Linear slide stage adopts precision rail, with precision ball screw, do servo drive, and the transmission element is ball screw, it has a variety of structures. Its classification can be divided into two categories: external circulation and internal circulation. The following is a linear slide table manufacturer PDV to introduce the six major reasons for the selection of ball screw linear slide stage.
Features of linear sliding stage ball screw:
1. Compared with the sliding rod pair, the linear sliding stage has a driving torque of 1/3 ball screw. There are a lot of rolling wires in motion between the screw shaft and the screw shaft, so it can get higher motion efficiency. Compared with the slider screw pair in the past, it is also very helpful in saving electricity.
2. The ball screw is produced coherently, especially in the grinding, assembly and inspection of the factory environment of each process, the temperature is strictly controlled, because of the perfect and exquisite management system is to ensure the accuracy.
3. The micro-feeding of linear sliding table may make use of ball screw, so the driving force is very small, and there will be no crawling phenomenon like sliding motion, which can ensure the accuracy.
4. Linear sliding table without backlash, rigid good ball screw can add pressure can use axial clearance to achieve negative value, and then get higher rigidity (ball screw by adding pressure to the ball, in actual mechanical devices, due to the crack force of the ball screw can use the screw rigidity enhancement).
5. The high-speed feed bearing of linear sliding table may be pneumatic ball screw of linear sliding table because of high dynamic efficiency and small heating, so high-speed feed (movement) can be realized. Accuracy tolerance: C7, C6, C6, C3, 2, C1-- The smaller the number, the higher the accuracy.
6. Linear sliding stage fixed screw, rotating nut. Due to the static of the lead screw, it avoids the boundary and influence of high speed and low speed movement of the lead screw, and the nut can achieve higher speed because of its small volume and high sensitivity. It can increase the prepressure and compensate the thermal deformation.
PDV production of ball screw linear slide sets of high sensitivity, large carrying capacity, can meet the different needs of customers, our company operating a variety of optical displacement machine, manual translation units, electric lift platform, rotating platform, Angle, and microscope, etc. Various kinds of laboratory instruments and equipment, can provide customers with faster, more professional, more perfect technical support and after-sales service.
