Embodiment Construction

[0032] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0033] Such as Figure 1 to Figure 6 As shown, a motor two-speed automatic transmission for an underwater vehicle includes a casing 1 and an input shaft 2 , a transmission mechanism 3 , a shifting mechanism 4 and an output shaft 5 all installed in the casing 1 . Wherein, the box body 1 is cylindrical, which makes the overall structure more compact. The input shaft 2 and the output shaft 5 are arranged coaxially, and both extend along the axial direction of the box body 1 .

[0034] See Figure 1 ~ Figure 3 , the box body 1 includes a front box body 11 and a rear box body 12 arranged coaxially, the rear end of the front box body 11 is fixedly connected with the front end of the rear box body 12, wherein the shift operating mechanism 4 is located at the front Inside the box body 11 , a small part of the transmission mechanism 3 is located inside the front bo...

Abstract

The invention discloses a motor two-gear automatic transmission for an underwater diving device and a gear shifting method which comprises a box body and an input shaft, a transmission mechanism, a gear shifting control mechanism and an output shaft which are arranged in the box body, wherein the input shaft and the output shaft are coaxially arranged; and the transmission mechanism comprises aninner gear ring rotationally arranged on the input shaft and an n-stage planetary gear train arranged at one end of the input shaft, and each stage of the planetary gear train is provided with a planet carrier, a sun gear and m planetary gears. According to the motor two-gear automatic transmission for the underwater diving device and the gear shifting method, the structure is novel, and easy to realize, the size is small and compact, the transmission has a large transmission ratio (greater than 10), and achieves two-gear automatic speed change, so that the use and assembly requirements of theunderwater diving device can be met.

Description

technical field [0001] The invention belongs to the technical field of transmission systems, and in particular relates to a motor two-speed automatic transmission for an underwater vehicle and a gear shifting method. Background technique [0002] Underwater submersibles are mostly used for scientific research in areas such as underground water systems, above-ground rivers, and oceans. Submersibles are generally equipped with many modern high-tech marine instruments, and undertake data collection of various information such as geography and biology. [0003] Therefore, the space left by the underwater vehicle for its own power system is extremely limited, and because the underwater vehicle needs to adapt to a special working environment, it requires its own transmission system to have a large transmission ratio, usually requiring a transmission ratio of more than 10. [0004] The existing transmissions are difficult to meet the small size and large transmission ratio (greater...
