摘要： A seal for a joint subjected to oscillatory motion has a W-shaped seal ring which encompasses a backup ring partially. The W-shaped seal ring comprises a driving flange, a sealing flange and an intermediate hinge section connecting the two flanges.The backup ring is adapted to be fitted in the seal ring to force the driving flange into an interference fit with the counterbore walls so as to cause the driving torque to be applied through the seal ring. The seal ring is made of a tough abrasion-resistant material, while the backup ring is made of elastomeric material having excellent resiliency characteristics over a wide range of operating temperatures.The load exerted on the seal flange face is the sum of the compression forces of the backup ring and the seal ring and an internal pressure developed in the enclosed space.

摘要： Sealing apparatus which includes an elastic seal having end portions and at least one intermediate portion, all of such portions being interconnected yet axially spaced from each other whereby the seal is compressible. A projection is provided upon one end surface of the seal which is adapted to be disposed along the end portion of a bushing and extend within an annular space defined between the bushing and the link of the track shoe system, whereby penetration of earth and sand within a counterbored portion of the shoe system is positively prevented. An annular thrust ring may also be disposed within the counterbored portion of the system in a concentric manner with respect to the seal, the ring being disposed radially inwardly thereof, and in this manner, when large thrust forces are exerted upon the system, the thrust ring, interposed between the bushing and a bottom wall of the counterbored portion, will counteract the same.
摘要翻译：密封装置包括具有端部和至少一个中间部分的弹性密封件，所有这些部分彼此相互连接并且彼此轴向间隔开，从而密封件可压缩。在密封件的一个端面上设有突起，该突出部适于沿着衬套的端部设置并且在限定在履带板系统的衬套和连杆之间的环形空间内延伸，由此将砂土和/ 积极地防止了鞋系统的沉没部分。环形止推环也可以相对于密封件以同心的方式设置在系统的沉入部分内，该环被径向向内设置，并且以这种方式，当大的推力施加在系统上时，推力插入衬套和沉入部分的底壁之间的环将抵消它。

摘要： A high toughness and wear-resistance steel consisting, by weight percent based R.sub.weight of the steel, of 0.25 to 0.38 of carbon, 1.60 to 2.60 of silicon, 0-0.8 of manganese, 0-0.3 of phosphorus, 0-0.3 of sulphur, 3.0 to 6.0 of chromium and the balance of Fe. The steel is mainly used as an excavating tool edge material for construction machines.
摘要翻译：一种高韧性和耐磨钢，以重量百分比为基准的钢重量为0.25至0.38的碳，1.60至2.60的硅，0-0.8的锰，0-0.3的磷，0-0.3的硫， 3.0〜6.0的铬，余量为Fe。钢主要用作施工机械的挖掘工具边缘材料。
