‌Stop immediately to check and repair the heat sink to avoid equipment overheating and damage‌. Loose or damaged heat sinks of the JZQ500-50-2Z soft tooth surface reducer will significantly reduce the heat dissipation capacity, cause the temperature of the box to rise abnormally, accelerate the deterioration of the lubricating oil, cause severe wear of the gears and bearings, and even cause sudden equipment failure. In order to ensure the safe operation of the equipment, the following measures should be taken: ‌1. Stop the machine and cut off the power, and conduct visual and manual inspections. ‌Check whether the fixing bolts of the heat sink are loose, broken or missing, and whether the heat sink body is deformed, cracked or separated from the box; gently shake the heat sink by hand. If there is obvious shaking or abnormal noise, it is judged to be loose. ‌2. Use tools to accurately detect ‌ (1) Use a feeler gauge to measure the gap between the joint surface of the heat sink and the box. If ‌ exceeds 0.1mm‌, it means poor fit. (2) Use an infrared thermometer to detect the temperature difference between the box and the heat sink during operation. If the temperature difference is greater than 15°C, it indicates thermal conduction failure. Read More

Immediately deactivate and investigate the source of the fault. When the BWD8-29-30-6P cycloid reducer fails the load acceptance, it usually indicates that its output torque, temperature rise or operating stability does not meet the standards. The reasons need to be systematically investigated and corresponding measures taken. 1. Prioritize the troubleshooting of installation and working conditions (accounting for more than 60% of heating/overload problems) 1. Check the coaxiality and connection status of the shaft system. Reducers in electronic equipment have extremely high installation accuracy requirements. If there is a coaxiality deviation between the input/output shaft, the motor, and the load end, it will cause uneven stress on the internal transmission components and increase friction, causing overheating or weak output. (1) Use a dial indicator to detect the runout at both ends of the coupling and control it within 0.05mm. (2) Tighten all connecting bolts to ensure there is no looseness. 2. Confirm whether the actual load exceeds the limit. The rated output torque of BWD8-29-30-6P is approximately ‌300N·m‌. If the actual load exceeds 1.2 times this value (i.e. Read More

Practical plan to reduce the risk of reducer box rupture through daily maintenance. 1. Strictly control lubrication management to avoid dry grinding and high-temperature expansion and cracking. Regular inspection of oil level: Check the oil level of the sight glass every day and keep it at the center line of the standard scale; prevent dry grinding due to lack of oil (internal gears and bearings are sintered at high temperatures, and the shell expands and cracks when heated), and excessive oil injection (excessive internal pressure, cracking of end cover and box joints). Oil matching + regular oil change: Select the original factory-specified gear oil according to the working conditions, and shorten the oil change cycle in high-temperature/dusty and heavy-load environments; avoid mixing inferior oil and deteriorated oil to prevent oil film failure from causing internal overheating, component jamming and cracking of the box. Unblock the breather valve regularly: Clean the breather cap/ventilator valve of the reducer every week to prevent blockage, which may lead to poor heat dissipation and exhaust in the box, high pressure, and long-term high pressure to crack the welds and weak parts of the box. 2. Fastening and sealing maintenance to prevent external force from loosening and cracking bolts. Tighten the bolts in stages: 1 month after new machine/overhaul, retighten the box connecting bolts.

BLEY2715-5133-0.75KW (cycloidal pinwheel reducer) Internal impurities enter mainly through two major ways: external intrusion and internal generation. The following are the specific paths: 1. External intrusion (the main way) 1. Ventilation/breathing device (ventilator cap/respirator) The internal pressure changes when the reducer is running. It exchanges with outside air through the ventilator cap, and dust, water vapor, and tiny particles enter directly with the air. The ventilation cap filter is damaged, missing, or blocked, and the protection fails. 2. Shaft end seal failure (input/output shaft oil seal) skeleton oil seal is aged, hardened, lip damaged, installed skewed, dust, water vapor, and external oil seep into the gap between the shaft and the oil seal. The journal is worn and scratched, damaging the sealing mating surface. 3. The joint surface of the box and the sealing defects include the upper and lower boxes, end covers, observation holes and other sealing gaskets that are aged, damaged or missing, or the sealant is unevenly applied and has gaps. The processing accuracy of the box joint surface is not good Read More

Common reasons why ZSY315-80-2 hard-toothed cylindrical gear reducer cannot start 1. Mechanical stuck/overload (highest) 1. Back-end load is locked and stuck: driven equipment such as belt conveyors, scrapers, ball mills, etc. are blocked, bearings are ablated, and debris is stuck. The reducer cannot carry the load and cannot rotate when powered on. 2. Internal mechanical failure of the reducer: gears at all levels have chipped teeth, broken teeth, and tooth surfaces are severely glued and stuck; the high-speed shaft/intermediate shaft/low-speed shaft bearings are broken, the cage is stuck, and the rollers are falling off and locked; internal couplings, flat keys are shearing and shifting, and splines are stuck; lubrication failure leads to dry grinding and sintering of gears and bearings, and viscosity and jamming inside the cavity. 3. Serious deviations in installation alignment: the coaxiality of the motor and the reducer is out of tolerance, the base feet are loose and offset, the bearings are subject to excessive radial force, and the operation is stiff and stuck. 4. The brake is not released: the supporting brake, electromagnetic brake, and backstop are stuck and will not be released, and the machine is mechanically locked and cannot rotate. 2. Motor and electrical Read More
