- How to ensure the quality stability of heat treatment process in the fourth-level hard tooth surface DFY225 gear reducerTo ensure the mass stability of the heat treatment process in the DFY225 gear reducer, you can start from the following aspects: Control the material quality: Choose steel with narrow hardenable belts, because the narrower the hardenable belts, the more stable the deformation. At the same time, controlling the A1/N content ratio in the range of 1-2.5 can narrow the hardenable belt and reduce deformation. Pay attention to the frame segregation and strip-like structure of the material to avoid affecting the uneven deformation and uneven carburization of the gear spline holes. Optimized preparatory heat treatment: For gear forgings of DFY225 gear reducer, if the normalized hardness is too high, the crystal is mixed, and a large amount of Sorthine or Wei's tissue is present, the inner hole will be deformed and enlarged. Therefore, temperature-controlled normalized fire or isothermal annealing can be used to treat the forgings to obtain appropriate tissue and hardness, laying a good foundation for subsequent heat treatment. Precisely set process parameters: Heating temperature and time: Accurately according to the characteristics of gear material and heat treatment process requirements
- Effect of heat treatment process parameters on the mass stability of DFY250 gear reducerThere is currently no specific study on the impact of heat treatment process parameters on the mass stability of DFY250 gear reducer, but it can be analyzed from the perspective of the general impact of heat treatment process parameters on gear reducer, as follows: The influence of heating temperature and time on gear hardness and wear resistance: Heating temperature and insulation time are key factors affecting gear hardness. For example, during the quenching process, appropriately increasing the heating temperature and maintaining sufficient time can make the gear material fully austenitized, and a higher hardness can be obtained after quenching, thereby improving the wear resistance of the tooth surface. However, if the heating temperature is too high or the time is too long, it may cause coarse grains, causing the toughness of the gears to decrease and cracks are prone to occur. Effect on gear deformation: Uneven heating temperature will cause inconsistent expansion of various parts of the gear, resulting in thermal stress, and thus deformation. For the gears of the DFY250 gear reducer, the higher the carburization temperature, the thicker the carburization layer, and the gear deformation
- What factors should be considered when choosing a hard-toothed gear reducer or a soft-toothed gear reducerWhen 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 reducersTo 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 requirementsTo 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 reducerDifferent 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 maintain parallel shaft K57-Y2.2-4P-30.28-M1-0 gear reducerMaintaining the parallel shaft K57-Y2.2-4P-30.28-M1-0 Gear reducer, you can start from the following aspects: Check fasteners regularly: During the operation of the reducer, the fasteners are prone to loosening and need to be inspected regularly. If looseness is found, it should be tightened in time; if the fastener is damaged, it should be replaced in time to prevent the normal operation of the reducer due to loose connections, and even the components may fall off and cause safety accidents. Stay clean: Regularly clean dust and dirt on the surface of the reducer to prevent dust and debris from entering the interior and affecting its normal operation. At the same time, check whether the ventilation holes are unobstructed to ensure that the reducer has good heat dissipation and avoid excessive oil temperature due to poor heat dissipation, which affects the performance of the reducer. Check the lubricant condition: Check regularly whether the lubricant is sufficient and whether the oil is clean. Replace the lubricant regularly in accordance with the instructions. When replacing the lubricant, use the specified grade of lubricant and clean the old oil. If the amount of lubricating oil is insufficient or the oil quality becomes poor
- How to check the lubricating oil condition of K67-20-4KW-4P hard tooth surface reducerTo 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,
