Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to a slewing device for operating machinery and the operating machinery. Background Art

[0002] An operating machine, such as a crawler hydraulic excavator, uses a bucket to dig materials above or below the surface of the machine and loads them into a transport vehicle or unloads them to a stockpile. The excavated materials are mainly soil, coal, silt, and pre-loosened soil and rock.

[0003] The crawler hydraulic excavator can not only walk, but also the upper platform can perform relative rotational motion relative to the lower platform, that is, the rotational motion is achieved through the gear meshing transmission between the rotary reducer and the slewing bearing. Specifically, Figure 1 As shown, the slewing reducer is fixedly connected to the mounting platform by bolts, the mounting platform is fixedly connected to the outer ring of the slewing bearing by bolts, the inner ring of the slewing bearing is fixedly connected to the lower vehicle by bolts, and balls are arranged between the inner ring and the outer ring of the slewing bearing. When the slewing reducer is controlled to work, the output gear of the slewing reducer and the inner gear ring of the slewing bearing are meshed and transmitted with each other, thereby realizing the slewing motion of the upper vehicle platform relative to the lower vehicle.

[0004] Since the slewing reducer is fixedly connected to the mounting platform by bolts, the gear center distance between the output gear of the slewing reducer and the inner gear ring of the slewing bearing is relatively fixed. After the operating machine has been running for a period of time, the meshing tooth surface between the output gear of the slewing reducer and the inner gear ring of the slewing bearing will wear, resulting in a larger meshing clearance between the output gear and the inner gear ring, causing the upper platform to shake left and right relative to the lower platform, affecting the use of the operating machine. Utility Model Content

[0005] The first aspect of the utility model provides a slewing device to solve the above-mentioned defects in the prior art. The relative position between the slewing reducer and the slewing bearing can be adjusted to reduce the meshing clearance between the output gear and the inner gear ring to meet the meshing requirements of the output gear and the inner gear ring. The slewing device can effectively avoid the upper platform from shaking left and right relative to the lower platform due to the meshing clearance between the output gear and the inner gear ring being too large, thereby affecting the use of the operating machinery.

[0006] A second aspect of the present invention provides a working machine.

[0009] A rotary reducer is arranged on the mounting platform, and the rotary reducer is provided with an output gear;

[0010] A slewing bearing is arranged on the mounting platform, the slewing bearing is provided with an inner gear ring, and the inner gear ring is meshed with the output gear;

[0011] Wherein, a guide component is provided on either the slewing reducer or the mounting platform, and an adjustment component is provided on the other of the slewing reducer and the mounting platform, and the adjustment component is used to adjust the relative position of the guide component so that the gear center distance between the output gear of the slewing reducer and the inner gear ring of the slewing bearing can be adjusted.

[0012] According to the slewing device provided by the utility model, the installation platform is provided with a first installation position and a second installation position, the slewing reducer is arranged at the first installation position, and the slewing bearing is installed at the second installation position;

[0013] The first mounting position is arranged inside the second mounting position and close to one side of the second mounting position, the guide component or the adjustment component is arranged on both sides of the first mounting position, and the symmetry axis of the guide component or the adjustment component is located on the center line of the first mounting position and the second mounting position.

[0014] According to the rotary device provided by the utility model, when the adjusting component is arranged on the mounting platform and the guiding component is arranged on the rotary reducer;

[0015] The adjusting component comprises a supporting component and an adjusting component. The supporting component is arranged on the mounting platform. An adjusting hole is opened on the supporting component. The adjusting component is threadedly connected to the adjusting hole. The end of the adjusting component abuts against the guiding component.

[0016] According to the rotary device provided by the utility model, the support member is provided with a guide groove along the length direction, and the guide component is slidably matched with the guide groove.

[0017] According to the rotary device provided by the utility model, the guide component includes a guide protrusion, the guide protrusion is guided and matched with the support member, and the end of the adjustment member abuts against the guide protrusion.

