A master link for a track chain assembly is provided. The master link includes a body portion having first and second spaced apart apertures extending therethough. A gap extends radially outward from one of the first and second apertures. At least one fastener operatively engages an aperture that extends through the gap. As the fastener is secured the width of the gap is reduced thereby reducing the diameter of one of the first and second apertures providing a clamping force.

Master link for a track chain

A method and apparatus of assembling a joint of an endless track chain (10) for track-type machines to prevent endplay in the joint (14) is disclosed. The joint (14) includes a pair of links (12) and a cylindrical pin (52). Each link (16) includes a outwardly offset outboard end collar (20) having a boss (50) extending outwardly therefrom and a bore (40) therethrough. Each boss (50) has an outer surface (44). The pin (58) includes opposite end portions (58). Each end portion (58) is pressed and non-rotatably mounted into respective one of the bores (44) of the outboard end collars (20). The method comprises the steps of forming an annular groove (62) about each of the end portions (58), placing a swage tool (67) against the outer side surface (44) of the boss (20) in axial alignment with the pin (52), and applying a sufficient force on the swage tool (67) to form at least one mechanically formed nodule (64) protruding from the outer side surface (38) into a respective ones of the grooves (62). The nodule (64) having a cross-sectional configuration substantially conforming to the groove (62).

Method and apparatus for retaining a track chain joint

A method for managing a drive mode of a tracked vehicle, including reading an output of a sensor and, in response to the output of the sensor, performing a control action to manage the drive mode of the vehicle. An apparatus for managing a drive mode of a tracked vehicle is also provided and comprises a sensor outputting a signal that conveys information that can be used to manage the drive mode.

A hydrocarbon converter furnace has an upper convection heating zone and a lower radiant heating zone, and tubing extends in those zones to convey a fluid hydrocarbon feed and steam in sequence through the convection and radiant heating zones. The tubing includes a feed section and branches therefrom in the radiant section of the furnace, the feed section and branches arranged so that the hydrocarbon and steam flow from the feed section to said branches; also provided is valving for controlling the relative rates of flow in the branches to reduce differential coking in the branches.

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.

Provided is a wave-power generator capable of adjusting a natural period (natural frequency) in response to a changing wave period. The wave-power generator (1) includes a weight (3) that is installed in a floating body (2) via a spring (4) and that linearly reciprocates in response to a fluctuation of a water surface (7) and a generator (8) that generates power by being driven based on the linear reciprocating motion of the weight (3). An additional-mass body (6) for adding a mass to the mass of the weight (3) is further included.

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.
