FULLY AUTOMATIC CIRCULAR SAW GEARBOX ASSEMBLY WITH SINGLE-STAGE GLOBOID GEAR MECHANISM

Abstract

According to this invention, the gearbox of a fully automatic circular saw machine is configured to include a globoid gear (3.1) and a globoid screw (3.2) that engages with this globoid gear (3.1). The globoid screw (3.2) and globoid gear (3.1) are positioned to engage directly within the same housing, forming a single-stage reduction structure without an intermediate shaft or gear. Thanks to this structure: backlash sources occurring in multi-stage gear systems are eliminated, shocks generated during cutting are dampened thanks to the globoid gear engagement, and power transmission is made more linear and stable. The globoid screw (3.2) can be connected directly or as a single piece to the output shaft of the motor (2); the globoid gear (3.1) can be connected directly to the output shaft carrying the circular saw blade. The invention is particularly suitable for use in cutting hard metal materials.

Description

1 TARIFF FULLY AUTOMATIC CIRCLE WITH SINGLE-STAGE GLOBOID GEAR MECHANISM CHAINSAW GEARBOX ASSEMBLY Relevant Technical Field: 5 The invention enables fully automated cutting requiring high precision in circular saw machines. In their machines, metal profiles, rods and similar workpieces are processed stably, without vibration, and made in the circular saw gearbox assembly for the purpose of cutting with a smooth surface finish. It relates to development. Previous Technique: In conventional circular saw machines, motor output power is usually distributed through multi-stage gear systems. This information is transmitted to the saw blade via this method. In such multi-stage gear systems: - The high number of gears, - The use of intermediate shafts and intermediate gears, 15 - Accumulation of gear engagement gaps, Backlash occurs due to vibration, especially when cutting hard materials. This leads to bouncing, surface distortion, and reduced cutting accuracy. The machine is particularly useful when cutting stainless steels and relatively hard alloy steels. Mechanical vibrations occur when the blade needs to rotate at a low speed. Traditional 20 In these machines, this problem is caused by a brake placed at the rear of the output shaft pushing the gears backward. and attempts have been made to solve this by compensating for the gear gaps. However, a softer approach... While this method is partially useful during the cutting of materials, it is not particularly useful for cutting hard materials. Unfortunately, this is not a complete solution, leading to a dramatic decrease in cutting tool life and This makes it impractical to cut these types of materials on these machines. 25 In the current state of the art, mechanical brakes and friction brakes are used to reduce these problems. It appears that complex adjustment mechanisms or elements are used. However, these solutions, This complicates the system, increases the need for maintenance, and does not always provide sufficient vibration. It is unable to provide damping. 30 Digitally controlled circular saw, model number CN104500710A, showing the state of the art.

Circular saw cutting machine, number US6330848, showing the known state of the art. The patent document discusses gear-induced "chatter" vibration with flywheel / inertia and condition sets. The suppression approach is being discussed. Purposes of the Invention: The aim of this invention is to structurally redesign the gearbox assembly used in circular saw machines. By simplifying, gear backlash and vibration problems are addressed by adding an extra brake or friction mechanism. It is about offering a solution that reduces the need for it. This purpose involves a single-stage globoid screw – globoid gear arrangement in the transmission group. This was achieved through its use. Thanks to the high-precision power transmission from the gearbox, the material is stable. It is intended to be cut at the line. Another aim of the invention is to obtain a vibration-free, continuous and globoid gear mechanism. Linear power transmission, smoother surface quality in cutting operations, lower wear rate. and ensures a much longer tool life.

(1) includes a motor (2), a gearbox assembly (3) and a fixed clamp (4). The rotational movement produced by the motor (2) is transmitted to the circular saw via the gearbox (3) It is transmitted to the blade. The gearbox assembly (3) provides a globoid gear that provides a single-stage reduction. It includes (3.1) and globoid screw (3.2). As shown in Figure 2, the globoid screw (3.2) and globoid thread (3.1) share the same housing body. It is positioned to grip directly inside. Globoid gear (3.1), circular saw 15 It is positioned so that it is directly connected to the output shaft carrying the blade. This structure, Reducing mechanical clearances by eliminating the need for intermediate shafts and gears in the system. It provides. The globoid screw (3.2) will be directly or in one piece to the output shaft of the motor (2). They are connected in this way. Thanks to the high contact surface area provided by the globoid gear geometry, Vibrations and impacts generated during cutting are dampened, thus making it especially effective on hard surfaces. During material cutting, bouncing and surface distortions are significantly reduced. The cabinet group (1), which is the carrier of the entire mechanical structure, the gearbox group (3), the motor connection housing all the components and mechanisms including the circular saw blade. It provides the structural integrity necessary for the system to function. 25 The globoid screw-gear system (3.2, 3.1) located within the gearbox assembly (3) is a conventional multi-gear system. Unlike multi-stage gearboxes, it has an extremely simple yet highly efficient drive structure. This mechanism consists of only one globoid screw (3.2) and one globoid gear (3.1) Because it consists of elements and has a globoid geometry with a high contact surface area, it is particularly suitable for... A structure that reduces vibration and rebound during the cutting of hard materials. 30 is being created. The motor (2) provides the necessary rotational energy to the system, enabling the movement directly through the globoid gear. It ensures that the high speed produced by the motor (2) is transferred to the system (3.1, 3.2). 4 The rotational movement is determined by the geometric structure of the globoid gear mechanism (3.1, 3.2). The reduction ratio is applied accordingly, resulting in high torque and low speed at the output end. This combination provides the ideal cutting performance for the circular saw blade. This is achieved by transmitting this controlled and stable rotational motion to the saw blade. This makes it possible to perform the cutting operation in a stable manner. 5 The workpiece to be cut is fixed on the fixed vise group (4) in the correct position. The rigid structure of the vise group (4) is held in place to prevent vibrations that may occur during cutting. By absorbing the material, it ensures that the part's position remains fixed at all times. This situation provides both... It is a factor that directly increases both cutting accuracy and surface quality. 10 The circular saw blade, given a rotational motion, receives high precision from the gearbox assembly (3). Thanks to power transmission, it cuts the material in a stable line when it comes into contact with the workpiece. Vibration-free, continuous and linear power obtained from the globoid gear mechanism (3.1, 3.2) transfer, smoother surface quality in the cutting process, lower wear rate and much more This ensures a long tool life. These structural advantages are particularly beneficial for metals with high hardness. 15 It provides a significant performance increase in cutting parts.
