Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna mount, a processing method, and an antenna system. Background Technology

[0002] In the field of high-end precision equipment, XY turntables with counterweight-free architectures have become one of the mainstream technologies for achieving high dynamic and high-precision pointing and tracking of heavy-duty antennas. For applications where the antenna reflector weighs over 700 kg, existing solutions often employ a combination of a motor-gear drive system and tapered bearing support. This solution uses symmetrically arranged servo motors to drive customized sector gears; simultaneously, tapered bearings, through rigid preload technology, provide extremely high axial and radial stiffness to withstand complex alternating overturning moments and dynamic loads. In traditional XY turntables, the worm gear transmission is inefficient and prone to overheating, severely limiting the system's maximum speed and acceleration, resulting in insufficient rapid response; furthermore, the two axes are always under eccentric load, requiring significant drive power to overcome the continuous unbalanced torque, leading to low energy efficiency.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0025] like Figures 1 to 9 As shown, a first aspect of the embodiments of this application provides an antenna mount comprising: a base 110, an X-axis module 120, a Y-axis module 130, and a bracket 140; wherein, the X-axis module 120 is connected to the bracket 140, the Y-axis module 130 is connected to the X-axis module 120, the bracket 140 is connected to the Y-axis module 130, the bracket 140 swings relative to the base 110 in the Y-axis direction based on the Y-axis module 130, and the Y-axis module 130 and the bracket 140 swing relative to the base 110 in the X-axis direction based on the X-axis module 120. The device is designed for oscillation. The X-axis module 120 includes a first gear 121 and an angular contact bearing 122, with the first gear 121 connected to the base 110 via the angular contact bearing 122. The Y-axis module 130 includes a second gear 131, a second drive component 132, and a planetary reducer 133. The second gear 131 is connected to the Y-axis module 130, the output end of the second drive component 132 is connected to the planetary reducer 133, the planetary reducer 133 is connected to the second gear 131, and the second drive component 132 is fixedly connected to the bracket 140.

[0026] The antenna mount provided in this embodiment includes a base 110, an X-axis module 120, a Y-axis module 130, and a bracket 140. When the antenna mount is in operation, the bracket 140 is used to fix the antenna body 210, and the base 110 provides stable support for the entire assembly. In the X-axis module, the first gear 121 is reliably connected to the base 110 via an angular contact bearing 122, ensuring the stability of rotation in the X-axis direction. The second drive component 132 of the Y-axis module is fixed to the bracket 140. After startup, the second drive component 132 outputs power, which is transmitted to the second gear 131 via a planetary reducer 133, driving the bracket 140 to move relative to the Y-axis module, thereby achieving precise swinging of the bracket 140 and the antenna body 210 relative to the base 110 in the Y-axis direction. Simultaneously, the X-axis module drives the first gear 121 to rotate via its own transmission mechanism. Since the Y-axis module is connected to the X-axis module, the rotation of the first gear 121 will cause the Y-axis module and the support 140 as a whole to swing relative to the base 110 around the X-axis. Through the coordinated operation of the X-axis module and the Y-axis module, with the support of the angular contact bearing 122, the power transmission of the planetary reducer 133, and the meshing transmission of the gears, the support 140 achieves compound movement in the X-axis and Y-axis directions, meeting the azimuth adjustment requirements of the antenna tracking target.

[0027] The antenna mount provided in this embodiment uses an angular contact bearing 122 to connect the first gear 121 to the base 110 in the X-axis module. The angular contact bearing 122 has good radial and axial load-bearing capacity, effectively improving the rigidity and accuracy of X-axis rotation and reducing offset errors during movement. In the Y-axis module, the planetary reducer 133 cooperates with the second drive component 132 and the second gear 131. The planetary reducer 133 has the advantages of a large transmission ratio range and high output torque, which can efficiently convert the power of the second drive component 132 into precise driving force, ensuring the smoothness and controllability of the Y-axis swing. The reasonable connection between the bracket 140 and each module, as well as the dual-axis coordinated motion design, realizes the flexible adjustment of the antenna in two-dimensional space, meeting the azimuth adjustment requirements of high dynamic tracking scenarios. The overall structure, through the optimized combination of components such as gears, bearings, and reducers, improves the load-bearing capacity and operational reliability of the antenna mount while ensuring motion accuracy, providing a solid foundation for the stable operation of the antenna.

