DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-5 As shown, a nylon track wheel includes a wheel body 7 made of nylon, a first inner groove 5 is opened on one side of the wheel body 7, and a second inner groove 8 is opened on the other side of the wheel body 7. The cross-sections of the first inner groove 5 and the second inner groove 8 are isosceles trapezoids. A through hole 4 is opened at the center of the wheel body 7. The first inner groove 5 and the second inner groove 8 are connected through the through hole 4. A plurality of fixing holes 2 are opened on the inner side of the first inner groove 5 and the plurality of fixing holes 2 extend to the second inner groove 8. Chamfers 6 are opened on both side edges of the wheel body 7.

[0026] In this embodiment, the wheel body 7 is cast from nylon material, and excess nylon material is cut off on both sides of the wheel body 7 to form a first inner groove 5 and a second inner groove 8 and a through hole 4, respectively. When in use, the wheel body 7 is fixed to the frame through the through hole 4 using a rotating shaft and its fixings, and the rotating shaft is fixedly connected to the wheel body 7 through fasteners such as bolts and multiple groups of fixing holes 2. At this time, the wheel body 7 can rotate relative to the frame through the rotating shaft, and the track cooperates with the periphery of the wheel body 7, so that the wheel body 7 guides and transmits the track.

[0027] Among them, Figure 1 , Figure 2 and Figure 3 As shown, a reinforcing rib assembly 1 is arranged in the first inner groove 5, and a plurality of reinforcing rib assemblies 1 are arranged. The plurality of reinforcing rib assemblies 1 are distributed along the circumference of the first inner groove 5, so as to improve the strength of the wheel body 7. The first inner groove 5 is composed of a bottom surface 502 and a side surface 501. The reinforcing rib assembly 1 includes a first connecting block 103 located on the bottom surface 502 and a second connecting block 102 located on the side surface 501. A connecting piece 101 is fixed between the first connecting block 103 and the second connecting block 102. The connecting piece 101 is wedge-shaped. The first connecting block 103, the second connecting block 102, the connecting piece 101 and the wheel body 7 are integrally formed, and the connection is tighter. In addition, during processing, only excess nylon material needs to be cut off, so the forming is easy and the efficiency is high.

[0028] Among them, Figure 1 and Figure 3As shown, the through hole 4 is located in the first inner groove 5 and the second inner groove 8, and flares 3 are respectively provided at both ends thereof. A plurality of sets of fixing holes 2 are equidistantly arranged along the circumference of the flares 3. The rotating shaft passes through the through hole 4. The two end plates used to fix the rotating shaft and the wheel body 7 are respectively located in the two flares 3, and the end plates are provided with connecting holes matching the fixing holes 2. Therefore, the two end plates can be clamped and fixed in the flares 3 by using bolts and the fixing holes 2, and the ends are fixedly connected to the rotating shaft, thereby improving the connection stability between the rotating shaft and the wheel body 7.

[0029] Working principle, first, the rotating shaft passes through the through hole 4, and the two end plates used to fix the rotating shaft and the wheel body 7 are respectively located in the two flares 3, and the end plates are provided with connecting holes matching the fixing holes 2. Therefore, the two end plates can be clamped and fixed in the flares 3 by using bolts and fixing holes 2 (the flares 3 can play a preliminary limiting role in the position of the end plates), and the ends are fixedly connected to the rotating shaft, thereby improving the connection stability between the rotating shaft and the wheel body 7. At this time, the wheel body 7 can rotate relative to the frame through the rotating shaft, and the track cooperates with the periphery of the wheel body 7, so that the wheel body 7 guides and transmits the track, and multiple groups of reinforcing rib assemblies 1 are distributed along the circumference of the first inner groove 5, and the wheel body 7 is cast from nylon, and the reinforcing rib assembly 1 and the wheel body 7 are integrally formed. Therefore, the track wheel has a light weight, and the strength can meet the needs of agricultural machinery. It is simple to process and has low cost.
