Technical Field
[0001] This utility model belongs to the technical field of tapered roller bearings, specifically a tapered roller bearing that facilitates heat dissipation. Background Technology
[0002] Tapered roller bearings are important mechanical components widely used in various industrial fields. They are separable bearings with tapered raceways on both the inner and outer rings and tapered rollers. This design allows the bearing to withstand both radial and axial loads simultaneously, making it suitable for applications involving combined loads.
[0003] Currently, during the operation of the bearing, a large amount of heat is generated due to the friction between the rollers and the inner and outer rings. If the heat generated by the bearing cannot be dissipated in time, it will cause damage to the tapered roller bearing, thus affecting its normal use. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a tapered roller bearing that facilitates heat dissipation. This solves the problem that during the operation of the bearing, a large amount of heat is generated due to the friction between the rollers and the inner and outer rings. If the heat generated by the bearing cannot be dissipated in time, it will lead to damage to the tapered roller bearing and affect its subsequent normal use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tapered roller bearing for easy heat dissipation, comprising an outer ring, a first positioning hole on one side of the outer ring, a second positioning hole on the other side of the outer ring, a cage installed on the inner side of the outer ring, rollers mounted on the outer ring via the cage, an inner ring installed on the inner side of the cage, and a primary heat-conducting plate and a secondary heat-conducting plate respectively mounted on both sides of the outer ring, each having multiple slots.
[0006] Both the primary and secondary heat-conducting plates are provided with grooves. Multiple first heat-conducting rods are connected to one side of the primary heat-conducting plate. The first heat-conducting rods have slots and are internally threaded with hexagonal socket bolts. Multiple second heat-conducting rods are connected to one side of the secondary heat-conducting plate. Dust covers are installed on both the primary and secondary heat-conducting plates. Multiple heat sinks are connected to the grooves.
[0007] As a further embodiment of this utility model: multiple locking blocks are connected to the dust cover, a spring is connected inside the locking block, a fixing block is connected to one end of the spring, and the side of the fixing block away from the spring is designed with an arc-shaped surface.
[0008] As a further embodiment of this utility model: a fixing groove is provided on both sides of the groove wall of the card slot, the card block is fitted into the card slot, and the fixing block is fitted into the fixing groove.
[0009] As a further embodiment of this utility model: the first positioning hole and the second positioning hole are interconnected, the first heat-conducting rod is inserted into the first positioning hole, and the second heat-conducting rod is inserted into the second positioning hole.
[0010] As a further embodiment of this utility model: the heat sink is generally designed in an arc shape, and thermal grease is applied to one side of both the main heat plate and the secondary heat plate.
[0011] As a further embodiment of this utility model: one end of the second heat-conducting rod is inserted into the slot, and a threaded hole is provided at one end of the second heat-conducting rod, and the internal hex bolt is threadedly connected to the threaded hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This heat-dissipating tapered roller bearing, through the setting of a first positioning hole, a second positioning hole, a first heat-conducting rod, a second heat-conducting rod, a slot, and a heat sink, allows the operator to install the first and second heat-conducting rods into the first and second positioning holes respectively, while simultaneously inserting one end of the second heat-conducting rod into the slot. Then, the operator uses an Allen wrench to tighten the Allen bolt, causing the Allen bolt to connect with the threaded hole, thereby fixing the first and second heat-conducting rods together. This allows the main heat-conducting plate and the auxiliary heat-conducting plate to be attached and fixed to both sides of the bearing's outer and inner rings respectively. Thus, the first and second heat-conducting rods, as well as the main and auxiliary heat-conducting plates themselves, absorb the heat generated on the bearing's outer and inner rings during operation, which is then dissipated by the heat sink, preventing damage due to excessive temperature.
[0014] 2. This heat-dissipating tapered roller bearing features a locking block, locking groove, spring, fixing block, fixing groove, and dust cover. When the operator pushes the locking block into the locking groove, the groove wall pushes against the fixing block through the arc-shaped surface of the fixing block, causing the fixing block to slide into the locking block and compress the spring. Then, after the dust cover contacts the main or secondary heat-conducting plate, the spring's rebound causes the fixing block to engage in the fixing groove, securing the dust cover to the main or secondary heat-conducting plate and covering the heat sink. This ensures the heat sink remains in contact with air while reducing dust ingress, preventing dust buildup from affecting heat dissipation. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a tapered roller bearing that facilitates heat dissipation, including a bearing outer ring 1, a first positioning hole 2 on one side of the bearing outer ring 1, and a second positioning hole 3 on the other side of the bearing outer ring 1. The first positioning hole 2 and the second positioning hole 3 are interconnected. A first heat-conducting rod 11 is inserted into the first positioning hole 2, and a second heat-conducting rod 14 is inserted into the second positioning hole 3. Through the mutual insertion of the first heat-conducting rod 11, the second heat-conducting rod 14 with the first positioning hole 2 and the second positioning hole 3, the first heat-conducting rod 11 and the second heat-conducting rod 14 can directly contact the bearing outer ring 1, thereby transferring working heat.