[0028] like Figures 1 to 9As shown, in one feasible embodiment, the X-axis module 120 further includes: a first sheath 123, which is sleeved on the outside of the first gear 121; a first code disk 124, which is disposed on the base 110 and used to detect the rotation angle of the first gear 121 relative to the base 110; a first drive member and a right-angle reducer 126, the output end of the right-angle reducer 126 being connected to the first gear 121, and the first drive member being connected to the right-angle reducer 126, for driving the first gear 121 to rotate relative to the base 110.

[0029] In this technical solution, the X-axis module 120 may further include a first sheath 123, a first encoder 124, a first drive component, and a right-angle reducer 126. The first sheath 123 is fitted over the outside of the first gear 121, forming an effective protective barrier that prevents dust, moisture, and other foreign objects from entering the gear meshing area, reducing wear and corrosion, extending gear life, and preventing external environmental interference with transmission accuracy, thus ensuring transmission stability. The first encoder 124 is mounted on the base 110 and detects the rotation angle of the first gear 121, providing real-time feedback on the X-axis rotation position information, providing data support for precise control, significantly improving the positioning accuracy of X-axis oscillation, and ensuring the azimuth accuracy when the antenna tracks the target. The combination of the first drive component and the right-angle reducer 126, with the right-angle reducer 126 possessing efficient power transmission characteristics, can smoothly and accurately transmit the power of the first drive component to the first gear 121, driving it to rotate stably. This not only enhances the power output stability of the X-axis drive but also achieves precise control of the X-axis rotation speed through the speed regulation function of the reducer. The new components work synergistically with the existing structure, not only enhancing the protection and control precision of the X-axis module, but also improving power transmission efficiency and operational reliability, providing a stronger guarantee for the high-dynamic, high-precision operation of the entire antenna mount.

[0030] like Figures 1 to 9 As shown, in one feasible embodiment, the X-axis module 120 further includes: a first limiting component 127, which is used to limit the rotation angle of the first gear 121 relative to the base 110. The first limiting component 127 includes: a first limiting member 1271, which is disposed on the first gear 121; a second limiting member 1272, which is disposed on the base 110. When the first gear 121 rotates to its limit position, the first limiting member 1271 contacts the second limiting member 1272 to form a mechanical limit; and a first limit switch 1273, which is disposed on the first gear 121 to form an electronic limit.

[0031] In this technical solution, the X-axis module 120 may further include a first limiting component 127, which may include a first limiting member 1271, a second limiting member 1272, and a first limit switch 1273. The first limiting member 1271 and the second limiting member 1272 are respectively fixed to the first gear 121 and the base 110. When the first gear 121 rotates to its limit position, the two directly contact each other to form a rigid block, which can quickly cut off the tendency of excessive rotation and effectively avoid mechanical failures such as gear meshing damage and bearing overload caused by X-axis overtravel, thus greatly improving the structural operation safety. In terms of electronic limit, the first limit switch 1273 is installed on the first gear 121 and can monitor the rotation position in real time. When it approaches the limit travel, it can trigger the electronic protection mechanism in advance to achieve non-contact precise limit. This not only further avoids the impact damage that may be caused by mechanical hard contact, but also works with the control system to achieve smooth stopping and reverse adjustment, ensuring the smoothness of the movement process. The dual limit mechanism works synergistically, establishing a safety baseline through mechanical limits and improving limit accuracy and operational stability through electronic limits. This effectively constrains the rotation range of the first gear 121, preventing damage to the module and the entire antenna mount caused by overtravel, providing dual protection for precise and safe operation of the X-axis, and further enhancing the reliability of the antenna mount.

[0032] like Figures 1 to 9 As shown, in one feasible embodiment, the Y-axis module 130 further includes: a second sheath 134, which is sleeved on the outside of the second gear 131; and a second code disk 135, which is disposed on the bracket 140 and used to detect the rotation angle of the bracket 140 relative to the second gear 131.

