By contrasting and analyzing of various take-ups on belt conveyor . This design is mainly about automatic windlass tension station . Its drive part makes up into worm pair and gear driver . Windlass uses worm gear worm driving reel which binds wire rope to pull tight adhesive tape . In the meantime , it adopts the frequency conversion adjusting speed motor to control tensioning force .

通过对带式输送机各种拉紧装置的比较和分析，本设计主要是自动绞车式张紧装置的设计，其传动部分由蜗轮蜗杆传动和一对开式齿轮传动两部分组成，绞车用蜗轮蜗杆传动带动卷筒来缠绕钢丝绳，从而拉紧胶带，同时采用变频调速电机对张紧力进行控制。

A gearing in which each element partially encloses the other is, of course, a double-enveloping worm gearing.
