Description

Technical Field

[0001] The invention relates to the technical field of vertical transmission, and more specifically to a vertical transmission device of an electric actuator. Background Art

[0002] The transmission system of the electric actuator is usually transmitted through a gear box, and there is also a planar connecting rod form. This planar connecting rod form has poor reliability and low efficiency, the transmission speed ratio is not changeable and there is no overload protection. The transmission pairs are rigidly connected, and the deformation caused by temperature changes cannot be eliminated. It has the defects of large size, poor appearance and large workload of on-site installation.

[0003] The Chinese invention patent with the publication number CN116085437A discloses a vertical transmission device for an electric actuator. It includes gears, screws, nuts, pins, set screws, hemispheres, bearings, rudder shafts, fork teeth, sensor gears, and angular position sensor gears; the bottom end face of the screw is in contact with the hemisphere; the device is connected between the fork teeth at both ends of the rudder shaft, the sensor gear and the rudder shaft by radial pins, and rotates coaxially with the rudder shaft. The sensor gear and the angular position sensor gear are driven by gear meshing, and finally the angular position sensor feeds back the real-time deflection angle of the rudder surface. The device solves the vertical transmission problem of the dual-channel servo in a limited and narrow space under a high launch overload environment for electric actuators for 57mm caliber bullets, realizes transmission in a limited and narrow space, and uses the deformation of the hemisphere itself to absorb the instantaneous high overload impact generated during launch.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The vertical transmission device of an electric actuator involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0027] Reference Figure 1-3The present invention provides a vertical transmission device of an electric actuator, including a reduction housing 1, the reduction housing 1 including 101, the top of 101 is fixedly connected with an output end housing 2, the interior of 101 is respectively fixedly connected with a first support plate 102, a second support plate 103, a third support plate 104, a fourth support plate 105 and a fifth bracket 106 from bottom to top, the bottom of 101 is installed with an input shaft 3, the top of the first support plate 102 is located on the side of the input shaft 3 and is installed with a first detection component 5, the interior of the second support plate 103 is provided with a lubrication box 107, the outer side of the lubrication box 107 is connected with an oil delivery hole 109, the first support plate 102 and the fourth support plate 105 are located at the same position. A transmission shaft 4 is installed on the side of the input shaft 3, and gears are fixedly connected at both ends of the transmission shaft 4. A threaded rod is fixedly connected to the top of the transmission shaft 4 located at the top of the top gear. The threaded rod and the threaded transmission rod 8 form a worm mechanism. The threaded transmission rod 8 and the output shaft 9 form a worm mechanism. The bottom and top gears are meshed and connected with the input shaft 3 and the second detection component 7 respectively. The bottom of the second support plate 103 is located at the first detection component 5 and an optical detection plate 6 is installed. The light emitted by the first detection component 5 irradiates the optical detection plate 6. A stabilizing sleeve 108 is fixedly connected to the bottom of the interior of 101, and the bottom of the transmission shaft 4 is installed inside the stabilizing sleeve 108. In this embodiment, it should be specifically explained that rolling bearings 12 are installed on the outer sides of the input shaft 3 and the output shaft 9 , and an input end housing 13 is installed on the bottom of the reduction housing 1 .

[0028] The main difference between this embodiment and the prior art is that in this embodiment, the pressure of the actuator under high load is used to achieve automatic fixation, thereby increasing the fixing effect. At the same time, the centrifugal force of high-speed rotation is combined with the pressure under high load to achieve automatic release of lubricating oil, reduce wear between teeth, and enhance stability. Optical amplification is used to achieve vibration detection of the transmission structure under high load conditions, specifically in the input shaft 3, the first detection component 5, and the stabilizing component 11; The above structure is the main structure of this embodiment, which solves the problem of transmission looseness caused by high load. The optical detection plate 6 is an existing structure, and the specific structure and connection method of the optical detection plate 6 are not described in detail in this embodiment.

[0029] Reference Figure 4The first detection component 5 includes a detection arc plate 501 and a detection bracket 503. The detection arc plate 501 is sleeved inside the detection bracket 503. A launch frame 504 is hinged on the top of the detection bracket 503. The bottom of the launch frame 504 is connected to the detection arc plate 501 through a connecting diagonal rod 502. A spring is sleeved on the outer side of the detection arc plate 501. Under high load, as the stable central axis 304 vibrates, the detection arc plate 501 pushes the connecting diagonal rod 502 to move sideways. At this time, the inclination angle of the launch frame 504 changes, and the position of the light irradiated by the launch frame 504 at the optical detection plate 6 changes. At this time, the vibration condition under high load is detected by amplifying the vibration and converting it into optical displacement.