[0018] According to the rotating device provided by the utility model, the guide component also includes a limit member, which is arranged parallel to the top of the guide protrusion, the limit member is suitable for overlapping the upper surface of the support member, and the end of the adjustment member abuts against the end face of the limit member.

[0019] According to the rotary device provided by the utility model, the position of the limiting member near the two ends is provided with an extension portion, the extension portion protrudes from the upper surface of the limiting member, and the end of the adjusting member abuts against the end surface of the limiting member and the extension portion.

[0020] According to the rotary device provided by the utility model, the support member is provided with supporting lugs opposite to each other, and the adjusting hole is provided on the supporting lugs;

[0021] The distance between two supporting lugs arranged opposite to each other is greater than the length of the limiting member, so that an adjustment gap exists between the limiting member and the corresponding supporting lug.

[0022] According to the rotary device provided by the utility model, the rotary reducer includes a main body component and a mounting chassis, and the guide component or the adjustment component is arranged on the mounting chassis.

[0023] A second aspect of the utility model provides a working machine, comprising a machine body and a slewing device as described in any one of the above items, wherein the slewing device is arranged on the machine body and is used to install a slewing support.

[0024] The slewing device provided by the utility model is provided with a guide component on any one of the slewing reducer and the mounting platform, and an adjusting component is provided on the other of the slewing reducer and the mounting platform. The adjusting component is used to adjust the relative position of the guide component so that the gear center distance between the output gear of the slewing reducer and the inner gear ring of the slewing support can be adjusted, so as to adjust the meshing clearance between the inner gear ring of the slewing support and the output gear of the slewing reducer.

[0025] When the slewing device is applied to an operating machine, after the operating machine has been running for a period of time, the meshing tooth surfaces between the output gear of the slewing reducer and the inner gear ring of the slewing bearing are worn, causing the meshing clearance between the output gear and the inner gear ring to increase. The position of the guide component is adjusted by adjusting the position of the adjusting component, thereby synchronously adjusting the relative position between the slewing reducer and the slewing bearing to reduce the meshing clearance between the output gear and the inner gear ring to meet the meshing requirements of the output gear and the inner gear ring. This can effectively prevent the upper platform from shaking left and right relative to the lower platform due to excessive meshing clearance between the output gear and the inner gear ring, thereby affecting the use of the operating machine.

[0026] At the same time, when the meshing tooth surface between the output gear of the slewing reducer and the inner gear ring of the slewing bearing is worn, the corresponding parts do not need to be replaced, and the center distance between the output gear and the inner gear ring can be adjusted to continue to be used. This arrangement is conducive to after-sales maintenance of the slewing device.

[0027] Furthermore, since the relative position between the slewing reducer and the slewing bearing can be adjusted, that is, the meshing clearance between the output gear of the slewing reducer and the inner gear ring of the slewing bearing can be adjusted. Therefore, when installing the slewing device and the lower vehicle of the operating machine, a certain clearance can be reserved between the output gear of the slewing reducer and the inner gear ring of the slewing bearing to avoid interference and collision between the output gear of the slewing reducer and the inner gear ring of the slewing bearing during installation, making the installation process simpler. This can effectively solve the problem in the prior art that the center distance between the output gear of the slewing reducer and the inner gear ring of the slewing bearing is relatively fixed, and when assembling the installation platform and the lower vehicle, the installation platform needs to be rotated to a specific angle in advance so that the tooth top of the output gear of the slewing reducer is inserted into the tooth groove of the inner gear ring of the slewing bearing, resulting in a cumbersome installation process.

[0028] The operating machine provided by the utility model has all the above advantages because it includes the above-mentioned rotating device. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 2 It is a schematic diagram of the structure of the rotary device provided in the embodiment of the utility model; Figure 3 It is a schematic diagram of the structural decomposition of the rotary device provided in an embodiment of the utility model.

[0044] See also Figure 2 and Figure 3 An embodiment of the utility model provides a rotary device, which includes a mounting platform 100, a rotary reducer 200 and a rotary bearing 300. The rotary reducer 200 and the rotary bearing 300 are mounted on the mounting platform 100, and the output gear 230 of the rotary reducer 200 is meshed with the inner gear ring 310 of the rotary bearing 300.

