Description

Technical Field

[0001] The invention relates to the technical field of transmission structures of vertical circulation garages, and in particular to a transmission structure of a slewing bearing and a gear drive applied to a vertical circulation garage. Background Art

[0002] At present, most of the vertical circulation equipment on the market adopts fork transmission, which has problems such as high noise, large output torque demand of the reducer, large radial force of the shaft, small gap between the fork and the lower inner guide rail, and easy interference.

[0003] The toothed chains developed earlier on the market (toothed chains are generally used as lifting chains in vertical circulation garages) have smooth transmission and low noise, but the thickness of the toothed chain plates is limited to 12mm-16mm. When used in high-rise vertical circulation garages above 11 floors, the contact area between the chain plate tooth surface and the outer sleeve of the pin shaft of the pin pulley is limited, the surface contact stress is too large, the material strength of the pin shaft and the sleeve is very high, and the parts are easy to wear, resulting in restrictions on the design of higher-rise vertical circulation garages.

[0004] Patent number CN113653381A is a transmission device for a vertical circulation stereo garage. The motor directly drives the pinion to directly transmit the power to the large gear in the form of external tooth meshing to drive the entire shaft to rotate, and then the fork mechanism drives the lifting chain. Since the structure is that the large gear is coaxially fixed with the slewing bearing, the power is directly transmitted to the slewing bearing (the slewing bearing is used to drive the lifting chain to rotate, so as to drive the garage to perform vertical circulation lifting). In order to take into account the maximum output force of the motor, the small gear needs to be a small gear within the preset pitch circle range, that is, the diameter of the small gear cannot be too large, which makes the deceleration The ratio can only depend on the diameter of the large gear, and the large gear and the slewing bearing are coaxially fixed. When the motor output power is constant, when it is necessary to slow down the speed of the slewing bearing to make the lifting chain move smoothly (i.e. increase the reduction ratio), only a large gear with a larger diameter can be used, that is, increase the diameter of the large gear, which occupies most of the position and is not convenient for the structural arrangement of the power output part in the vertical garage. In addition, this kind of external tooth meshing transmission mode makes the motor have fewer optional installation positions, and it needs to be installed close to the large gear, resulting in a larger space occupation and a more dispersed overall structure. Improper adjustment of the installation position will easily lead to unsmooth or unstable power output.

[0005] Therefore, it is necessary to propose a transmission structure of a slewing bearing and a gear drive applied to a vertical circulation garage to reduce the external occupied space while also increasing the reduction ratio, so that the power output to the lifting chain is smoother. Summary of the invention

[0034] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] Please refer to Figure 1-Figure 5 The present invention proposes a transmission structure of a slewing bearing and gear drive applied to a vertical circulation garage, comprising a driving device 1, a first transmission assembly 2, a second transmission assembly 3, a connecting shaft assembly 4, and two slewing bearing assemblies 5. The driving device 1 is a large torque reduction motor. The driving device 1, the first transmission assembly 2, and the second transmission assembly 3 are all fixedly connected to the outside. The two slewing bearing assemblies 5 are both rotatably connected to a fixed frame of the vertical garage, mainly fixedly connected to the fixed frame of the vertical garage. The rotating shaft of the driving device 1 forms a transmission connection with the first transmission assembly 2, which can be direct gear meshing or through a transmission structure such as a transmission belt or chain. The first transmission assembly 2 and the second transmission assembly 3 respectively establish a synchronous transmission connection through the connecting shaft assembly 4. The two slewing bearing assemblies 5 correspond to the first transmission assembly 2 and the second transmission assembly 3 one by one, and the two slewing bearing assemblies 5 form a transmission connection in the form of internal tooth meshing on the first transmission assembly 2 and the second transmission assembly 3 respectively.