[0033] In this technical solution, the Y-axis module 130 may include a second sheath 134 and a second code disk 135. The second sheath 134 is fitted over the outside of the second gear 131, effectively blocking dust, moisture, and other foreign objects, preventing wear and corrosion of the gear meshing surface, extending the service life of the transmission components, and ensuring transmission stability. The second code disk 135 is mounted on the bracket 140 and can accurately detect the rotation angle of the bracket 140 relative to the second gear 131 in real time, providing real-time position feedback for the Y-axis oscillation. This, combined with the control system, enables precise speed adjustment and positioning, significantly improving the Y-axis motion accuracy. Together with the existing structure of the Y-axis module, both enhance environmental adaptability and ensure the accuracy of oscillation control, providing strong support for the high-dynamic, high-precision operation of the antenna mount's dual-axis coordination.

[0034] like Figures 5 to 7As shown, in one feasible embodiment, the Y-axis module 130 further includes: a second limiting component 136, which is used to limit the rotation angle of the bracket 140 relative to the second gear 131. The second limiting component 136 includes: a third limiting member 1361, which is disposed on the bracket 140; a fourth limiting member 1362, which is disposed on the second gear 131. When the bracket 140 rotates to its limit position, the third limiting member 1361 contacts the fourth limiting member 1362 to form a mechanical limit; and a second limit switch 1363, which is disposed on the bracket 140 to form an electrically controlled limit.

[0035] In this technical solution, the Y-axis module 130 may further include a second limiting component 136, which may include a third limiting element 1361, a fourth limiting element 1362, and a second limit switch 1363. The third limiting element 1361 and the fourth limiting element 1362 are respectively mounted on the bracket 140 and the second gear 131. When the bracket 140 rotates to its limit position, the two elements rigidly contact each other to form an effective blockage, which can quickly curb excessive rotation and avoid mechanical damage such as gear meshing failure and bracket 140 deformation caused by Y-axis overtravel, thus strengthening the structural safety defense. In terms of electrical control limiting, the second limit switch 1363 is installed on the bracket 140 and can monitor the rotation stroke in real time. When approaching the limit position, it can trigger the electrical control protection in advance to achieve non-contact precise limiting. This not only avoids the impact and vibration caused by mechanical hard contact on the transmission accuracy, but also works with the control system to achieve smooth stopping and reverse adjustment, ensuring smooth movement. The dual limiting mechanism works in tandem, using mechanical limits to safeguard the bottom line of safety while using electronic limits to improve limiting accuracy and operational stability. It precisely constrains the rotation range of the bracket 140 relative to the second gear 131, effectively protecting the Y-axis module components and the overall structure. This provides dual protection for the high-precision, safe, and reliable operation of the Y-axis, further enhancing the overall reliability and service life of the antenna mount.

[0036] like Figures 1 to 9As shown, in one feasible implementation, the first gear 121 and the second gear 131 are fixedly connected, and the rotation center of the first gear 121 is orthogonal to the rotation center of the second gear 131. This configuration ensures synchronized transmission between the two gears, avoiding power transmission losses and deviations caused by relative displacement, improving the consistency of the X-axis and Y-axis movements, and providing a stable structural foundation for dual-axis composite motion. The orthogonal arrangement of the rotation centers ensures a precise perpendicular relationship between the X-axis and Y-axis motion trajectories, enabling omnidirectional coverage in two-dimensional space, perfectly adapting to the azimuth adjustment requirements when the antenna tracks a target, and effectively expanding the antenna's working coverage range. This structural design fundamentally guarantees the verticality and coordination of the dual-axis motion, reduces pointing errors caused by axis deviations, and significantly improves the positioning accuracy and tracking accuracy of the antenna mount. Meanwhile, the combination of orthogonal structure and fixed connection optimizes the force transmission path, reduces local stress concentration, and enhances the rigidity and stability of the overall structure. This enables the antenna mount to maintain reliable performance in high-dynamic operating scenarios, providing key technical support for applications such as high-precision satellite tracking.

[0037] In one feasible embodiment, the antenna mount further includes a brake device disposed at the output end of the second drive member 132 and at the output end of the first drive member of the X-axis module 120.

