Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nylon rods, and in particular relates to a nylon rod for a ball mill. Background Art
[0002] Nylon rod is an important engineering plastic that can replace the wear-resistant parts of mechanical equipment and copper and alloy as wear-resistant parts of equipment. It has good toughness, strong wear resistance, oil resistance, shock resistance, tensile strength and good bending strength. It is often used to process various wear-resistant and high-strength parts. The ball mill is driven by a motor to rotate the ball mill to crush the material. The ball mill needs to use nylon rods as the connecting parts of the ball mill coupling.
[0003] The nylon rod commonly used in ball mills is an integrated structure made of nylon material. During installation, the two ends of the nylon rod are respectively inserted into the sockets on the half-coupling. Since the thermal expansion coefficient of the nylon rod is different from that of steel, the gap between the nylon rod and the socket will become loose after a significant temperature change. During rotation, a slight slip will occur between the nylon rod and the socket, thereby aggravating the wear of the nylon rod. Utility Model Content

[0020] like Figure 1-3As shown, a nylon rod for a ball mill comprises a hollow nylon rod body 1 and a metal end head 2. There are two metal end heads 2, which are respectively fixedly connected to the two ends of the nylon rod body 1. A central reinforcing rod 3 is fixedly bonded inside the nylon rod body 1, and the two ends of the central reinforcing rod 3 are respectively fixedly connected to the two metal end heads 2.

Sockets 12 are provided at both ends of the nylon rod body 1, and the side walls of the sockets 12 are provided with slide grooves 13 equidistantly distributed around the axis of the nylon rod body 1.
[0021] According to the above structure, when in use, the two metal end heads 2 are respectively inserted into the corresponding holes of the two half couplings of the ball mill. The metal material of the metal end heads 2 is the same as that of the half couplings. When in use in a cold or high temperature environment, the thermal expansion deformation of the metal end heads 2 is consistent with the thermal deformation of the coupling, avoiding the generation of connection gaps and improving the stability of the connection.

[0023] According to the above structure, during installation, the plug post 22 is inserted into the inside of the plug hole 12, and the slide bar 23 is installed into the inside of the slide groove 13 to prevent the sleeve 21 and the nylon rod body 1 from rotating relative to each other.
