Problems solved by technology

[0004] However, when the load on the axle in the axle box (rocker arm) is large, the tooth surface of the bevel gear installed on the axle may be damaged due to the bending of the intermediate shaft (first propeller shaft) pivotally supported in the axle box. (pitching), the condition of missing teeth
Therefore, the durability of the power transmission mechanism that transmits power to the axle may be reduced and the power transmission efficiency may be reduced.

Abstract

The invention provides a seedling planting machine which is characterized in that through relieving bending of an intermediate axle in a car axle box, tooth surface damage and tooth missing generated in a bevel gear are reduced so as to improve durability of a power transfer mechanism. The seedling planting machine is a seedling planting machine transferring power to the car axle box through a gearbox from an engine to drive car wheels, the bevel gear is arranged in the car axle box and is used as a speed reduction mechanism, with use of the bevel gear, the power is transferred to the car axle of the car wheels from the gearbox, moreover, an axle portion of the bevel gear is provided with an axle-supporting portion, and the axle-supporting part is provided with a bearing component.

Description

technical field [0001] The invention relates to a seedling planting machine. Background technique [0002] Japanese Patent Application Laid-Open No. 2008-228707 discloses a seedling planting machine in which the power of an engine is transmitted to a rocker arm through a gearbox to drive wheels. [0003] The output shaft protruding from the gearbox transmits power to the first transmission shaft arranged in the rocker arm through the bevel gear, and the first transmission shaft transmits power to the axle fixed to the wheel through the bevel gear. [0004] However, when the load on the axle in the axle box (rocker arm) is large, the tooth surface of the bevel gear installed on the axle may be damaged due to the bending of the intermediate shaft (first propeller shaft) pivotally supported in the axle box. (pitching), the condition of missing teeth. Therefore, the durability of the power transmission mechanism that transmits power to the axle may decrease and the power trans...