[0045] A guide component 240 is provided on any one of the rotary reducer 200 and the mounting platform 100, and an adjustment component 130 is provided on the other of the rotary reducer 200 and the mounting platform 100. The adjustment component 130 is used to adjust the relative position of the guide component 240 so that the gear center distance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary bearing 300 can be adjusted, that is, the meshing clearance between the inner gear ring 310 of the rotary bearing 300 and the output gear 230 of the rotary reducer 200 can be adjusted.

[0046] For example, a guide component 240 is provided on the rotary reducer 200, and an adjustment component 130 is provided on the mounting platform 100. When the rotary reducer 200 is installed on the mounting platform 100, the rotary reducer 200 can be limited or guided with the mounting platform 100 through the guide component 240. The position of the guide component 240 is adjusted by the adjustment component 130, thereby adjusting the relative position between the rotary reducer 200 and the slewing support 300.

[0047] Of course, the adjusting component 130 may also be arranged on the rotary reducer 200, and the guiding component 240 may be arranged on the mounting platform 100. The specific arrangement method and working process are the same as the above-mentioned arrangement method, and will not be described in detail here.

[0048] It can be understood that the rotary device provided in the embodiment of the utility model is provided with a guide component 240 on any one of the rotary reducer 200 and the mounting platform 100, and an adjustment component 130 is provided on the other of the rotary reducer 200 and the mounting platform 100. The adjustment component 130 is used to adjust the relative position of the guide component 240 so that the gear center distance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary bearing 300 is adjustable, so as to adjust the meshing clearance between the inner gear ring 310 of the rotary bearing 300 and the output gear 230 of the rotary reducer 200.

[0049] When the slewing device is applied to an operating machine and the operating machine runs for a period of time, the meshing tooth surfaces between the output gear 230 of the slewing reducer 200 and the inner gear ring 310 of the slewing bearing 300 wear, causing the meshing clearance between the output gear 230 and the inner gear ring 310 to increase. The position of the guide component 240 is adjusted by adjusting the position of the adjusting component 130, thereby synchronously adjusting the relative position between the slewing reducer 200 and the slewing bearing 300 to reduce the meshing clearance between the output gear 230 and the inner gear ring 310 to meet the meshing requirements of the output gear 230 and the inner gear ring 310. This can effectively prevent the upper vehicle platform from shaking left and right relative to the lower vehicle due to the meshing clearance between the output gear 230 and the inner gear ring 310 being too large, thereby affecting the use of the operating machine.

[0050] At the same time, when the meshing tooth surfaces between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary support 300 are worn, the corresponding parts do not need to be replaced, and the center distance between the output gear 230 and the inner gear ring 310 can be adjusted to continue to be used. This arrangement is conducive to after-sales maintenance of the rotary device.

[0051] Furthermore, since the relative position between the rotary reducer 200 and the slewing bearing 300 can be adjusted, that is, the meshing clearance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the slewing bearing 300 can be adjusted. Therefore, when installing the rotary device and the lower vehicle of the working machine, a certain clearance can be reserved between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the slewing bearing 300 to avoid interference and collision between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the slewing bearing 300 during the installation process, making the installation process simpler. This can effectively solve the problem in the prior art that, due to the relatively fixed center distance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary support 300, when assembling the mounting platform 100 and the lower vehicle, the mounting platform 100 needs to be rotated to a specific angle in advance so that the tooth top of the output gear 230 of the rotary reducer 200 can be inserted into the tooth groove of the inner gear ring 310 of the rotary support 300, resulting in a cumbersome installation process.

[0052] Continue reading Figure 3 In some embodiments of the utility model, a first mounting position 110 and a second mounting position 120 are provided on the mounting platform 100, the slewing reducer 200 is provided at the first mounting position 110, and the slewing bearing 300 is installed at the second mounting position 120. The first mounting position 110 may be a mounting hole that is provided through the mounting platform 100, and the shape of the mounting hole may be rectangular, circular or elliptical. The second mounting position 120 may be a plurality of connection holes provided on the mounting platform 100 for bolt connection, and the plurality of connection holes are arranged in a circumferential array.

