Description

Technical Field

[0001] The utility model relates to the technical field of nylon pulleys, in particular to a high-strength nylon pulley for construction machinery. Background Art

[0002] A nylon pulley is a pulley device that is light in weight and convenient for installation at high altitudes. At present, nylon wheels are also widely used in the fields of construction machinery and equipment. Lifting machines and mechanical components in production all need to use nylon wheels, which have the characteristics of light weight, convenient high-altitude installation, good wear resistance, long service life, etc., and are stronger than steel pulleys in strength.

[0003] Existing nylon pulleys are all fixed by adhesives or high-molecular materials to bond the nylon wheel and the bearing. However, such a fixing method is not conducive to the later problems of wear and tear and disassembly. The disassembly and assembly are not convenient enough. Therefore, a high-strength nylon pulley for construction machinery is proposed to facilitate the disassembly and replacement operation between components later, and the disassembly and assembly are convenient. Summary of the Utility Model

[0004] In view of the problems in the prior art, the utility model provides a high-strength nylon pulley for construction machinery to facilitate the disassembly and replacement operation between components later, and the disassembly and assembly are convenient.

[0005] The technical solution adopted by the utility model to solve its technical problems is a high-strength nylon pulley for construction machinery, which includes a nylon pulley body, a bearing hole, and a disassembly and assembly component. A bearing ring is arranged through the bearing hole on the side surface of the nylon pulley body. The disassembly and assembly component includes a disassembly and assembly ring, a first screw hole, a second screw hole, and a disassembly and assembly bolt;

[0006] A pulley groove is formed on the outer peripheral surface of the nylon pulley body, and an anti-slip-off groove is formed on the inner wall of the nylon pulley body corresponding to the inner side of the pulley groove.

[0007] By adopting the above technical solution, the bearing hole is used to facilitate the penetration of the bearing ring, and through the first connection thread, the disassembly and assembly ring is respectively connected to both sides of the bearing ring through the corresponding second connection thread to clamp the nylon pulley body between the disassembly and assembly rings. At the same time, the disassembly and assembly ring is fixed to both sides of the nylon pulley body again through the bolt penetrating the first screw hole and the second screw hole. In case of serious wear of the bearing ring, etc., disassembly and replacement are carried out, and the disassembly and assembly are convenient;

[0008] When in use, through the pulley groove, structures such as steel wires and ropes can be easily inserted. At the same time, due to the anti-slip-off groove on the inner wall of the nylon pulley body corresponding to the inner side of the pulley groove, the steel wire or rope structure can be inserted deeper into the groove, so as to achieve the anti-slip-off effect and be more practical.

[0009] Specifically, a bearing hole is formed at the center position of one side surface of the nylon pulley body.

[0010] By adopting the above technical solution, the bearing hole is utilized to facilitate the penetration of the bearing ring.

[0011] Specifically, disassembly and assembly rings are provided on both sides of the outer periphery of the bearing ring. First screw holes are evenly formed around the center position on the outer periphery of the surface of the disassembly and assembly rings. Second screw holes are formed at positions corresponding to the first screw holes on both side surfaces of the nylon pulley body. The disassembly and assembly rings are fixed to the nylon pulley body through bolts penetrating the first screw holes and the second screw holes.

[0012] By adopting the above technical solution, the disassembly and assembly rings are fixed to both sides of the nylon pulley body again by penetrating bolts through the first screw holes and the second screw holes.

[0013] Specifically, a first connection thread is formed on the outer peripheral surface of the bearing ring, and second connection threads are formed on the inner walls of the disassembly and assembly rings. The disassembly and assembly rings are connected to the first connection thread through the second connection threads.

[0014] By adopting the above technical solution, the first connection thread is utilized to facilitate the disassembly and assembly rings to be respectively connected to both sides of the bearing ring through the corresponding second connection threads to clamp the nylon pulley body between the disassembly and assembly rings.

[0015] Specifically, both the bearing ring and the disassembly and assembly rings are made of stainless steel.

[0016] By adopting the above technical solution, since both the bearing ring and the disassembly and assembly rings are made of stainless steel, the corrosion resistance of the material used is improved.

[0017] Advantages of the present utility model:

[0018] (1) For the high-strength nylon pulley for construction machinery of the present utility model, through the first connection thread, the disassembly and assembly rings are respectively connected to both sides of the bearing ring through the corresponding second connection threads to clamp the nylon pulley body between the disassembly and assembly rings. At the same time, the disassembly and assembly rings are fixed to both sides of the nylon pulley body again by penetrating bolts through the first screw holes and the second screw holes. In case of severe wear of the bearing ring, etc., disassembly and replacement are carried out, and the disassembly and assembly are convenient.

[0019] (2) For the high-strength nylon pulley for construction machinery of the present utility model, during use, through the pulley groove, structures such as steel wires and ropes are easily clamped. At the same time, through the anti-slip-off groove on the inner wall of the nylon pulley body and inside the pulley groove, the steel wire or rope structure is made to sink into a deeper groove position, thereby achieving the anti-slip-off effect and being more practical.
