Description

Technical Field

[0001] The utility model relates to the technical field of motor rotors, in particular to a disc-type submersible motor rotor. Background Art

[0002] The submersible motor rotor is an important part of the submersible motor, mainly composed of the rotor core, shaft, thrust bearing, upper joint and lower joint. The function of the submersible motor rotor is to convert electrical energy into mechanical energy, output through the motor shaft, and provide power for the submersible pump.

[0003] When an existing motor is working, friction occurs between the rotating shaft in the rotor and the motor, resulting in a reduction in the service life of the rotor. In order to reduce the problem of rotor wear, lubricating oil is usually applied to the rotating shaft in the rotor. However, when the motor rotor works for a long time, it is difficult for humans to detect the wear of the rotor in time and apply lubricating oil to the rotor, which reduces the service life of the motor rotor.

[0004] To this end, we propose a disc-type submersible motor rotor. Utility Model Content

[0005] The utility model aims to provide a disc-type submersible motor rotor to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disc-type submersible motor rotor, comprising a shell and a rotating shaft, a circular ring fixedly connected to the surface of the shell, a sliding frame slidably connected to the surface of the circular ring, a mounting seat fixedly connected to the surface of the sliding frame, a capsule bottle placed inside the mounting seat, a nozzle rotatably connected to the surface of the capsule bottle, a sliding rod slidably connected to the surface of the capsule bottle, one end of the sliding rod fixedly connected to a cover plate, an end of the sliding rod away from the cover plate fixedly connected to a support rod, one end of the support rod fixedly connected to a first ladder block, and the surface of the rotating shaft fixedly connected to a second ladder block.

[0007] The effects achieved by the above components are: first, the lubricating oil is introduced into the capsule bottle, and then the capsule bottle is placed in the mounting seat. At this time, the sliding frame on the circular ring is moved, and the sliding frame will drive the mounting seat and the capsule bottle to be directly above the rotating shaft. When the rotating shaft rotates, the second ladder block will rotate under the action of the rotating shaft. At this time, the second ladder block will contact the first ladder block and squeeze the first ladder block to move upward. At this time, the sliding rod and the support rod will drive the cover plate to move under the action of the first ladder block. At this time, the lubricating oil can drip onto the rotating shaft through the nozzle, thereby facilitating the lubrication of the rotating shaft and reducing the problem of wear on the rotating shaft in the rotor.

[0008] Preferably, an insertion rod is slidably connected to the surface of the sliding frame, a plurality of circular holes are provided on the surface of the circular ring, and the insertion rod is snap-fitted with the circular ring on the surface of the circular ring.

[0009] The effect achieved by the above components is: at this time, the insertion rod is pushed into the ring, thereby improving the stability of the mounting seat and facilitating the operation of the capsule bottle.

[0010] Preferably, a limiting ring is fixedly connected to the surface of the capsule bottle, and the limiting ring is threadedly connected to the mounting seat.

[0011] The effects achieved by the above components are: the limiting ring on the rotating capsule bottle is connected to the mounting seat, thereby improving the stability of the capsule bottle and facilitating the replacement of the capsule bottle.

[0012] Preferably, the arc surface of the slide rod is sleeved with a spring, and two ends of the spring are fixedly connected to the capsule bottle and the slide rod respectively.

[0013] The effect achieved by the above components is: when the slide rod moves upward, it will drive the spring to stretch. When the second ladder block moves away from the first ladder block, the spring tension can drive the cover plate on the slide rod to reset, thereby facilitating the sealing of the lubricating oil and preventing the lubricating oil from dripping for a long time.

[0014] Preferably, a ball is rotatably connected to the surface of the first ladder block, and the ball is a spherical structure.

[0015] The effect achieved by the above components is that the setting of the ball bearings can effectively improve the sliding effect between the first ladder block and the second ladder block, and reduce the problem of jamming between the first ladder block and the second ladder block.

[0016] Preferably, a smear block is placed on the surface of the nozzle, and the smear block is a sponge block.

[0017] The effect achieved by the above components is: the smear block is placed on the nozzle, and the setting of the smear block can effectively improve the smearing effect on the rotating shaft.

[0018] Preferably, a plurality of sharp protrusions are fixedly connected to the surface of the nozzle, and the sharp protrusions are of a conical structure.

