Taiwan TBI ball screw SCI series has the characteristics of long life, high precision, low calorific value, high speed, high rigidity, low noise, high wear resistance, etc. In order to meet the performance requirements, the chemical composition uniformity of steel, non-metallic inclusions The content and type of carbides, particle size and distribution of carbides, and decarburization are strictly required.
The SCI ball screw is fixedly installed at both ends, but how to control its pretightening force?
First consider the elongation of temperature rise (it can be roughly calculated as 0.001mm of elongation per meter of temperature rise of 1 degree), then calculate the axial elastic deformation of the diameter of the specification to the tensile force, and then calculate the size of the end thread and the locking method The relationship between the axial tension and the tightening torque is obtained.
This kind of ball screw pair is gapless (or pre-tightened ball screw pair), after pre-stretching (that is, adding pre-tightening force), elastic deformation between the screw and the nut, reducing the ball body and eliminating the axial gap : The ball screw pair used for precise positioning and can indirectly measure the axial travel according to the rotation angle and lead (transport ball screw) may not be preloaded.
Generally, the measurement of the axial stroke is completed by a measuring device that has nothing to do with the rotation angle and lead of the ball screw pair. To increase the rigidity of the ball screw pair, the positioning ball screw must be preloaded to achieve higher accuracy.
TBI ball screw C7 grade is in stock, welcome new and old customers and friends to inquire and order.
