实际机械中,减速器由于结构紧凑,效率较高,传动比准确可靠,使用维护简单,因而应用非常广泛。减速器一般由刚性密封箱及装在其中的一对或几对相啮合的齿轮、蜗轮、蜗杆所组成。这种由一系列齿轮所组成的传动系统,我们通常称为轮系。由于轮系在实际生产中的重要性,轮系这部分内容在机械传动知识中占有重要地位,在教学大纲中分配大量学时。 在教学中,定轴轮系传动比的推导、效率的计算较易掌握,而
In actual machinery, the reducer is widely used due to its compact structure, high efficiency, accurate and reliable transmission ratio, simple operation and maintenance. Reducer generally consists of a rigid sealed box and one or several pairs of meshed gears, worm gears and worm gears. This consists of a series of gear transmission system, we often called the wheel train. Due to the importance of the wheel train in actual production, this part of the wheel train plays an important role in the knowledge of mechanical transmission, allocating a large number of class hours in the syllabus. In teaching, the derivation of the gear ratio of the fixed-shaft gear train and the calculation of the efficiency are easy to grasp
