Abstract
Description
Technical Field
[0001] This application relates to the field of bearing transportation, and in particular to a bearing transfer device. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts and reduce the coefficient of friction during their movement, ensuring their rotational accuracy. They are widely used in automobiles, wind power, mining machinery, and metallurgy.
[0003] Currently, some large bearings are usually coated with grease before leaving the factory to reduce wear during transportation. However, due to the weight and size of large bearings, grease is usually applied manually. The grease needs to be spread evenly on the bearing before it is transported.
[0004] However, due to the large size of large bearings, more grease needs to be applied, and more time is required to spread the grease evenly. After the grease is evenly applied, it needs to be transported by a transfer device. However, most existing transfer devices only have transportation functions. This means that workers always need to spend time to complete the grease spreading before the large bearings can be transferred out of the factory, thus lengthening the production cycle of large bearings. Summary of the Invention
[0005] To shorten the production cycle of large bearings, this application provides a bearing transfer device, which adopts the following technical solution: The invention includes a handle and a traveling mechanism, with the handle mounted on the traveling mechanism. The traveling mechanism comprises a mounting base and at least two traveling units. Each traveling unit includes a connecting rod and two rollers. The mounting base has a first support platform and a second support platform, with the second support platform rotatably mounted on the mounting base. The first support platform is annular and sleeved around the second support platform. The first support platform supports the end face of the outer ring of the bearing, and the second support platform supports the end face of the inner ring of the bearing. The second support platform has a positioning unit that abuts against the inner wall of the inner ring of the bearing. When the connecting rod is rotating, the second support platform can drive the inner ring of the bearing to rotate relative to the outer ring of the bearing around the bearing's axis.
[0006] Preferably, the second support platform includes a platform body and an annular support plate. The platform body is cylindrical, and the annular support plate is fitted onto the platform body and connected to the outer wall of the platform body. A slot is provided at the end of the platform body away from the mounting seat, and a positioning element is inserted into the slot. The positioning element is used to drive the positioning unit to abut against the inner wall of the bearing inner ring.
[0007] Preferably, the first support platform has a receiving groove at one end for supporting the outer ring of the bearing, and there are at least two receiving grooves that are symmetrically distributed about the axis of the first support platform.
[0008] Preferably, both the side of the first support platform used to support the outer ring of the bearing and the side of the annular support plate used to support the inner ring of the bearing are provided with flexible anti-slip pads.
[0009] Preferably, the positioning unit includes a first abutment, a second abutment, a positioning rod, and an elastic member. One end of the positioning rod is located in the slot and connected to the first abutment. The other end of the positioning rod passes through the side wall of the platform and is connected to the second abutment. The elastic member is sleeved on the positioning rod. One end of the elastic member is connected to the platform, and the other end of the elastic member is connected to the second abutment.
[0010] Preferably, one of the connecting rods is provided with a first transmission part, the platform is provided with circumferentially distributed transmission teeth, and the mounting base is provided with a transmission component. The transmission component includes a rotating rod, a second transmission part, and a third transmission part. The rotating rod is mounted on the mounting base and can rotate around its own axis. The second transmission part and the third transmission part are both provided on the rotating rod. The second transmission part meshes with the transmission teeth, and the third transmission part meshes with the first transmission part.
[0011] Preferably, a scraper is provided on the outer wall of the platform near the mounting base, and a grease outlet is provided on the mounting base between the platform and the first support platform. A grease collection box is provided on the mounting base at the position corresponding to the grease outlet, and the grease collection box is detachably connected to the mounting base.
[0012] Preferably, the grease reservoir has an opening, through which both the second and third transmission parts can obtain the grease from the reservoir.
[0013] In summary, compared with the prior art, the advantages of this application are as follows: 1. By setting a first support platform to support the outer ring of the bearing and a second support platform to support the inner ring of the bearing on the mounting base, the bearing can be placed on the first support platform and the second support platform. When the traveling mechanism is in the moving state, the second support platform can drive the inner ring of the bearing to rotate relative to the outer ring of the bearing. This allows the grease applied to the bearing to be evenly spread as the inner ring of the bearing rotates. In this process, since the process of evenly spreading the grease occurs simultaneously with the movement of the traveling mechanism, a certain amount of time is saved compared to the method of first applying grease, then spreading it evenly, and finally transporting the bearing. This achieves the effect of shortening the production cycle of large bearings.
[0014] 2. Flexible anti-slip pads are provided on both the side of the first support platform that supports the outer ring of the bearing and the side of the annular support plate that supports the inner ring of the bearing. This not only buffers the impact when the bearing is placed on the first support platform and the annular support plate, thus protecting the bearing, but also increases the friction between the outer ring of the bearing and the first support platform, as well as between the annular support plate and the inner ring of the bearing. This ensures that when the inner ring of the bearing rotates relative to the outer ring, the outer ring of the bearing will not rotate with the inner ring, thereby increasing the stability of the bearing on the first support platform and the annular support plate.

