Abstract
Description
Technical Field
[0001] This invention relates to the field of floor grinding equipment technology, and in particular to a design method for gear transmission systems of floor grinding machines. It is a parametric design method for gear transmission systems applicable to multi-disc square floor grinding machines and multi-disc multi-motor circular floor grinding machines. Background Technology
[0002] Floor grinding machines are key equipment in building decoration and floor treatment, widely used for grinding, polishing, and leveling hard surfaces such as concrete and stone. Based on their structural form, floor grinding machines are mainly divided into two categories: circular floor grinding machines and square floor grinding machines. Circular floor grinding machines utilize the combined rotation and revolution of the grinding discs to create overlapping grinding tracks, achieving high construction efficiency and good surface uniformity in large-area applications, making them the most widely used type of floor treatment equipment. Square floor grinding machines, with their square body structure and arrayed grinding discs, ensure more uniform coverage of the working area, reducing uncovered areas between adjacent grinding tracks, thereby improving the coverage and construction efficiency of the floor grinding process.
[0003] In the aforementioned equipment, multi-grinding disc structures typically require a gear transmission system to achieve power distribution and coordinated motion. This transmission system generally includes components such as input gears, output gears, and transition gears. The number of gear teeth, transmission ratio, and spatial position of the gears not only affect the grinding disc rotation speed and motion trajectory but also directly relate to the equipment's transmission efficiency, load distribution, and structural compactness.
[0004] However, in existing technologies, the design of gear transmission systems for floor grinding machines largely relies on experience or simplified models, lacking a systematic method for determining parameters. Key parameters such as grinding disc diameter, grinding width, center distance, and grinding disc layout are usually obtained through empirical estimation, which can easily lead to insufficient or excessive overlap of the grinding disc coverage area, affecting grinding efficiency and energy consumption. Furthermore, in multi-grind disc linkage structures, the selection of gear teeth, transmission ratio configuration, and the position of transition gears must meet spatial constraints and power transmission requirements. For circular multi-grind disc structures, the coordination and matching between the upper and lower gear transmission relationships and the number of motor inputs must also be considered, further increasing the overall design complexity.
[0005] Therefore, it is necessary to propose a design method for the gear transmission system of a floor grinding machine that can systematically determine the grinding disc layout parameters, the number of gear teeth, the transmission ratio configuration, and the position of the transition gear, so as to synergistically optimize the grinding disc motion trajectory, transmission chain stability, and structural compactness, thereby improving the grinding uniformity, transmission efficiency, and engineering application reliability of the equipment. Summary of the Invention
[0006] This invention proposes a design method for the gear transmission system of a floor grinding machine, aiming to solve the problem of the lack of a systematic design method for the gear transmission system of floor grinding machines in the prior art. It is applicable to both round and square floor grinding machines. By systematically calculating the number of motors and gear transmission parameters, it can achieve a comprehensive match between the grinding disc layout and the gear transmission system, thereby improving grinding uniformity, transmission stability and equipment structure compactness.
[0007] The present invention adopts the following technical solution.
[0008] The design method for the gear transmission system of a floor grinding machine includes the following steps;
[0009] Step 1: Determine the diameter, grinding width, center distance, and cross length of the grinding machine's grinding disc, and calculate the grinding parameters of the grinding machine through geometric relationships;
[0010] Step 2: Based on the number of grinding discs and their center distance, determine the arrangement of the input and output gears of the gear transmission system required for the grinding discs;
[0011] Step 3: Design the lower gear ratio, input gear teeth number, and output gear teeth number of the gear transmission system to match the power transmission requirements;
[0012] Step 4: Design the gear transmission system according to the structure type of the grinding machine.
[0013] In step one, the grinding disc diameter, grinding width, cross length, and center distance are analyzed to determine some of these parameters, and the remaining parameters are calculated.
[0014] When the grinding machine is a square floor grinding machine, the relationship between the diameter of the grinding disc, the grinding width, the cross length, and the center distance is as follows:
[0015] ;
[0016] In the formula, The diameter of the grinding disc. For grinding width, The cross length, Center distance;
[0017] If the grinding width and cross length are known in the embodiment of the square floor grinding machine, and are , .thereby , .
[0018] When the grinding machine is a circular floor grinder, the relationship between the diameter of the grinding disc, the grinding width, the cross length, and the center distance is as follows: .
[0019] If in a circular floor grinder, the cross length is 0, and the diameter and width of the grinding disc are known, and , .thereby .
[0020] In step two, first determine the number of grinding discs, and use the default input gear position as the origin. Then, determine the position of the output gear based on the number of grinding discs and the center distance.
[0021] In step two, first determine the number of grinding discs, and use the input gear position as the origin by default. Then determine the position of the output gear based on the number of grinding discs and the center distance.
[0022] When the grinder is a square floor grinder, take the input gear position as point (0,0) of the coordinate center, and let the output gear position be... , , , ;in

