Patent number: 11953063Abstract: A normally closed disc clamp system includes a housing with a rotating disc, a brake ring and a pressure-enhancing ring arranged therein. When only a first chamber is supplied with fluid, the fluid pushes the brake ring to release the rotating disc. When only a second chamber is fed with fluid, the fluid pushes the brake ring to keep the rotating disc in the braking state, and pushes the pressure-enhancing ring to compress an elastic unit. The energy generated by the compression of the elastic unit acts on the brake ring through the fluid, so that the brake ring achieves a double pressurization effect. If the action of the fluid fails, the brake ring can still provide a braking effect to the rotating disc through the elastic unit to improve operational safety. Further, the present invention further provides a rotating table using the normally closed disc clamp system.Type: GrantFiled: August 31, 2021Date of Patent: April 9, 2024Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Peng-Wen Chen, Chien-Yu Lin, Li-Wen Huang
