摘要： A two-member connection structure is provided with a boom to be arranged on a hydraulic excavator, an arm arranged inboard the boom, outboard bushings and inboard bushings press-fit in pin holes of the boom and arm, respectively. A connector pin is inserted in holes of the outboard bushings and holes of the inboard bushings to connect the boom and arm as two members for relative pivotal movement. Flange portions are integrally arranged on opposite end portions of the connector pin, respectively, to restrict slip-out of the connector pin. The connector pin is arranged rotatably relative to both of the outboard bushings and the inboard bushings, and the flange portions are arranged slidably relative to outboard end faces of the corresponding outboard bushings without being prevented from rotation relative to the boom.

摘要： A parallel support member is constituted by a pair of links that are respectively arranged on the left and right sides of a second boom. These links are connected between a first boom and a third boom. Thus, the second boom is moved to the left or right side by an offset cylinder. In this case, when one of the links pulls the third boom the third boom, an arm, and a bucket can be moved toward the left or right side of a vehicle body to be parallel to the first boom. At this time, the links accept a force exerted in the pulling direction, but need not receive a force exerted in the compression direction, so that the cross sectional areas, the weights of these links can be reduced.

摘要： In a slide bearing assembly 12 comprising a shaft 22 and a bushing 16 which is made of a porous sintered material having a large number of pores 25, the bushing 16 is impregnated with a lubricant 24 containing 2.0 to 30 wt % of solid lubricating fine particles 26 made of at least one selected from among MoS2, WS2, and hexagonal BN, and the shaft 22 and the bushing 16 are used at surface pressure not lower than 6 Kgf/mm2 and sliding speed in the range of 2 to 5 cm/sec. This realizes prolongation of a period during which sliding operation can be continued in an oilless self-lubricating state even under a situation of sliding at a very low speed or angular motion in a very small stroke.

摘要： Protective projections (26D) which are provided on cylinder mounting brackets (26) of a cargo handling tool (21) are arranged to project toward a vehicle body (2) from behind the cargo handling tool (21). When the vehicle body (2) is driven in reverse direction with a boom (12) in a folded position on the side of the ground, the protective projections (26D) are collided against obstacles (A) on the ground prior to a rod (27C) of a fork cylinder (27) if the lower side (2A) of the vehicle body (2) has passed over and clear of the obstacles (A). Thus, the protective projections (26D) function to protect the fork cylinder rod (27C) of the fork cylinder (27) against direct collision against obstacles (A) on the ground.

摘要： In this grease composition, a grease produced by mixing at least one base oil selected from a mineral oil-type lubricant base oil, a synthetic lubricant base oil, and a biodegradable lubricant base oil with a thickener is compounded with a wax and water, and an additive such as a surfactant and a defoamer is optionally compounded therewith. A soap containing a calcium sulfonate complex is used as the thickener. A carnauba wax is preferably used as the wax. Since this grease composition is mainly composed of a grease and a wax, the grease composition extremely facilities its removal operation after application, is environmentally friendly, and has extremely excellent anti-corrosion performance. When the grease composition is used by being applied to a base material of an object to be welded, an effect of preventing the adhesion of welding spatters can be obtained.

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.
摘要翻译：防尘密封件设置有一体形成的管状装配部，衬套端面抵接部，唇部和密封突起。所述密封突起形成为从所述衬套端面抵接部的径向内侧部朝向所述唇部的轴向相反的方向突出，并以与所述倒角部重叠的方式与所述衬套的倒角部抵接。因此，在衬套和连接销之间供给润滑剂时，密封突起可以防止一部分润滑剂进入衬套的端面和防尘密封件的衬套端面抵接部之间，以保持密封状态。因此，防尘密封件能够稳定地保持在凸台部件的内周侧，防止了防尘盖的拉出。
