Technical Field of the Invention
The present invention relates to a hybrid reducer system providing auto-system protection against overloading and consisting of gear assembly combination different from each other .
The present invention particularly relates to a hybrid reducer system combining planet gear and magnetic gear transmission systems and minimizing friction losses and planet gear system failure during overload.
State of the Art
Systems that change the revolution/torque ratio of the rotational movement by the help of gears are called reducers. Reducers consist of parts such as gears, wheels, shafts and bearings which are positioned in body in terms of structure. The reducers are especially used in electric motors and are connected to the motor output portion for the purpose of obtaining rotational movement at different speeds from drivers such as diesel engine and gasoline engine.
Reducers are utilized by taking factors such as cycle rate, efficiency, size and weight into account. The classification of the reducers is usually carried out according to the number of stages or to the utilized gear type. The most commonly used gear structures are worm reducers, worm screw reducers and planet gear reducers. Planet gears are useful for transmitting high speed ratios via medium-sized gears in a relatively smaller area.
Gearboxes have applications in industry, civil and military vehicles, for instance they are commonly used in helicopters, wind turbines, track type loaders and milling machines. In industrial applications, and gearboxes can operate under constant working conditions or variable working conditions.
As a result of the preliminary search conducted in the state of the art, the patent document numbered "2018/05790" has been examined. In the abstract section of the aforementioned invention, it is disclosed that "wave generator in the harmonic drive is formed by giving the elliptical geometry of the externally rotating FDA motor to the driven part at the sizes to flex the flexible gear so that it can fit to the rigid gear 5 without any play. The elliptical part of the externally rotating FDA motor can flex the flexible gear and the flexible gear, rigid gear is mounted without any play, harmonic drive is mounted on the rigid holder and a harmonic drive reducer with wave-generated externally rotating brushless dc motor is obtained."
As a result of the preliminary search conducted in the state of the art, the patent document numbered "US3301091" has been examined. Said invention discloses a gear system which can solve the existing problems observed in gear systems. Gears and even new or improved type of gear means are in the focal point of said invention. The subject matter product is economical to produce, reliable and has a minimum maintenance and repair cost, as well as has silent and vibration-free operation in the desired configuration and at high gear ratio. The gear system produced provides the necessary power transmission for the desired torque value by easily performing the clutching even when working under heavy load. When the maximum torque is exceeded, the gear system is not subjected to any strain and wearing. Because in this case, it makes a freewheeling movement. In the gear system, the components work
without contact and perform the power transmission. Since all forms of mechanical contact between driving and driven members has been eliminated, the necessity for precision machining and the resultant cost thereof have also been eliminated as well as wearing and noise.
As a result of the preliminary search conducted in the state of the art, the patent document numbered "US3382386" has been examined. Said invention discloses a magnetic gear system using driving and driven gear pairs. These components are housed in a box. It is disclosed that the magnetic resistance varies with the positions of the driving and driven gears in the operation. Thus, the coupling elements generate the coupling forces in relation with this magnetic resistance. The gear ratio is obtained by dividing the magnet number of the magnetic field in the driving gear by the ones in driven gear.
As a result of the preliminary search conducted in the state of the art, the patent document numbered "US20180163337 " has been examined. Said invention discloses a magnetic gear system for washing machine. The washing machine includes a cabinet at its outer portion, a drum into which laundry is placed in inner portion, and a power unit for rotating the drum. The power unit is used to generate the required magnetic field and flux to rotate the drum.
Mechanical gear systems are determined to be noisy and vibrating during operation as well as being expensive for power transmission after the discovery of the magnetic gear systems used in the state of the art. Moreover, the gears are subjected to wear. For that reason, mechanical gears need maintenance and require lubrication frequently. The first magnetic gear systems used, contained the magnetic gear system consisting of driving and driven gears and were externally protected by a box. There was also a certain distance between
the magnetic gears. The invention shows the importance of using magnetic gears in engineering applications. For example, the magnetic gear system used for the washing machine is integrated into a cabinet which is for the external appearance of the washing machine, a drum in which the laundry is placed and the power transmission unit.
As a result, due to the above-mentioned problems and because of the inadequacy of the existing solutions, it became necessary to make an improvement in the technical field.

The electric motor (110), hybrid gearbox (120) and magnetic brake system (130) are connected to each other by an input shaft (102), an output shaft (103), and an elastic coupling (101) .
The input power and rotational motion are generated by the electric motor (110) directly connected to the hybrid gearbox (120) and located on the motor holder (111) .
One side of the hybrid gearbox (120) comprises a ring gear (123), a planet gear (124) and a sun gear (125) as shown in
Figure 2 while other side of it comprises an internal rotor (128), located on an external rotor, and accommodating external rotor magnet pairs (126) and internal rotor magnet pairs (127) . Consequently, a hybrid system is achieved by using both gear and magnetic system together in an external rotor (122) . In the subject matter reducer system (100), in the first stage, planet gear (124) system and in the second stage, concentric magnetic gear system is used. The neodymium external rotor magnet pairs (126) and the internal rotor magnet pairs (127) transmit the power coming from the planet gear (124) system to the output shaft (103) in a contactless manner with a 2mm air gap via the magnetic gear system.
