Description
Technical field
What the present invention relates to is a kind of gear drive of large speed ratio, mainly be applicable to have down, along clutch function and having than big retarding than (13 ~ 25:1) marine gearbox belongs to ship power transmission system field.
Background technique
At present, recognize that from relevant disclosed technical information channel the drive mechanism of at present relevant with the present invention marine gearbox mainly contains two kinds; Wherein a class formation adopts double reduction when ahead running; Three pairs of gear engagement during reversing are because total reduction ratio is big, so the single-stage reduction speed ratio is also bigger; Gear engagement poor quality, machine volume, weight are all bigger; Clutch is at high speed shaft, though that clutch can design is less, mounting or dismounting are difficult for, and particularly reduction speed ratio surpasses 16:1, and transmission capacity is decayed rapidly; Clutch moment of torsion on the second level is bigger, increases product cost greatly.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing technology exists, and a kind of large speed ratio marine gearbox that can effectively solve the existing defective of existing structure is provided.Its is on the one hand with smaller volume, and less weight reaches bigger transmission capacity, simultaneously gear engagement be improved significantly, be convenient to manufacturing and assembling maintenance again.
The objective of the invention is to accomplish through following technological scheme, it mainly is made up of input block, ahead running spindle unit, reverse shaft parts, intermediate shaft part, output block and box part; Hot jacket has the input gear on the input shaft of described input block, and the ahead running driving gear engagement of hot jacket on the ahead running axle of this input gear and ahead running spindle unit is equipped with the ahead running ahead running clutch of clutch housing gear of band on the ahead running axle of ahead running spindle unit; Described reverse shaft parts comprise the reverse clutch of reverse shaft, band reverse clutch shell gear; Also be equipped with the ahead running driving gear and reversing driving gear that link to each other with reverse clutch with the ahead running clutch on said ahead running axle and the reverse shaft respectively, and above-mentioned ahead running driving gear and reversing driving gear again respectively with the jack shaft of intermediate shaft part on the intermediate drive gear engagement that is connected; The middle driving gear of the output gear of hot jacket engagement on the output shaft that also is fixed with on the said jack shaft with output block; Described jack shaft is a quill shaft, and the jack shaft of this hollow is nested with on said input shaft and uses bearings.
The present invention adopts increase step of reduction (2 grades of decelerations increase to 3 grades of decelerations) in order to improve the gear engagement quality; Reducing the method for single staged transmission ratio, is more general method, but generally will cause product structure complicacy, size to increase owing to increase the one-level transmission; Manufacture difficulty strengthens; The present invention's core is passed input shaft for jack shaft is designed to hollow shaft from jack shaft, promptly input shaft and jack shaft are concentric; Such advantage is: the one. shorten the product axial dimension, reduce volume, weight; The 2nd, be convenient to the casing subdivision, installation and maintenance are convenient; The 3rd, convenient processing and manufacture; The 4th, carry lubricating oil pump and be installed on input shaft, can obtain less oil suction height; It has, and gear engagement is effectively improved (spot corrosion, gummed fault obviously reduce), assembling is easy to maintenance, and is different according to reduction speed ratio, characteristics such as net weight minimizing 20%～30%.

Embodiment
To combine below accompanying drawing to the present invention make detailed introduction: Fig. 1, shown in 2, the present invention mainly is made up of input block 1, ahead running spindle unit 2, reverse shaft parts 3, intermediate shaft part 4, output block 5 and box part; Hot jacket has input gear 12 on the input shaft 11 of described input block 1; Ahead running driving gear 22 engagements of hot jacket are equipped with the ahead running ahead running clutch 24 of clutch housing gear 23 of band on the ahead running axle 21 of this input gear 12 and ahead running spindle unit 2 on the ahead running axle 21 of ahead running spindle unit 2; Described reverse shaft parts 3 comprise the reverse clutch 33 of reverse shaft 31, band reverse clutch shell gear 32; Also be equipped with the ahead running driving gear 25 and reversing driving gear 34 that link to each other with reverse clutch 33 with ahead running clutch 24 on said ahead running axle 21 and the reverse shaft 31 respectively, and above-mentioned ahead running driving gear 25 and reversing driving gear 34 again respectively with the jack shaft 41 of intermediate shaft part 4 on intermediate drive gear 42 engagements that are connected; The middle driving gear 43 of output gear 52 engagements of hot jacket on the output shaft 51 that also is fixed with on the said jack shaft 41 with output block 5; Described jack shaft 41 is a quill shaft, and the jack shaft of this hollow 41 is nested with on said input shaft 11 and uses bearings.Be connected with profit oil pump 6 on the other end of described input shaft 11.
Power transmission principle of the present invention is:
Ahead running: input coupling → input shaft 11 → gear pair (input gear 12, ahead running driving gear 22) → ahead running axle 21 → ahead running clutch 24 → gear pairs (ahead running driving gear 25, intermediate drive gear 42) → jack shaft 41 → gear pair (middle driving gear 43, output gear 52) → output shaft 51 → output.
Reversing: input coupling → input shaft 11 → gear pair (input gear 12, ahead running driving gear 22) → ahead running axle 21 → gear pair (ahead running clutch housing gear 23, reverse clutch shell gear 32) → reverse shaft 31 → reverse clutch 33 → gear pair (reversing driving gear 34, intermediate drive gear 42) → jack shaft 4 → gear pair (middle driving gear 43, output gear 52) → output shaft 51 → output.
