Tail reduction receiver and heavy duty tail reducer

Abstract

The invention provides a tail reducer casing and a heavy-duty tail reducer. The tail reducer receiver includes the tail reducer main receiver, the tail reducer input receiver and multiple pairs of mounting legs. Wherein, the tail reduction main casing and the tail reduction input casing are integrally structured, a part of the tail reduction input casing is located inside the tail reduction main casing, and at least a part of the tail reduction input casing is located inside the tail reduction main casing. Hollow structure. The tail reduction casing also includes a plurality of reinforcement plates, each reinforcement plate is arranged between the same side of the two mounting legs of the same pair and the bottom of the tail reduction main case, and a plurality of reinforcement plates of the tail reduction main case are provided with reducing Heavy holes, the outermost reinforcing plate is provided with special-shaped lightening holes. Through the above design, the present invention changes the existing independent design of the tail reduction main casing and the tail reduction input casing into an integrated design, which can simplify the structure of the equipment and reduce the weight of the equipment. Furthermore, the tail reduction casing proposed by the present invention can not only reduce the weight of the equipment but also ensure the load-bearing strength through the design of the weight reduction hole.

Description

technical field [0001] The invention relates to the technical field of helicopter reducers, in particular to a tail reduction casing and a heavy-duty tail reducer. Background technique [0002] The tail reducer casing is an important part of the tail reducer of the helicopter. The existing tail reduction casing mainly includes two parts, the tail reduction input casing and the tail reduction main casing. These two parts belong to two mutually independent casings, and the tail reduction input casing is all solid in its circumferential direction structure. Therefore, the weight of the existing tail reducing casing and the tail reducing casing are heavy, complex in structure, difficult to process and short in life. In addition, the reinforcing plate of the main load-bearing part of the existing tail reducer casing cannot be provided with a weight-reducing hole, or once the weight-reducing hole is provided, the bearing capacity of the load-bearing part will be affected.
