Abstract
A gear is disclosed with a heavy loading capacity which has teeth roots between adjacent gear teeth and contact area patterns on the face of each gear tooth. Each tooth root includes a concave fillet running substantially in a direction of the rolling element generator line of the gear. The top of each tooth is substantially equidistant and a mirror image of the tooth root fillet.
Claims11
A gear with heavy load capacity having a tooth root between two adjacent gear teeth and a contact pattern on each gear tooth comprising, each tooth root forming a concave fillet running substantially in the direction of a rolling element generator line tangent, a tooth top of each tooth having a form which is equidistant from a tooth root of a mating gear, the fillet form of the tooth root between two adjacent gear teeth being equidistant from the contact pattern of the two adjacent gear teeth.
A bevel gear wheel having heavy load capability comprising a tubular section having an axis parallel to an axis of the bevel gear wheel, a flange section extending radially outwardly of the tubular section, a rolling cone generatrix of the bevel gear extending from an edge of the flange section to an edge of the tubular section, a tooth root between each two adjacent gear teeth having the form of a concave fillet extending substantially in the direction of the rolling cone generatrix, each gear tooth having a top formed in a mirror image shape to the tooth root about the rolling cone generatrix, each point of the tooth root being equidistant from a contact pattern on a surface of each of said adjacent gear teeth.
