CWS100 - 63 - I As a CWS series arc cylindrical worm reducer, relying on the structural advantages of arc tooth meshing, the noise level is in a low range under normal working conditions. The normal operating noise is mostly 60 - 70dB(A). The specifics will fluctuate depending on the working conditions, assembly and maintenance conditions. The following is a detailed description:
Baseline noise range and basis : This model is a medium-sized industrial-grade worm reducer with a center distance of 100mm, a transmission ratio of 63, and the adapted input power and output torque are at a medium level. Combining the common characteristics of worm gear reducers with 'small meshing impact and smooth transmission', as well as the industry's test data for arc tooth worm reducers of the same specifications, under the standard input speed of 1500r/min and rated load conditions, the noise is usually stable at 60 - 70dB (A). This range complies with the conventional noise standards under the rated load of medium-sized industrial reducers, is similar to the noise intensity of daily vacuum cleaner operation, and will not cause serious interference to the workshop environment. In addition, some manufacturers of this series of products indicate that the gears have been processed by gear grinding, which can further improve the transmission balance and bring the noise closer to the lower limit of the range.
Noise fluctuation under different working conditions : The actual noise will change as the working conditions change. For example, during no-load operation, without the meshing pressure caused by load, the noise can be as low as below 60dB (A), which is close to the sound of normal indoor conversation; if it is under high-speed, heavy load or short-term overload conditions, the meshing friction will increase and the noise may temporarily rise to 70 - 75dB (A), but generally it will not exceed 80dB (A). In addition, its transmission ratio reaches 63, which is a larger speed ratio design. The sliding friction noise during low-speed output is lower and can even be controlled within 65dB (A), which is suitable for low-speed transmission scenarios that have certain requirements for silence.
Factors affecting abnormal noise levels : If maintained or assembled improperly, noise can significantly exceed the baseline range. For example, insufficient machining accuracy of the worm and worm gear, and poor meshing due to center distance deviation during installation will produce sharp noises caused by metal friction. Insufficient lubricating oil, inconsistent models, or mixed impurities will aggravate component friction and cause a sudden increase in noise. After long-term use, the bearings are worn and the shell is loosely fixed, causing resonance. Periodic impact sounds or low-frequency roars may also occur. At this time, the noise may exceed 80dB (A), and timely inspection and maintenance are required.
