WX stainless steel double joint drive shaft coupling for boat

The universal joint, in the begining means of transmitting power between two shafts, was invented by Gerolamo Cardano in the 16th century. The fact that it failed to maintain constant velocity during rotation, later was reconized by Robert Hooke in the 17th century,he invented the first constant velocity joint, consisting of two Cardan joints offset by 90 degrees, so as to cancel out the velocity variations. This is the "double Cardan joint ". Many different types of constant-velocity joints have been invented since then.
such as the small precision universal joint ,the fast release and lock universal joint,even with the function of telecopic ,we call it telescopic universal joint

Product Description

Structure feature:

1. It is suitable for the transmission with the axis angle β<45°of the two axis on the same plane

2. 11.2-1120N.m : nominal torque 11.2-1120N.m

3. Maximum bending angle 45° per joint.

4. Finished product hole tolerance H7, keyway, hexagonal hole and square hole can order as requirement .

5. Angle between the two axes can change with the machines needs within a limited range.

6. sliding bearings and needle bearings both acceptable, it’s depending on user requirements. The maximum speed with sliding bearing is 1000rpm, the dynamic load with  needle bearing is higher, the bearing clearance is small, and the maximum speed can reach 4000rpm.

Installation and Selection:

To ensure angular velocity of rotational motion between the driving and driven shaft under synchronous rotation,should choose double cross shaft universal joint or two single cross shaft universal joint connect together ,also need meet the following 3 conditions :a)the angle of intermediate shaft between driving and driven shaft should equal ,b)The symmetry surfaces of the two ends of the intermediate shaft are in the same plane ,c)When the intermediate shaft and the driven shaft in the same plane to install the single shaft universal joint, the angle of driving and driven is different ,can not keep synchronous operation,will change with the angle .
