WS300-23.5-II The transmission efficiency of the worm gear reducer is affected by a variety of factors, as follows: Worm lead angle: The larger the lead angle, the smaller the sliding friction between the worm and the worm gear tooth surface, and the higher the transmission efficiency. Generally speaking, the lead angle is Between 3.5°-33°, if it exceeds 30°. Although the efficiency will be further improved in theory, the processing difficulty will increase significantly. In addition, the lead angle of the multi-head worm is larger than that of the single-head worm, so under the same conditions, the transmission efficiency of the multi-head worm (such as double-head and triple-head) is higher, but the transmission ratio will be reduced accordingly. Material pairing and friction coefficient: Usually the worm is made of steel, such as medium carbon steel or medium carbon alloy steel, while the worm gear is made of bronze, such as cast tin bronze or cast aluminum bronze. This combination of steel worm and bronze worm gear can effectively reduce the coefficient of friction, reduce wear, and thus improve transmission efficiency. In addition, the worm is inserted into Read More

There are many reasons why the WB100-D-23-0.55KW micro cycloid reducer may fail. The following are some common factors: 1. Lubrication problem Inadequate lubrication: Insufficient lubricating oil will increase friction between parts and parts, which will not be well protected and heat dissipated, thereby accelerating wear and causing failures, such as gear wear, bearing damage, etc. Poor oil quality: The lubricant used is of poor quality, or the lubricant has not been replaced for a long time, and contains impurities, moisture, etc., which will reduce the lubricating effect, increase the wear of parts, and may also cause lubricating system to be blocked. Lubricant oil Selection error: If the selected lubricant does not meet the requirements of the reducer, such as inappropriate viscosity, and cannot form a good lubricant film on the surface of the parts, it will also affect the normal operation of the reducer. 2. Overload operation: When the load borne by the reducer exceeds its rated load, internal gears, bearings and other components will bear excessive pressure. Read More

There are usually some common standards for the grease replacement cycle and method of micro cycloid reducers, but please refer to the product manual for details. The following is the relevant content about grease replacement for WB1285-LD-2065-0.37KW/4 micro cycloid reducer: Replacement cycle General situation: According to the common cycloid reducer usage specifications, the newly purchased reducer should undergo the first grease replacement after initial operation of 300-600 hours. After that, under normal use conditions, that is, working for no more than 10 hours a day and the ambient temperature and other conditions are more suitable, it is recommended to replace the grease every 6-12 months. Special circumstances: If the reducer runs more than every day 10 hours, or the working environment temperature is higher (more than 40℃), lower (less than - 15℃), and in harsh environments such as high dust and high humidity, the replacement cycle of grease should be shortened.

The main disadvantages of arc gears in high-speed transmission: 1. It is difficult to process and has a higher cost. The tooth profile accuracy of arc gears has a great impact on high-speed performance, but its processing technology is much more complicated than involute gears: Special equipment depends on: special arc gear milling cutters and grinders (such as Y3180 arc gear milling machine), and processing equipment cannot be used for involute gears, and the equipment investment cost increases by 50% to 100%. Strict accuracy control: The arc tooth profile 'tooth arc radius''tooth drum volume' of the arc tooth profile needs to be strictly matched (small deviation at high speed will cause a sudden increase in contact stress), the processing tolerance needs to be controlled at IT5~IT6 levels (the high-speed stage of involute gears is usually IT6~IT7 levels), the machining working hours increase by 30%~60%, and the final gear manufacturing cost is 40%~80% higher than that of involute gears. 2. Installation requirements are extremely high for neutrality and poor fault tolerance. The installation deviation of gears in high-speed transmission ( Read More

The installation method of the output shaft of the cycloid pin wheel reducer of different models may have the following differences: installation method and alignment requirements for horizontal installation: such as XWD/BWD series horizontal cycloid pin wheel reducer, the output shaft is parallel to the ground, and it must be installed on a horizontal basis without vibration and solidity during installation. The inclination of the axis line shall not be greater than ±15°. During installation, it is necessary to ensure that the output shaft is consistent with the axis of the driven mechanical equipment. It is usually necessary to connect with a coupling, which requires high centering requirements, otherwise it may lead to reduced transmission efficiency or equipment damage. Vertical installation: Some models are flange vertical cycloid pin wheel reducer, with the output shaft vertically downward and can be installed horizontally, but if the output shaft needs to be installed upward, special instructions are required when ordering. This installation method requires high sealing of lubricating oil to avoid leakage. Special installation: Some reducer models with torque arms, such as FA47/T, output shaft through torque arms with drive and load Read More

Special precautions for different types of cycloid pin wheel reducers need to be adjusted in a targeted manner according to the differences in installation methods and structural characteristics to avoid adaptation problems caused by 'general operation': 1. The fuel tank of the horizontal cycloid pin wheel reducer (most common, such as X and B series) is 'side-mounted', and the oil level is greatly affected by the installation level. The core attention is 'horizontal degree and oil level': Installation level check: Before refueling, you need to use a level to detect the level of the fuselage (required ≤0.1mm/m). If the fuselage is inclined (such as one side is high and the other side is low), it will cause the oil level in the fuel tank to 'one side is high and one side is low'. The base gasket must be adjusted first to ensure level before refueling; oil outlet anti-blocking: The oil outlet of the horizontal model (connected to the lubricating oil pump) is located at the bottom of the oil tank. If impurities are mixed during refueling, it is easy to block the oil outlet, causing the lubricating system to break oil- It is recommended to run for 5 minutes after refueling and observe the bearing seat temperature ( Read More
