本文重点介绍一种运用独立的循环滚动体做为啮合副的减速器。它比目前广泛应用的齿轮、蜗轮、摆线针齿减速器,谐波减速器结构都简单,适于大批量生产。由于采用可循环滚动体(钢球或钢柱)构成的啮合副取代传统的齿啮合副传动。因此从根本上解决了齿传动副抗弯曲强度不足的薄弱环节。新结构中的滚动体啮合副,几乎在纯滚动状态下工作。因此当选用相同材质时,滚道减速器可比其他类型的减速器,整机重减轻1/3,而零件总数减少30—40％。滚道减速器整机外型见图1。滚道减速器分解结构图见图2。
This article focuses on the use of an independent circular rolling body as a meshing pair reducer. It is more widely used than the current gear, worm gear, cycloid gear reducer, harmonic reducer structure is simple, suitable for mass production. Due to the use of a recirculating rolling element (steel ball or steel column) to form the meshing deputy to replace the traditional gear meshing deputy drive. Therefore, a fundamental solution to the weakness of the anti-bending strength of the tooth gear pair is weak. The new structure of the rolling body meshing pair, almost pure rolling state work. Therefore, the election of the same material, the roller reducer than other types of reducer, the whole weight reduction of 1/3, and the total number of parts reduced by 30-40%. Raceway reducer appearance see Figure 1. Raceway reducer decomposition structure shown in Figure 2.
