Introduction to the fixing method of plum coupling

Plum couplingThe main parameters of the medium MR plum blossom elastic coupling:
　　a. Elastic torque can absorb vibration and compensate for radial and angular deviations.
　　b. Oil resistance and electrical insulation, the main body adopts anode surface treatment.
　　c. A variety of elastomers with different hardness (yellow/red) are available for selection.
　　d. Maintenance-free, convenient for visual inspection.
　　e. The characteristics of clockwise and counterclockwise rotation are the same.
MR type plum blossom flexible coupling scope of application: suitable for reducer, servo motor, machine tool spindle, packaging machinery, printing machinery and other applications.
Common fixing methods of plum coupling:
　　(XNUMX) The quincunx coupling positioning type is the traditional fixing method:
　　　1. The damage to the shaft caused by this fixing method is relatively large: because the fixed positioning bolt has a relatively small stress point, the friction force generated between the fixing bolt and the connecting shaft will cause the unbalanced force to cause extra deviation.This fixing method is limited to fixing the small shaft.
　　　2. The fixed positioning couplings currently seen in the market are mainly composed of two positioning bolts.
　　(Two), plum blossom type coupling clamping type and expansion sleeve fixed
　　　1. This fixing method is a new fixing method due to the lack of fixing bolt fixing type.
　　　2. Because of the relatively high production cost of these two fixing methods, their selling price is also relatively high.
　　　3. Clamping type and expansion sleeve type are more troublesome in installation than positioning type, but these two fixing methods can make up for the lack of positioning screw fixation.
Since there are 2 fixing methods, it is very convenient in application.
