Abstract
The invention belongs to the technical field of airplane lubricating oil cooling systems and relates to a ventilation door drive mechanism for an airplane lubricating oil cooling system. The ventilation door drive mechanism for the airplane lubricating oil cooling system comprises an electric mechanism (2), supports (1), a rocker arm (3), an adjustable pull rod (4) and a ventilation door (5). According to the technical scheme, the ventilation door drive mechanism is maximally characterized in that the adjustable pull rod is adopted, the relative positions of all installed components can be finely adjusted, the installation tolerance is made up, and system reliability is improved. As another improvement, the triangular rocker arm (3) is adopted in the technical scheme, the power output direction can be changed, various possibilities are provided for the selection of the installation position of a power output device, and the space is effectively used.
Description
Technical field
The invention belongs to aircraft oil cooling system technical field, relate to the air door driving mechanism of a kind of aircraft oil cooling system.
Background technology
Aircraft upper wind door driving mechanism is generally adopted quadric chain, but the relative position of the general each component of double leval jib air door driving mechanism is unadjustable, and the installation requirement of mechanism is higher, therefore it is required that the machining accuracy of product is high. Once occur that bigger deviation may result in each component and cannot be attached to position, air door closed mode there may be bigger gap, or air door can not be opened to the aperture of regulation.
Summary of the invention
It is an object of the invention to: provide one can be effectively improved air door driving mechanism installation effectiveness, it is achieved the closed loop control of aperture opened by air door, it is possible to realize the axis direction of motor installation and the quadric chain of the uneven mounting arrangement of air door normal direction.
The technical scheme is that described air door driving mechanism includes: bearing 1, motor drive mechanism 2, rocking arm 3, adjustable drawbar 4 and air door 5;
Motor drive mechanism 2 is hinged on the bearing 1 of cooling system exhaustor, and rocking arm 3 is triangle with three fulcrums, and a fulcrum is hinged with bearing 1, and another fulcrum is hinged with the clutch end of motor drive mechanism 2;
Another of one end of adjustable drawbar 4 and rocking arm 3 is point articulated, and the other end is hinged on the bearing 1 of air door 5, and one end of air door 5 is hinged on the bearing 1 of cooling system;
The length of the position of three fulcrums and adjustable drawbar 4 on rocking arm 3, it is necessary to determine according to the movement locus of air door 5, the aperture of air door 5 and the shift length of motor drive mechanism 2;
The length of adjustable drawbar 4 can regulate.
Beneficial effects of the present invention has: owing in the technical program, design has length-adjustable pull bar, thus the present invention can realize installing after the fine setting of relative position between each parts, make up location tolerance, improve the reliability of system. Another provides the benefit that, the technical program have employed the rocking arm 3 of triangle, it is possible to achieve the change of power outbound course, thus the selection for PTO installation site provides multiple possibility, is effectively utilized space.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of the present invention;
In figure: 1-bearing, 2-motor drive mechanism, 3-rocking arm, 4-adjustable drawbar, 5-air door.
Detailed description of the invention
A kind of aircraft oil cooling system air door driving mechanism, including bearing 1, motor drive mechanism 2, rocking arm 3, adjustable drawbar 4, air door 5. Wherein, motor drive mechanism is arranged on the back of radiator exhaustor, motor drive mechanism linear movement output, built-in damper positions indicator, and when motor drive mechanism exports greatest length, motor drive mechanism stop motion, air door reaches maximum opening. This rocking arm is triangular member, it is possible to changed in the direction of the output of motor drive mechanism. Adjustable drawbar adjustable in length, it is made up of two oppositely oriented ear mount and a sleeve, one nut identical with ear mount rotation direction of each installation in the ear mount that sleeve two ends are corresponding, it is ensured that sleeve will not loosen due to vibration, thus ensureing that the length of pull bar will not change due to vibration. The ear mount at pull bar two ends has press-fited oscillating bearing, it is possible to the alignment error of compensation linkage. Axle of the air door is positioned at the side of air door, is connected with exhaustor by two supporting lugs. Air door is fixed together by four gusset plates and axle of the air door, and air door is in the closed position at ordinary times, and maximum open angle is 30 degree.
Consulting Fig. 1, after this air door driving mechanism installs, air door is closed, and the output shaft of motor drive mechanism is the shortest. When oil temperature overtemperature, it is necessary to when opening air door, motor drive mechanism 2 can receive an instruction, and motor drive mechanism, according to instruction, drives air door to open, and damper positions indicator can feed back one damper positions signal of output, it is achieved a closed loop control of air door open angle. Motor drive mechanism opens aperture according to what air door was determined in instruction, can make any one position that air door is maintained between 0 �㡫30 �� as required.
