滑动轴承的承载能力大、耐磨、运转稳定可靠、制造成本低、工作寿命长,但滑动轴承装配比较麻烦,如果轴颈与轴承装配不当,钨金瓦的刮研达不到要求,会使轴承工作时过热(除润滑不良等原因外),甚至钨金层熔化,造成机械事故。一、轴颈与轴承下瓦工作区的接触弧面和侧间隙 1—轴颈;2—瓦口斜面三角区; 3—钨金层;4—瓦衬见图1,轴颈与滑动轴承下瓦工作区的接触要求如下: 1、接触斑点均匀,颜色清亮。斑点大小以2～3mm为宜。斑点不应连成一片呈块状或线状,在下瓦工作区任一小面积范围内,能清楚地数出斑点的个数。应满足在接触弧面内每
Slide bearing bearing capacity, wear-resistant, stable and reliable operation, low manufacturing costs, long working life, but the sliding bearing assembly is too much trouble, if the journal and bearing assembly improper, tungsten alloy tile scratch research and requirements, will make Bearing overheating (except for poor lubrication and other reasons), and even tungsten layer melting, resulting in mechanical accidents. First, the bearing neck and bearing the lower contact area of the arc and the side of the gap 1-journal; 2- Waiguchi bevel triangular area; 3-tungsten layer; 4-tile lining see Figure 1, journal and sliding bearing Workspace contact requirements are as follows: 1, contact spots evenly, the color is clear. Spot size to 2 ~ 3mm is appropriate. Spots should not be linked into a block or linear, in any area of the work area of the tile, the number of spots can be clearly identified. Should be satisfied in the contact arc every
