Henan Honglin Transmission Technology Co., Ltd. (formerly known as Henan Honglin Universal Transmission Co., Ltd.) was established in 2017 and is located in Xinxiang City, Henan Province. It is a professional enterprise that researches, develops, produces, and sells universal shaft couplings.

The structural forms of universal couplings include cross shaft type, ball cage type, ball fork type, convex block type, ball pin type, ball joint type, ball joint plunger type, three pin type, three fork rod type, three ball pin type, hinge rod type, etc. The commonly used ones are cross shaft type, followed by ball cage dragon. In practical applications, they are divided into heavy, medium, light, and small according to the transmitted torque size.

The universal joint utilizes the characteristics of its mechanism to enable the two shafts to rotate continuously and reliably transmit torque and motion when they are not on the same axis and there is an angle between the axes. The biggest feature of a universal joint is that its structure has a large angular compensation ability, a compact structure, and high transmission efficiency. The angle between the two axes of different structural types of universal couplings is not the same, generally between 5 ° -45 °.

A mechanical component used to connect two shafts (the driving shaft and the driven shaft) in different mechanisms to rotate together and transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, vibration reduction, and improving the dynamic performance of the shaft system. The coupling consists of two halves, which are respectively connected to the driving shaft and the driven shaft. Most power machines are connected to the working machine through couplings. [1]

National standard specifications

The cross shaft universal joint is a widely used universal joint, and the bearing is a vulnerable part of the cross shaft universal joint. The main difference between several large cross shaft universal couplings lies in the changes in the bearing seat and cross head, forming different structural forms. To ensure the synchronization of the main and driven shafts, a double connection form is adopted in practical applications. The double connection method is nothing more than welding or flange plate connection through bolts, and there can be various forms of changes in the length of the middle. The cross head components of the cross shaft universal joint have the following forms: SWC type integral cross head cross shaft universal joint (JB/T 5513-2006), SWP type partial bearing seat cross shaft universal joint (JB/T 3241-2005), SWZ type integral bearing seat cross shaft universal joint (JB/T 3242-1993), WS type small double cross shaft universal joint (JB/T 5901-1991), WSD type small single cross shaft universal joint (JB/T 5901-1991), cross package for SWP type cross shaft universal joint (JB/T 7341.1-2005), and cross package for WGC type cross shaft universal joint. JB/T 7341.2-2006). The above heavy-duty and small-sized cross shaft universal couplings are universal types, and different models in the automotive industry have their own dedicated cross shaft universal couplings or other types of universal couplings. For example, sedans use ball cage universal couplings. In addition, agricultural machinery, industrial machinery and other sports machinery products also have dedicated universal couplings, and most of them use cross shaft universal couplings.
