Procedure for Determination of Probability of Absence of Interference from Interlocking of Asymmetric Rod Blanks During Gripping in Hopper Feeding-Orienting Devices

The article describes the probability of absence of interference from interlocking of asymmetric rod blanks during their gripping in mechanical disk hopper feeding-orienting devices. Stages of construction of mathematical models of probability of absence of interference from interlocking of rod billets with explicit and implicit asymmetry are considered. Obtained mathematical dependences of probability of absence of interference from interlocking of rod cylindrical blanks with explicit asymmetry and having implicit asymmetry of blanks of three shapes – stepped cylindrical, with spherical end and end in the form of truncated cone are given. Presented expressions for description of all coeffi cients of mathematical model make it possible to estimate probability of absence of interference from interlocking of blanks during their gripping in mechanical disk hopper feeding-orienting devices depending on geometric parameters of blanks and coeffi cient of friction between their surfaces at their various combinations.
