1. 磨損：長期使用導致絲杠、螺母以及滾珠的磨損，影響傳動精度和效率。2. 卡死：可能由于雜質進入、潤滑不好的等原因造成滾珠或絲杠卡住不動。3.?回程誤差變大：即反向運動時出現較大偏差，通常也是磨損等因素導致。4. 噪聲異常：如出現異常的響聲，可能是部件損壞或配合不好的等引起。5. 絲杠彎曲變形：過度負載或受到沖擊等可能導致絲杠變形，影響正常運行。6. 密封失效：使灰塵、雜物等容易進入絲杠內部，引發一系列問題。7. 潤滑系統故障：如供油不足、油路堵塞等，導致潤滑不好。

　　1. Wear and tear: Long term use causes wear and tear on the screw, nut, and ball, affecting transmission accuracy and efficiency. 2. Stuck: The ball or screw may be stuck due to impurities entering or poor lubrication. 3. Increased return error: refers to the occurrence of significant deviation during reverse motion, which is usually caused by factors such as wear and tear. 4. Abnormal noise: If there is an abnormal sound, it may be caused by component damage or poor fit. 5. Bending and deformation of the lead screw: Excessive load or impact may cause deformation of the lead screw, affecting normal operation. 6. Sealing failure: making it easy for dust, debris, etc. to enter the interior of the screw, causing a series of problems. 7. Lubrication system malfunction: such as insufficient oil supply, blocked oil circuit, etc., resulting in poor lubrication.
