AN ASPHALT MILLING REDUCER THAT ENABLES MODULAR ARRANGEMENT OF PLANETARY GEAR STAGES.

Abstract

This invention relates to an asphalt milling reducer (1) that enables the rotation of at least one milling drum (13) in asphalt milling machines (A). The reducer (1) comprises a first ring gear (9) driven by the first planetary gears (7), a second ring gear (10) driven by the second planetary gears (4), and an output housing (12). The first ring gear (9) and the second ring gear (10) are arranged as separate parts and connected to each other via an intermediate connecting flange (11). Thus, the first ring gear (9) and the second ring gear (10) rotate together at the same speed, transmitting the torque to the output housing (12). The separate ring gear structure allows the planetary gear stages to be sized according to the torque they carry and the reducer (1) to be extended with an additional planetary gear stage.

1 TARIFF PLANET D GEAR STEPS ARE MODULAR A REGULATOR OF ASPHALT MILLING REDUCERS THAT ENABLES ITS REGULATION. Technical Area 5 The invention is used to rotate the milling drum in asphalt milling machines. And in particular, the ring gears belonging to different planetary gear stages are separate parts. It relates to an asphalt milling reducer that is designed as such. Previous Tech 10 Nowadays, in road maintenance and renovation works, the asphalt layer has a specific...

For this purpose, the rotational speed obtained from the motor... The motion is transmitted to the gearbox via a belt and pulley system, and in the gearbox, the motion is reduced by 15 While the speed is reduced, the torque is increased, and the resulting movement is transferred to the drum. is being transferred. Interaction of the milling drum with the asphalt layer during the asphalt milling process. This creates variable operating loads. The gearbox handles these loads. It transmits motion to the scraping drum by meeting the asphalt. In addition, the asphalt... Its decomposition releases large amounts of dust, dirt, and abrasive particles into the working environment. Therefore, the gear sets of the gearbox, along with the input and output bearings, are composed of these components. Sealing elements operate under harsh working conditions. Reducing motor speed and milling in known asphalt milling reducers. Multiple planetary gear stages to increase the torque transmitted to the drum. It is used. Sun gears, planetary gears, planets in each planetary gear stage. The carrier body and the ring gear work together in a related manner. Different 2 Since the torque carried by the stages is different from each other, the gears and The load-bearing components have different sizing requirements. In some known two-stage gearboxes, the first and second planetary stages belong to The circular gear sections are 5 on a wide and solid circular gear. It is arranged. Both stages are within the same monolithic circular gear. Due to its operation, the diameter of the circular gear is larger than that of the final planetary gear, which carries higher torque. It is determined according to the requirements of the level. As a result, more The planetary gears and planetary carrier housing of the low-torque stage are also large. It is sized to fit the diameter of the circle. 10 The lower torque setting is configured for the higher torque setting. Anchor adaptation, parts that are larger than necessary at that stage This leads to its use. The increase in part sizes increases the space occupied by the gearbox. This increases the volume, weight, and amount of material used. Larger gear 15 The production of carrier parts also increases the production cost of the gearbox. Therefore, the stages cannot be sized separately according to different torque levels, this leads to the gearbox becoming structurally and economically unsuitable. It opens. The monolithic circular gear structure allows the planetary gear stages to be independent of each other. It also makes it difficult to change. A different scraping drum revolution. when required, a planetary gear set can have different tooth counts and gear ratios. It is requested that it be replaced with another group that has the same characteristics. However, it is different. In a structure where the stages are located within a common monolithic circular gear, only the relevant 25 Removing and replacing the stage independently becomes difficult. This The situation is that various types of gearboxes with different gear ratios share the same basic output structure. It restricts its creation using this method. 3 In some applications, the total gear ratio obtained with two planetary gear stages, The required scraping drum speed is insufficient. In such a case, additional A planetary gear set is needed. However, the rings belonging to the sets... In gearboxes where the gear sections are in a single, integrated structure, Adding a third level as an independent group becomes difficult. This 5 Therefore, in order to meet the requirement for a higher gear ratio, the gearbox More comprehensive changes than the current system are needed. The use of one-piece circular gears also affects maintenance and repair procedures. Circular gears. When damage occurs to the gear or one of its associated planetary gear stages, 10 Removing or replacing only the parts belonging to the damaged section is always necessary. It is not possible. A wider area is needed to reach the damaged region. disassembly of the gear set or replacement with a common ring gear. This is necessary. These processes increase maintenance time and spare parts costs. This prolongs the downtime of the asphalt milling machine. 15 Another problem encountered in terms of the operating conditions of planetary gear sets is, This occurs in the axial contact area between the sun gear and the gearbox cover. It comes out. In known applications, the sun gear comes out directly with the reducer cover. Sliding contact can occur. The friction resulting from this contact and 20 Using bronze bushings to reduce wear or a dense contact surface the creation of channels, pockets and different surface geometries that facilitate access Solutions such as these are being implemented. These solutions involve lubricating the contact area or the sliding surfaces. It improves working conditions. However, the relationship between metal surfaces... When sliding contact continues, friction occurs between the sun gear and the gearbox cover. Wear and heating occur. These effects lead to mechanical losses in the gearbox. This leads to a reduction in the service life of the relevant parts during long-term operation, and This increases the need for maintenance. 30 4 Dust, dirt, and abrasive particles generated in the asphalt milling process enter the gearbox inlet. It also poses a problem in terms of the sealing elements used in the shaft. The input shaft seal is not adequately protected against the external operating environment. In applications, these particles are found in the contact area between the felt and the shaft. It reaches. The accumulation of particles in this region and their movement during operation 5 Interaction with surfaces causes wear on the seal and shaft surface. As wear progresses, the seal at the inlet area weakens and the gearbox Oil leaks are occurring. The input shaft of the gearbox transmits the motor movement via a belt and pulley system. 10 Therefore, it is also subjected to radial loads. Inside the asphalt milling machine Space constraints may necessitate the use of smaller diameter pulleys. As the pulley diameter decreases, the radial load acting on the input shaft increases, and this load The input shaft is supported by bearings. An increase in radial load causes the input shaft to... this leads to heavier bearing weight, reduced bearing service life, and unexpected 15 This leads to bearing failures. Although these problems occur in different parts of the gearbox, asphalt milling They work together effectively during the process. Solid ring tooth structure. sizing of the stages, changing them according to the cycle rate, additional 20 Adding stages and maintaining the damaged group makes it difficult. With sun gear. Sliding contact between the covers causes mechanical losses and wear. Abrasive particles in the external environment negatively affect the sealing of the inlet seal. High radial loads resulting from belt and pulley drives are affecting it. It puts strain on the input shaft bearing. 25 Therefore, in the known state of the technology, the different planetary gear stages are in a circle. individual sizing of the gears, and if necessary, the relevant gear group enabling modification and the addition of an extra planetary stage; In addition, sun gear bearing, input seal protection and input shaft 30 Asphalt milling work in terms of carrying radial loads on it A suitable asphalt milling reducer is required for these conditions.

