Description

Technical Field

[0001] The utility model relates to an air heat engine test instrument, in particular to a modular air heat engine test device. Background Art

[0002] In existing air heat engine experiments, a pointer-type torque meter is usually used to measure torque. When measuring torque, the operator changes the friction between the torque meter and the flywheel shaft of the air heat engine experimenter by adjusting the screw, and then reads the friction torque by checking the reading of the torque meter pointer on the dial.

[0003] However, in the actual experiment, there is a large error in measuring the friction torque using a pointer torque meter. The magnitude of the friction force cannot be controlled by manually adjusting the screw. During the rotation of the flywheel shaft, the pointer torque swings too much, resulting in a large reading error. If an external force is applied to intervene to stabilize the pointer reading, the accuracy of the reading will be affected, and a large error will also be generated. Therefore, a modular air heat engine experimental device is proposed. Utility Model Content

If the specific posture changes, the directional indication will also change accordingly.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figure 1-3 As shown in, a modular air heat engine experimental device comprises a platform 1, a heat engine 2 mounted on the platform 1, a heater for heating the heat engine 2, a flywheel 3 connected to the heat engine 2, a flywheel shaft 31 mounted on the flywheel 3, a measuring bracket 4 mounted on the platform 1, an arc-shaped measuring plate 41 mounted on the measuring bracket 4, and a torque meter 42 movably mounted on the measuring bracket 4; it is characterized in that it also comprises a dynamic torque meter assembly mounted on the platform 1, a synchronous pulley 1 32 mounted on the flywheel shaft 31, a synchronous pulley 2 33 mounted on the dynamic torque meter assembly and connected to the synchronous pulley 1 32 through a synchronous belt drive, and an electronic scale 1 6 mounted on the platform 1;

[0022] Through the setting of the dynamic torque meter assembly, the force of the flywheel shaft 31 is transmitted to the dynamic torque assembly through the synchronous pulley 1 32 and the synchronous pulley 2 33. When the transmission shaft 1 52 rotates, it drives the transmission gear 1 53 to rotate and drives the transmission gear 56 to transmit. The transmission gear 56 drives the transmission shaft 55 to move. The transmission shaft 55 moves downward under the force transmitted by the transmission gear 56. The transmission shaft drives the transmission block 57 to exert force on the electronic scale 1 6. The experimenter can directly read the torque value through the value on the electronic scale 1 6;

[0023] During the experiment, the experiment can be carried out by replacing the synchronous pulley 1 32 and the synchronous pulley 2 33 of different sizes, and the change of the torque when the synchronous pulley 1 32 and the synchronous pulley 2 33 of different sizes and different ratios are tested;

[0024] During the experiment, the torque meter 42 may be fixedly mounted on the flywheel shaft 31 to perform a torque test, thereby testing the characteristics of the heat engine 2 .

[0025] In one embodiment, the dynamic torque meter assembly comprises a plurality of transmission brackets 51 mounted on the platform 1, a transmission shaft 52 movably mounted on the transmission bracket 51, a transmission gear 53 mounted on the transmission shaft 52, a support frame 54 mounted on the platform 1, a transmission shaft 55 movably mounted on the support frame 54, a transmission gear 56 movably mounted on the transmission shaft 55 and meshingly connected with the transmission gear 53, and a transmission block 57 mounted on the transmission shaft 55 and in contact with the electronic scale 6;

[0026] The transmission shaft 52 drives the transmission gear 53 to rotate. When the transmission gear 53 rotates, it drives the transfer gear 56 meshing with it to rotate. At the same time, the transmission gear exerts a downward force on the transfer gear 56 in the process of driving it to rotate. After receiving the force transmitted by the transmission gear 53, the transfer gear 56 drives the transfer shaft 55 downward. During the downward movement of the transfer shaft 55, it drives the transmission block 57 to move downward. After the transmission block 57 contacts with the electronic scale 6, it squeezes the electronic scale 6 downward due to the force it receives. The value of the force at this time can be directly read on the electronic scale.

[0027] In one embodiment, it also includes a transmission shaft 2 7 movably mounted on the transmission bracket 51, a transmission gear 2 71 mounted on the transmission shaft and meshingly connected with the transfer gear 56, a transmission wheel 72 mounted at one end of the transmission shaft 2 7, and a motor 1 73 mounted on the platform 1 and transmission-connected with the transmission wheel 72;

[0028] Through the arrangement of the transmission shaft 27 and the transmission gear 271, the transmission gear 56 drives the transmission gear 271 to rotate through meshing cooperation in the process of being driven by the force to drive the transmission block 57 to move downward. When the transmission gear 271 rotates, it drives the transmission shaft 27 to rotate, and the rotating shaft 2 drives the transmission wheel 72 to rotate. The transmission wheel 72 drives the motor 1 73 to move. The motor 1 73 generates electricity when it moves. The motor 1 73 can be connected to components such as light bulbs. When the motor moves to generate electricity, the light bulbs are lit.

[0029] In one embodiment, it also includes a motor 2 74 that is transmission-connected to the flywheel 3. When conducting a torque test experiment, the flywheel 3 drives the motor 2 74 to rotate to generate electricity. The motor 2 74 can also be used as a power source. The motor drives the flywheel 3 to rotate in the opposite direction. At this time, the heat engine 2 does not heat and performs a reverse action. The flywheel 3 is driven to rotate by the motor, and the flywheel 3 drives the heat engine 2 to perform a reverse action to form a temperature difference, and the heat engine 2 performs cooling.

[0030] In one embodiment, the heater is an electric heater 8 or an alcohol lamp 81.

[0031] In one embodiment, an electronic scale 82 is also included which is installed on the platform 1. When the alcohol lamp 81 is used as a heating source, it is placed on the electronic scale 82. During the experiment, the amount of alcohol used, the size of the torque generated, and the amount of energy generated can be observed.

[0032] When the utility model is in use, one end of the heat engine 2 is heated by the heater, the heat engine 2 drives the flywheel 3 to rotate, the flywheel 3 drives the flywheel shaft 31 and the motor 2 74 to rotate, the motor 2 74 generates electricity during the rotation, the flywheel shaft 31 drives the synchronous pulley 1 32 to rotate, the synchronous pulley 1 32 drives the synchronous pulley 2 33 to rotate through the synchronous belt, the synchronous pulley 2 33 drives the transmission shaft 1 52 to rotate, the transmission shaft 1 52 drives the transmission gear 1 53 to rotate, the transmission gear 1 53 applies a downward force to the transmission gear 56 through meshing cooperation, and the transmission gear 56 is subjected to the downward force. The downward force drives the transmission shaft 55 and the transmission block 57 to move downward, and the transmission block 57 applies force to the electronic scale 6. When the transmission block 57 applies force to the electronic scale 6, the electronic scale 6 displays the magnitude of the force at this time. At the same time, the transmission gear 56 rotates by cooperating with the transmission gear 1 53. After rotating, the transmission gear 56 drives the transmission gear 2 71 to rotate, and the transmission gear 2 71 drives the transmission shaft 2 7 to rotate, and the transmission shaft drives the transmission wheel 72 to rotate, and the transmission wheel 72 drives the motor 1 73 to rotate. The motor 1 73 rotates again to generate electricity, and the load can be connected after generating electricity.
