Worm Gear Screw Jacks---Lude Transmission

The   worm gear screw jacks   we see are usually   screw jack s with single start lifting screw .   Here start means the thread cut on the screw. Please see below picture. Often a screw jack is required not to 'back-drive' when the holding force is removed and an axial load is applied. A single start thread is commonly used in these situations as the shallower helix angle causes greater friction between threads and is usually sufficient to prevent slippage. Such a system is said to be self-locking. This assumes a statically loaded system with little or no vibration as this may cause the friction angle to be overcome and the combination to untighten. In systems that are subject to vibration a locking mechanism or brake is advised to prevent back-drive. If self-locking is not a requirement of a system but a greater speed of translation is needed, then a multi start thread may be used. This implies that multiple thread forms are created on the screw shaft. Doub...

  Worm screw lift s   have the features of low-cost , easy  install ation , flexible use, so they are used by more and more industries. Screw lifter ’ s worm gear drive has a good self-locking function,  it  can maintain the load    even without braking device .   Worm gear drive makes the worm wheel rotate. The trapezoidal thread in the worm gear cooperates with the screw rod to drive the screw rod to rotate axially ,then   realize the deceleration and lifting functions.          Several Screw lift s  can make up a screw jack platform , driven by a motor or hand wheel with other components to complete the synchronization of smooth movements. It should be noted that the screw lift platform, whether it is two, four or more linkage ,it is recommended to choose one motor when we choose the drive.    B ecause different motor s ’  speed has  speed difference, it is difficult to ...
