Cross 5-280X PRECISION 334 universal joint is a type of unequal velocity universal joint, that is, when the angle between the two shafts connected by the universal joint is greater than zero, the output shaft and the book input shaft transmit motion at a varying instantaneous angular velocity ratio, but the average angular velocity equal.

Mainly refers to the single cross shaft universal joint:

1. When the driving fork plane is in the vertical position and the cross shaft plane is perpendicular to the driving shaft axis, the speed of the driven shaft is greater than that of the driving shaft.
2. When the driving fork plane is in the horizontal position and the cross shaft plane is perpendicular to the axis of the driven shaft, the speed of the driven shaft is less than that of the driving shaft.

From the analysis of the above two special cases, it can be seen that in the transmission process of the cross-shaft universal joint, the rotation speed of the main and the driven shafts are not equal.

The so-called "uneven speed of transmission" refers to the uneven angular velocity during the rotation of the driven shaft. In short, the advantages are safety, simple structure, convenient use and maintenance, and low cost. The disadvantages are that the technology is low, the price is too cheap, there are too many counterfeit goods in the market, and the raw material waste of U-Joint With Brackets Tapered Kits is large.
