1、絲杠螺母的選材:45 鋼絲杠和 40Cr 鋼絲杠調質的熱處理工藝 調質是淬火加高溫回火的雙重熱處理, 其目的是使工件具有良好的綜合機械性能。調質鋼絲杠有碳素調質鋼和合金調質鋼二大類,不管是碳鋼還是合金鋼,其含 碳量控制比較嚴格。梯形絲杠原材料是通過模具拉光到所需要的中徑尺寸,二次冷拉形成表面硬度(0.5 毫米深)達(18°-21°)。
1. Material selection for lead screw nuts: The heat treatment process of quenching and tempering 45 steel wire and 40Cr steel wire is a dual heat treatment of quenching and high-temperature tempering, with the aim of ensuring that the workpiece has good comprehensive mechanical properties. There are two main types of quenched and tempered steel wire rods: carbon quenched and tempered steel and alloy quenched and tempered steel. Whether it is carbon steel or alloy steel, the carbon content control is relatively strict. The raw material of the trapezoidal screw is drawn to the required pitch diameter size through a mold, and the surface hardness (0.5 millimeters deep) is formed by secondary cold drawing, reaching (18 ° -21 °).
2、絲杠和螺母的公差配合,YF45Mnv鋼是85Kgf/mm(785N/mm)強度級別的一切削非調質鋼,其抗拉強度,疲勞性能,耐磨性能均優(yōu)于傳統(tǒng)常用的45調質鋼及40Cr鋼。鈦浩產(chǎn)品選用YF45Mnv鋼,也可選用45#調質鋼及40Cr鋼。
2. The tolerance fit of the screw and nut, YF45Mnv steel is a non quenched and tempered steel with a strength level of 85Kgf/mm (785N/mm). Its tensile strength, fatigue performance, and wear resistance are superior to the traditional commonly used 45 quenched and tempered steel and 40Cr steel. Titanium Hao products can use YF45Mnv steel, as well as 45 # quenched and tempered steel and 40Cr steel.
螺母材質選用,螺母材質傳統(tǒng)選用:錫青銅6-6-3及錫鋅青銅5-5-5。鈦浩產(chǎn)品選用鋁錫青銅ZCUA110Fe3,HRS~1000,摩擦系數(shù)小,無雜音,轉動靈活。
Nut material selection, traditional nut materials include tin bronze 6-6-3 and tin zinc bronze 5-5-5. Titanium Hao products use aluminum tin bronze ZCUA110Fe3, HRS~1000, with low friction coefficient, no noise, and flexible rotation.
3、絲杠螺母的潤滑:建議對梯型絲杠采用油潤滑, 特別是油池潤滑或滴油潤滑法更有效。油池潤滑是適當?shù)姆椒? 因為這種方法可以滿足苛刻的條件, 滴油潤滑適合于中低速度和中輕負荷的情況。
3. Lubrication of screw nuts: It is recommended to use oil lubrication for ladder type screws, especially for oil pool lubrication or drip lubrication, which is more effective. Oil pool lubrication is the most appropriate method because it can meet harsh conditions, and drip lubrication is suitable for medium to low speeds and medium to light loads.
梯形絲杠螺母是要求螺紋在運動中作精確移動的關鍵部件,主要采用合金鋼材加工,經(jīng)過熱處理加工,保證其優(yōu)良的機械性能,在制造過程中,粗精工序分開,有效保證零部件的應力合理分布,關鍵工序在恒溫車間加工,穩(wěn)定的溫度,保證高精度絲杠的全部指標符合有關驗收標準。
The trapezoidal screw nut is a key component that requires precise movement of the thread during movement. It is mainly made of high-quality alloy steel and processed through heat treatment to ensure its excellent mechanical properties. During the manufacturing process, the coarse and fine processes are separated to effectively ensure the reasonable distribution of stress in the components. The key process is processed in a constant temperature workshop, with stable temperature to ensure that all indicators of the high-precision screw meet relevant acceptance standards.
