Ball screw nut ball screw nut mounting method used to bear only axial load, radial force, moment will make contact with the surface of the ball screw nut additional stress load Guangzhou ball screw, which may cause screw permanent damage. Correct installation is the effective maintenance of the premises. So Ball supplies ball screw nut attached to the machine, you should note the following: 1) the screw axis must be parallel to the axis ancillary rail, machine ends with the nut bearing seat must be three a line. 2) When installing nuts, as close to the support bearing. 3) Install the supporting bearing ball screw nut is installed as close to the site. 4) When the ball screw is mounted to the machine, do not remove the nut from the screw to. The main parameters of the thread 1) the outer diameter d (large diameter) (D) - and coincide with the external thread crest diameter imaginary cylindrical surface - also known as nominal diameter 2) internal diameter (small diameter) d1 (D1) - outer coincide with the end of the thread of an imaginary cylindrical surface diameter, as dangerous in the strength calculation section calculates a diameter of 3) in diameter d2-- imaginary cylindrical surface at a diameter equal to the width between the teeth and tooth thickness in the axial cross-section, approximately equal The average diameter of the threaded d2≈0.5 (d + d1) 4) pitch P-- two adjacent teeth on the diameter of the cylindrical surface of the bus corresponding axial distance between two points 5) lead (S) - the same helix the axial distance between two adjacent teeth on the ball screw machining correspondence between two points on the diameter of the cylindrical surface of the bus, ball screw, Korea and Taiwan transmission machinery provided by the Dongguan City, Transmission Machinery Co., Ltd. of Korea and Taiwan.
