Description

Technical Field

[0001] The invention relates to the technical field of bearings, and in particular to a pressure-resistant heavy-load bearing. Background Art

[0002] In actual industrial robotic arms and other mechanical equipment, bearings are important connecting components, especially some bearings need to withstand greater pressure, and have higher requirements for the heavy-load resistance of bearings. At present, for the base of the robotic arm and other positions, rotary bearings are needed. They are large in size and do not require high bearing speed. Thanks to the current rotary bearings using more rollers, they have better support and pressure resistance. However, the current pressure-resistant heavy-load bearings are not convenient for switching the pressure position. The actual working conditions of a large number of robotic arm bearings are less than 360 degrees when the inner and outer rings rotate, but some reciprocating workpiece picking and other work are performed. The direction in which the bearings are subjected to greater force is mostly on one side. Long-term use can easily cause large local wear of the shaft, affecting the coaxial accuracy. At the same time, the pads between the rollers are not easy to wear and adapt. After long-term use, the rollers and pads are greatly worn, resulting in reduced accuracy of the gap between the pads and the rollers, reduced pressure resistance, and affecting the overall service life. At the same time, it is not convenient to inject roller oil in sequence, and most of them are single-point oil injection on the inner ring, which is prone to omissions. Summary of the invention

[0038] In the embodiment of the present disclosure, the slewing bearing component 1 also includes: rollers 102, an outer ring 103 and positioning threaded holes 1031. A circle of rollers 102 is rollingly attached to the outer side of the inner ring 101 of the bearing; an outer ring 103 is rollingly attached to the outer side of a circle of rollers 102; the outer ring 103 is located on the outer side of the inner ring 101 of the bearing; there is a gap between the inner ring 101 of the bearing and the outer ring 103; a positioning threaded hole 1031 is opened on the inner side of the outer ring 103; a thread is provided on the lower section of the positioning threaded hole 1031; the outer ring 103 is a gear ring structure; a circle of threaded holes is provided on the outer ring 103, and the teeth on the outer side of the outer ring 103 are used to connect to the driving source; a circle of threaded holes is provided on the outer ring 103 for connecting the mechanical arm by bolts; the roller positioning component 2 includes: a roller positioning shaft 201, a limit ring 2011 and an anti-touch spring 202, and the roller positioning shaft 20 1 is slidably installed on the inner side of the positioning threaded hole 1031; the bottom of the roller positioning shaft 201 is provided with a thread; the thread at the bottom of the roller positioning shaft 201 is used to screw into the thread provided on the lower section of the positioning threaded hole 1031; the roller positioning shaft 201 is used to limit the roller 102; the roller positioning shaft 201 is fixedly sleeved with a limiting ring 2011; the roller positioning shaft 201 is sleeved with an anti-touch spring 202; the anti-touch spring 202 is located between the limiting ring 2011 and the positioning threaded hole 1031; the top of the roller positioning shaft 201 is provided with a groove for docking a flat screwdriver; the ball disassembly and assembly limiting member 3 includes: a ball stopper column 301 and a positioning bolt 302, the ball stopper column 301 is slidably inserted on the bearing inner ring 101; the end of the ball stopper column 301 is flush with the outer side surface of the bearing inner ring 101; the ball stopper column 301 is provided with a through hole;The inner ring 101 of the bearing is threadedly connected with a positioning bolt 302, and the positioning bolt 302 passes through the through hole on the ball retaining column 301. The roller positioning member 2 can facilitate the uniform oiling of each roller of the bearing, avoiding the problem that the roller 102 far away from the oil filling hole in the traditional oiling method is prone to insufficient oiling, and when the inner ring of the bearing is rotated to adjust the oiling position, the rollers are prone to rotate together, and it is not convenient to discharge the old oil more comprehensively. The present structure can have better uniformity during oiling and is simple to operate. The anti-touch spring 202 adopted can prevent the roller positioning shaft 201 from accidentally touching and jamming the roller 102. The ball disassembly and assembly limiter 3 adopted is convenient for the staff to disassemble and install the roller 102. The structure is mature and reliable. The positioning bolt 302 is used to replace the existing pin-limited ball retaining column 301, which is easy to disassemble. The bearing connecting hole 4011 can be installed on the base of the robot arm through the bolt. The outer ring 103 is provided with threaded holes, and the mechanical arm can be connected with bolts. The outer ring gear structure of the outer ring 103 can be driven to rotate by the corresponding driving device, such as installing gears on the servo motor. This structure can also be used as a mechanical arm joint bearing, and the relevant specifications and sizes can be produced according to the use requirements. When the roller 102 needs to be replaced, the ball retaining column 301 can be pulled out by rotating and disassembling the positioning bolt 302. At this time, it is convenient to take out the roller 102. The surface of the installed ball retaining column 301 is aligned with the groove on the outside of the bearing inner ring 101 and the arc is consistent to prevent the roller 102 from rolling. The bearing inner ring 101 is rotated to adjust the oil filling position. When the bearing inner ring 101 is rotated, the roller positioning shaft 201 will limit the roller 102 to prevent the roller 102 from moving together, and no dead angle for oil filling will be generated. The old oil is discharged from the gap between the bearing inner ring 101 and the outer ring 103. ;

