摘要： A wear member (12) comprising a front end (51), a socket (53) having an open rear end to receive a nose (18) fixed to an excavating machine, the socket being defined by converging surfaces (55,57), side surfaces (59,61), a front surface (63) and the open rear end, and having a longitudinal axis (X), and a lateral surface (69) positioned between the front surface and the open rear end of the socket that faces in a direction generally toward one of the converging surfaces, whereby the lateral surface being inclined to the longitudinal axis to produce in use a resisting force (B1) having a component that tends to pull the wear member rearward onto the nose for certain loads (P1) applied to the front end of the wear member. Also disclosed is a wear assembly comprising such a wear member, a nose (18) and a lock (16).

摘要： A wear assembly (10) for attaching wear members to a lip of an excavator includes a wear member, a boss (28) and a lock (60). The lip includes an inner face, an outer face, a digging edge and a series of through-holes spaced rearward of the digging edge. The bosses (28) are each fixed to a face of the lip at a position rearward of the through-holes. The wear members each include slots to receive the boss (28) adjacent their rear ends, and openings for receiving the locks (60) at a position forward of the bosses (28). The openings are aligned with the through-holes in the lip. The lock (60) includes a wedge (62) and spool arrangement (64).

摘要： A bucket tool comprising an edge 7 secured to the lower part of a bucket in a lateral direction, tooth-mounting fittings 8 secured to the edge 7 with an interval between the fittings in the lateral direction, excavation teeth 9 attachably/detachably mounted on the tooth-mounting fittings 8 and protruding forward beyond the edge 7, a ground-leveling plate 10 having a lateral width equal to the lateral width of the lower part of the bucket, and coupling fittings 11 secured to the upper surface of the ground-leveling plate 10 with an interval nearly equal to the interval between the tooth-mounting fittings 8 and capable of being detachably attached to the ends of the excavation teeth 9. Upon attaching or detaching the coupling fittings 11 secured to the upper surface of the ground-leveling plate 10 to, or from, the ends of the excavation teeth 9, the ground-leveling plate 10 can be easily attached to, or detached from, excavation teeth of a bucket for excavation.

摘要： Tooth assemblies having a tip with ears extending rearwardly therefrom to mate with corresponding slots in an adapter are normally utilized in order to aid in the transfer of forces from the tip to the adapter. In the subject arrangement, a tip (12) includes a pair of opposed ears (32, 34) each having a pair of opposed edge surfaces (40, 42) that are angled one relative to the other. The pair of opposed ears (32, 34) of the tip (12) mates with a pair of corresponding opposed slots (54, 56) defined by the adapter (14). The pair of opposed slots (54, 56) in the adapter (14) likewise has a pair of opposed edge surfaces (60, 62) angled with respect to one another and are in confronting mating relationships with the pair of opposed edge surfaces (40, 42) of the pair of opposed ears (32, 34). This inhibits any outward movement of the pair of opposed ears (32, 34) with respect to the adapter (14).

摘要： Der Baggerzahn weist einen Zahnhalter (1) auf, an dessen einem Ende eine keilförmige Zahnnase (3) angeformt ist. Die Zahnnase (3) ist Träger einer keilförmigen Zahnkappe (5), in der ein keilförmiger Hohlraum (24) ausgespart ist. Bei montierter Zahnkappe (5) ist der Hohlraum (24) auf die Zahnnase (3) aufgeschoben, die damit die Zahnkappe 5 abstützt. Für eine gute Lagerung weisen die Keilflächen (8,9) der Zahnnase (3) senkrecht zur Längsachse (16) konvex gewölbte, von der Zahnkante (7) zur Nasenwurzel (17) kontinuierlich abnehmende Krümmungsradien auf. Dementsprechend weisen die Keilflächen (25,26) des Hohlraumes (24) konkav gewölbte, von dem Grund (28) zur Mündung (29) des Hohlraumes (24) dieselben kontinuierlich abnehmenden Krümmungsradien auf. Dadurch wird eine grossflächige Auflage der Zahnkappe (5) auf der Zahnnase (3) erreicht. Zur Sicherung der Zahnklappe (5) dient ein Sicherungsstift, der die Bohrungen (20,34) in der Zahnnase (3) und in den Seitenflächen der Zahnkappe (5) durchquert und dieselbe festhält.

摘要翻译： 挖牙具有一个齿架（1），其一端形成有一个楔形齿头（3）。 牙齿（3）是楔形齿盖（5）的支撑件，楔形中空空间（24）凹入其中。 当安装齿盖（5）时，中空空间（24）被推到齿顶（3）上，从而支撑齿盖（5）。 为了良好的轴承布置，齿牙（3）的楔形表面（8,9）具有垂直于纵向轴线（16）凸出拱形的半径，并且从齿缘（7）到鼻根部 17）。 因此，中空空间（24）的楔形表面（25,26）具有从中空空间（24）的底部（28）到口（29）连续减小的具有相同大小的凹形拱形曲率半径。 因此，齿盖（5）在大面积上承载在牙齿（3）上。 锁定销用于固定齿盖（5）。 锁定销穿过牙齿（3）中的孔（20,34）和齿盖（5）的侧面并将其保持在适当的位置。

摘要： A system for connecting a tool to an implement may have a clamp with a first side, and a second side with teeth. The system may also have a wedge with a body configured to engage the second side of the clamp, a channel formed in the body, and a collar. The wedge may additionally have an elongated pocket formed in the body, a first ramp extending between the channel and an end of the elongated pocket, and a second ramp located at a point between a base end of the body and the first ramp. The first and second ramps may be inclined relative to an axis of the channel. The system may further have a slider with a toothed surface configured to engage the teeth of the clamp when the slider is in the channel, and a fastener threadingly engaged with the slider.

摘要： A retention system is provided for use with a ground engaging tool. The tool retention system may have a generally C-shaped clamp configured to be disposed within an aperture of a work implement and to engage apertures in a tool adapter. The retention system may also have a wedge configured to be disposed within the apertures of the tool adapter and the work implement and against the generally C-shaped clamp. The retention system may additionally have a generally C-shaped slider configured to be disposed within the apertures of the tool adapter and to engage the aperture of the work implement. The C-shaped slider may have an opening oriented away from the generally C-shaped clamp, and the retention system may further have a fastener configured to connect the generally C-shaped slider to the wedge.