[0030] In this embodiment, it is necessary to specifically explain that: the detection arc plate 501 is sleeved inside the detection bracket 503, a spring is sleeved on the outside of the detection arc plate 501, and the detection bracket 503 is fixedly mounted on the first support plate 102. When vibration occurs, the spring uses elastic force to reduce the impact of the vibration on the device. At the same time, the movement distance of the detection arc plate 501 caused by the vibration is converted into an angle value change of the launch frame 504 through the connecting inclined rod 502, and then the distance is amplified through the optical detection plate 6 installed at a long distance, so that the detection process is more sensitive. It should be noted that the high-load operating environment will not cause obvious longitudinal changes in the first detection component 5. Therefore, the detection process of the first detection component 5 is independent of the load, so that the detection structure has higher stability.

[0031] Reference Figure 5 The stabilizing assembly 11 is composed of a displacement sleeve 1101 and a stabilizing arc plate 1103. A sliding rod 1104 is fixedly connected to the side of the stabilizing arc plate 1103. The sliding rod 1104 is installed in the sliding groove on the side of the displacement groove 203. A threaded hole is provided on the inner side of the displacement sleeve 1101. The threaded hole allows the bolt to drive the displacement sleeve 1101 to move downward when the bolt is tightened. As the displacement sleeve 1101 moves, the displacement sleeve 1101 drives the sliding rod 1104 and the stabilizing arc plate 1103 to move inward, so that the stabilizing arc plate 1103 applies a fixed pressure to the outer side of the fixed frame 10.

[0032] In this embodiment, it is necessary to specifically explain that: the displacement groove 203 is located at the bottom of the displacement sleeve 1101 and is installed with a third spring 1102. The third spring 1102 makes the displacement sleeve 1101 always have a tendency to move upward. In the fixed installation stage, the tightening force of the bolt overcomes the spring pressure to increase the clamping force of the stabilizing arc plate 1103 on the fixing frame 10. After the bolt is removed, the displacement sleeve 1101 moves upward under the action of the third spring 1102, so that the stabilizing arc plate 1103 moves outward and disengages from the inside of the transmission groove 202, so that it does not affect the normal disassembly of the fixing frame 10.

[0033] Reference Figure 6The input shaft 3 includes an input end shaft 301 and a stabilizing middle shaft 304. The outer side of the input end shaft 301 is sleeved with a rolling bearing 12. The outer side of the stabilizing middle shaft 304 is fixedly connected with an oil delivery plate 302 and a first gear 303. The first gear 303 is installed on the outer side of the stabilizing middle shaft 304 through a key connection. The oil delivery plate 302 is welded to the outer side of the stabilizing middle shaft 304. The bottom of the oil delivery plate 302 is located at the edge of the first gear 303 and is provided with an oil delivery groove 305. The inner side of the oil delivery groove 305 is provided with an oil controller 306. The oil controller 306 The first spring 307 is sleeved on the outer side. When the device needs lubrication, the rotation speed of the input end shaft 301 is increased. The rotation of the input end shaft 301 causes the oil controller 306 inside the oil delivery plate 302 to move outward under the action of centrifugal force. The two ends of the oil controller 306 are respectively connected to the oil delivery groove 305 and the oil delivery pipe 308. The lubricating oil enters the inside of the oil delivery groove 305 from the oil delivery pipe 308 under the action of centrifugal force, so that the lubricating oil enters the gap between the teeth of the first gear 303 and the transmission shaft 4, thereby realizing lubrication of the first gear 303.

[0034] In this embodiment, it should be specifically explained that: in a high-load environment, the lubricating oil is subjected to a downward force, which combined with the centrifugal force makes it easier for the oil to enter the interior of the pipeline to achieve lubrication. At the same time, in a low-speed environment, when the oil controller 306 does not move outward, the oil pipe 308 is separated from the pipeline of the oil controller 306, and the oil cannot be connected to the oil tank 305 and cannot be input into the oil tank 305.

[0035] Reference Figure 3 and 7 The output end shell 2 includes a shell body 201 and a fixed circular plate 204. A transmission groove 202 is opened inside the shell body 201, and a displacement groove 203 is opened on the outer side of the transmission groove 202. The bottom of the shell body 201 is fixedly connected with the fixed circular plate 204 by bolts, and the bolts are installed inside the bolt holes 205. When the output end shell 2 and the output shaft 9 are installed, the output shaft 9, the rolling bearing 12, and the fixing frame 10 are first placed in the transmission groove 202 in sequence, and then the shell body 201 is placed on the fixed circular plate 204, and then the bolt is placed inside the displacement groove 203 through the displacement groove 203. As the bolts are tightened, the bolts drive the displacement sleeve 1101 to move downward. As the displacement sleeve 1101 moves, the displacement sleeve 1101 drives the sliding rod 1104 and the stable arc plate 1103 to move inward, so that the stable arc plate 1103 applies a fixed pressure to the outer side of the fixing frame 10. As the bolts are fixed in four directions, the fixing frame 10 plays a role in positioning and supporting the output shaft 9.