[0053] Among them, the first mounting position 110 is located inside the second mounting position 120 and is arranged close to one side of the second mounting position 120, the guide component 240 or the adjustment component 130 is arranged on both sides of the first mounting position 110, and the symmetry axis of the guide component 240 or the adjustment component 130 is located on the center line of the first mounting position 110 and the second mounting position 120.

[0054] For example, when the guide component 240 is arranged on the rotary reducer 200 and the adjustment component 130 is arranged on the installation platform 100, two adjustment components 130 are symmetrically arranged on both sides of the first installation position 110, and the two adjustment components 130 are parallel to the center line of the first installation position 110 and the second installation position 120, which is equivalent to that the adjustment component 130 is parallel to the adjustment direction of the center distance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the slewing bearing 300, ensuring that the gap between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the slewing bearing 300 can be adjusted along the center distance direction of the output gear 230 and the inner gear ring 310, avoiding that the output gear 230 of the rotary reducer 200 is affected by the meshing of the output gear 230 with the inner gear ring 310 of the slewing bearing 300 after the position of the output gear 230 is adjusted.

[0055] Continue reading Figure 2 and Figure 3 In some embodiments of the present invention, the adjusting member 130 is disposed on the mounting platform 100 and the guiding member 240 is disposed on the rotary reducer 200:

[0056] The adjusting member 130 includes a supporting member 131 and an adjusting member 132. The supporting member 131 is disposed on the mounting platform 100. An adjusting hole 1311 is formed on the supporting member 131. The adjusting member 132 is threadedly connected to the adjusting hole 1311. The end of the adjusting member 132 abuts against the guide member 240. The adjusting hole 1311 is a threaded hole, and the adjusting member 132 can be an adjusting bolt.

[0057] When the rotary device is in use, the position of the rotary reducer 200 can be quickly adjusted by adjusting the screwing depth of the adjusting member 132, so that the center distance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary support 300 can be adjusted, thereby improving the meshing side clearance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary support 300, which is beneficial to the assembly of the operating machinery and after-sales maintenance.

[0058] Continue reading Figure 3 In some embodiments of the present invention, a guide groove 1312 is provided on the support member 131 along the length direction, and the guide component 240 is slidably engaged with the guide groove 1312 .

[0059] The guide component 240 disposed on the rotary reducer 200 is matched with two mutually symmetrically disposed support members 131 on the mounting platform 100 and provided with guide grooves 1312 to be clamped to transmit the output torque of the rotary reducer 200, with high reliability.

[0060] Compared with the related art, the rotary reducer 200 is fixedly connected with the mounting platform 100 by bolts. The rotary reducer 200 transmits torque through the bolts during operation, and the bolts are subjected to impact vibration, which easily causes the bolts to loosen. The mounting component provided by the embodiment of the utility model transmits torque through the guide component 240 and the guide groove 1312 of the support member 131, which has higher reliability and can effectively prevent the rotary reducer 200 from loosening the bolts due to the transmission of torque and impact vibration during operation, thereby affecting the normal use of the rotary reducer 200.

[0061] Continue reading Figure 3 In some embodiments of the present invention, the guide component 240 includes a guide protrusion 241 , the guide protrusion 241 is guided and matched with the support member 131 , and the end of the adjustment member 132 abuts against the guide protrusion 241 .

[0062] Accordingly, a guide groove 1312 that cooperates with the guide protrusion 241 for limiting can be provided on the mounting platform 100, or a support member 131 can be provided on the mounting platform 100, and a guide groove 1312 can be provided on the support member 131. When the rotary reducer 200 is mounted on the mounting platform 100, the guide protrusion 241 and the guide groove 1312 are slidably matched, and the adjustment member 130 is located at both ends of the guide protrusion 241, and can adjust the position of the guide protrusion 241, so that the guide protrusion 241 drives the rotary reducer 200 to move along the extension direction of the guide groove 1312, so as to adjust the relative position between the rotary reducer 200 and the rotary support 300, so as to reduce the meshing clearance between the output gear 230 and the inner gear ring 310, and meet the meshing requirements of the output gear 230 and the inner gear ring 310.

