Background technique
Existing boats and ships are mainly originated by engine or motor for driving, reducing rotating speed via speed reducer and improving torsion, after speed reducer slows down, force-output shaft by speed reducer outputs power, the deceleration principle of speed reducer, generally use pitch wheel group, or utilize the worm and gear group of engagement, to enter power by what run up, what slow down and operate for low speed height torsion exerting oneself, simultaneously for preventing the overheated or wearing and tearing of speed reducer inner member, a large amount of lubricant oil can be injected in speed reducer, to be reached for the cooling of speed reducer inner member and the effect such as lubrication.When speed reducer operates, its internal lubrication oil just can produce pressure change because of the spinning movement of the elements such as gear, the friction produced during the simultaneously element running such as gear, also the rising of oil temperature and the oxidation of oil plant can be caused, and one oil pressure pressure of outer is formed to reducer shell inside, this oil pressure of outer just can be carried lubricant oil secretly and spill through the group place of connecing such as inputting shaft and shaft-cup hole of speed reducer, causes lubrication effect to reduce, and makes the situations such as the wearing and tearing of speed reducer inner piece, damage.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides that a kind of structure is simple, the inputting shaft assembly of the reducer gear case peculiar to vessel of good sealing effect.
The utility model solves the technological scheme that its technical problem adopts: the inputting shaft assembly of this reducer gear case peculiar to vessel, mainly comprise casing, axle sleeve, inputting shaft and rotating component, the side of casing has inputting shaft hole, inputting shaft hole inwall is provided with retainer I, inputting shaft is provided with inputting shaft in hole, inputting shaft overcoat has axle sleeve, inputting shaft is positioned at the trepanning of axle sleeve, axle sleeve is positioned at the opening in inputting shaft hole and is butted on retainer I place, one end of axle sleeve is formed with flange, inputting shaft is provided with rotating component, and rotating component is between inputting shaft and axle sleeve.
The inwall of described axis hole is provided with groove I, and groove I is embedded with retainer, and inputting shaft is provided with groove II, and groove II is embedded with retainer, and axle sleeve is provided with retainer II relative to the other end of flange, and rotating component both sides are butted between retainer and retainer II mutually.
The outer wall of described axle sleeve is provided with caulking groove, is provided with the first Sealing in caulking groove.
Described inputting shaft is provided with retainer III, and on retainer III, cover has the second Sealing, and the outside of the second Sealing contacts with the retainer II on axle sleeve.
The effect that the utility model is useful is: the utility model structure is by the form of assembling combination, effectively improve the convenience that the assembling and dismantling of reducer gear case change the outfit, when the component wear such as inputting shaft will be changed, when not destroying Sealing, the elements such as inputting shaft can be changed, to reach the effect of saving element assembly cost, effect of the design double cutting off inflow oil seepage of the first Sealing and the second Sealing, to improve the benefit preventing oil seepage.
