Coaxial all-metal cam stator and rotor underground dynamical drilling tool

Abstract

A coaxial all-metal cam stator and rotor underground dynamical drilling tool comprises a transition joint, the transition joint is connected with a motor assembly through threads, and the motor assembly is connected with a transmission shaft assembly through threads. After being filtered through a filtering device, drilling liquid passes through the transition joint, enters an annular space between a motor base shell of an upper motor and a stator shell after passing through an upper end cover, enters a center hole of an upper rotor after acting on the upper rotor, is discharged towards a lower motor through inclined holes in the center hole of the upper rotor and continuously drives the lower motor to rotate, a part of the liquid acted by the lower motor flows out through small holes formed in a transmission shaft joint to lubricate and cool a bearing and most of the drilling liquid is sprayed out through an inner hole of a spindle of the transmission shaft and drill water holes so as to cool and clean a drill and circulate slurry. The coaxial all-metal cam stator and rotor underground dynamical drilling tool has the advantages of being resistant to abrasion, resistant to corrosion, resistant to high temperature, resistant to aging, long in service life, simple in structure and easy to machine.

AI Technical Summary

Benefits of technology

This patented technical effect described in this patents relieves pressure on workers who work at elevated levels for longer periods while also reducing their risk of experiencing health issues such as heat stress or other negative side reactions that may occur if they don't have enough time after exposure to these harsh environments.

Problems solved by technology

This patented problem addressed by this patents relates to improving the performance of lubricating systems for rotary tools that use elastomer bushings made from materials like silicone or fluoroelastic material due to their excellent properties at extreme temperatures and pressures. These bushings have several advantages over traditional methods: they are stronger than regular steel rings while also being less prone to leaks when subjected to severe environments. They can be easily adjustable without losing its effectiveness under different operating scenarios.
