The worm gear reducer is a power that is used to convey, using the converters gears, the worm gearbox transmission delay the number of the rotary engine to the desired speed, and to achieve a higher torque of the institutions. At present, the gearbox has a WDE variety of purposes, between the Power Transmission and movement settings. |
The worm gearbox is seen in almost all types of mechanical drive system of transport ships, cars, motorcycles, heavy machinery construction machinery and equipment for the automatic production machine industry, household appliances everyday life, watches and such. applications of large power transmission, a small load, the transmission exact angle can be seen to delay the application of the machine, and in industrial applications, reducer to slow down and increase the torque function. Therefore it is widely used in both speed as linking conversion equipment. Hangzhou China Base (speedreducer.org) is the leading supplier of worm gear.
The role of the transmission :
1. spin-off and increase the output torque, the ratio of the output torque multiplied by the gear ratio of the engine, but be careful not to exceed the nominal torque of the gearbox.
2. Delay and reduce the inertia of the load
Worm reducer classification Main models: WP series Worm Gerboxes, WH series worm and CW series worm Gearbox.
1.WP series worm Gearbox, including WPA / WPS / the WPW /, WPE / WPZ / WPD 2.WH series worm Gearbox, including the WHT / WHX / WHS / WHC 3.CW series worm Gearbox, including the CWU / CWS / the CWO 4.RV series worm Gearbox RV / NMRV / NRV
Questions and analysis of worm reducer frequent
1. Fever reducible oil disaster
The effectiveness of the worm gear improve reducers are generally non-ferrous metals to do the worm, take the steel difficult to do the worm gear, as it the unit sliding friction and produce a higher heat during use,overbrengingsonderdelen and seal between the thermal expansion of the opening exchange surface, the temperature of the fluid thinner, through which leakage can occur. There are four important reasons, in the first place the material with reasonable, the second is the quality of the surface meshing friction and the third is the choice of lubricants, add the correct amount of assembly and quality of the user interface.
2. The wear of the worm
General tin bronze worm gear, worm material usually associated with 45 hardened steel HRC45 to 55, also used in 40C: tempered HRC50 to 55, the worm mill to a roughness RAO 8 FCM normal operation of the reducer. "Grate" of the worm as a tough, stop and filing the worms, worm produces wear. In general, the wear and tear very slow, which could delay a factory more than 10 years. If you wear faster, you should consider when selecting the transmission is correct, if overload operation, the material of the worm, assembly, quality or use of the environment and for other reasons.
3. The wear and tear of drive small helical gear
The situation usually happens delay on the vertical installation is primarily related to the amount of lubricating oil and lubricants choice. If your vertical installation, it easily leads to a lack of oil. Once you have the service of the gearbox, engine and reducers loss transmission gearbox oil to stop, so the acceleration adequate protection lubrication can not get, and the beginning of the process or the operation may be an effective lubrication even bring to mechanical wear or damage .
4. The worm bearing damage
Once the gearbox goes wrong, if the sealed delay, it is often reduced oil emulsified bearings rust, corrosion, damage, sent by the speed stop the process, oil rates generated cooling water for thermal condensation caused, of course, is also now connected to the lower and the method of assembly.
