Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
Example 1:
referring to fig. 1, the utility model provides a speed reducer double-lubrication mechanism of a coal mill powder concentrator. The mechanism comprises a sealing ring sleeved on an input shaft of the speed reducer, an upper bearing gland is arranged on the periphery of the sealing ring, and a cavity for mounting an upper bearing is formed between the upper bearing gland and the upper bearing pedestal as well as between the upper bearing gland and a connecting piece. And a glycerol oil nozzle is arranged above the upper bearing and used for injecting glycerol to lubricate the upper bearing. Set up the skeleton oil blanket between upper bearing support and the connecting piece, can block the thin oil of below to splash to the upper portion bearing in on the one hand, on the other hand can seal the upper portion bearing that adopts glycerine lubrication, prevents that glycerine from flowing out. The lower bearing is arranged at the lower part of the input shaft of the speed reducer and is lubricated by thin oil, the lower bearing and a gear in the speed reducer can be lubricated by thin oil together, the lower bearing keeps the original structural design, and the reconstruction cost can be saved.
Specifically, the upper bearing support is annular, an inner ring of the upper bearing support is connected with the input shaft of the speed reducer, an outer ring of the upper bearing support is connected with the framework oil seal, and the framework oil seal is sleeved outside the upper bearing support.
Specifically, the lower end of the upper bearing pressure cover abuts against the outer ring of the upper bearing, and the upper bearing pressure cover is connected with the connecting piece through a bolt. The inner side of the lower part of the connecting piece is provided with a circle of gap for installing a framework oil seal. The upper part of the connecting piece is connected with the speed reducer shell through a bolt. The connecting piece is of an annular structure, the middle part of the inner side of the connecting piece is connected with the outer ring of the upper bearing, the upper part of the inner side of the connecting piece is abutted against the upper bearing gland, and the lower part of the inner side of the connecting piece is connected with the framework oil seal; the outer side of the speed reducer is connected with a speed reducer shell.
The utility model adds the framework oil seal at the lower part of the upper bearing of the input shaft of the existing coal mill powder concentrator, changes the original thin oil splash lubrication into the glycerol lubrication, can greatly prolong the service life of the upper bearing of the input shaft of the coal mill powder concentrator and reduce the production cost.
Although embodiments of the present invention have been shown and described above, it should be understood that the above embodiments are illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiments without departing from the scope of the present invention.
