Description
Technical field
The utility model relates to the transmission device of a kind of, clutch suitable, deceleration, fine motion control function, be applicable to boats and ships transferring power usefulness, be particularly useful for speedboat and inland river, coastal various boats and ships by having of hydraulic control; The transmission device that belongs to the ship power propulsion system.
Background technique
In the prior art, light high-speed marine gearbox of the same type mainly is made up of box part, input block, transmission part, output block and control block hydraulic unit with, and it has identical along reduction speed ratio, forms power train by three five gears.Usually housing structure is the one package assembly, and volume is big, complex structure, and maintenance and maintenance are inconvenient, and stability of transmission and Security are not enough.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple and reasonable for structure, and volume is little, and maintenance and maintenance are convenient, the stable and reliable light high-speed marine gearbox of transmission performance.It mainly is made up of box part, input block, transmission part, output block and control block hydraulic unit with, wherein the structure of input block and transmission part is identical, include the driving gear of hot jacket on axle, friction pair, sky are enclosed within the driving gear on the axle, are used to separate return spring, the piston of friction plate; The piston of described input block and transmission part is placed in the piston cavity, and links to each other with hydraulic-pressure pump by the pressure oil passage; Subdivision structure before and after described casing is divided into, preceding casing be connected case as one.
The reversing control valve that is provided with control hydraulic fluid pressure and the flow direction in the described control block hydraulic unit with, this reversing control valve separately or with a fine motion control valve stack mounting on end cap.
Characteristics such as the utility model compared with prior art has simple and reasonable for structurely, and volume is little, and maintenance and maintenance are convenient, and transmission performance is stable and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of transmission part.
Embodiment
Below will the utility model is further introduced by accompanying drawing: shown in the accompanying drawing, the utility model mainly is made up of box part, input block 1, transmission part 2, output block 3 and control block hydraulic unit with 11, wherein the structure of input block and transmission part is identical, include the driving gear 4,5 of hot jacket on axle, friction pair 6, sky are enclosed within the driving gear 7,8 on the axle, are used to separate return spring 9, the piston 10 of friction plate; The piston 10 of described input block 1 and transmission part 2 is placed in the piston cavity, and links to each other with hydraulic-pressure pump by the pressure oil passage; Subdivision structure before and after described casing is divided into, preceding casing be connected case as one.
Described input block 1, transmission part 2, output block 3 are supported on the casing respectively by the conical bearing of face-to-face installation.The piston of described input block 1 and transmission part 2 is moved to the left, thereby makes the clutch friction chip bonding, otherwise under the effect of return spring 9, throw off friction plate under the working pressure oil effect from control block hydraulic unit with 11.
When being in the ahead running working position, pressure oil enters the piston cavity of input block 1, promote the piston pressing friction sheet that moves to left, driving gear 7 and driving gear 4 interlocks, the piston cavity of transmission part 2 did not have pressure oil and entered this moment, friction plate is in separated state, and the transfer route of power is shaft coupling 12 → input shaft 13 → gear 4 → gear 7 → gear 14 → output shaft 16.
When being in the reversing working position, pressure oil enters the piston cavity of transmission part 2, promote the piston pressing friction sheet that moves to left, driving gear 8 and driving gear 5 interlocks, the piston cavity of input block 1 did not have pressure oil and entered this moment, friction plate is in separated state, and the transfer route of power is shaft coupling 12 → input shaft 13 → gear 4 → gear 5 → gear 8 → gear 14 → output shaft 16.
When control valve parts 11 were in parking spot, the clutch of parts 1 and parts 2 all was in separated state, gear 7,8 unpowered inputs, the then unpowered output of output shaft.
Reversing control valve 15 can be separately or with 17 stack mountings of fine motion control valve on end cap.
When fine motion control valve 17 was in opening state, just the pressure and the flow direction that enters clutch fluid with reversing control valve 11 controls made operative clutch be in the sliding state (transmitting less moment of torsion and rotating speed) that rubs, and realizes that the dead slow speed of boats and ships propeller is rotated.
Reversing control valve described in the utility model is under idling or the low speed state at motor, can provide the pressure oil that is lower than normal working to clutch, make clutch be in the sliding wear state, transmitting torque reduces, thereby eliminates the gear-box gear Strike note that is caused by the engine speed instability.
Housing structure described in the utility model is the front and back subdivision, preceding casing with connect case as one, make volume littler, simple in structure.Subdivision structure simultaneously can be implemented in gear-box and does not pull down under the situation of common base and keep in repair, and has increased the convenience of maintenance.
The utlity model has the fine motion function, promptly when motor is in the slow-speed of revolution, pressure oil oil pressure value by hydraulic control system regulation and control clutch, can make clutch friction plate be in the sliding state that rubs, thereby the dead slow speed that realizes the boats and ships propeller is rotated, and has improved the stability that boats and ships locate or increased boats and ships the Security when pulling in to shore in flowing water.
Input described in the utility model, transmission, three parts of output all can be extracted out and be keeped in repair from behind not changing under motor and the situation that preceding casing connects.
