Differential shell blanks in china manufacturers tell you that the double worm differential is a newly invented product. Differential shell blanks in china manufacturers tell you that its feature is that two intermeshing worms are installed in the rotor obliquely, and the two worm shaft ends are respectively connected with the output shafts on both sides. The available gear connection or universal joint connection, the ring gear is installed on the rotor. The whole is fixed to the casing by bearings, the power source is input by the ring gear, and the output shafts on both sides output power.

Differential shell blanks in china manufacturers tell you that the two worms use a small lead angle, and the size of the lead angle determines the degree of self-locking. In the worm and turbine transmission, the worm is active, the turbine is driven, and the two worms are meshed, which is equivalent to each other's turbines. When the lead angle is small enough, the two worms will be interlocked. It only turns when torque is applied on both sides, so that's what makes it self-locking without affecting differential driving.
If used in the center differential, the pitch circle diameters of the two worms can be adjusted to output different torques front and rear. The advantages are small size, simple processing, low cost, and a comprehensive solution to full-time four-wheel drive.
The above information is the Differential shell blank in china manufacturer's introduction and analysis of the double worm differential, hope it helps you.
