Abstract
A power three-branch transmission device for two-engine incoporation is characterized in that a primary input small gear is simultaneously meshed with two primary big gears, the two primary big gears drive secondary small gears through torsion shafts respectively, the two secondary small gears are simultaneously meshed with a secondary big gear, power is output through the secondary big gear, and therefore two power branches are formed; in addition, an ordinary gear train is arranged on the end portion of the primary input small gear, the ordinary gear train carries out input through a sun wheel and carries out output through an inner gear ring, the inner gear ring of the ordinary gear train is connected with a middle secondary small gear, the middle secondary small gear is also meshed with the secondary big gear, and a third power branch is formed. The power three-branch transmission device has the advantages that design is ingenious, and the structure is reasonable; input shafts and an output shaft are not coaxial, the three small gears meshed with an output big gear only occupy a small part of the circumference of the output big gear, and therefore the power three-branch transmission device can be used for double input and single output, namely, an engine incoporation transmission device, and the power three-branch engine incoporation transmission device is formed.
Description
technical field:
The present invention relates to mechanical equipment technical field, refer in particular to a kind of three branch's transmission devices of the power for two-shipper car.
background technique:
The two-shipper compounding transmission is that the power of two input shaft inputs is merged to an output shaft drive, the multiplex high speed heavy-load gear boxes such as main reducing gear in the large ship main power system of this transmission device at present.Two-shipper car can provide very high-power for propeller cavitation, simultaneously because the propeller for vessels rotating speed reduces gradually, make the velocity ratio of transmission device higher.Transmitted power is large, output speed is low, cause exporting the gearwheel load very high, for reducing gear loading, use the mode of branched power: the two branches of power commonly used machine is that input power is divided into to two parts, by two transmission branches, transmitted, the small gear of last each branch all with the engagement of output gearwheel, by power concentration to output shaft.Use the branched power structure, the load of reduction output gearwheel that can be at double, not only improved the operating conditions of output gearwheel, can also make the transmission device miniaturization.Visible, the quantity of branched power gear loading more at most is lower, and the present invention program can be increased to branched power quantity three.
summary of the invention:
The purpose of this invention is to provide a kind of three branch's transmission devices of the power for two-shipper car, meet the requirement of the two main frame inputs of heavily loaded big speed ratio gear-box needs and use branched power structure.
The objective of the invention is to realize as follows: a kind of three branch's transmission devices of the power for two-shipper car, mainly by gear, axle, mechanism's support body, formed, it is characterized in that: input one-level small gear meshes with two one-level gearwheels simultaneously, two one-level gearwheels drive the secondary small gear by torsion shaft respectively, two secondary small gears mesh with the secondary gearwheel simultaneously, by secondary gearwheel output power, two branched powers have so just been formed; In addition, in input one-level pinion-end, a fixed shaft gear train is installed, this fixed shaft gear train is the output of sun gear input ring gear, and the ring gear of fixed shaft gear train and middle secondary small gear link, middle secondary small gear also meshes with the secondary gearwheel, forms the 3rd branched power; One of them transmission branch is coaxial with input one-level small gear, with input one-level pinion-end, link, through the fixed shaft gear train coupling turn to rotating speed after drive the middle secondary small gear of this branch; Input one-level small gear meshes with two one-level gearwheels simultaneously, and two one-level gearwheels respectively link with a secondary small gear; In fixed shaft gear train, sun gear is identical with the gear ratio of input one-level small gear and one-level gearwheel with the gear ratio of ring gear, and in the middle of making like this, the secondary small gear is identical with other two secondary small gear rotating speeds; The sun gear of fixed shaft gear train links with input one-level small gear, and ring gear and middle secondary small gear link, and in the middle of making like this, the secondary small gear turns to identical with other two secondary small gears.
The invention has the beneficial effects as follows, design ingenious, rational in infrastructure; Input shaft and output shaft disalignment, only account for the sub-fraction circumferential position of output gearwheel with three small gears of output gearwheel engagement, so can be used for double input, single output,, in compounding transmission, forms power three branch's compounding transmissions.
