ABSTRACT:
The present invention includes a rear seal assembly that holds and seals a rotatable shaft extending through the cooling chamber and extending axially outboard through a rear wall in the cooling chamber. In the interior of the cooling chamber, the seal assembly includes a first resilient seal having a coupling section fitted about the shaft and a radially protruding lip section at the base of the coupling section. At the axially outboard end portion of the seal housing, an axially outboard male threaded extension protrudes from a wall abutment surface of the seal housing. The outboardly extending male threaded extension of the seal housing mates with complementary threads in the hole through the rear wall of the cooling chamber. A retaining ring, that is metal in the preferred embodiment, is threaded from the outside of the chamber onto the outwardly extending male threaded extension of the seal housing. The retaining ring has a threaded outer circumference. A bearing housing, that is metal in the preferred embodiment, is threadably mounted on the retaining ring. The bearing housing holds, in a partial bore, a ball bearing assembly that holds the shaft.