Detailed Implementation
[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0018] Example This application discloses a bearing transfer device, referring to... Figure 1 and Figure 2 The device includes a handle 1 and a walking mechanism 2. One end of the handle 1 is hinged to the walking mechanism 2, and the other end of the handle 1 is for easy gripping by the staff, so that the staff can move the walking mechanism 2 by using the handle 1. The walking mechanism 2 includes a mounting base 201 and at least two walking units 202 located below the mounting base 201. The two walking units 202 are located at both ends of the mounting base 201 along its length and are mounted on the mounting base 201. The walking unit 202 includes a connecting rod 2022 and two rollers 2021. When the staff pulls the handle 1, the rollers 2021 rotate synchronously, and the connecting rod 2022 rotates together with the rollers 2021.
[0019] Reference Figure 1 , Figure 2 and Figure 3 A first support platform 3 and a second support platform 4 are provided on the upper surface of the mounting base 201. The first support platform 3 is annular and is coaxially sleeved on the outside of the second support platform 4. The second support platform 4 includes a platform body 401 and an annular support plate 402. The platform body 401 is cylindrical and can be inserted and fitted with the inner ring of the bearing. The platform body 401 is set on the mounting base 201 and can rotate around its own axis. The annular support plate 402 is located between the first support platform 3 and the platform body 401 and is fixedly sleeved on the platform body 401. When the bearing is placed on the mounting base 201 and needs to be moved, the upper surface of the first support platform 3 abuts against the outer ring of the bearing, and the annular support plate 402 on the platform body 401 abuts against the outer ring of the bearing, thereby supporting the bearing.
[0020] It is worth mentioning that at least two receiving grooves 301 are stacked on the upper surface of the first support platform 3 with the axis of the first support platform 3 as the axis of symmetry. This allows the receiving grooves 301 to provide space for the workers' hands when the outer ring diameter of the bearing is similar to the diameter of the first support platform 3 and the bearing is placed on the first support platform 3 and the annular support plate 402 by manual handling, thereby reducing the risk of workers' hands being crushed when handling the bearing.
[0021] Furthermore, an opening slot (not shown in the figure) can be provided on the annular support plate 402 at the position corresponding to the receiving groove 301. This allows the lifting strap to be pulled out through the opening slot and the receiving groove 301 when the bearing needs to be lifted.
[0022] Reference Figure 2 , Figure 3 and Figure 4Multiple positioning units 403 are arranged circumferentially on the outer wall of the platform 401, and a slot 4011 is provided at the upper end of the platform 401. A positioning member 4012 is inserted into the slot 4011. When the positioning member 4012 is inserted into the slot 4011, the positioning unit 403 can abut against the inner wall of the bearing inner ring. This allows the bearing inner ring to rotate relative to the bearing outer ring while the platform 401 rotates around its own axis on the mounting base 201.
[0023] The positioning unit 403 includes a first abutment 4031, a second abutment 4032, a positioning rod 4033, and an elastic element 4034. The positioning rod 4033 passes through the side wall of the platform 401, and its axis is perpendicular to the axis of the platform 401. One end of the positioning rod 4033 is located inside a slot 4011 on the platform 401 and is fixedly connected to the first abutment 4031. The other end of the positioning rod 4033 is located outside the slot 4011 on the platform 401 and is fixedly connected to the second abutment 4032. The elastic element... 4034 is a spring. The elastic element 4034 is sleeved on the positioning rod 4033. One end of the elastic element 4034 is connected to the outer wall of the platform 401, and the other end of the elastic element 4034 is connected to the second abutment 4032. The first abutment 4031 is a wedge-shaped block made of metal, and the wedge-shaped surface can abut against the positioning element 4012. The second abutment 4032 is a rubber part. This allows the second abutment 4032 to obtain a large friction force when it abuts against the inner wall of the bearing inner ring, and at the same time, it also prevents the inner wall of the bearing inner ring from being easily scratched.
[0024] When the positioning member 4012 is inserted into the slot 4011, the first abutment member 4031 moves towards the side wall of the slot 4011, thereby pushing out the positioning rod 4033. The second abutment member 4032 on the positioning rod 4033 is pressed against the inner wall of the bearing inner ring, and the spring is in a stretched state. When the positioning member 4012 is pulled out from the slot 4011, the spring force causes the positioning rod 4033 to return to its initial position. At this time, the second abutment member 4032 is no longer in contact with the inner wall of the bearing inner ring.
[0025] Reference Figure 1 and Figure 3To prevent the inner ring of the bearing from easily sliding relative to the second abutment 4032, a flexible anti-slip pad 7, which is a rubber pad, is provided on the annular support plate 402. To prevent the outer ring of the bearing from easily rotating on the first support platform 3 when the inner ring rotates, a flexible anti-slip pad 7 is also provided on the first support platform 3. At the same time, since both the annular support plate 402 and the first support platform 3 are provided with flexible anti-slip pads 7, when the bearing is placed on the annular support plate 402 and the first support platform 3, the end face of its outer ring and the end face of its inner ring will not be easily damaged by impact.
