Abstract

The invention relates to a vibration system (200) used in concrete finishers, which are utilized in areas where concrete is laid. Specifically, the invention concerns a vibration system (200) that includes a bearing bushing element (220) used in the bearing of the motor shaft (230). This system is designed to prevent unwanted axial movement of the rotational motion transmitted from the hydromotor (210) to the motor shaft (230), which is between the hydromotor (210) and the vibration shaft (240), as the motion is transferred to the vibration shaft (240).

Description

[0001] VIBRATION SYSTEM USED IN CONCRETE FINISHERS

[0002] TECHNICAL FIELD

[0003] The invention relates to a vibration system used in concrete finishers, which are utilized in areas where concrete is laid.

[0004] Specifically, the invention concerns a vibration system that includes a bearing bushing element used in the bearing of the motor shaft. This system is designed to prevent unwanted axial movement of the rotational motion transmitted from the hydromotor to the motor shaft, which is between the hydromotor and the vibration shaft, as the motion is transferred to the vibration shaft.

[0005] PRIOR ART

[0006] Concrete finishers are used on roads, tunnels, and other areas requiring concrete laying worldwide. Research and development efforts on concrete finishers contribute to the economy by reducing concrete waste and improving work quality.

[0007] In current technology, the low quality of concrete laid by concrete finishers negatively impacts the quality of the concrete and increases material consumption.

[0008] The inadequacies of the vibration systems in existing concrete finishers and the high risk of malfunction also degrade the concrete quality.

[0009] In the current technology, the gear group used in vibration systems of concrete finishers is directly positioned on the vibration shaft. As a result, deformation occurs in the gear group due to vibrations, leading to malfunctions.

[0010] Consequently, technical improvements were deemed essential to address this issue. OBJECT OF THE INVENTION

[0011] The primary objective of the invention is to enhance the quality of concrete laying applications, thereby improving structural quality and enabling material savings.

[0012] Another objective is to improve the quality of concrete in concrete finishers and minimize the risk of malfunctions in the vibration systems of these finishers.

[0013] A further objective is to reduce the risk of malfunctions by limiting unwanted directional movement of the vibration shaft using a bearing system positioned in the vibration system, thereby enhancing concrete quality by effectively transmitting the generated vibrations.

[0014] The primary objective of the invention is to enhance the quality of concrete laying applications, thereby improving structural quality and enabling material savings.

[0028] DETAILED DESCRIPTION OF THE INVENTION

[0029] Figure 1 shows the concrete finisher mold (100) and the vibration system (200) positioned on the concrete finisher mold (100), used to compact the concrete by generating vibrations. Figure 2 shows an exploded view of the vibration system (200). Figures 3 and 4 illustrate the hydromotor (210), bearing bushing element (220), and motor shaft (230). The vibration system (200) uses a hydromotor (210) to generate vibrations. Additionally, in the invention, one end of the motor shaft (230) is connected to this hydromotor (210), while the other end is connected to the motor shaft connection area (241) on the vibration shaft (240) as shown in Figure 5. Between the hydromotor (210) and the vibration shaft (240), a bearing bush element (220) is located, which is used for the bearing of the motor shaft (230). The bearing bushing element (220) is employed to prevent unwanted axial movement when the rotational motion transmitted by the hydromotor (210) to the motor shaft (230) is transferred to the vibration shaft (240). By ensuring the proper transfer of movement from the hydromotor (210) to the vibration shaft (240), both the vibration shaft (240) and the hydromotor (210) are protected, and concrete efficiency is increased. Without the bearing bushing element (220), the motor shaft (230) would not be referenced, allowing it to move along the x and y axes. In this case, unwanted movement in the x and y directions would occur in the motor shaft connection area (241) on the vibration shaft (240) alongside the rotational movement. These movements cause impacts, leading to damage to the hydromotor (210) and the vibration shaft (240). By using the bearing bushing element (220) in the invention, only rotational movement is transmitted to the motor shaft connection area (241) on the vibration shaft (240), thereby protecting the vibration system (200) and improving concrete quality. The invention relates to a vibration system (200) used in concrete finishers, which are employed in areas where concrete is laid. The vibration system (200) includes a bearing bushing element (220) positioned between the hydromotor (210) and the vibration shaft (240). This element is used in the bearing of the motor shaft (230) to prevent unwanted axial movement when the rotational motion transmitted by the hydromotor (210) to the motor shaft (230) is transferred to the vibration shaft (240).
