Product description
Guomao PV series gear reducerProduct Introduction:
The PV series gear reducer is a universal series gearbox developed by the company in recent years, based on the Flender HB series. (Related link: Difference between PV series and Z series hard tooth reducer)
This series of products covers the original hard tooth surface zdy hard tooth surface gear reducer, ZLY hard tooth surface gear reducer, ZSY, ZFY, DBY, DCY, DFY and other series of products; There are a total of 134 models with a transmission range of 1.25-450. The PV series reducer has a significantly improved load-bearing capacity compared to the hard tooth series (approximately 20% increase in similar center to center distance specifications). And it is suitable for multiple installation methods, which is the development direction of the hard tooth surface series.

Overall comparison of Guomao PV series gear reducers: Type Transmission stage 1 2 Parallel axis P 3 4 2 Vertical axis V 3 4 Transmission ratio range 1.25-5.6 6.3-28 22.4-112 100-450 5-14 12.5-90 80-450 models (specifications) 3-19 4-26 5-26 7-26 4-18 4-26 5-26 Remarks equivalent to ZDY equivalent to ZLY Two stage cylindrical gear reducers equivalent to ZSY equivalent to ZFY equivalent to DBY equivalent to DCY equivalent to DFY Guomao PV series reducers The maximum model 26 # machine (A=860) has a nominal output torque of about 900000 N.m; The nominal output torque of the PV reducer (A=550) for Unit 18 is approximately 250000 N.m. The housing of the PV series gear reducer below Unit 18 is designed for casting, while the above is a welded housing

Sealing method: Install double oil seals on the output shaft; The input shaft of the PV reducer is equipped with a single oil seal at high speed and a double oil seal at low speed. If necessary, labyrinth sealing or other sealing methods can be considered.
Cooling method: The standard design of Guomao PV series reducers includes fan cooling, which can be used when water cooling is not available. The hard tooth surface series has low expandability and is inconvenient for connecting with extended applications such as high speed ratio series connection and vertical installation of reduction motors.

Advantages of Guomao PV series reducers
1. The material of Guomao PV series reducers is better than that of hard tooth surfaces. The PV series gearbox body is cast with resin sand, which has a beautiful appearance.
2. The gear material of PV reducer is better than the hard tooth surface.
3. The bearing model of the PV reducer is larger than the hard tooth surface of the same specification.
4. The weight ratio of precision parts such as gears in PV reducers is larger than that of hard tooth surfaces.
