The structural auxiliary measures of the CWS200-12.5-SZ worm gear reducer mainly include improving transmission accuracy, improving lubrication conditions, enhancing heat dissipation performance and ensuring sealing reliability, etc., aiming to improve the operating stability and service life of the equipment under complex working conditions.
1. Optimize tooth design and improve meshing performance
The CWS series adopts Niemann-type cylindrical worm transmission, and its core structural advantage is reflected in the precise matching of tooth profile shapes.
Arc tooth surface grinding processing : The worm is ground to significantly improve the tooth surface finish and geometric accuracy, and reduce the sliding friction coefficient during the meshing process.
Concave-concave tooth profile meshing mechanism : The worm has a convex surface and the worm gear has a concave surface, resulting in a larger contact area and more even stress distribution, effectively improving the load-bearing capacity and reducing local wear.
Increase the circumferential speed angle : This design is conducive to the formation of a stable hydrodynamic oil film, improves the lubrication state, and slows down fatigue failure of the tooth surface.
2. Strengthen the lubrication system to ensure continuous oil film formation
Good lubrication is the key to reliable operation of worm gear reducers, and CWS200-12.5-SZ supports efficient lubrication through structural design.
Oil bath lubrication adapter structure : The box design ensures that the worm gear is partially immersed in lubricating oil to achieve self-supply lubrication, suitable for medium and low speed working conditions.
Reserved forced lubrication interface : For high load or continuous operation scenarios, an oil pump circulation system can be installed to spray cooled clean oil directly into the meshing area to improve heat dissipation and anti-wear effects.
Convenient design for oil level and oil drain : It is equipped with a clear oil mark, a high-level ventilation hole and a low-level oil drain plug to facilitate daily maintenance and oil replacement.
3. Enhance heat dissipation capacity and control temperature rise
Due to the relatively low efficiency of worm gear transmission, a large amount of energy is converted into heat energy, which requires structural means to assist heat dissipation.
Heat dissipation ribs are provided on the outer surface of the box : increase the contact area with air, improve natural convection heat dissipation efficiency, and prevent lubrication failure caused by excessive oil temperature.
Expandable air-cooling or water-cooling device : Some models have reserved installation positions and support external fans or oil coolers. They are suitable for high-temperature environments or heavy-load continuous operation conditions.
4. Improve sealing protection level to resist external pollution
In order to adapt to harsh environments such as dust and moisture at industrial sites, the reducer adopts multiple sealing measures in key parts.
Double-layer sealing structure at the shaft end : It adopts a combination of skeleton oil seal and labyrinth seal to effectively prevent dust intrusion and lubricating oil leakage.
Respirator design : When the pressure inside the box changes, the air pressure can be balanced by a filter respirator while blocking moisture and particulate matter from entering.
CWS200-12.5-SZ supports multiple installation methods to meet different equipment layout needs.
Multi -directional output configuration (SZ type features) : SZ represents double shaft extension or special installation form, which is convenient for connecting couplings, brakes or other transmission components.
Standardized base and flange interface : easy to connect directly to the motor or fixed to the frame, making installation and debugging more convenient.
