UniversalJointCross-axischaracteristics

Universal Joint Cross-axis is characterized by the following：
1、High carrying capacity and other types of universal coupling of comparison, the diameter of the rotation under the same conditions, to deliver greater torque, which is subject to strict restrictions on the diameter of rotating mechanical equipment is more important
2、Efficient delivery of up to 98.7-99.9% transmission efficiency for significant energy-saving high-power transmission, power consumption can be reduced 5-15%
3、Smooth transmission, low noise drive for rolling mill can be rolled to improve quality, improve machine performance, improve operator working conditions. General noise30-40db（A）
4、Reasonable structure, the use of safe and reliable, long life
5、Allowable angle, and up to10°-25°
1.Fan used to apply
Universal Joint Cross-axis is mainly applied to rolling machinery, hoisting and conveying machinery and other heavy machinery, connected to the shaft axis of two different grades. SWP rotary diameter 160-640mm, nominal torque for the 16-1250KN.m, type AF axis angle10 °, G-type5 °; SWC rotary diameter 100-620mm, nominal torque for the 1.25-1000KN. m, the axis angle is 15-25 °.

2.Universal Joint connection method
Universal Joint is a high strength bolts and self-locking nut to connect the two ends of the flange on the other mechanical components, the moment is conveyed through the flange end and key of the friction between the flange to pass. SWP connection size and type of the pre-torque bolts according to Figure III and Table III; SWC connection size and type of the pre-bolt torque and Table IV according to the provisions of the four.
Coupling bolt can only be matched with the flange side of Add, universal coupling nut by tightening the flange side, and its mechanical properties in line with the bolt GB3098.1 in 10.9, the mechanical properties of nuts should be in accordance with GB3098 10 provisions in .4.

3.Universal coupling of the use and maintenance of

1, before the installation of universal coupling, the two ends side of washing, checking, etc. I end with keyway, the likelihood and tightening screws, not allowed to loosen;
2, universal coupling is installed, the normal operation of a class, we must check all fastening screws, if found loose, must be provided for tightening torque tightened again, it repeated a number of classes to ensure that they will not become loose;
3, universal coupling sliding surface, cross-head, bearing lubrication, etc. must be guaranteed in general using 2 # industrial lithium based grease or molybdenum disulfide 2 # Ca-fat, the general conditions in the 500 hours of continuous operation under the refueling time, continuous operation 2 months refueling time, if the temperature under the conditions of work must be refueled once a week, filling the screw hole to screw end bearing, the use of high-pressure oil to spill into the gun so far;
4, Universal Joint 3 months of general use and maintenance must be carried out first, such as indentation, etc. discovered the phenomenon of normal wear and tear, should be replaced;
5, in order to extend the life of universal coupling, in the maintenance into to reverse cross-axis 180 °, to achieve the journal by the alternate use of force;
6, to avoid overloading the long-term use and operation of the accident;
7, in operation in the workplace should always observe the universal coupling of the occurrence of abnormal bearing radial swing and the heat of such a phenomenon and found that the importance of timely maintenance of these phenomena;
8, may be due to the operation of the universal coupling of person and equipment caused by accident all establishments will be required to adopt appropriate security measures.