[0063] It should be noted that the adjusting member 132 can also be set as a screw structure, and a threaded hole is opened inside the guide protrusion 241. The guide protrusion 241 and the guide groove 1312 are slidably matched. The screw structure passes through the threaded hole of the guide protrusion 241, and the two ends of the screw structure are connected to the support member 131 through rotating support members such as bearings, so that the screw structure, the guide protrusion 241 and the support member 131 form a screw nut pair. By screwing the screw structure, the guide protrusion 241 can be driven to move along the guide groove 1312, thereby adjusting the position of the rotary reducer 200.

[0064] Continue reading Figure 3 In some embodiments of the present invention, the guide component 240 further includes a limiter 242 , and the limiter 242 is disposed above the guide protrusion 241 and parallel to the guide protrusion 241 .

[0065] When the rotary reducer 200 is installed on the mounting platform 100, the guide protrusion 241 is embedded in the guide groove 1312, and the adjusting component 130 abuts against the limit member 242. By adjusting the position of the limit member 242, the abutment member drives the rotary reducer 200 to move along the extension direction of the guide groove 1312 to adjust the relative position between the rotary reducer 200 and the rotary support 300, so that the meshing clearance between the output gear 230 and the inner gear ring 310 is reduced to meet the meshing requirements of the output gear 230 and the inner gear ring 310.

[0066] In the embodiment of the utility model, the guide protrusion 241 only needs to play a limiting role, and the position of the rotary reducer 200 is adjusted by the limiting member 242 to avoid deformation or damage of the guide protrusion 241 when the adjusting member 130 adjusts the guide protrusion 241, thereby affecting the guiding function.

[0067] Continue reading Figure 3 In some embodiments of the present invention, the guide component 240 also includes a limit member 242, which is arranged parallel to the top of the guide protrusion 241, and the limit member 242 is suitable for overlapping the upper surface of the support member 131, and the end of the adjustment member 132 abuts against the end face of the limit member 242.

[0068] Extensions 2421 are provided near both ends of the limiting member 242 . The extensions 2421 protrude from the upper surface of the limiting member 242 . The ends of the adjusting member 132 abut against the end surfaces of the limiting member 242 and the extensions 2421 .

[0069] When the rotary reducer 200 is installed on the mounting platform 100, the guide protrusion 241 is embedded in the guide groove 1312, and the adjusting component 130 abuts against the limiting lug. By adjusting the position of the limiting component 242, the abutting component drives the rotary reducer 200 to move along the extension direction of the guide groove 1312 to adjust the relative position between the rotary reducer 200 and the rotary support 300, so that the meshing clearance between the output gear 230 and the inner gear ring 310 is reduced to meet the meshing requirements of the output gear 230 and the inner gear ring 310.

[0070] In addition, supporting lugs 1313 are arranged opposite to each other on the supporting member 131, and the adjustment hole 1311 is arranged on the supporting lugs 1313; the distance between the two supporting lugs 1313 arranged opposite to each other is greater than the length of the limiting member 242, so that there is an adjustment gap between the limiting member 242 and the corresponding supporting lugs 1313.

[0071] In the embodiment of the utility model, the guide protrusion 241 only needs to play a limiting role, and the position of the rotary reducer 200 is adjusted by the limiting member 242 to avoid deformation or damage of the guide protrusion 241 when the adjusting member 130 adjusts the guide protrusion 241, thereby affecting the guiding function.

[0073] See also Figure 4 and Figure 5 It should be noted that the rotary reducer 200 includes a main body component 210 and a mounting chassis 220 , and the guide component 240 or the adjustment component 130 is disposed on the mounting chassis 220 .

