etc.
3.Electronic machinery Robot, measuring instruments, medical equipment, X-Y table, factory automation equipment, etc.
4.Transport machinery Material handling equipment, nuclear reactor-actuator, etc.
5.Aircraft applications: aircraft flaps, actuators, airport loading equipment, etc.

Ball screw, free-rolling ball force and motion passed between the screw and nut, this drive instead of a direct role in the way the traditional threaded screw vice screw and nut minimal rolling
friction instead of sliding friction of the conventional screw, and greatly reduces the friction so that the ball screw transmission efficiency greatly improved. Precision ball screw transmission
efficiency reaches above 90%, the traditional sliding screw in most cases only about 20-30%, and further, the driving torque of the whole transmission vice reduced to about 1/3 of the sliding screw
vice. Precision ball screw series of testing equipment and quality control process to ensure the realization of high transmission efficiency.
It is precisely because the ball screw transmission efficiency of 90% or more, and thus the heat generation rate can be greatly reduced. The superior precision ball screw ball track surface
quality, as well as strict size ball contact friction between the ball and the track to a minimum.
Small temperature rise in the movement of the ball screw, and stretched to compensate for thermal elongation and pretension to eliminate the use of axial and other measures to eliminate axial
clearance, pre-stretch of the screw and the equipment for high positioning accuracy and repetition positioning accuracy.
After a well-designed, precision ball screw friction is extremely small, allows the machine to run at high speed, to meet the needs of today's overloaded high-speed.
The preload i.e. to eliminate the axial clearance between the screw and nut, it is necessary the use of ball screw. Although doing little to improve their friction the available transmission
desired high rigidity while significantly reduce the axial backhaul clearance. Special precision ball screw design and operating process to meet customer requirements, provide accurate pretension
ball screw stiffness.
based on the above characteristics, and the ball screw is not the viscous friction of the sliding screw, eliminating crawling phenomenon may occur in the transmission process, precision ball
screw can be smoothly realized two transmission mode - the rotary motion into linear motion or linear motion into rotary motion, in which power is transmitted at the same time. As shown.
Way: screw do the active rotary motion to linear motion drive nut.
Second way: Nuts do active rotational movement of the drive screw linear motion.
Precision ball screw on the the screw track shape accuracy, surface hardness, and the choice of materials to be strictly controlled, much higher than the design life expectancy in the proper use
and maintenance conditions, the actual life of the ball screw.
The combination of the high efficiency of the entire ball screw drive starting torque is small, so that the input power of the system to reduce.
As the smooth operation, the high response (high rigidity), and manufacturing consistency, using the obtained good synchronized action, in the program of multiple sets of ball screw drive the
same device or a plurality of identical components.
In most cases, as long as good general lubrication and dust.
Users of precision ball screw can be directly involved in the whole process of the design of the screw.
