Description

Technical Field

[0001] This utility model relates to the field of bearings, and more particularly to long-life full needle roller rod bearings. Background Technology

[0002] Roller rod bearings are an important component in modern industry. They mainly consist of an inner ring, an outer ring, connecting rods, a cage, and rolling elements. Bearings are components that fix and reduce the coefficient of friction of loads during mechanical transmission.

[0003] During operation, mechanical equipment exerts significant wear and mechanical stress on the bearings that connect and transmit power. Furthermore, many devices inevitably experience vibrations during operation. In the case of roller rod bearings, due to their relatively weak load-bearing capacity, they are prone to wear, thus shortening their service life. Moreover, roller rod bearings and connecting columns are often integrated structures, meaning that when the connecting column is damaged, the entire roller rod bearing needs to be replaced, which is wasteful.

[0004] Therefore, given that most existing roller rod bearings and connecting columns are integrated structures, roller rod bearings are not convenient for replacing connecting columns according to different equipment, have low applicability, and require the entire roller rod bearing to be replaced when the connecting column is damaged, which is wasteful, a long-life full-needle roller rod bearing can be designed. When the bearing connecting column is connected to the bearing connecting seat, rotating the knob drives the transmission gear through the transmission disc. The transmission gear meshes with the rack on one side of the clamping block, causing the transmission gear to drive the clamping block to slide inside the movable groove, facilitating the clamping block to clamp and fix the bearing connecting column. Utility Model Content

[0005] To overcome the problems that existing roller rod bearings and connecting columns are mostly integrated structures, making it inconvenient to replace the connecting column for different equipment, resulting in low applicability, and requiring the entire roller rod bearing to be replaced when the connecting column is damaged, which is wasteful.

[0006] The technical solution of this utility model is as follows: a long-life full-needle roller bearing with rod, including a bearing housing, a bearing connecting seat on the inner side of the bearing housing, a connecting base on the top of the bearing connecting seat, a bearing connecting column on the top of the connecting base, three retaining blocks evenly arranged on the top surface of the bearing connecting seat on the outer side of the connecting base, a knob on one side of one of the retaining blocks, a transmission disc on the inner side of the bearing connecting seat at the bottom of the knob, a transmission gear on the inner side of the transmission disc, and a rack on one side of the top of the transmission gear on the retaining block.

[0007] Preferably, when the bearing connecting column is connected to the bearing connecting seat, the knob is rotated, and the knob drives the transmission gear to rotate through the transmission disc. The transmission gear meshes with the rack on one side of the clamping block, so that the transmission gear drives the clamping block to slide inside the movable groove, which facilitates the clamping block to clamp and fix the bearing connecting column.

[0008] Preferably, the bearing connecting column and the connecting base are an integral structure. The bottom end of the connecting base is provided with a positioning groove at the center of the top surface of the bearing connecting seat, and the bottom end of the connecting base is inserted into the inner side of the positioning groove.

[0009] Preferably, the bottom end of the retaining block is provided with a movable groove on the top surface of the bearing connecting seat, and the bottom end of the retaining block extends through the movable groove to the inner side of the bearing connecting seat.

[0010] Preferably, the number of retaining blocks and transmission gears is the same, with three retaining blocks and three transmission gears in total.

[0011] Preferably, the bottom end of the knob extends through the bearing connecting seat to the outer side of the transmission disc, and the bottom end of the knob is provided with a connecting gear, through which the knob is connected to the transmission disc.

[0012] Preferably, the inner wall of the transmission disc and the upper and lower ends of the transmission gear are provided with tooth blocks, the transmission disc and the transmission gear mesh with each other, and the transmission gear meshes with the connecting base.

[0013] Preferably, the retaining block is an L-shaped movable block, and the inner wall of the retaining block has the same shape as the outer side of the connecting base.

