ARA series spiral bevel gearboxes adopt scientific design scheme and are indispensable products for transmission equipment industry.ARA series gearboxes have excellent performance, light weight, small volume and large load; the shell is sturdy and made of high quality aluminum alloy die-casting; beautiful appearance, reasonable design, positive and negative operation, multi-directional structure for input and output mode, and various output modes. Wide range of application, high torque, low noise and long life.

Product model: AAA1 ARA2 ARA4 Transmission ratio: 1:1, 2:1

I. Product features

1. Highly modular design: can be easily matched with various types of motors or other power inputs. The same model can be equipped with a variety of power motors. Easy to complete the combination of connection between models.

2. Transmission ratio: fine division, wide range. Combined models can constitute a large transmission ratio, that is, the output speed is very low.

3. Installation mode: installation orientation is not restricted.

4. High strength and small volume: The box body is made of high strength cast iron. Gears and gear shafts use gas carburizing quenching and fine grinding technology, so the bearing capacity per unit volume is high.

5. Long service life: In the correct selection (including the use of appropriate coefficients) and the normal use of maintenance conditions, the reducer (in addition to wearing parts) the life of the primary parts of the general not less than 20000 hours. Wearable parts include smooth oil, oil seals and bearings.

6. Low noise: the primary parts of the reducer are precision processed and assembled and tested, so the noise of the reducer is low.

7. High efficiency: The efficiency of single model is not less than 95%.

8. Can withstand large radial load.

9. Can withstand axial load of not more than 15% of the radial force.
