The following points can be considered in the specific selection: Most 5-280X PRECISION 334 universal joint couplings have been standardized or standardized. The designer's task is to choose, not design.

The basic step of selecting universal joint coupling is to select the type of universal joint coupling. According to the size of the transmitted load, the speed of the shaft, the installation accuracy of the two parts being connected, etc., refer to the characteristics of various universal joint couplings. , Select a suitable universal joint coupling type.

1. The size and nature of the torque to be transmitted and the requirements for the buffer and vibration reduction function.

For example, for high-power and heavy-duty transmissions, gear universal joint couplings can be used; for transmissions that require severe impact loads or that require the elimination of shaft torsional vibrations, tire-type universal joint couplings can be used with high elasticity. Universal joint coupling.

2. The working speed of the universal joint coupling and the centrifugal force caused by it.

For high-speed transmission shafts, universal joint couplings with high balance accuracy should be selected, such as diaphragm universal joint couplings, etc., instead of eccentric slider universal joint couplings.

3. The magnitude and direction of the relative displacement of the two axes.

When it is difficult to maintain strict and precise alignment of the two shafts after installation and adjustment, or when the two shafts will have a large additional relative displacement during the working process, a flexible universal joint coupling should be used. For example, when the radial displacement is large, the universal joint coupling of the slider can be selected, and the universal coupling can be selected for the connection of the large angular displacement or the intersecting two shafts.

4. The reliability and working environment of the universal joint coupling.

Universal joint couplings usually made of metal components that do not require lubrication are more reliable; universal joint couplings that require lubrication are easily affected by the degree of lubrication and may pollute the environment. Universal joint couplings containing non-metallic components such as rubber are more sensitive to temperature, corrosive media and strong light, and are prone to aging.

Due to reasons such as manufacturing, installation, load deformation and temperature changes, it is difficult to maintain strict and precise alignment of the two shafts after installation and adjustment. There is a certain degree of displacement in the x and Y directions and the deflection angle CI. When the radial displacement is large, the sliding block universal joint coupling can be selected, and the universal joint universal joint coupling can be selected for the connection of large angular displacement or intersecting two shafts. When the two shafts produce a large additional relative displacement during the working process, a flexible U-Joint With Brackets Tapered Kits coupling should be selected.
