Document Type and Number:
Japanese Patent JP2017133392
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the durability of an oil seal.SOLUTION: Tooth traces of gear teeth 23a and 24a of a driving gear 23 and a driven gear 24 are twisted in a direction discharging a lubricant in a gear chamber 22 toward each oil seals 51a, 51b through a driving shaft side bearing 42a or a driven shaft side bearing 42b by rotations of the driving gear 23 and the driven gear 24. Therefore, even if the driving shaft side bearing 42a is arranged between the driving gear 23 and the oil seal 51a in an axial direction of the driving shaft 17, and the driven shaft side bearing 42b is arranged between the driven gear 24 and the oil seal 51b in an axial direction of the driven shaft 18, the lubricant is efficiently supplied into each oil seal 51a, 51b.SELECTED DRAWING: Figure 4
