摘要： Past pin joint assemblies attaching a lift arm to a construction machine have utilized grease lubricated pins. Deflection of the pins during operation caused damage to both the pin and surrounding structure. Additionally, the use of grease requires daily lubrication schedules. The present invention overcomes these and other problems by providing an oil sealed pin joint assembly which virtual eliminates daily lubrication needs. A pin is utilized with a variable profile including first and second end portions which diverge inwardly from a first predetermined diameter and terminate at a second predetermined diameter. The second diameter is in substantial axial alignment with a contact surface of a first and second collar with first and second bearing assemblies, respectively. The pin diverges outwardly from the second diameter and terminates at a third predetermined diameter. A plurality of radii blendingly interconnect the first, second and third diameters. During operation, the pin deflects and the relative location and size of the diameters and radii promotes a uniform distribution of forces across the pin and into the surrounding structure. Uniform distribution of pin forces cause less damage to the pin and surrounding structure.

摘要： A strain sensing device is provided, which may include a hollow, cylindrical member having an inner surface and an outer surface. The outer surface may have an outer diameter corresponding approximately in size to an inner diameter of an inner surface of a cylindrical bore of a structural component configured to undergo mechanical loading. The hollow, cylindrical member may be configured to mate to the inner surface of the cylindrical bore of the structural component such that strain in the structural component is translated into strain in the hollow, cylindrical member. The strain sensing device may also include one or more strain sensing elements attached to the inner surface of the hollow, cylindrical member and configured to detect strain exhibited by the hollow, cylindrical member.

摘要： The design and construction of present oil pan assemblies have caused increased manufacturing cost, reduced seal life and reduced engine reliability. The present invention overcomes these oil pan assembly construction problems by using an oil pan assembly including a thin walled structure having a drain port formed therein. The thin walled structure further has a frusto-conical contoured lip around the drain port being concave toward the inside surface. The frusto-conical contoured lip has a sealing surface on the portion of the outside surface forming the frusto-conical contoured lip. A reinforcing member having a threaded hole therein and a conically contoured support surface at one end of the threaded hole is positioned so that the threaded hole is generally centered about the drain port. The support surface is located in supporting relationship to the frusto-conical lip. A drain plug having a threaded end and a sealing surface also includes an O-ring seal removably attached to the drain plug. Thus, when the components are in functionally working relationship, the O-ring engages with the sealing surface of the drain plug and the sealing surface of the frusto-conical contoured lip.