[0039] In the disclosed embodiment, the inner ring pressure adjustment member 4 includes: an adjustment seat ring 401 and a bearing connection hole 4011, the adjustment seat ring 401 is rotatably mounted on the bottom of the bearing inner ring 101; the adjustment seat ring 401 is coaxial with the bearing inner ring 101, and a circle of bearing connection holes 4011 is provided on the adjustment seat ring 401; the inner ring pressure adjustment member 4 also includes: a worm 402 and a ball replacement adapter groove 403, the worm 402 is rotatably mounted on the adjustment seat ring 401, and a hexagonal hole is provided at the end of the worm 402; a ball replacement adapter groove 403 is provided on the adjustment seat ring 401; the ball replacement adapter groove 403 is an arc structure, and the ball replacement adapter groove 403 is an arc structure. The matching groove 403 is used to align the ball stopper 301; the worm gear transmission member 5 includes: a driving gear 501 and a worm wheel 502, the bottom of the driving gear 501 is rotatably mounted on the adjusting seat ring 401; the driving gear 501 is meshed with the meshing teeth 1012; a worm wheel 502 is fixedly mounted on the driving gear 501; the worm wheel 502 is meshed with the worm 402; the worm 402 is used to control the rotation of the bearing inner ring 101 on the adjusting seat ring 401, and the worm gear transmission member 5 is used in conjunction with the inner ring pressure adjustment member 4 to adjust the pressure position of the bearing inner ring 101, and can be adjusted regularly according to actual working conditions to improve the overall service life of the bearing. The structure adopts an adjustable bearing inner ring 101 to prevent the bearing inner ring 101 from being compressed at a single position for a long time, causing excessive wear and deformation in some parts. For example, in the actual working condition of the robot arm, when carrying goods, a large number of 90-degree rotation angles are involved in the handling of goods. Under this working condition, one side of the bearing inner ring 101 is prone to long-term pressure, and local deformation is prone to occur. For example, at some load-bearing joints, the upper part of the bearing inner ring 101 will bear the greater downward pressure of the roller 102 and the outer ring 103, and its wear and deformation will be more serious than that at the position with lighter force. The structure can be better applied to large Mechanical equipment such as robotic arms can improve the uniformity of surface wear and deformation of the inner ring 101 of the bearing, increase the overall service life, and reduce the failure rate. The adjustment method of this structure is simple and convenient. The staff can adjust it regularly, or use measuring tools such as calipers. When the coaxiality of the outer ring 103 and the inner ring 101 of the bearing is not up to standard, or when the height difference is large when used horizontally, the worm 402 is controlled to drive the worm wheel 502 to rotate, and the pressure position of the inner ring 101 of the bearing is adjusted. By adjusting the seat ring 401 and the inner ring 101 of the bearing to be connected in a sleeve manner, there is no ball, and no long-term rotation is required. It has higher precision, is more pressure-resistant, and ensures service life.

