Title:
POROUS ULTRASONIC TRANSMISSION PAIR
Document Type and Number:
WIPO Patent Application WO/2019/019754
Kind Code:
A1
Abstract:
A porous ultrasonic transmission pair, comprising a left ring (1), a high-strength outer sleeve (2), a guide rail sleeve (4), and a right ring (5). The high-strength outer sleeve (2) is sleeved on the guide rail sleeve (4). The left ring (1) is fixedly disposed between the high-strength outer sleeve (2) and the left end of the guide rail sleeve (4). The right ring (5) is fixedly disposed between the high-strength outer sleeve (2) and the right end of the guide rail sleeve (4). The guide rail sleeve (4) is provided with a through radial hole group (41) so that the exterior of the guide rail sleeve (4) is communicated with the inner hole. A vibrating sleeve ring (3) is provided between the high-strength outer sleeve (2) and the guide rail sleeve (4). A gap is formed between the inner hole of the vibrating sleeve ring (3) and the exterior of the guide rail sleeve (4). The exterior of the vibrating sleeve ring (3) is fixedly attached in the inner hole of the high-strength outer sleeve (2). The vibrating sleeve ring (3) can radially vibrate at a high frequency. The porous ultrasonic transmission pair can vibrate at a high frequency during work to reduce friction between a thread pair, a spline pair, and a linear guide rail pair, and thus, the durability and the motion transmission accuracy are improved, the service life is prolonged, and the manufacturing and using costs are reduced.
