Description

1. brief introduction :

IWYHG high speed hydraulic slewing drives series are designed for excavators. It consists of valve block with brake function, hydraulic motor, brake, multi-stage planetary gearbox. It features high working pressure, good stability, compact design, light weight, easy installation and maintenance. It can bear hydraulic and external load impact. The output gear shaft can directly drive the ring gear on the slewing platform. With above advantages, these products are widely used in slewing platform drives in construction vehicles, crawler excavators, aerial platforms, tracked vehicles and so on. They are not only popular in Chinese market, but also exported to Singapore, India, Korea, Netherlands and other countries in the world.

The models listed in this catalogue are already put into production. We can also produce different products according to different installation dimension and reduction ratio requested by customers. Please contact our technical department or sales department for more information if need.

2、Model selection:

3、Example of model no:

IWYHG 33A -2800 means the slewing drive has two-stage planetary gearboxes, module of first stage gearbox is 3mm, module of second stage gearbox is 3mm, the design mark is A, and the nominal output torque is 2800N.m.

4. Definition

1) Total displacement(ml/r) is the amount of oil needed for one rotation of hydraulic transmission drive.

Total displacement (ml/r) =displacement of hydraulic motor (ml/r) * reduction ratio

2) Theoretical oil flow of the pump (1/min)= total displacement (ml/r) * output shaft speed of hydraulic transmission drive (r/min) / 1000