[0037] In this embodiment, the driving device 1 forms a transmission connection with the first transmission component 2, and the first transmission component 2 and the second transmission component 3 respectively establish a synchronous transmission connection through the connecting shaft component 4, so that the driving device 1 can directly transmit power to the first transmission component 2 and the second transmission component 3 at the same time, and the two slewing bearing components 5 respectively form a transmission connection in the form of internal tooth meshing on the first transmission component 2 and the second transmission component 3, so that the two slewing bearing components 5 can rotate synchronously and output power to the lifting chain smoothly, and the transmission setting of the first transmission component 2 and the second transmission component 3 and the internal tooth meshing form of the slewing bearing component 5 optimize the installation position of various structures during the transmission connection. The internal tooth meshing form makes the inner ring of the slewing bearing component 5 bear force when the rotating shaft of the driving device 1 rotates. If the slewing bearing component 5 is relative to the first transmission component 2 is in a similar hanging position, and the force point of the slewing bearing assembly 5 is above the inner ring. The force point is set as point A. The slewing bearing assembly 5 rotates clockwise for positive rotation and counterclockwise for reverse rotation. The slewing bearing assembly 5 is flat as a front view. When the driving device 1 starts and drives the slewing bearing assembly 5 to rotate forward, the slewing bearing assembly 5 will take point A as the rotation center point and swing slightly to the left. Such action will strengthen the meshing degree of the slewing bearing assembly 5 on the lifting chain, so that the gap between the lifting chain and the slewing bearing assembly 5 is reduced during startup, making the power output more stable. Similarly, when the slewing bearing assembly 5 is reversed, the meshing degree of the lifting chain will also be strengthened, thereby reducing the gap, making the power output of the slewing bearing assembly 5 more stable. While improving the reduction ratio, the overall structure is also made more compact, reducing the external occupied space.

[0038] In summary, the slewing bearing and gear-driven transmission structure used in the vertical circulation garage can effectively reduce the external occupied space, and can also increase the reduction ratio, making the power output to the lifting chain more stable.

[0039] In this embodiment, a small sprocket is provided on the rotating shaft of the driving device 1, and the rotating shaft of the driving device 1 forms a transmission connection with the first transmission component 2 through a chain 6. One end of the connecting shaft component 4 is fixedly connected to the axis of the first transmission component 2, and the other end of the connecting shaft component 4 is fixedly connected to the axis of the second transmission component 3, so that the first transmission component 2 and the second transmission component 3 respectively establish a synchronous transmission connection through the connecting shaft component 4; when the driving device 1 is running, the rotating shaft of the driving device 1 rotates to transmit power to the first transmission component 2 through the chain 6. The setting of the chain 6 enables the driving device 1 to be installed at different distances, which is convenient for adjusting the installation position of the driving device 1. When the driving device 1 rotates, the first transmission component 2 is rotated by force, and then the connecting shaft component 4 synchronizes the power to the second transmission component 3, so that the first transmission component 2 and the second transmission component 3 rotate synchronously, and together drive the two slewing bearing components 5 to rotate simultaneously.

