The present invention relates to wheels for a farming machine. The wheels include: a hub part (10) including a coupling hole (101) formed in the center; a liner part (20) formed on a concentric circle with the hub part (10), while being formed into a ring shape with a metal plate of a predetermined thickness; a plurality of spoke parts (30) having one end welded to the outer circumference surface of the hub part (10), and having the other end welded to the inner circumference surface of the liner part (20), and formed radially in a circumferential direction of the outer circumference surface of the hub part (10); a rib part (40) having one end welded to one side of the spoke part (30), and having the other end welded to the inner circumference surface of the liner part (20); and a tread part (50) made of synthetic rubber of a predetermined thickness to be attached as an integrated body through a thermal compression method so as to surround the outer circumference surface of the liner part (20). According to the present invention, since the tread part made of a rubber material is integrated with the liner part made of a metal material through a thermal compression method, the present invention can have an effect of improving durability as well as facilitating mass production while preventing damage to a road surface and a noise from the road surface which can occur during driving, through the rubber tread part.

    본 발명은 농기계용 바퀴에 관한 것으로서, 중심부에 결합공(101)이 형성된 허브부(10); 허브부(10)와 동심 상에 형성되되, 소정 두께의 금속 판재로 되어 환상으로 형성되는 라이너부(20); 일단부는 허브부(10)의 외주면에 용접되고, 타단부는 라이너부(20)의 내주면에 용접되되, 허브부(10)의 외주면 원주 방향을 따라 방사형으로 다수가 형성되는 스포크부(30); 일단부는 스포크부(30)의 일측에 용접되고, 타단부는 상기 라이너부(20)의 내주면에 용접되는 리브부(40); 소정 두께의 합성고무로 되어 상기 라이너부(20)의 외주면을 감싸도록 열압착 방식으로 일체로 부착되는 트레드부(50); 를 포함한다. 본 발명에 따르면, 금속제로 된 라이너부에 고무재로 된 트레드부를 열압착 방식으로 일체로 형성함으로써, 대량생산이 용이하면서도 내구성이 향상됨과 동시에 고무재로 된 트레드부에 의해 주행 중 발생하는 노면소음 및 도로면 손상을 방지할 수 있는 효과가 있다.
