Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, and specifically to a friction wheel that is easy to disassemble. Background Technology

[0002] Airport baggage sorting systems use conveyor belts as transport equipment. Internally, multiple conveyor wheels are arranged at intervals along the transport direction. Each wheel is interference-fitted onto the shaft of its corresponding drive motor. Each wheel is driven by its own motor, and together they rub against the back of the conveyor belt, propelling the baggage forward. After prolonged use, the conveyor wheels wear down and need to be removed and replaced. However, because they are installed with an interference fit, disassembly requires force to reverse along the shaft axis, and repeated disassembly can easily wear down the drive motor shaft. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a friction wheel that is fitted onto the outside of a rotating shaft with an interference fit, but can be easily removed from the rotating shaft. The removal operation is labor-saving and does not easily wear the rotating shaft.

[0004] To solve the above problems, this utility model provides a friction wheel that is easy to disassemble. It has a wheel axle hole so that it can be fitted onto the outside of the rotating shaft in an interference fit manner. It is formed by detachably radially splicing at least two wheel parts located on different sides of the motor rotating shaft.

[0005] Furthermore, the friction wheel is specifically formed by detachably radially joining a first half-wheel portion and a second half-wheel portion.

[0006] Furthermore, including the mounting component, the first half-wheel portion and the second half-wheel portion are radially brought together to form a friction wheel, and then each is detachably fixedly mounted to the mounting component, thereby achieving the detachable radial splicing.

[0007] Furthermore, the mounting component is specifically located on the end sides of the first half-wheel portion and the second half-wheel portion.

[0008] Furthermore, the mounting component is annular, and the wheel axle hole is exposed through the hollow hole of the annular mounting component.

[0009] Furthermore, the mounting component has a belt-loading groove on its peripheral side for inserting the timing belt.

[0010] Furthermore, a friction part is detachably mounted on the outer peripheral side of the first half-wheel portion and / or the second half-wheel portion.

[0011] Furthermore, of the outer peripheral side of the first half-wheel portion and / or the second half-wheel portion and the inner peripheral side of the friction portion, one is provided with a locking block and the other is provided with a locking groove. The locking block is detachably locked in the locking groove, and the friction portion is detachably locked onto the outer peripheral side of the first half-wheel portion and / or the second half-wheel portion in this manner.

[0012] Furthermore, the slot has a T-shaped cross-section, and the block also has a correspondingly T-shaped cross-section.

[0013] Furthermore, the end face of the friction part is provided with a wear depth marker for people to judge its wear depth.

[0014] Beneficial effects: The friction wheel is fitted onto the outside of the rotating shaft with an interference fit. When it needs to be disassembled and replaced, each part of the friction wheel can be directly detached radially from the rotating shaft to disassemble the friction wheel. Therefore, the friction wheel of this utility model does not require force to be used to pull the friction wheel out in the opposite direction of the rotating shaft axis as in the prior art. The disassembly operation is labor-saving and does not easily wear the rotating shaft. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to specific embodiments.

[0021] The conveyor belt in an airport's baggage sorting system serves as the transport device. Internally, multiple friction wheels are arranged at intervals along the transport direction. Each friction wheel has an axle hole, allowing it to be fitted with the outer side of its corresponding drive motor shaft via an interference fit. Each friction wheel is driven by its respective drive motor, and together they rub against the back of the conveyor belt, propelling it forward along the transport direction to transport baggage. The specific structure of the friction wheels is detailed below.

[0022] See Figure 1The friction wheel 1 includes a left half-wheel portion 11 and a right half-wheel portion 12. The left half-wheel portion 11 and the right half-wheel portion 12 are preferably made of aluminum alloy material of type 6061-T6, which is wear-resistant and has high tensile strength. To improve the friction effect of the friction wheel 1, a left friction part 13 made of polyurethane (PU) material is installed on the outer peripheral side of the left half-wheel portion 11, as detailed in [details omitted]. Figure 2 , 3 A slot 15, which is T-shaped with a T-shaped cross-section, is formed on the outer circumferential side of the left half-wheel portion 11. Both ends of the slot 15 extend to the right side of the left half-wheel portion 11. A T-shaped locking block 16 extends radially from the inner circumferential side of the left friction portion 13 (in conjunction with...). Figure 3 The locking block 16 is inserted into any slot of the locking groove 15 from its initial end, and advances along the locking groove 15 until the entire locking block 16 is accommodated in the locking groove 15. The left friction part 13 is thus locked onto the periphery of the left half-wheel part 11. Preferably, the locking block 16 of the left friction part 13 and the locking groove 15 of the left half-wheel part 11 are in close contact, generating a large static friction force between them, making relative movement less likely and resulting in good transmission performance. The right half-wheel part 12 and the right friction part 14 are symmetrical to the left half-wheel part 11 and the left friction part 13, and their specific structures are the same as those of the left half-wheel part 11 and the left friction part 13, which will not be described in detail here. In this embodiment, the left half-wheel part 11 is the first half-wheel part and the right half-wheel part 12 is the second half-wheel part. These two half-wheel parts have locking grooves 15, and locking blocks 16 extend from the left friction part 13 and the right friction part 14. Other embodiments may have a groove in the friction part and a locking block extending from the half-wheel part. Furthermore, in other embodiments, the number of half-wheel parts may be more than two.