[0040] In this embodiment, the first transmission assembly 2 includes a first bearing support assembly 21, a first transmission shaft 22, and a first transmission wheel 23. There are two first bearing support assemblies 21. The two first bearing support assemblies 21 are arranged in sequence along the direction of the first transmission shaft 22 and are fixedly connected to the outside. The first transmission shaft 22 is inserted and fixedly connected to the inner ring of the first bearing support assembly 21. The first bearing support assembly 21 includes a first bearing 211 and a first fixed seat 212. The first bearing 211 is fixedly connected to the middle area of ​​the first fixed seat 212. The first fixed seat 212 is fixedly connected to the outside by bolts. When the first transmission shaft 22 is installed, it is installed by passing through the two first bearings 211 in sequence. The two first bearings 211 provide a stable rotation support structure for the first transmission shaft 22. The first transmission shaft 22 passes through the axis of the first transmission wheel 23 and is fixedly connected to the first transmission wheel 23. The first transmission wheel 23 forms a transmission connection with the rotating shaft of the driving device 1 through the chain 6. At this time, the first transmission wheel 23 is a sprocket. If the first transmission wheel 23 forms a transmission connection with the rotating shaft of the driving device 1 through a transmission belt, then the first transmission wheel 23 is a pulley. One end of the first transmission shaft 22 is connected to the connecting shaft assembly 4. One end is fixedly connected, and the inner ring of a slewing bearing assembly 5 forms a transmission connection with the outer surface of the first transmission shaft 23; except for the first transmission wheel 23, the rest of the structure of the second transmission assembly 3 is the same as the first transmission assembly 2; when the rotating shaft of the driving device 1 rotates, the power is transmitted to the first transmission wheel 23 through the chain 6, and then the first transmission wheel 23 drives the first transmission shaft 22 to rotate, and finally the first transmission shaft 22 transmits the power to the inner ring of the slewing bearing assembly 5, so that the slewing bearing assembly 5 rotates; the transmission connection between the first transmission shaft 22 and the slewing bearing assembly 5 can be mutually connected by soft materials The transmission connection is carried out by the friction force of extrusion. For example, the outer surface of the first transmission shaft 22 and the inner ring of the slewing bearing assembly 5 are both made of rubber material. The transmission connection can also be carried out by the meshing of gears. The diameter of the first transmission wheel 23 needs to be larger than the diameter of the rotating shaft output of the driving device 1, and then the diameter of the first transmission shaft 22 is smaller than the diameter of the first transmission wheel 23. Since the slewing bearing assembly 5 is connected to the first transmission shaft 22 through the inner ring, the diameter of the slewing bearing assembly 5 is larger than that of the first transmission shaft 22, which improves the reduction ratio and makes the force finally transmitted to the slewing bearing assembly 5 more stable.

[0041] In this embodiment, a first gear 221 is provided on the first transmission shaft 22, and the slewing support assembly 5 is annular in structure and is provided with an internal gear 51, which is meshedly connected with the first gear 221; the first gear 221 is a small gear, and its diameter is slightly larger than the first transmission shaft 22, and the internal gear 51 can be fixedly connected to the inner ring of the slewing support assembly 5 by bolts, or the internal gear 51 can be directly machined on the inner ring of the slewing support assembly 5, and the meshing connection between the internal gear 51 and the first gear 221 is more secure, and no slipping occurs. When the first transmission shaft 22 rotates, the first gear 221 is driven to rotate, and then the power is transmitted to the internal gear 51, which drives the internal gear 51 to rotate, and then drives the slewing support assembly 5 to rotate as a whole.

[0042] In this embodiment, the slewing bearing assembly 5 includes a slewing ring 52 and a plurality of fork members 53. The slewing ring 52 forms a transmission connection in the form of internal tooth meshing on the first transmission assembly 2 or the second transmission assembly 3. The plurality of fork members 53 are evenly distributed circumferentially and fixedly connected to one side of the slewing ring 52. An inner ring of the slewing ring 52 is provided with an internal gear 51 for forming an internal tooth meshing transmission with the first transmission assembly 2 or the second transmission assembly 3. The internal gear 51 can be installed on the inner ring of the slewing ring 52 by bolts, or can be directly machined on the inner ring. When the slewing ring 52 is driven to rotate by the first transmission assembly 2 or the second transmission assembly 3, the plurality of fork members 53 drive the lifting chain to operate, so as to drive the garage to perform vertical circulation lifting.

[0043] In this embodiment, at least two fork openings 531 are provided on the fork member 53, and the distance between adjacent fork openings 531 on the same fork member 531 is a, and the distance between the fork opening 531 at the end of the previous fork member 53 and the fork opening 531 at the front end of the next fork member 53 is b, and a is equal to b; since the diameter of the slewing ring member 52 is large, and in order to make the garage perform a stable vertical cycle lifting, the turning range of the lifting chain will be designed to be large. If the fork member 53 is an integral ring shape, then at this time the fork member 5 3 needs to be processed into a larger diameter, which makes transportation and assembly inconvenient. In order to facilitate processing and installation, the fork member 53 is processed into multiple arc structures. After the multiple fork members 53 are installed, they will surround a circle. This circle may not be a completely connected circle, but a dotted circle, that is, there may be a gap between the multiple fork members 53, and then the lifting chain is forked through the fork opening 531. In order to ensure that the distances between the adjacent fork openings 531 are the same after the multiple fork members 53 are installed, it is necessary to design a and b to be equal.

