Cumulative pre error, similar approximation method. Cumulative representative lead error. The value obtained by deducting the cumulative base lead from the cumulative representative lead. Specification of precision ball screw Table 3.1 accumulative accumulation indicates wire error and allowable variation unit: effective thread tolerance and other part length accumulation meter has representative variation, represents variation range of thread part length and 2 radian variation unit: tolerance and other items axial clearance table 3.3 available combination of dimension and thread tolerance unit: axial clearance tolerance and other pre installed height can reach precision ball screw specification, shaft The external conventional combination material and heat treatment diameter and hardness of lead groove surface are key to the ball. Table 3.4 shows the conventional combination of shaft screw service life. Use material and heater diameter and. For other processed products listed in table 3.5 below, to meet the specifications, please consult. Proper hardness. Table 3.4 standard combination of shaft outer diameter and lead wire table 3.5 precision ball screw material and heating unit: handle shaft outer diameter, lead shaft nut is used in special environment, such as corrosive environment or vacuum, ball screw material made of special material, such as stainless steel, can also be provided on request. Please refer to the weldable range diagram of the overall shaft length. 3.2 shows the range of precision ball screws that can be produced over the entire shaft length. For those who show the range shown or the small ball screw, please consult. Figure 3.2 production range of total shaft length 19 precision ball screw specification 3.5. When preloaded, the ball contacts the preload engineering with the groove and preloads the torque ball screw at four points between the nut and the shaft. This method is Ball screw manufacturer There is usually a small gap, called a preloaded ball.