[0074] When installing the rotating device provided by the embodiment of the utility model, the support member 131 can be first clamped on the guide protrusions 241 on both sides of the mounting chassis 220, and then the combined components are inserted into the first mounting position 110 of the mounting platform 100, and then the support member 131 is welded and fixed on the mounting platform 100.

[0075] The utility model is an improvement on the original rotary device, and improves the mounting chassis 220 and the mounting platform 100 of the rotary reducer 200. An adjustment component 130 is arranged on the mounting platform 100, and the adjustment component 130 includes a support member 131 and an adjustment member 132. The support member 131 is provided with a guide groove 1312 to form a slide rail structure. The adjustment member 132 is threadedly connected to the threaded hole on the support member 131, and the screwing depth of the adjustment member 132 can be adjusted. Among them, the support members 131 are symmetrically arranged in two groups, and the symmetry axes of the two groups of symmetrically arranged support members 131 pass through the center of the output gear 230 of the rotary reducer 200 installed on the mounting platform 100 and the center of the inner gear ring 310 of the rotary bearing 300.

[0076] Mounting planes 221 are provided on both sides of the mounting chassis 220 of the rotary reducer 200, and guide strips or guide protrusions 241 are provided on the mounting planes 221. The guide strips or guide protrusions 241 can be closely matched with the guide grooves 1312 on the support member 131, and the guide strips or guide protrusions 241 can perform translational movement along the guide grooves 1312 to adjust the position of the rotary reducer 200, thereby achieving the purpose of adjusting the center distance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary support 300.

[0077] When the slewing device is applied to the operating machine and works for a period of time, if the measured meshing clearance between the output gear 230 of the slewing reducer 200 and the inner gear ring 310 of the slewing bearing 300 is less than the standard value, the standard value can be set manually based on experience. The adjusting members 132 at both ends of the synchronously rotating support member 131 increase the screwing depth of the adjusting member 132 at one end and reduce the screwing depth of the adjusting member 132 at the other end, so that the slewing reducer 200 is translated in a direction close to the center of the slewing bearing 300 until the measured meshing clearance between the output gear 230 of the slewing reducer 200 and the inner gear ring 310 of the slewing bearing 300 meets the standard value.

[0078] If the measured meshing clearance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary bearing 300 is greater than the standard value, the adjusting members 132 at both ends of the rotating support member 131 are synchronously rotated to increase the screwing depth of the adjusting member 132 at one end and reduce the screwing depth of the adjusting member 132 at the other end, thereby causing the rotary reducer 200 to translate in a direction away from the center of the rotary bearing 300 until the measured meshing clearance between the output gear 230 of the rotary reducer 200 and the inner gear ring 310 of the rotary bearing 300 meets the standard value.

[0079] In addition, when the rotary reducer 200 is in operation, the guide protrusion 241 cooperates with the guide groove 1312 on the support member 131 to limit the rotary reducer 200 in a direction perpendicular to the guide groove 1312, so that the torque transmission effect of the rotary reducer 200 is better, thereby replacing the rotary reducer 200 in the prior art that transmits torque through the bolt pre-tightening force, and effectively avoiding the problem of bolt loosening due to vibration impact.

[0080] In addition, when the installation platform 100 is lowered and assembled with the working machine, the adjusting parts 132 at both ends of the support part 131 can be rotated synchronously, so that the rotary reducer 200 can be translated in a direction close to the center of the rotary bearing 300 until the output gear 230 of the rotary reducer 200 is offset from the inner gear ring 310 of the rotary bearing 300, thereby ensuring that the installation platform 100 and the rotary bearing 300 of the working machine will not collide with each other and the assembly can be carried out smoothly.

[0081] The utility model further provides an operating machine, comprising a machine body and the slewing device described in any one of the above items, wherein the slewing device is arranged on the machine body and is used to install the slewing support 300 of the operating machine.

[0082] The working machine includes any working machine having a slewing support 300 structure, such as a crane and an excavator.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
