What is the purpose of lead screw preloading?

用油脂潤滑時(shí)，是非常易粘附在螺旋滾道外表，堅(jiān)持的潤滑情況。讓其在作業(yè)的時(shí)分，可以有用減少運(yùn)動部件的磨損及解決噪音問題，具有的抗磨抗壓才華及高低溫功用安穩(wěn)。雖然留意滾珠絲杠副保涂層中不會出現(xiàn)碎屑和空位，但要小現(xiàn)已證明空位對系統(tǒng)功用沒有影響。

When lubricating with grease, it is very easy to adhere to the surface of the spiral raceway and adhere to the lubrication. During operation, it can effectively reduce the wear of moving parts and solve the noise problem. It has the ability of anti-wear and compression and the function of high and low temperature. Although it is noted that there will be no debris and vacancy in the protective coating of the ball screw pair, it should be small. It has been proved that the vacancy has no effect on the function of the system.

轉(zhuǎn)移只要螺母，滾珠絲杠螺母就可以在整個(gè)組件的運(yùn)用壽數(shù)期間繼續(xù)運(yùn)轉(zhuǎn)定期穿過涂層區(qū)域。滑劑，雖然是固體，在流體劑中也具有一些“擴(kuò)散”才華。涂層螺絲供應(yīng)大度的自滑，不該額定滑或在或許存在油或其他潤滑劑污染的環(huán)境中運(yùn)用。鋼制螺絲由合金鋼制成，通過熱處理后具有很高的抗拉強(qiáng)度。

As long as the nut is transferred, the ball screw nut can continue to operate throughout the service life of the assembly and pass through the coating area regularly. Slip agent, although solid, also has some "diffusion" talent in fluid agent. Coated screws provide generous self slip and should not be rated for slip or used in environments that may be contaminated with oil or other lubricants. Steel screws are made of alloy steel and have high tensile strength after heat treatment.

不銹鋼內(nèi)六角螺釘一般由302或304制成，不進(jìn)行熱處理。螺釘有多種類型。這些螺釘?shù)囊?guī)劃材料和螺紋類型根據(jù)其用途和預(yù)期聯(lián)接在一同的材料而有所不同。機(jī)器螺釘是常見和通用類型的螺釘，規(guī)劃有直的，非錐形的柄和鈍端。鈑金螺釘，也稱為自攻螺釘，用于功用和規(guī)劃。根據(jù)金屬的需求，它們的頭部可所以扁平，橢圓形或六角形。

Stainless steel hexagon socket screws are generally made of 302 or 304 without heat treatment. There are many types of screws. The planned material and thread type of these screws vary according to their purpose and the material expected to be connected together. Machine screw is a common and universal type of screw with straight, non conical shank and blunt end. Sheet metal screws, also known as self tapping screws, are used for function and planning. According to the demand of metal, their heads can be flat, oval or hexagonal.

滾珠絲杠

Ball screw

可是如何在不犧行程長度的情況下減少滾珠絲杠的無支撐長度？長途旅行與高速：你可以有兩者滾珠絲杠支撐可以處理這種長度速度的窘境。這些浮動支撐（一般用于2,4或6組）位于滾珠螺母的一側(cè)，并以容許它們在滾珠絲杠螺母的一側(cè)延伸到持平間隔的辦法聯(lián)接，如螺母沿相反方向移動，按比例減小無支撐長度。

But how to reduce the unsupported length of the ball screw without sacrificing the stroke length? Long distance travel and high speed: you can have two ball screw supports to deal with the dilemma of length and speed. These floating supports (generally used for groups 2, 4 or 6) are located on one side of the ball nut and connected by allowing them to extend to a flat interval on one side of the ball screw nut. If the nut moves in the opposite direction, the unsupported length is reduced proportionally.

在滾珠螺母跋涉的方向上，支撐件在螺釘?shù)慕Y(jié)尾堆疊以供應(yīng)對行程的小攪擾。根據(jù)臨界速度方程，添加一組滾珠絲杠支撐（滾珠螺母兩邊各一個(gè)支撐）將使螺桿的臨界速高四！金屬制造和木匠中的切開，布線和其他操作是常見的運(yùn)用用于滾珠絲杠支撐，由于它們需求高推力和的定位精度，一同速移動長間隔。

In the direction of travel of the ball nut, the supports are stacked at the end of the screw to provide small disturbance to the stroke. According to the critical speed equation, adding a set of ball screw supports (one support on both sides of the ball nut) will increase the critical speed of the screw by four! Cutting, wiring and other operations are common in metal manufacturing and carpentry. They are used for ball screw support. Because they require high thrust and positioning accuracy, they move at the same speed for long intervals.

除了自潤滑縮醛螺母材料，供應(yīng)種定制復(fù)合Ke復(fù)合聚合物。聚合物是一種高材料系列，具有色的磨性和本錢通過注塑成型供應(yīng)規(guī)劃勢。聚合物供應(yīng)種各樣的機(jī)械，熱和電功用，并與許多化學(xué)品兼容環(huán)境條件。合聚合物是大多數(shù)螺母的選擇導(dǎo)軌和軸襯套，的標(biāo)準(zhǔn)材料襯套和端部支撐

In addition to self-lubricating acetal nut materials, a custom composite Ke composite polymer is supplied. Polymer is a kind of high material series with color abrasiveness and cost. It is supplied through injection molding. Polymers supply a wide variety of mechanical, thermal and electrical functions and are compatible with many chemicals and environmental conditions. Synthetic polymer is the choice for most nuts, guide rail and shaft bushing, standard material bushing and end support
