Compost trommel screen roller assembly structure belongs to the field of screening machinery. To solve the compost trommel screen drum welding stress concentration welding change.
The question of form. Including a cylinder and a rolling ring for a compost trommel screen, characterized by the rolling ring being welded to the cylinder by means of a connecting plate; The connecting plate is a butterfly connecting plate with one end narrow and the other end wide. The two ends of the butterfly connecting plate are processed with plug welding holes; The butterfly connecting plate is arranged successively in the gap between the rolling ring and the barrel, the narrow end is welded together with the rolling ring, the wide end is welded together with the barrel, and the welding position is in the edge of the butterfly connecting plate and the plug welding hole. A wear-resistant rubber layer is arranged on the outer surface of the rolling ring. Featuring strong welding, stress dispersion, small deformation and high efficiency, it is suitable for compost trommel screens of all sizes.
compost trommel screen consists of a cylinder, a rolling ring, a support wheel and a driving device. The driving wheel drives the rolling ring and the cylinder to rotate the material. compost trommel screen is generally installed with inclination Angle, so the compost trommel screen rolling ring in the transfer of power at the same time, but also bear the cylinder and material gravity in the direction of material flow, resulting in the rolling ring and the welding body of the force concentration, easy to cause open welding, Affect normal production operations. In addition, the welding stress of the whole welding between the roller ring and the cylinder is large. Due to the large shape of the roller ring, the heat treatment after welding is difficult, which is also an important cause of weld cracking.
The purpose of the utility model is to provide a compost trommel screen roller ring assembly structure which solves the roller ring better
Stress concentration problem in welding with cylinder.
Our new compost trommel screen technology is achieved by the following measures, including the cylinder and the roller of the compost trommel screen, which are characterized as: the roller is welded to the cylinder via a connecting plate; The connecting plate is a butterfly shaped connecting plate with one end narrow and the other end wide in the butterfly
The two ends of the shaped connecting plate are processed with plug welding holes; The butterfly connecting plate is arranged successively in the gap between the roller ring and the cylinder,
The narrow end is welded to the roller ring, and the wide end is welded to the cylinder body at the edge of the butterfly connecting plate and the plug welding hole
Inside. A wear-resistant rubber layer is arranged on the outer surface of the rolling ring.
A beneficial effect of the utility model included is that the assembly structure of the roller ring is welded to the cylinder by means of a butterfly connecting plate
On the top, the butterfly - shaped connecting plates are arranged in turn. The roller ring is connected with the cylinder through the transition of the butterfly connecting plate, so that the roller ring is transmitted in the radial direction
The force and axial force have appropriate cushioning effect. The weld adopts intermittent welding and plug welding hole welding, so that the welding stress can be dispersed And reduce the welding deformation in the welding process. The outer rubber of the rolling ring improves the wear resistance of the rolling ring and increases The service life of the rolling ring increases the efficiency of power transmission; And the connection plate together with a double damping effect. welded Strong connection, stress dispersion, small deformation and high efficiency, suitable for all sizes of compost trommel screen.
