Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to a device for reinforcing a looper roller bearing housing. Background Technology

[0002] The main function of slip ring rollers is to support and transmit force while reducing friction and wear. They are commonly used in mechanical equipment such as conveyor belts, conveyors, rolling mills, winding machines, and printing presses to transfer materials or items such as paper.

[0003] Since the looper roller needs to be disassembled and maintained after a period of use, and most of the existing bearing housings are composed of two bearing shells fixed by bolts, it is difficult to ensure the coaxiality between the bearing and the inner arc cavity of the bearing shell after the two bearing shells connected by bolts are disassembled. This can easily lead to a gap between the bearing and the bearing shell, resulting in unstable bearing installation.

[0004] Furthermore, the disassembly efficiency of the two bearing shells connected by bolts is low, making it difficult to improve the efficiency of the loose roller maintenance when disassembling and maintaining the loose roller. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for reinforcing the slip-on roller bearing seat, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A device for reinforcing a slip-on roller bearing seat includes a base, an installation cavity inside the base, a plurality of evenly distributed separation cavities inside the installation cavity, a sliding plate inside the separation cavities, guide rods at both ends of the top of the sliding plate, a bearing tray at the bottom of the sliding plate, and an adjustment mechanism rotatably provided at both ends of the base.

[0008] The adjustment mechanism includes a rotating disk, which is rotatably mounted on the side wall of the base and coaxially arranged with the mounting cavity. Several guide grooves are opened inside the rotating disk, and the positions of the guide grooves correspond one-to-one with the sliding plate. The guide rod is inserted into the guide groove and slidably connected with the guide groove. The base is provided with a drive structure for controlling the adjustment mechanism.

[0009] Furthermore, a bearing ring is fitted onto the outer peripheral wall of the guide rod at the position opposite to the guide groove.

[0010] Furthermore, the bearing tray is arc-shaped, with its outer arc surface fixedly connected to the sliding plate, and its inner arc surface having several evenly distributed anti-slip grooves.

[0011] Furthermore, the drive structure includes a connecting shaft and a control structure. The connecting shaft is rotatably disposed inside the base, and both ends of the connecting shaft are provided with adjusting gears. An external gear ring that meshes with the adjusting gears is fixedly disposed on the outer peripheral wall of the rotating disk.

[0012] Furthermore, the control structure includes a rotating worm gear, which is fixedly installed on the outer peripheral wall of the connecting shaft, and the base has a rotating groove for installing the rotating worm gear. The groove wall of the rotating groove has an adjusting shaft hole, and a control worm is rotatably installed inside the adjusting shaft hole. The control worm cooperates with the rotating worm gear.

[0013] Furthermore, an expansion plate is provided at the bottom of the base, and fixing screw holes are provided at the four corners of the expansion plate.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. This device for reinforcing a slip-on roller bearing seat uses a rotating disc to rotate and, in conjunction with a guide groove inside the disc, pushes a corresponding guide rod, causing a sliding plate to move closer to the central axis of the mounting cavity. This brings the bearing plate into contact with the outer peripheral wall of the bearing, thus fixing the bearing at the end of the slip-on roller. Alternatively, the guide groove can push the guide rod and sliding plate away from the central axis of the mounting cavity, causing the bearing plate to separate from the bearing at the end of the slip-on roller, facilitating the removal of the slip-on roller and effectively achieving the purpose of quick disassembly and assembly of the slip-on roller.

[0016] 2. This kind of looper roller bearing seat reinforcement device has a self-locking characteristic between the rotating worm wheel and the control worm, that is, the rotating worm wheel cannot drive the control worm to rotate. Therefore, after the control worm is rotated to adjust the rotating disk to rotate, the rotating disk can be effectively fixed, thereby further improving the stability of the looper roller connection.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1 - Figure 5 The present invention discloses a device for reinforcing a slip-on roller bearing seat, comprising a base 1, an installation cavity 2 inside the base 1, a plurality of evenly distributed separation cavities 3 inside the installation cavity 2, a sliding plate 4 inside the separation cavity 3, guide rods 5 at both ends of the top of the sliding plate 4, a bearing tray 6 at the bottom of the sliding plate 4, and an adjustment mechanism 7 rotatably provided at both ends of the base 1.

[0027] The adjustment mechanism 7 includes a rotating disk 71, which is rotatably mounted on the side wall of the base 1 and coaxially mounted with the mounting cavity 2. The rotating disk 71 has several guide grooves 72 inside, and the positions of the guide grooves 72 correspond one-to-one with the sliding plate 4. The guide rod 5 is inserted into the guide groove 72 and slidably connected with the guide groove 72. The base 1 has a drive structure 8 for controlling the adjustment mechanism 7 inside.

