METHOD AND DEVICE FOR CONTROL OF DEGREE OF WEAR OF SPROCKETS OF MINING CONVEYORS Russian patent published in 2023 - IPC B65G23/06 F16H7/06 F16H55/30 F16H57/01 

FIELD: wear assessment.

SUBSTANCE: sprocket (1, 1') is proposed, containing teeth (3) for engaging with one or more chains (20), equipped with support connecting elements (16), which detachably hold the body (17) at the reference level, for example, a tensioned wire (17'), at a predetermined position. The reference level body (17) is a temporary reference or support element or surface from which the position of the wear surfaces (10) of the teeth (3) of the sprocket can be determined visually or by measurement, in particular in the radial direction (Dr). The teeth (3) may additionally contain a set of marks (31, 32, 33) corresponding to the control planes spaced at angles (P1, P2, P3) intersecting along the axis of the sprocket (X). The marks (31, 32, 33) are preferably located on the ridge or radially outwardly extending surface (6) of the teeth (3) and are used to determine wear in the circumferential direction (Dc).

EFFECT: proposed device can be used to more easily and reliably assess the degree of wear in both radial and circumferential directions on sprockets with one, two or more sets of teeth to engage with one, two or more chains, and the device can be used by relatively inexperienced personnel without using special tools with tensioned or loose chains on a sprocket.
