Abstract
The utility model relates to a kind of accessory drive gearbox class product total flows to test with classification flow-limiting nozzle, the flow-limiting nozzle is cirque structure, including flow-limiting nozzle ontology, it is mounted on the oil circuit of accessory drive gearbox, the flow-limiting nozzle ontology is multiple, its outer diameter is identical, and internal diameter is respectively design value, is greater than design value and is less than design value.When the utility model is used, according to demand, satisfactory flow-limiting nozzle is directly changed after removing if flow value is unqualified, avoid the process for needing machine to add in former mode and machine add during waiting time.
Description
Technical field
The utility model relates to a kind of accessory drive gearbox class product total flows to test with classification flow-limiting nozzle.
Background technique
Aircraft or engine accessory power rating casing class product are when carrying out total flow test, if flow value is unqualified, need pair
Test(ing) medium entrance flow-limiting nozzle carries out reaming.Flow-limiting nozzle is restored to assemble after reaming and re-starts test, if total flow is still
It is so unqualified, then above-mentioned work is repeated, until qualified.The even accessory drive gearbox class product of identical type, due to casting
Cause with machining tolerance, cast inside oil circuit and machine add the pore size of nozzle opening not exactly the same, produce so as to cause every
The state of product total flow is inconsistent, so flow-limiting nozzle pore size required for every casing class product is different.It is testing at present
In the process, total flow is tested and unqualified lead to flow-limiting nozzle disassembly repeatedly, reaming, restores a series of activities such as assembly, serious shadow
Ring working efficiency；And broaching equipment, testing equipment are recycled, it results in waste of resources.
Summary of the invention
The purpose of the utility model is to provide a kind of accessory drive gearbox class product total flows to test with classification flow-limiting nozzle, Ke Yishi
Accessory drive gearbox class product total flow test efficiency is now improved, experimentation cost is saved.
The particular content of the utility model is that the product total flow test of accessory drive gearbox class is circular ring shape knot with classification flow-limiting nozzle
Structure, including flow-limiting nozzle ontology, are mounted on the oil circuit of accessory drive gearbox, the flow-limiting nozzle ontology be it is multiple, outer diameter is identical, interior
Diameter is respectively design value, is greater than design value and is less than design value, and the internal diameter is more larger and smaller than the flow-limiting nozzle of design value
A, internal diameter presses gradient fractionation, and the gradient is 0.05mm.
Each flow-limiting nozzle is distinguished by tinting.
The utility model is multistage to its flow-limiting nozzle oil inlet Ф D points, manufactures and designs multiple flow-limiting nozzles, gradient is
0.05, in addition to Ф D, flow-limiting nozzle others size and actual product are completely the same, and each flow-limiting nozzle is distinguished by tinting,
Prevent misloading.When the utility model is used, directly being changed according to demand, after removing satisfactory if flow value is unqualified
Flow-limiting nozzle, avoid the process for needing machine to add in former mode and machine add during waiting time, proved by actual use,
The utility model can make to test total period each time and improve 60%, save into 2580 yuan of book.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side view of Fig. 1.
Specific embodiment
As shown, the product total flow test of accessory drive gearbox class is cirque structure, including flow-limiting nozzle with classification flow-limiting nozzle
Ontology 1, is mounted on the oil circuit of accessory drive gearbox, the flow-limiting nozzle ontology 1 be it is multiple, outer diameter is identical, internal diameter be respectively set
Evaluation, be greater than design value and be less than design value, the internal diameter larger and smaller than design value flow-limiting nozzle be it is multiple, internal diameter is pressed
Gradient fractionation, the gradient are 0.05mm.
Each flow-limiting nozzle is distinguished by tinting.
Claims (2)
