In the field of floor grinding and polishing, the 1.5KW floor grinding and polishing machine has become the favorite choice of many professional construction personnel and related companies due to its excellent performance and wide application. The gearbox, as one of the core components of the equipment, plays a vital role. This article will deeply analyze the various aspects of the 1.5KW floor grinding and polishing machine gearbox to take you to appreciate its unique charm.

1. The basic structure and working principle of the gearbox
Basic structure
The 1.5KW floor grinding and polishing machine gearbox is mainly composed of key components such as gear sets, bearings, shafts, and housings. The gear set is usually made of high-quality alloy steel materials, which are finely processed and heat treated to ensure its stability and durability under high-intensity operation. The bearings are made of high-precision, low-noise ball bearings or roller bearings, which can effectively support the rotation of the gears and reduce friction losses. The material of the shaft is generally high-quality carbon steel that has been quenched and tempered, with good strength and toughness, and can withstand the transmission of torque. The box is mostly made of high-strength cast iron or aluminum alloy materials, with good rigidity and sealing, providing reliable protection and stable support for internal components.
Working principle
When the 1.5KW motor is started, the power is transmitted to the input shaft of the gearbox through the coupling, and then the gear on the input shaft meshes with other gears inside the gearbox to achieve torque transmission and speed conversion. Through the combination of different gears, the gearbox can output a variety of different speeds to meet the needs of different stages and different materials of floor during floor grinding and polishing. For example, when rough grinding harder wooden floors, a lower speed can be used to obtain greater torque, thereby improving grinding efficiency; while when fine polishing softer composite floors, a higher speed can be used to make the polishing effect more delicate and uniform.

2. Key performance indicators and advantages of the gearbox
Transmission efficiency
The transmission efficiency of the high-quality 1.5KW floor grinding and polishing machine gearbox can reach more than 90%, which means that the power output by the motor can be transmitted to the grinding and polishing disc to the maximum extent, reducing energy loss and improving the overall working efficiency of the equipment. An efficient transmission system can not only save energy consumption, but also achieve faster grinding and polishing speed under the same power input, shorten working time, and thus improve the overall progress and output of the construction project.
Torque output range
This type of gearbox can usually provide a wide torque output range, generally between 10 and 50 Nm, which can be flexibly adjusted according to different floor materials and construction processes. When facing some hard stone floors or severely worn old floors for renovation, the larger torque output can make the grinding and polishing machine easy to deal with, ensuring that the grinding tool can effectively cut into the floor surface, remove old coatings, scratches and flaws, and lay a good foundation for subsequent polishing processes; when dealing with some more delicate floor materials, such as solid wood composite floors or bamboo floors, the smaller torque output can avoid excessive damage to the floor and achieve a more refined grinding effect.
Speed ​​Shift Stability
Stable speed shifting performance is a major advantage of the 1.5KW floor grinding and polishing machine gearbox. In the actual construction process, the condition and construction requirements of the floor may change at any time, requiring operators to be able to quickly and smoothly adjust the speed of the equipment. High-quality gearboxes can achieve smooth switching between different speed gears without obvious setbacks or speed fluctuations, thus ensuring the consistency and uniformity of the grinding and polishing process. For example, when performing multiple grinding processes on the floor, from coarse grinding to fine grinding to polishing, the operator can easily increase the speed step by step through a stable gearbox, so that the grinding effect of each stage can reach the best state, avoiding problems such as uneven grinding marks and poor polishing effect caused by unstable speed.
Noise and vibration control
The 1.5KW floor grinding and polishing machine gearbox focuses on noise and vibration control during the design and manufacturing process. By adopting optimized gear tooth design, high-precision processing technology and effective shock absorption and buffering measures, the noise level of the gearbox during operation can be controlled in a low range, generally not exceeding 75 decibels, providing operators with a relatively comfortable working environment and reducing the impact of noise on the operator’s hearing and physical and mental health. At the same time, good vibration control is also conducive to improving the stability and service life of the equipment, preventing problems such as loose parts, increased wear and uneven grinding and polishing due to excessive vibration.

3. The important role of the gearbox in floor grinding and polishing
Adapting to different floor materials and construction processes
Different types of floors, such as solid wood floors, laminate floors, marble floors, tile floors, etc., have different material characteristics, hardness and surface treatment requirements. The 1.5KW floor grinding and polishing machine gearbox can adjust the speed and torque output according to these differences to make the equipment suitable for grinding and polishing of various floors. For example, for solid wood floors, their texture is relatively soft, but during the grinding process, it is necessary to pay attention to the protection of the wood texture. At this time, medium speed and moderate torque can be used for grinding to avoid damaging the wood surface; while for marble floors, their hardness is high and the surface finish requirements are high. In the early stage of grinding, it is necessary to use a lower speed and a larger torque for rough grinding, gradually remove the unevenness and scratches on the ground, and then gradually increase the speed and cooperate with finer grinding tools for fine grinding and polishing, and finally achieve a mirror effect. This adaptability of the gearbox enables the 1.5KW floor grinding and polishing machine to meet the diverse needs of different customers in different scenarios, and become an essential equipment in floor renovation, decoration projects and daily maintenance.
Improve the quality and efficiency of grinding and polishing
During the floor grinding and polishing process, the performance of the gearbox directly affects the quality and efficiency of grinding and polishing. An efficient gearbox can ensure the stable transmission of power, so that the grinding and polishing disc contacts the floor at a suitable speed and pressure, thereby achieving a more uniform and thorough grinding effect. For example, when renovating a large area of ​​commercial building floors, using a 1.5KW floor grinding and polishing machine equipped with a high-quality gearbox can quickly remove the old wear layer, level the floor, and quickly achieve the required gloss and smoothness in the subsequent polishing process, greatly improving construction efficiency and shortening project duration. At the same time, the stable speed change function can also avoid problems such as uneven grinding marks and insufficient polishing caused by unstable equipment speed, ensuring that the appearance and performance of the floor after grinding and polishing can meet high standards, improving the quality and customer satisfaction of the entire construction project.