[0023] The left half-wheel section 11 and the right half-wheel section 12, located on either side, need to be assembled as follows: Figure 1 The friction wheel 1 shown is for this purpose. Figure 2 Both need to be installed at the front end using an annular front mounting piece 2, which is detachably bolted together from an upper half-ring 21 and a lower half-ring 22. The wheel axle hole 17 of the front mounting piece 2 is exposed through the hollow hole of the annular front mounting piece 2 (see...). Figure 1 The left half-wheel portion 11 and the right half-wheel portion 12 are radially brought together to form a friction wheel 1. The left part of the upper half-ring portion 21 is detachably bolted to the upper part of the left half-wheel portion 11, and the right part is detachably bolted to the upper part of the right half-wheel portion 12. The left part of the lower half-ring portion 22 is detachably bolted to the lower part of the left half-wheel portion 11, and the right part is detachably bolted to the lower part of the right half-wheel portion 12. Thus, the left half-wheel portion 11 and the right half-wheel portion 12 are each detachably fixed to the front mounting part 2, and assembled with the help of the front mounting part 2 as follows: Figure 1 The friction wheel 1 is shown. An annular rear mounting member 3 is also provided on the rear ends of both the left half-wheel portion 11 and the right half-wheel portion 12 (see...). Figure 2The rear mounting component 3 is identical to the front mounting component 2, differing only in its installation position, which will not be elaborated here. In this embodiment, the front mounting component 2 (and the rear mounting component 3) are detachably bolted together from the upper half-ring portion 21 and the lower half-ring portion 22. In other embodiments, the front mounting component 2 (and the rear mounting component 3) can be replaced with a single piece. Regardless of whether the front mounting component 2 (and the rear mounting component 3) is separate or integrated, it is located on the end side of the friction wheel 1 rather than inside the friction wheel 1, facilitating user operation and eliminating the need to hollow out the friction wheel 1 to install the front mounting component 2 (and the rear mounting component 3), thus not affecting the rigidity of the friction wheel 1.

[0024] After the friction wheel 1 is assembled, it needs to be assembled using its wheel axle hole 17 (see...). Figure 2 The friction wheel 1 is fitted onto the outside of the drive motor shaft (not shown in the figure, prior art) of the conveyor belt (not shown in the figure, prior art) with an interference fit. Driven by the drive motor shaft, it rubs against the back of the conveyor belt, causing it to move the luggage forward along the conveying direction. The friction wheel 1 can be fitted onto the outside of the shaft using existing methods: first, align the wheel axle hole 17 of the pre-assembled friction wheel 1 with the shaft, then tap the friction wheel 1 with a soft hammer to fit it onto the outside of the shaft. In other embodiments, the friction wheel 1 can be assembled directly on the drive motor shaft without initial assembly. For example, the left half 11 and right half 12 can be brought together radially from the left and right sides of the shaft to form the friction wheel 1 fitted onto the outside of the shaft. Then, as described above, the left half 11 and right half 12 are bolted to the front mounting part 2 (and the rear mounting part 3) to form the friction wheel 1. The assembled friction wheel 1 is then fitted onto the outside of the shaft with an interference fit. See Figure 2 The front mounting part 2 (and the rear mounting part 3) have V-shaped mounting grooves 23 on their circumferential sides. If the number of friction wheels 1 is greater than the number of drive motors in the actual application scenario, a synchronous belt (not shown in the figure) can be used to connect multiple adjacent friction wheels 1 together. The synchronous belt can be installed and accommodated in the mounting groove 23. Multiple friction wheels 1 connected by the synchronous belt can be equipped with only one drive motor. One friction wheel 1 is driven by the shaft of the drive motor, and this friction wheel 1 acts as the driving wheel. The remaining friction wheels 1 act as driven wheels, mounted on their respective shafts (which are not the shafts of the drive motors), and are driven by the synchronous belt to achieve rotation.

[0025] See Figure 3 The front and rear end faces of the left and right friction parts 13 and 14 have grooves 18, which are close to the outer periphery of the left and right friction parts 13 and 14. These grooves serve as wear depth indicators for judging the wear depth of the left and right friction parts 13 and 14. After the friction wheel 1 has been used for a period of time, when its edge wears down to the groove 18, it needs to be disassembled and replaced. To disassemble and replace the worn friction wheel 1, see... Figure 2The user can directly loosen the bolts connecting the left half-wheel portion 11 and the right half-wheel portion 12 to the front mounting part 2 (and the rear mounting part 3), and remove the front mounting part 2 (and the rear mounting part 3) from the left half-wheel portion 11 and the right half-wheel portion 12. The left half-wheel portion 11 and the right half-wheel portion 12 are no longer fixed by the mounting parts 2 and 3, and can be radially outward away from the rotating shaft. The worn friction wheel 1 is then removed from the rotating shaft without the need for forceful operation to retract the friction wheel 1 axially along the rotating shaft as in the prior art. This disassembly operation is effortless and less likely to wear the rotating shaft. After removing the worn friction wheel 1, a new friction wheel 1 can be installed onto the rotating shaft as described above. For the disassembled and worn friction wheel 1, the worn left friction part 13 can be removed from the slot 15 of its left half wheel part 11, and the worn right friction part 14 can be removed from the slot 15 of its right half wheel part 12. New left and right friction parts 13 and 14 can be respectively inserted into the slots 15 of the left half wheel part 11 and the right half wheel part 12 for future use. Since only the left and right friction parts 13 and 14 need to be worn out, while the left half wheel part 11 and the right half wheel part 12 can be reused, costs are saved.

[0026] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
