• How to extend the service life of ZQA750-48.57-1-Z soft tooth surface gear reducer sealing structure

  To extend the service life of the ZQA750-48.57-1-Z reducer seal structure, you can start by choosing high-quality seals, optimizing installation and maintenance, etc. The specific methods are as follows: Choose high-quality seals: The seals on the market are of uneven quality, and products with reliable quality and durability should be selected. High-quality seals have better elasticity and wear resistance, and can maintain a stable sealing effect during long-term operation. For example, seals made of fluoroelastomer (FKM) and modified polyurethane can be selected, which have good aging resistance, mechanical strength and wear resistance. Reasonable design of seal structure: a double-lip sealing design can be adopted, adding a layer of lip to the traditional single-lip seal to form double protection and improve sealing performance. At the same time, the fit between the seal ring and the shell is optimized to ensure that the seal can maintain a good sealing effect under the pressure state. Optimize the working environment: Try to ensure that the reducer is dry, ventilated and has a suitable temperature

• ZQA500-15.75-1 How often does the sealing structure of the soft tooth surface reducer need to be replaced?

  ZQA500-15.75-1 There is no fixed standard for the replacement cycle of the sealing structure of the soft tooth surface reducer. It is usually affected by factors such as working environment, load conditions, etc., and it needs to be determined in combination with multiple factors. The following is a specific analysis: Working environment: If the reducer is in a clean and dry environment, the service life of the sealing structure is relatively long and may be replaced every 2-3 years. If the working environment is humid, dusty or corrosive, the sealing structure is prone to aging and damage and may require replacement every year or more frequently. Load conditions: Under light load conditions, the sealing structure has less wear and a longer service life. Under heavy load conditions, the sealing structure bears greater pressure and friction, wear faster, and the replacement cycle will be shortened accordingly, and it may require more frequent replacement. Maintenance: If you can check the status of the sealing structure regularly, find leakage, deformation or aging problems in a timely manner, and replace lubricant and clean the filter regularly, it can be extended.

• How to determine whether the vibration of the gear reducer box exceeds the standard

  To determine whether the vibration of the gear reducer case exceeds the standard, you can start from the following aspects: measuring vibration parameter measurement tools: use professional vibration measurement instruments, such as vibration testers, accelerometers or speed sensors. The linear range of speed sensor measurements is usually 10 to 2500Hz, and the accelerometer measurement range is generally no more than 10kHz. Measurement position: The vibration of the box should be measured at a part of the box with better rigidity (such as the bearing seat). The measurement must be performed in three mutually perpendicular directions, two of which must be located in a plane perpendicular to the axis of rotation of the gear, preferably a horizontal plane or a vertical plane. Measurement conditions: According to GB/T 6404.2 - 2005, the gear device shall operate at a rated speed during the test. If used for speed variable conditions, the test shall be carried out under the arithmetic average value within the speed range.

• How to perform accuracy detection after the gear reducer is assembled

  After the gear reducer is assembled, accuracy detection can be carried out from the following aspects: 1. Basic parameter verification: Check the nameplate information of the reducer, including model, speed ratio, rated power, torque range, etc. At the same time, check the level and stability of the equipment installation foundation, and use an electronic level with an accuracy of 0.02mm/m to measure. If there is settlement or offset in the foundation, it needs to be corrected first. 2. Adjust the horizontality and coaxiality: Use an electronic level to measure the horizontal deviation at the three positions of the reducer input shaft, the box base, and the output shaft installation surface, and adjust the thickness of the base gasket to ensure that the overall horizontal error is ≤0.05mm/m. The laser centering instrument detects the coaxiality between the input shaft and the motor shaft, the output shaft and the load end. It is recommended that the radial deviation be controlled within 0.05mm and the angle deviation is ≤0.1°. 3. Gear meshing accuracy detection: Contact spot detection: Blue Dan coloring method can be used to apply the blue mark paint evenly to small

• What is the reason for abnormal heating of the KAF97-5.3-A-FL4520 gear reducer

  KAF97-5.3-A -FL4520 The main reasons for abnormal heating of gear reducers are as follows: 1. Lubrication problem. Insufficient lubricating oil: insufficient lubricating oil inside the reducer will increase friction between gears, bearings and other components, generate too much heat, and lead to excessive temperature rise. Poor quality of lubricant oil: Use of unqualified quality, aging or deteriorated lubricant will become worse, increasing friction between parts, and causing abnormal heating of the reducer. 2. Load problem Overload operation: The load the reducer bears exceeds its rated value, the friction between gears and bearings and other components will increase sharply, heat accumulates in large quantities, and the temperature will rise rapidly. Frequent start and stop: Excessive start and stop operations will cause the reducer to bear additional load, resulting in higher temperature rises. Load fluctuations: The load is unstable and frequently changes, which will cause the reducer to withstand instantaneous overload, thereby increasing temperature rise. 3. The ambient temperature is too high: if the reducer working environment temperature

• What are the sealing structures of ZQA400-IV-1/2 soft tooth surface gear reducer?

  ZQA400 - IV - 1/2 Common sealing structure types for soft-toothed gear reducers are as follows: 1. Felt ring seal: compact installation size, low disassembly and assembly technology requirements, and low cost. However, it wears fast, requires the linear speed of the shaft, and has a short service life. It is rarely used in the shaft end seal of this type of reducer. 2. Gap throttle groove sealing: It uses the tortuous gap throttling effect to produce a sealing effect. It is a non-contact seal with a long working life and can be used in high-speed and low-speed conditions. However, the effect of using alone is not ideal and is often used as an auxiliary sealing method. 3. Skeleton oil seal seal: Use spring coil to tighten the seal, so that the lip can generate appropriate radial force on the shaft, and can automatically compensate after the lip wear to ensure good sealing performance. The sealing structure is simple, compact, has good sealing performance, and has certain adaptability to the equipment vibration and eccentricity of the shaft diameter. However, the dimensional tolerances of shaft diameter, oil sealing slot, surface roughness and the surface of the shaft

• What factors will affect the gear machining accuracy of SAF97-60-0.75KW reducer

  The following are some factors that affect the machining accuracy of the gears of the SAF97 - 60 - 0.75KW reducer: Machine tool accuracy: Spindle rotation accuracy: radial circular jumping, end surface circular jumping and axial jumping of the working parts at the front end of the spindle will cause eccentricity and tooth shape errors to produce machined gears. For example, the roundness error of the spindle journal, the verticality error of the bearing axial positioning surface and the spindle axis, etc., will affect the gear processing accuracy. Guide rail guidance accuracy: Accuracy indicators such as linearity and parallelism of the guide rail affect the relative motion accuracy between the tool and the tooth blank. If there is an error in the guide rail, it will cause tooth direction errors and so on during the processing of the gear. Transmission accuracy of transmission chain: The manufacturing errors and assembly errors of various transmission elements in the transmission chain, such as gears, racks, worm gears, worms, etc., will accumulate and transfer to the machined gear according to the transmission ratio, affecting the gear splitting accuracy and motion accuracy of the gear. Fixture: Positioning accuracy: Fixture determination
