Abstract
The utility model relaters to a slewing bearing structure for an aircraft fuel system test turntable, which belongs to the technical field of aviation test machinery and is used for a ground simulation test. A slewing bearing is in a hollow structure. An inner ring of the slewing bearing is fixedly connected with an inner frame, and an outer ring of the slewing bearing is fixedly connected with an outer frame. The inner frame rotates along with the inner ring of the slewing bearing, and the slewing bearing is provided with a test article placing platform in a radial direction. The slewing bearing structure has the beneficial effects that 1, the slewing bearing structure can place various specifications of test articles; 2, the slewing bearing structure is simple and is conveniently operated; the slewing bearing structure has light weight and small energy consumption.
Description
Technical field
The utility model relates to a kind of Tumbler disc bearing structure for the aircraft fuel system test turntable, belongs to the Aviation Test field of mechanical technique, for ground simulation test.
Background technique
According to the regulation of aviation industry standard (HB7169-1995), aircraft fuel system, in development process, must carry out ground simulation test, the test turntable that required equipment is 2DOF.Domestic application is the gyro type turntable the most widely at present, and this class turntable is divided into interior housing two-part, and housing supports on the ground, and inside casing is supported on housing.Wherein housing is carried overall structure, the function such as inside casing is born the laying of testpieces, fixed, test.In this class turntable, housing connection of rotating part all adopts common radial bearing.Because two ends have adopted logical radial bearing, so just there is the very large limit in the space of inside casing installation testing part.The testpieces of big-length generally can't be arranged on inside casing.
Summary of the invention
In order to overcome the usage space limit that adopts common radial bearing, the utility model purpose is to provide a kind of large-scale turntable bearing of hollow.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of Tumbler disc bearing structure for the aircraft fuel system test turntable, this turntable bearing is hollow structure, and turntable bearing inner ring and inside casing are connected, and turntable bearing outer ring and housing are connected, inside casing rotates with the turntable bearing inner ring, and described turntable bearing radial direction is provided with the testpieces mounting table.
The beneficial effects of the utility model:
1, the utility model can be placed the testpieces of various model specifications.
2, the utility model is simple in structure, easy to operate.
3, the utility model weight is little, consumes energy little.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be elaborated:
A kind of Tumbler disc bearing structure for the aircraft fuel system test turntable, this turntable bearing is hollow structure, turntable bearing inner ring 1 is connected with inside casing 3, turntable bearing outer ring 2 is connected with housing 4, inside casing 3 rotates with turntable bearing inner ring 1, and described turntable bearing radial direction is provided with testpieces mounting table 6.Testpieces 5 can connect whole inside casing space.
Claims (1)
