Technical field
The utility model relates to a kind of dynamic balancing tooling, and 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
