Abstract

The invention discloses a driving device for a rotary model water tunnel test. The device comprises a motor, a frequency converter, a universal coupling, an upper transmission rod, a lower transmission rod, a transmission device, an upper bearing, a lower bearing, a gear, a turbine, an upper bottom plate, a lower bottom plate and a fixed rod; the motor is connected with and controlled by the frequency converter; the upper transmission rod and the lower transmission rod both pass through the fixed rod and are connected with the fixed rod respectively through the upper bearing and the lower bearing, the upper bearing and the lower bearing are fixedly installed in the fixed rod, the upper transmission rod is connected to an output shaft of the motor through a coupling, and the upper transmission rod drives the lower transmission rod through the transmission device; the fixed rod is fixedly connected with the upper bottom plate and the lower bottom plate; the gear is fixedly installed on the fixed rod and meshed with the turbine. The device disclosed by the invention can be used for realizing transmission of different transmission ratios of different surfaces of an input shaft and theoutput shaft and changing the included angle of the input shaft and the output shaft simultaneously in the process of transmission, and is suitable for test occasions where models such as water tunnels and wind tunnels need to be rotated and attack angles need changing.

Description

technical field [0001] The invention belongs to the technical field of fluid mechanics experiment equipment, in particular to a driving device for a rotating model water tunnel test. Background technique [0002] The rotating device can make the installation object rotate around its own body axis or other axes, and has a very wide range of applications in various fields such as industrial production and life. In the rotating model water tunnel test, it is necessary to drive the rotating model to rotate and make pitching motions. At present, the common rotating devices are mostly installed coaxially with the rotating body, or the axes are parallel, and the angle between the input and output axes cannot be flexibly adjusted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a driving device for rotating model water tunnel tests, which can provide stable torque to drive the model at different positions when the axis ...