The elastic coupling (101) is used to provide a smoother power transmission over the hybrid gearbox (120) and other components thereof. The input shaft (102) is used to transfer the speed and torque of the electric motor (110) to the hybrid gearbox (120), while the output shaft (103) connects the hybrid gearbox (120) to each other by the determined load. The alignment and levels of the input shaft (102) and the output shaft (103) are controlled by the motor holder (111), the gear holder (121) and the magnetic brake system holder (131) . Furthermore, the motor holder (111), the gearbox holder (121), and the magnetic brake system holder (131) are used in order that they absorb vibrations and maintain at a fixed level.
When the central sun gear (125) is rotated by the electric motor (110) at high speed, the speed is lowered by planet gears (124) and transmitted to the ring gear (123) . The ring gear (123) is rigidly connected from its rear side with the geared external rotor (122) of the magnetic gearwheel, and the entire system is secured by the gear component holders. A contactless magnetic force is generated by the external rotor magnet pairs (126) and the internal rotor magnet pairs (127) placed in the external rotor (122) and the internal rotor
(128), and the rotational movement from the external rotor
(122) to the internal rotor (128) is transmitted by being accelerated. The output shaft (103) is rigidly connected to the internal rotor (128) and transmits the power of the internal rotor (128) to the magnetic brake system (130) shown in Figure 1. The central sun gear (125) and the planet gears (124), a ring gear (123) and the planet gears (124) are in simultaneous contact. The sun gear (125) is located in the center and transmits its torque to the planet gears (124) rotating around the sun gear (125) . Planet gears (124) are able to transmit torque at higher speed ratios than medium sized gears in a relatively small area. The number of teeth
and the angular velocity of each tooth are used in kinematic equations that allow them to perform their duties. These equations determine the distribution of dangerous contact points for accurate analysis of the reliability of a tooth and are used to obtain a random loading history for each gear.
The input shaft (102) is rigidly connected to the sun gear (125) in the center. The electric motor (110) transmits power to the sun gear (125) . It is transmitted from the sun gear (125) to the planet gears (124) and then to the ring gear (123) .
Figure 5 shows concentric magnetic gear system comprised of external rotor (122) . The external rotor (122) is rigidly connected to the ring gear (123) from its rear side, while the internal rotor (128) is rigidly connected to the output shaft (103) of the hybrid gearbox (120) . The internal rotor (128) transmits the power from the external rotor (122) to the output shaft (103) in a contactless manner via the external rotor magnet pairs (126) and the internal rotor magnet pairs (127) .Furthermore, magnet channels (129) which ensure that the external rotor magnet pairs (126) and the internal rotor magnet pairs (127) are placed around the inner surface and the outer surface of the internal rotor (128) and the external rotor ( 122 ) .
Figure 6 shows the array and assembly of neodymium fixed external rotor magnet pairs (126) around the inner surface of external rotor (122) . Figure 7 shows the array and assembly of neodymium fixed internal rotor magnet pairs (127) around the outer surface of internal rotor (128) connected by the output shaft (103) . All the components are concentric, and the system has an air gap. The external rotor magnet pairs (126) and the internal rotor magnet pairs (127) are positioned at equal intervals to the inner surface of the external rotor (122) and
to the outer surface of the internal rotor (128) . When the external rotor (122) is started, the internal rotor (128) is rotated in the same direction as the external rotor (122) by the magnetic field the force in the air gap.
The speed ratio in the first stage of the planet gears (124) is 4:1 and the speed ratio in the second stage of the magnetic internal rotor (128) is 1:2. The output of the input shaft (102) and the output shaft (103) is a distance of 25 mm. The maximum power transmitted by the input shaft (102) is 200 W at 3000 rpm. The combined shock and fatigue factor are 1.5 in torsion and is 2 in bending. The permitted shear stress for the input shaft (102) and output shaft (103) material is 40 kN/mm2. The input shaft (102) and the output shaft (103) used are significant components and are designed such that they can resist bending and shear stresses. Although the input shaft (102) and the output shaft (103) are designed according to the criteria of strength, they are also properly supported on their sides. Thus, they are prevented from buckling or sudden unstable state. Due to the loads exerted, an internal shear force changing from point to point along the axis on the input shaft (102) and the output shaft (103), and moment occurred as result of this shearing force come into being.
The planet gear system (124) provides higher torque load due to load sharing between multiple gear pairs. Although having equal or smaller volume than conventional gear pairs, they produce a bigger transmission rate. All gears are made of steel, whereas the external rotor (122) and the internal rotor (128) are made of aluminum.
