Description
Technical Field
The utility model belongs to the field of machinery, concretely relates to novel shunting high-speed gear box.
Background
As is well known, the high-speed gearbox is mainly applied to matching of units such as a ship propeller gearbox and the like. The highest rotating speed reaches 8000-plus 12000r/min, the maximum power reaches 20000-plus 40000KW, the gear precision reaches ISO4-5 level, and the gear dynamic balance precision reaches ISO 0.4-1.6. Due to the process requirement, the herringbone tooth tool withdrawal groove of the traditional high-speed gearbox in China is wider, and the size of the gearbox is relatively larger. With the development of economy and the advancement of technology, products with compact structure and more stable performance are increasingly required.
Disclosure of Invention
The utility model aims to provide a: a novel shunting high-speed gear box is designed, so that the structure is compact, the performance is stable, and the installation and the use are reliable.
The technical solution of the utility model is that: the split-flow type high-speed gear box comprises two high-speed shafts, a box body and a low-speed shaft, wherein two ends of the high-speed shafts are respectively installed on the box body through high-speed shaft sliding bearings, two ends of the low-speed shaft are respectively installed on the box body through low-speed shaft sliding bearings, a large gear is installed on the low-speed shaft through a key and is respectively meshed with the two high-speed shafts, and the high-speed gear box is integrally formed.
Wherein, install thrust disc axial location on the low-speed axle.
Wherein, the high-speed gear box adopts herringbone tooth reposition of redundant personnel structure.
The herringbone teeth adopt a small tool withdrawal groove structure, the machining center mills the tooth shape, and the tooth shape part is repaired in a drum shape.
The utility model has the advantages of it is following: 1. a flow dividing structure is adopted, so that the load of the gear is reduced by half; 2. the herringbone tooth structure with the small tool withdrawal groove is adopted, the structure is compact, the high-speed shaft is uniformly heated, the deformation is small, and the acceleration or deceleration transmission is met; 3. the tooth-shaped part is subjected to drum shape modification, the gear can run at a high speed with the linear speed of more than 100m/s, the performance is reliable, and the running is stable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the bearing comprises a large gear 1, a sliding bearing 2, a low-speed shaft 3, a sliding bearing II 4, a high-speed shaft 5, a box 6, a thrust disc 7, a key 8 and a high-speed shaft 9.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, which disclose, without limitation, specific configurations of embodiments of the present invention.
As shown in figure 1, the high-speed gear box comprises a first high-speed shaft 5, a second high-speed shaft 9, a box body 6 and a low-speed shaft 3, wherein two ends of the first high-speed shaft 5 and the second high-speed shaft 9 are respectively installed on the box body 6 through a second sliding bearing 4, two ends of the low-speed shaft 3 are respectively installed on the box body 6 through a first sliding bearing 2, a large gear 1 is installed on the low-speed shaft 3 through a key 8, and the large gear 1 is respectively meshed with the first high-speed shaft 5 and the second high-speed shaft 9, so that the novel split-flow high-speed gear box is integrally formed.
Wherein, the thrust disc 7 is arranged on the low-speed shaft 3 for axial positioning.
Wherein, the high-speed gear box adopts herringbone tooth reposition of redundant personnel structure.
The herringbone teeth adopt a structure of a small tool withdrawal groove, and the tooth-shaped parts of the herringbone teeth adopt drum-shaped modification.