[0044] In this embodiment, the connecting shaft assembly 4 includes two connecting shaft heads 41 and a first coupling 42. The two connecting shaft heads 41 are respectively fixedly connected to the two ends of the first connector 42, and the connecting shaft heads 41 are coaxially fixedly connected to the first transmission shaft 22; the connecting shaft head 41 is used for coaxially fixed connection with the first transmission shaft 22. Since there will be a certain position error in the alignment installation of the two slewing bearing assemblies 5, the first coupling 42 is a universal joint coupling, which can transmit power even in the case of errors.

[0045] Example 2

[0046] Please refer to Figure 5-Figure 7 The present invention proposes a transmission structure of a slewing bearing and gear drive applied to a vertical circulation garage, comprising a driving device 1, a first transmission assembly 2, a second transmission assembly 3, a connecting shaft assembly 4, and two slewing bearing assemblies 5. The driving device 1 is a large torque reduction motor. The driving device 1, the first transmission assembly 2, and the second transmission assembly 3 are all fixedly connected to the outside. The two slewing bearing assemblies 5 are both rotatably connected to a fixed frame of the vertical garage, mainly fixedly connected to the fixed frame of the vertical garage. The rotating shaft of the driving device 1 forms a transmission connection with the first transmission assembly 2, which can be direct gear meshing or through a transmission structure such as a transmission belt or chain. The first transmission assembly 2 and the second transmission assembly 3 respectively establish a synchronous transmission connection through the connecting shaft assembly 4. The two slewing bearing assemblies 5 correspond to the first transmission assembly 2 and the second transmission assembly 3 one by one, and the two slewing bearing assemblies 5 form a transmission connection in the form of internal tooth meshing on the first transmission assembly 2 and the second transmission assembly 3 respectively.

[0047] In this embodiment, the driving device 1 forms a transmission connection with the first transmission component 2, and the first transmission component 2 and the second transmission component 3 respectively establish a synchronous transmission connection through the connecting shaft component 4, so that the driving device 1 can directly transmit power to the first transmission component 2 and the second transmission component 3 at the same time, and the two slewing bearing components 5 respectively form a transmission connection in the form of internal tooth meshing on the first transmission component 2 and the second transmission component 3, so that the two slewing bearing components 5 can rotate synchronously and output power to the lifting chain smoothly, and the transmission setting of the first transmission component 2 and the second transmission component 3 and the internal tooth meshing form of the slewing bearing component 5 optimize the installation position of various structures during the transmission connection. The internal tooth meshing form makes the inner ring of the slewing bearing component 5 bear force when the rotating shaft of the driving device 1 rotates. If the slewing bearing component 5 is relative to the first transmission component 2 is in a similar hanging position, and the force point of the slewing bearing assembly 5 is above the inner ring. The force point is set as point A. The slewing bearing assembly 5 rotates clockwise for positive rotation and counterclockwise for reverse rotation. The slewing bearing assembly 5 is flat as a front view. When the driving device 1 starts and drives the slewing bearing assembly 5 to rotate forward, the slewing bearing assembly 5 will take point A as the rotation center point and swing slightly to the left. Such action will strengthen the meshing degree of the slewing bearing assembly 5 on the lifting chain, so that the gap between the lifting chain and the slewing bearing assembly 5 is reduced during startup, making the power output more stable. Similarly, when the slewing bearing assembly 5 is reversed, the meshing degree of the lifting chain will also be strengthened, thereby reducing the gap, making the power output of the slewing bearing assembly 5 more stable. While improving the reduction ratio, the overall structure is also made more compact, reducing the external occupied space.

[0048] In summary, the slewing bearing and gear-driven transmission structure used in the vertical circulation garage can effectively reduce the external occupied space, and can also increase the reduction ratio, making the power output to the lifting chain more stable.

