ABSTRACT:
A seal for use in the gear housing (52) of an elevator hoist drive mechanism (10) is provided. The first embodiment, seal (98), is generally formed of an annular body of elastomeric material having an outer sealing section (102) with first sealing surface (104) for engagement with the inner rim (86 and 88) of gear housing (52), an inner sealing section (106) with second sealing surface (108) for engagement with cylindrical connecting drive shaft (69) and a bonding wall (100) for securing seal (98) on gear housing (52). Sections (102 and 106) are separated by a V-shape groove (124) to insure independent resilience of the sections. Seal (98) is split to form ends (112 and 114) to simplify installation.
The second embodiment, seal (132), is generally formed of an annular body of elastomeric material having a fabric coating. Seal (132) has a compression surface (140) deformably securing the seal to gear housing (52), and a shaft sealing surface (142) with shaft sealing lip (144) for sealing engagement with cylindrical connecting drive shaft (69). A U-shape notch is provided between internal wall (148) and shaft sealing surface end wall (146) for enhanced flexure of shaft sealing lip (144). Seal (132) is split to form two ends to simplify installation of the seal.
