Attachment: Wimbledon Centre Court introduced a new retractable roof
Roof both open or closed can provide robust and secure ( does not slip ) of the venue. In the closed position , the natural light through the translucent roof exposure to the grass in any adverse weather conditions can play a protective role on the grass . Roof design itself as " collapsible hexagonal design ", when not using the roof , the roof can be folded into a high compression zone. Even the roof closed, the roof can also Precision bearing a transparent "open" feeling. The entire roof area of 5200 square meters, developed by a special waterproof material , very strong and full of flexibility. The key elements of the roof design when the roof is in the closed state, a lot of natural light can be irradiated to the grass. Airflow system from the closed space of the condensation detached , so as spectators and players and provide a most comfortable environment inside .
Retractable roof comprises a total of nine base plate is divided into two parts: one is 4 , and the other part of the 5 . On either side of each plate are fixed with angled steel . There are 10 frames across 77 meters of the stadium . Each steel wheels supported by a set of ports can be installed in the center court along both sides of the backing bearings move . Ready to close the retractable roof , the northernmost part of the stadium to keep the folded state , parked in another part of the southern end . To ensure the accuracy of the roof moves , you need to install a high-precision electronic actuators, servo motor and rocker synthesis system . This system will separate the steel , while steel between the upper and the steel parts of substantially begin until the two parts of the top center of the pitch joints combined stacked flat . Steel is installed on the bottom of the hinge a number of similar components. Schaeffler FAG spherical roller bearings assembled in these hinge . These bearings due to friction is small, and can be carried out right kind of compensation is selected. These bearings are grease lubricated through high-performance , during use, requires minimal maintenance
