Abstract
A high gear box for aviation oil pump experiments comprises a box body (1) and is characterized in that the box body (1) is composed of an upper box body(6) and a lower box body (7), the box body(1) is provided with an input shaft (2), an output shaft (3), a low-speed rack wheel (4) and a high-speed pinion (5), wherein the low-speed rack wheel (4) is installed on the input shaft (2), one end of the input shaft (2) protrudes out of the box body (1) to be connected with a driving motor, the high-speed pinion (5) is installed on the output shaft (3) and meshed with the low-speed rack wheel (4), and one end of the output shaft (3) protrudes out of the box body (1) to be connected with the input end of an aviation oil pump. The high gear box for aviation oil pump experiments adopts an overdrive gear box in an occasion requiring high-speed input for the first time, provides required equipment for experiments of the overdrive gear box, has simple structure, is convenient to manufacture and has reliable and stable performance.
Description
Technical field
The utility model relates to a kind of mechanical transmission, especially a kind of test speeder, specifically a kind of aero oil pump testing high-speed gear box.
Background technique
At present, for the equipment under the rugged environment such as aviation field high speed, never good method is tested check.All be to test by the mode that simulation is derived for a long time, test result has only reference value not have trustworthy True Data, causes the waste of manpower, financial resources.
Because the rotating speed of aviation oil pump is fine, the prior motor output speed can't reach corresponding requirement, this just causes the test of oil pump generally can't carry out the simulation of true environment for a long time, and therefore developing a kind of this type of device that needs high rotating speed input that is applicable to is the key of solution air speed oil pump performance check.
Summary of the invention
The purpose of this utility model is at existing aviation oil pump owing to there is not the problem of relevant high-speed driving equipment, designs a kind of aero oil pump testing high-speed gear box that can satisfy high rotating speed output.
The technical solution of the utility model is:
A kind of aero oil pump testing high-speed gear box, comprise casing 1, it is characterized in that described casing 1 is made up of upper box 6 and lower box 7, in described casing 1, be provided with input shaft 2, output shaft 3, low speed gearwheel 4 and high speed small gear 5, described low speed gear 4 is installed on the input shaft 2, one end of output shaft 2 stretches out outside the casing 1 and links to each other with drive motor, described high speed small gear 5 is installed on the output shaft 3 and with described low speed gearwheel 4 and is meshed, and an end of output shaft 3 stretches out outside the casing 1 and links to each other with the input end of aviation oil pump.
The two ends of described output shaft 3 are bearing in respectively on the corresponding high-speed bearing 8, and described high-speed bearing 8 is installed on the casing 1.
The beneficial effects of the utility model:
1. the utility model is used for step-up gear the needs occasion of input at a high speed first, and the experiment of kind equipment provides necessary equipment for this reason, and it has simple in structure, and easily manufactured advantage is stable and reliable for performance.
2. the utility model can reduce the test period of aviation oil pump economical, easily.
3. of the present utility model succeeding in developing the lead time that helps shortening the aviation oil pump.
4. can react the use of aviation oil pump, maintenance period really, improve the reliability that the aviation oil pump uses.
5. the utility model helps obtaining reliable True Data, saves test procedure, shortens the lead time.

Fig. 2 is the utility model plan structure schematic representation.
Fig. 3 is a side-looking structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Figure 1-3.
A kind of aero oil pump testing high-speed gear box, comprise casing 1, described casing 1 is made up of upper box 6 and lower box 7, turn round not as Fig. 1, in described casing 1, be provided with input shaft 2, output shaft 3, low speed gearwheel 4 and high speed small gear 5, shown in Fig. 2,3, described low speed gear 4 is installed on the input shaft 2, one end of output shaft 2 stretches out outside the casing 1 and links to each other with drive motor, described high speed small gear 5 is installed on the output shaft 3 and with described low speed gearwheel 4 and is meshed, and an end of output shaft 3 stretches out outside the casing 1 and links to each other with the input end of aviation oil pump.The two ends of described output shaft 3 are bearing in respectively on the corresponding high-speed bearing 8, and described high-speed bearing 8 is installed on the casing 1.
Prime mover (as motor) reaches actual use through the steady speedup of gear-box and uses output speed from input end input high-speed gear box, connects sensor carry aviation oil pump at output terminal, obtains genuine and believable test data.Reached aforementioned goal of the invention effectively through the utility model.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
