Description
Technical field
Of the invention and a kind of sanitation-grade stirs dedicated deceleration transmission mechanism.
Background technology
General speed reduction gearing generally use outside framework oil seal is sealed, the lubricating oil being placed in speed reduction gearing
It is sealed against leak-stopping oil.However, in the speed reduction gearing course of work, the long-time friction between outside framework oil seal and axle
The abrasion generation or outside framework oil seal for easily causing outside framework oil seal work long hours and cause aging, oil leak can be all produced, so as to shadow
Ring the life-span of speed reduction gearing or cause the pollution of product.
To solve the problem, Chinese patent：The patent No.：200720151973.0 denomination of invention：A kind of leakproof of reductor
Oily device, a kind of structure that the lubricating oil in reduction box is isolated with output shaft using dry-well set and realizes drip-preventing function is disclosed,
The dry-well nested structure of the disclosure of the invention by dry-well cover sealing fixed seat be fixed in frame, driven gear by hollow shaft with it is defeated
Go out axis connection, output shaft upper end is connected with hollow shaft upper end.There is following deficiency in the structure of invention：1st, dry-well set is with frame
Split type structure, dry-well set need that dry-well set is fixed in frame by structures such as seal and bolts, assembling process it is complicated and
For a long time oil leak is caused using the easy aging of seal；2nd, hollow shaft and the connection of output shaft upper end carry out transmission campaign, therefore need
Output shaft length that will be longer is used to connect, and dry-well is placed between hollow shaft and output shaft, and the structure causes to export shaft length
Lengthen, so as to cause speed reduction gearing overall structure to become big；3rd, because output shaft length is long, for output shaft rotation process
Middle vibration is, it is necessary to which multigroup bearing is used to support output shaft, so as to further cause the complicated of speed reduction gearing；4th, lead to
Cross hollow shaft and transmit moment of torsion, when transmission moment of torsion is excessive, easily distortion causes to damage hollow shaft；5th, hollow shaft and dry-well set, dry
Well covers has less gap between output shaft, during output shaft rotation, hollow shaft and dry-well set, dry-well set and output
The lubricating oil that gap between axle easily produces pressure differential and causes to be placed in cabinet is inhaled into gap and causes oil leak.
The content of the invention
The present invention stirs dedicated deceleration transmission mechanism to a kind of sanitation-grade that proposes of problem above, and the device uses dry-well
