DE3126513C2 - Noise-dampened plate conveyor belt - Google Patents

Abstract

Modular belt, consisting of a large number of plate or grid-shaped modules made of plastic, which have several closed or almost closed eyelets at a distance from one another on two opposite module edges, which form a unit with the modules and can each be inserted into the spaces between the eyelets of adjacent modules are and are connected to these by cross bars to form the belt, the deflection and drive of the belt being carried out by gear wheels arranged on shafts, the teeth of which engage projections or eyelets arranged on the underside of the modules or engage in recesses of the modules, and besides the gear wheels (1) noise damping disks (2) made of slightly elastically deformable material are arranged, the diameter of which is greater than the diameter (I) of the circle on which the bottoms of the grooves formed between the teeth lie.

Description

The invention relates to a work roller for one end gearwheels. , __, ". . . «· Ι" m

loose conveying means consisting of one on a 35 link conveyor belts 4 consist of a plurality

Projections or in recesses on the underside rods are connected to each other. The crossbar & be

of the conveying means intervene and from both sides of the run through eyelets, the eyelets arched side by side

Grip the gearwheel arranged on a circle - arranged plates in one another,

elements for the conveyor, with a diameter of 40. The drive and deflection of the link conveyor

of the circle is larger than the diameter of the toothed belt 4 is carried out by toothed wheels 1. whose teeth 6 are

wheel base circles * ^neither ^ ¹ protrusions on the underside of the modules

Such drive rollers for conveyors are attacked or engre.fen in recesses of the modules. the US-PS 33 11 220 known, wherein a on a The gears 1 are arranged on a shaft 3, the Drive shaft arranged gear the drive for a 45 is driven by conventional means, as far as endless chain forms To compensate for wear, the gears are not only used for deflection, if the gear wheel has wear pads there, which are interchangeable on both sides in addition to the preferably made of plastic are and ensure that the chain stationary gears 1 are ring disks 2 angeordimmer at the same distance from the shaft center, the width of which is greater than the width of the gears point rotates so that no disruptive wear occurs so 1 and consisted of a soft, elastic material can. The gears can be used as long as you like. The annular disks 2 consist in particular of Use its foam, being both rubber foam as well

Disadvantageously, such drives can be used for these or plastic foam. It is

The object of the invention is to create a drive roller for a diameter that corresponds to the diameter A of the a link conveyor belt, in which the tip circle formed with relative teeth 6 of the gears t, using simple means, increases the noise development and the diameter of the ring disk ^ 2 is Hch is reduced, so that such a band can also be used in at least larger spaces than the diameter of the gearwheel, without the root circle on which the bottom of the groove is unacceptably formed by noises 6 between the working staff Grooves 7 is stigt is. The noise dampening means should also not hinder the trouble-free operation of the belt on the outside next to the ring disks 2 are made of solid material, the diameter of which and the drive power of which are not or only slightly less than the diameter B of the gear wheel base.

ses, ensuring that the outside edges of the annular disks can deform sufficiently, on the other hand, these disks made of soft, elastic material but are adequately supported

According to the exemplary embodiment, the support disks 5 arranged next to the annular disks 2 are through Tie rod 8 interconnected so that the gears 1, the annular disks 2 and the support disks 5 a Form a unit that can be assembled by itself.

The ring disks 2 can be arranged both on shafts that are driven, and on shafts, whose gears 1 only deflect the link belt to serve. The effect of the annular disks 2 is further improved by the fact that they are at their outer edges, d. H. be chamfered, chamfered or rounded on one or both sides on the circumference

Another embodiment of the noise damping is that when using very soft materials for the annular disks 2, these have such a width that they extend from one to the adjacent gear 1 extend, so conically or are cylindrical and fill the said free space next to the gears.
