Abstract
The utility model relates to a locking device used for a radial bearing static ring of a drive shaft of a spiral drilling rig, which is applied to oil screw drill rigs. A shaft sleeve body is cylindrical, one end surface thereof is an annular plane, the other end thereof is evenly distributed with 2-6 fan-shaped bosses, and a fan-shaped groove is distributed between every two fan-shaped bosses. The locking device has the effects of capability of realizing radial connection between the radial bearing static ring and the shell of the driving shaft and prevention of relative movement between the two, without generating axial force. The reliable connection between the radial bearing static ring and the shell of the driving shaft is realized in a narrow space. The structure is simple and reliable and the occupation space is small.
Description
Technical field
The utility model relates to oil drilling equipment technology field, particularly a kind of down-hole helicoid hydraulic motor.The utility model is the quiet circle locking device of a kind of radial bearing in the screw drill transmission shaft assembly.
Background technique
At present, helicoid hydraulic motor is a most widely used mud motor in current oil, the gas drilling, not only indispensable in directional well, horizontal well drilling operation, and along with the popularization of compound brill, helicoid hydraulic motor becomes the indispensable downhole tool of full well section speed-raising just gradually.Helicoid hydraulic motor mainly is made up of by-pass valve assembly, motor assembly, cardan shaft assembly, driving-shaft assembly four parts.Driving-shaft assembly mainly comprises parts such as transmission shaft, housing, thrust bearings, upper and lower radial bearing group, water cap at the foot of helicoid hydraulic motor.The effect of driving-shaft assembly mainly is to transmit Operating torque; Thrust bearings and radial bearing group are carried axial, the radial load in the drilling engineering respectively.The radial bearing overcoat generally is locked together by form such as screw thread, key, pin and transmission shaft shell, does not allow to relatively rotate between mutually in the working procedure.
The model utility content
The purpose of this utility model is: a kind of screw drill transmission shaft radial bearing Jing Quan locking device is provided, and realization radial bearing Jing Quan is connected with transmission shaft shell, plays preventing that both from acting in relative rotation.In narrow space, realize reliable connection the between radial bearing Jing Quan and the transmission shaft shell.
The technical solution adopted in the utility model is: screw drill transmission shaft radial bearing Jing Quan locking device, form by sleeve body, it is characterized in that: sleeve body is cylindric, an end face of sleeve body is the ring plane, the other end at sleeve body is evenly distributed with 2～6 fan-shaped projectioies, and a scalloped recess is arranged between two fan-shaped projectioies.
For stressed even.Described fan-shaped projection is identical with the angle of the angle of circumference of scalloped recess.
Screw drill transmission shaft radial bearing Jing Quan welds together with sleeve body one end and the transmission shaft shell of locking device.Radial bearing quiet circle one end fixing at needs also processes fan-shaped projection and the scalloped recess that matches with it.In assembling time,, screw drill transmission shaft radial bearing Jing Quan is enclosed within on the axle simultaneously with locking device and radial bearing Jing Quan, and is embedded in (the projection reeve locking device scalloped recess of radial bearing Jing Quan is interior) together mutually.By the utility model locking device, realize being connected of bearing Jing Quan radially and transmission shaft shell prevented that both from relatively rotating.When moving axially between radial bearing Jing Quan and the transmission shaft shell, fan-shaped projection and scalloped recess by the phase embedding can not produce axial force.
The beneficial effects of the utility model: the utility model screw drill transmission shaft radial bearing Jing Quan locking device, realized being connected of radial bearing Jing Quan and transmission shaft shell, prevent to relatively rotate between the two; And can not produce axial force.In narrow space, realize reliable connection the between radial bearing Jing Quan and the transmission shaft shell.
Description of drawings
Fig. 1 is the utility model screw drill transmission shaft radial bearing Jing Quan locking device structure schematic perspective view.
Among the figure, 1. sleeve body, 2. fan-shaped projection, 3. scalloped recess.
Embodiment
Embodiment 1: with a screw drill transmission shaft radial bearing Jing Quan locking device is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model screw drill transmission shaft radial bearing Jing Quan locking device is made up of sleeve body 1.Sleeve body 1 is 100 millimeters of cylindric internal diameters, 120 millimeters of external diameters, an end face of sleeve body 1 is the ring plane, is evenly distributed with two fan-shaped protruding 2 at the other end of sleeve body 1, between two fan-shaped protruding 2, a scalloped recess 3 is arranged, promptly have two scalloped recess 3.Fan-shaped protruding 2 is identical with the angle of the angle of circumference of scalloped recess 3.The degree of depth of scalloped recess 3 is 20 millimeters.
Claims (2)
