  • Patent number: 4019824
    Abstract: A positive retaining ring system for axially securing a work element to a shaft which consists of a shaft provided with an annular recess having a trapezoidal cross-sectional configuration and which extends partially below a work element positioned on the shaft against a work element retaining shouler provided thereon. A segmented annular retaining ring having substantially the same trapezoidal cross-sectional configuration mounted in the recess with the vertical side thereof abutting the side of the work element. Clamping means circumferentially mounted on the segmented ring so as to exert an axial force thereagainst to wedge the ring into the annular recess. The resultant wedging force is translated into an axial force against the side of the work element so as to positively lock the work element against the work element retaining shoulder provided on the shaft.

  • Patent number: 4012154
    Abstract: A shaft bearing retention means comprises a segmented ring having a conical inner surface which is placed about a large diameter shaft having a corresponding conical indentation about its periphery to receive the ring. The segments are retained in assembled position on the shaft by joining pins extended through interengaging lapped tongues on the ends of each segment and by attaching one or more flanged retaining rings thereto by screws or bolts. Additional clamping screws or bolts pass through the retaining ring and are threaded into the segments, projecting beyond the latter so as to bear against a thrust ring through which the shaft passes. The axially adjustable thrust ring engages a bearing assembly which is fixed against axial movement by a shoulder on the shaft. Axial force is produced against the bearing assembly by the clamping bolts due to wedging action of the mating conical surfaces on the shaft and the segmented ring.

  • Patent number: 4004499
    Abstract: A bolt-on piston assembly wherein two piston pieces are clamped onto the rod which has an integral radial projection thereon for axially restricting the piston pieces disposed on axially opposite sides of the projection. A plurality of bolts extend into the pieces for releasably clamping the pieces relative to the radial projecting portion of the rod.

  • Patent number: 3978914
    Abstract: A heat exchanger and mounting structure therefor for use in connection with incinerators, for example, the heat exchanger formed of a ceramic wheel with a central core and an annular portion with gas passages extending axially therethrough. The ceramic wheel is mounted at the central core with a mounting means which comprises first and second wedge members in abutting relationship with opposite sides of the core. Means bias the wedge members towards each other so that the core is resiliently held under compression between the two wedge members to eliminate tension stresses on the ceramic wheel due to thermal expansion differences between the ceramic wheel and the mounting structure therefor. The mounting structure includes a first shaft secured to the first wedge member and a second shaft, tubular in shape and concentrically mounted on the first shaft, the second shaft being secured to the second wedge member. The shafts are supported on the cool side of the heat exchanger wheel by a pair of bearings.

  • Patent number: 3951048
    Abstract: A piston and rod assembly wherein the rod has a pair of axially spaced grooves and the piston includes recesses disposed in opposite faces. One of the grooves is radially larger than the other and locking members are disposed in the grooves of the rod and extend into the recesses. A retaining means including a snap ring and an annular ring which is L-shaped in cross section are disposed radially outwardly of the locking members in the first recess for removably retaining the locking members in the first recess. A pair of threaded screws may also threadedly interconnect the retaining ring and the piston.
