A locking mechanism is provided including a proximal component including a distal end including a first spanning distance and a gap disposed between a material of the distal end defining the first spanning distance. A distal component is rotationally coupled with the proximal portion. The distal component includes a cavity including a distal end, the cavity rotationally coupled with the distal end of the proximal component. The cavity includes a second spanning distance of the distal end of the cavity. A rotation of the proximal component with respect to the distal component, or the distal component with respect to the proximal component, is configured to align a direction of the first spanning distance with a direction of the second spanning distance and diminish the gap of the proximal component.

The application provides a wind turbine blade locking device, which is arranged in a wind turbine and connected with a hub of a blade to lock the hub. The blade locking device comprises a locking mechanism and a connecting mechanism. The locking mechanism comprises a gear ring and a gear rack. The gear ring is fixedly connected with the hub. An inner ring of the gear ring is provided with an inner gear groove. The gear rack is engaged with the inner gear groove. The gear rack is connected with one end of the connecting mechanism. The other end of the connecting mechanism is used for fixedly connecting in the wind turbine. The gear ring and the gear rack are engaged to lock the hub. The locking mechanism and the wind turbine are fixed through the connecting mechanism. The locking structure is simple, the engaged locking mode is stable, the rotation of the hub can be effectively limited during the maintenance of the blade, safe working conditions are provided for the maintenance work, the overall device meets the internal installation requirements of the wind turbine, and the connection relationship is reasonable and can effectively transmit the locking force.

The utility model relates to the technical field of bolts, in particular to a quick-assembly type anti-skid self-locking hub bolt for an automobile. The utility model relates to an automobile quick-assembly type anti-skidding self-locking hub bolt which comprises a bolt body. According to the utility model, the conical rubber anti-skid sleeve is sleeved on the outer ring of the screw rod of the bolt, then the conical metal sleeve is sleeved on the outer ring of the conical rubber anti-skid sleeve, and then the connecting column penetrates through the through hole of the connecting ring and the insertion hole of the bolt, so that the connecting column is stably fixed in the insertion hole of the bolt by matching with the magnetic attraction force of the magnetic block; in addition, after the conical rubber anti-skid sleeve, the first anti-skid knurl and the second anti-skid knurl lose efficacy due to abrasion, a worker can conveniently and rapidly move the pressing ring and the conical metal sleeve downwards to be separated from the bolt through the first pull groove; and then a worker can conveniently and quickly move the connecting ring together with the conical rubber anti-skid sleeve downwards to be separated from the bolt through the second pull groove, so that the effect of quickly replacing quick-wear parts is achieved.

A locking hub system for locking a wheel hub of a vehicle to an axle is provided. The system has a locking ring that may be moved between locked and unlocked configurations. When in the locked configuration, the hub is in a rotationally fixed position relative to the axle on which the hub is mounted. With the hub locked to the axle, the wheel will not rotate and the vehicle thus cannot be moved. When in the unlocked configuration, the hub can rotate freely about the axle, thereby allowing movement of the vehicle. The hub is fastened to the axle using a threaded nut. The threaded nut is retained on the axle by a nut retainer having inwardly facing tangs that are positioned within a groove around the axle.

A locking mechanism is provided including a proximal component including a distal end including a first spanning distance and a gap disposed between a material of the distal end defining the first spanning distance. A distal component is rotationally coupled with the proximal portion. The distal component includes a cavity including a distal end, the cavity rotationally coupled with the distal end of the proximal component. The cavity includes a second spanning distance of the distal end of the cavity. A rotation of the proximal component with respect to the distal component, or the distal component with respect to the proximal component, is configured to align a direction of the first spanning distance with a direction of the second spanning distance and diminish the gap of the proximal component.

The utility model relates to a parking self-locking hub motor, which comprises a hub, a stator, a rotor, an electromagnetic lock and a motor shaft, the stator, the rotor, the electromagnetic lock and the motor shaft are positioned in the hub, the stator is fixedly sleeved on the motor shaft, the rotor is sleeved on the outer side of the stator, a hub cover is integrally formed on the side surface of the hub, the hub cover and the electromagnetic lock are sleeved on the motor shaft, and the electromagnetic lock is connected with the hub cover.
