Product details:

The HL nylon rod pin coupler is a cylindrical pin with a flexible sleeve (nylon rod) on one end, which is mounted in the flange hole of the two-part coupler to realize the coupling of the two-and-a-half coupling. Elastic dowel pin shaft coupling was once the coupling of the most widely used in our country, as early as the late 1950 s, which is for the mechanical standards, JB08-60 elastic dowel pin coupling, is China's first standard coupling.

Nylon rods HL dowel pin coupling structure is simple, manufacture easily, no lubrication, don't need and metal sulfide, change the elastic sleeve is convenient, need not move half coupling, two axis relative offset compensation and vibration damping buffer performance. Elastic sleeve work is subject to compression deformation, due to the thickness of the elastic sleeve thin, small size, elastic deformation is limited, so, although elastic dowel pin shaft coupling can compensate the axis displacement and flexibility, but axis allowable displacement compensation quantity is less, less elastic. The elastic pin coupling is based on the locking force of the column pin group to produce the friction torque on the contact surface, and compresses the elastic sleeve to transfer torque. It is suitable for small and medium power shafts with high rigidity, high accuracy, low impact load and low demand for vibration reduction.

Nylon rods HL dowel pin coupling transmission torque value should be less than the allowable torque, maximum torque machine should be considered to determine the braking deceleration torque and overload torque required, but insufficient information or analysis problem, when the design, the maximum torque are difficult to determine could be selected according to the calculated torque. That does not exceed the allowable torque value.

Calculate torque Tc: use the following formula

Tc = KT

T = 9550 x Pw/PH/n n = 7020 x

T = theoretical torque N.m

K - working conditions coefficient, can be referenced by JB/zq4383-86 "couplings load classification and working conditions coefficient", usually 1? K? 5.

Pw - drive power, Kw

PH - drive power, horsepower

N - RPM, RPM
