Planet wheel transmission device with gear limiting unhooking structure

Abstract

The invention discloses a planet wheel transmission device with a gear limiting unhooking structure. The planet wheel transmission device with the gear limiting unhooking structure comprises a gear sleeve, wherein a power source mechanism is arranged in the gear sleeve; a transmission mechanism is arranged at one end of the gear sleeve; an ice breaking mechanism is arranged at the other end of thetransmission mechanism; the power source mechanism comprises a power shaft; a first sun gear, a second sun gear and a third sun gear are arranged on the surface of the power shaft; a first planet setis arranged on the surface of the first sun gear; a second planet set is arranged on the surface of the second sun gear; a third planet set is arranged on the surface of the third sun gear; the diameter of the first sun gear is larger than the diameter of the second sun gear; the diameter of the second sun wheel is larger than the diameter of the third sun wheel; the first planet set comprises afirst supporting plate; a plurality of first planet gears are connected to one side of the first supporting plate through bearings; and the second planet set comprises a second supporting plate. The planet wheel transmission device with the gear limiting unhooking structure provided by the invention has the characteristics of high practicability and capability of automatically adjusting the working rotating speed.

Description

technical field [0001] The invention relates to the technical field of planetary gear transmission, in particular to a planetary gear transmission with a gear limiting and decoupling structure. Background technique [0002] Antarctica is a continent covered by ice and snow for a long time, which is rich in mineral resources. Since the 1760s, countries all over the world have been competing to explore and investigate Antarctica. In 1985, China officially sent a scientific research ship to Antarctica for investigation and established the Great Wall of China in Antarctica. In 1989, the Antarctic Zhongshan Station was established. Drilling is one of the important methods of Antarctic investigation; [0003] When drilling the ice layer, due to the different freezing time of the ice layer, the hardness of different ice layers will be different. However, in the existing drilling equipment, only the same speed can be maintained for drilling, and the personnel cannot timely understan...

[0003] When drilling the ice layer, due to the different freezing time of the ice layer, the hardness of different ice layers will be different. However, in the existing drilling equipment, only the same speed can be maintained for drilling, and the personnel cannot timely understand the position of the drill bit. The hardness of the ice layer at the location, so that the drilling rig may be overloaded when encountering the ice layer with high hardness, and the power of the drilling rig will be idle and the work efficiency will be reduced when encountering the ice layer with low hardness. It is necessary to design a planetary gear transmission with a gear limit decoupling structure that is practical and can automatically adjust the working speed
