4 Sungil icro Coupling icro Coupling Alignment Adjustment 1 Flexible coupling can transmit torque and rotation angle while allowing misalignment. When the misalignment gets higher than limit, vibration may occur and the life of coupling may be reduced. ake sure to adjust the alignment accordingly 2 There are three types of shaft misalignments such as eccentricity (error in parallel alignment), angularity (error in angular alignment) and end-play (shift axle direction). Adjust the alignment to be lower than limit listed in the specification table of each product provided in this catalog. 3 The limit of misalignment recorded in this catalog is for one misalignment for eccentricity, angularity and end-play. When there are more than 2 misalignments, we recommend you to apply 1/2 of misalignment limit 4 isalignments are sometimes caused not only by equipment assembly but also by vibration, heat expansion, wear of bearings and so forth during operation. Therefore, it is recommended to adjust the shaft misalignment to be below 1/3 of maximum limit. Parallel Offset isalignment Combined Angular-Offset isalignment Symmetrical Angular isalignment End-Play Non-Symmetrical Angular isalignment Run Out Adjustment of according to Temperature SOH, SFC, SJC, SGF use polyurethane, polyacetal or plastic parts or Anti- Vibration Rubber. These models must be used in the operational temperature indicated in this catalog. When ambient temperaure exceeds 3, maximum torque and rated torque should be checked by the correction value chart beside. Category Temperature Correction Value -2 ~ ~ ~ ~ 1.5 Cautions isalignment exceeding maximum limit and excessive torque may result in shorter life of coupling due to plastic deformation. Stop machine operation at once when there is abnormal metallic noise, and proceed to check shaft misalignment, disturbance in shaft rotation, loosen screw and so forth When used at rotation machine with significant load fluctuation, apply adhesive on screw to prevent loosening or select a size on higher rank. ax is thing that can transfer torque momentarily. Rated is thing that can transfer torque continuously. 4 SUNGI ACHINERY

Ideal-Realization of Servo System New developed flexible disk coupling realized the servo system perfectly by securing the flexibility and increase the number of mounting hole and maximizing the mobility space of sus disk plate. We consider each component most carefully and make the disk together with bush by one package in order to long life time of disk. The outside diameter size of bush is bigger than outside diameter size of hole and disk shape is similar with shape of R. so this product has durability about big torsion because of these features. New flexible disk coupling is constructed by package of some sus disk and bush. This product is protected from load and the form of disk is not changed by making into one package. We assemble new flexible disk coupling perfectly. We measure and adjust concentricity every process so new flexible disk coupling of SI is assembled completely by adjusting concentricity perfectly.

29 SJC Series Zero acklash Jaw Coupling Selection ethod Therefore, SJC Series coupling can be divided into 2 purposes of zero backlash method to deliver rotation angle and method to deliver torque mainly. Since each sleeve with different hardness has different characteristic, select appropriate coupling. 1. ain purpose is to deliver zero backlash When using coupling in low torque range in order to deliver rotation angle, same zero backlash characteristic that metal spring coupling offers can be used. In addition, it has the function of absorbing torsion vibration that common coupling cannot offer. When it is used for zero backlash, rotation transfer torque becomes less than the torque listed in the table. Please refer to the table below. Even though torque limit for zero backlash torque is same in 2 sleeves, a sleeve with higher hardness can get higher performance concerning the necessary responsiveness to deliver rotation angle accurately. 2. ain purpose to deliver torque SJC type coupling can be used for higher torque than metal coupling in that it delivers torque by contracting the sleeve. Therefore, it can be applied to general industrial machine such as pump that does not need zero backlash. Even though SJC couplings are standardized in different sleeves, green sleeve with lower hardness has lower usual torque and maximum torque while red sleeve with higher hardness has higher usual torque and maximum torque. On the contrary, misalignment limit is large in green sleeve and smaller in red sleeve. Please, select proper sleeve for use.
