Title: TRANSMISSION SPEED REDUCTION DEVICE
Abstract:
A transmission speed reduction device, comprising: a worm assembly (1) which is located within a container body (2), a worm wheel assembly (3) and an output axle (4); an input axle (11) is provided on the worm assembly (1), while the worm assembly (1) and the worm wheel assembly (3) achieve primary stage mesh transmission therebetween by means of worm teeth which are provided on the worm assembly (1) and a first worm wheel tooth (34) which is provided on the worm wheel assembly (3); the worm wheel assembly (3) and the output axle (4) achieve secondary stage mesh transmission by means of an intermediate rotary body (32) which is provided on the worm wheel assembly (3) and a rotary disc assembly (5) which is mounted on the output axle (4). The transmission speed reduction device has a compact structure, a large transmission ratio, is high precision, has low friction wear, and is easily applicable in the development of industrial production and manufacturing, while being low cost and being suitable for precision heavy load transmission scenarios having large transmission ratio requirements and volume restrictions, such as joints of industrial robots and the like.
