Problems solved by technology
[0002] The motor shaft of the existing drilling motor uses a hollow shaft to guide the coolant to the drill bit. It is introduced from the rear of the hollow shaft and comes out from the front of the hollow shaft. However, there are usually the following problems: First, it is easy to fit the shaft Wear and tear, resulting in water leakage, which is easy to affect the motor; the second is the need for a water-through rotary joint

Embodiment Construction
[0015] Please refer to the figure, the present invention provides a technical solution:
[0016] This diversion structure for drilling motors includes a motor housing 1, a motor shaft 3 and an inlay block 2. The inlay block 2 is embedded in the front of the motor housing 1. It is characterized in that the inlay block 2 is provided with surrounding The first groove 2.1 of the motor shaft 3; the first groove 2.1 forms a closed space after the insert block 2 and the motor shaft 3 are matched, and several first blind holes 3.1 are opened on the peripheral wall of the motor shaft 3; There is a second blind hole 3.2 on the axis; the second blind hole 3.2 communicates with the first blind hole 3.1; when the motor shaft 3 rotates, the first blind hole 3.1 and the first slot 2.1 are always connected, and the outer wall of the motor housing 1 There is a water injection hole 1.2 in communication with the first groove 2.1, an oil seal 4 is installed between the motor shaft 3 and the motor...

The invention belongs to the field of motors, and particularly relates to a flow guide structure for a drilling motor, the flow guide structure comprises a motor shell, a motor shaft and an embedded block, the embedded block is embedded in the front part of the motor shell, and the embedded block is provided with a first groove surrounding the motor shaft; the first groove forms a closed space after the embedded block is matched with the motor shaft, and a plurality of first blind holes are formed in the circumferential wall of the motor shaft; a second blind hole is formed in the axis of the motor shaft; the second blind hole is communicated with the first blind hole; when the motor shaft rotates, the first blind hole is always communicated with the first groove, a water injection hole is formed in the outer wall of the motor shell and is communicated with the first groove, and an oil seal is arranged on the right side of the embedded block and is installed between the motor shaft and the motor shell. When the motor shaft and the motor shell are worn, the leaked cooling liquid cannot flow back to the stator and the rotor to influence the motor, and the cooling of the additionally rotating drill bit is facilitated; and secondly, the disassembly and assembly are convenient.
Description
technical field [0001] The invention belongs to the field of motors, in particular to a flow guide structure for drilling motors. Background technique [0002] The motor shaft of the existing drilling motor uses a hollow shaft to guide the coolant to the drill bit. It is introduced from the rear of the hollow shaft and comes out from the front of the hollow shaft. However, there are usually the following problems: First, it is easy to fit the shaft Wear and tear, resulting in water leakage, which is easy to affect the motor; the second is the need for a water-through rotary joint. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the assembly and shaft fit will not affect the motor after wear and tear, and the installation is convenient. The present invention proposes a flow guide structure for the drilling motor. [0004] In order to achieve the above object, the present invention adopts the following technical solutions...
