Description

A directional drive device Technical Field

[0001] The invention belongs to the technical field of directional drive devices, in particular to a directional drive device. Background Art

[0002] The directional drive is the center of shaft adjustment for rotating equipment. It uses a couple to drive the rotor of the passive equipment, ensuring a fully free state of operation and ensuring respectful work and shaft adjustment. It is designed to accurately measure the direction and value of shaft runout and standardize shaft adjustment using vector concepts. It consists of a directional drive, a couple, a coupling, and a drive component.

[0003] Since the dawn of hydropower history, shaft alignment of hydropower units has relied on manual labor. This has a critical drawback: it only measures and records the swing magnitude, but fails to calibrate its direction. Consequently, it's impossible to properly stagger the swings of individual units. This can lead to overlapping unit swings, causing cluster resonance and potentially damaging dams and hydraulic infrastructure. Furthermore, this method consumes significant manpower and power generation time. Workers are forced to repeat simple tasks under rigid time and space constraints, which in turn degrades their dignity and decency. This prolonged work schedule results in lost power generation time. Therefore, a directional drive device that can both accurately measure the swing magnitude and calibrate its direction is urgently needed.

[0004] To this end, the present invention provides a directional drive device. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a directional drive device described in the present invention includes a stationary part of a passive device, a hollow frame format bracket is fixedly installed on the top of the stationary part of the passive device, a reference plate is fixedly installed on the top of the reference plate, a directional base is fixedly installed on the top of the reference plate, a cover plate is fixedly installed on the top of the directional base, the top of the cover plate is connected to an adjusting wheel through a rotating component, a reducer is fixedly installed on the bottom of the reference plate, an output component is installed on the output end of the reducer, and the top of the hollow frame format bracket is rotatably connected to a steering wheel.

[0007] Furthermore, the output assembly includes a small gear fixedly mounted on the output end of the reducer, a large gear is rotatably connected to the bottom of the directional base, the large gear and the reference plate are matched by bearings, and the small gear passes through the reference plate and meshes with the large gear.

[0008] Furthermore, a driving groove is provided on the inner diameter side of the large gear, and a driving key is connected to the internal transmission of the driving groove. The driving key is installed on the coupling, and the rotor of the passive device is fixedly installed on the bottom of the coupling.

[0009] Furthermore, the rotating assembly includes an adjusting gear fixedly mounted on the adjusting wheel, the adjusting gear passes through the cover plate and engages with the steering wheel, a compass is fixedly mounted on the top of the steering wheel, and a pointer is fixedly mounted on the surface of the driving key.

[0010] Furthermore, the large gear has a large inner diameter and the coupling has a small outer diameter, thereby forming an air gap.

[0011] Furthermore, the coupling is threadedly connected with a centering bolt in the radial direction.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The directional drive device described in the present invention is fixed to the stationary part of the passive equipment through a hollow frame bracket, and the adjusting wheel is rotated to drive the adjustment gear, which is engaged with the steering wheel. Through the rotation of the steering wheel, the zero scale of the steering wheel coincides with the north direction of the compass, and the indicated direction of the pointer coincides with the zero scale of the steering wheel. When the pointer moves, the direction (angle) of movement is displayed.

[0014] The gearwheel is mounted on a datum plate with bearings, and the center distances of the gearwheel and pinion are aligned on the same datum plate. This ensures accurate data, streamlined construction, and avoids accumulated errors. It is reliable, safe, practical, and aesthetically pleasing. The same datum plate allows for the rational arrangement of the reducer and provides space for steering wheel operation. The horizontal and vertical contact surfaces between the gearwheel and the datum plate form the bearing, and the bearing surfaces are greased. A drive slot is located on the inner diameter of the gearwheel, while a drive key is secured to the outer diameter of the coupling. Adjustment bolts are used to uniformly adjust the air gap. The interaction between the drive slot and key drives the rotor of the passive device, causing it to rotate. At this point, the pointer corresponds to the azimuth of the steering wheel, which allows personnel to record the direction and value of the shaft system's swing at that moment. This eliminates the traditional manual drive process, optimizing the working environment and conditions, and ensuring dignified and respectful work.

[0015] 2. The directional drive device described in this invention combines the original lever arm and housing into a reference plate, centralizing the reducer positioning and the center distance between the large and small gears on the same reference plate. This effectively avoids cumulative errors and improves accuracy, playing a crucial role in achieving the national standard of "shaft system runout of no more than 0.02 mm per meter." Furthermore, the reducer is positioned below the reference plate, effectively protected by a hollow frame-like bracket, avoiding interference with the reducer and optimizing steering wheel operating conditions.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] As shown in Figures 1 to 6, a directional drive device described in an embodiment of the present invention includes a stationary part 19 of a passive device, a hollow frame format bracket 18 is fixedly installed on the top of the stationary part 19 of the passive device, a reference plate 8 is fixedly installed on the top of the reference plate 8, a directional base 7 is fixedly installed on the top of the directional base 7, a cover plate 6 is fixedly installed on the top of the cover plate 6, an adjusting wheel 2 is connected to the top of the cover plate 6 through a rotating component, a reducer 9 is fixedly installed on the bottom of the reference plate 8, an output component is installed on the output end of the reducer 9, and the top of the hollow frame format bracket 18 is rotatably connected to the steering wheel 4. The output assembly includes a small gear 10 fixedly mounted on the output end of the reducer 9, a large gear 11 is rotatably connected to the bottom of the directional base 7, the large gear 11 and the reference plate 8 are matched by a bearing 12, the small gear 10 passes through the reference plate 8 and engages with the large gear 11, a driving groove 13 is provided on the inner diameter side of the large gear 11, and a driving key 14 is rotatably connected inside the driving groove 13, and the driving key 14 is mounted on the coupling 15, and the rotor 20 of the passive device is fixedly mounted on the bottom of the coupling 15.

