When replacing the output shaft of the BWD22 - 29 - 4KW cycloidal pinwheel reducer, you need to follow the core process of 'disassembly - cleaning and inspection - assembly - trial operation'. During the operation, the components must be marked to avoid assembly misalignment and protect precision components from damage. The specific steps are as follows: 1. Preparation before replacement 1. Safety and on-site preparation: Disconnect the power supply of the reducer first and hang a warning sign to prevent misstarting. Clean the working area and lay down protective mats to prevent parts from being bumped or contaminated with impurities; wear anti-cut gloves and goggles to ensure safe operations. 2. Preparation of tools and materials: Prepare hex wrenches, torque wrenches, three-claw pullers, copper rods, markers, cleaning cloths and other tools; prepare a new output shaft of the same model, as well as supporting seals, fastening rings, grease, sealant and other consumables, and prepare kerosene or gasoline for cleaning parts. 2. Disassemble the old output shaft 1. Drain and mark the oil: unscrew the oil drain screw Read More

There is no absolute superiority or inferiority between cycloidal pinwheel reducer and worm gear reducer. There are significant differences between the two in terms of transmission efficiency, self-locking performance, applicable scenarios, etc., and they need to be combined with specific working conditions Selection. The following comparative analysis from the core performance, applicable scenarios and other dimensions will help you clearly judge the type of adaptation needs: 1. Core performance comparison transmission efficiency: the single-stage efficiency of the cycloidal pinwheel reducer reaches 90%-95%. The transmission process is mainly based on rolling friction, and power loss Low consumption, suitable for long-term continuous operation; the efficiency of worm gear reducer is only 40%-90%, due to sliding friction during meshing, serious heating, and the larger the speed ratio, the lower the efficiency, the energy consumption is higher under high-power conditions. Transmission ratio: cycloidal pinwheel reducer transmission ratio single-stage transmission ratio 11 - 87, the two-stage transmission can reach 121 - 5133, the speed ratio range is wide and the efficiency can be maintained high; the single-stage transmission ratio is 10 - 100+, although the speed ratio is also large, the high efficiency range is narrow Read More

SCWS250 - 51 belongs to the SCWS series of shaft-mounted arc cylindrical worm reducers with a transmission ratio of 51 and a center distance of 250mm. There is no clear calibration value for the noise change when the load changes. However, based on the structural characteristics of this series of reducers, the rules of similar equipment in the industry and general standards, the following range and corresponding characteristics can be sorted out: During no-load operation from no-load to rated load, there is no output torque load, and the noise is mainly the slight meshing sound of the worm gear and the running sound of the bearing. The noise at this stage is usually around 60 - 65dB(A), similar to normal indoor conversation. As the load gradually increases to the rated load, the meshing surface pressure increases gently, and the noise will slowly rise. When the rated load is reached, the noise is generally stable at 70 - 80dB(A). At this stage, the noise changes slowly, with an overall fluctuation range of about 10 - 15dB(A), and the noise is mainly smooth low-frequency roar, without any sharpness. Read More

CCWS250 - 200 - 1 belongs to CCWS Series worm gear reducers, there is no fixed standard for the noise change range when the load changes. The core is affected by its own component factors such as meshing transmission accuracy, lubrication status, bearings and assembly conditions, as well as external factors such as installation and operating environment. The details are as follows: 1. Factors related to meshing transmission Parts processing accuracy: If the worm gear of the reducer has a pitch error, high tooth surface roughness, or deviations in lead and helix angle, the tooth surface contact will be more uneven when the load changes. For example, when the load increases, the pressure on the meshing surface that originally lacked accuracy will increase sharply. Not only will the noise increase significantly, but sharp whistling may also occur. For example, the worm helix angle error will cause periodic abnormal noise in the meshing area. The larger the load, the more obvious the abnormal noise will be, and the range of noise changes will also expand. Parts wear degree: After long-term use, if the worm gear tooth surface appears pitting, wear, or even partial peeling Read More

XLEDC8245B - 841 - 5.5KW belongs to the X series cycloid reducer. The 5.5KW power is suitable for the power needs of common equipment such as spinning machines, looms, printing and dyeing machines in textile machinery, 841 The large transmission ratio meets the low-speed and heavy-load transmission requirements of textile machinery, and has significant advantages in use in textile scenarios, as follows: 1. Strong transmission adaptability, ensuring production accuracy (1) Large transmission ratio adaptation process requirements: The transmission ratio of this model of reducer reaches 841, while textile machinery such as winders, sizing machines, etc. need to operate at low speeds and stably to ensure even yarn winding and smooth slurry application. It can achieve a high reduction ratio without the need for multi-stage complex transmission, reduce precision loss in the transmission link, and avoid problems such as uneven yarn tightness and skewed fabric textures. (2) High efficiency reduces energy consumption costs: the first-level reduction efficiency of the cycloidal pinwheel reducer can reach 94%. The 5.5KW model Read More

XWEDV4/4 - 8160C - 104 The output shaft shoulder of the cycloidal pinwheel reducer is a key part of stress concentration. If cracks here are not dealt with in time, the damage will gradually spread from the shaft itself to the entire machine and related equipment, and even cause safety accidents. The details are as follows: Power transmission failure, interrupting the production process: The output shaft is the core component of the reducer to transmit power to the load end of textile machinery, conveying equipment, etc. Shoulder cracks will reduce the torque carrying capacity of the shaft. With the action of alternating loads during the operation of the equipment, the cracks will continue to expand and may eventually cause the output shaft to break. At this time, the reducer cannot The corresponding power of 5.5KW is effectively transmitted to downstream equipment, directly causing the production line to shut down. For continuous production scenarios, this downtime will bring significant production efficiency losses and economic losses. Exacerbating the wear of the entire machine components and causing cascading failures: cracks in the shaft shoulder will destroy the coaxiality of the output shaft operation, causing Read More
