Problems solved by technology

In addition to the requirement that the enveloping circle be as small as possible for a given chain bearing force, especially for the horizontal chain link in the area of ​​its head and in the area of ​​the contact surface on the teeth of the sprocket that cooperates with the head special attention should be given to the design of the chainring, since it is known (DE 196 10935 A1) that the force-transmitting face of the head of the horizontal link, especially based on the linear contact between the side of the head and the sprocket teeth, can suffer the greatest crushing force, which can result in disproportionate head wear by flattening or notching (so-called Entenbürzel)

Embodiment Construction

[0025] figure 1 Shown are two horizontal links 1 and two vertical links 2 connected to them in a plow chain generally indicated by reference numeral 10, which are designed identically to each other in the illustrated embodiment, And as a die forging, it is composed of two chain link edges 3 parallel to each other and the chain head 4 that connects them and is designed as an arrowhead at the top of the horizontal link 1 and the vertical link 2. exist figure 1 and 2Shown is the plow chain 10 meshing with the sprocket teeth 51 of a sprocket 50, which is selectively driven in one or the other direction of rotation by means of a drive (not shown further) during operation of the underground plowing plant. The sprocket 50 is provided with chainring pockets 52 between two adjacent sprocket teeth 51 , which are delimited by tooth flanks 53 of the teeth 51 . Here, the device is designed in such a way that the tooth flanks 53 delimiting the chain ring socket 52 are provided with spher...

Abstract

Chain transmission arrangement and sprocket and chain assembly employed therein with the bow flanks of the horizontal chain links (1) of the chain assembly (10) exhibiting a concave trough at least below an equatorial line (7) and the chain link pockets (52) of the sprocket (50) that receive the horizontal chain links at their tooth flanks (53) in the contact areas (55) to the chain links (1) having a convex crown shape to match the trough bow flank. This significantly reduces the surface pressures between the two parts.

Description

technical field [0001] The invention relates to a chain drive or steering device for chain-drawn mining or conveying equipment, especially in underground mining, for example for plowing equipment or chain-slab conveyors, comprising a sprocket and a sprocket-driven and necessary A time-driven chain, in which the chain consists of vertical links and horizontal links, and the sprocket has a plurality of sprocket teeth evenly distributed on its circumference and a link pocket between every two adjacent teeth , the chain ring pockets are bounded by the tooth sides of the sprocket teeth and respectively accommodate the horizontal links of the chain. The horizontal link has a head. When the horizontal link is embedded in the chain ring pocket of the sprocket, the head constitutes the force transmission area. , Here, the head is designed in an arrow shape and has head sides arranged on both sides of the center of the arched head. In addition, the present invention relates to a chain,...
