Äntriebstroinniel for conveyor systems

comes.

To avoid this slippage, it has been screwed on the drive drums wood strips that are similar r a gear in the wire netting and thus intervene

ensure pressure-free transport of the wire mesh. However, there is the big downside here, that the tensioned wire mesh strongly attacks the wood. and damaged. Splintered haul pieces get caught in the drive units and in the entire system and sometimes lead to considerable damage. The maintenance costs for such systems are therefore considerable.

The innovation relates to a drive drum for conveyor systems, especially those in which an endless mesh of wire or plastic is used as a conveyor belt is guided over drive rollers.

Usually when transporting a wire mesh over bolts that serve as drive drums Steel creates a slip between the wire mesh and the rollers that is so great that the conveyor system has already started with small differences in load to a standstill

The task of the innovation is to create a cheaper design of such slip-preventing drive drums.

According to the control, this is achieved in that on the * The outer surface of the internal drive drums is preferably even Distance profiles made of rubber or one of the elastomers are arranged.

The profiles are roughly the same length as the drive C drum .. you are preferably on the drive drum

Mottled profiles of the same or different lengths can also be screwed onto the drive drum in the axial direction behind it. They have an approximately rectangular or trapezoidal cross-section. Your base area lying against the drum can be adapted to the curvature of the drive drum.

Si β profiles are ~ sTrr giigs ij.gl.so τ ti

Made of an abrasion-resistant material quality, like that of a Shore hardness of about 20 to 90 is flat.

In the following, inflation is shown on the basis of the annex

Drawings described in more detail:

Based on the known, provided with wooden strips embodiment of the drive drums are according to the

Innovation in rubber profiles 1 ^; injected and applied in the axial direction at a distance 2 next to each other on the drive drums 3 of the transport system, preferably screwed on. The rubber profiles 1 have an approximately rectangular or trapezoidal cross-section, and their base 4 is adapted to the curvature of the drive drum. The lengths of the rubber profiles 1 and the drive drum 5 are preferably the same.

Like the well-known wooden strips, these also grip rubber— profile 1 sit yours. Edges 5 in the to be transported Wire mesh and ensure a slip-free movement of the conveyor belt.

2ur production of the profiles 1 is advantageously a Material quality of high stability and great hardness selected with a Shore hardness of about 20 to 90. The Gusnii is then highly abrasion-resistant, but still has a certain elasticity compared to the wire mesh, so that the profile - edges 5 no abrasion occurs and the run of the transport siage is no longer caused by abraded or chipped material. rial parts is disturbed. The maintenance costs of the system decrease thus to a minimum, and a trouble-free run over a: long duration is guaranteed. In addition, the Transport system when using wire mesh as a conveyor belt due to the Guioisiprofile considerably noise reduction. as direct contact between metal and metal is avoided «
