The stresses of the link type mesh belt and the link type mesh belt not provided with the supporting wheel 21 in the present embodiment are analyzed as follows with reference to fig. 5 and 6:

in the actual use process, the weight G of the weight mainly acts on the chain rod 20, and the chain rod 20 can be subjected to deflection deformation under the action of G. For ease of analysis we reduce the conventional and inventive link mesh belts to fig. 3 and 4, respectively. Where q1 and q2 are uniform loads, l1 and l2 are rod lengths, A, B, C are rollers and support wheels 21, which can be considered herein as standoffs.

First, deflection analysis was performed on a conventional link-type mesh belt. According to the material mechanics, the load-equally divided simply supported beam has the maximum deflection position at the center, and the maximum deflection is as follows:

where E is the modulus of elasticity, and is related to the material, and I is the moment of area of inertia, and is related to the diameter of the link 20. In the present utility model, the links 20 in both cases are considered to be identical, i.e., the same material, diameter, and length of the links. The uniform load q1 is related to the length of the rod and the load-bearing object weight G, namely:

the maximum deflection for the condition of fig. 5 is:

secondly, the chain rod type net belt is analyzed, the chain rod 20 is equally divided into two parts due to the existence of the supporting wheel 21, each part bears uniform load q2, and the mutual influence during deflection deformation is negligible. Therefore, the net belt of the utility model can be regarded as two simply supported beams during stress analysis, the maximum deflection position is at the center position of each part, and the maximum deflection is as follows:

in the formula, since the link 20 is equally divided, the weight G of the object is equally divided, that is:

maximum deflection for the condition of fig. 6:

it is obvious from the above that the maximum deflection of the chain-rod type net belt added with the supporting wheel 21 is only 1/32 of the original one, which greatly improves the rigidity of the chain rod 20, and means that the chain-rod type net belt can bear heavier objects with the size of about 32 times of the original one on the premise of the same material and size.

It is to be understood that the above examples of the present utility model are provided for clarity of illustration only and are not limiting of the embodiments of the present utility model. Various obvious changes, rearrangements and substitutions can be made by those skilled in the art without departing from the scope of the utility model.
