CN103010450A - Synchronous rotating mechanism for left and right wings of transport helicopter - Google Patents

Abstract

The invention provides a synchronous rotating mechanism for left and right wings of a transport helicopter, through which the rotating angles of two wings are synchronous, thereby ensuring the flight stability of the transport helicopter and effectively avoiding flight accidents. The synchronous rotating mechanism is characterized by comprising a worm gear and a worm, wherein the worm is connected with a power drive device, the worm gear is respectively connected with drive shafts at the two ends of the worm gear, the drive shafts are respectively connected with a driving gear, the driving gears are respectively connected with a driven gear, and the driven gears are respectively connected with a wing propeller assembly.

Description

A kind of transport helicopter left and right synchronous rotary mechanism

Technical field

The present invention relates to the technical field of transport helicopter, be specially a kind of transport helicopter left and right synchronous rotary mechanism.

Background technology

In the transport helicopter of the two-shipper wing, wing not only will provide power for transport helicopter by wing slurry, but also to control the landing of transport helicopter, wing will change angle in flight course, reach the purpose of transport helicopter landing, the existing two-shipper wing is wanted the change of angle in flight course be that power system by separately provides power, this power transmission mode can make the anglec of rotation of the two-shipper wing asynchronous, thereby affected the stability of transport helicopter flight, also might cause aircraft accident.

Summary of the invention

For the problems referred to above, the invention provides a kind of transport helicopter left and right synchronous rotary mechanism, can make the anglec of rotation of the two-shipper wing synchronous, thereby guarantee the stability of transport helicopter flight, effectively avoided aircraft accident.

Its technical scheme is such: a kind of transport helicopter left and right synchronous rotary mechanism, it is characterized in that: it comprises worm gear, worm screw, described worm screw connects power drive, described worm gear connects respectively the transmission shaft at two ends, described transmission shaft connects respectively driving gear, described driving gear connects respectively ring gear, and described ring gear is connecting wing slurry assembly respectively.

In the said structure of the present invention, worm screw connects power drive, worm gear connects respectively the transmission shaft at two ends, transmission shaft connects respectively driving gear, and driving gear connects respectively ring gear, and transmission shaft is connecting wing slurry assembly respectively, because worm gear connects respectively the wing slurry assembly of left and right by the transmission shaft at two ends, realize the synchronous of the left and right anglec of rotation, thereby guaranteed the stability of transport helicopter flight, avoided causing aircraft accident.
