Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to an outer spherical bearing for a seed drill disc. Background Art
[0002] The outer side of the outer bearing ring of the outer spherical bearing is an outer spherical structure. The outer spherical bearing plays a role in aligning the heart in the corresponding concave spherical surface of the bearing seat. The seed drill disc uses an outer spherical bearing to adapt to radial loads and axial loads.
[0003] The height of the seeder disc is relatively low and relatively close to the ground. During the sowing process of the seeder disc, the equipment will simultaneously dig trenches on the ground and then cover the soil after sowing. The trenching and covering processes during the sowing process will generate a lot of dust. Since the height of the seeder disc and the bearing are relatively close to the ground, the dust can easily enter the inside of the bearing. The entry of dust into the bearing will accelerate the wear of the bearing. After the dust and grease are mixed, the fluidity of the grease is low, the grease is more likely to solidify, and the lubricating effect of the grease is greatly reduced, resulting in the bearings used in the seeder disc being more easily worn and the bearing life of the seeder disc being short. Summary of the Invention
[0004] The disclosed embodiment relates to an outer spherical bearing for a seed drill disc, wherein an inner brush ring covers the junction between the inner sealing plate and the outer spherical bearing ring, thereby enhancing the sealing ability of the junction between the inner sealing plate and the outer spherical bearing ring, reducing the ingress of dust into the interior of the outer spherical bearing ring, and reducing the accelerated wear of the outer spherical bearing ring caused by dust. The axial movement of the outer sliding bar promotes the movement of grease inside the oil hole dredging member, thereby facilitating the replenishment of grease inside the outer spherical bearing ring. Grease lubrication reduces the wear of the inner ball, thereby preventing the oil hole dredging member and the grease through-hole from being clogged by grease mixed with dust and solidified.
[0005] In a first aspect of the present disclosure, an outer spherical bearing for a seed drill disc is provided, which specifically includes: an outer spherical bearing ring, an outer reinforced sealing ring and an oil hole dredging piece, wherein outer reinforced sealing rings are attached to both sides of the outer spherical bearing ring, an oil hole dredging piece is provided in the middle of the outer spherical bearing ring, an outer positioning screw is fixedly provided on the outer side of the outer spherical bearing ring, an inner annular array of inner balls is provided in the inner side of the outer spherical bearing ring, the inner balls surround the outer side of the inner bearing ring, the inner sealing plate slides between the outer spherical bearing ring and the inner bearing ring, and the inner balls between the outer spherical bearing ring and the inner bearing ring are positioned by a ball retainer.
[0006] In at least some embodiments, an inner brush ring is provided inside the outer reinforced sealing ring, and fixing screws are fixed on both sides of the outer reinforced sealing ring. The inner brush ring enhances the sealing ability at the junction of the inner sealing plate and the outer spherical bearing ring, reduces the dust from entering the inner part of the outer spherical bearing ring through the gap at the junction of the inner sealing plate and the outer spherical bearing ring, and reduces the accelerated wear of the inner part of the outer spherical bearing ring and the inner ball due to increased dust.
[0007] In at least some embodiments, the fixing screw is threadedly connected to the outer spherical bearing ring, and the inner brush ring fits and covers the outer side of the junction between the inner sealing plate and the outer spherical bearing ring.
[0008] In at least some embodiments, an internal connecting slide is fixedly provided inside the oil hole clearing member, a middle sliding column slides through the middle of the internal connecting slide, a first sliding block is fixedly provided at the head end of the middle sliding column, and an outer sliding strip is fixed on the outside of the middle sliding column.
[0009] In at least some embodiments, a middle support spring is fixedly provided between the middle sliding column and the inner connecting slide, supporting the middle sliding column to move toward the first sliding block, and the middle support spring supports the middle sliding column to move back and forth.
[0010] In at least some embodiments, the oil hole clearing member is fixedly arranged on the inner side of the grease through hole, and the first slider protrudes to the inner side of the outer spherical bearing ring. During the rolling process of the inner ball, the first slider, the middle slider and the outer slider are pushed to move synchronously and compress the middle support spring.
[0011] In at least some embodiments, when the first slider and the inner ball are in sliding contact, the inner ball pushes the first slider to move toward one side of the outer slide bar, and the axial movement of the middle slide column and the outer slide bar promotes the movement of grease inside the oil hole dredging piece, making it easier for grease to be replenished inside the outer spherical bearing ring, thereby avoiding the situation where the oil hole dredging piece and the grease through hole are blocked by grease mixed with dust and solidified.
[0012] The utility model provides an outer spherical bearing for a seed drill disc, which has the following beneficial effects:
[0013] The inner brush ring covers the junction between the inner sealing plate and the outer spherical bearing ring, thereby enhancing the sealing ability of the junction between the inner sealing plate and the outer spherical bearing ring. The seed drill disc is close to the ground and more dust is generated by sowing, ditching and covering the soil, which reduces the dust from entering the inner part of the outer spherical bearing ring, reduces the accelerated wear of the outer spherical bearing ring, and extends the service life of the bearing.
