Document Type and Number:
Japanese Patent JP2016070285
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a speed reducer capable of reducing load applied to a wheel member added to a frictional member.SOLUTION: A speed reducer 1 is constituted by a sun rolling member 11; two or more planetary rolling members 12; a carrier pin 13 rotatably supporting the planetary rolling members 12; a wheel member 14 rotatably supporting two or more planetary rolling members 12; an annular rolling member 2 outwardly enclosing two or more planetary rolling members 12 so as to cause the planetary rolling members 12 to be rotated around a rotating center axis J1 through contact with the planetary rolling members 12; a casing member 16 outwardly enclosing the sun rolling member 11 and the planetary rolling members 12 to support the rolling members 12; and a bearing 17 for rotatably supporting the wheel member 14 in respect to the casing member 16. The bearing includes the output bearing 17 arranged between an inner peripheral surface of the casing member 16 and a carrier pin supporting part 141; and a wheel bearing 18 arranged between an outer peripheral surface of the casing member 16 and an inner peripheral surface of a cylindrical part 162.SELECTED DRAWING: Figure 1
