Hydraulic transmission GOP-900 is used as a component of hydro-mechanical gear boxes of heavy tracked vehicles with weight of up to 60 t to provide stepless control of speed when driving and turning the vehicle.
The hydraulic transmission is a monoblock that includes two radial-piston hydraulic machines (variable capacity pump and hydraulic motor) and hydraulic equipment to provide protection from overload and functioning in closed fluid circulation system.
|output power||up to 350 kW|
|rotatinal speed||up to 3100 rpm|
|pressure||up to 32 MPa|
|torque||up to 2800 N.m|
|efficiency||up to 80%|
|fluid temperature||up to 130°С|
|weight (without gear box driving shafts)||260 kg|
When developing hydraulic transmission GOP-900, the following scientific and technical tasks were solved:
Engineering and design solutions implemented in our hydraulic radial ball transmissions provided high wear resistance of piston groups and distributor unit, which was confirmed by durability tests.
Hydraulic ball piston transmissions and hydraulic machines based on them (pumps and hydraulic motors) are one of prospective trends in development of hydraulic drive due to simple design, superior performance and minimum axial dimensions.
Hydraulic transmission GOP-900 developed in the CIS has no analogs in the world in terms of capacity and max speed. Experience gained during development and production activities makes it possible to extend the nomenclature of hydraulic transmissions with respect to their capacity, to develop split hydraulic transmissions for transport and stationary machines as well as unique pumps capable to deliver up to 2000 l/min and high-speed high-torque hydro-motors.