[0049] In this embodiment, the rotating shaft of the driving device 1 is fixedly connected with the connecting shaft assembly 4 coaxially, and one end of the connecting shaft assembly 4 is connected to the first transmission assembly 2 through the chain 6, so that the rotating shaft of the driving device 1 is connected to the first transmission assembly 2 through the connecting shaft assembly 4, and the other end of the connecting shaft assembly 4 is connected to the second transmission assembly 3 through the chain 6, so that the first transmission assembly 2 and the second transmission assembly 3 are respectively connected through the connecting shaft assembly 4. Synchronous transmission connection; when the driving device 1 is running, the rotating shaft of the driving device 1 rotates to transmit power to the connecting shaft assembly 4 first, and then the connecting shaft assembly 4 is transmitted to the first transmission assembly 2 and the second transmission assembly 3 together through the chain 6, so that the installation position of the connecting shaft assembly 4 changes, which is beneficial In order to adapt to installation in different situations, the arrangement of the chain 6 enables the drive device 1 and the connecting shaft assembly 4 to be installed at different positions away from the first transmission assembly 2 and the second transmission assembly 3, which is convenient for adjusting the installation position of the drive device 1. When the drive device 1 rotates, the connecting shaft assembly 4 is rotated by force, and then the connecting shaft assembly 4 drives the first transmission assembly 2 and the second transmission assembly 3 to rotate through the chain 6, so that the first transmission assembly 2 and the second transmission assembly 3 rotate synchronously, and then drive the two slewing bearing assemblies 5 to rotate simultaneously. In this way, the torque output by the drive device 1 can be smaller, and the model of the chain 6 can be selected to be smaller, that is, there are more types of accessories to choose from, which is convenient for adjusting costs.

[0050] In this embodiment, the connecting shaft assembly 4 includes two connecting sprockets 43 and a second coupling 44. The two connecting sprockets 43 are fixedly connected to the two ends of the second connector 44 respectively. One connecting sprocket 43 forms a transmission connection with the first transmission assembly 2 through the chain 6, and the other connecting sprocket 43 forms a transmission connection with the second transmission assembly 3 through the chain 6; during power transmission, one connecting sprocket 43 transmits the power of the driving device 1 to the first transmission assembly 2, and the other connecting sprocket 43 transmits the power of the driving device 1 to the second transmission assembly 3 through the second coupling 44, so that the first transmission assembly 2 and the second transmission assembly 3 rotate synchronously. Since there will be errors in the alignment installation of the first transmission assembly 2 and the second transmission assembly 3, the second coupling 44 needs to be a universal joint coupling so that power can be transmitted even in the case of errors.

[0051] In this embodiment, the first transmission assembly 2 includes a second bearing support assembly 24, a second transmission shaft 25, and at least two second transmission wheels 26. The second transmission shaft 25 is inserted and fixedly connected to the inner ring of the second bearing support assembly 24. There are two second bearing support assemblies 24. The two second bearing support assemblies 24 are arranged in sequence along the direction of the second transmission shaft 25 and are fixedly connected to the outside. The second transmission shaft 25 is inserted and fixedly connected to the inner ring of the second bearing support assembly 24. The second bearing support assembly 24 includes a second bearing 241 and a second fixed seat 242. The second bearing 241 is fixedly connected The second fixed seat 242 is connected to the middle area of ​​the second fixed seat 242, and the second fixed seat 242 is fixedly connected to the outside by bolts. When the second transmission shaft 25 is installed, it passes through the two second bearings 241 in sequence. The two second bearings 241 provide a stable rotation support structure for the second transmission shaft 25. The second transmission shaft 25 passes through the axis of two second transmission wheels 26 arranged in parallel in sequence and is fixedly connected to the two second transmission wheels 26. The two second transmission wheels 26 are both connected to one end of the connecting shaft assembly 4 through the chain 6. The setting of the two second transmission wheels 26 requires the use of two chains. 6, and multiple second transmission wheels 26 can be set according to needs, which can improve the stability and firmness of the transmission. The inner ring of a slewing bearing assembly 5 forms a transmission connection with the outer surface of the second transmission shaft 25; the first transmission assembly 2 and the second transmission assembly 3 have the same structure, which is convenient for installation; when transmitting, the power of the connecting shaft assembly 4 is transmitted to the second transmission wheel 26, and the rotation of the second transmission wheel 26 drives the second transmission shaft 25 to rotate, thereby driving the slewing bearing assembly 5 to rotate as a whole; the transmission connection between the second transmission shaft 25 and the slewing bearing assembly 5 can be made of soft material The transmission connection is achieved by the friction force of mutual extrusion. For example, the outer surface of the second transmission shaft 25 and the inner ring of the slewing bearing assembly 5 are both made of rubber material. The transmission connection can also be achieved by the meshing of gears. The diameter of the second transmission wheel 26 needs to be larger than the diameter of the connecting sprocket 43, and then the diameter of the second transmission shaft 25 is smaller than the diameter of the second transmission wheel 26. Since the slewing bearing assembly 5 is connected to the second transmission shaft 25 through the inner ring, the diameter of the slewing bearing assembly 5 is larger than that of the second transmission shaft 25, which improves the reduction ratio and makes the force finally transmitted to the slewing bearing assembly 5 more stable.

