Technical Field

[0001] This utility model relates to the field of MC nylon wheel technology, and in particular to a wear-resistant MC nylon wheel. Background Technology

[0002] In the oilfield machinery industry, over 80% of pulley systems operate outdoors. Currently, cast iron pulleys are widely used, which are heavy, prone to rust, and come into direct contact with the wire rope, reducing the rope's lifespan and making replacement difficult. MC nylon, on the other hand, is lightweight and possesses advantages such as self-lubrication and good chemical stability. Therefore, it requires no lubrication, is easy to replace, and protects the wire rope.

[0003] In existing nylon wheels, the width of the groove is usually fixed, which limits its applicability. Furthermore, when the size of the pull rope is too small and does not match the size of the groove, the pull rope tends to swing inside the groove, increasing wear and reducing its efficiency.

[0004] Therefore, it is necessary to propose a wear-resistant MC nylon wheel to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant MC nylon wheel to solve the problems of existing nylon wheels, where the width of the wheel groove is usually fixed, which limits its applicability, and when the pull rope size is small and does not match the wheel groove size, the pull rope is prone to swinging inside the wheel groove, increasing wear and reducing efficiency.

[0025] This utility model provides, for example Figures 1-5 The wear-resistant MC nylon wheel shown includes a wheel body 1, which includes an inner sleeve 101 and an outer sleeve 102. The outer sleeve 102 is installed outside the inner sleeve 101. The inner sleeve 101 may be made of stainless steel, but is not limited to stainless steel. The outer sleeve 102 is made of MC nylon, which has the characteristics of high strength, wear resistance, and heat aging resistance.

[0026] To improve the connection stability between the inner sleeve 101 and the outer sleeve 102, a groove 6 is integrally formed on the inner ring of the outer sleeve 102, and a protrusion 11 is integrally formed on the outer wall of the inner sleeve 101. The protrusion 11 and the groove 6 are engaged and matched, and multiple sets of protrusion 11 and groove 6 can be provided.

[0027] The protrusion 11 and the groove 6 are provided to improve the stability of the connection between the inner sleeve 101 and the outer sleeve 102, thereby improving the service strength of the MC nylon wheel.

[0028] To accommodate different sizes of pull cords, a limiting component is provided on the outer ring of the outer jacket 102. The limiting component includes a fixed ring 2 and a movable ring 3. The fixed ring 2 and the movable ring 3 can be made of, but are not limited to, MC nylon material and can be adjusted according to specific circumstances. The fixed ring 2 is fixedly connected to the outer ring of the outer jacket 102, and the movable ring 3 is slidably disposed on the outer ring of the outer jacket 102. A groove 4 is formed between the fixed ring 2 and the movable ring 3.

[0029] In the prior art, the width of the groove 4 is usually fixed. When using a smaller pull rope, the pull rope tends to swing left and right (along the axial direction of the outer sleeve 102) inside the groove 4, which increases wear on the outer ring of the outer sleeve 102. However, in this invention, the movable ring 3 is slidably set on the outer ring of the outer sleeve 102, making the width of the groove 4 adjustable, suitable for pull ropes of various sizes, and ensuring the applicability of the MC nylon wheel. At the same time, the appropriate width of the groove 4 can control the swing range of the pull rope, preventing the pull rope from swinging left and right significantly inside the groove 4, thus reducing wear.

[0030] To adjust the position of the movable ring 3, an adjustment component for adjusting the position of the movable ring 3 is provided on the outside of the wheel body 1, and the axial length of the inner sleeve 101 is greater than the axial length of the outer sleeve 102 to ensure that the adjustment component can be installed.

[0031] In specific settings, the adjusting components include a threaded sleeve 5 and a connecting frame 7. The threaded sleeve 5 is threadedly connected to the inner sleeve 101, that is, the outer ring of the inner sleeve 101 is provided with an external thread, and the inner ring of the threaded sleeve 5 is provided with an internal thread (not shown in the figure). The external thread and the internal thread are matched, and the friction coefficient between the external thread and the internal thread is appropriate, so that there will be no random rotation. The connecting frame 7 is fixedly connected to the threaded sleeve 5, and the movable ring 3 is fixedly connected to the connecting frame 7. Multiple connecting frames 7 can be set. The connecting frame 7 is made of high-strength material, such as stainless steel, to ensure the connection strength between the threaded sleeve 5 and the movable ring 3.

[0032] Specifically, when the operator rotates the threaded sleeve 5, it moves away from the outer sleeve 102, causing the movable ring 3 to move synchronously through the connecting frame 7, thus widening the width of the wheel groove 4; conversely, when the threaded sleeve 5 is rotated in the opposite direction and moves towards the outer sleeve 102, it causes the movable ring 3 to move synchronously through the connecting frame 7, thus narrowing the width of the wheel groove 4.

[0033] To ensure the stability of the movable ring 3, a limiting component is provided between the threaded sleeve 5 and the inner sleeve 101. The limiting component includes a first threaded hole 8, a screw 9, and a second threaded hole 10. The first threaded hole 8 is opened on the threaded sleeve 5, and the screw 9 is threadedly connected to the inside of the first threaded hole 8. The screw 9 is threadedly engaged with the second threaded hole 10.

[0034] Multiple second threaded holes 10 are provided, and the multiple second threaded holes 10 are distributed in a spiral shape, which conforms to the characteristic that the threaded sleeve 5 drives the screw 9 to move in a spiral shape, so that after the threaded sleeve 5 is rotated and adjusted, the screw 9 can cooperate with the corresponding second threaded hole 10.

[0035] Specifically, loosen screw 9 so that it is pulled out of the corresponding second threaded hole 10, then rotate threaded sleeve 5 to adjust the position of movable ring 3; after adjustment, turn screw 9 in the opposite direction so that screw 9 extends into the corresponding second threaded hole 10 to limit threaded sleeve 5, thereby preventing movable ring 3 from sliding freely.

[0036] The limiting component is set to cooperate with the threaded sleeve 5 to limit the threaded sleeve 5, ensuring the stability of the movable ring 3 and further improving the efficiency of the MC nylon wheel.

[0037] The end of the inner sleeve 101 is provided with multiple marks 12, which are distributed one-to-one with multiple second threaded holes 10. By setting the marks 12, after the operator rotates the threaded sleeve 5, the control screw 9 corresponds to one of the marks 12, that is, the screw 9 can cooperate with the second threaded hole 10 corresponding to the mark 12.

[0038] For example, by aligning screw 9 with one of the marks 12, and adjusting it to correspond with an adjacent mark 12, the width of the wheel groove 4 can be adjusted by 2mm. This width can be adjusted according to the specific usage.
