Excavator pushing and pressing mechanism directly driven by motor
The invention discloses an excavator pushing and pressing mechanism directly driven by a motor. The excavator pushing and pressing mechanism comprises a motor, a pushing and pressing shaft, a gear anda rack, wherein the motor comprises a stator, a rotor and a motor shaft, the stator is arranged on the periphery of the rotor in a sleeve mode, the rotor is arranged on the periphery of the motor shaft in a sleeve mode, the rotor is connected with the motor shaft through splines, the splines comprise a rotor inner spline of the rotor and a motor shaft outer spline of the motor shaft, an accommodating space is formed between the rotor internal spline and the motor shaft external spline, an elastic body is arranged in the accommodating space, the pushing shaft and the motor shaft are of an integrated structure, the gear is arranged on the pushing and pressing shaft, and the pushing and pressing shaft drives the rack through the gear. According to the excavator pushing and pressing mechanismdirectly driven by the motor, rack and gear transmission is directly used, the structure is simple, the transmission efficiency is high, noise is low, the reliability of the pushing and pressing mechanism is improved, the failure rate of the pushing and pressing mechanism is reduced, and the maintenance and repair cost is reduced.
本发明公开了一种电机直驱的挖掘机推压机构，包括电机、推压轴、齿轮以及齿条；所述电机包括定子、转子以及电机轴，所述定子套设在所述转子外周，所述转子套设在所述电机轴外周，所述转子与所述电机轴通过花键连接，所述花键包括所述转子的转子内花键与所述电机轴的电机轴外花键，所述转子内花键与所述电机轴外花键之间设有容纳空间，所述容纳空间内设置有弹性体；所述推压轴与所述电机轴为一体结构；所述齿轮设置在所述推压轴上，所述推压轴通过所述齿轮驱动所述齿条。上述电机直驱的挖掘机推压机构直接利用齿条、齿轮传动，结构简单，传动效率高，噪音小，提高了推压机构的可靠性，降低了推压机构的故障率，降低了维护及维修成本。