[0028] In this embodiment, when installing the looper roller, the end of the looper roller with the bearing is inserted into the separation chamber 3 and located between each bearing tray 6. When the bearing position corresponds to the bearing tray 6, the control drive structure 8 drives the adjustment mechanism 7 to rotate, causing the rotating disk 71 to rotate. At this time, the guide groove 72 opened inside the rotating disk 71 pushes the corresponding guide rod 5, causing the sliding plate 4 to move downward until the bearing tray 6 contacts the outer peripheral wall of the bearing, so as to achieve the purpose of fixing the bearing at the end of the looper roller.

[0029] When removing the looper roller, the rotating disk 71 is controlled to rotate by the drive structure 8, and the direction of rotation is opposite to the direction of rotation when the looper roller is installed. At this time, the guide groove 72 can push the guide rod 5 and the sliding plate 4 to move upward. At this time, the bearing tray 6 and the bearing set at the end of the looper roller are separated from each other, so as to facilitate the removal of the looper roller.

[0030] like Figure 1 As shown, a limit baffle is bolted to the back side of the base 1. When the end of the looper roller is inserted into the mounting cavity 2, it is used to limit the end of the looper roller so that the bearing at the end of the looper roller corresponds to the bearing tray 6.

[0031] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a bearing ring is fitted on the outer peripheral wall of the guide rod 5 at the position opposite to the guide groove 72.

[0032] In this embodiment, by setting a bearing ring, the frictional force generated by the guide rod 5 on the guide groove 72 during relative movement between the guide groove 72 and the guide rod 5 is reduced, thereby improving the service life of the guide rod 5 and the guide groove 72.

[0033] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the bearing tray 6 is arc-shaped, the outer arc surface of the bearing tray 6 is fixedly connected to the sliding plate 4, and the inner arc surface of the bearing tray 6 is provided with several evenly distributed anti-slip grooves.

[0034] In this embodiment, the anti-slip groove is used to increase the friction between the outer wall of the bearing and the bearing tray 6, thereby improving the stability of the looper roller after installation.

[0035] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the drive structure 8 includes a connecting shaft 81 and a control structure 82. The connecting shaft 81 is rotatably disposed inside the base 1, and both ends of the connecting shaft 81 are provided with adjusting gears 83. The outer peripheral wall of the rotating disk 71 is fixedly provided with an external toothed ring 84 that meshes with the adjusting gears 83.

[0036] In this embodiment, the connecting shaft 81 is driven to rotate by the control structure 82, which in turn drives the adjusting gears 83 on both sides to rotate. The external gear ring 84 fixedly installed on the outer peripheral wall of the rotating disk 71 is used to control the synchronous rotation of the rotating disks 71 on both sides.

[0037] In a further preferred embodiment of this utility model, such as Figure 3As shown, the control structure 82 includes a rotating worm gear 821, which is fixedly installed on the outer peripheral wall of the connecting shaft 81. The base 1 has a rotating groove 822 for installing the rotating worm gear 821. The groove wall of the rotating groove 822 has an adjusting shaft hole 823. A control worm 824 is rotatably installed inside the adjusting shaft hole 823. The control worm 824 cooperates with the rotating worm gear 821.

[0038] In this embodiment, the adjusting shaft hole 823 and the rotating groove 822 are used to install the rotating worm gear 821 and the control worm 824. Since the control worm 824 cooperates with the rotating worm gear 821, the rotating worm gear 821 can be driven to rotate when the control worm 824 rotates. At the same time, the rotating worm gear 821 is fixedly connected to the connecting shaft 81. Thus, during the rotation of the control worm 824, the connecting shaft 81 and the adjusting gear 83 fixedly connected to the connecting shaft 81 can be driven to rotate.

[0039] Furthermore, since the rotating worm wheel 821 and the control worm 824 have a self-locking characteristic, meaning that the rotating worm wheel 821 cannot drive the control worm 824 to rotate, after the control worm 824 is rotated to adjust the rotating disk 71 to rotate, the rotating disk 71 can be effectively fixed, thereby further improving the stability of the looper roller connection.

[0040] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the bottom end of the base 1 is provided with an expansion plate 9, and the four corners of the expansion plate 9 are provided with fixing screw holes 10.

[0041] In this embodiment, the expansion plate 9 and the fixing screw hole 10 are used to fix the base 1 in the position where it needs to be installed.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
