升降機廠家http://www.jntr168.com/介紹隨著機械產(chǎn)品日趨高速化、多樣化,對作為重要機械旋轉(zhuǎn)件的滾動軸承要求也愈來愈高,為進一步提高滾動軸承在升降機上的應(yīng)用水平,人們對運轉(zhuǎn)中軸承因負(fù)荷不同、滾動體與滾道之間產(chǎn)生滑動而造成擦傷的原因越來越重視。尤其是在升降機械裝配時,應(yīng)根據(jù)軸承的使用情況,對軸承的預(yù)緊負(fù)荷力的大小進行選擇,以優(yōu)化軸承的游隙。
Lift manufacturers introduced products with increasingly high-speed machinery, diversified, of an important piece of Rolling mechanical rotation requires higher and higher, in order to further improve the application of the rolling bearing on the elevator level, people running in different load bearing due to rolling slippage between the body and the raceway and causes abrasions of more attention. Especially when lifting machinery assembly, should be based on the use of bearing preload to the size of the load bearing force can be selected to optimize the bearing clearance.
升降機廠家分析滾動軸承的游隙分徑向游隙產(chǎn)和軸向游隙產(chǎn)兩種,它們分別表示軸承內(nèi)外圈,沿徑向或軸向的最大相對位移量。軸承標(biāo)準(zhǔn)中將徑向游隙分為基本游隙組和輔助游隙組,應(yīng)優(yōu)先選用基本游隙組,軸向游隙可由徑向游隙按一 定的關(guān)系換算得到。對內(nèi)外套圈可分離的軸承,其游隙須由安裝確定。
Lift manufacturers analysis of rolling bearing clearance radial clearance capacity points and two axial clearance capacity, which represent the bearing inner ring, a radial or axial maximum amount of relative displacement. Standard radial clearance in the bearing clearance group is divided into basic and secondary clearance group, preference should be given basic clearance group, axial clearance radial clearance by a certain relationship Converted. Separable inner and outer rings of the bearings, the clearance shall be installed OK.
升降機廠家http://www.jntr168.com/談到在無負(fù)荷的情況下,軸承內(nèi)、外滾道間所能移動的最大距離即為軸承的游隙,在大多數(shù)情況下,滾動軸承在工作過程中應(yīng)允許有適當(dāng)?shù)挠蜗叮蜗哆^大,同時承受載荷的滾動體數(shù)目減少,易使?jié)L動體與套圈產(chǎn)生彈性變形,降低軸承壽命和旋轉(zhuǎn)精度,產(chǎn)生徑向跳動,從而引起振動和噪聲;游隙過小,則工作時阻力增大,軸承容易磨損,壽命縮短。
Lift manufacturers Speaking at no load, the bearing, the maximum distance between the outer race track can move is bearing clearance, in most cases, the rolling bearing during operation should allow adequate clearance, clearance is too large, while reducing the number of rolling elements bear the load, easy to make rolling ring elastically deformed, reduce bearing life and rotational accuracy, radial runout, causing vibration and noise; clearance is too small, the work when the resistance increases, the bearing is easy to wear and shortened life expectancy.
