Quantity:

The adjustable turning roll by leadscrew in this section is the fundamental of its type. 

Here the word “fundamental” means:

   1) These ranges of products are representative of adjustable turning roller by leadscrew;

   2) All variations of the equipment (structure/ specification) are made on its basis;

   3) These products have the most extensive application.

From above we can see framework of these leadscrew-adjusting stationary roller bed:

   1) Constitutes: One set of HGK adjusting roller bed by leadscrew consists of one set of driving roller bed and

      one follower one;

   2) Form Up: The driving roller bed consists of pedestal, rectangular guideway, leadscrew and its handwheel, 2

      pieces of rollers and its carriage, motor reducer;

   3) Driving and Transmission: With this type of routine adjusting roller bed by leadscrew, there are 2 sets of 

     motor reducer, left and right each. It is cycloidal gear reducer, which in turn drive transmission unit of worm

     gear reducer. Such kind of combination is the most common used type in this series of adjustable turning roll

     by leadscrew;

   4) Adjustment with Leadscrew: When adjusting center distance of the two rollers, turning the handwheel by 

     hand (There is special made electric type, which we will discuss in one of subsequent segments). The 2 sets of

     carriages move along the rectangular guideway synchronously in opposite direction. Which means, for 

    enlarging the distance, the 2 carriages move away from each other; For decreasing the distance, they travel 

    toward each other;

   5) Roller Material: For HGK small rolling bed of adjusted with leadscrew, its rollers can be joint of rubber& 

    metallic ones; For larger equipment, such as 10Ton or higher, very often rollers are full metallic;

   6) Fixation of these stationary roller bed: There are mounting holes in the pedestal of these adjusting roller 

     bed by leadscrew;

   7) Ready-to-made Handling: The small size of light duty portable turning rollers have very compact 

    construction, easy for movement, storage, changing location, and operation;

   8) User-friendly Manipulation: Same as self-adjustable welding rotator, revolving speed, which is welding/ 

    painting/ operating speed of workpiece, adopts with digital managing& displaying technique, intuitive and easy

    to check, reducing operating difficulty of operators. In this sense, it is a kind of efficient welding rotator.
