The oil outlet at the shaft end is the first oil outlet, and the oil outlet at the cover end is the second oil outlet. The first oil outlet is oriented opposite to the oil inlet. AA – The direction of the second oil outlet is opposite to that of the oil inlet. AB – The direction of the second oil outlet is rotated 90° counterclockwise relative to that of the oil inlet. AC – The direction of the second oil outlet is the same as that of the oil inlet. AD – The direction of the second oil outlet is rotated 90° clockwise relative to that of the oil inlet. The first oil outlet is rotated 90° counterclockwise relative to the oil inlet direction. BA – Second outlet port oriented opposite to the inlet port BB – Second outlet port rotated 90° counterclockwise relative to the inlet port BC – Second outlet port oriented in the same direction as the inlet port BD – Second outlet port rotated 90° clockwise relative to the inlet port First outlet port oriented in the same direction as the inlet port: CA – Second outlet port oriented opposite to the inlet port CB – Second outlet port rotated 90° counterclockwise relative to the inlet port CC – Second outlet port oriented in the same direction as the inlet port CD – Second outlet port rotated 90° clockwise relative to the inlet port The first oil outlet is rotated 90 degrees clockwise from the oil inlet.° DA – Second oil outlet is opposite in direction to the oil inlet. DB – Second oil outlet is rotated 90° counterclockwise relative to the oil inlet. DC – Second oil outlet is aligned in the same direction as the oil inlet. DD – Second oil outlet is rotated 90° clockwise relative to the oil inlet. |
