Problems solved by technology

The universal joint power transmission component adopts split assembly, and the power transmission pin 106 cooperates with the power receiving part 105 and the ball 103 through the shaft hole. When the power transmission component 10 swings along its axis, the power transmission pin also occurs. If there is a gap, the power transmission pin cannot be fixed on the power receiving part 105 and the ball 103, causing the power transmission pin to fall off easily, which will affect the power transmission
Therefore, the disadvantage of this universal joint is that its manufacturing precision is higher, and the manufacturing cost is higher.
If the universal joint does not adopt a split type but is integrally formed, in order to prevent the ball from falling off, the ball stopper 1041 needs to be larger than the outer diameter of the ball, so the ball needs to be firmly pressed into the gear of the photosensitive element during assembly. The method will make the sphere limit part easy to deform, and the deformed sphere will easily fall off, and the material elasticity requirements for the sphere limit part are high, and the manufacturing cost is high
The baffle 102 is installed inside the gear 104 close to the end of the sphere to limit the axial movement of the sphere 103. Since the baffle is fastened on the gear through an interference fit, the impact force on the universal joint will make the sphere The gap h between the baffle and the baffle increases, resulting in an increase in the axial movement of the universal joint, which will reduce the stability of power transmission
