How to choose the bore diameter of the anchor bolt of the soft tooth surface ZL42.5-28-2 reducerThe selection of anchor bolt diameter of ZL reducer requires comprehensive consideration of multiple factors. The following are specific methods and key points: According to the bolt diameter: Generally speaking, the anchor bolt diameter should be 10-20mm larger than the bolt diameter. For example, if the anchor bolt diameter is M20, the aperture can be selected between 30 and 40mm. This gap facilitates smooth insertion of anchor bolts, and can also provide a certain amount of adjustment during the installation process to ensure the accurate installation position of the reducer. Reference reducer specifications: different specifications The anchor bolt hole diameter requirements for ZL reducers are also different. Due to the large reducer's load, the anchor bolt specifications are correspondingly larger and the aperture will be larger. Small reducers are the opposite. For example, ZL - The anchor bolt diameter of the 250 reducer may be around 40 - 50mm, while the anchor bolt diameter of the ZL - 50 reducer

What other measures can prevent the wear of the gears of the KA87-102.71-3K reducerKeep the working environment clean: Clean the dust and debris around the reducer regularly to prevent them from entering the reducer, as dust and impurities may aggravate the wear of the gears. Control temperature and humidity: Avoid the reducer in a high-temperature and high-humidity environment. High temperatures will cause the lubricant performance to slow down and accelerate gear wear. The temperature can be controlled by installing a heat dissipation device or improving ventilation conditions; high humidity may cause rust of the gears, and desiccants can be used to keep the environment dry. Optimize equipment design and rational design of gear parameters: During the design stage, according to the working conditions of the reducer, the gear module, number of teeth, tooth shape and other parameters are reasonably selected to improve the gear's load-bearing capacity and wear resistance. For example, appropriately increasing the modulus of the gear can improve the strength and wear resistance of the gear.

How to thoroughly clean old oil and impurities when replacing lubricating oil with Flender reducerWhen replacing the Flender Flander reducer lubricant, thoroughly clean old oil and impurities can be carried out according to the following steps: Stop the preparation work in advance, let the reducer cool naturally to room temperature, and prevent hot oil from burning. Prepare new tools and materials such as lubricants, special wrenches, oil drain containers, funnels, filters, wipes, cleaning agents, etc. that meet the requirements. Discharge oil and find the oil drain hole of the reducer, which is usually located at the bottom of the reducer. Unscrew the oil drain screw plug and drain the old oil into the oil drain container. In order to drain the old oil as clean as possible, the output shaft of the reducer can be rotated slowly so that the oil attached to the gears and shafts can flow back to the oil pan and discharged. After the old oil is basically discharged, use a wipe cloth to clean the oil stains and impurities around the oil drain holes to prevent impurities from entering the reducer during subsequent operations. You can rinse the oil drain hole and the inside of the oil pan with a detergent, rinse the remaining oil stains and impurities, and then discharge the cleaning agent and residual impurities together.

What is the problem if the SEW reducer leaks oil but the oil level is normalSEW 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

SEW reducer lubricating oil emulsified moisture intrusion treatment solutionWhen 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
