2results about How to "Reduce additional load" patented technology

The utility model discloses a kind of low vibration bearing with optimized retainer structure belong to bearing technical field, including inner ring and outer ring, evenly be provided with rolling element between inner ring and outer ring, rolling element outside is provided with retainer, retainer includes first side plate and second side plate, there is array distribution in between first side plate and second side plate pocket, pocket and first side plate and second side plate between fixed connection, pocket and pocket between fixed connection there is pocket crossbeam.The utility model uses above-mentioned a kind of low vibration bearing with optimized retainer structure, reduce the collision of rolling element and retainer, inner ring and outer ring, enhance the overall rigidity of retainer, avoid rolling element position deviation, inhibit bearing vibration;Oil reservoir can store lubricating oil, reduce the friction and abrasion of rolling element and pocket, raceway, prolong the service life of bearing;Retainer uses aluminium alloy material, reduce centrifugal force when high speed operation, reduce the additional load to bearing overall, indirectly reduce vibration.

This invention discloses a rapid mooring device and method for dock ships, comprising a base assembly, a rotating component, a sliding force transmission component, a tensioning mechanism, a tie rod assembly, and a mechanical locking assembly. The rotating component and the sliding force transmission component constitute a multi-degree-of-freedom follower mechanism to adapt to changes in the force direction of the mooring line. The tensioning mechanism drives the sliding force transmission component to achieve tensioning and release. The mechanical locking assembly includes a jump plate and a wedge block assembly for rapid coarse adjustment and precise locking of the load. Through the above structure, the small boat can achieve adaptive force adjustment during the floating and bottoming processes of the dock ship, and complete the switch of load from driven bearing to mechanical bearing on the deck. The method includes connection, tensioning, adaptive adjustment, and mechanical locking steps. This solution requires no underwater operation, has high operational safety, high mooring efficiency, and is suitable for rapid mooring and release operations of large-tonnage small boats.