[0026] During operation, the original lever arm and housing are combined into a reference plate 8. The positioning of the reducer 9 and the center distance between the large gear 11 and the small gear 10 are centrally located on the same reference plate 8, effectively avoiding cumulative errors and improving precision. This is crucial for achieving the national standard of "adjusting the shaft system runout to no more than 0.02mm per meter." Furthermore, the reducer 9 is positioned below the reference plate 8 and effectively protected by a hollow frame bracket 18, avoiding interference from the reducer 9 and optimizing the operating conditions of the steering wheel 4.

[0027] The rotating assembly includes an adjustment gear 3 fixedly mounted on the adjustment wheel 2. The adjustment gear 3 passes through the cover plate 6 and meshes with the steering wheel 4. The top of the steering wheel 4 is fixedly mounted with a compass 1, and the surface of the drive key 14 is fixedly mounted with a pointer 5. The large gear 11 has a large inner diameter and the coupling 15 has a small outer diameter, thereby forming an air gap 17. The coupling 15 has a radial centering bolt 16.

[0028] During operation, the hollow frame bracket is fixed to the stationary part 19 of the passive equipment and rotates the adjustment wheel 2 to drive the adjustment gear 3. The adjustment gear 3 engages with the steering wheel 4. Through the rotation of the steering wheel 4, the zero scale of the steering wheel points to the north, which is verified by the compass 1. The large gear 11 is matched with the reference plate 8 by the bearing 12, and the center distance of the large gear 11 and the small gear 10 is positioned on the same reference plate 8. This not only accurately determines the data, but also simplifies the structure, avoids the accumulation of errors, is reliable and safe, and is practical, beautiful and uniform. The same reference plate 8 provides conditions for the reasonable layout of the reducer 9 and creates space for the operation of the steering wheel 4. The horizontal and vertical joint surfaces between the large gear 11 and the reference plate 8 constitute the bearing 12, and grease is applied between the two surfaces of the bearing 12. A driving groove 13 is provided on the inner diameter of the large gear 11, and a driving key 14 is fixed on the outer diameter of the coupling 15. The air gap 17 is adjusted to be uniform by the centering bolt 16. The driving groove 13 and the driving key 14 interact with each other to drive the rotor 20 of the passive device to rotate. At this time, the pointer 5 corresponds to the azimuth angle of the steering wheel 4. Based on this, the personnel will record the swing direction and swing value of the shaft system at this moment, thereby abandoning the original "track hauler" type manual drive process, optimizing the working environment, improving working conditions, and realizing dignified and decent work for personnel.

[0029] This designed structure provides direction for shaft system swing adjustment, shifting from a single scalar adjustment to simultaneous adjustment of both the direction and magnitude of the swing. This provides a basis for avoiding resonance and other hazards caused by overlapping swings. This structural solution thoroughly implements the principle of couples, and the hollow frame bracket 18 relieves tangential stress.

[0030] Working Principle: Rotating the steering wheel 4 causes the compass needle 1 to point north, aligning with the zero mark on the steering wheel 4. This causes the pointer 5 to correspond to the zero mark on the steering wheel 4, indicating zero drive. When the large gear 11 rotates, the drive slot 13 drives the drive key 14, which in turn drives the coupling 15, thereby driving the rotor 20 of the passive device. Pointer 5 then points to the direction mark on the steering wheel 4, achieving both the measurement of swing magnitude and the calibration of swing direction.

[0031] By combining the original lever arm and housing into a base plate 8, the positioning of the reducer 9 and the center distance between the large gear 11 and the small gear 10 are centralized on the same base plate 8, effectively avoiding cumulative errors and improving precision. This is crucial for achieving the national standard of "shaft system runout of no more than 0.02mm per meter." Furthermore, the reducer 9 is positioned below the base plate 8, effectively protected by a hollow frame bracket 18, avoiding interference from the reducer 9 and optimizing the operating conditions of the steering wheel 4.

[0032] The hollow frame bracket is fixed to the static part 19 of the passive device and rotates the adjustment wheel 2 to drive the adjustment gear 3. The adjustment gear 3 engages with the steering wheel 4. Through the rotation of the steering wheel 4, the compass 1 and the large gear 11 are matched on the reference plate 8 by the bearing 12. The center distance of the large gear 11 and the small gear 10 are positioned on the same reference plate 8. This not only accurately determines the data, but also simplifies the structure, avoids the accumulation of errors, is reliable and safe, and is practical, beautiful and uniform. The same reference plate 8 provides conditions for the reasonable arrangement of the reducer 9 and creates space for the operation of the steering wheel 4. The horizontal and vertical joint surfaces between the large gear 11 and the reference plate 8 constitute the bearing 12, and grease is applied between the two surfaces of the bearing 12. A driving groove 13 is provided on the inner diameter of the large gear 11, and a driving key 14 is fixed on the outer diameter of the coupling 15. The air gap 17 is adjusted to be uniform by the centering bolt 16. The driving groove 13 and the driving key 14 interact with each other to drive the rotor 20 of the passive device to rotate. At this time, the pointer 5 corresponds to the azimuth angle of the steering wheel 4. Based on this, the personnel will record the swing direction and swing value of the shaft system at this moment, thereby abandoning the original "track hauler" type manual drive process, optimizing the working environment, improving working conditions, and realizing dignified and decent work for personnel.

[0033] This designed structure provides direction for shaft system swing adjustment, shifting from a single scalar adjustment to simultaneous adjustment of both the direction and magnitude of the swing. This provides a basis for avoiding resonance and other hazards caused by overlapping swings. This structural solution thoroughly implements the principle of couples, and the hollow frame bracket 18 relieves tangential stress.
