Embodiment Construction

[0022] exist figure 1 A conveyor belt is schematically shown as an example of a continuous conveyor in . Its endless conveyor belt 1 runs in a loop between drive rollers 2 and guide rollers 3 . Heavy bulk goods 4 , such as ore or crushed rock, are delivered to the part of the conveyor belt 1 that just forms the upper run and are conveyed substantially horizontally from left to right in the drawing. Below the conveyor belt 1 are arranged idler rollers 5 which support the weight of the conveyor belt 1 and the bulk goods 4 .

[0023] The conveyor belt is driven with a high torque by a slow-running multi-pole synchronous motor 6 . if available at figure 2 As can be seen in , the synchronous motor 6 directly drives the drive roller 2 of the conveyor belt, ie there is no intervening mechanical transmission. The operating speed of the drive roller 2 is approximately 40 U / min, so that the synchronous motor 6 also has a rated speed of 40 U / min. The synchronous motor 6 delivers a ...

Abstract

A continuous conveyor such as, for example, a conveyor belt for transporting heavy bulk materials or unit loads comprises an endless tractive transport means that revolves between a driving roller and a return roller. The driving roller is driven by a permanently excited multi-pole synchronous motor that delivers a very high torque at a comparatively slow nominal speed. The synchronous motor can drive the driving roller directly or alternatively via a single-stage step-down gear with low reduction factor. The inventive drive is characterized by a mass moment of inertia that is up to 10-times lower than in conventional drive systems. In this way, the risk of damaging or even tearing the belt during disruptions is substantially reduced such that the operational reliability significantly increases.

Description

technical field [0001] The invention relates to a continuous conveyor (Stetigförderer), which is used, for example, in mining, surface mining or underground mining or in loading and unloading of ships, silos, etc., for conveying large quantities of bulk goods, such as sand, rocks or ore as well as for conveying very heavy single-piece goods (Stückgut). In this case, the bulk goods or individual goods are loaded onto the conveying traction means in the delivery station and conveyed to the output station or transfer station. Background technique [0002] A typical example of a continuous conveyor is a conveyor belt used to carry away crushed ore. The conveyor belt runs on support rollers supported in a longitudinally extending support structure made of steel profiles. The drive station includes, in addition to one or more drive shafts, at least one electric motor, which is designed primarily as an asynchronous motor and operates at a relatively high rotational speed (for exa...
