Description

Technical field

[0001] The invention relates to engines. Technical background

[0002] A method for adding the delivery power of motors is known, which solves the problem of summing the delivery power of several motors on a shaft (Gawrilenko, BA: The Hydraulic Drive, page 21). A disadvantage of this method is the necessity of using a dynamic fluid transmission.

[0003] DE 10 2014 003 958 A1 discloses a system for the reciprocal connection of two shafts with a constant mutual tooth engagement. DE 10 2012 001 232 A1 discloses a self-centering wheel with a wheel rim and a hub, which are connected to each other by means of an endless chain. Support points for the chain are sprockets whose axes of rotation are mounted on the wheel rim and on the hub. One or more springs are integrated into sections of the chain. An objective of the invention is the summation of the delivery capacities of motors using a mechanical transmission. Disclosure of the invention

[0004] The stated objective is achieved by a method of adding the delivery rates of motors according to claim 1 or a device for adding the delivery rates of motors according to claim 2.

[0005] In an inventive method for adding the delivery powers of motors and transferring these delivery powers to a resultant shaft, a universal self-centering system is used for each motor. This system has an outer and a central web, which are separated by a bearing and on which sprockets are rotatably mounted and connected by a closed chain. A geometric point on the outer web, which coincides with the center of a circle passing through the axes of rotation of the sprockets on the outer web, does not coincide with a geometric center of the central web, which geometric center of the central web coincides with the center of a circle passing through the axes of rotation of the sprockets on the central web. Transfer gears are mounted on the sprockets of one of the bearings, which transmit a torque to a gear on an output shaft.The output shafts of each universal self-centered system are connected to a summing shaft on which the summed delivery power of all motors is concentrated.

On Fig. 2 the device is presented from the perspective of a resulting wave. On Fig. Figure 3 shows a cross-section of the device. On Fig. Figure 4 shows a cross-section of the device without gears. On Fig. 5 the device is presented in an isometric manner from the perspective of the motors. On Fig. Figure 6 shows a universal self-centering system of the device.

On Fig. Figure 8 shows the addition of the vectors of forces acting on the sprockets of the universal self-centered system. On Fig. Figure 9 represents vectors of forces acting in the rotating universal self-centered system. Embodiments of the invention

[0006] In a device for implementing the method, two universal self-centering systems are used, each consisting of a central web 1 and an outer web 2, which are shared by a bearing 15. On the central web 1, sprockets 3, 4, 5 are rotatably mounted about axes 19. On the outer web 2, sprockets 6, 7, 8 are rotatably mounted about axes 16. The axes of sprockets 7 and 8 are mounted on a spring 17. The sprockets 3, 4, 5, 6, 7, 8 are sequentially connected by a closed chain 16. Transfer gears 9, 10, 11 are mounted on the sprockets 3, 4, 5 and mesh with a gear 12 of an output shaft 13. Motors 20 and 21 are connected to the central webs 1 of the universal self-centering systems. The output shafts 13 are connected to a summing shaft 25 by means of gears 22, 23 and 24.

[0007] The center of a circle passing through axes 18 does not coincide with the center of a circle passing through axes 19. These circle centers are the geometric centers of the universal self-centered systems. Forces a, b, c act on the sprockets 3, 4, 5, 6, 7, 8, as shown on Fig. 9. The sum of these vectors is given by Fig.Figure 8 illustrates this. The resulting force of 107.10 N is tangential to the sprockets 3, 4, and 5, causing them to rotate and the chain 16 to move along its perimeter. The transfer gears 9, 10, and 11 rotate along with the sprockets 3, 4, and 5. Torque is transmitted to the output shaft 13 via gear 12. The output shafts 13 of each of the universal self-centering systems do not affect each other. Any additional torque applied to an output shaft 13 only changes the speed of the chain 16 and does not affect the rotational speed of the guides 1 and 2. The combined output of both motors 20 and 21 is generated on the sum shaft 25.

[0008] Universal self-centering systems can use discs or rollers connected to each other by cables or belts. The method of adding the delivery capacities of motors is applicable to any number of motors.
