When checking, screw speed = input speed / i, where i is the lift ratio. Ball Specifications A-type structure of the standard ball screw sizes and carrying capacity in the following table, the data carrying capacity of other pitch and provided as needed. For ball screw pitch and the other carrying capacity can choose B-type structure. Ball screw efficiency: η90% CS2.5, trapezoidal screw 14 × 4 lifting force and lifting speed table CS5 CS worm screw lift, trapezoidal screw 18 × 4 lifting force and lifting speed screw Sewing Table 1. Protection cover: Round screw shields are stamped by the wafer sewn into, two adjacent inner edge, two outer sewn together by sewing can achieve stable and secure good shape in the horizontal direction . Material according to different working environments have a wide selection 2. screw shield: one is supporting rims screw shields, using a variety of fabrics such CS turbine shroud screw lift, there are stiff wire ring support in high temperature 110 ℃, low temperature between -40 ℃ to work properly. Can effectively dustproof, waterproof, anti-oil, anti-emulsion and chemicals, neat appearance, easily deformed square box screw lift CS, based on its tight, strong, and can be used for this cover numerous mechanical ventilation, dust and other small CS screw lift, Kai brand CS screw lift (certified), CS provided by Tai Machinery Co., Ltd.
