Whether linear stepper motor or other types of stepper motor, coupling are they necessary accessories, is also the main components, its main role is in the stepper motor drive, ACTS as a hub for the role, in particular is used for connecting a stepper motor shaft and driven shaft, so as to transfer torque, which requires the coupling must have precision turning performance, if the rotation performance comparison slow will greatly reduce the working efficiency of the stepper motor. At the same time, its rotation has asked its has four advantages: 1, zero clearance: coupling overall in the process of transmission is not allowed to have clearance; 2, high rigidity, coupling not allowed transmission delay, otherwise will seriously affect the accuracy of stepper motor drive; 3, low inertia: on the basis of transmission intensity, should as far as possible to reduce the weight of the stepper motor coupling; 4, good flexible: precision stepper motor coupling, not only requires high rigidity, at the same time need to correct the installation process to produce all kinds of deviation between the driving shaft and driven shaft. Here are the commonly used three kinds of stepper motor coupling characteristics as simple introduction, for reference in the design, type selection. A, 1, the plum blossom plum coupling coupling are highly flexible and rigid at the same time, according to the requirements can choose different hardness of the elastomer; 2, zero clearance transmission, the plum blossom between elastomer and metal sleeve has a great deal of pressure force, ensure stick tightly between phase; 3, clamping structure is used to shaft hole, in order to ensure no clearance between shaft and hole; 4, polyurethane elastic body connection between, excellent electrical insulation properties; 5, use the temperature -Between 20 ℃ ~ 60 ℃. 2, 1, diaphragm coupling, diaphragm coupling points single diaphragm structure and double diaphragm structure, the double diaphragm more flexible; 2, relative to other forms of stepper motor coupling, rigid higher; 3, has good heat insulation performance; 4, the shaft hole form points clamping type and locking type two kinds, including expansion sleeve can bear big moment of inertia, commonly used in CNC machine tools (Machining center)Main shaft coupling. Three, elastic coupling type 1, which slit cutting metal elastic coupling; 2, the permissible eccentric, Angle and axial deviation; 3, high torque stiffness sensitivity and excellence; Four, exactly the same clockwise and anticlockwise rotation characteristics; 5, stainless couplings can cope with bad environment. In design not only motor or stepper motor, the choose and buy all need comprehensive consideration to the three types of characteristics, in order to choose more appropriate accessories.
