5-7126X 6H2577 universal joint is a kind of universal joint. Rigid universal joints can be divided into non-constant velocity universal joints (commonly used as cross shaft type), quasi-constant velocity universal joints (such as double joints), and constant velocity universal joints (such as ball cage universal joints). Section) Three kinds.

The cross-shaft rigid universal joint has the advantages of simple structure and high transmission efficiency. However, when the angle α between the two shafts is not zero, the constant angular velocity rotation cannot be transmitted.

In the transmission process of the cross-shaft universal joint, the rotation speed of the driving and driven shafts are not equal. The so-called "non-uniform 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 materials are wasted.

The advantages of cross universal joints are simple structure, reliable transmission, and high efficiency. 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.
