Description
Technical field
It is the shaft drive that moves about and support that the utility model relates to an end, is particularly suitable for the elevation axis system as longitude and latitude view of working under vibration and impact condition and photoelectricity stabilized platform, belongs to stable equilibrium's technical field in the aircraft.
Background technique
In theodolite and the photoelectricity stabilized platform, elevation axis as shaft drive is that normally two ends are respectively fixed support and the drive line of the support of moving about, the drive line that is called for short " fix-moving about ", also having a kind of is the drive line that two ends are respectively fixed support, is called for short the drive line of " two ends are fixed ".Its supporting form of the drive line of " fix-moving about " is simple in structure, effectively the compensation work temperature variation causes the axial dimension between turning axle and the supporting base to change, but under axial impact that transmission shaft is arranged and vibration environment, the axial stiffness of drive line is relatively poor, there are wearing and tearing in the matching part of bearing and supporting base of end of moving about, vibrate phenomenon such as increasing, this phenomenon can influence the drive line precision, and shortens the working life of drive line." two ends are fixed " though its supporting form of drive line can improve axial impact resistance and to the vibration adaptive capacity to environment, but can't the compensation work temperature variation cause the axial dimension between turning axle and the supporting base to change, can cause the clamping stagnation or the precision forfeiture of drive line.
Summary of the invention
The purpose of this utility model is, overcome the shortcoming of prior art, an a kind of end that provides is the shaft drive that moves about and support, its moved end, drive line middle reaches has the elasticity pre-pressing structure, overcome the problem of " fix-moving about " supporting form bad adaptability under impact, vibration environment of drive line, simultaneously still keep this supporting form can compensate, cause the function that axial dimension changes between transmission shaft and the supporting base because of temperature change.
The technical solution of the utility model is: an end is the shaft drive that moves about and support, and it comprises that supporting base and two ends have the cavity of turning axle; This cavity one side is the fixed end turning axle, and by the fixed end roller bearings, this fixed end rolling bearing has fixed end outer ring pressing plate and fixed end inner ring pressing plate; The cavity opposite side is the end turning axle that moves about, by the end roller bearings of moving about; The fixed end turning axle and the end turning axle dead in line of moving about; The end rolling bearing that moves about also has move about the end outer elastic pressing plate and the inboard spring bearer plate of end that moves about that is used for axial and the radial tightening and the location of the end turning axle that moves about, and the end inner ring stationary platen that moves about.
Further technological scheme is on the such scheme basis:
A described end is the shaft drive that moves about and support, and its end outer elastic pressing plate that moves about is an annular pressing plate with the inboard spring bearer plate of end that moves about; The end outer elastic of moving about pressing plate inner ring has equally distributed Elastic Teeth, and pressing plate is evenly distributed with fixed hole on the plane; Move about and hold the inner ring of inboard spring bearer plate that equally distributed Elastic Teeth is arranged; Pressing plate is evenly distributed with fixed hole on the plane.
A described end is the shaft drive that moves about and support, and the Elastic Teeth of its end outer elastic pressing plate that moves about is with the height that Elastic Teeth is crooked to the same in-plane of pressing plate and projection is identical of the inboard spring bearer plate of end that moves about.
A described end is the shaft drive that moves about and support, and its Elastic Teeth is protruding " U " shape, and roller seating space is recessed " U " shape.
A described end is the shaft drive that moves about and support, and a kind of in light, electricity or the observing and controlling member is installed in its cavity, or two kinds of combinations, or three kinds of combinations.
Principle of the present utility model and good effect are: the fixed end rolling bearing has limited fixed end rolling bearing moving with respect to supporting base and turning axle on the axial direction of axle system by the shaft shoulder, the step on the supporting base, fixed end outer ring pressing plate and fixed end inner ring pressing plate on the fixed end turning axle; Move about the end rolling bearing by the shaft shoulder on the turning axle and the end inner ring stationary platen that moves about, having limited move about the end rolling bearing with respect to turning axle axle system axially on move.The described end outer elastic pressing plate that moves about, the inboard spring bearer plate of end that moves about all adopt the multiple tooth structural type of annular inner ring, can make pressing plate axle system axially on have elasticity.The utility model since axle system axially on, move about and hold the both direction of rolling bearing all to be subjected to the spacing and pretension of effective elasticity, improved the axial rigidity of axle system, reduce axle and tied up to wearing and tearing and vibration under axial impact, the vibration environment, strengthened the adaptability under impact, the vibration environment of spool tying up to of " fix-moving about " supporting form.Simultaneously, because what adopt is the spacing and pretension of elasticity, when temperature change causes in the axial direction turning axle relatively and supporting base need elongate or shorten the time, the end rolling bearing that moves about still can overcome the end outer elastic pressing plate that moves about, or move about and hold the impacting force of inboard spring bearer plate to move about, can avoid axle is clamping stagnation.
In a word, the utility model has been eliminated the problem of " fix-moving about " supporting form bad adaptability under impact, vibration environment, kept simultaneously " fix-moving about " supporting form effectively the compensation work temperature variation cause the advantage that axial dimension changes between turning axle and the supporting base, also has compact structure, manufacturing process is simple, and outstanding advantage is installed and easy to maintenance etc.
