The invention relates to an improved swash plate. The improved swash plate comprises a ball bearing, a rotating assembly and a non-rotating assembly, wherein the non-rotating assembly comprises a non-rotating body, a knuckle bearing and a second anti-twisting assembly, an annular groove is formed at an upper portion of the non-rotating body, an inner circumferential surface of the annular groove is connected with an outer ring of the ball bearing, a second anti-twisting assembly is hinged to an outer circumferential surface of the non-rotating body, the inner circumferential surface of the non-rotating body is connected with an outer ring of the knuckle bearing, the rotating assembly comprises a rotating body, a pull rod and a first anti-twisting assembly, an outer ring of the rotating body is connected with an inner ring of the ball bearing, a lower end of the first anti-twisting assembly is hinged into a corresponding groove in the inner periphery of the rotating body, a lower end ofa pull rod is connected into a pull rod installation groove in the inner periphery of the rotating body through a hinge piece. The improved swash plate is advantaged in that one side of the groove inner ring of the non-rotating body is connected with the outer ring of the ball bearing, so the radial size of the device is reduced, an inner surface of an outer annular body extending from the interior of the non-rotating body is connected with the outer ring of the knuckle bearing, the structure is simplified, the size and weight are reduced, and therefore air resistance is reduced.
一种改进的倾斜盘,包括球轴承、旋转组件和非旋转组件,该非旋转组件包括非旋转体、关节轴承和第二防扭组件,在该非旋转体的上面设有环形凹槽,环形凹槽的内周面与该球轴承的外圈连接;在非旋转体的外周面铰接有第二防扭组件,非旋转体的内周面与关节轴承的外圈连接;旋转组件包括旋转体、拉杆和第一防扭组件,旋转体的外圈与球轴承的内圈连接;第一防扭组件下端铰接在旋转体内周的对应槽内;拉杆的下端通过一个铰接件连接在该旋转体内周的拉杆安装凹槽内。有益效果是:非旋转体凹槽内圈一侧和球轴承外圈连接,减小了装置的径向尺寸;非旋转体内部延伸外环形体内表面和关节轴承的外圈连接,简化了结构,减小了体积和重量,从而减小了空气阻力。
