Abstract

The invention relates to a reciprocating linear movement and rotational movement converter for a small-semicircular gear. The reciprocating linear movement and rotational movement converter comprises a rack rail. The rack rail is connected with a piston and comprises an ascending rack and a descending rack which are parallel to each other; the small-semicircular gear is connected into the rack rail in a meshed manner, and a transition gear with local gear teeth is coaxially connected with the small-semicircular gear; a substitute rack gear which is locally provided with gear teeth and can be connected with the transition gear in a meshed manner is correlated and connected with the rack rail. The reciprocating linear movement and rotational movement converter has the advantages that a connecting rod and the piston are reliably connected with each other in a gear and rack meshed mode, the reciprocating linear movement and rotational movement converter has a stable stroke and is high in thrust and free of dead points, outputted power can be maximized, and energy generated by an internal combustion engine can be sufficiently utilized.

Example Embodiment

[0019] In the drawings, the small semicircular gear reciprocating linear motion and rotary motion converter includes a rack rail 1 connected with a piston 5, and the rack rail 1 consists of two parallel upward rack 1-1 and downward rack. 1-2 composition; the rack rail 1 is internally meshed and connected with a small semicircular gear 2, and the small semicircular gear 2 is coaxially connected with a transition gear 3 with partial gear teeth; the rack rail 1 is associated with one A rack-and-pinion gear 4 that is partially provided with gear teeth and can mesh with the transition gear 3.

[0020] The arc length of the small semicircular gear 2 is less than 1/2 of the circumference of the tooth tip; the sum of the arc length of the transition gear 3 with gear teeth and the arc length of the small semicircular gear 2 is equal to the small semicircular gear 2 tooth tip 1/2 of the circumference.

[0021] The radius of the addendum circle of the small semicircular gear 2 is equal to the radius of the addendum circle of the transition gear 3 and the radius of the addendum circle of the rack gear 4.

[0022] 1/2 of the circumference of the tooth tip of the small semicircular gear 2 is equal to the length of the rack rail 1.

[0023] 1/2 of the circumference of the tooth tip of the rack and pinion 4 is equal to the length of the rack rail.

[0024] The size and shape of the transition gear 3 and the alternate rack gear 4 are the same.

[0025] The rack-and-pinion gear 4 always rotates at the same speed as the small semicircular gear 2 in the opposite direction.

[0026] The working principle of the present invention is: in the initial state, one end of the small semicircular gear 2 is meshed and connected with the upward rack 1-1 of the rack rail 1. At this time, the transition gear 3 and the substitute rack gear 4 are in a separated state; Push the rack rail 1, and the small semicircular gear 2 rotates counterclockwise. When the small semicircular gear 2 is completely separated from the rack rail 1, the transition gear 3 and the alternate rack gear 4 mesh; continue to rotate the small semicircular gear 2 until the rack orbit The one-way stroke of 1 is completed, at this time the small semicircular gear 2 rotates half a circle, the small semicircular gear 2 meshes and connects with the downward rack 1-2, and separates from the upward rack 1-1. At this time, the transition gear 3 and the substitute rack The gear 4 separates again; when the rack rail 1 is pushed in the opposite direction, because the small semicircular gear 2 meshes with the downward rack 1-2, it still rotates counterclockwise. In this way, the reciprocating work of the piston 5 can be realized.

[0027] The provision of the transition gear 3 and the rack-and-pinion gear 4, and the association between the rack-and-pinion wheel 4 and the rack rail 1 can ensure that the small semicircular gear 2 is completely separated from the rack rail 1 relative to the rack rail 1. The offset occurs to facilitate the smooth meshing of the two next time and prevent the misalignment of the teeth; the setting of the small semicircular gear 2 can ensure that the gear and rack lock will not occur during the working process of the present invention occur.
