П.В. серии вообще редукторный окно

1.Highly standard modular designed, more sizes with a reduced variety of parts. 2.Higher operational reliability combined with increases power capacity. 3.Mounting position: The gear units can be supplied for either horizontal or vertical installation.Other arrangements are also possible on request. 4.Long service life: Under the condition of accueately selecting type size and the normal maintenance and use,main components(expect those easily-disabled parts) can last as long as up to more than 50,000 hours. 5.Low noise: All key components are finished by precisely maching;grinding the gears;designing noise-absorbing housings;accurate assembly,and finally tested,and therefore,fairly low noise is reached. 6.Thermal conduction: PV series gear units a favourable thermal conduction,because: 1.The gear units have a high efficiency. 2.Through enlarged housing surface areas. 3.Because large fans incorporating a new type of air conduction fan cowl are being used...
