Title:
TENSION COMPENSATION DEVICE WITH BRAKE FUNCTION
Document Type and Number:
WIPO Patent Application WO/2011/072508
Kind Code:
A1
Abstract:
A tension compensation device with brake function at least comprises a main shaft (10) and a shell (20) rotating relative to each other. One of the main shaft (10) and the shell (20) is used to connect with a tension component (30). An elastic component is disposed between the main shaft (10) and the shell (20) so as to provide a torque between the same, which reacts against the tension component (30). The tension compensation device also comprises a brake mechanism in whole or in part. When the tension compensation device is disabled as a result of the fracture of the tension component (30), the brake mechanism is triggered by the gravity to implement the brake function. The tension compensation device uses the gravity to trigger the brake mechanism, and implements the brake function at low cost, and has the advantages of simple structure, high reliability, wide application and so on.
