ABSTRACT:
A gear drive casing apparatus is disclosed for enclosing a gear drive used in a hygienic and sanitary environment. The gear drive casing apparatus includes a member having an external contoured surface, the member enclosing the gear drive. A further member has a further external contoured surface, the surface and the further surface cooperating with each other to define therebetween a smooth uninterrupted intersection such that the contoured surfaces and the intersection therebetween are easily cleaned. The surfaces and intersection present a self-draining configuration which inhibits the entrapment therein of any deleterious materials that would support the growth of bacteria, fungi, mold and other microorganisms.
