The reducer for the trubogib machine is developed ( General machine building )




The drive for the trubogib machine was developed on the basis of a planetary gearbox with a preliminary stage of CJSC Technology Market patent RU2677952. The developed gearbox has a flange mount and two types of output shaft design. This design makes it possible to use this gearbox as an on-board drive of tracked vehicles, winch gearboxes, as well as shut-off valve drives.

Specifications:
1) Gear ratio U = 200;
2) The output torque of M out = 5000 Nm;
3) durability of 7 000 hours;
4) Efficiency of more than 90%;
5) Gearbox weight:
a) Version 1 m = 140 kg;
b) Version 2 m = 124 kg.


This design allows you to implement the gear ratios
U = 150 ... 3500.

Relative comparative characteristics with RP-TM-200-5000:
1.PCR has a larger overall diameter
2.PCR efficiency is less (85%)
3.When the PV operating mode is >50%, the PCR has a drop in characteristics (with continuous operation)

Analog with a three-stage planetary gearbox (weight~700 kg, efficiency <90%)


Relative comparative characteristics with RP-TM-200-5000: 1. The analogue has a large mass (700 kg)

Characteristics:

  • Rated torque: Hm.
