Support device for a shafting and wind turbine generator system

ActiveCN115875214BRoller bearingsBearing assembly
The application provides a support device for a shaft system and a wind turbine generator. The shaft system comprises a first shaft, a second shaft and a bearing arranged between the first shaft and the second shaft, the first shaft is sleeved on the outer circumferential side of the second shaft and can rotate relative to the second shaft through the bearing, the support device is arranged on the first end in the axial direction of the shaft system, the support device comprises: an axle end support, at least a part of the axle end support is rotatably supported on the outer side of the axle end surface of the first end of the second shaft in the axial direction; a connecting assembly, the connecting assembly is arranged between the first end of the first shaft and the axle end support in the axial direction of the shaft system; and a pre-tightening member, the pre-tightening member is adjustably connected with the axle end support and the connecting assembly. The application can make the bearing of the shaft system not bear axial load or reduce the axial load acting on the bearing of the shaft system, and improve the service life of the bearing.

Seat structure and vehicle

ActiveCN224714872USimple structureSmooth turning action
The application relates to the technical field of vehicle seats, and provides a seat structure and a vehicle. The seat structure comprises a mounting seat, a backrest rotatably arranged on the mounting seat, and a torsion rod arranged between the mounting seat and the backrest; the mounting seat is used for being connected with a vehicle body, the torsion rod is arranged along the width direction of the backrest, one end of the torsion rod is connected with the backrest, the other end of the torsion rod is connected with the mounting seat after penetrating through the backrest, and the torsion rod has a pre-tightening force for driving the backrest to overturn forward. According to the application, the torsion rod has the pre-tightening force for driving the backrest to overturn forward, when the inclination angle of the backrest is adjusted, the backrest is always helped to be attached to the back of a passenger under the driving of the torsion rod, so that the passenger can conveniently adjust the backrest to a comfortable inclination angle, the seat posture adjustment convenience is improved, and the vehicle quality is improved. Moreover, the torsion rod is adopted to provide the pre-tightening force for driving the backrest to overturn forward, the pre-tightening force is more stable in release, and the structure of the torsion rod is simple, so that the design and implementation are facilitated.
