Abstract
A universal gland defining a central opening for mounting the gland coaxially about a machine shaft to the machine housing, the mounting done with a plurality of bolts at bolt hole positions in the housing. A gland body includes a mounting surface for placement adjacent the housing, and facing away from the mounting surface at least one tab-engaging surface is engaged by tabs for transferring forces from the bolts to the machine via the gland body. Bolt-mounting tabs are configured to extend radially beyond the periphery of the gland body a distance at least to the bolt hole positions of the machine. The tabs are angularly adjustable about the gland body.
Claims34
A universal gland body defining a central opening, said gland body for mounting, coaxially about a machine shaft, to a machine housing through which said shaft extends, the mounting done with a plurality of bolts at fixed bolt positions in said housing, said gland body characterized in that
- said gland body is adapted to be mounted to said machine housing via mounting tabs and comprises a mounting surface for placement adjacent said housing, at least one tab-engaging means having a tab-engaging surface facing away from said mounting surface, means for application of pressure from a location extending radially beyond the periphery of said gland body to secure said gland body to said housing via a plurality of said mounting tabs engaged with said tab-engaging surface, said application mans configured to engage said tabs at circumferentially adjustable positions relative to said gland body with said tabs extending radially beyond the periphery of said gland body for application of pressure from said bolts to secure said gland body to said housing via said tabs.
A universal gland having a central opening thereof for mounting said gland coaxially about a machine shaft, said gland for mounting to a machine housing through which said shaft extends, said mounting done by a plurality of bolts at fixed bolt positions on said housing, said gland comprising
- a plurality of bolt-mounting tabs for cooperation with said bolts, and said gland further comprising a gland body having mounting means for mounting said tabs in an orientation such that said tabs extend radially beyond the periphery of said gland body, said mounting means comprising a universal receiver for receiving said tabs at circumferentially adjustable positions relative to said gland body, said tabs having projections for detachably connecting said tabs to said gland body via said mounting means, and said mounting means comprising at least one tab-engaging surface for engagement by said tab projections for transferring mounting forces from said bolts to said machine housing via said gland body.
A bolt-bearing tab for mounting a gland body to a machine housing mounting surface by transferring mounting force generated at a mounting bolt connected to said housing to said housing mounting surface via said tab and said gland body, characterized in that
- said tab comprises a body and a projection extending away from said body, said body having a top surface and a bottom surface with a bolt mounting hole extending therebetween, said hole extending along a bolt mounting axis for receipt of a mounting bolt, said bottom surface defining a gland-body-engagement surface, said projection extending transversely to said axis and having a tapered surface extending axially generally along said axis between said top and bottom surfaces, said tapered surface widening axially as said projection extends away from said body.
