On the direction of the force of the gear?
The 3. party asked: the axial force of the spiral direction depends on the direction of rotation and tooth gear, according to the "right hand wheel screw rule" to judge. Namely: the driving wheel is right, right according to the direction of rotation shaft, the four refers to the bending direction of said rotary direction driving shaft, with the thumb, the is pointing to the direction of axial force on the driving wheel; the driving wheel is left, it should be left to use the same method to determine the judgment. The driving wheel axial direction, the axial force from the wheel on the size and axial force on the driving wheel is equal and opposite.When the wheel 1 is active, the axial direction of the wheel 1 is left, and the axial force of the wheel 2 is turned to the rightWhen the wheel 2 is active, the axial direction of the wheel 2 is left, and the axial force of the wheel 1 is turned to the right
2. the direction of the radial force: the direction is directed to their respective wheel centerNo matter which is the driving wheel, the radial force direction of the wheel 1 and the wheel 2 point to the respective axes
The forces acting on the helical gear teeth engaged in the engagement can be broken down into circumferential force, radial force and axial force1. the direction of the circumferential force: on the driving wheel, opposite to the direction of rotation, on the driven wheel is the same as that of the steering wheelWhen the wheel 1 is active, the circumferential force direction of the wheel 1 is perpendicular to the surface of the paper, and the circumferential force direction of the wheel 2 is perpendicular to the surface of the paperWhen the wheel 2 is active, the circumferential force direction of the wheel 2 is perpendicular to the surface of the paper, and the circumferential force direction of the wheel 1 is perpendicular to the surface of the paper
