● What is the ball screw? So that the movement of objects, generally speaking, the need to have a driving force for the movement, either directly or indirectly through other agencies to convey to the Department of the final movement. For a car Cases in the engine due to the combustion of gasoline so that the piston moving up and down, and then pass through the middle of the final body to turn the wheel so that it occurred in sports. In the world today, on behalf of the machinery, there are a variety of sports organizations device, it can be said is that all have some form of motor conduction agencies. The Company's production of ball screw is to turn sports into a linear motion, or linear motion into rotary movement of the most reasonable. ● THK specialisms ball screw 1, sliding and screw driving torque compared to the vice 1 / 3 As the ball screw shaft and screw the wire between the mother are doing a lot of ball rolling movement, they are able to get higher efficiency of the campaign. In the past Vice compared to the sliding screw-driven torque 1 / 3 of the following, that is, achieve the same results of the exercise of the power required for the use of screw rolling vice 1 / 3. In regard to energy saving help. 2, to ensure high-precision The company's Ball Screws are made in Japan of the world's highest level of machinery and equipment produced consistent, especially in the study cut, the group Equipment to check the process of the factory environment, the temperature and humidity were strictly controlled, as the sound quality management system to enable precision To fully guarantee. 3, micro-feeding may be As the ball screw is the use of ball movement, so start small moment, no sliding movement as the crawl, to guarantee the realization of Precise micro-feed. 4, no backlash, high-rigidity Ball Screws can be added to the pressure, because pressure can be achieved negative axial gap, and higher rigidity (ball screws through to the Add to the pressure on the ball in practice for mechanical devices, such as when the ball due to the repulsion of the wire can enhance the rigidity of the Department of the mother). 5, high-speed feeding may be As the ball screw movement efficient, small fever, and so we can achieve high-speed feed (movement). ● Construction of the ball screw THK's ball screw in the wire part of the mother have a unique structure. Ball by the way the cycle can be divided into ① ② elbow-to-ball-③ -Cover, the company's main product is shown in the chart below-elbow.
	The Company's main products:
		Vice-pipe screw with wire between the mother channel with rotating ball, the ball on the channel have axial load, the ball rolling to do around the screw shaft after the campaign, set to enter the wire inside the home bend in the mouth, and Along the pipe to once again load circulation, so as to carry out unlimited rolling movement. The product THK ball screw is the most abundant species in the popularity of products can be widely used in a variety of purposes.
	BIF-type products, product BNFN ▲ a single wire to the home of the Central Office to screw around on both sides of the phase difference from the two ▲ wire home together through the pads to increase the pressure so as to Axial gap to achieve a negative result (to pressure state), the volume is small but it can eliminate the backlash of the most common form. Through the use of flange The move has been smooth. The bolt-hole for assembly.
	BNF-type products, product DIK ▲ there is only one wire is the mother of the most simple form, through the flange The bolt-hole for assembly.
