Description

Technical Field

[0001] The utility model relates to the technical field of bearing installation, in particular to a dustproof and self-cleaning bearing. Background Art

[0002] As a key component in mechanical equipment, the working stability and performance of bearings directly affect the efficiency and service life of the equipment. Dust-proof and self-cleaning bearings can effectively protect bearings and ensure their normal operation by preventing dust and pollutants from entering the inside of bearings, thereby extending the service life of equipment. Dust-proof and self-cleaning bearings can keep the inside of bearings highly clean, prevent these tiny particles from damaging the bearings, and ensure the smooth operation and low torque value of the bearings.

[0003] The existing bearing outer ring and bearing seat are generally provided with threaded holes. When the bearing is installed inside the bearing seat, the threaded holes on the bearing outer ring and the bearing seat need to be aligned first. When the threaded holes on the bearing outer ring and the bearing seat are not aligned, the bearing needs to be taken out of the bearing seat and put back in, which makes the installation operation more cumbersome.

[0004] The existing patent (Announcement No.: CN220268242U) is a dust-proof and self-cleaning bearing. The outer ring of the bearing is installed on the bearing base by adopting a connection limit mechanism. The limit slider is inserted into the limit slide groove and slides. When the outer ring of the bearing is installed in a fixed position on the bearing base, the limit card block is inserted into the limit card groove to ensure that the stabilizing screw hole of the outer ring of the bearing is aligned with the stabilizing screw hole of the bearing base, avoiding the problem of the stabilizing screw hole of the outer ring of the bearing and the stabilizing screw hole of the bearing base not being aligned when the outer ring of the bearing is installed in the bearing base, resulting in the outer ring of the bearing being reinstalled, so that the outer ring of the bearing is easily installed in the bearing base, and a connection anti-loosening mechanism is adopted to install the fastening bolt in the stabilizing screw hole, and the anti-loosening plug is inserted into the anti-loosening slot to ensure that the fastening bolt does not rotate in the stabilizing screw hole. The fastening bolt connects the bearing base and the outer ring of the bearing tightly, avoiding the problem of loosening of the fastening bolt due to bearing rotation affecting the tightness of the connection between the bearing base and the outer ring of the bearing, thereby ensuring the tightness of the connection between the bearing base and the outer ring of the bearing.

[0005] In view of the above problems, existing patents have provided solutions, but most existing bearings lack a certain oil drainage structure when oiling and lubricating, so that the oil stays inside for too long, causing aging and oil waste, which can easily affect the internal bearing transmission, and there is a lack of certain protection for the bearings.

[0006] Therefore, a dustproof and self-cleaning bearing is proposed. Utility Model Content

[0030] A dustproof and self-cleaning bearing comprises a bearing base 1, a mounting slot 2 is provided on the inner side of the bearing base 1, and a connecting component 3 is provided on the inner side of the bearing base 1;

[0031] The connecting component 3 includes an oil filling port 301, an oil inlet channel 302, an oil outlet channel 303 and a block 304. The oil filling port 301 is arranged at the top of the bearing base 1, the oil inlet channel 302 is arranged inside the bearing base 1 and is interconnected with the bearing base 1, the oil outlet channel 303 is opened at the bottom of the bearing base 1, the block 304 is arranged inside the oil outlet channel 303, the oil inlet channel 302 is interconnected with the oil filling port 301, and the oil inlet channel 302 and the oil outlet channel 303 are both interconnected with the inner wall of the bearing base 1.

[0032] By setting up the connecting component 3 including the oil filling port 301, the oil inlet channel 302, the oil outlet channel 303 and the blocking block 304, when in use, the lubricating oil is injected into the interior of the bearing base 1 through the oil filling port 301, so that the bearing can run more smoothly. At the same time, after the lubricating oil has been running inside for too long, the old waste oil inside needs to be discharged through the oil outlet channel 303 in time to prevent the bearing from having large rotation friction.

[0033] Specifically, Figure 3 As shown, a bearing outer ring 4 and a bearing inner ring 5 are arranged inside the mounting slot 2 . The bearing inner ring 5 is located on the inner side of the bearing outer ring 4 . A roller 6 is arranged between the bearing outer ring 4 and the bearing inner ring 5 .

[0034] Specifically, Figure 5 As shown, there is a certain gap between the bearing outer ring 4 and the inner side of the mounting slot 2 , and a floating pad 7 is provided between the bearing outer ring 4 and the mounting slot 2 .

[0035] Specifically, Figure 1 As shown, bearing shields 8 are fixedly provided on both sides of the bearing outer ring 4 and the bearing inner ring 5 , and the bearing shields 8 fit the bearing outer ring 4 and the bearing inner ring 5 .

[0036] Specifically, Figure 4As shown, a mounting frame 9 is arranged between the bearing outer ring 4 and the bearing inner ring 5 , and the number of the mounting frames 9 is two groups and they are symmetrically arranged between the bearing outer ring 4 and the bearing inner ring 5 .

[0037] Specifically, Figure 4 As shown, a support groove 10 is provided on one side of the mounting frame 9 , and the position of the rotation axis of the roller 6 corresponds to the position of the support groove 10 .

[0038] Specifically, Figure 2 As shown, fixing grooves 11 are opened at both ends of the bearing base 1 , and fixing bolts 12 are arranged inside the fixing grooves 11 . There are two sets of fixing grooves 11 and fixing bolts 12 , which are symmetrically arranged on both sides of the bearing base 1 .

[0039] Specifically, Figure 4 As shown, a mounting groove 13 is provided inside the mounting frame 9 . The mounting groove 13 is arranged in a circular array inside the mounting frame 9 , and the roller 6 is rotatably arranged inside the mounting groove 13 .

[0040] By setting the bearing outer ring 4 and the bearing inner ring 5, the rotation of the roller 6 is restricted to prevent the roller 6 from jumping when rotating. At the same time, a floating pad 7 is set between the bearing outer ring 4 and the mounting slot 2, which can provide a certain buffer for the radial jump of the bearing and prevent the internal bearing outer ring 4 from causing impact on the bearing base 1. The bearing shields 8 on both sides can provide a certain protection for the inside of the bearing to prevent dust from entering between the bearing outer ring 4 and the bearing inner ring 5. The support groove 10 and the mounting groove 13 on the mounting frame 9 provide a stable base for the installation of the roller 6, and the bearing base 1 can be fixedly installed through the fixing groove 11.

[0041] By adopting the above technical solution, the problem that most existing bearings lack a certain oil drainage structure when oiling and lubricating, so that the oil remains inside for too long and becomes old and wasteful, which easily affects the internal bearing transmission, and at the same time lacks a certain protection for the bearings is solved.

[0042] Working principle: When the present application is in use, lubricating oil is first injected into the interior of the bearing base 1 through the oil filling port 301 to make the bearing run more smoothly. At the same time, after the lubricating oil has been running inside for too long, the old waste oil inside needs to be discharged through the oil outlet 303 in time to prevent the bearing from having large rotation friction. The bearing outer ring 4 and the bearing inner ring 5 limit the rotation of the roller 6. The floating pad 7 can provide a certain buffer for the radial runout of the bearing to prevent the internal bearing outer ring 4 from causing impact on the bearing base 1. The bearing shields 8 on both sides can provide a certain protection for the interior of the bearing to prevent dust from entering between the bearing outer ring 4 and the bearing inner ring 5.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
