According to 5-153X GU1000 PRECISION 369 universal joint is a kind of universal joint. Whether the universal joint has obvious elasticity in the torsion direction can be divided into the rigid universal joint and flexible universal joint.
When the following two conditions are met, a constant angular speed transmission from the output shaft of the transmission to the input shaft of the drive axle can be realized:
1) The universal joint forks at both ends of the driveshaft are in the same plane;
2) The angle α1 between the two shafts of the first universal joint is equal to the angle α2 between the two shafts of the second universal joint.
Because when driving, the drive axle has to jump relative to the transmission, it is impossible to have α1=α2 at any time. In fact, it can only achieve approximately constant speed transmission from the transmission to the drive axle.
In the above transmission device, the greater the angle of intersection α between the shafts, the more uneven the rotation of the transmission shaft, the greater the additional alternating load generated, the more unfavorable the service life of the parts, and the reduction of transmission efficiency, so in the overall arrangement, The angle of intersection between these axes should be minimized.
