摘要： In a travelling crawler belt in which a pair of left and right links are connected by pins respectively press-fitted into the corresponding links, a fixing end surface of the pin or the links is continuously and locally pressed and deformed in an axial direction of the pin from the fixing end surface, along an inner or outer peripheral portion of an opening of a pin-press-fit hole. Then, a part of the opening peripheral portion of the end of the pin or the link is enlarged or reduced in diameter, so that the diametrically increased or reduced portion is retained and fixed to a mating retaining space. With this fixing method, it is possible to easily and strongly couple the links and the pin, and to obtain a fixing structure of the links and the pin for a crawler belt capable of sufficiently securing a holding force of the pin in the axial direction. When the pin is fixed at the time of the assembling of the pin, an existing press can be used without requiring any exclusive machine, and it is possible to easily and reliably assemble the links and the pin for the crawler belt.
摘要翻译：在其中一对左右连杆通过分别压配合到相应连杆中的销连接的行驶履带中，销或连杆的固定端面在轴向方向上连续地局部地按压和变形销从固定端表面沿着针压配合孔的开口的内周或外周部分。然后，销或端子的端部的开口周边部分的一部分的直径被扩大或减小，使得直径增大或缩小的部分保持并固定到配合保持空间。通过这种固定方法，可以容易且牢固地连接链节和销，并且获得能够充分确保销在轴向方向上的保持力的履带和销的销的固定结构。当销的组装时销被固定时，可以使用现有的压力机，而不需要任何专用机器，并且可以容易且可靠地组装用于履带的连杆和销。

摘要： An link of a caterpillar which is allowed to maintain stabilized durability for a long period. The fixing structure has a link, and a pin inserted into a pin inserting bore formed in the link. A peripherally extending concave groove formed on the end portion of the pin and an opening periphery conjugate to forms an annular space. In order to limit relative escaping motion of the pin in the off-opening side (toward receding direction), a escape limiting ring is fitted into the annular space. The hardness of the bottom surface of the peripherally extending concave groove is lowered than the surface hardness of a link engaging portion of the pin.

摘要： A seal assembly has simple assembly structures, and provides secure sealing effects. A crawler-track connection structure allows the seal assembly to be easily mounted, and securely prevents overflow of a lubricant and the like to the outside. A pair of seal rings (1) and (1) individually having lip portions (23) and (23) are disposed such that each of the lip portions (23) and (23) protrudes in a direction opposing an axial direction, and a load seal ring (2) is compressed and inserted between the pair of seal rings (1) and (1). The load seal ring (2) exerts reaction forces on the pair of lip portions (23) and (23) outwardly in the axial direction.

摘要： A pressure receiving surface (8) having a diameter gradually decreasing in an axially inward direction is formed at an outer end portion of a pin (1), whereas a pressing portion (7) is formed at a circumferential edge of an opening of a pin insertion hole (5) of a link (2). A retaining ring (3) is formed with a friction surface (9) to be press-contacted to the pressure receiving surface (8) when a force is applied from the pressing portion (7) upon development of a relative movement in a disengaging direction. The retaining ring (3) and the pressure receiving surface (8) share a greater area of contact than in the prior art, providing sufficient friction. This makes possible to provide a fastening structure of the link and the pin of a crawler belt which can be assembled by simple operation at a low cost, without requiring a high machining accuracy, and thus can be manufactured at a low cost.

摘要： A roller wheel for a track-type travelling vehicle is disposed on a non-ground-engaging side of a track and supported by a vehicle body frame. The roller wheel includes a shaft, a roller assembly and a bearing. The shaft is supported by the vehicle body frame. The roller assembly is disposed on an outer periphery of the shaft. The bearing allows the roller assembly to be rotatably supported by the shaft therethrough. The roller assembly includes a tubular inner roller shell disposed closer to the vehicle body frame, and a tubular outer roller shell disposed outwards of the inner roller, the tubular outer roller shell being coupled to the inner roller shell by a straddle fitting structure.

摘要： To provide a bearing device, which can be easily processed, and whereby, its durability is capable of being improved and a load (tractional force) can be remarkably increased till the burn-in occurs and a pin for the bearing device. The bearing device is provided with a bush and a pin to be inserted in this bush. When an external force is acting in a certain direction, the bush and the pin are relatively rocked, and a slidable range H is formed, in which an outer peripheral face of the pin and an inner peripheral face of the bush partially and slidably contact with each other. An oil reservoir is provided at the side of the pin in order to prevent a no-lubrication portion, to which no lubrication oil is supplied, from being formed in the slidable range H.

摘要： A bearing device includes a bush and a pin inserted into the bush, whereby an outer peripheral face of the pin and an inner peripheral face of the bush contact each other. At least two oil reservoirs are formed on the outer peripheral face of the pin are and elongated along the length of the pin. The interval between the reservoirs is such that an angular range centered on the pin axial center between the first reservoir and the last reservoir is not more than a center angle of 40 degrees centered on the pin axial center. At least one of the reservoirs is configured by a plurality of punctate concave portions.
