The structural features and application of the cross shaft universal coupling:
     The cross shaft universal coupling get a wide range of applications because of high transmission efficiency, allows two-axis angular displacement, lower noise and lubrication requirements, work reliability. According to the structure is divided into: Integral fork head - UC and split fork - UP two series structure--UP.
1. The major features of the cross shaft universal coupling:
1.1 Ability to compensate a large angle. UC Series axis angle can reach 15 ° to 25 °. UP series can reach 10 °.
1.2 Large bearing capacity. Compared to other types of couplings with same swing diameter, the greater torque transmitted for the turning diameter limited mechanical equipment, which its matching range has more advantages
1.3 High transmission efficiency. The transmission efficiency of 98% to 99.8% for high-power transmission, energy-saving effect is obvious.
1.4. Smooth operation, low noise, easy assembly, disassembly and easy maintenance
Structural style of cross shaft universal coupling
1. UC Series
UC series because of the cross shaft bearing fixed to prevent loose bolts or broken, thus increasing the strength of the weak links, improve the service life, and is easy to repair. UC series apply to different needs. There are seven kinds of structure:
Structure nameStructure code
Standard telescopic weldedB
Standard telescopic flangeF
Short telescopic welded
Long telescopic welded
Non-stretch welded
No telescopic flange
No stretch shortening

2. UP Series
The UP is considering the bearing of universal coupling is quick-wear part, the gland is made split, is to facilitate the replacement of bearings.
UP series apply to different needs. There are eleven kinds of structure:
Structure nameStructure code
flexible long telescopic
Flexible short telescopic
Nonflexible short telescopicY
Nonflexible long telescopicW
Double flanged long telescopic
Large long telescopic
Flexible ultrashort telescopic
shaft sleeve and fork installed through-typeGA
shaft sleeve and fork anti-installed through-type GB
shaft sleeve anti-installed and fork installed through-typeGC
shaft sleeve installed and fork anti-installed through-typeGD
Selection of cross shaft universal coupling
   When select and use the cross shaft universal coupling, according to the basic information and calculate the torque, preliminary select the Coupling Model Specification. Then from standard found the corresponding specifications corresponding to the maximum pore size, the maximum radial dimension (Rotary space) and the allowable speed can meet couplings working conditions to determine the selection and use of cross universal coupling model specifications.
1. According to the following steps to select and use couplings
2. 1.1Selection and use of the basic information
3. Drive machine names, drive machine quantity, input power, working speed, work machine name, load type, working environment, nature of work, whether frequent start, whether positive & negative, input and output shaft diameter and length.
      Basic information see table 1.
1.2 Selection and calculation
      The main parameter of the coupling is the nominal torque Tn, among various torque when selection should accord with the following relationship:
In the formula: T Theory of torque, N. m
       Tc-computed torque, N·m;
       Tn-Nominal torque, N·m;
        [T] -Allowable torque, N·m;
       [Tmax] -allowable maximum torque, N·m;
        Tmax -maximum torque, N·m;
1.2.1 Couplings theories torque calculation
        In the formula: Pw-driving power; Kw
n - working speed, r/min
1.2.2 The torque calculation of  coupling
calculation formula Tc=T·Kw·K·Kz
 In the formula: Kw -Coefficient of engine (see table 1)
                      K -working condition coefficient (see table 1)
Kz -Start coefficient (see table 1)
