Detailed Description
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in fig. 1, a screw-based cam oscillator includes a transmission spindle 1, an upper joint 2, a transmission housing 3, a middle sleeve 4, a disc spring 5, a spindle joint 6, a piston 7, a half ring 8, a cam seat 9, a cam 10, a roller 11, a roller seat 12, a housing 13, a flexible shaft 14, a stator 15, a rotor 16 and an adapter 17.
The upper joint, the transmission shell and the middle sleeve are sequentially connected, the transmission mandrel is arranged in the transmission shell, the disc spring is arranged between the middle sleeve and the transmission mandrel, the piston is arranged between the mandrel joint and the middle sleeve, the cam is arranged on the mandrel joint through the cam seat and the semi-ring, the roller is arranged on the roller seat and is arranged at one end of the shell, the other end of the shell is connected with the stator, the rotor is located in the stator, one end of the rotor is connected with the transmission mandrel through the flexible shaft, and the conversion joint is connected with one end of the stator. Preferably, the middle part of the transmission mandrel is of a hollow structure.
The middle part of the transmission mandrel is of a hollow structure. For the slurry to pass through.
The middle part of the flexible shaft is of a hollow structure. For the slurry to pass through.
The rotor is of a hollow structure. For the slurry to pass through.
Drilling mud enters an upper oscillation system through a mud pump, passes through an inner hole of a mandrel of the oscillation system, enters a stator and a rotor of a motor, the rotor performs planetary motion in the stator under the action of the mud, the planetary motion is converted into fixed shaft motion through a flexible shaft, so that a cam seat 12 and a roller 11 are driven to rotate, the cam is driven to perform reciprocating motion under the action of the roller, the reciprocating motion is transmitted to a disc spring 5 through a mandrel joint 6, axial vibration is generated on a transmission mandrel 1 and an upper joint 2, static friction force between a downhole drill string and a well wall is converted into dynamic friction force, and accordingly the pressure supporting condition of the drill string is prevented.
In present drilling operation, for solving the pressure condition in the pit, also there are many this kind of instruments in the market, and all utilize the energy that the pressure of mud produced in the use, along with the influence of well depth and mud proportion, the pressure of some instruments is high, and drilling equipment can not satisfy, so can not use, and this use is novel to be realized through the cam structure, and the pressure that the instrument needs is low, can satisfy various operating mode conditions.