[0029] In the formula, , This refers to the number of grinding discs on a circular floor grinder.
[0030] When the number of grinding discs is three The value is set to 3, and the position of the output gear is... , , .
[0031] In step three, the lower gear ratio, the number of teeth on the input gear, and the number of teeth on the output gear of the gear transmission system are analyzed to determine two of these parameters, and the remaining parameter is calculated. Specifically:
[0032] The formulas for determining and calculating the lower gear ratio, input gear teeth number, and output gear teeth number of the gear transmission system of a floor grinder are as follows: ;
[0033] In the formula, To input the number of teeth on the gear, The number of teeth on the output gear. This represents the tooth ratio of the lower layer.
[0034] If the number of teeth and transmission ratio of the input gear in the embodiment of the square floor grinder are known, and , ,but Since the number of teeth does not have a decimal, the result needs to be rounded.
[0035] If the number of teeth and transmission ratio of the input gear in the embodiment of the circular floor grinder are known, and , ,but .
[0036] When the grinding machine is a square floor grinding machine with a square structure, in step four, the number of teeth of the transition gear is calculated based on the principle of minimum number of teeth of the transition gear, and the position of the transition gear is determined;
[0037] When the grinding machine is a circular floor grinding machine with a circular structure, in step four, after determining the number of motor inputs of the grinding machine, the number of teeth of the transition gear, the upper gear ratio, the number of teeth of the upper pinion, and the number of teeth of the upper gear are analyzed to determine several parameters and calculate the remaining parameters. At the same time, the position of the transition gear is determined. That is, the upper and lower gear parameters of the gear transmission system are determined through the transmission relationship, including the upper gear ratio, the number of teeth of the transition gear, the number of teeth of the upper pinion, the number of teeth of the upper gear, and the position information of the transition gear.
[0038] As attached Figure 2 The diagram shown is a schematic representation of an embodiment of a square floor grinder. The figures depict the pitch circle positions of each gear, using the pitch circle positions to represent the actual gear positions. Circle 1 represents the pitch circle of the input gear, circles 2 and 3 represent the pitch circles of the intermediate gears, and circle 4 represents the pitch circle of the output gear.
[0039] In step four, for the square floor grinder, the motor receives power through the input gear (gear 1), which is then transmitted through the intermediate gears (gears 2 and 3) and finally output by the output gear (gear 4). Based on the principle of minimum number of teeth for the intermediate gears, the number of teeth and their position information are optimized. Specifically, a first intermediate gear and a second intermediate gear are set in the square floor grinder, and both have the same number of teeth. The optimization formula for the principle of minimum number of teeth for the intermediate gears is:
[0040]
[0041] In the formula, Let be the coordinate position of transition gear 1. The input gear's pitch circle radius. The pitch circle radius of the first transition gear. The pitch circle radius of the second transition gear. The pitch circle radius of the output gear;
[0042] If all gears have a module of 2.6 and a helix angle of , Then we can obtain .
[0043] The position of the transition gear is determined using the following formula:
[0044] Position of the first transition gear:

The diagram depicts the pitch circle positions of each gear, representing their actual positions in place of their actual positions. Specifically, circle 1 represents the pitch circle of the input gear, circle 2 represents the pitch circle of the intermediate gear, circle 3 represents the pitch circle of the output gear, circle 4 represents the pitch circle of the upper pinion, and circle 5 represents the pitch circle of the upper gear.
[0053] In step four, for a circular floor grinder with a single motor and three grinding discs, the motor inputs power through the input gear (gear 1), the power is transmitted through the transition gear (gear 2), and then through the upper gear mechanism (gear 4 and gear 5), and finally outputs power through the output gear (gear 3); the number of teeth of the transition gear, the upper gear ratio, the number of teeth of the upper pinion, and the number of teeth of the upper gear have the following relationship.

In Example 1 of the circular single-motor 3-disc floor grinder, the upper small gear... Ratio of the number of teeth to the upper layer It is known that, and , The number of teeth on the transition gear can be obtained. The number of teeth on the upper gear .
[0057] The formula for calculating the position information of the transition gear through the transfer relationship is as follows:
[0058]
[0059] In the formula, The coordinates of the transition wheel for the circular floor grinding machine.
[0060] The coordinates of the transition gear in Example 1 of the circular floor grinder can be obtained using the above formula. , , .
[0061] Figure 4 The diagram shows the final effect of the circular dual-motor three-disc floor grinder, as illustrated in Example 2. The diagram depicts the pitch circle positions of each gear, representing their actual positions in place of their respective pitch circles. Specifically, circle 1 represents the pitch circle of the input gear 1 that controls its rotation, circle 2 represents the pitch circle of the intermediate gear, circle 3 represents the pitch circle of the output gear, circle 4 represents the pitch circle of the upper pinion (the input gear that controls its revolution), and circle 5 represents the pitch circle of the upper large gear.
[0062] In step four, for a circular dual-motor three-disc floor grinder, assume that its two motors are powered by the input gear (gear 1) used to control rotation and the upper small gear (gear 4) used to control revolution, respectively. After the power is transmitted through the gears, it is finally output by the output gear (gear 3). The number of teeth of the transition gear, the ratio of the number of teeth of the upper gear, the number of teeth of the upper small gear, and the number of teeth of the upper large gear have the following relationship.
[0063]
[0064]
[0065] If the lower gear uses a module helix angle Helical gears. The upper gear uses a module of... , Helical gears. And the upper gear has a higher tooth count than... And the number of teeth of the upper large gear It is known that, among which , That is, the number of teeth of the upper pinion. And obtain the number of teeth of the transition gear. .
[0066] The formula for calculating the position information of the transition gear through the transfer relationship is as follows:
[0067] .
[0068] Using the above formula, the position of the transition wheel in the circular dual-motor 3-disc floor grinder of Example 2 is obtained as follows: , , .
[0069] The advantage of this invention lies in providing a standardized and calculable design process for the gear transmission system of floor grinders, applicable to square and round floor grinders of different specifications, effectively improving equipment performance and reliability. This method establishes a geometric relationship model between the grinding disc diameter, grinding width, cross length, and center distance, and performs collaborative calculations based on the transmission ratio, tooth configuration, and spatial layout of the gear transmission system, achieving integrated design of the grinding disc arrangement and gear transmission system. For round floor grinders, the number of motor inputs can be determined according to structural requirements, further completing the matching design of gear transmission parameters. This technology solves key technical problems such as parameter matching and optimized arrangement of transition gears in multi-disc floor grinder gear transmission systems, significantly improving the design efficiency and reliability of the transmission system.
