摘要： An inner ring for supporting variable-pitch blades of an axial compressor stator of a turbomachine includes two or more ring sectors, assembled to form the inner ring, each ring sector including plural housings for receiving a pivot axis of one of the blades. At each junction plane between the ends of two successive ring sectors, an assembly pin and a cavity for receiving the assembly pin are engaged. The assembly pin is fixed on one end one of the two successive ring sectors and the cavity is formed at the end of the other of the two successive ring sectors. The cavity receives the assembly pin with a mounting clearance allowing a mounting by sliding fit, and the assembly pin is made of a material having a coefficient of thermal expansion greater than a coefficient of thermal expansion of a material constituting the successive ring sectors.

摘要： The present application provides a fan light including a suspension bracket seat configured to fix and a fan light body connected to the suspension bracket seat. The suspension bracket seat is provided with a conductive threaded groove, the fan light body is provided with a conductive connection structure that can be matched and electrically connected with the threaded groove thread. The suspension bracket seat is further provided with a fixed structure configured to fix the fan light body to the suspension bracket seat. Through a cooperation of conductive connection structure and threaded groove, the fan light body can be electrically connected to the suspension bracket seat. When the fan needs to be reversed, the fixed structure can ensure that the fan light body is firmly fixed on the suspension bracket seat, thereby increasing safety, reducing a risk of accidental detachment or shaking, increasing flexibility and practicality.

摘要： An example axial pump for delivering liquid coolant to cool an electronic device comprises a conduit defining a flow path from an inlet of the conduit to an outlet of the conduit and an impeller in the conduit. The impeller is rotatable about an axis of rotation parallel to the flow path. The pump also has a motor stator configured to drive rotation of the impeller body about the axis of rotation. In addition, the pump comprises an adjustment mechanism coupling the impeller to the conduit. The adjustment mechanism is actuatable to cause translation of the impeller relative to the conduit. This may allow for adjustment of a clearance between a blade tip of a blade of the impeller and a wall of the conduit.

摘要： A tandem rotor disk apparatus may include a rotor disk body concentric about an axis. The tandem rotor disk apparatus may also include a first blade extending radially outward of the rotor disk body and a second blade extending radially outward of the rotor disk body. The first blade may be offset from the second blade in a direction parallel to the axis. The tandem rotor disk apparatus may be implemented in a gas turbine engine with no intervening stator vane stages disposed between the first blade and the second blade.
