• What are the dangers of adding too much or too little lubrication to the WPDX80-30-A worm gear reducer?

  Improper grease filling, whether too much or too little, will cause serious harm to the WPDX80-30-A worm gear reducer. The core is accelerating wear, causing overheating, causing leakage, and ultimately shortening the life of the equipment. 1. The hazards of too little grease: Insufficient lubrication and increased wear: An effective oil film cannot be formed, and metal parts such as gears and bearings are directly rubbed against each other, resulting in tooth surface wear, pitting, gluing, bearing raceway scratches, increased clearance, reduced transmission accuracy and noise. ‌Poor heat dissipation and temperature rise‌: Lubricating oil has a heat dissipation effect. When the amount of oil is insufficient, the heat cannot be dissipated in time, resulting in ‌oil temperature rising sharply‌, the viscosity of the lubricating oil being reduced, and the lubrication performance further deteriorating, forming a vicious cycle. ‌Accelerated component failure‌: Under high load and high speed, wear will become more serious, which may lead to sudden failures such as gear breakage and bearing burnout. 2. The dangers of adding too much grease - increased oil churning losses

• How to solve the problem of poor adaptability of the K97-27.9-15KW reducer splash lubrication system to the installation posture and working conditions

  The K97-27.9-15KW reducer is a hard-tooth surface model with medium to high power of 15kW and a transmission ratio of 27.9. The sensitivity of the splash lubrication system to the installation posture and working conditions is rooted in the passive structure that lubrication relies on gear oil. Based on the parameter characteristics of this model, the adaptability of the system can be improved through three types of measures: installation optimization, lubrication system modification, and working condition adaptation adjustment. The specific plans are as follows: 1. Adaptation optimization plan for installation attitude deviation. The splash lubrication of this model of reducer is adapted to horizontal installation by default. If non-standard installation such as tilted or vertical is required, the oil level and oil guide structure must be adjusted to ensure the gear oil and bearing lubrication effect. 1. Accurately check the oil level for non-horizontal installations (1) If inclined installation is used (inclination angle ≤ 15°): the immersion depth of the low-speed gear must be recalculated to ensure that the immersion depth of the tooth root is still 1/3~1/2 of the tooth height. Additional auxiliary equipment can be added to the side of the box

• What effect does the working environment temperature of ZL35-12-I gear reducer have on the motor power?

  The working environment temperature of the ZL35-12-I gear reducer mainly changes the effective output power of the motor indirectly or directly by affecting the motor heat dissipation efficiency and the performance of the reducer lubricating oil. The specific effects are as follows: 1. The impact of high temperature environment (ambient temperature > 45°C) on motor power 1. The heat dissipation efficiency of the motor decreases and the effective power attenuates. The rated power of the motor is based on the standard ambient temperature (25°C) Calibrated, when the ambient temperature exceeds 45°C, the temperature difference between the motor shell and the environment decreases, the heat dissipation speed slows down, and the winding temperature rises rapidly. In order to prevent the winding insulation layer from aging due to high temperature, the allowable output power of the motor will be forced to be reduced. (1) Empirical rule: for every 10°C increase in ambient temperature, the effective output power of the motor will decrease by 8% to 12%; when the temperature reaches 60°C, the power attenuation can reach 20% to 30%. (2) Impact on ZL35-12-Ⅰ

• How to adjust the meshing gap between the cycloidal wheel and the pin gear shell of the BLEY3922-5133-0.55KW reducer

  Adjust BLEY3922-5133-0.55kW The meshing gap between the cycloid wheel and the pin gear shell of the cycloidal pin wheel reducer is a key operation to ensure smooth transmission, reduce noise, and extend the service life. The standard range of the meshing gap of this model is 0.15~0.30mm. The specific adjustment steps are as follows: 1. Gap measurement and marking before disassembly. First, manually rotate the input shaft, feel the rotation resistance and record the abnormal position; then use a feeler gauge to measure the gap between the cycloidal wheel tooth top and the pin tooth pin, and mark the area where the gap is too large or too small to provide reference for subsequent adjustments. If the reducer has a double cycloid structure, alignment marks must be made on the two cycloid wheels, eccentric sleeve, and output flange to avoid assembly phase errors after disassembly and affecting the gap adjustment accuracy. 2. Disassemble the core components and clean and inspect them. Remove the motor, input shaft end cover, output flange, pin bushing and pins in sequence, and take out the two cycloid wheels. Please note that it is forbidden to knock the cycloidal wheel and pin teeth during disassembly.

• How to control the start, stop and operating load of the motor supporting the BLEY4527-595-4KW cycloidal reducer

  The core of controlling the start, stop and operating load of the motor supporting the BLEY4527-595-4kW cycloidal pinwheel reducer is to match the motor characteristics and the working condition requirements of the reducer to avoid start-stop impact damage to transmission components and overload operation to shorten the life of the equipment. Specifically, precise control can be achieved through the three dimensions of electrical control, mechanical protection, and working condition optimization. The operation method is as follows: 1. Smooth control of motor start and stop (reduce impact load). The reducer has a reduction ratio of 595. It is a large reduction ratio and low-speed model. The instantaneous impact when the motor starts and stops will be amplified, which can easily cause the cycloid wheel and pin tooth pin to break. The following electrical and operating methods need to be used to buffer the impact: 1. Electrical control scheme (preferred) (1) Install a frequency converter for speed control starting with a matching 4kW motor. Use a general-purpose frequency converter (adaptive motor power ≥5.5kW to avoid overload), and set a soft start/ Soft stop parameters: Set the start time to 5~10s and stop
