Document Type and Number:
Japanese Patent JP5822392
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an eccentric rocking type reduction gear that can smoothly supply a lubricant to each part inside a reduction gear at a low cost without complicating the shape of external gears.SOLUTION: The eccentric rocking type reduction gear G1 includes first and second external gears 22, 24 which rock, an internal gear 26 in which the first and second external gears 22, 24 are internally meshed, and first and second carrier bodies 32, 34 provided in side parts in the axial direction of the first and second external gears 22, 24. Inner pin holes 22A, 24A penetrated in the axial direction are provided at positions offset from centers O2, O3 of the first and second external gears 22, 24. A clearance δ2 in the axial direction is secured between one angular ball bearing (38) out of first and second angular ball bearings (main bearings) 36, 38 supporting the first and second carrier bodies 32, 34 on a casing 31, and the second external gear 24. A projected part 34F is formed in the axial direction abutting on the second external gear 24 further on the radially inner side than the inner pin hole 24A on the second carrier body 34.
