• What are the common faults in the internal gear transmission system of CJY160-160-LZ-5.5KW reducer?

  CJY160-160-LZ-5.5KW is a gear reduction motor integrated model (adapted to 5.5KW motor, LZ Vertical installation), its internal gear transmission system is mainly composed of involute cylindrical gears. Faults are mostly concentrated in the three core parts of the gear body, meshing pairs, and shaft system coordination, and are mostly caused by installation deviation, lubrication failure, abnormal load, and fatigue wear. The following is a summary of high-frequency faults, their characteristics, and causes, and is presented in a structured plain text: 1. Gear tooth surface wear (abrasive wear/ Adhesive wear) Characteristics: Uniform wear marks and grooves appear on the tooth surface. In severe cases, the tooth thickness becomes thinner and the meshing gap is too large, accompanied by increased operating noise and reduced transmission efficiency. Adhesive wear will cause tooth surface adhesive, metal peeling, and local high-temperature ablation marks. Causes: Insufficient grease/lubricating oil level, deterioration of oil quality (mixed with iron filings/dust), mismatched lubrication model; rupture of the oil film on the tooth surface under low speed and heavy load; casing failure during installation

• How to judge whether the thermal expansion gap of FAF87-32r/pm-7.5KW reducer is appropriate

  To determine whether the thermal expansion gap of the FAF87 reducer is appropriate, the core is to measure the actual gap value of the key matching pair in the cold and hot states, and compare it with the design specification or empirical value. The following are the specific operation steps: 1. Core measurement method ‌static measurement‌: After stopping the machine for cooling, use a feeler gauge or dial indicator to measure the initial clearance of key parts such as gear backlash and bearing clearance. ‌Dynamic monitoring‌: Run the equipment to thermal equilibrium (oil temperature is stable), use an infrared thermometer to monitor the temperature of key points, and use a laser alignment instrument or vibration sensor to monitor the axial movement. ‌Thermal expansion calculation‌: Calculate the theoretical gap change based on the linear expansion coefficient of the material (such as steel about 12×10⁻⁶/℃) and the temperature difference, and compare it with the actual measured value. 2. The key inspection part ‌gear meshing side clearance‌: measured with the lead wire method or feeler gauge, the hot state gap should be slightly smaller than the cold state (usually reduced by 0.01-0.05mm). ‌Bearing clearance‌: Measure the bearing inner ring and shaft

• What factors are related to the quality of reducer seals?

  The quality of reducer seals directly determines its sealing effect, service life and anti-leakage ability. It is dominated by the three core elements of raw material material, production and manufacturing process, and structural design. At the same time, the original factory quality control standards, adaptability design, and transportation and storage conditions will also directly or indirectly affect its actual use quality. , various factors are interrelated and jointly determine the adaptability and stability of the seal under the complex working conditions of high temperature, high speed, vibration and oil pollution of the reducer. The specific impact details are as follows: 1. The raw material material is the basis of the quality of the seal, which directly determines its oil resistance, temperature resistance, wear resistance, aging resistance and compression deformation resistance. Mainstream rubber seals (skeleton oil seals, O-rings), high-quality products will use special rubber materials such as virgin nitrile rubber and fluorine rubber, with antioxidant and anti-wear additives. The rubber material has high purity, precise formula, and the Shore hardness is controlled within a reasonable range of 70-85 degrees, which not only ensures the fit of the sealing lip, but also reduces friction.

• 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

  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