[0014] The beneficial effects of this utility model are:

[0015] When the bearing connecting column is connected to the bearing connecting seat, the knob is rotated, and the knob drives the transmission gear to rotate through the transmission disc. The transmission gear meshes with the rack on one side of the clamping block, so that the transmission gear drives the clamping block to slide inside the movable groove, which facilitates the clamping block to clamp and fix the bearing connecting column.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a long-life full needle roller rod bearing, including a bearing housing 1, a bearing connecting seat 2 provided on the inner side of the bearing housing 1, a connecting base 11 provided on the top of the bearing connecting seat 2, a bearing connecting column 3 provided on the top of the connecting base 11, the bearing connecting column 3 and the connecting base 11 are an integral structure, the bottom end of the connecting base 11 is provided with a positioning groove 6 at the center of the top surface of the bearing connecting seat 2, and the bottom end of the connecting base 11 is inserted into the inner side of the positioning groove 6, thereby facilitating the connection of the bearing connecting column 3 and the bearing connecting seat 2;

[0023] Please see Figures 2-3 In this embodiment, three retaining blocks 4 are evenly arranged on the top surface of the bearing connecting seat 2 on the outer side of the connecting base 11. The bottom end of the retaining block 4 is provided with a movable groove 5 on the top surface of the bearing connecting seat 2. The bottom end of the retaining block 4 extends through the movable groove 5 to the inner side of the bearing connecting seat 2. The number of retaining blocks 4 is the same as that of the transmission gear 9. There are three retaining blocks 4 and three transmission gears 9. The retaining block 4 is an L-shaped movable block. The inner wall of the retaining block 4 is the same as the shape of the outer side of the connecting base 11. Thus, the bearing connecting column 3 is fixed by the retaining block 4.

[0024] Please see Figures 2-4 In this embodiment, a knob 7 is provided on one side of one of the holding blocks 4. The bottom end of the knob 7 is located inside the bearing connecting seat 2 and a transmission disc 10 is provided. A transmission gear 9 is provided inside the transmission disc 10. A rack 8 is provided at the top of the transmission gear 9 on one side of the holding block 4. The bottom end of the knob 7 extends through the bearing connecting seat 2 to the outside of the transmission disc 10. A connecting gear is provided at the bottom end of the knob 7. The knob 7 is connected to the transmission disc 10 through the connecting gear. Tooth blocks are provided on the inner wall of the transmission disc 10 and at both ends of the transmission gear 9. The transmission disc 10 and the transmission gear 9 mesh with each other. The transmission gear 9 meshes with the connecting base 11. By rotating the knob 7, the knob 7 drives the transmission gear 9 to rotate through the transmission disc 10. The transmission gear 9 meshes with the rack 8 on one side of the holding block 4, so that the transmission gear 9 drives the holding block 4 to slide inside the movable groove 5, which facilitates the holding block 4 to clamp the bearing connecting column 3.

[0025] During operation, the base of the bearing connecting column 3 is inserted into the inner side of the bearing connecting seat 2. The top of the bearing connecting seat 2 is provided with a positioning groove 6, which facilitates the positioning of the bearing connecting column 3 and the bearing connecting seat 2 when they are connected. Then, by rotating the knob 7, the knob 7 drives the transmission gear 9 to rotate through the transmission disc 10. The transmission gear 9 meshes with the rack 8 on one side of the clamping block 4, so that the transmission gear 9 drives the clamping block 4 to slide inside the movable groove 5, which facilitates the clamping block 4 to clamp and fix the bearing connecting column 3.

[0026] Through the above steps, when the bearing connecting column 3 is connected to the bearing connecting seat 2, the three clamping blocks 4 clamp and fix the bearing connecting column 3 by rotating the knob 7. This solves the problem that most existing roller rod bearings and connecting columns are integrated structures, making it inconvenient to replace the connecting column according to different equipment, resulting in low applicability. Furthermore, when the connecting column is damaged, the entire roller rod bearing needs to be replaced, which is wasteful.