[0036] In this embodiment, it is necessary to specifically explain that: when encountering a high load condition, the device as a whole moves at high speed and the top pressure increases. At this time, the stabilizing assembly 11 and the bolts have a tendency to move downward, and as the displacement sleeve 1101 and the bolts descend, the clamping force of the stabilizing arc plate 1103 on the fixing frame 10 increases, thereby overcoming the problem of loosening of the device caused by the high load.

[0037] Reference Figure 8 The second detection component 7 includes a rotating main shaft 701, the external key of the rotating main shaft 701 is connected to the second gear 702, the bottom of the rotating main shaft 701 is fixedly connected to a rotating frame 703, a detection groove is provided at the bottom of the rotating frame 703, and detection scale grooves are provided on both sides of the detection groove. A displacement sensor 704 is installed inside the detection groove, and a second spring 705 is sleeved on the outer side of the displacement sensor 704. When the second gear 702 rotates at a high speed, the displacement sensor 704 moves outward under the action of centrifugal force, and the magnitude of the centrifugal force is proportional to the moving distance. The rotation speed of the second detection component 7 is detected by detecting the moving distance of the displacement sensor 704, and the rotation speed data of the input shaft 3 is collected.

[0038] In this embodiment, it should be specifically explained that: when moving, the second gear 702 rotates driven by the input shaft 3 and the transmission shaft 4. At this time, the displacement sensor 704 moves outward under the action of centrifugal force. The centrifugal force overcomes the pressure of the second spring 705, so that the rotation speed is proportional to the moving distance. The rotation speed is detected by the detection scale groove opened on the side of the displacement sensor 704.

[0039] Working principle of the present invention: The main problem solved by this embodiment is: to use the pressure of the actuator under high load to achieve automatic fixation, increase the fixing effect, and reduce the problem of transmission looseness caused by high load. At the same time, the centrifugal force of high-speed rotation combined with the pressure under high load conditions is used to achieve automatic release of lubricating oil, reduce wear between teeth, and enhance stability. At the same time, optical amplification is used to realize vibration detection of the transmission structure under high load environment.

[0040] The specific steps are as follows: During the process of installing the output end housing 2 on the reduction housing 1, the output shaft 9, the rolling bearing 12, and the fixing frame 10 are first placed in the transmission groove 202 in sequence, and then the housing body 201 is placed on the fixing circular plate 204, and then the bolt is placed in the displacement groove 203 through the displacement groove 203. As the bolt is tightened, the bolt drives the displacement sleeve 1101 to move downward, and as the displacement sleeve 1101 moves, the displacement sleeve 1101 drives the sliding rod 1104 and the stabilizing arc plate 1103 to move inward, so that the stabilizing arc plate 1103 is 103 applies a fixing pressure to the outside of the fixing frame 10. With the bolts fixed in four directions, the fixing frame 10 plays a role of positioning and supporting the output shaft 9. After the outside of the fixing circular plate 204 is fixed, the output end shell 2 is installed. When encountering a high load, the device as a whole moves at a high speed, and the top pressure increases. At this time, the stabilizing component 11 and the bolts have a downward movement trend. As the displacement sleeve 1101 and the bolts descend, the clamping force of the stabilizing arc plate 1103 on the fixing frame 10 increases, overcoming the problem of loosening of the device caused by high load. During normal transmission, as the input end shaft 301 rotates, the first gear 303 drives the gears at both ends of the transmission shaft 4 to rotate, and the gears are decelerated twice by the screw mechanism of the threaded transmission rod 8 and transmitted to the top through the output shaft 9. When the device needs lubrication, the rotation speed of the input end shaft 301 is increased. The rotation of the input end shaft 301 causes the oil controller 306 inside the oil delivery plate 302 to move outward under the action of centrifugal force. The two ends of the oil controller 306 are respectively connected to the oil delivery groove 305 and the oil delivery pipe 308. The lubricating oil enters the inside of the oil delivery groove 305 from the oil delivery pipe 308 under the action of centrifugal force. By using high load, the lubricating oil enters the gap between the teeth of the first gear 303 and the transmission shaft 4, thereby achieving lubrication of the first gear 303. At the same time, the gear at the other end of the transmission shaft 4 is meshed with the second gear 702. When in motion, the second gear 702 rotates driven by the input shaft 3 and the transmission shaft 4. At this time, the displacement sensor 704 moves outward under the action of centrifugal force. The centrifugal force overcomes the pressure of the second spring 705, so that the rotation speed is proportional to the moving distance. The rotation speed is detected through the detection scale groove opened on the side of the displacement sensor 704. Under high load, the stability of the input end shaft 301 is reduced. As the input end shaft 301 rotates, the top stabilizing center shaft 304 vibrates. The vibration causes the detection arc plate 501 to push the connecting diagonal rod 502 to move sideways. At this time, the inclination angle of the launch frame 504 changes, and the position of the light irradiated by the launch frame 504 on the optical detection plate 6 changes. At this time, the vibration condition under high load is detected by amplifying the vibration and converting it into optical displacement.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
