It is also a kind of most widely used mud motor.Helicoid hydraulic motor is mainly by by-passing valve, stator, rotor, universal axle assembly, biography
The composition such as moving axis assembly.Wherein driving-shaft assembly is one of important component of helicoid hydraulic motor, its service life determines helicoid hydraulic motor
Overall life, driving-shaft assembly is mainly used for transmitting bit pressure, torque, when a well is drilled using bit pressure is excessive or misoperation, lead
The thrust bearings damage in driving-shaft assembly is caused, transmission shaft " locking " is may result in and can not work normally, so as to cause
Drilling work can not be normally carried out, cause it is unnecessary make a trip, influence progress and increase cost.
The structure of driving-shaft assembly at present, by water cap, upper TC bearing moving-coil, upper TC bearing Jing Quan, positioning key, axle power bearing
Group, spacer, pressure-bearing set, semi-ring, lower TC bearing moving-coil, shell, lower TC bearing Jing Quan and transmission shaft composition.Thrust bearings upper end
It being contacted with upper TC bearing moving-coil and upper TC bearing Jing Quan, lower end is covered with pressure-bearing and spacer contacts, when something unexpected happened, transmission
Most weak thrust bearings will bear huge external force and damage in axle assembly.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and it is total to provide a kind of helicoid hydraulic motor buffering transmission shaft
At.
The present invention to achieve the above object, using following technical scheme: a kind of helicoid hydraulic motor buffering driving-shaft assembly,
Be characterized in that: including the quiet set of upper TC bearing, upper TC bearing move set, upper ripple spring, thrust bearings, shell, pressure-bearing set, lower wave spring,
Spacer, semi-ring, lower TC bearing Jing Quan, lower TC bearing moving-coil, transmission shaft；The left end of the upper TC bearing dynamic set and the transmission shaft
The dynamic set cooperation of connection, the upper quiet set of TC bearing and the upper TC bearing, the left end of the shell and the upper quiet set of TC bearing
Connection, the thrust bearings are mounted between the transmission shaft and the shell, and the upper ripple spring is mounted on the upper TC axis
It holds between set and the left end of the thrust bearings and cooperates with the two, the pressure-bearing set is mounted on the thrust bearings
The right end of right end, pressure-bearing set is connect with the semi-ring, and the spacer is covered in the outside of the semi-ring and pressure-bearing set, under described
Wave spring is mounted on the right end of the spacer Yu the thrust bearings, the right end company of the lower TC bearing Jing Quan and the shell
It connects, the lower TC bearing Jing Quan and the lower TC bearing moving-coil cooperate, the right end of lower the TC bearing moving-coil and the transmission shaft
Connection.
The beneficial effects of the present invention are: compared with the existing technology, the buffering that the present invention forms top wave spring with upper and lower two
Group contacts the upper and lower ends of thrust bearings respectively.By way of increased buffering wave spring group and thrust bearings cooperation, make
The bearing group for obtaining weak link can be protected when receiving huge external force, so that damage is reduced to minimum.
Detailed description of the invention
