Embodiment 1

[0026] A crawler treadmill roller, such as figure 1 As shown, it includes a roller wheel main body 1 made of hard plastic, and a flexible layer 2 made of soft rubber wrapped around the roller wheel main body 1 .

[0027] Such as figure 1 As shown, the flexible layer 2 adopts soft rubber, preferably polyurethane in this embodiment. The polyurethane elastomer not only has the high elasticity of rubber, but also has the high strength of plastic, and has excellent oil resistance, impact resistance, low temperature resistance, and ozone resistance. , radiation resistance and load-bearing heat insulation and other advantages.

[0028] Such as figure 1 As shown, the roller wheel body 1 is made of hard plastic, preferably polypropylene in this embodiment; polypropylene has good impact resistance, which can ensure the stable operation of the treadmill.

[0029] The preparation process of the drum comprises the following steps:

[0030] Step 1: Inject polypropylene into the roller m...

Embodiment 2

[0037] A crawler treadmill, including a roller and a running belt 3, the roller adopts the roller disclosed in Embodiment 1, and the running belt 3 is sleeved on the roller, so as to complete the fixing between the roller and the running belt 3.

Abstract

The invention relates to a track treadmill roller. The roller comprises a roller wheel body made of hard plastic and a flexible layer made of soft rubber wrapped around the roller wheel body. The roller wheel made of metal or hard plastic in the prior art is modified to be internally molded from the hard plastic and externally wrapped by soft PU to form a double-layer roller wheel structure; in contrast, the structure makes the quality and density of the whole roller small, since the interior is still made of the hard plastic, the overall hardness does not change, the outside is made of the soft rubber, the hardness is low, during the work, when the roller wheel cooperates with a running belt, the resistance is smaller, the track treadmill can be made smoother during the movement, and thestructure conforms to ergonomic and reduces the damage to the knee during running.

Description

technical field [0001] The invention relates to a treadmill part, in particular to a crawler treadmill roller and a crawler treadmill. Background technique [0002] Treadmill is a regular fitness equipment for families and gyms, and it is the simplest type of home fitness equipment today, and it is the best choice for home fitness equipment; in 1965, Nordic Finland Dontley gave birth to the world's first household treadmill. The designer changed it according to the principle of the transmission belt. [0003] Existing crawler treadmill mainly is made of roller wheel and running belt, and running belt is to be made up of top layer PVC rubber, middle layer polyester silk screen, and bottom warp and weft yarn. The roller wheels are made of metal or hard plastic. The overall hardness of such roller wheels is relatively high, which not only makes the overall weight heavier, but also affects the overall smoothness of the treadmill. Contents of the invention [0004] The object...
