B+S V型密封TWVA01700-N6T50產(chǎn)品介紹
V形密封圈是一種獨(dú)特的旋轉(zhuǎn)軸全橡膠密封。
它由FORSHEDA AB于1960開發(fā)，已被原始設(shè)備制造商和全球替代市場廣泛應(yīng)用。
V形密封圈是防止灰塵、灰塵、水或這些介質(zhì)組合進(jìn)入的理想密封件，同時(shí)能有效地保留潤滑脂。憑借其獨(dú)特的設(shè)計(jì)和性能，V型環(huán)可用于多種軸承類型。它也可用作二次密封，以保護(hù)在惡劣環(huán)境中性能不佳的一次密封。
說明和優(yōu)點(diǎn)
V型環(huán)通常被拉伸并直接安裝在軸上，通過橡膠體的固有張力將其固定到位。它與軸一起旋轉(zhuǎn)，并與垂直于軸垂直的固定面軸向密封。背面可以是軸承的側(cè)壁或墊圈、沖壓件、軸承座，甚至是油封的金屬外殼。密封唇是柔性的，僅對相對面施加相對較輕的接觸壓力，但仍足以保持密封功能。低接觸壓力（隨安裝寬度而變化）允許密封在許多應(yīng)用中干燥運(yùn)行。
由于離心力的影響，唇板的接觸壓力隨著轉(zhuǎn)速的增加而減小。這意味著摩擦損失和熱量保持在最低限度，從而產(chǎn)生優(yōu)異的磨損特性和延長的密封壽命。一旦分離摩擦力被克服，摩擦力就會(huì)穩(wěn)定地減小，直到大約10-15 m/s的范圍內(nèi)，這時(shí)摩擦力會(huì)迅速減小。在15-20 m/s范圍內(nèi)，摩擦力減小到零。然后，V形環(huán)用作間隙密封和導(dǎo)向器。
柔性唇和鉸鏈允許V形環(huán)即使在一定量的跑偏、偏心和軸不對中的情況下也能起作用。請與我們當(dāng)?shù)氐腡SS公司聯(lián)系，獲取有關(guān)這些和其他應(yīng)用程序問題的建議。
V型環(huán)完全由橡膠制成，沒有織物或金屬板加固。因此，它們特別容易安裝。V形環(huán)可以拉伸，根據(jù)尺寸，安裝在法蘭、滑輪和軸承座上，無需昂貴的拆卸。對于較大的尺寸，它們甚至可以作為切割環(huán)提供，并通過現(xiàn)場硫化連接。
The V-RING is a unique all-rubber seal for rotary shafts.
Developed in the 1960’s by FORSHEDA AB, it has been used successfully by OEMs and on the replacement market world wide in a broad range of applications.
The V—Ring is the perfect seal to prevent the ingress of dirt,dust, water or combinations of these media while positively retaining grease. With its unique design and performance the V—Ring can be used with a wide range of bearing types. It can also be used as a secondary seal to protect primary seals that do not perform well in hostile environments.
Description and advantages
The V—Ring is normally stretched and mounted directly on the shaft, where it is held in position by the inherent tension of the rubber body. It rotates with the shaft and seals axially against a stationary counterface, perpendicular to the shaft. The counterface can be the side wall of a bearing or a washer, stamping, bearing housing, or even the metal case of an oil seal. The sealing lip is flexible and applies only a relatively light contact pressure against the counter-face and yet is still sufficient to maintain the sealing function. The low contact pressure (that varies with the fitted width) allows the seal to run dry in many applications.
Due to influence of the centrifugal force, the contact pressure of the lip decreases with increased speed. This means that frictional losses and heat are kept to a minimum, resulting in excellent wear characteristics and extended seal life. Once breakaway friction is overcome,the friction reduce steadily until around the 10 - 15 m/s range, when it reduces quite quickly. In the 15 - 20 m/s range the friction reduces to zero. The V—Ring then serves as a clearance seal and deflector.
The flexible lip and hinge allow the V—Ring to function even in the presence of a certain amount of run-out, eccentricity and shaft misalignment. Contact our local TSS company for advice on these and other application issues.
V—Rings are made entirely of rubber without fabric or sheet metal reinforcement. They are, therefore, particularly easy to install. V—Rings can be stretched and, depending on size,installed over flanges, pulleys and bearing housings without costly dismantling. For larger sizes they can even be supplied as cut rings and joined by vulcanisation on site.
