Abstract
The invention discloses a cylindrical gear column, which comprises a cylindrical gear column and a sleeve-shaped gear column. The cylindrical gear column comprises a cylinder body and a gear arranged at the outer side of the cylinder body; one side of the cylinder body is provided with a circular chassis; the cylinder body, the gear and the circular chassis are of an integral structure. The sleeve-shaped gear column comprises a cylindrical casing and a sleeve gear at the outer side of the cylindrical casing; the sleeve gear is provided with a chamfer; the cylindrical casing and the gear are of the integral structure; the cylindrical gear column and the sleeve-shaped gear column are fixedly matched. The cylindrical gear column disclosed by the invention is formed by fixedly matching the cylindrical gear column and the sleeve-shaped gear column, so that the cylindrical gear column can be stably fixed and is convenient to disassemble. The cylindrical gear column and the sleeve-shaped gear column are of a powder metallurgy one-time forming structure, so that the cylindrical gear column is high in mechanical strength and long in service, and abrasion-resistant.
