Description
Technical field
The present invention relates to a kind of dynamic balancing tooling, especially a kind of cantilever rotor whole dynamic balance frock, is applicable to the whole dynamic balance of engine cantilever core engine rotor.
Background technology
Cantilever rotor refers to that one end is suspended state, passes through to rotate to produce or the parts of transmission power at work.At work, because bracketed part is long, weight is large, the rotating speed of rotor is high, therefore also higher to its requirement for dynamic balance for some cantilever rotor.As in certain aeromotor, belonging to it, core engine working rotor state is cantilever position, the weight of cantilever and length are than large, maximum core engine rotor bracketed part is 203mm and 96mm with the length of support mounting portion, weight is 13.5Kg and 1.5Kg, and namely length ratio is about 2.1, weight ratio is about 9, and its dynamic balance accuracy requires high, maximum allowable transient equilibrium value requires within 10.8gmm, close to the limit of the dynamic balance accuracy grade of rotor own.At the enterprising action balance of existing belt drives dynamic balancing machine, due to the elastic instability tension force of belt itself, rotor is operated extremely unstable, cause dynamic balance stability poor, poor repeatability; Again due to the restriction of core engine rotor structure, lack for belt drives position, therefore whole dynamic balance cannot be carried out, first will carry out transient equilibrium to rotatable parts, the assembling of rotor global facility is carried out in qualified rear decomposition again, cannot measure transient equilibrium again after the assembling of rotor entirety, but be directly used in installation, facts have proved, decompose and reassemble in process and may occur that irregular transient equilibrium value at double becomes large situation, cause multiple stage complete machine oscillation large and cannot use.
For the situation cannot carrying out whole dynamic balance on existing equilibrator to cantilever core engine rotor, propose and drive cantilever core engine rotor turns by introducing high-pressure air source, substitute the method for existing belt-type transmission, one can solve and cannot carry out dynamically balanced problem to cantilever rotor entirety, the dynamic balance stability simultaneously elastic instability of belt itself can also being avoided to cause is poor, the shortcoming of poor repeatability.Meanwhile, high-pressure air source drives cantilever core engine rotor, also close with the operating mode of cantilever rotor work, therefore can ensure stability in use and the reliability of complete machine.Because this dynamic balance method belongs to new technology, therefore need newly to design a kind of dynamic balancing tooling, cantilever rotor can be driven to rotate by high-pressure air source, better simulate actual applying working condition simultaneously.
Summary of the invention
The object of this invention is to provide a kind of cantilever rotor whole dynamic balance frock, the whole dynamic balance to cantilever rotor can be realized, and avoid the impact of dynamic balancing machine belt flexibility in existing dynamic balance method, and simulation carries out transient equilibrium when real work operating mode.
Concrete technical scheme of the present invention is, cantilever rotor whole dynamic balance frock comprises rotor field spider, stator support, pneumatic ring, described rotor field spider is fixedly connected on the bearing shell of left and right rocker of dynamic balancing machine, rotor field spider is provided with the mounting structure of cantilever rotor, treat that dynamically balanced cantilever rotor to be arranged on rotor field spider by described mounting structure and can around the axis rotation of cantilever rotor itself, stator support is fixed on the guide rail of dynamic balancing machine, stator support be provided with stator mounting structure and be installed with the quiet parts of cantilever core engine, rotor field spider is also provided with locating piece, stator support is close to locating piece when mounted to ensure that quiet parts are consistent with when working with the position between cantilever rotor after installing, stator support is also provided with pneumatic ring, and described pneumatic ring inside is provided with gas circuit, and one end communicates with high-pressure air source, and the other end is provided with air outlet, and described air outlet is multiple and arranges symmetrically and evenly, the vertical and cantilever rotor blade surface in the direction of air outlet.
The quantity of described air outlet is identical with the quantity of cantilever rotor blade.Mounting structure on rotor field spider and cantilever rotor mounting structure is operationally identical; Mounting structure on stator support comprises stationary half and movable semi-ring, and stator part to be arranged in stationary half and to be fixed by movable semi-ring; Pneumatic controller is provided with between pneumatic ring and high-pressure air source.
Rotor field spider of the present invention is installed on the bearing shell of dynamic balancing machine left and right rocker, for installing cantilever rotor and carrying out connecting test with dynamic balancing machine; Stator support installing is on the guide rail of dynamic balancing machine, and for supporting stator, isolation turns stator and installation supports pneumatic ring; Limited block carries out axial limiting to stator support, indirect spacing stator part, guarantees to turn, keep a safe distance when transient equilibrium between stator.Pneumatic ring is loaded on stator support, provides high drive wind regime to rotor.Carry briquetting with bearing shell after rotor field spider assembling evenly to fix between frock and bearing shell with homeostasis moment, left and right rocker is connected.By simulated engine mounting structure form, utilize mounting structure that cantilever rotor is installed, by dynamic balance running, the real vibration values measured rotor installation fulcrum on the engine and transmit.The actual installation structure of simulated engine rotor of the present invention designs, coordinate pneumatic driving transient equilibrium new technology, change outer for the cantilever of relative dynamic balancing machine barycenter into interior barycenter, eliminate due to belt gear and the variable effect repeating the irregular transient equilibrium value that the uncertain factors such as dismounting cause, after ensureing that rotor whole dynamic balance reaches designing requirement, do not need to split, be directly used in installation, to improve stability in use and the reliability of product.