[0019] The effect achieved by the above-mentioned components is that the pointed protrusion will contact with the smear block and be inserted into the smear block, thereby improving the stability of the smear block and facilitating the regular replacement of the smear block.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] See also Figure 1-5 The utility model provides a technical solution: a disc-type submersible motor rotor, including a shell 1 and a rotating shaft 2.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] like Figure 1-Figure 5As shown, a circular ring 3 is fixedly connected to the surface of the shell 1, a sliding frame 4 is slidably connected to the surface of the circular ring 3, a mounting seat 6 is fixedly connected to the surface of the sliding frame 4, a capsule bottle 7 is placed inside the mounting seat 6, a nozzle 9 is rotatably connected to the surface of the capsule bottle 7, a sliding rod 12 is slidably connected to the surface of the capsule bottle 7, one end of the sliding rod 12 is fixedly connected to a cover plate 13, one end of the sliding rod 12 away from the cover plate 13 is fixedly connected to a support rod 15, one end of the support rod 15 is fixedly connected to a first ladder block 16, and a second ladder block 18 is fixedly connected to the surface of the rotating shaft 2. First, lubricating oil is introduced into the capsule bottle 7, and then the capsule bottle 7 is placed in the mounting seat 6. At this time, the sliding frame 4 on the ring 3 is moved, and the sliding frame 4 will drive the mounting seat 6 and the capsule bottle 7 to the top of the rotating shaft 2. When the rotating shaft 2 rotates, the second ladder block 18 will rotate under the action of the rotating shaft 2. At this time, the second ladder block 18 will contact with the first ladder block 16 and squeeze the first ladder block 16 to move upward. At this time, the sliding rod 12 and the support rod 15 will drive the cover plate 13 to move under the action of the first ladder block 16. At this time, the lubricating oil can drip onto the rotating shaft 2 through the nozzle 9, thereby facilitating the lubrication of the rotating shaft 2 and reducing the problem of wear of the rotating shaft 2 in the rotor. The surface of the sliding frame 4 is slidably connected with the insertion rod 5, and the surface of the ring 3 is provided with a plurality of circular holes, and the insertion rod 5 is clamped with the ring 3 on the surface of the ring 3. At this time, the insertion rod 5 is pushed into the ring 3, thereby improving the stability of the mounting seat 6 and facilitating the work of the capsule bottle 7. The surface of the capsule bottle 7 is fixedly connected with a limit ring 8, and the limit ring 8 is threadedly connected with the mounting seat 6. The limit ring 8 on the rotating capsule bottle 7 is connected with the mounting seat 6, thereby improving the stability of the capsule bottle 7 and facilitating the replacement of the capsule bottle 7. The arc surface of the slide bar 12 is covered with a spring 14, and the two ends of the spring 14 are fixedly connected with the capsule bottle 7 and the slide bar 12 respectively. When the slide bar 12 moves upward, it will drive the spring 14 to extend. When the second ladder block 18 is away from the first ladder block 16, the tension of the spring 14 can drive the cover plate 13 on the slide bar 12 to reset, thereby facilitating the sealing of the lubricating oil and avoiding the lubricating oil from dripping for a long time. The surface of the first ladder block 16 is rotatably connected with a ball 17, and the ball 17 is a spherical structure. The setting of the ball 17 can effectively improve the sliding effect between the first ladder block 16 and the second ladder block 18, and reduce the problem of jamming between the first ladder block 16 and the second ladder block 18. A smear block 11 is placed on the surface of the nozzle 9, and the smear block 11 is a sponge block. The smear block 11 is placed on the nozzle 9, and the setting of the smear block 11 can effectively improve the smearing effect on the rotating shaft 2. A plurality of sharp protrusions 10 are fixedly connected to the surface of the nozzle 9, and the sharp protrusions 10 are cone structures. The sharp protrusions 10 will contact with the smear block 11 and insert into the smear block 11, thereby improving the stability of the smear block 11 and facilitating the regular replacement of the smear block 11.

[0032] Working principle: When the motor rotor is working, firstly, lubricating oil is introduced into the capsule bottle 7, then the capsule bottle 7 is placed in the mounting seat 6, and the limiting ring 8 on the capsule bottle 7 is rotated to connect with the mounting seat 6, thereby improving the stability of the capsule bottle 7 and facilitating the replacement of the capsule bottle 7. At this time, the smear block 11 is placed on the nozzle 9, and the pointed protrusion 10 will contact with the smear block 11 and be inserted into the smear block 11, thereby improving the stability of the smear block 11 and facilitating the regular replacement of the smear block 11. At this time, the moving circle The slide frame 4 on the ring 3 will drive the mounting seat 6 and the capsule bottle 7 to the top of the rotating shaft 2. At this time, the insertion rod 5 is pushed into the ring 3, thereby improving the stability of the mounting seat 6 and facilitating the capsule bottle 7 to work. When the rotating shaft 2 rotates, the second ladder block 18 will rotate under the action of the rotating shaft 2. At this time, the second ladder block 18 will contact the first ladder block 16 and squeeze the first ladder block 16 to move upward. At this time, the slide bar 12 and the support rod 15 will drive the cover plate 13 to move forward under the action of the first ladder block 16. The lubricating oil can be dripped onto the rotating shaft 2 through the nozzle 9 at this time, thereby facilitating the lubrication of the rotating shaft 2 and reducing the problem of wear of the rotating shaft 2 in the rotor. The setting of the smearing block 11 can effectively improve the smearing effect of the rotating shaft 2. When the second ladder block 18 is away from the first ladder block 16, the tension of the spring 14 can drive the cover plate 13 on the slide bar 12 to reset, thereby facilitating the sealing of the lubricating oil and avoiding the long-term dripping of the lubricating oil. The setting of the ball 17 can effectively improve the sliding effect between the first ladder block 16 and the second ladder block 18, and reduce the problem of jamming between the first ladder block 16 and the second ladder block 18. By setting the capsule bottle 7, the nozzle 9, the limit ring 8, the spring 14, the first ladder block 16 and the second ladder block 18, the lubricating effect of the motor rotor is improved, the wear of the rotating shaft 2 in the motor rotor is reduced, and the problem of reduced service life of the motor rotor is caused, which facilitates the replacement of the capsule bottle 7 and further improves the practicality of the motor rotor.
