Excavators gearbox
Product Description
Propel reducer and swing reducer are planetary transmission reducers which have features like modularization, compact structure, heavy load, steady & high efficiency transmission, etc. Hoist reducer is a double-gear drive parallel axes reducer, which has the structure of 2-input-1-output style, and has features like high speed ratio and large transmission capacity.
Feature
1. High strength casting iron with low vibration.
2. It has good rigidity , resistance to impact ,transmitting large torque and run-stop frequently.
3. The gearbox features compact structure, light weight, small volume, high ability of load ,low noise and vibration
4. The gearbox can achieve test of temperature and vibration automatically.
5. The gear is manufactured by high-quality alloy steel with carburizing and quenching. The tooth surface hardness is HRC57+4.The gear is modified with serrated form .The class of precision is 5～6.The material of cutting edge: 4Cr5WMoVSi
6. The gearbox adopts mechanical sealing, which has good effect. It’s sealing structure is reliable and non-maintaining .
7. The gearbox uses forced spray oil lubrication, the lubrication pipelines is distributed in or out of the gearbox, which can lubricate the gear and bearing sufficiently. The oil inlet and the oil discharge mouth are mounted on the gearbox .The pressure switch, the flux monitor and the cut-off valve are mounted near the oil inlet. The pressure switch and the flux monitor can monitor the oil supply and feed back the pressure and flux signal which is switch quantity or analog quantity to primary control system.
These gearboxes has been widely used in excavators around world including Australia, USA, Brazil, South Africa and etc.
