Zusammenfassung: | PURPOSE:To prevent abrasion of a tooth surface by feeding a bevel-gear speed reduction gear with oil on detecting that the bevel-gear speed reduction gear generates heat more than a designated temperature. CONSTITUTION:When tooth surfaces of a fixed bevel gear 1 and an oscillating bevel gear 2 run short of lubricating oil, the bevel gears 1, 2 generate heat. When the temperature of generatd heat is more than a designated temperature, a detection sensor 4 is deformed so that a switch 23 is pressed by the detection sensor 4, thereby to operate an oiler 5. Oil is supplied to tooth portions of the bevel gears 1, 2 and a presser 19 through an oil feed pipe 24 from the oiler 5 to keep the tooth portions and the presser 19 from generating heat. |
