摘要： A dust seal is provided with a tubular fitting portion, a bush end surface abutting portion, a lip portion and a sealing projection integrally formed. The sealing projection is formed to project in an axially opposite direction to the lip portion from a radial inner section of the bush end surface abutting portion and abuts against a chamfered portion of a bush in such a manner as to overlap the chamfered portion. Therefore, at the time of supplying lubricant between the bush and a connecting pin, the sealing projection can prevent a part of the lubricant from entering between an end surface of the bush and the bush end surface abutting portion of the dust seal to maintain a sealed state therebetween. In consequence, the dust seal can be stably held on the inner peripheral side of a boss member, preventing the pulling-out of the dust seal.

摘要： An oil-impregnated sintered sliding bearing formed of a porous iron-based sintered alloy with quenched structure and receiving a high surface pressure capable of reducing the number of finishing steps by cutting and grinding and providing a bearing performance equivalent to or higher than that of conventional bearings, wherein a plurality of ridge-and-groove lines having a height difference of 2 to 12.5 μm and extending in circumferential direction are axially arranged in parallel with each other by boring the bearing surface thereof to form a wavy surface in axial direction, and the portion thereof deeper by 10 to 60 μm from the outer layer of the bearing surface is formed dense to seal surface pores so as to reduce the pores opening to the outer surface to 1 to 10 percent by area, whereby the bearing can be used at a surface pressure of 6 kgf/mm2 (58.5 MPa) or higher and a sliding speed of 2 to 5 cm/s.
摘要翻译：一种浸油烧结滑动轴承，由具有淬火结构的多孔铁基烧结合金形成，并具有能够通过切割和研磨减少精加工步骤的数量的高表面压力，并提供与常规相当或更高的轴承性能轴承，其中通过对其轴承表面进行钻孔而在轴向方向上彼此平行地布置具有2至12.5μm的高差为2至12.5μm并沿圆周方向延伸的多个脊沟槽线，以在轴向方向上形成波浪形表面，并且从支承面的外层更深10〜60μm的部分形成为致密的，以密封表面孔，以便将通过外表面打开的孔减少到1至10％的面积，由此轴承可以用于表面压力为6kgf / mm 2（58.5MPa）以上，滑动速度为2〜5cm / s。

摘要： A seal device (31) for a bearing system (21) is constituted by first and second seal rings (32) and (35). The first seal ring (32) is constituted by a lip seal (33) having a lip portion (33B) in sliding contact with an end face (23B) of a bush (23) which is fitted on a joint shaft (26), and a slide tube (34) having a seal surface (34C) on an end face at an axial end away from the lip portion (33B) which is formed integrally with a tubular body portion (33A) of the lip seal (33). The second seal ring (35) is fixedly fitted in a boss (22) radially on the outer side of the first seal ring (32), and provided with a seal surface (35D) on the inner side of an annular inward collar portion (35C) for sliding contact with the seal surface (34C) of the slide tube (34).
