| Abstract:
This invention relates to machine drives and particularly to a driving connection between two shafts or spindles, which rotate at a fairly high speed.
It is an object of my invention to provide a. driving means between such shafts which will not become overheated in operation and in which means is provided for cooling the power transmitting means between the shafts or spindles.
It is a further object of the invention to provide means whereby the driving connection may run in a bath of oil with means for cooling this oil to thus keep the driving connection from becoming overheated.
Claims:
1. In a machine drive, two substantially parallel spaced shafts, sprockets secured to said-shafts, a chain drive about said sprockets whereby one shaft may be driven by the other, means for rotating the driving shaft, a casing about the sprockets and chain and adapted to hold an oil-bath for a portion the chain, and means within the casing for circulating a cooling fluid through said casing.
2. In a machine drive, two shafts, a driving connection between said shaft, a casing about, said driving means adapted to hold a bath of oil for a portion of the driving means to run in, and means within the casing, for circulating a cooling fluid through said casing.
3. In a machine drive, two substantially parallel, shafts, sprockets secured to said shafts, a driving chain connecting said sprockets, means for rotating one of said shafts, a casing enclosing the chain and sprockets and adapted to hold a bath of oil for a portion of the chain, and means within the casing for circulating air through the casing to cool the oil and chain.
4. In a machine drive, two shafts, a driving connection between said shafts, a casing enclosing said driving connection and provided with an air inlet opening and an outlet opening, a fan adjacent the inlet opening, driven by one of said shafts and arranged to draw air into the casing through said opening and a bath of oil in said casing about a portion of said driving connection.
5. In a machine drive, two substantially parallel shafts, a driving connection between said shafts comprising sprockets secured to the shafts and a driving chain running on said sprockets, a casing enclosing said driving connection and provided with an air inlet opening and an air outlet opening, a fan adjacent said inlet opening driven by one of said shafts and arranged to circulate air through the casing from said inlet opening to the outlet opening, and an oil bath in said casing enclosing a portion of said chain.
6. In a machine drive, two substantially parallel shafts, a driving connection between said shafts comprising sprockets secured to the shafts and a driving chain running on said sprockets, a casing enclosing said driving connection and provided With an air inlet opening and an air outlet opening, said casing being adapted to hold an oil bath for a portion of the chain, means for circulating air through the casing from the inlet to the outlet opening, and means arranged to direct oil from the interior walls of the casing to the inside of the chain.
7. In a machine drive, two substantially parallel shafts, a driving connection between said shafts comprising sprockets secured to the shafts and a driving chain running on said sprocket-s, a casing enclosing said driving connection and provided with an air in let opening and an air outlet opening, said casing being adapted to hold an oil bath for a portion of the chain, a fan adjacent the inlet opening driven by one of said shafts and arranged to circulate air through the casing from said inlet opening to the outlet opening, and a trough arranged to collect oil running down the inner surface of one of walls of the casing and direct it to the top or inner side of the lower run of the chain.
8. In a machine drive, a pair of shafts, a pair of sprockets carried by said shafts, a driving chain on said sprockets, a casing enclosing the sprockets and chain and containing a bath of oil for a portion of the chain to run in, said casing being provided with an air inlet and outlet openings, a fan driven by one of the said shafts for circulating coo-ling air through said casing from the inlet to the outlet, and heat radiating fins on the exterior of the casing.
9. In a machine drive, a pair of shafts, a pair of sprockets carried by said shafts, a driving chain on said sprockets, a casing enclosing the sprockets and chain and containing a bath of oil for a portion of the chain to run in, said casing being provided With air inlet and outlet openings, a fan driven by one of the said shafts for circulating cooling air through said casing from the inlet to the outlet, heat radiating fins on the exterior of the casing, and a trough arranged to collect oil running down the inner surface of the casing and direct it to the top or inner side of the lower run of the chain.
