Whether the rotation direction of the two internal meshing gears is the same

One, if two gears do not mesh with each other, the direction of rotation is uncertain, such as the gear set of any two gears do not mesh the direction of rotation is difficult to determine, may be the same direction, may be the opposite direction, such as the car gearbox can forward, can also be backward, but the direction of the engine is always the same direction.
 
Two, two gear meshing, divided into two situations:
 
1, external engagement, the two gear rotation direction is opposite.
 
2, internal mesh, the two gear rotation direction is the same.
 
Three, two bevel gear, the two gear rotation direction become a certain Angle, are generally 90°, such as the car rear axle gear is changed 90°.
