Unmanned helicopter tail transmission structure

Abstract

The invention discloses a tail transmission structure of an unmanned helicopter, belongs to the technical field of transmission devices of unmanned helicopters, and solves the problems that a tail transmission line of the unmanned helicopter is long, a tail transmission shaft is easy to deform greatly in the transmission process and can vibrate violently, and meanwhile, the tail transmission shaft is not easy to deform in the vibration process. The tail transmission structure comprises a deep groove ball bearing, a tail transmission shaft support, a tail transmission shaft positioning sleeve, a tail transmission shaft and a tail transmission shaft supporting cylinder. The tail transmission shaft is coaxially installed in the tail transmission shaft supporting cylinder through a tail transmission shaft support. The more than two tail transmission shaft supports are uniformly distributed along the length direction of the tail transmission shaft; and each tail transmission shaft support is coaxially sleeved on the tail transmission shaft through a deep groove ball bearing and a tail transmission shaft positioning sleeve. Deformation of the tail transmission shaft in the long-distance transmission process can be reduced, and vibration of the tail transmission shaft is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of transmission devices of unmanned helicopters, and in particular relates to a tail transmission structure of unmanned helicopters. Background technique [0002] UAV helicopters are developing rapidly, and they are more and more widely used in surveying and mapping, rescue and fire fighting. The transmission of the tail of the UAV is very important, and the transmission mode of the tail of the UAV is also constantly developing; but for large-scale helicopters For unmanned helicopters, the unmanned helicopter has a long tail transmission route, and the tail transmission shaft is prone to large deformation during the transmission process, and the tail transmission shaft will produce violent vibration. At the same time, during the vibration process of the tail transmission shaft, the tail transmission shaft The inner ring of the bearing is particularly prone to dislocation, which in turn affects the transmissi...

[0002] UAV helicopters are developing rapidly, and are more and more widely used in surveying and mapping, rescue and fire fighting. The transmission of the tail of the UAV is very important, and the transmission mode of the tail of the UAV is also constantly developing; For unmanned helicopters, the tail transmission line of unmanned helicopters is long, and the tail transmission shaft is prone to large deformation during the transmission process, and the tail transmission shaft will produce severe vibration. At the same time, during the vibration process of the tail transmission shaft, the tail transmission shaft The inner ring of the bearing is particularly prone to misalignment, which will affect the transmission stability of the tail drive shaft
