Abstract
An anti-loose and leakage-proof coupler casing comprises an input shaft, an output shaft and an end cover. A groove is formed in the lower portion of the input shaft, an O-shaped ring is arranged in the groove, the outer matching surface of the O-shaped ring is coated with a retaining adhesive, and a flange on the input shaft is connected with the casing through bolts, the interior of the casing is provided with hollows, and the casing is connected with a pump impeller through bolts; the output shaft is connected with a turbine through bolts and a retaining washer, and the turbine and the pump impeller are symmetrically arranged; and a bearing is arranged between the output shaft and the pump impeller, and a stop ring is arranged under the bearing; and an oil seal is arranged between the output shaft and the end cover, the end cover is fixed on the pump impeller through bolts, and a pump impeller and end cover joint surface is in a polygonal structure. According to the anti-loose and leakage-proof coupler casing, the density is high, casting flaws are few, and the yield is high; and the problem of leakage of working liquid media and cutting-off of the bolts, which are might be caused by frequent right and reverse starting of a tower crane, is solved, and the leakage-proof reliability of the casing is improved.
Description
Technical field
The utility model relates to the dydraudynamic drive unit field, is specially a kind of locking leakproof coupler shell.
Background technique
Tower crane adopts YOXJ type limit square fluid coupling at present, and inside is liquid-working-medium, and housing is aluminum alloy material, adopts sand casting process, low-pressure die casting, easily produces casting defects such as sand holes, pore.Input shaft and shell be connected with flange arrangement and two kinds of forms of steel aluminium alloying.
The seepage of liquid-working-medium is mainly that casting defects such as pore, sand holes cause in the fluid coupling.Casting defect adopts traditional impregnation technology and argon arc welding connection technology, and it is low that it produces efficient, and reliability is not enough.Sealing between input shaft and the shell is unreliable also can to cause seepage.Usually flange input shaft structure adopts sealing gasket and sealer and by bolton, but the easy loosening fluid seepage that causes in frequent clockwise and anticlockwise starting of bolt.Adopt the alloying of steel aluminium, be about to input shaft and be cast in shell, but the contour projector of aluminum alloy and steel is inconsistent, in the fluid coupling long-term work, produce under the state of higher temperature, easily make between the steel aluminium and produce the gap, cause the seepage of liquid-working-medium.
The model utility content
The technical problem that the utility model solves is to provide a kind of locking leakproof coupler shell, to solve the problem that proposes in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of locking leakproof coupler shell, comprise input shaft, output shaft and end cap, described input shaft bottom is provided with groove, be provided with O type circle in the groove, O type circle fit on surface scribbles retaining rubber, flange on the input shaft links to each other with shell by bolt, and enclosure is provided with hollow out, and described shell links to each other with pump impeller by bolt; Described output shaft links to each other turbine and pump impeller symmetric arrangement by bolt and retaining pad with turbine; Be provided with bearing between described output shaft and the pump impeller, the bearing below is provided with ring washer; Be provided with oil sealing between output shaft and the described end cap, described end cap is by being bolted on the pump impeller, and pump impeller and end cap junction plane adopt the plum blossom valve structure.
Preferably, all scribble the locking agent on the screw thread of above-mentioned bolt.
Preferably, described shell, pump impeller, turbine adopt the squeeze casting shaping material to make, the consistency height, and casting defect is few, the yield rate height.
The utility model is by squeeze casting compactness height, improved the reliability that housing does not produce seepage.Employing input shaft deep arranges O type circle and is coated with retaining rubber, and the loosening seepage that causes liquid-working-medium in the fluid coupling of bolt when preventing the input shaft clockwise and anticlockwise satisfies the non-leakage technical requirements of fluid coupling long-term work operation.
Beneficial effect:
The utility model consistency height, casting defect is few, the yield rate height; Liquid-working-medium seepage and the bolt that may cause when having solved frequent positive and negative startup of tower crane cut off phenomenon, improved the reliability that housing does not produce seepage.
