The output shaft 1 is provided with a moving groove, the axial moving steel ball 11 is arranged on the outer side of the balance block 3 in a rolling manner, and the axial moving steel ball 11 is connected with the inner wall of the moving groove in a rolling manner.
The balance block 3 with all open between middle clutch facing 2 the inclined plane recess, inclined plane jacking steel ball 4 is installed the inclined plane recess, works as the balance block 3 with when middle clutch facing 2 takes place relative rotation, make under the effect of inclined plane recess balance block 3 with middle clutch facing 2 produces relative axial displacement.
The friction surface separating steel balls 5 are located among the balance block 3, the input wheel 7 and the middle friction block 2, when the balance block 3 and the middle friction block 2 rotate relatively and the balance block 3 and the middle friction block 2 move axially relatively, the friction surface separating steel balls 5 push away a contact surface between the middle friction block 2 and the input wheel 7, and at the moment, the middle friction block 2 and the input wheel 7 rotate relatively.
The utility model provides a constant torque force controller's theory of operation as follows:
assuming that the output shaft 1 has a load when the input wheel is used as power input, and the load is relatively large:
the input wheel 7 drives the middle friction block 2 to rotate together through friction force, the middle friction block 2 pushes the balance block 3 to rotate, and the balance block 3 drives the output shaft 1 to rotate;
when the middle friction block 2 drives the balance weight 3 to rotate, a lifting force of an inclined plane is necessarily generated, and as shown in fig. 1, the balance weight 3 moves to the left of the figure;
after the balance block 3 moves to the left, the friction surface separation steel ball 5 can extrude the input wheel 7 and the middle friction block 2, so that the contact surface between the input wheel 7 and the middle friction block 2 is separated;
after separation, relative displacement is generated between the input wheel 7 and the middle friction block 2, once the relative displacement is generated, the balance block 3 can descend immediately, and the friction force can act, so that balance between the friction force and the spring pressure can be achieved.
The spring pressure is F (the slope of the inclined plane cannot be too large, and the friction torque force is larger than the balance torque force if the balance weight does not work, or the friction plane can be made into a conical surface to increase the friction force)
Neglecting rolling friction, torque at equilibrium: and N is F and A, so that a constant torsion effect is achieved. A is a proportionality coefficient, and is related to the inclination of the groove of the middle balance block and the inclination of three inclined planes contacted by the friction surface separation steel ball.
If the balance block 3 and the middle friction block 2 are designed to be single-inclined planes, the constant torque output is unidirectional (namely one direction is spring torque output, and one side is simple friction torque output);
if the balance mass 3 and the middle friction mass 2 are designed as double inclined planes: the output is bidirectional (the positive and negative rotation directions are constant torsion), and the effect of different positive and negative torsion outputs is achieved by changing the different inclination angles of the two surfaces;
the inclined surface of the middle friction block 2 of the balance block 3 can be replaced by a hole to reduce the processing difficulty.
