游隙或預(yù)負(fù)荷的選擇,取決于升降機(jī)對軸承布局的性能和運(yùn)轉(zhuǎn)條件的要求。下面濟(jì)南天銳升降機(jī)械的專家給大家分析一下角接觸球軸承和圓錐滾子軸承的軸承布局的內(nèi)部游隙調(diào)整。
1、升降平臺上軸承在安裝時要達(dá)到適當(dāng)?shù)挠蜗吨?,可根?jù)軸承的負(fù)荷和工作溫度狀況來確定。根據(jù)軸承的尺寸和布局、軸和軸承箱的制造材料以及兩個軸承間的距離,安裝時獲得的初始游隙在實(shí)際運(yùn)轉(zhuǎn)中可能會變小或變大。
Lift manufacturers introduced bearing on the lift platform during installation to achieve proper clearance values may be determined according to the load and operating temperature condition of the bearing. Size and layout depending on the distance of bearings, shaft and housing materials of construction and two bearings between the initial clearance obtained when installed in the actual operation may be smaller or larger.
2、內(nèi)外圈的溫差熱膨脹會造成運(yùn)轉(zhuǎn)中游隙的縮小,因此初始游隙必須相當(dāng)大,才能避免軸承變形及其不利后果。用輪轂上的千分表,檢查輪轂軸承布局的設(shè)定軸向游隙。在調(diào)整圓錐滾進(jìn)口軸承和測量游隙時,
軸或軸承箱需朝不同方向旋轉(zhuǎn)數(shù)周,以確保滾珠端部與內(nèi)圈上的導(dǎo)緣有適當(dāng)?shù)慕佑|。如果接觸不當(dāng),測量結(jié)果就不精確,就不能達(dá)到預(yù)期的調(diào)整目的。
Lift manufacturers differential thermal expansion comes to inner and outer rings will cause operating midstream gap narrowed, so the initial clearance must be quite large in order to avoid bearing deformation and its adverse consequences. Dial gauge on the hub, check the hub bearing arrangement set axial clearance. When adjusting tapered roller bearings and measuring the clearance, shaft or bearing housing need in different directions of rotation for several weeks to ensure that the leading edge of the inner end portion of the ball on the appropriate contacts. If the contact properly, measurement is not accurate, it can not achieve the intended purpose of the adjustment.