Belt and pulley system The present invention relates to a scraping drum (13) of asphalt scraping tools (A). It relates to an asphalt milling reducer (1) for turning. Asphalt milling The gearbox (1) reduces the speed of the rotational movement taken from a motor (B) to 30 8 transmitting the torque required for the scraping operation to the scraping drum (13) Asphalt milling reducer (1) provides road maintenance and renovation operations. It is used in work environments where the asphalt layer is being excavated. In this environment The gearbox (1) is resistant to variable loads, dust, dirt and resulting from the scraping process. It is exposed to abrasive particles. 5 The asphalt milling reducer (1) shown in Figure 1 and Figure 5; from a motor (B) an input shaft (2) to receive the incoming rotational motion, moving from the input shaft (2) The area will serve together with a second sun gear (3), second sun gear (3). The second planetary gears (4) arranged in this way, 10 on the second planetary gears (4) a second sun gear which is supported by a bearing and transmits the rotational motion to a first sun gear (6). Planetary carrier body (5) will operate together with the first sun gear (6) first planetary gears (7), on the first planetary gears (7) a first planetary carrier body (8) on which it is mounted, first planetary gears (7) a first ring gear (9) and a second 15 arranged to work together a second circle arranged to work together with planetary gears (4) It contains gears (10). Here, the stage where the second planetary gears (4) are located is the input. The stage that receives motion from the shaft (2); the stage where the first planetary gears (7) are located It is the stage located on the output side in the torque transmission to the scraping drum (13). The first ring gear (9) and the second ring gear (10) are separate parts 20 They are arranged as such and connected to each other via an intermediate connection flange (11). They are connected and rotate together at the same speed. Asphalt milling reducer (1), It receives from the first ring gear (9) and the second ring gear (10) connected to each other. It transmits the torque to a scraping drum (13) via an output housing (12). In the structure shown in Figure 1, the first ring gear (9) and the second ring gear (10) They are arranged as separate parts. Thus, the first one in question... circular gear (9) and second circular gear (10) and planetary gear working with them The groups can be individually sized according to the torque carried by the respective stages. 9 In the asphalt milling reducer (1), the stage where the second planetary gears (4) are located, lower torque compared to the stage where the first planetary gears (7) are located It carries. In one application of the invention, the diameter of the second circular gear (10) is equal to that of the first. The diameter of the first circular gear (9) is smaller than that of the second circular gear (10). Therefore, the second circular gear (10) second planetary gears (4) and second planetary carrier housing (5), higher torque 5 smaller dimensions than the parts of the first stage that carry It can be formed.