[0052] In this embodiment, a second gear 251 is provided on the second transmission shaft 25, and the slewing support assembly 5 is annular in structure and is provided with an internal gear 51, which is meshed with the second gear 251; the second gear 251 is a small gear, and its diameter is slightly larger than that of the second transmission shaft 25. The internal gear 51 can be fixedly connected to the inner ring of the slewing support assembly 5 by bolts, or the internal gear 51 can be directly machined on the inner ring of the slewing support assembly 5. The meshing connection between the internal gear 51 and the second gear 251 is more secure, and no slipping occurs. When the second transmission shaft 25 rotates, the second gear 251 is driven to rotate, and then the power is transmitted to the internal gear 51, which drives the internal gear 51 to rotate, and then drives the slewing support assembly 5 to rotate as a whole.

[0053] In this embodiment, the slewing bearing assembly 5 includes a slewing ring 52 and a plurality of fork members 53. The slewing ring 52 forms a transmission connection in the form of internal tooth meshing on the first transmission assembly 2 or the second transmission assembly 3. The plurality of fork members 53 are evenly distributed circumferentially and fixedly connected to one side of the slewing ring 52. An inner ring of the slewing ring 52 is provided with an internal gear 51 for forming an internal tooth meshing transmission with the first transmission assembly 2 or the second transmission assembly 3. The internal gear 51 can be installed on the inner ring of the slewing ring 52 by bolts, or can be directly machined on the inner ring. When the slewing ring 52 is driven to rotate by the first transmission assembly 2 or the second transmission assembly 3, the plurality of fork members 53 drive the lifting chain to operate, so as to drive the garage to perform vertical circulation lifting.

[0054] In this embodiment, at least two fork openings 531 are provided on the fork member 53, and the distance between adjacent fork openings 531 on the same fork member 531 is a, and the distance between the fork opening 531 at the end of the previous fork member 53 and the fork opening 531 at the front end of the next fork member 53 is b, and a is equal to b; since the diameter of the slewing ring member 52 is large, and in order to make the garage perform a stable vertical cycle lifting, the turning range of the lifting chain will be designed to be large. If the fork member 53 is an integral ring shape, then at this time the fork member 5 3 needs to be processed into a larger diameter, which makes transportation and assembly inconvenient. In order to facilitate processing and installation, the fork member 53 is processed into multiple arc structures. After the multiple fork members 53 are installed, they will surround a circle. This circle may not be a completely connected circle, but a dotted circle, that is, there may be a gap between the multiple fork members 53, and then the lifting chain is forked through the fork opening 531. In order to ensure that the distances between the adjacent fork openings 531 are the same after the multiple fork members 53 are installed, it is necessary to design a and b to be equal.

[0055] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
