A locking assembly for a bearing, such as a bearing for a rolling mill roll, the roll having a journal for the bearing, the bearing including a cylindrical sleeve member at its outermost end mounted on an axially outer portion of the journal, the end of the sleeve formed to have a radially inward shoulder, and a radially outwardly cylindrical projection, the shoulder having a wedge-shaped cam surface formed at its outer most axial surface, an axially movable outer nut constructed to pass over the journal and having a radially inwardly annular shoulder, the shoulder of the nut having a wedge-shaped cam surface arranged to cooperate with the cam surface of the sleeve shoulder to force the sleeve in an axially inward direction on its rotation when secured to the roll, the nut including several radially outward holes spaced angularly of the axis of the bearing for allowing the nut to be rotated, cooperative openings in the nut and the projection of the sleeve for receiving bolts for securing the nut to the sleeve once the two cam surfaces have been brought into a desired locking position, the nut having an axially outwardly annular shoulder, and the roll having a retainer member for engagement with the shoulder of the nut for securing the locking assembly in a fixed position relative to the roll and bearing.
A locking assembly for securing a bearing on a journal of a shaft, said assembly comprising a cylindrical sleeve member located at the one end of the bearing and in engagement therewith and mounted on an axial portion of the journal, the end of the sleeve opposite said engaging end having a first engagable surface, said first surface having a cam surface, a rotatable cylindrical nut mounted concentric with the journal adjacent said opposite end of said sleeve and having a second engagable surface, said second surface having a cam surface arranged to engage and cooperate with the cam surface of said first surface to force said sleeve in an axially inward direction on rotation of said nut when secured to the shaft, said nut including means for allowing said nut to be rotated, means for securing said nut to said sleeve once the two cam surfaces have been brought into a desired locking position, and a third engagable surface formed on said nut, means for engagement with the third surface for securing the locking assembly in a fixed position relative to the shaft and bearing.
A locking assembly for securing a bearing on a journal of a shaft, said assembly comprising, a cylindrical sleeve member located at the outermost axial end of the bearing and in engagement therewith and mounted on an axially outer portion of the journal relative to said bearing, the outer axial end of the sleeve having a first shoulder, including an annular first engagable surface, said sleeve having a radially outwardly cylindrical projection at said axial end, said first surface having a portion with a number of spaced apart wedge-shaped cam surfaces, at the outer most axial portion of said first shoulder, an axially movable cylindrical nut mounted concentric with the journal and having a second shoulder, including a second annular engagable surface, said second surface having a portion with a number of spaced apart wedge-shaped cam surfaces arranged to engaged and cooperate with the cam surfaces of said first shoulder to force said sleeve in an axially inward direction on rotation of said nut when confined to the roll, said nut including means for allowing said nut to be rotated, cooperative openings in said nut and said projection of said sleeve for receiving bolts for securing said nut to said sleeve once the cam surfaces of said sleeve and nut have been brought into a desired locking position, and a third engagable surface formed on said nut, means for engagement with the third surface for securing the locking assembly in a fixed position relative to the roll and bearing.
