Abstract
Toggles are disclosed for toggle connections of conveyor pans of a chain scraper conveyor or conveyor troughs of a mining machine guide. In providing a toggle and a toggle connection, with which high axial forces can be transmitted while, at the same time, maintaining high angular mobility of the pans and troughs, shoulder areas of the toggle are designed so as to be spherical. Because of the spherical design of the shoulder areas, the vertical mobility of adjoining conveyor pans is improved while at the same time the transmission of axial tensile forces to the toggle heads is optimized.
Claims28
A toggle adapted for use in toggle connections of conveyor pans of a chain scraper conveyor or for guide troughs of a mining machine guide, the toggle comprising two toggle heads which are connected in one piece with one another by a shaft extending therebetween, each toggle head defining an oppositely directed head end, the width of the shaft being tapered, wherein the toggle heads define shoulder areas on the side facing the shaft, the shoulder areas sloping toward the shaft, and the shoulder areas having a spherical configuration, and wherein the toggle heads are rounded at least on (i) the lower side of the toggle and (ii) on the upper side of the toggle from one side to the other, with the radius of curvature (RO,RU) on the lower side of the toggle or the upper side of the toggle being identical to the radius of curvature (RS) on the shoulder areas.
A toggle adapted for use in toggle connections of conveyor pans of a chain scraper conveyor or for guide troughs of a mining machine guide, the toggle comprising two toggle heads which are connected in one piece with one another by a shaft extending therebetween, each toggle head defining an oppositely directed head end, the width of the shaft being tapered, wherein the toggle heads define shoulder areas on the side facing the shaft, the shoulder areas sloping toward the shaft, and the shoulder areas having a spherical configuration, and wherein the radius of curvature (RS) on the shoulder areas is smaller than the distance (B) of the side areas on the toggle heads and larger than the maximum depth (T) of the shaft or the maximum depth (T) of the toggle heads.
