When the conveyor is designed to adopt HONGSBELT modular plastic conveyor belt with steel links, the angle between drive shaft and conveyor structure should be accurate in perpendicular, to prevent the deformation of stainless steel rods that would cause the belt to be damaged because of it does not operate in parallel.
Expansion Calculation
Most of objects have the phenomenon of thermal expansion and contraction. Therefore, the phenomenon of thermal expansion and contraction of material caused by temperature change must be considered while designing the conveyor system.

Expansion & Contraction Calculation Formula
Both length and width of belt will be affected by the ambient temperature change, such as belt will extend when temperature increases and contract when temperature decreases; this part should be considered with a deliberate calculation while designing the conveyor system. The calculation formula of dimension variation are as follow.

Example 1：
|
The conveyor belt in P.P. material with the dimension in 18.3m for the length and 3.0m for belt width, start form the operating temperature 21℃. What will be the result of the belt length and width at operating temperature increase up to 45°C ?
|
|
|
TCL = 18.3 × ( 45 - 21 ) × 0.124 = 54.5 ( mm )
TCW = 3 × ( 45 - 21 ) × 0.124 = 8.9 ( mm )
|
|
|
From the calculation result, we know that the length of belt will increase approximately up to 55mm and the width of belt may increase nearly 9 mm under temperature range 21 ~ 45°C.
|
|
|
|
|
Example 2：
|
The conveyor belt in P.E. material with the dimension in 18.3m for the length and 0.8m for belt width, start form the operating temperature 10℃. What will be the result of the belt length and width at operating temperature increase down to -40°C ?
|
|
|
TCL = 18.3 × ( - 40 - 10 ) × 0.231 = - 211.36 ( mm )
TCW = 0.8 × ( - 40 - 10 ) × 0.231 = - 9.24 ( mm )
|
|
|
From the calculation result, we know that the length of belt will reduce approximately 211.36 mm and the width of belt may reduce nearly 9.24mm, under temperature range 10 ~ -40°C.
