Features of double lead screw

introduction：Double lead screw，Also known as double lead worm or variable tooth thickness worm，It is a mechanical transmission element with a special design。Its main characteristics can be summarized from the following aspects：one、Structure design features double thread spiral design：The left and right sides of the same tooth of the double lead screw have different leads，This design allows the pitch or tooth thickness to vary on both sides。This special design can improve transmission efficiency，Enhanced self-locking performance，And allows for backlash adjustment。Archimedes helix distortion：In some applications，The double lead screw is derived from the Archimedes helix worm，The alveolar width gradually narrowed and the tooth shape narrowed
