Abstract: A modular crankshaft features a connection system between modules that features opposed female receptacles. A pin having opposed beveled ends and hydraulic passages with it is inserted into the opposed receptacles. A pair of seals is disposed on the beveled ends and straddles a hydraulic fluid outlet. The crankshaft wall that defines each receptacle is designed to flex in response to applied hydraulic pressure between the seals on the tapered pin portion. A notch at the base of the receptacle in the crankshaft reduces stress concentration and enables the wall defining the crankshaft receptacle to come back when hydraulic pressure through the pin is removed. The opposed crankshaft receptacles are flanged to allow them to be pulled together over the pin. An interference fit results around the pin after the flanges are mated and the hydraulic pressure is removed.

Abstract: A vacuum food processor canister vacuum coupling assembly includes a canister closure defining a recess in a top portion of the closure. A valve stud within the recess defines an upper rim and a vacuum port extending through the closure. A vacuum valve plunger includes a valve stem extending through the vacuum port and defines a pliable upper peripheral flange to engage the rim of the valve stud to form a releasable seal. A vacuum coupler fitting is constructed to be manually press-fitted onto the valve stud to provide a press-fit seal therebetween to enable evacuation of air from a canister through the vacuum port. The press-fit seal can be maintained without manual support. The valve plunger can be displaced to release the vacuum. The valve plunger is positioned within the recess and the vacuum coupler fitting has sufficient clearance to avoid displacing the valve plunger during fitting removal.

The piston rod and the connector rod can be coupled and uncoupled without the use of heavy wrenches, hammers, or impact tools.

Abstract: A lubrication system is set forth for a universal joint. A cross of the universal joint has four trunnions extending therefrom along two mutually perpendicular lines. Bearing cups are rotatably received on the ends of the trunnions and the cups, in turn, are held by universal joint yokes. Lubrication passages extend from a central portion of the cross outwardly to cavities located at the ends of the trunnions. A passage extension extends substantially through each cavity from the lubrication passage toward the end of the trunnion. A lubricant retainer is of generally inverted U-shaped configuration and extends over the passage extension. The retainer has openings near the bottom of the cavity and is centered in the cavity by a flange on the passage extension or by an outer flange at the edge of the retainer. The retainer prevents air from being trapped in the bottom of the cavity so that the cavity will always be filled with lubricant.

Should a steering link and its associated joint loose the cup fitting, use of a grease cup and mounting of the joint therewithin is lost to effect rapid erosion of the joint, wherein the structure provides for an angulated plate member containing a replacement cup secured to the steering link at the joint to retain the joint and replacement cup to the steering link.

Abstract: A hydraulically expandable hub having a collection groove and a vent port to prevent the leakage of oil upon the shaft to which the hub is mounted and a method for using such a hub is disclosed. The oil collection groove is located along the inside diameter of the hub between each end of the hub and the oil groove also located on the inside diameter of the hub. A vent port is connected to the collection groove so a vacuum source can be coupled to the hub. The negative pressure produced by the vacuum source at the collection groove sweeps or pulls oil seepage from the oil groove into the collection groove which is transported to the hub exterior through the vent port. Such a hub can be altered in position about the shaft without leaving oil residue along the shaft.
