Model WPW40-250 worm gear reducer produced by Shanghai Nuoguang manufacturer

Shanghai Nuoguang Manufacturer specializes in the production and manufacture of worm gear reducers with high quality, beautiful prices, complete models and specifications, and quality assurance.
The structural materials of the worm gear reducer case are all cast iron. The common structural materials for the output end cover of the worm gear reducer are cast iron and aluminum alloy. The hardness and temperature resistance of cast iron are higher than that of aluminum alloy. Be stronger. Both have advantages and disadvantages. The advantages of cast iron end caps are temperature resistance and high strength. The disadvantage is that they are bulky and have a rough surface that does not dissipate heat as well as aluminum alloy. The advantages of aluminum alloy end caps are light weight, smooth and beautiful surface, and relatively high heat dissipation. The disadvantage is that it will melt and deform after being exposed to high temperatures for a long time. Once deformed, the sealing performance of the oil seal will decrease, eventually leading to oil leakage in the reducer. . The worm gear reducer is a kind of transmission equipment. During the working process, the surface temperature and internal temperature will also increase over time. High temperatures can cause the aluminum alloy end cover to melt, eventually causing the output end cover of the worm gear reducer to deform and deform after melting at high temperature. Oil leakage. In addition, cast iron end caps can also play a certain role when it is necessary to support the weight of objects.
The characteristics of the series worm gear reducer are as follows:
, smooth transmission, small vibration, impact and noise, large reduction ratio, wide versatility, and can be used with various mechanical equipment.
, can obtain a larger transmission ratio with single-stage transmission, and has a compact structure. Most types of reducers have good self-locking properties and can save braking devices for mechanical equipment with braking requirements.
The meshing friction loss between the worm thread and the worm gear tooth surface is large, so the transmission efficiency is lower than that of the gear, it is prone to heat generation and the temperature is higher.
, the requirements for lubrication and cooling are higher.
Worm gears and worms with good interoperability are manufactured according to national standards. Bearings, oil seals, etc. all use standard parts.
There are basic types of cabinets (the cabinet is a vertical or horizontal structure with foot plates) and a universal type (the cabinet is a rectangular parallelepiped with fixed screw holes on multiple sides without foot plates or separately installed). The input shaft connection methods include basic type (single input shaft and double input shaft) and motor flange.
The position direction of the output and input shafts is that the input shaft is at the bottom and the output shaft is up and down, and the input shaft is up and down.
One or more reducers can be used to form a multi-stage reducer to obtain a huge transmission ratio.
The worm is made of #high-quality steel and processed by heat treatment. The worm gear is made of tin bronze and has good wear resistance, especially in terms of load-bearing capacity.
The sealing of the joint surface of the upper and lower shells of the worm gear reducer is the main sealing point of the reducer. Insufficient smoothness of the joint surface, deformation of the upper and lower cover steel plates due to thinness, and insufficient strength of the bolts can also cause lubricating oil to leak out. As the use time of the reducer continues to accumulate, it is easy to cause multiple faults such as the aging of the reducer oil seal and the wear of the shaft head, which can also cause the leakage of lubricating oil from the input and output shafts of the reducer. In addition, the aging of the skeleton sealing ring will also cause oil leakage from the reducer head.
