Root cause one: lubricant failure or improper filling. If the lubricating oil is not replaced for a long time, it will deteriorate, the viscosity will decrease, and an effective lubricating layer will not be formed. Dry friction of the gears will generate a lot of heat. At the same time, the transmission resistance will increase, and the power loss will increase sharply. Too much oil will lead to poor internal heat dissipation and excessive pressure, while too little oil will aggravate friction and heat. Solution: Replace with new special gear oil and fill it quantitatively according to the standard scale. Root cause two: gears and bearings wear and age. After the equipment has been used for a long time, the gears wear, the bearing clearance becomes larger, the transmission accuracy decreases, and the running resistance increases. Not only does the body heat up, but the power transmission is insufficient, and the force cannot be exerted. If there is slight wear, the clearance can be adjusted and lubrication added. If the wear is serious, the gear bearing assembly needs to be replaced. Root cause three: long-term overload work. Frequent jamming and overfeeding put the reducer in an overload state for a long time, the internal load exceeds the standard, the temperature rises rapidly, and the transmission efficiency drops significantly. Long-term overloading will accelerate the accessories Read More

The following is an in-depth analysis and corresponding prevention strategies: 1. Cause analysis: The material quality and heat treatment process of the spindle or reducer shaft directly determine its fatigue resistance. If the selected materials are unreasonable (such as internal defects such as pores and inclusions), or the heat treatment is not in place (such as surface hardness not up to standard and core toughness poor), the fatigue resistance of the shaft will be greatly reduced. For example, some cast spindles are loose inside, like 'roasted steamed buns', and are prone to fatigue cracks under alternating stress; while some shafts are not surface treated after quenching and tempering, resulting in surface hardness far lower than the design requirements, accelerating early fatigue fracture. 2. Prevention strategy: Upgrade materials and forming processes: Prioritize the use of high-strength alloy steels (such as 42CrMo, 18CrNiMo7-6, etc.), and use full forging processes instead of castings. Forging can refine metal grains, tighten the structure, eliminate internal pores, and greatly improve toughness and impact resistance. Optimize heat treatment process Read More

1. Strengthen daily maintenance and reduce failure losses. Standardized maintenance is the basis for stabilizing equipment accuracy and reducing sudden shutdown losses. Basic cleaning and lubrication: Clean and lubricate before each shift ends, focusing on cleaning impurities in slide rails, gears and other parts and adding special lubricating oil to eliminate stuck and abnormal noise. Oil and filter element management: Check the oil level in the tank every week to ensure the oil is clear; replace the hydraulic oil and filter element regularly to prevent oil circuit blockage and hydraulic valve sticking. Implement the inspection system: assign the responsibility for equipment inspection to one person, and 'look, listen, touch, and check' before starting the machine every day, promptly discover and deal with minor problems such as loose screws and oil leakage, and nip failures in the bud. 2. Implement low-cost transformation to extend the life of the equipment. For old reducers, speed improvements and cost reductions can be achieved through 'micro-innovation' without replacing the entire unit. Partial replacement and tooth number optimization: Under the premise of keeping the center distance and module unchanged, only changing the input stage gear shaft gear ratio can effectively improve the output.

1. Hardware general sheet metal industry: mainly bending thin plates and ordinary plates, with medium precision requirements, high mass production frequency, and cost sensitivity. Adaptation plan: Use a conventional worm gear reducer, which is cost-effective, easy to install, and comes with a self-locking function, which fully meets the bending needs of ordinary hardware and reduces equipment investment costs. 2. Auto parts processing industry: Processing door, chassis, and interior sheet metal parts requires extremely high dimensional consistency and bending accuracy, large batches of workpieces, and a high degree of standardization. Adaptation plan: Use a precision planetary reducer or a two-speed reducer. The transmission has no gap and runs smoothly. It can accurately control the bending angle and ensure the consistency of batch workpiece forming. 3. Electronic precision sheet metal industry: processing mobile phone casings, electrical appliance casings, and precision thin plate accessories. The plates are thin and the precision requirements are strict. Small errors will cause the workpiece to be scrapped. Adaptation plan: high-precision micro planetary reducer, low noise, zero gap, fast response, suitable for precision CNC bending equipment, Du Read More

1. Transmission efficiency Transmission efficiency directly reflects the energy consumption level of the reducer and is the core indicator for measuring its performance. During testing, the torque and rotational speed at the input and output ends are usually collected through sensors, and the ratio of input power to output power is calculated. High-quality reducers usually have high transmission efficiency under rated working conditions (for example, a single-stage cylindrical gear reducer can reach more than 98%). In addition, as the output torque increases, the transmission efficiency usually shows an upward trend and reaches the highest value when reaching 100% of the rated torque. 2. Temperature rise and temperature Temperature rise detection is one of the most basic and important items in the load test. During the test, the oil pool temperature, bearing seat temperature and ambient temperature need to be continuously monitored. According to national standards, when the reducer continuously operates to a thermal equilibrium state under rated operating conditions, its temperature rise and maximum oil temperature must be controlled within the allowable range (for example, the temperature rise does not exceed 40K, and the maximum oil temperature does not exceed 95°C or 10 Read More

1. Source control: High-precision blanking and bevel processing of structural parts are the source of ensuring high-precision operation and long-lasting reliability of the entire machine. It is recommended to use laser cutting process to ensure that the cutting material is flat, smooth and has minimal deformation. At the same time, it is necessary to ensure that the laser-cut bevel angle has zero deviation and the edges are smooth and clean. This can make the strip welding workpieces closely fit and form a weld with almost zero gap, so that the welding seam can be made uniform and consistent, avoiding the hidden dangers of repair welding and partial welding caused by rough blanking, and laying a solid foundation for welding strength and overall rigidity. 2. Process coordination: One-time positioning and datum control are used in the processing of the machine base and reducer mounting seat. Try to achieve one-time positioning to directly complete the processing of beveling, arc cutting and positioning holes. In this way, the verticality and dimensional accuracy of the end face can be stably controlled at the millimeter level, ensuring that the datum plane is perfectly aligned. This can physically eliminate abnormal vibrations caused by assembly stress and pave the way for long-term stable service of the entire machine. Read More
