Haida Rally testing machine screw upgrade again

With the advancement of science and technology , the instrumentation industry is innovating , and the tension machine configuration has been developing Haida as a tensile machine, universal material testing machine, tensile testing machine and other instrument manufacturers, and has always been consistent with the dynamics of the industry , and strive to innovate the Rally machine. Aspect configuration. Today , our Rally screw is also replaced by a ball screw. The advantages of using a ball screw in a pulling machine include the following:

   1 , no backlash, high rigidity

   Ball screw can be added to the pressure , because the preload can make the axial gap to a negative value , and then get a higher rigidity.

   2 , can achieve high-speed transmission

   The ball screw can realize high-speed transmission due to high movement efficiency and low heat generation.

   3 , high accuracy

   The ball screw ball movement, a small starting torque, will not be sliding sports such as crawling phenomenon, to accurate micro feed.

   4 , long service life

   Rolling friction has a small surface damage , so when the conditions of cleaning, lubrication and the like are met , the ball screw has a high maintenance life.

   5 , no self-locking

   Usually self-locking and transmission efficiency is inversely proportional to, the higher the transmission efficiency, the smaller the self-locking, therefore, almost no self-locking screw.

   6 , high efficiency , energy conservation

   Since there are many rolling balls between the screw shaft of the ball screw pair and the screw nut , the movement efficiency is high.
