Ball Screw and Motor Connector refers to a device that connects two shafts or a shaft and a rotating part, and rotates together in the process of transmitting movement and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection.

Shaft Coupling Motor Drive designed and produced by our own brand WKT, widely used in OPTO field. Shaft Coupling Motor Drive, diameter length is customized, the lead/pitch length is also customized.
Χαρακτηριστικά:
(1) Lead Accuracy Up to Grade C3 C5 C7 and C10 ,screws have been Standardized. C5 on request.
(2) Precision Ground Ball Nut High Precision Ball Nut are interchangeable between ground and rolled screws.
(3) Available to ship separately ball screw and ball nuts can be shipped separated ensure shortest delivery time. The ball nuts are standardized with light preload, also the preload value can be adjusted to zero or heavy.
Shaft Coupling Motor Drive, we make full use of features of Miniature Ball screw manufacture and super compact design actuator can achieved the high precision C3 according to our customers' requirement. The diameter of one of the screw shaft ends must be less than the screw shaft root diameter, otherwise ball nut cannot be installed.
For Application field, Shaft coupling motor drive also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing.Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack.

Shaft Coupling Motor Drive can be divided into two categories: rigid couplings and flexible couplings.
Rigid couplings do not have the ability to buffer and compensate for the relative displacement of the two axes, requiring strict alignment of the two axes, but this type of coupling has simple structure, low manufacturing cost, and assembly and disassembly. , Convenient maintenance, can ensure high neutrality of the two shafts, large transmission torque, and wide application. Commonly used are flange couplings, sleeve couplings and clamp couplings.
Flexible couplings can be divided into flexible couplings without elastic elements and flexible couplings with elastic elements. The former type only has the ability to compensate for the relative displacement of the two axes, but it cannot buffer and reduce vibration. The common ones are slippery. Block couplings, gear couplings, universal couplings and chain couplings, etc.; the latter type contains elastic elements, in addition to the ability to compensate for the relative displacement of the two axes, it also has buffering and damping functions. However, the transmitted torque is limited by the strength of the elastic element, and is generally not as good as the flexible coupling without elastic elements. Commonly used are elastic sleeve pin couplings, elastic pin couplings, plum-shaped couplings, and tire-type couplings. Couplings, serpentine spring couplings and reed couplings, etc.
