Abstract
The invention discloses a fast oil releasing structure for a hydraulic clutch. The hydraulic clutch is composed of a clutch base arranged on a transmission shaft in a sleeving mode, a clutch shell, an inner and outer friction plate, a piston and a spring, and the inner and outer friction plate, the piston and the spring are arranged between the clutch base and the shell. The clutch base and a transmission gear arranged on one side and movably arranged on the transmission shaft in a sleeving mode are integrally manufactured, and the clutch shell and an input gear arranged on the transmission shaft in a sleeving mode in a shrinkage fit mode are integrally manufactured. An oil releasing hole communicated with a hydraulic oil cylinder is transversely formed in the side wall of the clutch shell, and an oil releasing valve capable of fast releasing oil in the hydraulic oil cylinder is arranged at the inner end of the oil releasing hole and is close to the piston. The oil releasing valve is a one-way valve and comprises a valve seat arranged at the inner end of the oil releasing hole, and a notch circular groove is formed in the middle of the valve seat. A through hole transversely communicated with the oil releasing hole is formed in the bottom face of the notch circular groove. A steel ball capable of moving in the notch circular groove and closing the through hole is placed in the notch circular groove. The fast oil releasing structure has the advantages of being simple in structure, convenient to use and operate and the like.
Description
Technical field
What the present invention relates to is a kind of quick oil drainage structure for hydraulic coupling, belongs to marine gearbox technical field.
Background technique
in marine gearbox, often application hydraulic coupling is as transmission part, wherein when hydrovalve disconnects, though the oil circuit in hydraulic coupling cuts off, but the hydraulic oil in oil circuit does not arrange light completely, therefore easily cause band row in clutch, affect its using effect.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, use easy to operate, hydraulic coupling band row problem can be solved preferably, improve the quick oil drainage structure for hydraulic coupling of hydraulic coupling using effect.
The object of the invention is to have come by following technical solution, a kind of quick oil drainage structure for hydraulic coupling, described hydraulic coupling by the clutch base be nested with on the rotating shaft, clutch housing and between clutch base and shell in outside friction disc, piston and spring form, described clutch base with while put, the driving gear of kink on transmission shaft be made into integration, and clutch housing and the input gear of another hot jacket on transmission shaft are made into integration; The sidewall of described clutch housing is horizontally arranged with and is communicated with the oil leak hole of hydraulic jack, and in the inner of oil leak hole, next-door neighbour's piston is provided with the oil drain valve oil in hydraulic jack can discharged fast.
Described oil drain valve is an one-way valve, it comprise one be arranged on oil leak hole the inner, centre is provided with the valve seat of notch circular groove, described notch circular groove bottom surface offers the through hole of cross connection oil leak hole, and is placed with in described notch circular groove and can moves the steel ball that also can close through hole at notch circular groove.
It is simple that the present invention has structure, uses easy to operate, can solve hydraulic coupling band row problem preferably, improve the features such as hydraulic coupling using effect.
