The Classification of Screw Drive

   Screw drive, the use of the screw and nut engagement to transmit power and motion of the mechanical drive. Mainly used to convert rotary motion into linear motion, the torque is converted into thrust.
   Classification
   By job characteristics, screw drive with a helical spiral into force transmission, conduction and adjustment screw spiral.

Ball Screw Support Set

  1.Force transmission screw: to transmit power based, which have a greater torque with a small axial thrust, usually intermittent, the working speed is not high, and usually requires from the lock, such as screw presses and screw jacks spiral.
  2.Conduction spiral: to transmit motion-based, often requires a high precision of movement, usually over an extended period of continuous work, the working speed is higher, such as the machine feed screw.
   3.The set screw: for adjusting and fixing parts or the relative position between the components, generally do not always turn, requires self-locking, and sometimes also requires very high accuracy, and precision instruments such as machine screw fine-adjustment mechanism. According to the nature of friction between the threads, screw drive can be divided into sliding screw drive and rolling screw drive. Sliding screw drive can be divided into ordinary spiral sliding screw drive and hydrostatic drive.