[0040] Embodiment 2, on the basis of embodiment 1, the ball bearing cushion member 6 comprises: a cushion sleeve 601, a plug-in column 602 and an expansion extrusion bolt 603, the cushion sleeve 601 is provided with a circle, and the circle of cushion sleeve 601 is located between the inner ring 101 and the outer ring 103 of the bearing; the circle of cushion sleeve 601 is provided with hexagonal holes; two plug-in columns 602 are slidably plugged into the cushion sleeve 601, and the two plug-in columns 602 are respectively hexagonal column structures; the inner sides of the two plug-in columns 602 are respectively inclined structures; the cushion sleeve 601 is threadedly connected with an expansion extrusion bolt 603, and the front side of the expansion extrusion bolt 603 is an inclined structure; the front side of the expansion extrusion bolt 603 is squeezed and fitted between the two plug-in columns 602; expansion The tensioning and squeezing bolt 603 is used to squeeze and push the two plug-in columns 602 to expand outward; the ball pad member 6 also includes: a contraction tension spring 604 and a limit plate 605, and the two ends of the contraction tension spring 604 are respectively fixedly installed on the inner sides of the two plug-in columns 602; the limit plates 605 are respectively fixedly installed at the ends of the two plug-in columns 602; the side of the limit plate 605 is provided with a groove; the two sides of a circle of rollers 102 are respectively fitted with the limit plates 605; the limit plates 605 are used to limit a circle of rollers 102 at intervals; the ball pad member 6 also includes: a rotation and toggle anti-skid groove 6011 and an oil guide groove 6051, and a circle of rotation and toggle anti-skid groove 6011 is provided on the pad sleeve 601; the rotation and toggle anti-skid groove 6011 is used to insert a screwdriver to toggle the pad The sleeve 601 rotates; a circle of oil guide grooves 6051 are provided on the limit plate 605; the circle of oil guide grooves 6051 is used to circulate lubricating oil, and the ball pad 6 can be used to adjust the spacing of the limit plate 605 according to the actual wear condition, so as to ensure that the circle of rollers 102 can roll on the inner ring 101 of the bearing with a smaller clearance, thereby avoiding the problem that the traditional roller pads wear out quickly, and the clearance of the circle of rollers 102 is large due to long-term use, which affects the compressive and heavy-load resistance of the bearing. The spacing of the circle of rollers 102 is made more accurate and uniform, and the clearance is smaller, and at the same time, the service life of the limit plate 605 itself is improved, and it does not need to be replaced frequently. The oil guide grooves 6051 used can facilitate the circulation of lubricating oil. When the oil filling bolt 1011 is rotated and disassembled for oil filling, the oil guide groove 6051 can facilitate the oil circulation more conveniently, and the sludge at the place where the limit plate 605 and the roller 102 are attached can be discharged. The expansion adjustment of the two limit plates 605 of the present structure is accurate and flexible, and the structure is compact. Remove the ball stop column 301. If the expansion extrusion bolt 603 is not aligned with the direction of the ball stop column 301, you can insert a screwdriver to turn the anti-skid groove 6011 to rotate the pad sleeve 601, so that the expansion extrusion bolt 603 can be smoothly docked with the screwdriver. Use a screwdriver to rotate the expansion extrusion bolt 603 to squeeze the plug-in column 602. After the inclined plug-in column 602 is compressed, it drives the two limit plates 605 to expand outward and fine-tune.

[0041] The working principle of this embodiment: First, install the bearing connecting hole 4011 through the bolt to the base of the robot arm. The outer ring 103 is provided with a threaded hole, and the robot arm can be connected with the bolt. The outer tooth structure of the outer ring 103 can be driven to rotate by a corresponding driving device, such as a gear installed on a servo motor. When the roller 102 needs to be replaced, the positioning bolt 302 can be rotated to remove the ball stop column 301. The ball stop column 301 can be easily pulled out by welding a steel bar on the pull-out ball stop column 301. At this time, the roller 102 and the ball pad 6 can be easily taken out. By using a bolt cutter to connect the roller positioning shaft 201 and press it down, the bottom of the roller positioning shaft 201 can be screwed into the positioning threaded hole 1031 and extended out of the inner side of the outer ring 103 to limit the roller 102. At this time, the oil filling screw is rotated to remove The bolt 1011 can be inserted into the threaded hole of the oil filling bolt 1011 installation position to fill oil with an oil gun. During the process, the bearing inner ring 101 can be rotated to adjust the oil filling position. When the bearing inner ring 101 is rotated, the roller positioning shaft 201 will limit the roller 102 to prevent the roller 102 from moving together, and no dead angle for oil filling will be generated. The old oil is discharged from the gap between the bearing inner ring 101 and the outer ring 103; through measuring tools such as calipers, when it is measured that the coaxiality of the outer ring 103 and the bearing inner ring 101 is not up to standard, or when the height difference is large when used horizontally, the worm 402 is connected with the hexagonal wrench to control the worm 402 to drive the worm wheel 502 to rotate, thereby driving the meshing teeth 1012 set in meshing with the driving gear 501 to drive the bearing inner ring 101 to rotate on the adjustment seat ring 401 to adjust the main pressure position;

[0042] When the wear gap between the roller 102 and the limit plate 605 is large, the ball replacement adapter groove 403 is aligned with the ball stop column 301 to ensure that the ball stop column 301 is removed. If the expansion extrusion bolt 603 is not aligned with the direction of the ball stop column 301, a screwdriver can be inserted to turn the anti-slip groove 6011 set to rotate the pad sleeve 601, so that the expansion extrusion bolt 603 can be smoothly docked with the screwdriver. At this time, the screwdriver can be used to rotate the expansion extrusion bolt 603 to squeeze the plug-in column 602. After the inclined plug-in column 602 is compressed, it drives the two limit plates 605 to expand outward and fine-tune. The contraction tension spring 604 plays a role in pulling the plug-in column 602 to fit the expansion extrusion bolt 603. A circle of expansion extrusion bolts 603 are rotated in turn, and the rotation amount is adjusted according to the gap size to evenly compensate for the gap between the roller 102 and the limit plate 605.
