BWD45-87-7.5KW The output shaft of the cycloid reducer may be caused by the following overload conditions: Selection improper results in long-term overload: If various factors in actual work are not fully considered at Selection, the rated output torque of the selected reducer does not match the actual required torque, it may cause the reducer to be in a long-term overload state. For example, in some working scenarios where frequent start, braking or large impact loads are present, if only the conventional average load is Selection and sufficient torque margin is not reserved, then even under normal working loads, the reducer may fail the output shaft due to the inability to withstand these additional impacts. Equipment failure causes sudden increase in load: During operation, some failures may occur, resulting in sudden increase in load of reducer, exceeding its ability to withstand. For example, the mechanical components of the driven equipment are stuck or stuck, causing the output shaft of the reducer to rotate when the output shaft of the reducer is rotated. Read More

To determine whether the output shaft break of the cycloid reducer is caused by overload, you can start from the following aspects: Check the fracture shape: Plastic deformation characteristics: If the output shaft material is a plastic material, there will generally be obvious plastic deformation when overloaded and broken, such as the diameter of the shaft may become partially thinner and there will be necking near the fracture. Fracture texture: brittle fracture caused by overload, the fracture roughness is relatively consistent, there are obvious marks on the surface, and the marks point to the origin of the damage; if the plastic material is under very rapid and severe overload, it may also show a failure mode similar to the brittle material, the crack may show a 45° inclination, and the keyways are significantly deformed. Analyze the operation records and working conditions: Load changes: Check the equipment operation records to understand whether the load borne by the reducer suddenly increases and exceeds the rated load before the output shaft breaks, such as whether additional heavy objects are suddenly added to the transmission system, or working resistance Read More

For RXF71-3.25-4KW reducers that have shortened the maintenance cycle, the following remedial measures can be taken: Strengthen lubrication management to check the lubricant: Check the oil level and quality of the lubricant regularly. If the oil becomes turbid, impurities or has expired, it should be replaced in time. Make sure to use lubricating oil suitable for this reducer. Oils of different grades are not allowed to be mixed. Shorten the oil change cycle: If the crude oil change cycle is replaced every 5,000 hours or the oil pollution exceeds the standard, consider shortening it to every 3,000 hours or less to ensure the performance of the lubricant. Check load condition: Regularly evaluate the reducer’s load to ensure it operates within the rated load range. Avoid long-term overload or impact load. If overload is found, you need to adjust the load in time or replace the appropriate reducer with specifications. Reinforced parts inspection and maintenance inspection gear: Check the wear of the gear regularly to check whether there are abrasions, glues, and significant wear on the tooth surface. Read More

To improve the processing accuracy of the RXF97-7.5-358 hard-tooth gear reducer, you can start from the following aspects: optimizing material selection and heat treatment to select high-quality materials: according to the working conditions and performance requirements of the reducer, select high-strength and wear-resistant materials, such as carburized steel, alloy steel, etc., such as 40Cr, 45Mn, etc. At the same time, factors such as material processability, cost, fatigue strength, hardness and toughness should be considered. Optimize heat treatment process: improve the microstructure of the material through normalization process, improve toughness and plasticity; use tempering treatment (quenching + low-temperature tempering) to achieve the best matching of material strength and toughness. For gears with high surface hardness requirements, surface treatments such as carburizing and nitriding can be carried out to form a hard and wear-resistant seepage layer on the surface of the gear to improve wear resistance and fatigue resistance. Precise control of cutting processing and optimize cutting parameters: cutting speed, feed quantity and back-feeding tool quantity are key parameters that affect processing accuracy Read More

WPO175-15 Common noise problems in worm gear reducers are as follows: Gear-related problems Gear wear: Long-term operation will cause wear, pitting, etc. on the surface of the gear, resulting in the meshing between the gears no longer smoothly, resulting in noise. During severe wear, the tooth shape of the gear will change, further aggravate the noise problem. Poor gear meshing: If there is error in the gear during installation, or if the gear wears, the meshing clearance may be uneven. In addition, the gear has low accuracy level, and the teeth pitch accumulation error and tooth shape error generated during manufacturing will also cause the gear transmission to be unstable, resulting in pulsation and tooth punching, which will cause noise. Gear teeth breaking: When the gears are broken, the broken teeth collide with other gears during operation, which will produce a periodic 'click' sound. Bearing-related problems Bearing damage: When the bearing is worn, the raceway is scarred or the ball is broken, the cage is damaged, when rotating Read More

WPO200-10-B The following precautions are given during the assembly process of worm gear reducer: Preparation and check the parts: Clean the parts of the reducer, and check the status of each part to ensure that there is no damage or missing. In particular, the wear and damage of key components such as worm gears, worm gears, bearings, gears, etc. Confirm fit size: Check whether the fit size of the hole (or shaft) connected to the reducer meets the requirements. The tolerance of the hole should be H7 and the tolerance of the shaft should be H6. Select lubricating oil: Use lubricating oil with high viscosity and extreme pressure performance, such as worm gear and worm special oil. The specifications and dosage of lubricating oil should be determined according to the model and working environment of the reducer. Part installation and installation bearing: Install bearings in the bearing seat on the reducer housing to ensure that the bearing is installed firmly and apply an appropriate amount of grease. Pay attention to the coordination accuracy and installation method during installation to avoid damage to the bearing. Install worm gear: Install worm gear Read More
