The Worm Gear Reducer Is a Power Used to Convey

The worm gear reducer is a power used to convey, by using the gear speed converters, the worm gearbox can decelerate the number of the rotary motor to the desired rotational speed, and reach to a institutions of the larger torque. At present, the reducer has a wde range of application between the power transmission and movement institutions. The worm gearbox can be seen in almost all kinds of mechanical drive system from the transport ships, automobiles, motorcycles, construction heavy machinery, processing machinery and automated production equipment used in the machinery industry, daily life home appliances, watches and so on. applications from large power transmission, to a small load, the precise angle transmission can be seen to slow down the application of machine, and in industrial applications, the reducer to slow down and increase the torque function. Therefore, it is widely used in the speed and torque conversion equipment. The role of the reducer: 1, spin-down and increasing the output torque, the torque output ratio multiplied by the motor output gear ratio, but need to be careful not to exceed the rated torque of the reducer. 2, slow down and reduce the load inertia Frequently asked questions and analysis of worm reducer 1, reducer fever and oil spills In order to improve efficiency of Worm gear speed reducer, the gearboxes are generally non-ferrous metals to do the worm, take the hard steel to do the worm gear, because it is the sliding friction drive and will produce a higher heat during operation, the parts of the reducer and sealing between the thermal expansion to vary at all with the surface gap, fluid temperature thinning, likely to cause leakage. There are four main reasons, First, the material with reasonable, the second is the surface quality of meshing friction surface and the third is the choice of lubricants, add the correct amount of assembly quality and use environment. 2, the wear and tear of worm gear Commonly used tin bronze worm gear, worm material is generally paired with 45 steel hardened to HRC45 a 55, also commonly used in 40C: hardened HRC50 a 55, the worm grinder grinding to a roughness RaO 8 fcm the normal operation of the reducer. "rasp" of the worm is like a hardened, kept cutting and filing the worm gear, worm produce wear. Generally speaking, the wear is very slow, some deceleration can be like a factory for more than 10 years. If you wear faster, it is necessary to consider the selection of the reducer is correct, if overload operation, the material of the worm, assembly, quality or use of the environment and other reasons. 3, the wear and tear of drive small helical gear The situation is generally happened in the deceleration on the vertical installation, it mainly be connected with the amount of lubricating oil and lubricants choice. When take the Vertical installation, it is easily lead to a lack of lubricating oil. Once stop operation of the reducer, motor and gear reducers will loss the transmission gear oil, so that the gear can not get proper lubrication protection, and the start or operation of the process can not be effectively lubrication even leading to mechanical wear or damage. 4, the worm bearing damage Once the reducer goes wrong, even if the deceleration box sealed, the plant is often found reducer gear oil has been emulsified, bearings rust, corrosion, damage, that is because of the speed reducer shipped stop the process, gear oil generated after the thermal cooling water condensation caused; of course, it is also closely related to the bearing and the method of the assembly process.