[0022] A cage 4 is installed on the inner side of the outer ring 1 of the bearing. Roller components 5 are installed on the outer ring 1 of the bearing through the cage 4. The inner ring 6 of the bearing is installed on the inner side of the cage 4. A main heat plate 7 and a secondary heat plate 8 are installed on both sides of the outer ring 1 of the bearing. Multiple slots 9 are provided on both the main heat plate 7 and the secondary heat plate 8. Fixing slots 20 are provided on the side walls of the slots 9. The locking block 17 is engaged with the slot 9, and the fixing block 19 is engaged with the fixing slot 20. Through the engagement of the locking block 17 and the slot 9, the staff can quickly complete the positioning and installation of the dust cover 15 and prevent the installation from being crooked.
[0023] Both the main heating plate 7 and the secondary heating plate 8 are provided with grooves 10. Multiple first heating rods 11 are connected to one side of the main heating plate 7. The first heating rods 11 have slots 12. One end of the second heating rod 14 is inserted into the slot 12. One end of the second heating rod 14 has a threaded hole 22. The hexagonal bolt 13 is threaded into the threaded hole 22. The bolted connection between the hexagonal bolt 13 and the threaded hole 22 makes it easy for the staff to fix the first heating rods 11 and the second heating rods 14, thereby preventing the main heating plate 7 and the secondary heating plate 8 from detaching and falling off. The operation is simple.
[0024] The first heat-conducting rod 11 is internally threaded with an internal hex bolt 13. Multiple second heat-conducting rods 14 are connected to one side of the secondary heat-conducting plate 8. Dust covers 15 are installed on both the primary heat-conducting plate 7 and the secondary heat-conducting plate 8. Multiple locking blocks 17 are connected to the dust covers 15. Springs 18 are connected inside the locking blocks 17. A fixing block 19 is connected to one end of the spring 18. The side of the fixing block 19 away from the spring 18 is designed with an arc surface. Through the arc surface on one side of the fixing block 19, the fixing block 19 can be easily pushed, thereby facilitating the installation and removal of the dust cover 15 by the staff.
[0025] Multiple heat sinks 16 are connected inside the groove 10. The heat sinks 16 are generally arc-shaped. Thermal grease 21 is applied to one side of the main heat plate 7 and the secondary heat plate 8. The arc-shaped design of the heat sinks 16 can increase the contact area with the air, thereby improving the heat dissipation efficiency. The thermal grease 21 can improve the heat transfer efficiency.
[0026] The working principle of this utility model is as follows:
[0027] During assembly, the workers insert the first heat-conducting rod 11 and the second heat-conducting rod 14 into the first positioning hole 2 and the second positioning hole 3, respectively. At this time, one end of the second heat-conducting rod 14 will be inserted into the slot 12. Then, the workers use an Allen wrench to tighten the Allen bolt 13, causing the Allen bolt 13 to be threaded into the threaded hole 22, thereby fixing the first heat-conducting rod 11 and the second heat-conducting rod 14 together. This allows the main heat-conducting plate 7 and the secondary heat-conducting plate 8 to be attached and fixed to both sides of the bearing outer ring 1 and the bearing inner ring 6, respectively. Finally, the retaining block 17 is pushed into the retaining groove 9. During the pushing process, the fixing block 19 is pushed into the inside of the locking block 17 to compress the spring 18. Thus, after the dust cover 15 comes into contact with the main heat plate 7 or the secondary heat plate 8, the spring 18 rebounds and the fixing block 19 is locked into the fixing groove 20, fixing the dust cover 15 on the main heat plate 7 or the secondary heat plate 8. During operation, the heat generated on the outer ring 1 and the inner ring 6 of the bearing is absorbed by the first heat-conducting rod 11, the second heat-conducting rod 14, and the main heat plate 7 and the secondary heat-conducting plate 8 themselves, and transferred to the heat sink 16 for dissipation to reduce the temperature.
