Abstract
The utility model relates to the technical field of a mechanical transmission device and particularly provides an elastic worm wheel. The elastic worm wheel comprises a wheel body and a wheel shaft, wherein the wheel shaft is inserted into a shaft hole at the circle center of the wheel body; a sliding groove is arranged on the wheel body; and a convex tooth is arranged on the wheel shaft. The sliding groove is arranged on the wheel body; the convex tooth is arranged on the wheel shaft; and the convex tooth is nested into the sliding groove and fastened by a spring. In the use process, a gap between the worm wheel and the worm rod is removed under an effect of the spring, so as to greatly improve the transmission precision. Furthermore, the elastic worm wheel has the advantages of simple structure, low manufacture cost and good effect.
Description
Technical field
The utility model relates to the mechanical transmission technical field, especially a kind of elastic force worm gear.
Background technique
At present; The worm and gear transmission is one of type of belt drive the most widely in the mechanical transmission; Because its transmission accuracy depends on the machining accuracy of worm gear, the worm gear that precision is not high should not use in high-precision transmission, and high-precision worm gear processed complex; Fabricating cost is high, thereby makes the use of this kind of drive in precision drive be restricted.Thereby cause the frictional force between worm gear and the worm screw big, wearing and tearing are big, the problem that heat is big.
The model utility content
Low in order to overcome existing worm gear precision, the deficiency that cost is high, the utility model provides a kind of elastic force worm gear.
The utility model solves the technological scheme that its technical problem adopted: a kind of elastic force worm gear, comprise wheel body and wheel shaft, and wheel shaft is inserted in the axis hole in the wheel body center of circle, and wheel body is provided with chute, and wheel shaft is provided with double wedge.
According to another embodiment of the utility model, comprise that further chute is evenly distributed on the end face of wheel body, around the axis hole of the center of circle.
According to another embodiment of the utility model, comprise that further double wedge is evenly distributed on the circumferential surface of wheel shaft, embed in the chute of wheel body.
According to another embodiment of the utility model, comprise that further the quantity of double wedge is consistent with the quantity of chute, each chute is embedded in a double wedge.
According to another embodiment of the utility model, further comprise between double wedge and the chute being provided with spring.
According to another embodiment of the utility model, comprise that further an end of spring withstands on the front portion of chute, the other end withstands on the double wedge.
The beneficial effect of the utility model is, chute is set on wheel body, and double wedge is set on the wheel shaft, and double wedge is embedded chute; And give through spring fastening, in the using process, under the effect of spring; Gap between worm gear and the worm screw is eliminated, thereby improve its transmission accuracy greatly, and; Simple in structure, processing cost is low, and is respond well.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. wheel bodys among the figure, 2. wheel shaft, 3, chute, 4. double wedge, 5. spring.
Embodiment
Like Fig. 1 is the structural representation of the utility model, and a kind of elastic force worm gear comprises wheel body 1 and wheel shaft 2, and wheel shaft 2 is inserted in the axis hole in wheel body 1 center of circle, and wheel body 1 is provided with chute 3, and wheel shaft 2 is provided with double wedge 4.Chute 3 is evenly distributed on the end face of wheel body 1, around the axis hole of the center of circle.Double wedge 4 is evenly distributed on the circumferential surface of wheel shaft 2, embeds in the chute 3 of wheel body 1.The quantity of double wedge 4 is consistent with the quantity of chute 3, and each chute 3 is embedded in a double wedge 4.Be provided with spring 5 between double wedge 4 and the chute 3.One end of spring 5 withstands on the front portion of chute 3, and the other end withstands on the double wedge 4.
Chute 3 is set on wheel body 1, double wedge 4 is set on the wheel shaft 2, double wedge 4 is embedded chute 3; And give through spring 5 fastening, in the using process, under the effect of spring 5; Gap between worm gear and the worm screw is eliminated, thereby improve its transmission accuracy greatly, and; Simple in structure, processing cost is low, and is respond well.