[0038] In this technical solution, the antenna mount may also include a brake device. This brake device can lock the second and first driving components 132 when they are stopped. It can also be quickly activated when the driving components stop or are powered off, mechanically locking the drive shaft to prevent accidental rotation of the X and Y axes due to eccentric loads or external forces. This ensures the antenna's positional stability during static operation or maintenance, avoiding tracking deviations or safety hazards caused by displacement. Simultaneously, during dynamic operation, the brake device, in conjunction with limit components and the control system, can achieve an emergency braking function, quickly cutting off power transmission and locking the shaft system in case of sudden failures or overtravel risks, reducing impact damage. Its bidirectional configuration covers the dual-axis drive system, further enhancing the overall structural safety redundancy and improving the antenna mount's operational reliability under high load and high dynamic scenarios, providing crucial safety assurance for the stable implementation of high-precision tracking tasks.

[0039] In some examples, during antenna mount use: the upper end of the bracket 140 of the Y-axis module 130 supports the antenna, and the lower end is arranged along the Y-axis via angular bearings. The second gear 131 of the Y-axis is fixed by screws and keyways. The second drive component 132 and planetary reducer 133 of the Y-axis module 130 are mounted on the upper end of the bracket 140. When the antenna moves along the Y-axis, the second gear 131 remains fixed to the Y-axis. The second drive component 132 drives the bracket 140 and the antenna to roll around the circumference of the second gear 131, thereby driving the antenna to rotate along the Y-axis.

[0040] In some examples, during antenna mount use: the upper plane of the first gear 121 of the X-axis module 120 is connected to the lower plane of the second gear 131 of the Y-axis module 130. First, the two axes are aligned perpendicularly, then positioned and tightened using pins. The first drive unit and right-angle reducer 126 of the X-axis module 120 are mounted at the lower end of the base 110. When the antenna moves along the X-axis, the first drive unit and the bases 110 on both sides remain fixed. The first drive unit rotates, thereby driving the Y-axis module 130 and the antenna to rotate along the X-axis. The first limiting component 127 and the second limiting component 136 are used to ensure that the antenna operates within a safe range in the X-axis and Y-axis directions; the working range of the X-axis and Y-axis of this device is ±90°. The antenna mount does not have counterweights in either the X-axis or Y-axis directions; the motor can prevent eccentricity during antenna operation through a brake function.

[0041] In some examples, railings and maintenance platforms are designed on the antenna mount to facilitate equipment maintenance, allowing maintenance personnel conveniently and safely access various work locations. Each axis system is equipped with lifting interfaces for easy assembly. During maintenance, personnel can climb along the outside of the antenna tower base to the bottom platform of the antenna mount, and then climb along the antenna to reach various positions on the antenna to perform maintenance on mechanical limit switches, locking devices, pitch drives, and other components. The climbing device adopts a ring-shaped design, ensuring that maintenance personnel can reach any position on the antenna mount. The antenna mount provided in this application embodiment has a movement range of -90° to 90° for both the X and Y axes. Specifically, for mechanical limiting, a 3° limit margin is reserved on both sides, resulting in actual mechanical limiting movement ranges of -93° to 93° for both the X and Y axes. The structural design of the limiting blocks ensures that the movement range of each axis meets the design requirements. The actual electrical limiting movement ranges are -87° to 87° for both the X and Y axes.

[0042] like Figure 11 As shown, a method for processing an antenna mount is provided according to a second aspect of the embodiments of this application, for fabricating an antenna mount as described in any of the above technical solutions. The processing method includes: Step 201: Prepare the first gear and perform preliminary machining on the rotation center of the first gear; Step 202: Prepare the second gear and perform preliminary machining on the rotation center of the second gear; Step 203: Assemble the first gear and the second gear, and perform precision machining on the rotation center of the first gear and the rotation center of the second gear.

[0043] Since the antenna mount processing method provided in this application embodiment is used to prepare antenna mounts as described in any of the above technical solutions, the preparation method has all the beneficial effects of the antenna mount processing method of the above technical solutions, and will not be elaborated here.

[0044] The antenna mount manufacturing method provided in this application involves first fabricating the first gear and the second gear separately, and then preliminarily machining the rotation center. This allows for independent control of the basic machining accuracy of each gear, avoiding increased machining difficulty due to mutual interference after assembly. The joint finishing process after assembly directly corrects the coaxiality and positional deviations generated during the assembly of the two gears, ensuring that the orthogonality accuracy of the rotation centers of the first and second gears meets design requirements. This fundamentally reduces pointing errors caused by shaft system deviations, laying the foundation for high-precision dual-axis coordinated motion. Simultaneously, this method eliminates the need for complex subsequent correction processes, simplifying the manufacturing process, reducing the risk of rework due to insufficient precision, and improving production efficiency. The joint finishing process also optimizes the connection stability of the two gears, making power transmission smoother, reducing transmission losses, and further enhancing the operational reliability and service life of the antenna mount, providing solid manufacturing process support for its high-dynamic and high-precision application requirements.

