Product details
First, scope of application:
SWC medium-sized universal coupling is mainly applied to the mechanical use occasions such as steel rolling mill, piercing machine, straightening machine, crusher and ship drive, which is a widely used universal shaft product series.
Its flange diameter is 160-620mm, transmitting rated torque range 16-1000kN.m, and the axis folding angle is 15°.
Second, the structure characteristics:
1, universal coupling using its institutional characteristics, so that the two axes are not in the same axis, the existence of axial angle can be realized in the case of the two axes coupled to continuous rotation, and reliably transfer torque and motion.
2, medium-sized universal coupling is characterized by: a compact structure, transmission torque, long service life, can be used for a long time in poor working conditions and other advantages.
Third, selection and maintenance:
According to JB5513-91 standard, SWC-I and SWC type universal coupling refer to the following method of selection:
Calculated torque is derived from equation (1), equation (2) or equation (1), equation (3):
Weicheng universal shaft torque calculation formula
1) Where: Tc – calculated torque, N-m;
T – theoretical torque, N-m;
Pw – drive power, kW;
PH – driving power, hp;
n – working speed, r/min;
K – working condition coefficient
2) Work situation coefficient K
| Nature of the load | Name of the equipment using the cardan shaft | K |
| Light shock load | Generator/ centrifugal pump / ventilator / woodworking machine / belt conveyor | 1.1-1.3 |
| Medium shock load | Compressor (multi-cylinder) / piston pump (multi-cylinder) / small section mill / continuous wire rod mill / conveyor main drive | 1.3-1.8 |
| Heavy impact load | Paper machine/ship drive/transport roller conveyor/continuous tube mill/continuous work roller conveyor/medium section mill/compressor (single cylinder) piston pump (single cylinder)/mixer/press/straightener/crane main drive/ball mill | 2-3 |
| Extra heavy impact load | Crane auxiliary drive/crusher/reversible working roller conveyor/coiler/phosphorus breaker/primary mill | 3-5 |
| Extremely heavy impact load | Mill feed roller conveyor/thick plate shear | 6-15 |
Note:
1. In general, according to the transfer of torque and bearing life selection of universal coupling, but also according to the specific requirements of the use of machinery and equipment, only check the torsional strength or bearing life of one;
2. When the coupling in the horizontal and vertical plane at the same time exists between the axis of the folding angle, should also calculate its synthetic axis of the folding angle;
3. Part of the special use of environmental conditions, universal coupling in the selection stage to consider the use of speed and dynamic balancing requirements;
4. Cross shaft type universal coupling should be selected according to the load characteristics, calculated torque, bearing life and working speed and other related factors.
We manufacturer provides one-stop service of medium-sized universal shaft selection, universal shaft parameter design, research and development, and universal shaft production, universal shaft manufacturer direct supply, so that you save time, effort and worry.
At the same time to provide SWC medium universal coupling transportation and storage, installation and use, maintenance and repair of technical guidance.
Note:
1. The meaning of each code in the above table is as follows:
L – standard length, for the retractable type, the length L is the minimum length in the shortened state;
Lv – elongation;
m–Mass;
Tn – nominal torque (take 50% of the yielding torque);
Tf–Fatigue torque, i.e. the permissible torque determined by fatigue strength under variable bending load;
β – the maximum axis folding angle;
mL – the mass of the growth of 100mm.
- The above table does not specify the unit of measurement according to millimeters;
- When users need to change the standard length, expansion and flange type size, please set with our manufacturer.
