We could provide SWC coupling for port facilities and harbor machinery project which is ZPMC spare parts.
Type SWC & SWP Universal Couplings can be used to transmit torque in metallurgy, hoisting, engineering transportation, mining, petroleum, ship, coal industry, rubber, paper making machines and heavy machinery industry. They are suitable for heavy machinery shafting trans-mission.
The major characteristics of Series SWC & SWP Universal Couplings
1.Relative big angular compensation ability. Permissible axis angle for SWC type is between 15 and 25 The permissible axis angle for SWP is about 10
2.Compact and reasonable configuration. The integral fork adopted on SWC type makes operation reliable.
3.high load capability. Compared with other types of couplings with the same rotatable diameter, it can transmit higher torque and have more suitability for machines and equipment whose rotatable diameters are limited.
4.High transmission efficiency, reaching 98-99.8%. It saves much energy during transmitting high power.
5.Stable operating, low noise, convenient maintenance and easy assemble and disassemble.
Installation and Maintenance
For SWC type and SWP type of universal couplings, Rational use and regular maintenance are very important for transmission performance and service life. The users should pay attention to the following points:
A.Before installation, the joints and surface of flange should be cleaned. It is necessary to check if the connection surface is leveled up and good condition, otherwise, should be adjusted.
B.Please check the fork’s position and arrow mark. Please make sure the fork of splined shaft and hub are in the same phase.
C.During installation, do not rotate universal joint by using lever, otherwise it will damage bearing sealed part.
D.Insert bolt into the hole of jointed equipment’s flange and then tighten nut from the side of universal coupling. If the space is limited, users can consider using stud.
E.Before installation, users should check tension level of bolt and nut to make sure them conform to the standard. ( 10.9 grade for bolt and 10 grade for nut )
F.During installation, users should align the mating mark of flange and then tighten bolt and nut by using torque wrench symmetrically and uniformly. We suggest apply a drop of oil into screw holes. Tension relationship is in table 17.
G.After coupling has run with load for a shift or two, please check the bolts and nuts to make sure they are not loose. If loose, please tighten them according to standard force moment. This should be repeated after another two shifts.
H.If the coupling is working in high temperature condition, oil it every one or two weeks. In general condition, oil the coupling every three months. We recommend No.2 lithium base grease.
I.In general condition, the coupling should be checked regularly. Especially if the coupling is working in key condition or working constantly for long time without stop, it must be checked regularly. J.After maintenance, follow assemble instructions in reverse to disassemble and make sure the position are the same as before according to the marks. Make sure the fork of splinted shaft and the hub are in the same phase. There should be 0.1~0.3mm axial clearance beside Spider. The connecting bolt should be tighten by using torque wrench according to Table 17. After assemble, please lubricate bearing and splinted shaft.
