る。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides a mechanism for transmitting rotational torque and position using gears, in which a gear made of an elastic material is used in parallel with an ordinary gear having rigidity. This invention relates to a speed reduction mechanism using gears that eliminates punctures in the transmission mechanism.

合が多(使用上問題となっている。Conventionally, the method of eliminating banocranosis in gears is to use two identical gears and push one side with a spring, as shown in Figure 1, or, in the case of a bevel gear, to push it with spring tension, as shown in Figure 2. I was going. These methods complicate the structure of the mechanism;
This method is difficult to adopt in devices such as robots where the reduction mechanism needs to be lightweight and simple.
Items like the one shown in the diagram often do not fit into the regular interlocking teeth (this poses a problem in use).

The object of the present invention is to provide a speed reduction mechanism using gears that can be applied to various types of two-vehicle transmission mechanisms and eliminates puncture.

なくさせる役割を負わせたことを特徴とする。The present invention combines two gears with the same tooth shape made of two different materials, one made of a normal flying material and the other made of an elastic and wear-resistant material. By using them as a single gear, one performs the role of transmitting rotational torque and position as a normal gear, and the other has a spring action that constantly deforms the tooth profile during meshing in order to maintain bakutaku. It is characterized by having the role of eliminating looseness.
本発明の実施例を第6図を用いて説明する。 An embodiment of the present invention will be described using FIG. 6.

お回転位置精度は歯車11.12によっである範囲に制
限していることになる。First, assume that there is a normal pair of gears (11, 12). The gears are made of commonly used materials such as 845C and have a regular tooth profile. This gear 11.12
It is assumed that the tooth thickness and center distance are set to certain values. A single gear 16 is provided.The gear 13 is the gear 1.
(For 1), the cranancy is 7'l (the teeth are always slightly deformed so that they touch each other.7) Moreover, gears 11 and 12 are rigid bodies, so they cannot normally transmit rotational torque and rotational position to each other. Yes, gear 16 is gear + 1
In the meshing of '12, gear 11 always meshes with gear 11 before gear 12 by the thicker tooth thickness, and because they always rotate in close contact, there is no interaction between the gears, there is no sudden change in the transmitted torque, and smooth transmission is possible. It is. Note that the rotational position accuracy is limited to a certain range by the gears 11 and 12.

得られる。The method of the present invention can be applied to various tooth profiles as shown in Figures 4a-D. Even in the case of a bevel gear, which conventionally had to be made as shown in FIG. 2, by providing the shaded portion with an elastic material by the above method, a method of eliminating backlash can be obtained.

4)歯あたりがまず弾性を持った歯にあたるので歯車の
騒音を低減できる。4) Since the teeth first come into contact with elastic teeth, gear noise can be reduced.
