Composite tension rod terminal systems

InactiveUS6886484B2Superior combination of strengthSuperior combination of lightnessConnecting rodsRod connectionsFiberMechanical engineering
A composite tension rod is received in the sleeve portion of a shank that forms part of a terminal fitting, and is spaced from the shank sleeve and connected thereto by a potting resin. The shank sleeve wall tapers out from thin at its distal end to thick at the bury depth of the rod. The rod is tapered outwardly from a point of minimum diameter at its inner end to its full diameter a given distance from the end. The shank sleeve and rod have complementary dual tapering along said length such that as the diameter of the rod along said distance increases, the wall thickness of the shank sleeve decreases. The resin layer and the rod are secured to each other against relative longitudinal movement, as are the resin layer and the shank sleeve.
In another aspect of the invention, a tension rod sleeve is fixed to the tension rod and extends over the distal end of the shank sleeve and along all or a majority of the length of the shank sleeve. The rod sleeve is tapered so that its wall thickness decreases to a minimum in the vicinity of the proximal end of the shank sleeve, or the rod sleeve, as it extends along the shank sleeve, is divided, or divides, into two halves or bands which join to form loop extending around a loop-engaging, convex, fiber-turnaround face formed on the terminal fitting. Such face extends transversely from one side to the other of the fitting.

Engine cracking connecting rod and machining method thereof

The invention discloses an engine cracking connecting rod and a machining method of the engine cracking connecting rod. The engine cracking connecting rod comprises a connecting rod body and a connecting rod cover, wherein the connecting rod body is connected with the connecting rod cover in a cracking position of a connecting rod big head through a connecting bolt, U-shaped grooves which are symmetrical relative to a cracking surface are formed in the cracking position of the connecting rod big head, V-shaped splitting grooves are formed in the inner edge, corresponding to the cracking position, of a big head hole of the connecting rod big head, and the V-shaped splitting grooves are symmetrical relative to the cracking surface. The machining method comprises the steps that a forged connecting rod blank with the two symmetrical U-shaped grooves is machined in a rough mode; the connecting rod is cracked into the connecting rod body and the connecting cover; the cracked connecting rod is machined in a fine mode, and a cracking connecting rod finished product is formed. The engine cracking connecting rod and the machining method of the engine cracking connecting rod can lower the cracking difficulty, guarantee the cracking effect, reduce production work procedures, improve reset accuracy after cracking, and guarantee the overall performance of the connecting rod.
