Abstract

PURPOSE:To reduce the number of the parts in the title transmission by arranging conical input and output gears in such a way as having the reverse shape each other therein and meshing a junction gear to the middle part thereof. CONSTITUTION:There is arranged a conical input gear 2 and a conical output gear 4 in such a way that the conical shape is set to be reversed and the facing surface is made in parallel to each other. A junction gear 3 is meshed with the middle part thereof. Since a motor is connected to an input shaft 9 and a conveyer is connected to an output shaft, the conveyer is increased in speed with the junction gear located on the lower part. As a speed change adjusting bar 5 is moved in the direction of the arrow B, the conveyer is decreased in speed. Thus, it is possible to reduce the number of the parts in the transmission resulting in the simplified structure.

When a motor is connected to the input shaft of , and a conveyor is connected to the output shaft of 10, the relay gear 3 is located at the bottom, so the gear ratio between the input gear 2 and the output gear 4 is larger on the input side, and the output is larger. Since the sides are small, the speed of the conveyor is faster. If you want to lower the speed of the conveyor, move the relay gear 3 in the direction of arrow B using the speed adjustment rod 5.
The gear ratio between input gear 0 and output gear 4 is smaller on the input side and larger on the output side, so the output shaft 10 rotates at a low speed and the conveyor speed is low. It is operated by a servo motor and can be easily controlled automatically.

又、３の中継歯車は当然ながら入力軸に回転がなければ
移動させてはならないものである。Also, the relay gear 3 must not be moved unless the input shaft rotates.
