Claims

[Scope of utility model registration request]

A sun gear 21 attached to the main driving shaft 8 of the main motor 2, a first planetary gear 24 that meshes with the sun gear 21 and revolves around the main driving shaft 8, and a first planetary gear 24 that supports the first planetary gear 24 and around the main driving shaft 8. A rotary support body 22 that rotates at The attached passive gear 27 and the first reduction mechanism 5 are composed of a worm wheel 28 formed on the outer periphery of the rotation support 22, a worm gear 29 that meshes with the worm wheel 28, and a child of the worm gear 29 and the child electric motor 3. A second speed reduction mechanism 6 is configured with a power transmission mechanism 30 that interlocks and connects the side driving shaft 18, and the output shaft 4 can be selectively rotated at high speed or low speed by selectively driving the parent motor 2 and the slave motor 3. In the variable speed drive device, the parent motor 2 and the slave motor 3 each have a separate casing 7,
17, each driving shaft 8, 18 protrudes outside from the respective casing 7, 17, and each reduction mechanism 5, 6 is provided outside the casing 7, 17, furthermore, the child side driving shaft 18 is A variable speed drive device characterized in that the worm gear 29 and the axis are arranged so as to be parallel to each other.
