SEW reducer leaks oil but the oil level is normal. There may be the following reasons: sealing problems. The sealing is aging or damaged: After long-term use of seals, seals such as seals, oil seals, etc., will age, cracks or deformation due to temperature changes, mechanical wear, etc., resulting in a decrease in sealing performance and oil leakage. Improper installation of seals: If the seal is not operated according to the specifications when installing the seal, such as the seal being damaged or the sealing surface is not aligned, even if the oil level is normal, it will cause a tight seal and oil leakage. Box-related problems Box deformation: When the reducer is manufactured, if the casting is not annealed or aging, the internal stress is not eliminated, and deformation may occur during use, resulting in gaps and oil leakage. There are trachoma or gaps in the box: the castings are of poor quality and there are trachoma or gaps in the box. Lubricating oil will seep out of these weak places, but the oil level may not drop significantly when a small amount of leakage is leaked. Poor oil return: If there is no oil return tank in the box, or the oil return tank is unreasonable and blocked, it will fly Read More

When the SEW reducer has lubricating oil emulsification phenomenon and is caused by moisture intrusion, it can be solved from the two aspects of cause investigation and treatment plan. The specific details are as follows: Cause investigation and seal aging or damage: the reducer is running for a long time, and the seal is such as oil seal O The rings and other types will gradually age and harden, lose elasticity, and cracks and breakage, causing external moisture to enter the internal respirator to be blocked or failed: the function of the respirator is to balance the pressure inside and outside the reducer. If the respirator is blocked by dust and impurities, or it is damaged and failed, when the internal temperature of the reducer changes, it is impossible to breathe normally, which easily forms negative pressure, sucking the external humid air, which leads to moisture accumulation and leakage at the welding or bonding surface of the box: During the manufacturing process of the reducer, the welding may have defects such as sand hole pores, or after long-term use, the sealant on the joint surface of the box aging and cracking, giving the moisture a chance to penetrate into the operating environment of the equipment. If the reducer is in the Read More

XWD9-87-11KW reducer is a cycloidal needle wheel reducer. Compared with other types of reducers, it has the following advantages: the reduction ratio is large: the first-stage transmission reduction ratio is 9-87, the double-stage transmission reduction ratio is 121-5133, and the multi-stage combination can reach tens of thousands, which can meet various different reduction needs. Compared with some ordinary gear reducers, the structure is simpler and compact when achieving a large reduction ratio: the needle tooth meshing system rolling friction, meshing The combined surface has no relative sliding, and the first-stage deceleration efficiency reaches 94%. In some equipment that requires long-term operation and energy consumption requirements, it can effectively reduce energy consumption costs, which is much higher than worm gear and worm reducer, etc., and the operation is much smoother and lower noise: there are many pairs of teeth that are contacted at the same time during operation, with large overlap, stable operation, strong overload capacity, low vibration and noise, and various specifications of the machine are low noise, suitable for places with high requirements for working environment noise, such as some precision instruments Read More

GR17 - 0.55KW - 4P - 13.84 The following precautions are given to the daily maintenance of helical gear reducers: Check whether the installation bolts are loose, whether there are cracks or deformations of the installation base of the reducer. If there is looseness, tighten the bolts in time. If there is any problem with the base, it must be repaired or replaced in time to ensure that the reducer is installed firmly and avoid vibration and noise increase, or even damage to the appearance of the reducer. Check the appearance of the reducer: Check whether there are cracks in the reducer shell, and whether there is oil leakage at the sealing surfaces of each joint surface. If there is cracks in the shell, it may affect its strength and sealing, and it needs to be dealt with in a timely manner; leaking oil will cause the amount of lubricating oil to decrease and affect the lubricating effect. Find out the cause of leakage and repair the sealing part Lubricating oil inspection: Check the oil level of the lubricating oil regularly to ensure that the oil level is in the normal range, which will cause the gears and bearings and other components to be insufficiently lubricated, and accelerate the grinding.

When cleaning the internal part of the reducer, the following precautions are given: Safety First, be sure to cut off the power supply of the reducer before cleaning, and make sure that the power supply will not be accidentally turned on during the cleaning process. You can hang the warning sign of 'Inspection, please do not close the switch'. If necessary, arrange a dedicated person to monitor and wait for the reducer to completely stop running and cool before cleaning operation to prevent scalds and accidental start of the equipment, keep records and marks. Before disassembling the reducer shell and internal parts, carefully observe and record the installation position and connection method of each component. If necessary, take a photo or draw a simple diagram to ensure that some important parts, such as gear shaft bearings, can be marked with a marking pen or label to avoid errors during installation.

R117 reducer has the characteristics of high transmission efficiency, high torque and good stability, and is widely used in different equipment in many fields. The following are some common application scenarios: Metallurgical industry: In the feeding system of blast furnace, it can drive conveyor belts and hoists to transport ore and coke and other raw materials into the transmission system of the internal steel rolling mill in the blast furnace. It can accurately adjust the speed and torque of the rolling roll according to the requirements of the rolling process to ensure the rolling quality and production efficiency of steel. The ore conveying system used in mines, such as belt conveyor scraper conveyors, etc., can also be used in the crushing equipment of mines from underground or mine areas to designated locations on the ground, such as jaw crusher cone crusher, etc., to provide strong power for crushing ores, so that the equipment can efficiently crush large pieces of ores into small pieces of chemical industry: In reactor mixing equipment, the speed of the stirring paddles can be accurately controlled according to the requirements of chemical reactions.
