Because the shaft-mounted non-standard reducer is not supported by the base, it completely relies on the direct connection between the output shaft and the load shaft (or motor shaft) to achieve positioning. At high-speed operation (usually ≥3000rpm), slight shaft system deviation will be amplified into vibration and impact, which will directly affect the equipment life and operation stability. To ensure installation accuracy, it is necessary to implement precise control throughout the entire process around the four core dimensions of axis system centering, connection rigidity, reference constraints, and error compensation. The specific methods are as follows: 1. Core premise: Accurately control the coaxiality of the shaft system (high-speed precision 'lifeline'). The accuracy of shaft-mounted installation is essentially the neutrality of the 'axis-axis'. The radial offset at high speed must be ≤0.01mm and the angular offset ≤0.03°. It must be realized through professional tools and processes: 1. Use the principle of 'reference priority' to determine the positioning reference first with the load shaft (such as the working machine spindle and motor shaft) as the reference shaft, and the reducer output shaft is actively adapted and aligned.

Determine the rated load based on the model of the soft tooth surface reducer. A comprehensive judgment is required based on the model coding rules, manufacturer's technical parameters and actual working conditions. The specific methods are as follows: 1. Analyze the load information in the model coding ‌ Model structure disassembly‌ Soft tooth surface reducer models such as series code, center distance, speed ratio (such as R series, K series), where the center distance (such as R37, K67) is directly related to the rated torque. For example: ‌R series‌: The center distance of 37mm corresponds to the rated torque of about 50N·m, and 67mm corresponds to 200N·m. ‌K Series‌: The digital part of the model (such as K67) indicates the center distance. For every 10mm increase, the rated torque is increased by about 30%-40%. At the same center distance between speed ratio and torque, the larger the speed ratio, the higher the rated torque. For example, the K67-50 model (speed ratio 50:1) is higher than the K67-20 model (speed ratio 20:1) rated torque Read More

The service life of the WPDX120-30-3KW worm gear reducer is usually around 5-10 years. The service life of the worm gear reducer is affected by a variety of factors, such as load size, load type, lubrication condition, installation accuracy and working environment. If the reducer works under rated load, has good lubrication, meets the requirements, and has a suitable working environment, its service life may be close to or reaches 10 years. On the contrary, if it is in an overload state for a long time, or the working environment is harsh, such as high temperature, humidity, corrosive gases, etc., it may shorten the service life of the reducer to 5 years or even shorter. Key measures to extend the service life of WPDX120-30-3KW worm gear reducer 1. Installation and operation environment optimization Basic installation requirements ensure that the flatness error of the reducer installation surface is ≤1.5mm/m, and the anchor bolts are subject to the torque specified by the manufacturer (such as M16 bolt 200 Read More

The transmission efficiency of the WPDX135-40-3KW worm gear reducer (usually in the range of 65%~80%) is affected by a combination of various factors. The core is based on the characteristics of worm gear and worm transmission 'sliding friction dominates and multi-components work together'. It can be mainly classified into four categories: core characteristics of the meshing sub-core characteristics, lubrication system status, structural design and manufacturing accuracy, and operating conditions. The specific analysis is as follows: 1. Characteristics of the worm gear and worm gear meshing pair (the most critical influencing factor, accounting for more than 60%) The worm gear and worm transmission is based on 'sliding friction as the main and rolling friction as the auxiliary'. The design, material and coordination accuracy of the meshing pair directly determine the basic transmission efficiency. 1. Number of worm heads and transmission ratio of worm heads: are the core variables that affect efficiency. The more worm heads (number of threads), the larger the lead angle, and the lower the proportion of 'sliding friction components' during meshing, the higher the efficiency. This model has a transmission ratio of 40 (large transmission ratio). Read More

BLEY5527-289-15KW Oil leakage at the sealing of the cycloid pin wheel reducer can be quickly solved by the following methods: Use sealant or leak plugging agent: If it is a slight oil leakage, apply an appropriate amount of high-temperature resistant sealant to the sealing surface or bolt connection to enhance the sealing effect. Special lubricant leak plugging agent can also be added. This additive can form a temporary sealing film at the oil leakage point, which plays an emergency leak plugging role. Adjust the oil level: Check the oil level of the reducer. If the oil level is too high, excess lubricating oil must be released through the oil drain hole to keep the oil level at the center line of the oil standard to reduce oil leakage caused by excessive oil level. Clean the vent holes: Blockage of the vent holes will increase the pressure inside the reducer, causing oil to seep out of the seal. Therefore, the ventilation holes should be cleaned in time to ensure that they are unobstructed, so that the internal pressure of the reducer is balanced with the external pressure. Tightening bolts: Check whether the bolts at the seal are loose. If they are loose, they need to be twisted evenly in multiple diagonal orders. Read More

The sealing device of the output shaft of the cycloid pin wheel reducer mainly prevents lubricating oil leakage through the following methods: Oil seal seal: Usually a skeleton oil seal is used, and its cross-sectional shape is J-shaped. It uses the elasticity of the lip-shaped structural part and the clamping force of the coil spring coil to make the lip-shaped part close to the shaft surface. The sealing ring is equipped with a metal frame, which achieves axial fixation by the cooperation of the periphery and the hole. If it is mainly for oil sealing, the sealing lip should face the bearing, thereby preventing the lubricant from leaking out of the gap between the output shaft and the end cap. Oil return tank design: A oil return tank tilted into the machine in the center of the lower tile of the bearing seat, and a notch is also made at the straight opening of the end cover, which faces the oil return tank. In this way, the excess lubricant that is thrown by the gear on the bearing will flow back to the oil tank in a certain direction through the notch and the oil return tank to avoid the accumulation of lubricant at the shaft seal, thereby reducing the possibility of leakage. Sealant auxiliary: on the end cover and box of the reducer Read More
