Description
Technical field
The present invention relates to wind tunnel test field, specifically relate to a kind of roll angle adjusting gear.
Background technology
In wind tunnel test, the index under all angles of model is all needed to carry out accurate simulation test.By development for many years, the testing equipment of each test in wind tunnel test and technology are all progressively ripe, and each index can adopt existing technology and device to test.
Test for model roll angle is in wind tunnel test requisite one; The adjustment being directed to roll angle in existing techniques and methods achieves the goal by rotating model main strut, in process of the test, because roll angle is fixing, therefore carry out adjustment to need model to be pulled down rear rotation main strut and be loaded on model at every turn, and then test roll angle, if angle does not repeat adjustment to needs.Although therefore existing method can complete the adjustment to roll angle, need a large amount of time with artificial, very inconvenient.
Summary of the invention
The object of the invention is on the basis of existing technology, design a device that just can realize fast when not form removal type adjusting model roll angle.
For achieving the above object, the present invention adopts following technical scheme:
A kind of roll angle adjusting gear, comprising:
Transition piece, one end of transition piece is provided with connectivity port, and the other end is connected with rolling head, and be fixedly installed wobble shaft by bearing in rolling head, one end of wobble shaft is connected in transition piece,
Turbine and worm screw are connected on wobble shaft by key,
Main strut is connected on rolling head, and main strut is coaxial with wobble shaft.
In technique scheme, be provided with expansion sleeve between described wobble shaft and rolling head, the internal diameter of expansion sleeve is consistent with the external diameter of wobble shaft, and the external diameter of expansion sleeve is consistent with the internal diameter of rolling head.
In technique scheme, the front end of described expansion sleeve is provided with tensioner screw.
In technique scheme, be provided with two bearings between described rolling head and rolling post, two bearings are distributed in two surveys of turbine.
In technique scheme, described bearing is taper roll bearing.
In technique scheme, described wobble shaft is fixedly connected with transition piece, and is provided with set nut on the wobble shaft of junction.
In technique scheme, the front end of described rolling head and the side of main strut are provided with radome fairing.
In technique scheme, described cowling surface is streamlined.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: by device of the present invention, in wind tunnel test, the present invention is connected between main strut and fixed mount, main strut just can be driven to rotate by worm screw rotary turbine, thus band movable model carries out the adjustment of roll angle, model need not be removed the angle adjusting main strut more completely; Not only can realize the adjustment to roll angle fast by the present invention, and can also save time, raise the efficiency, by other supplementary meanss, the Adjustment precision of roll angle also and then be improved.
Structure of the present invention is simple, compact, provides rolling moment large, can self-locking, and employing can buy part, is easy to manufacture, and conveniently installs, simple to operate.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present invention;
Wherein: 1 is transition piece, 2 is set nuts, and 3 is bearings, and 4 is rolling heads, and 5 is keys, and 6 is worm gears, and 7 is worm screws, and 8 is expansion sleeves, and 9 is wobble shafts, and 10 is radome fairings, and 11 is expansion sleeve screws, and 12 is main struts.
Embodiment
As shown in Figure 1, the present invention includes transition piece, set nut, bearing, rolling head, key, worm gear, worm screw, expansion sleeve, wobble shaft, radome fairing, expansion sleeve screw, main strut.Transition piece front end is fixedly connected with back-up roller rotation member with rolling head, implementation model rolling, and wobble shaft is fixed on rolling head by bearing; Worm gear, worm screw connect wobble shaft by key, drive main strut to do rolling movement; Expansion sleeve inner and outer ring is connected with wobble shaft and rolling head respectively, by degree of tightness expansion sleeve screw, realizes the locking of wobble shaft and gets loose; Radome fairing is connected with rolling head, reduces flow field interference; Main strut is for installing the model needing to regulate roll attitude.
The driving of wobble shaft relies on worm couple to realize, and worm gear is connected in rotating shaft by key, installs a set of taper roll bearing respectively before and after rotating shaft, play supporting role to whole rotating shaft, and this supporting form can bear multi-load, and does not need the thermal expansion of compensating shaft.Rotating shaft tail end and transition piece junction are provided with double nut and lock, and provide bearing assemble precompression, ensure rotating shaft location, prevent play before and after worm gear.Because any roll angle of wobble shaft within the scope of 360 ° all needs to lock, select expansion sleeve to lock roll angle, be arranged between wobble shaft and rolling head, by the screw of degree of tightness expansion sleeve front end, make use of the principle of cone friction catch, realize the locking of wobble shaft and get loose.Expansion sleeve size is less, is suitable for the occasion of limited space.Radome fairing is installed in rolling head front end, adopts airflow design, reduces the interference of stream field.
In use, the rear end of transition piece can be connected with the angle of attack, yaw angle adjusting gear, and implementation model attitude angle changes, and front end is connected on main strut, and specific operation process is:
With screw by need to adjust connect between the parts of roll attitude and main strut fastening;
Unclamp expansion sleeve front end screw, drive wobble shaft by worm couple;
After adjusting to tram, fastening expansion sleeve front end screw;
Radome fairing is installed.
Four steps all need to stop carrying out when blowing at wind-tunnel above, adopt manually-operated mode.Certainly when conditions permit, also can adopt in wind tunnel test process, adopt automation equipment control to the automatic condition of roll angle and locking.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
