• What factors should be considered when choosing a hard-toothed gear reducer or a soft-toothed gear reducer

  When choosing a hard-toothed gear reducer or a soft-toothed gear reducer, the load situation, working environment, speed requirements, noise limits, installation space, maintenance costs and other factors should be comprehensively considered. The specific content is as follows: Load size: If the equipment needs to withstand heavy load, such as mine crushers, metallurgical rolling mills, etc., a hard-toothed gear reducer should be selected, which has strong load-bearing capacity and can withstand large torque and impact forces. If it is a light-load equipment, such as packaging machines, textile machinery, etc., the soft-toothed gear reducer can meet the requirements. Although its load-bearing capacity is relatively low, it can also ensure the normal operation of the equipment. Working environment: The hard-toothed gear reducer can work in harsh environments such as high temperature, high humidity, and dust, and can adapt to complex working conditions in mining, cement and other industries. Soft toothed gear reducers are suitable for use in relatively mild environments and have poor adaptability to extreme working conditions. They are generally used in indoor light industrial equipment. Speed requirements: Hard-toothed reducer is suitable for high-speed occasions and has high transmission efficiency

• How to judge the quality of hard-toothed gear reducers and soft-toothed gear reducers

  To determine the quality of hard-toothed gear reducers and soft-toothed gear reducers, you can start from the following aspects: Appearance inspection: The shell of the high-quality reducer is finely crafted, has a flat and smooth surface, and has no casting defects, scratches or rust. At the same time, the nameplate information of regular products is clear and marked with models, specifications, manufacturers, etc. If the nameplate is vague or defective, you need to be wary of product quality issues. Running sound: The quality can be judged by listening to the sound when the reducer is running. The high-quality reducer runs smoothly and has uniform sound without abnormal noise, impact or vibration. You can use a screwdriver to contact the reducer housing on one end and close to the ear to listen to the internal sound more clearly. If there are abnormalities such as harsh friction, it means that there may be quality problems. Temperature change: After the reducer with good quality has been running for a period of time, the temperature rises within a reasonable range and there will be no overheating. If the shell is very hot, it indicates poor heat dissipation or internal faults, which may be due to poor quality.

• How to determine whether the different axial degrees of the axis line of the ZL65 soft tooth surface reducer meet the requirements

  To determine whether the different axial degrees of the axis line of the ZL65 soft tooth surface reducer meet the requirements, you can use the following methods: Use measurement tools to detect: Dial meter measurement method: Fix the dial meter to the housing or other stable parts of the reducer, so that the measuring head of the dial meter is against the surface of the shaft end to be measured, and slowly rotate the axis. The swing range of the dial meter pointer is the radial jumping amount of the axis line, and different axial degrees can be judged based on this. If the amount of jump exceeds the allowable range, it does not meet the requirements. Generally, soft tooth surface reducers allow a certain degree of shaft system deviation, if allowed The shaft system deviation within 0.15mm does not affect the transmission accuracy. Micrometer measurement method: For the journal part, you can use a micrometer to measure the diameters of different positions. By comparing the measurement values, you can judge the roundness and cylindricality of the journal, which indirectly reflects the situation of the axis line. If there is obvious non-circumference or cylindrical error in the journal, it may mean that there are different axes problems in the axis center. Observe the running status and judge:

• What is the difference between applying grease to different models of cylindrical gear reducer

  Different models of cylindrical gear reducer grease apply different grease models, application amount and application method. The specific details are as follows: Grease model selection: Select according to speed: High-speed cylindrical gear reducers should use low viscosity and good fluidity grease, such as fully synthesized high-temperature high-speed reducer grease, which will help reduce operating resistance and prevent excessive heat from being generated due to friction. Low-speed reducers can use high viscosity greases, such as molybdenum disulfide lithium grease, which has good wear resistance and can provide good lubrication protection for gears at low speeds. Selection according to load: For light or medium load cylindrical gear reducers, ordinary lithium-based grease or molybdenum disulfide lithium-based grease can usually meet the requirements. However, heavy-load reducers require the use of fully synthetic molybdenum disulfide reducer grease, etc. This type of grease has excellent extreme pressure and anti-wear properties, and can effectively protect the gear surface under high loads and reduce wear. According to the working temperature

• How to check the lubricating oil condition of K67-20-4KW-4P hard tooth surface reducer

  To check the lubricating oil condition of the K67-20-4KW-4P hard-tooth surface reducer, you can follow the following steps: 1. Cut off the power supply and cool: Cut off the power supply of the reducer before inspection to prevent the danger of electric shock, wait for the reducer to cool down, avoid high-temperature scalding, and at the same time, it can also stabilize the lubricating oil, which is convenient for accurate inspection. 2. Check the oil level: Find the oil level screw plug of the reducer, which is usually located on the side of the reducer housing. Unscrew the oil level screw plug and observe the oil level. If the oil level is near the oil level screw plug hole or slightly lower than the orifice, it means that the oil volume is normal; if it is significantly lower than the orifice, the oil volume is insufficient and lubricating oil needs to be added. For reducers with oil level windows, you can directly observe the windows. The oil level should be stable in the windows during operation. The range of 1/2 to 2/3 should also be within a reasonable range when shutting down. If it is below the lower warning line, oil must be replenished. 3. Check the quality of the oil: Open the drain screw plug and take a small amount of oil sample into a clean container. Observe the color and transparency of the oil,

• What are the effects of gear damage on the performance of GSAT67-Y0.75KW-121.33-M1 reducer

  Gear damage will have many adverse effects on the performance of GSAT67-Y0.75KW-121.33 reducer, as follows: Decreased transmission efficiency: Gear damage will make the meshing between gears no longer accurate, energy loss during transmission increases, resulting in a decrease in the output torque of the reducer or an increase in input power. The reducer needs to consume more energy to complete the same work, resulting in waste of energy. Unstable speed: deformation, wear, etc. of tooth shape will cause uneven meshing clearance of the gear pair, causing 'impact' or 'stuttering' during the transmission process, affecting the speed uniformity of the reducer output shaft, and making it difficult to maintain a stable operating speed. Transmission ratio fluctuation: Standard tooth shape is the basis for ensuring a constant transmission ratio. After the gear is damaged, the actual meshing point deviates from the theoretical position, which will lead to instantaneous transmission ratio fluctuations. For some equipment that requires accurate transmission ratios, it may cause a decrease in operating accuracy. Vibration and noise aggravated: tooth surface wear, local peeling

• How to detect damage to the gear of the SAT87-Y5.5KW-96 reducer

  To detect the damage to the gear of the SAT87-Y5.5KW-96 reducer, you can use the following methods: Appearance inspection: Direct observation: Use the naked eye or a magnifying glass to carefully check the surface of the gear to check for obvious cracks, fractures, peeling, and wear marks, and pay attention to color changes, such as whether there are color changes caused by oxidation, rust or overheating. Coating method: Apply a thin color coating to the surface of the gear, and then let the gear run in normal working conditions for a period of time. Remove the gears and check the wear of the color coating. Where the color coating disappears is usually the area with more severe wear. Measurement inspection: Dimension and geometric shape measurement: Use calipers, micrometers or gear measuring instruments to measure the gear's teeth thickness, tooth pitch, tooth surface roughness and radial jumping, etc., and compare it with the new product standard value to analyze whether there is wear or deformation. Tooth shape inspection: Use a projector to enlarge the tooth shape, observe and compare the changes in the tooth profile,
