Abstract
The invention discloses a damper capable of being assembled and disassembled quickly. The damper comprises a damper left cover, a damper right cover and a torsional damper check ring which are arranged from left to right in sequence. At least three cylindrical helical springs which are evenly distributed into a circle are installed in installation cavities correspondingly formed in the damper right cover under pretightening force. Lightening holes are further formed between the installation cavities and a guide shaft. The damper left cover passes the damper right cover to be buckled with the torsional damper check ring. The outer diameter of each cylindrical helical spring is larger than the depth of a cavity body of each installation cavity, so that the cylindrical helical springs can be pressed by the side walls of left cavities and right cavities when the left cavities and the right cavities rotate relative to the installation cavities. Spline teeth are arranged on the right side of the damper right cover to be connected with a gear shifting guide shaft worm wheel, and internal teeth are arranged on the left side of the damper left cover to be engaged with a gear shifting worm-wheel shaft gear. When external teeth of the gear shifting worm-wheel shaft gear are abraded, automatic compensation of gaps caused by abrasion can be achieved, and gapless meshing between the gear shifting worm-wheel shaft gear and a gear shifting rod is achieved.
