รายละเอียดทางเทคนิคของโซ่ลำเลียงแบบเจียมเนื้อเจียมตัว

Any time you design different conveyor methods employing compact conveyor chains, the next fundamental problems needs to be happy.
a. Chain stress: The real tensile strength in operation must be considerably lower than the specified strength of your chain.
b. Strength of loaded parts of chain: The real loads utilized to attachments, this kind of as rollers of base chain, top rated rollers, side rollers, etc. in operation should be considerably smaller compared to the power of those elements.
c. Wear life of chain: Lubrication conditions to make certain the wear life of chain has to be fulfilled.
d. Sag adjustment of chain: The sag on the chain must be kept optimum by tension adjusters, take-up products, guides, etc.
e. Some others: Acceptable measures are taken to prevent rail dress in, machine vibration as well as other complications.

การคำนวณความตึงของโซ่
Usually, at first, tentatively figure out the chain size to become applied referring to “Tentative determination of chain size”. Then, get “Theoretical chain tension (T)” (P213) for the tentatively determined chain, and multiply the worth by “Speed coefficient (K)”, to get “Substantial chain stress (Ta)”. For safety, the considerable chain tension has to be reduced than the “maximum allowable tension” stated during the table of dimensions of respective chains. Consequently, the ailment under need to be content.
Security issue of chain stress
Substantial chain stress (Ta) =Theoretical chain tension (T) ×Speed coefficient (K)
Considerable chain stress (Ta) <Maximum allowable stress
If this affliction isn’t content, choose a larger chain by one dimension and re-calculate.
การกำหนดขนาดโซ่เบื้องต้น
qDetermine the mass (fat) per unit length of parts such as chain and attachment ωc (kg/m or kgf/m) assuming that it’s ten percent with the mass (excess weight) of your conveyed object ω1 (kg/m or kgf/m).
ในการอ้างอิงถึงสูตรการคำนวณให้รับ "ความเค้นโซ่เชิงทฤษฎี (T)" (kN หรือ kgf) และ "สัมประสิทธิ์ความเร็ว (K)" และกำหนด "ความเค้นโซ่ที่สำคัญ (Ta)" (kN หรือ kgf)
eIn reference on the table of dimensions of chains,recognize the minimum chain, whose “maximum allowable tension” is increased compared to the “Substantial chain stress (Ta)”, and regard it as “tentatively decided chain”.
ค่าสัมประสิทธิ์การก้าว (K)
The velocity coefficient (K) expresses the severity of operation problem in accordance for the traveling velocity of chain because the condition gets to be severer because the traveling pace of chain gets larger.
คูณ "ความตึงโซ่ตามทฤษฎี (T)" ด้วย "สัมประสิทธิ์ความเร็ว (K)" เพื่อให้ได้ "ความเค้นโซ่ที่สำคัญ (Ta)"
