The spare parts for Auger drive

The most popular model REA7000 which used for 7-10T excavator such as SY70, PC70, JCB-3CX, JCB-4CX, CAT307 and so on. The motor of REA-7000 use Eaton China 4K. Eaton China, Eaton USA or any other counties, Eaton has a strict and standard production process. 

1.As below are the driving torque we test.  

Bar	Driving torque(REA7000)
50	650
70	1080
90	1437
110	2053
130	2353
150	2875
170	3167
190	3540
210	3913
240	4344

2.Except the motor, the important is gear box. Gear is the heart of gear box. The material, the hardness and the treatment is the key. These are all controlled by ourselves. For the total parts we produce by ourselves. Each parts we have parts no. This is easy for us to follow up each parts. Who produce it, when it finished, the gear or bearing used for which model auger drive.

3.Hood ear：The main difference is the shape not the thickness. Our shape have bigger welding area about more than types. So it will be stronger than the Delta shape. About the thickness, if we add the angel it’s 37mm total. The steel plate is 18mm, the thinnest for the side is 15mm. As below are the pictures.

4.Output shaft: an edge on the both sides of the hole screw fixing pin, the edge. The shaft without an edge has a considerably more large maximum 

stress area, that’s why it increases the total stress on the machine through the shaft under the driving torque applying while drilling. Red round indicates the area of maximum stress. There clearly seen that 

the edge reduces the area of high stress.
