BUSHING NYLON WHEEL

WIPO Patent Application WO/2022/104985

A1

A bushing nylon wheel, comprising a bushing and a nylon wheel coaxially sleeved on the outer wall of the bushing. The inner wall of the nylon wheel is in threaded connection with the outer wall of the bushing, and the outer wall of the bushing is provided with at least one exhaust groove which longitudinally penetrates a threaded surface of the bushing and of which the head and tail respectively extend to two end surfaces of the bushing. After the bushing and the nylon wheel are combined by threads, the relative rotation between the two can be effectively prevented, and the relative displacement between the two in the axial direction can also be prevented, and the present invention thus is simple in structure and implementation process; and the exhaust groove enables gas generated between every two threaded grooves when a nylon compound is cured to be discharged through the exhaust groove, effectively avoiding air holes on the threaded connection surface between the nylon wheel and the bushing in a finished nylon wheel, effectively increasing the holding force and bonding force between the nylon wheel and the bushing, and improving the overall performance of the bushing nylon wheel.