[0045] It is understandable that the diameter of the pre-machined shaft hole is smaller than the designed diameter of the shaft hole.

[0046] In some examples, the structures of the first and second gears can be the same. The gear meshing with the first gear in a right-angle reducer can also be the same as the gear meshing with the second gear in a planetary reducer. To verify the reliability of the antenna mount, the following verification process refers to the first and second gears as the large gear, and the gear meshing with the large gear in the reducer as the small gear. Taking a 4.5m antenna, a receiving frequency of 20.2GHz, and a half-power beam angle of 0.23° as an example: The antenna's pointing accuracy is better than 1. 7. Half-power beam angle, C=0.033° The large gear is the final output stage, so the hypotenuse is the pitch circle of the large gear, b = 405 mm.

[0047] mm

[0048] if and If they are equal, then The cutting depth and root clearance of the pinion and gear are equal, and the overlap is the greatest.

[0049] Where C is the beam angle, , For side clearance, This represents the maximum permissible tooth thickness tolerance for large gears. Maximum allowable tooth thickness tolerance for pinion .

[0050] Known , For tooth thickness deviation

[0080] The antenna system provided in this application includes the antenna mount of any of the above-described technical solutions. Therefore, the antenna system has all the beneficial effects of the antenna mount of the above-described technical solutions, which will not be elaborated here.

[0081] In one feasible implementation, the antenna system further includes: a radome 220 that covers the antenna mount and the antenna body 210; and a monitoring system connected to the radome 220 for detecting the operational status of the antenna body 210. In some examples, the monitoring system may include a smoke detector 231, a video monitoring device 232, and a fault alarm device 233.

[0082] In this technical solution, the protective cover 220 provides all-around protection for the antenna mount and antenna body 210, effectively blocking external dust, rain, snow, foreign objects, and other corrosive elements, reducing environmental damage to precision components, and extending the system's service life. The monitoring system integrates a smoke detector 231, video surveillance, fault alarms, and other devices, enabling real-time monitoring of the antenna's operational status, timely detection of fire hazards, equipment anomalies or malfunctions, rapid alarm issuance, and visual monitoring support. This facilitates timely troubleshooting and reduces operational risks.

[0083] In some examples, the antenna system may also include a lightning protection device 234 mounted on the housing 220, an aviation warning device 235, and a lighting device 236 mounted inside the housing 220. This configuration, with the addition of the lightning protection device 234, aviation warning device 235, and lighting device 236, further enhances the safety protection and ease of maintenance of the antenna system. The lightning protection device 234 can withstand lightning strikes, preventing damage to delicate electronic components; the aviation warning device 235 can alert aerial targets, reducing the risk of collision; and the lighting device 236 provides sufficient light for equipment maintenance within the housing 220, improving maintenance efficiency. These three elements complement the protection system from three aspects: environmental protection, external warning, and internal maintenance, making the antenna system safer to operate and easier to maintain in complex outdoor environments.

[0084] In some examples, the antenna system may also include a temperature control device 237, which includes an air conditioner. The indoor unit of the air conditioner is housed inside the protective cover 220, while the outdoor unit is located outside the cover. This design, with the indoor unit inside the cover and the outdoor unit outside, efficiently regulates the temperature inside the cover, preventing performance degradation or malfunction of precision electronic components and transmission mechanisms due to high or low temperatures or drastic changes in temperature and humidity. A stable temperature environment ensures the transmission accuracy of the antenna mount, the operational stability of the motor and electronic control system, and protects the signal reception performance of the antenna itself from the influence of ambient temperature and humidity. This design balances cooling and heating needs, adapts to different climatic conditions, significantly improves the antenna system's adaptability and continuous operational reliability in extreme environments, and provides a stable temperature field guarantee for high-precision, long-term satellite tracking and other operations.
