Description
Technical Field
The utility model relates to a speed reducer field, concretely relates to roller transmission.
Background
Billet rollers are the basic equipment of steel mills and are used to transport shaped billets, profiles and the like. Because the steel has the characteristics of large volume and heavy weight, no other equipment can replace a roller way to convey the steel on a production line, so the requirement on the reliability of the roller is very high, and the steel billet can generate strong impact force on the roller way when the roller runs, and part of the impact force can be transmitted to a speed reducer of a driving part, so that the speed reducer is required to have enough impact resistance and overload resistance. Because the spacing between each roller is limited and the parts on the roller way are many, the requirement on the size of the speed reducer is high. The existing speed reducer has good impact resistance and overload performance and overlarge volume, and is very difficult to mount, including a motor; the speed reducer with small volume can not bear impact load like a modularized speed reducing motor, and the overload performance is not good, so that large-area parking is easily caused, and the production and the conveying of steel billets are seriously influenced.
