System, is improved that machinery driving efficiency, energy consumption be little, the feature such as simple in construction and stable performance, to improving domestic reducer
Quality and moment of torsion experiment etc. have important effect.
Summary of the invention
It is an object of the invention to provide the closed reality of planetary reducer that a kind of machinery driving efficiency is high, energy consumption is little
Test platform, to overcome the deficiency in the presence of prior art.
The present invention solves the technical scheme of its technical problem: a kind of closed laboratory table of planetary reducer, including
Motor, described motor connects output gear case, and output gear case divides two-way averagely to export moment of torsion, wherein leads up to universal joint shaft
Device, mounting seat export on the first decelerator, and another road connects hydraulic pressure loading device, mounting seat, the second decelerator；First, second
Decelerator is realized hydraulic tensioning by tensioner；First, second decelerator closed loop connects.
Described first decelerator and the second decelerator are connected by sprocket chain rail device, make first, second decelerator synchronize
Rotate and moment of torsion is identical.
Rotational speed and torque measuring instrument is connected between described hydraulic pressure loading device and the second decelerator.
Described hydraulic pressure loading device configuration hydraulic system and electric control system, so that hydraulic pressure loading device can provide constant pressure
Power.
Described motor uses frequency conversion motor.
Described first decelerator is to accompany examination decelerator or experiment decelerator, and described second decelerator is that experiment is slowed down
Device.
The invention has the beneficial effects as follows:
The present invention has that machinery driving efficiency is high, energy consumption is little and the feature such as stable performance.Solve domestic walking and elevator simultaneously
The bottleneck of decelerator experiment, is beneficial to improve reducer performance and quality, breaks domestic project machinery producer to external product
Dependence.