[0014] During the rolling process of the inner ball, the first slider and the outer slider are pushed to move synchronously. The axial movement of the outer slider promotes the movement of grease inside the oil hole dredging piece, which is convenient for the grease to be replenished inside the outer spherical bearing ring. Grease lubrication reduces the wear of the inner ball, avoids the oil hole dredging piece and the grease through hole being blocked by grease mixed with dust and solidified, and avoids the lack of lubricating oil inside the outer spherical bearing ring, which accelerates the wear of the inner ball.

The ring 201 is fitted and covered on the outer side of the junction of the inner sealing plate 104 and the outer spherical bearing ring 1. The outer reinforced sealing ring 2 is fitted on both sides of the outer spherical bearing ring 1. The inner brush ring 201 is provided inside the outer reinforced sealing ring 2. The fixing screws 202 are fixed on both sides of the outer reinforced sealing ring 2. The inner brush ring 201 enhances the sealing ability of the junction of the inner sealing plate 104 and the outer spherical bearing ring 1, reduces dust from entering the inner part of the outer spherical bearing ring 1 through the gap at the junction of the inner sealing plate 104 and the outer spherical bearing ring 1, and reduces the accelerated wear of the inner part of the outer spherical bearing ring 1 and the inner ball 103 due to increased dust.
[0029] The inner portion of the oil hole dredging member 3 is provided with an inner connecting slide 305 fixedly provided inside the oil hole dredging member 3, and a middle sliding column 301 slides through the middle of the inner connecting slide 305, and a first sliding block 302 is fixedly provided at the head end of the middle sliding column 301, and an outer sliding bar 303 is fixedly provided on the outer side of the middle sliding column 301, and a middle supporting spring 304 is fixedly provided between the middle sliding column 301 and the inner connecting slide 305, supporting the middle sliding column 301 to move toward the side of the first sliding block 302, and the middle supporting spring 304 supports the middle sliding column 301 to move back and forth, and the oil hole dredging member 3 is fixedly provided on the inner side of the grease through hole 102, and the first sliding block 302 protrudes to the inner side of the outer spherical bearing ring 1. During the rolling process of the inner ball 103, the first sliding block 302, the middle sliding column 301 and the outer sliding bar 303 are pushed to move synchronously and compress the middle supporting spring 304.
[0030] In the embodiment of the present disclosure, Figure 3 and Figure 5As shown, when the first slider 302 and the inner ball 103 are in sliding contact, the inner ball 103 pushes the first slider 302 to move toward the side of the outer slide 303, and the axial movement of the middle slide column 301 and the outer slide 303 promotes the movement of grease inside the oil hole dredging member 3, making it easier for grease to be replenished inside the outer spherical bearing ring 1, and avoiding the situation where the oil hole dredging member 3 and the grease through hole 102 are blocked by grease mixed with dust and solidified.
[0031] Example 2: Based on Example 1, the outer slide 303 and the middle slide column 301 are connected in a sliding manner, the outer slide 303 and the inner connecting slide 305 are connected in a circumferential rotational direction, the middle slide column 301 is provided with a spiral shape to slide with the outer slide 303, and the spiral shape of the middle slide column 301 guides the outer slide 303 to move in a circumferential direction, so that the outer slide 303 is driven to rotate in a circumferential direction while the middle slide column 301 moves axially, thereby improving the ability of the outer slide 303 to clear the grease through hole 102.
[0032] The working principle of this embodiment is: the outer spherical bearing ring 1 is installed in the bearing seat of the seed drill disc, and the outer positioning screw 101 is installed in alignment with the groove of the bearing seat. The grease of the bearing seat flows to the inside of the outer spherical bearing ring 1 through the grease through-hole 102 and the oil hole dredging piece 3, and the inner ball 103 is lubricated with lubricating oil. The inner brush ring 201 covers the gap at the junction of the inner sealing plate 104 and the outer spherical bearing ring 1, and the inner brush ring 201 enhances the sealing ability of the junction of the inner sealing plate 104 and the outer spherical bearing ring 1. The seed drill disc is close to the ground and there is a lot of dust generated by sowing, ditching and covering the soil. The dust is reduced from entering the inner spherical bearing ring 1 through the gap at the junction of the inner sealing plate 104 and the outer spherical bearing ring 1, reducing the situation where the inner spherical bearing ring 1 and the inner ball 103 are accelerated by dust. The dust in the working environment of the outer spherical bearing ring 1 and the inner ball 103 is controlled, thereby extending the service life of the bearing.
[0033] The middle support spring 304 supports the middle sliding column 301 and the first slider 302 to move and protrude to the inner side of the outer spherical bearing ring 1. The first slider 302 protrudes to the inner side of the outer spherical bearing ring 1. During the rolling of the inner ball 103, the first slider 302, the middle sliding column 301 and the outer slider 303 are pushed to move synchronously and compress the middle support spring 304. The axial movement of the middle sliding column 301 and the outer slider 303 promotes the movement of grease inside the oil hole dredging member 3, which is convenient for grease to be replenished inside the outer spherical bearing ring 1. Grease lubrication reduces the wear of the inner ball 103, avoids the oil hole dredging member 3 and the grease through hole 102 being blocked by grease mixed with dust and solidified, and the interior of the outer spherical bearing ring 1 lacks lubricating oil, which accelerates the wear of the inner ball 103.
