Description
Technical field
The invention belongs to Design of Mechanical Structure field, be specifically related to the improvement to a kind of universal joint movement mechanism.
Background technology
The present invention is different from traditional universal-joint, forked element or X conn, need utilize the rolling characteristics of this mechanism to keep direction and the air-flow performance of installation shaft to match, and domesticly never designs before this this kind of rolling type universal joint movement mechanism.Applicant not discovery feature, the similar universal joint movement mechanism of principle in the patent documentation having retrieved.
In European patent GB586271, disclosed a kind of in process is dropped a bomb in underriding for improving the device of the aircraft ken, be cam link rocker arm body, its function and principle all have very large difference with the present invention.
In Chinese patent CN02823572.X, disclose a kind of tunable arrangement with Hooke's coupling, utilized two lockable ball pivots to realize universal movement, firmly fixed and put in place for realizing temporarily.
Domestic more Universal joint structure patent is for vehicle transmission.In Chinese patent CN200480017182.8, disclose a kind of Hooke's coupling, on this Hooke's coupling, be provided with drag loading for the oscillating motion of spider arm maximum and along with from then on leaving the resistance applying mechanism diminishing gradually in the time that pivot angle is 0 °, to suppress the variation of the transmitting torque between input and output shaft, this Hooke's coupling is used on auto steerer, can improves and handle sense.
The swing fuel filler pipe of KC-135A is by waving and realize side travel around vertical axis, and the section of fuel filler pipe can not can match by gentle fluidity.This universal joint movement mechanism is similar with KC-10A aircraft universal joint mechanism, rotate by making fuel filler pipe installation shaft the side travel of realizing fuel filler pipe end around major axis, the direction of installation shaft keeps the section of fuel filler pipe and its air-flow performance to match, by comparison, this programme anufacturability and maintainability are better, also have many places to improve on local detail.
Summary of the invention
Object of the present invention: task of the present invention is to make the direction of fuel filler pipe installation shaft keep the section of fuel filler pipe and its air-flow performance to match, and all can realize control in operating envelope limit range.Its objective is and make fuel filler pipe flexible motion in the control envelope curve of aircraft, guarantee aircraft refuelling pipe docks and disengagement with refueled aircraft socket.
Technical scheme of the present invention is:
A kind of rolling type universal joint movement mechanism, it is characterized in that, by fixed bearing, pressurized strut, rocker-arm link mechanism, sidewinder axle, sidewinder shaft sleeve, sidewinder fork ear, fuel filler pipe connects bearing seven part compositions, wherein, sidewindering shaft sleeve is made up of three parts, comprise front end cover, cylindrical shell and rear side housing, the annexation of said modules is: fixed bearing and pressurized strut, rocking arm and sidewinder shaft sleeve and connect by articulated manner, pressurized strut adopts articulated manner to be connected with rocking arm, connecting rod with sidewinder shaft sleeve and be connected by articulated manner, sidewindering axle supports sidewindering in shaft sleeve by bearing and lining, sidewinder axle through sidewindering shaft sleeve rear side housing and sidewindering fork ear by bolt tightening, sidewindering fork ear is connected bearing with fuel filler pipe and connects by articulated manner.
Described fixed bearing is made up of pressurized strut fixed bearing, rocking arm fixed bearing, sleeve fixed bearing three parts.
Described length of connecting rod is adjustable.
Described cylindrical shell adopts bolt tightening with sidewindering axle front and rear cover, and front end cover is enclosed construction, and rear side housing leaves and sidewinders shaft through-hole.
Described connecting rod is connected by articulated manner with the front end cover that sidewinders shaft sleeve.
Beneficial effect of the present invention is: the present invention has filled up domestic prior art blank.Its advantage is that groundwork is simple, and Installation and Debugging are quick, and maintenance and repair is convenient, can meet the operating needs of fuel filler pipe flexible motion in the control envelope curve of aircraft.This universal joint movement mechanism uses general conventional aeronautical material to make, and installs and adjusts simply, has greatly saved manufacturing cost.