[0026] Reference Figure 3 , Figure 5 and Figure 6 To enable the platform 401 to rotate around its own axis when the mounting base 201 is in a moving state, a transmission gear 4013 is provided on its peripheral wall after one end of the platform 401 passes through the mounting base 201 and is located below the mounting base 201. Multiple transmission gears 4013 are provided and circumferentially distributed on the platform 401. A first transmission part 2023, which rotates with the connecting rod 2022, is installed on one of the connecting rods 2022 below the mounting base 201. The first transmission part 2023 is a worm gear mounted on the connecting rod 2022. A transmission component 5 is also provided on the lower surface of the mounting base 201. The transmission component 5 includes a rotating rod 501, a second transmission part 502, and a third transmission part 503. One end of the rotating rod 501 is rotatably mounted on the mounting base 201, and the rotating rod 501 can rotate around its own axis. The second transmission part 502 and the third transmission part 503 are both coaxially fixed on the rotating rod 501. The second transmission part 502 is a gear that can mesh with the transmission gear 4013 on the platform 401. The third transmission part 503 is a gear that meshes with the first transmission part 2023. This means that when the mounting base 201 is in a moving state, since the roller 2021 is in a rotating state, the connecting rod 2022 is also in a rotating state, which drives the first transmission part 2023 to rotate. The first transmission part 2023 can drive the third transmission part 503 and the rotating rod 501 to rotate. When the rotating rod 501 rotates around its own axis, the second transmission part 502 also rotates, thereby driving the platform 401 to rotate around its own axis on the mounting base 201 through the transmission gear 4013 on the platform 401.
[0027] As the inner ring of the bearing rotates relative to the outer ring, the grease applied between the inner and outer rings falls under its own weight. Since the inner ring is rotating relative to the outer ring, the rotor / roller between the inner and outer rings is also rotating. This causes the grease to be evenly spread on the rotor / roller between the inner and outer rings, achieving the effect of spreading the grease evenly.
[0028] Reference Figure 3 , Figure 6 and Figure 7 If a large amount of grease is applied to the bearing, the excess grease will fall onto the space between the platform 401 and the first support platform 3 on the mounting base 201. To reduce this waste, a scraper 4014 is provided on the platform 401, and a grease outlet 2011 is provided on the mounting base 201 between the platform 401 and the first support platform 3. Correspondingly, a grease reservoir 6 is provided below the grease outlet 2011 on the mounting base 201. The grease reservoir 6 is bolted to the mounting base 201. This allows the scraper 4014 to scrape the grease to the grease outlet 2011 when it falls onto the space between the platform 401 and the first support platform 3 on the mounting base 201, so that the grease can fall into the grease reservoir 6 through the grease outlet 2011. The collected grease can then be reused by removing the grease reservoir 6.
[0029] Furthermore, an opening 601 is provided on the side wall of the grease reservoir 6, and the second transmission part 502 and the third transmission part 503 on the transmission member 5 can both contact the lubricating grease in the grease reservoir 6 through the opening 601. This allows lubrication between the second transmission part 502 and the transmission gear 4013, and between the third transmission part 503 and the first transmission part 2023. This reduces wear between the second transmission part 502 and the transmission gear 4013 on the platform 401, and between the third transmission part 503 and the first transmission part 2023, thus achieving the desired effect for the second transmission part 502, the third transmission part 503, the transmission gear 4013, and the first transmission part 2023.
[0030] It should be noted that the same type of grease as bearing grease is pre-applied between the second transmission part 502 and the transmission gear 4013, and between the third transmission part 503 and the first transmission part 2023.
[0031] The implementation principle of this application embodiment is as follows: First, the bearing is placed on the mounting base 201 by manual handling or hoisting, and the end face of the inner ring of the bearing abuts against the annular support plate 402 on the platform 401, while the outer ring of the bearing is placed on the first support platform 3. Subsequently, the positioning member 4012 is inserted and engaged to push the first abutting block, thereby enabling the second abutting block to abut against the inner wall of the inner ring of the bearing, thus completing the fixing of the bearing on the mounting base 201.
[0032] Apply grease to the upper end of the bearing, then pull the handle 1 to move the mounting base 201. At this time, the connecting rod 2022, which is equipped with the first transmission part 2023, begins to rotate around its own axis. The first transmission part 2023 drives the third transmission part 503 to rotate around the axis of the rotating rod 501, and simultaneously drives the third transmission part 503 to start transmission. This causes the platform 401 to rotate around its own axis on the mounting base 201, thereby driving the inner ring of the bearing to rotate relative to the outer ring of the bearing. During the rotation of the inner ring of the bearing, the grease applied to the bearing is gradually spread evenly. Subsequently, the bearing can be directly removed from the mounting base 201 for packaging and loading.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
