[0001] This utility model relates to the field of multi-wedge belt idler wheel technology, specifically a multi-wedge belt idler wheel assembly. Background Technology
[0002] Multi-ribbed belt idler pulleys are pulleys in a multi-ribbed belt drive system that do not directly transmit power. Their main function is to assist in transmission, guide, or adjust tension to ensure the stability and efficiency of the transmission system. When multi-ribbed belt idler pulleys are working, the transmission operation is usually achieved by using a multi-ribbed belt to rotate multiple multi-ribbed belt idler pulleys.
[0003] Existing multi-ribbed belt idler pulleys only have one pulley system, and one multi-ribbed belt idler pulley can only be used with one multi-ribbed belt through bearings. This makes the use of multi-ribbed belt idler pulleys inflexible. Therefore, in order to solve the above problems, a multi-ribbed belt idler pulley assembly is proposed. Utility Model Content

[0024] A multi-ribbed belt idler assembly includes a double-row bearing 1, a spacer assembly 2, a first gear train 3, a second gear train 4, and a locking assembly 5. The spacer assembly 2 is provided on the outer side of the double-row bearing 1. The spacer assembly 2 includes a spacer plate 21 installed on the outer side of the double-row bearing 1. The spacer plate 21 has two limiting grooves 22 on both its front and rear sides. The spacer plate 21 has two symmetrically distributed first mounting grooves 23. The first gear train 3 is provided on the rear side of the spacer assembly 2. The first gear train 3 includes a first idler body 31 installed on the outer side of the double-row bearing 1. The front side of the first idler body 31 has two first limiting protrusions 32 with a diameter equal to that of the limiting grooves 22. The first idler body 31 has two symmetrically distributed second mounting grooves 33. The second gear train 4 is provided on the front side of the spacer assembly 2. The second gear train 4 includes a second idler body 41 installed on the outer side of the double-row bearing 1. The rear side of the second idler body 41 has two second limiting protrusions 42 with a diameter equal to that of the limiting grooves 22. The second idler body 41 has two symmetrically distributed third mounting grooves 43.
[0025] A locking assembly 5 is provided on the outer side of the double row bearing 1. The locking assembly 5 includes two locking plates 51 located on the front and rear sides of the double row bearing 1, respectively. Rubber sealing layers 52 are fixedly connected to the opposing sides of the two locking plates 51. Long bolts 53 passing through the locking plates 51 and rubber sealing layers 52 are provided on both the left and right sides of the double row bearing 1. The rear ends of the long bolts 53 are threaded with fastening nuts 54. The locking plates 51 and rubber sealing layers 52 can lock the first idler body 31 and the second idler body 41 onto the double row bearing 1. The opposing sides of the two rubber sealing layers 52 are provided with annular protrusions that match the ends of the double row bearing 1. The opposing sides of the two rubber sealing layers 52 are respectively in contact with the front and rear ends of the double row bearing 1. The long bolts 53 pass through the third mounting groove 43, the first mounting groove 23, and the second mounting groove 33 from front to back. The locking plates 51 and rubber sealing layers 52 are locked onto the front and rear ends of the double row bearing 1 by the long bolts 53 and the fastening nuts 54. The length of the double row bearing 1 in the front-to-back direction is equal to the sum of the lengths of the spacer plate 21, the first idler wheel body 31, and the second idler wheel body 41 in the front-to-back direction. The inner diameter of the double row bearing 1, the inner diameter of the locking plate 51, and the inner diameter of the rubber sealing layer 52 are all equal. The outer diameter of the spacer plate 21 is larger than the outer diameter of the first idler wheel body 31 and the outer diameter of the second idler wheel body 41. The spacer plate 21 can separate the first idler wheel body 31 and the second idler wheel body 41. The front side of the first idler wheel body 31 is attached to the rear side of the spacer plate 21, and the first limiting protrusion 32 is inserted into the limiting groove 22 on the rear side of the spacer plate 21. The rear side of the second idler wheel body 41 is attached to the front side of the spacer plate 21, and the second limiting protrusion 42 is inserted into the limiting groove 22 on the front side of the spacer plate 21. The limiting groove 22 can quickly position the first limiting protrusion 32 and the second limiting protrusion 42, which facilitates the disassembly or replacement of the first idler wheel body 31 and the second idler wheel body 41.
[0026] Working process: Before use, the double-row bearing 1 of the device is installed on the idler wheel axle. Then, a multi-ribbed belt (hereinafter referred to as the first multi-ribbed belt) is fitted onto the outside of the first idler wheel body 31, and another multi-ribbed belt (hereinafter referred to as the second multi-ribbed belt) is fitted onto the outside of the second idler wheel body 41. The device can then be used normally. In the multi-ribbed belt drive system, the first multi-ribbed belt is connected to the driving pulley, and the second multi-ribbed belt is connected to the driven pulley. Therefore, the first idler wheel body 31, together with the driving pulley and the first multi-ribbed belt, can form a transmission system. The first idler wheel body 31 can rotate under the drive of the driving pulley. At the same time, since the spacer plate 21, the first idler wheel body 31, and the second idler wheel body 41 are all mounted on the double-row bearing 1, the device rotates through the spacer plate 21. Plate 21 can separate the first idler wheel body 31 and the second idler wheel body 41 to prevent interference between the first and second multi-wedge belts. The first limiting protrusions 32 are all inserted into the limiting grooves 22 on the rear side of the spacer plate 21, and the second limiting protrusions 42 are all inserted into the limiting grooves 22 on the front side of the spacer plate 21. The limiting grooves 22 can quickly position the first limiting protrusions 32 and the second limiting protrusions 42, facilitating the disassembly or replacement of the first idler wheel body 31 and the second idler wheel body 41. The long bolts 53 pass through the third mounting groove 43, the first mounting groove 23, and the second mounting groove 33 from front to back. The long bolts 53, together with the fastening nuts 54, lock the locking plate 51 and the rubber sealing layer 52. Locked at both ends of the double row bearing 1, the locking plate 51 and the rubber sealing layer 52 can seal the double row bearing 1, preventing foreign objects from entering the double row bearing 1. This prevents the first idler wheel body 31 and the second idler wheel body 41 from dislodging and ensures that the first idler wheel body 31 and the second idler wheel body 41 rotate synchronously and have equal angular velocities. The second idler wheel body 41, together with the driven wheel and the second multi-ribbed belt, can form another transmission system. The driven wheel can rotate under the drive of the second idler wheel body 41. This device can be used simultaneously with two multi-ribbed belts. The models of the first idler wheel body 31 and the second idler wheel body 41 of this device can be selected according to actual needs. Different models of the first idler wheel body... The first idler body 31 and the second idler body 41 can be used with different multi-ribbed belts, so the device can be adapted to various multi-ribbed belts according to actual needs. The device is provided with a first idler body 31 and a second idler body 41 separated by a partition plate 21. The first idler body 31 and the second idler body 41 can be locked on the double row bearing 1 by the locking plate 51 and the rubber sealing layer 52. The first idler body 31 and the second idler body 41 can be used with two multi-ribbed belts at the same time, which greatly improves the flexibility of the device. At the same time, the device can quickly position the first limiting protrusion 32 and the second limiting protrusion 42 through the limiting groove 22, which can be easily and quickly disassembled and assembled.
