摘要： The present invention is directed to a power transmission apparatus for a power driven lawn mower. The lawn mower has a housing, an engine mounted on the housing, a moving blade coupled to the engine and wheels which are swingably mounted on the housing. The swinging of the wheels moves the housing towards and way from the ground in order to raise and lower the housing to thereby raise and lower the lawn mower blade. The power transmission apparatus comprises a transmission mechanism and a transmission chamber for housing the transmission mchanism, the chamber including a guide structure. The transmission mechanism includes a drive shaft coupled to the engine and a single reduction gear mechanism coupled to the drive shaft and the wheels for transmitting the rotation of the drive shaft to the wheels. The reduction gear mechanism includes an engaging structure for engaging the guide structure in the chamber wherein the swinging movement of the wheels causes a corresponding movement of the reduction gear mechanism. The corresponding movement of the reduction gear mechanism is guided by the movement of the engaging structure in the guide structure.
摘要翻译： 本发明涉及一种动力驱动割草机的动力传递装置。 割草机具有壳体，安装在壳体上的发动机，联接到发动机的可动叶片和可摆动地安装在壳体上的轮子。 轮的摆动使壳体朝向和离开地面移动，以便升高和降低壳体，从而升高和降低割草机叶片。 动力传递装置包括传动机构和用于容纳传动机构的传动室，所述腔室包括引导结构。 传动机构包括联接到发动机的驱动轴和联接到驱动轴和车轮的单个减速齿轮机构，用于将驱动轴的旋转传递到车轮。 减速齿轮机构包括用于接合腔室中的引导结构的接合结构，其中车轮的摆动运动引起减速机构的相应运动。 减速齿轮机构的相应运动由接合结构在导向结构中的运动引导。

摘要： A cutter housing for use in a power-driven lawn mower has a substantially cylindrical skirt wall and a top wall covering the upper end of the skirt wall. The top wall has a substantially central recess for accomodating the engine of the lawn mower and includes a pair of half members positioned one on each side of the recess and lying substantially flush with each other in symmetrical and contiguous relation. The cutter housing also has a rear housing portion extending rearwardly in contiguous relation to the skirt wall and the top wall, and a partition disposed in the rear housing portion and dividing the rear housing portion into two spaces. The skirt wall, the top wall, the rear housing portion, and the partition are integrally molded of synthetic resin.
