The device is technically characterized in that the input power of a main machine is transferred by engaging a one-stage input small gear with three one-stage output large gears at the same time; the output shaft of each one-stage output large gear is connected with the input shaft of each two-stage input small gear through a torque shaft; each two-stage input small gear is engaged with the two-stage output large gears at the same time; a two-stage output large gear shaft is provided with a thrusting bearing; circular disks are arranged on the two sides of the one-stage input small gear and the two-stage input small gear; the inside of each circular disk is chambered to form a conical surface; and a conical matching surface matched with the conical surface of each circular disk is respectively formed on the edges on the two sides of the one-stage output large gear and the two-stage output large gear engaged with each conical surface. By using the three-branch two-stage speed-reducing helical gear transmission device, the problems that the conventional helical gear transmission device is complex in lubricating system, complex in structure and instable in system are solved; the reliability of the gear device is improved; and therefore, the device can be widely applied to naval vessels and other fields.
Description
Technical field:
The invention belongs to gear drive, be specifically related to a kind of power peculiar to vessel three branch's double reduction screw-wheel gearings.
Background technique:
At present, boat transmission adopts the branched power structure more, and it is that dead axle is the gear-driven a kind of form of branch.The transmission of so-called gear branch is exactly that a gear is meshed with a plurality of gears simultaneously, realizes the transmitted power shunting, thereby has reduced gear loading, dwindle secondary gearwheel size, improves the specific power of transmission device.For traditional branched power gearing, because its gear shaft is many, therefore also need complicated gear shaft positioning bearing device, can produce end thrust during this outer oblique gear engagement, for eliminating end thrust, also need to assemble thrust balancing device, mostly existing thrust balancing device is thrust-bearing, its complex structure, this has just strengthened the complexity of transmission device, has seriously restricted the gearing application and development of branched power.And the installation procedure of thrust-bearing is loaded down with trivial details, wastes time and energy.
Summary of the invention:
The purpose of this invention is to provide a kind of power peculiar to vessel three branch's double reduction screw-wheel gearings, it has solved existing screw-wheel gearing lubrication system complexity, complex structure, the unsettled problem of system, has improved the reliability of gearing.
The objective of the invention is to realize in the following manner: these power three branch's double reduction screw-wheel gearings peculiar to vessel, the technological scheme that adopts is: comprise a primary input axial, three one-level output shafts, three secondary input shafts and a secondary output shaft, three one-level output shafts connect with three secondary input shafts by torsion shaft respectively, primary input axial is provided with one-level input small gear, the one-level output shaft is provided with one-level output gearwheel, the secondary input shaft is provided with secondary input small gear, the secondary output shaft is provided with secondary output gearwheel, one-level on primary input axial input small gear simultaneously and the engagement of three one-levels output gearwheels, the secondary input small gear on three secondary input shafts is simultaneously and the engagement of a secondary output gearwheel; The both sides of one-level input small gear and secondary input small gear are equipped with circular discs, the inboard bevelling of circular discs forms the conical surface, be respectively equipped with the conical surface matching surface that the conical surface with circular discs matches respectively with on the both sides of the edge of the one-level output gearwheel of both engagements and secondary output gearwheel, be equipped with a thrust-bearing on the secondary output shaft.
Preferably, described three one-levels output gearwheel circumferentially evenly distributes as the axle center take the axis of one-level input small gear.
The invention has the beneficial effects as follows: these power three branch's double reduction screw-wheel gearings peculiar to vessel, by branched power is set, improved the practical reliability of power three branch inclined gear drives.The circular discs of setting up is as thrust balancing device, the end thrust that produces in the time of can solving simultaneously the alignment and balance meshed transmission gear of gear, compare with thrust-bearing, circular discs is simple in structure, be convenient to install, and because circular discs can be installed in the gear-box with gear, be convenient to like this circular discs is lubricated, the invention solves existing screw-wheel gearing lubrication system complexity, complex structure, the unsettled problem of system, improve the reliability of gearing, therefore can be widely used in naval vessel and other field.
