Description

A TORQUE LOADING TEST DEVICE
Field of the Invention
The invention is related to a torque loading test device which enables simulation of the loads that come to the vehicles with wing drive system during flight within a test environment.
State of the Art
When the wing shaft is moved by means of the torque loading test device, the variable torque in proportion with the wing angle is loaded on the wing drive system. Therefore the system can be tested under the loads which can be encountered during flight. In the present state of the art, there are structures used for simulating the loads that come to the wing drive system during flight within a test environment.
In the present state of the art, the torque is provided by means of two frictional plates. One plate is stable and the other is mounted to the rotating section. In the prior art since torque is applied equally at each rotation angle, it was not appropriate for wind drive system tests. In addition to this when the wing drive system operates at high speeds and at high torques, it was unable to give response immediately. For this reason, the tests were made by means of performing an active control.
As a result of the researches made, patent application No CA2545705C is found. In said patent application, a system and a method which can make different loadings for the torque tests of the vehicle power transfer organs are disclosed. In this system two helical gears connected to the first shaft are adapted with two helical pinion gears connected to the second shaft. In the system within the present application the gears adapted with the pinion gears are not flat and a plurality of pinion gears is used.
As a result due to above mentioned disadvantages and the insufficiency of the current solutions in terms of the subject, an improvement in the relevant technical field is required. Aim of the Invention
The invention aims to solve the abovementioned disadvantages by means of being inspired form the current conditions.
The main aim of the invention is to simulate the loads that come to the vehicles with wing drive system during flight within a test environment by the torque loading test device.
Another aim of the invention is to enable torque application to the wing drive system with a determined angle, rotatable at right and left directions.
Another aim of the invention is to enable immediate response in case the wing drive system operates at high speeds and high torques by means of applying load to the wing drive shaft in a passive manner. Therefore the tests can be performed without making any active control.
In order to fulfill the abovementioned aims, the invention is a torque loading test device which enables simulation of the loads that come to the vehicles with wing drive system during flight within a test environment, characterized by comprising the following;
• pinion gear which receives rotary motion from the wing drive system,
• spur gear which is in contact with the pinion gear on the lower and upper parts of said pinion gear,
• compression springs which are located on the right and left sides of said spur gears, enables increasing the economic life of said torque loading test device by means of being compressed with preloading.
The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

Detailed Description of the Invention
In this detailed description, the preferred embodiments of the inventive torque loading test device (A) is described only for clarifying the subject matter.
The invention is a torque loading test device (A) which enables simulation of the loads that come to the vehicles with wing drive system during flight within a test environment, characterized in comprising the following; a pinion gear (1) which receives rotary motion from the wing drive system, a spur gear (2) which is in contact with pinion gear (1) on the lower and upper parts of said pinion gear (1), compression springs (6) which are located on right and left sides of said spur gears (2), enables increasing the economic life of said torque loading test device (A) by means of being compressed with preloading. In addition to this, it comprises a torque sensor (10) which transfers the rotary motion from the wing drive system to the pinion gear (1 ) and a shaft (7) which aligns the compression springs (6) by means of passing said compression springs (6). Also it comprises a spring seat (8) which enables connection of the compression springs (6) with the shaft (7) at right and left sides of the spur gears (2) and a rail (3) which enables their linear motion in a horizontal manner.
The inventive torque loading test device (A) comprises a roller bearing (4) which makes rotary motion by means of bearing with the pinion gear (1) and enables the linear motion of the spur gears (2) in the opposite direction and a rear wall (5) bearing with the roller bearing (4) in order to allow the pinion gear (1) performing only rotary motion. The torque force is created by means of the inventive torque loading test device in a manner such that, the horizontal force created by means of the compression springs (6) is transformed into the torque force by means of using the pinion gear (1 ) and the spur gear (2). The operating principle of the inventive torque loading test device (A) as shown with a perspective view in Figure 1 is as the following. The rotary motion which is transferred from the wing drive system to the torque loading test device (A) passes through the torque sensor (10), and is transferred to the pinion gear (1). The pinion gear (1) is located between two horizontal spur gears (2). The spur gears (2) are bearing on the rail (3) in an overlapping manner only for moving in a linear manner. Pinion gear (1) is bearing with the roller bearing (4) to the rear wall (4) only for performing rotary motion. The pinion gear (1) will try to rotate on the spur gears (2) by means of the rotary motion coming from the wing drive. Pinion gear (1) is bearing with the roller bearing (4) so that it will only perform rotary motion and the spur gears (2) will move linearly in an opposite direction to each other. On the right and left sides of the spur gears (2), compression springs (6), shafts (7) which will align the spring by means of passing through said compression springs (6) and spring seats (8) are disposed. Accordingly, the compressions springs (6) are trapped between the spur gear (2) and the side wall (9). While the spur gears (2) move in the opposite direction, they will create spring force by means of compressing the compression springs (6). The linear forces in the opposite direction created by means of the pinion gear (1 ) and the spur gear (2) will create torque force in the same direction on the pinion gear (1). In this manner, it is tested whether the system subject to testing reaches the required angles during required duration under the torque or not.
When the compression springs (6) are mounted to the inventive torque loading test device, equal preloading is given to both sides. This condition is obtained by means of using compression springs (6) which have similar features for right and left directions. In this manner, substantially similar torques are provided for both directions, thus the economic life of the torque loading device is extended by means of providing maximum 25% compression on the compression springs (6). The preloading amount is given in a manner such that at maximum rotation angles, minimum force is on the springs. The spur gears (2) will move in the opposite direction when the pinion gear (1) starts to rotate by means of the preloading process, while two compression springs (6) is compressed more, the other two compression springs (6) are released. Accordingly, the released compression springs will never be left without load and they will not create uncertainty and emptiness in the system. Also preloading will enable the rotary shaft (11) to be at the center when there is no motion on the torque loading test device (A). In the torque loading test device (A), the aim of disposing four compression springs (6) on the lower portion and the upper portion of the rotation axis and in a mutual manner is to prevent creating forces which will compel linear motion except the rotation on the pinion gear (1) by means of creating linear forces that occurred during rotation movement in the opposite direction. In this manner except the torque force created by the compression springs (6), the test system and the wing drive system will not be subjected to the other linear loads and thus a torque with high accuracy and certainty will be provided. As can be seen from Figure 2, all of the wings can be tested simultaneously by means of adding thereof into the main system from the torque loading test device (A) in proportion with the number of wing drive system to be tested.
Once the system is confirmed and authenticated, it is not required to make control during testing process; also its maintenance costs are reduced since no electronic equipment is required except the sensor and the reader which may be used optionally. The torque loading device will have a long economic life because the system substantially consists of mechanical parts and different forces to be created at high torques will be reduced by means of the configuration of the compression springs (6).
