Description
technical field:
the utility model relates to a kind of tulwar slide block variable-angle device based on gear-rack drive.
background technology:
tailspin is one of the most complicated state of flight of aircraft, be characterized in that the elevation angle is large, the radius of spin is little, turning rate is high, rate of sinking is fast, therefore when tailspin, the dynamic and manipulation of aircraft has a great difference with when usually flying, and as mishandling, may cause serious aircraft accident; In order to understand fully the essence of tailspin phenomenon, prevent aircraft from entering tailspin unexpectedly and guaranteeing to change safely, must further investigate the Tail chain of aircraft, due to tailspin move time, under aircraft is in large attack angle situation, effect flight force and moment is thereon nonlinear, and lengthwise movement is larger with the various sympathesiies of transverse movement, needs nonlinear mathematical model to describe; This brings very large difficulty in theory, and research is in the past subject to the restriction of experimental technique and computing technique, can only simplify mathematical model, is confined to the analysis of linear change; Current acquisition aircraft is vowing that around speed stablizing the comparatively ripe means of aerodynamic characteristic in rotary course is rotation balance test, the fundamental purpose of carrying out rotation balance test in wind-tunnel is exactly that rating model is when the different angle of attack and yaw angle, aerodynamic characteristic under wind axis makes constant speed rotation state with different rates, analysis and prediction for plane's trial spinning characteristic provides necessary Aerodynamic Coefficient, and the experiment of traditional rotary balance when becoming the angle of attack when carrying out manual operation difficulty very large, and equipment cost is high.
utility model content:
the purpose of this utility model is to provide a kind of tulwar slide block variable-angle device based on gear-rack drive.
above-mentioned object is realized by following technical scheme:
a kind of tulwar slide block variable-angle device based on gear-rack drive, its composition comprises: slide block, described slide block is connected with axle by screw A, described axle and guides mount pad adopt shaft hole matching to be connected, axle sleeve and roller guide described axle be equipped with, described roller guide and the leading edge of tulwar are fitted, and by pad adjustment contact distance, gear shaft is connected with described slide block by bearing, by set nut and lock washer, described gear shaft is fixed on described slide block, described tulwar is connected with tooth bar by screw B, described slide block is equipped with locking pin, described locking pin is equipped with spring, outside described locking pin, wing nut is housed.
the described tulwar slide block variable-angle device based on gear-rack drive, described tulwar is provided with groove, and described tooth bar is arranged in described groove; Described tulwar is provided with pin-and-hole, and described locking pin extend in described pin-and-hole under the pressure of described spring.
beneficial effect:
1. the utility model slide block remain silent inner side on, form guidance set by roller guide, axle, guides mount pad, axle sleeve, pad and screw, roller guide and tulwar medial surface are fitted, and play the guiding role in angle process; The symmetrical both sides of slide block opening, form driven unit by gear shaft, bearing, lock washer and set nut, gear shaft be arranged in tulwar groove tooth bar engage, play transmission dynamic action in angle process; Slide block opening side, forms self-locking assembly by wing nut, locking pin, spring, and locking pin is pressed into inside tulwar in pin-and-hole by spring pressure in not angle process, plays locking protective action; Wing nut on slide block is rotated clockwise, locking pin leaves the pin-and-hole on tulwar, by the gear shaft on ratchet wrench turning block mechanism driven unit, the tooth bar engaged transmission on gear shaft and tulwar, simultaneously guidance set auxiliary under realize the change in angle of attack of mechanism.
the utility model is a kind of for carrying out the special testing equipment of model aircraft rotation balance test system tulwar slide block angle in wind-tunnel, this mechanism has that compact conformation, processing charges are low, simple installation, the feature such as easy to use, is suitable for extensively promoting on rotary balance equipment.
