The attribute division of the observation area (observation window) and the operation area (oil filling port and oil discharge port) optimizes the maintenance experience and improves the maintenance efficiency.

The appearance of the box body is integrated with elements of speed and strength, and ribs with different density are reasonably arranged on the side to improve the heat dissipation effect of the product and reduce dust accumulation.

The rounded tail is closed to improve the negative pressure turbulence formed by the air outside the gearbox during high-speed operation. The added tail guard plate prevents the influence of flying stones on the product.
