1.Our main products Parameter:

Specifications

1. Strength conditions:
Where: -------- clamping force (N)
-------- Gelin diameter (cm)
Z ----------- Gelin root number
--------- Using a tensile stress, N /, taking 7500 ~ 9000N /

2. Fatigue strength conditions:
Where: -------- lasting tensile strength limit (N /)
-------- Material yield limit (N /)
------ Tensile stress generated by the clamping force (N /)
-------- Compressive stress produced by mold force (N /)
--------- Overload when the maximum tensile stress (N /)
n -------- strength safety factor of n = 1.5 ~ 1.8
-------- Stress concentration factor = 1.8 to 2.0
--------- Scaling factor coefficient, Gelin diameter less than 100mm take 1 to 1.1, when more than 100mm take 1.25.

3. Thread strength check:
. i compressive stress:
. ii shear stress:
. iii bending stress:
Where: -------- maximum load force by the first thread on the clamping force is calculated by 14%
--------- Thread form factor, trapezoidal thread = 0.63 to 0.68
S ---------- trapezoidal thread pitch
