Description

Technical Field

[0001] This utility model relates to the field of bearings, specifically to a side roller that saves installation space and is easy to adjust. Background Technology

[0002] Given the previous need for eccentric adjustment of side rollers, there are certain limitations on the structural dimensions of the eccentric shaft. The length must meet certain requirements to satisfy the structural design needs. Furthermore, the relatively long shaft dimensions usually cause some inconvenience in the machining of the shaft.

[0003] In the past, the eccentricity of such side rollers was usually adjusted by using an eccentric shaft, such as... Figure 1 As shown, the eccentric shaft (10) is installed in the mounting hole of the baffle (5). The eccentric shaft (10) also needs to reserve a long threaded section to rotate the two locking nuts (6) for adjustment and locking. Therefore, it usually requires a large installation space. Moreover, due to the long length of the eccentric shaft, it brings certain difficulties to the processing of the eccentric shaft. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model proposes a side roller that saves installation space and is easy to adjust. It has a clever design, a reasonable and compact structure, and a very simple adjustment method, which greatly saves installation space and makes the mechanism lightweight.

[0005] The technical solution of this utility model:

[0006] A space-saving and easy-to-adjust side roller includes a mounting shaft, an inner shaft, an outer ring, and rollers. One end of the inner shaft is designed with an eccentric circular groove. The outer side of one end of the mounting shaft is installed in the eccentric circular groove of the inner shaft. The outer ring is installed on the outer side of the inner shaft. Several rollers are designed between the inner shaft and the outer ring. The end of the mounting shaft is designed with nine threaded holes arranged in a ring. The bottom of the eccentric circular groove of the inner shaft is evenly designed with three screw holes. The inner shaft rotates in the threaded holes of the mounting shaft through three screws passing through the three screw holes. The other end of the mounting shaft is welded and fixed to a baffle.

[0007] The inner shaft and outer ring are coaxially mounted, and the eccentric groove of the inner shaft is designed to be eccentric to the shaft center.

[0008] The baffle has a mounting slot. The end of the mounting shaft is inserted into the mounting slot from one side of the baffle. A round hole is designed in the middle of the bottom of the mounting slot and the round hole connects to the other side of the baffle. The end of the mounting shaft near the baffle is welded to the round hole.

[0009] The mounting shaft is provided with a positioning shaft at one end near the baffle. The positioning shaft is integrally formed with the mounting shaft, and the positioning shaft is inserted into the round hole and welded to the round hole.

[0010] The three screw holes are arranged in a ring at 120-degree intervals; the nine threaded holes are arranged in a ring at 40-degree intervals.

[0011] The advantages of this utility model are its ingenious design and reasonable and compact structure. The side roller has the mounting shaft welded to the baffle. Nine threaded holes are evenly distributed on the mounting shaft. An inner shaft with an eccentric groove is made and installed on the mounting shaft. Three screw holes concentric with the mounting shaft are made on the eccentric inner shaft, which makes it easy to lock the inner shaft to adjust the eccentricity when various adjustment amounts are achieved. This design has a very simple adjustment method, which greatly saves installation space and makes the mechanism lightweight. Attached Figure Description

[0015] See attached document Figure 2-3 A space-saving and easy-to-adjust side roller includes a mounting shaft 1, an inner shaft 2, an outer ring 3, and rollers 4. One end of the inner shaft 2 is designed with an eccentric circular groove. The outer side of one end of the mounting shaft 1 is installed in the eccentric circular groove of the inner shaft 2. The outer ring 3 is installed on the outer side of the inner shaft 2. Several rollers 4 are designed between the inner shaft 2 and the outer ring 3. The end of the mounting shaft 1 is designed with nine threaded holes 11 arranged in a ring. The bottom of the eccentric circular groove of the inner shaft 2 is evenly designed with three screw holes 21. The inner shaft 2 is rotated in the threaded holes 11 of the mounting shaft 1 by three screws 7 passing through the three screw holes 21. The other end of the mounting shaft 1 is welded and fixed to the baffle 5.

[0016] The inner shaft 2 and the outer ring 3 are coaxially mounted, and the eccentric groove of the inner shaft 2 is designed to be eccentric to the axis of the inner shaft 2.

[0017] The baffle 5 has a mounting slot 51. The end of the mounting shaft 1 is inserted into the mounting slot 51 from one side of the baffle 5. A round hole 52 is designed in the middle of the bottom of the mounting slot 51 and the round hole 52 is connected to the other side of the baffle 5. The end of the mounting shaft 1 near the baffle 5 is welded to the round hole 52.

[0018] A positioning shaft 12 is provided at one end of the mounting shaft 1 near the baffle 5. The positioning shaft 12 is integrally formed with the mounting shaft 1. The positioning shaft 12 is inserted into the round hole 52 and the positioning shaft 12 is welded to the round hole 52.

[0019] The three screw holes 21 are arranged in a ring at 120-degree intervals; the nine threaded holes 11 are arranged in a ring at 40-degree intervals.

[0020] In use, this utility model involves welding the mounting shaft of the side roller to a baffle. Nine threaded holes are evenly distributed on the mounting shaft. An inner shaft with an eccentrically grooved hole is mounted on the mounting shaft. Three screw holes, concentric with the mounting shaft, are made on the eccentric inner shaft to facilitate locking the inner shaft to adjust the eccentricity for various adjustment amounts. This design offers a very simple adjustment method, significantly saving installation space and making the mechanism lightweight. The mounting shaft of the side roller is welded into the inner hole of the baffle. When adjusting the clearance between the outer ring and the channel steel, the inner shaft is rotated one or more times on the mounting shaft. During adjustment, ensure the screw holes on the inner shaft align with the threaded holes on the shaft, and then lock the inner shaft to the mounting shaft with screws to adjust different eccentricities.
