Title:
減速機付き油圧走行モータ
Document Type and Number:
Japanese Patent JP6478097
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic travel motor with a speed-reducer in which a lubricant in a speed-reducer chamber effectively acts on a planetary gear.SOLUTION: A hydraulic travel motor 10 with a speed-reducer is basically composed of a hydraulic travel motor 11, and a speed-reducer 14, and coupled by a spline 22. When a carried 54 is spline-coupled to a motor casing 13, a pin member 92 inserted for holding a planetary gear group 43 in the carrier 54 is engaged between a plurality of projecting portions 21 formed on one end surface 37 of the motor casing 13. Therefore, the planetary gear group 43 held by the carrier 54 can be positioned so as to contact with a lubricant in the speed-reducer 14, so that the lubricity of the planetary gear group 43 is improved, thereby reducing variations in a gear life of the hydraulic travel motor 10 with the speed-reducer and improving a gear life.SELECTED DRAWING: Figure 1
