挖掘機軸承內圈與軸,外圈與殼體孔都是緊配合,裝配套管端面應做成能同時壓緊挖掘機軸承內外套圈端面的圓環,或用一圓盤和裝配套管,使壓力同時傳到內外圈上,把挖掘機軸承壓入軸上和殼體中。此種安裝方法特別適用于能自動調心的向心球面軸承的安裝。

有百折不撓的信念的所支持的人的意志,比那些似乎是無敵的物質力量有更強大的威力。

Have a persistent belief supported by the people"s will, than those who appear to be unbeatable more powerful material force.

Excavator bearing inner ring and the shaft, the outer ring is tight fit with the shell holes, the assembling sleeve end should be made to compact excavators bearing inner and outer ring width at the same time the circle, or with a disc and assembling casing, make the pressure at the same time to the inside and outside the circle, the excavator bearing pressure into the shaft and housing. This installation method is particularly suited to automatically the centripetal spherical self-aligning bearing installation. Maintain proper oil temperature, the excavator hydraulic system of the general control working temperature between 30 ~ 80 advisable (dangerous temperature 100 or higher). Excavator hydraulic system oil temperature is too high will lead to: reduce oil viscosity, easy to cause leakage, efficiency decreases; Lubricating oil film strength is reduced, accelerated wear excavator; Carbide and silting crusts; The oil oxidation accelerated deterioration of oil; Oil seal, high pressure rubber hose, premature aging and so on. In order to avoid too high temperature: excavator don"t overload for a long time; Note don"t contaminated with oil radiator heat sink, to prevent the dust adhesion effect cooling effect; Keep enough oil for the oil circulation cooling; The hot summer months don"t work all day, at noon to avoid high temperature and time. The oil temperature too low, oil viscosity, liquidity is poor, resistance is big, the efficiency is low; When the oil temperature below 20 , a sharp turn easily damaged excavator hydraulic motors, valves, piping, etc. Working at this time need to be warm, excavator engine starting, idling running idle after 3 ~ 5 min, with medium speed throttle increase excavator engine speed, work device of the control handle to any action (such as excavator Zhang Dou) to limit position, keep 3 ~ 5 min to make hydraulic oil by raising the temperature of the overflow. If the oil temperature is lower need appropriate to increase the warming-up time operation.
