众所周知,对于叶片式液压马达定子曲线,主要应考虑其连续性、平滑性、叶片运动过程的径向速度和加速度等因素,以满足径向不脱空、吃油均匀、转速稳定、径向冲击小等要求。国内外常采用的过渡曲线(指加速度曲线)有正弦、余弦、等加速、等减速、阿氏曲线等,或者是它们的组合。本文介绍和分析YM7.5型低速大扭矩叶片液压马达(排量为7.5升/转,额定转速60转/分,理论扭矩780公斤米,额定工作压力65公斤力/厘米~2)的特殊型定子曲线(见图1)及其加工方案。
As we all know, for the blade hydraulic motor stator curve, the main consideration should be its continuity, smoothness, the radial movement of the blade speed and acceleration and other factors to meet the radial not empty, uniform oil, stable speed, radial impact Small and other requirements. The transition curve (referring to the acceleration curve) commonly used at home and abroad have the sine, cosine, such as acceleration, deceleration, Aberdeen, etc., or a combination thereof. This article introduces and analyzes the special type of YM7.5 type low speed and high torque hydraulic motor with a displacement of 7.5L / rev, a rated speed of 60rpm, a theoretical torque of 780kg and a rated working pressure of 65kg / cm2. Stator curve (see Figure 1) and its processing options.
