Oil leakage in the P series planetary reducer will cause lubrication failure, thereby reducing transmission performance, exacerbating component wear, and eventually shortening the service life or even shutting down. 1. Directly lowering transmission performance. The reduction of lubricating oil will cause insufficient lubrication of meshing parts such as planetary gears and sun gears, increase frictional resistance, and significantly reduce transmission efficiency. Lack of oil leads to abnormal meshing clearance, intensified vibration and noise during operation, and unstable output torque, affecting the operation accuracy of the equipment. 2. Accelerated wear and damage of components. Without sufficient lubrication, gears and bearings are prone to dry friction, which can quickly lead to pitting, gluing or even ablation. In severe cases, tooth surface peeling may occur. Increased friction will cause the oil temperature to rise sharply, further aging the seals and remaining lubricating oil, forming a vicious cycle of 'oil leakage → oil shortage → more serious oil leakage'. 3. Shorten the life span and cause safety hazards. Long-term oil shortage operation will greatly shorten the life of the core components of the reducer, and equipment that can originally be used for thousands of hours may be scrapped early. A serious oil leak may cause Read More

To prevent the P series planetary reducer from leaking again, it is necessary to start from four aspects: 'sealing protection, installation accuracy, lubrication management, and daily maintenance' to form a full-process control to avoid leakage caused by seal failure or abnormal pressure. 1. Optimize the sealing system and build a solid foundation for leakage prevention. Select appropriate seals. The output shaft end is preferably a double-lip skeleton oil seal (with a dust-proof lip). The joint surface of the box is made of oil-resistant sealant (such as silicone or polysulfide) to avoid using aging and inconsistent-sized seals. When installing the seal, make sure there are no burrs or rust on the shaft surface, apply grease to the lip of the oil seal to avoid deformation during press installation, clean the joint surface of the box, apply sealant evenly and tighten the bolts symmetrically. For parts with frequent oil leakage, auxiliary sealing devices can be installed, such as adding an oil slinging ring at the shaft end, adding an anti-leakage groove on the joint surface of the box, or installing a sealing ring at the output shaft sleeve. 2. Strictly control the installation accuracy, reduce the stress on the seal, ensure that the installation surface of the reducer is flat and the base is fastened firmly. Read More

The core of reducing the vibration value of the NGW52-6 planetary gear reducer frame is to eliminate force imbalance, optimize assembly accuracy, solve component defects, and deal with it in a targeted manner from the four dimensions of installation, components, operation, and structure to quickly stabilize the vibration level. 1. Optimize the installation and assembly accuracy (basic and efficient) and re-level the installation surface to ensure that the flatness deviation is ≤0.03mm/m. Use spacers to adjust evenly to avoid tilting the machine base. Tighten the anchor bolts evenly according to the specified torque (refer to the equipment manual), install anti-loosening washers, and retighten regularly to prevent loosening. Calibrate input/output shaft coaxiality, control deviation ≤0.02mm, use elastic connection (such as plum blossom coupling) to absorb the impact caused by installation deviation. Check the mating surfaces of the machine base, end cover, and bearing seat to remove burrs and debris to ensure tight fit without gaps and avoid shock and vibration during operation. 2. Repair/replace failed internal components (from source Read More

To detect the vibration value of the base of the NGW61-3.15 planetary gear reducer, the core tools are classified according to 'Basic Measurement → Precise Analysis → Auxiliary Verification'. Priority is given to equipment that is portable and adapted to the working conditions of the reducer, as follows: 1. Core vibration measurement tools (direct measurement of vibration parameters) handheld vibration detector (vibration pen/portable vibration meter): the most commonly used tool, which can measure the effective value of the vibration speed (mm/s), acceleration, and displacement of the base, directly corresponding to GB/T 29531 and other standard thresholds, easy to operate, suitable for quick on-site investigation. Online vibration sensor + data collector: suitable for long-term monitoring. The sensor (such as a piezoelectric acceleration sensor) is fixed near the machine base bearing seat and anchor bolts to collect vibration data in real time. The collector can store and analyze trends and provide early warning of abnormal fluctuations. Spectrum analyzer: Precisely locate the vibration source and analyze the vibration frequency (such as gear meshing frequency, bearing Read More

The core materials of the NGW113-500 planetary gear reducer are divided according to component functions, mainly high-strength alloys and wear-resistant materials, taking into account load-bearing and fatigue resistance requirements. Materials of key components 1. Frame (box): HT250/HT300 gray cast iron is mostly used, and QT450-10 ductile iron is used in some heavy-load scenarios. The castings need to be aged to eliminate internal stress. 2. Planetary gear, sun gear, internal ring gear: core transmission parts are commonly made of 20CrMnTi, 20CrNiMo and other alloy structural steels, which are carburized and quenched + gear grinding to ensure hardness (HRC58-62) and wear resistance. 3. Planet carrier: Use 40Cr or ZG310-570 cast steel. The welded planet carrier is welded and formed from Q355B steel plate, which requires aging or quenching and tempering treatment. 4. Shafts (input/output shafts, planetary shafts): mainly 40CrNiMoA, 42CrMo, adjusted Read More

The core of preventing cracks in the NGW11-6.3 planetary gear reducer frame is to control stress, optimize assembly, match working conditions, and prevent the frame from bearing loads or stresses beyond the limit through multi-link management and control. Design and material optimization Calculate the strength of the machine base according to actual working conditions, appropriately increase the wall thickness or set reinforcement ribs at stress concentration locations (such as bolt holes and bearing seats). Materials that meet the tensile strength and toughness standards are selected, and the internal quality of the castings must be strictly controlled to avoid defects such as blisters and pores. After the machine base is cast, it is fully aged to eliminate residual internal stress and reduce the risk of cracking. The installation and assembly specifications ensure that the installation surface is flat and clean, and the anchor bolts are evenly tightened according to the specified torque to avoid over-tightening or uneven stress. Strictly calibrate the coaxiality of the input/output shaft, control the deviation within the equipment requirements, and reduce additional radial force. Avoid hard knocking during assembly to protect the mating surface of the machine base and prevent local stress deformation from causing stress concentration. Working conditions and operation control Read More
