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,...
