Abstract
The invention provides a two-way intermittent geneva mechanism which comprises a geneva wheel and cranks, wherein a pin roller and a convex arc are arranged on the cranks; and a geneva wheel groove and a concave arc are arranged on the geneva wheel. The two-way intermittent geneva mechanism is characterized in that the crank include a long crank and a short crank; the geneva wheel groove include an internal geneva wheel groove and an external geneva wheel groove; the distance from a rotating shaft of the geneva wheel to a rotating shaft of the crank is more than the distance from the pin roller on the short crank to the rotating shaft of the crank; and moreover, the distance from the rotating shaft of the geneva wheel to the rotating shaft of the crank is more than the distance from the pin roller on the long crank to the rotating shaft of the crank. The two-way intermittent geneva wheel mechanism provided by the invention can convert continuous rotational movement into two-way intermittent movement.
Description
Technical field
The present invention relates to the intermittent motion mechanism of mechanical field, particularly relate to Geneva mechanism at a kind of two-way intermittence.
Background technique
Existing intermittence, Geneva mechanism was comprised of sheave and crank, was provided with roller and dome arc on the crank, was provided with sheave groove and concave circular arc on the sheave, and in the crank rotation process, when the roller insertion groove race of crank, the roller of crank drives sheave and rotates; When the dome arc of crank entered the concave circular arc of sheave, sheave rotated and stops.Intermittently Geneva mechanism is the intermittent rotary motion with the continuous rotation conversion of motion.
The patent No. is a kind of intermittent type rotation mechanism of 201120368029.7, comprises crank, roller and sheave, and roller is installed on the crank, is provided with four sheave grooves and circular arc on the sheave.A kind of intermittent type rotation mechanism of this model utility, crank constantly rotates, when the sheave groove on the insertion of the roller on the crank sheave, the sheave rotation, when sheave forwards when below to, when the roller of crank was inserted in the circular arc of sheave, sheave stopped the rotation, this gap formula rotating mechanism can carry out clearance type control to rotation, and is easy to adjust.
Although the patent No. is 201120368029.7 intermittent type rotation mechanism is the intermittent rotary motion with the continuous rotation conversion of motion, this intermittent movement in crank sense of rotation one regularly, sheave only has a direction intermittent rotary.
Summary of the invention
The purpose of this invention is to provide Geneva mechanism at a kind of two-way intermittence, this, Geneva mechanism can be two-way intermittent movement with the continuous rotation conversion of motion at two-way intermittence.
In order to achieve the above object, two-way intermittence of the present invention Geneva mechanism, comprise sheave and crank, be provided with roller and dome arc on the crank, be provided with sheave groove and concave circular arc on the sheave, it is characterized in that: crank has two kinds on long crank, short crank, the sheave groove has two kinds of inside groove race, water jacket races, distance between sheave running shaft and the crank running shaft greater than roller on the short crank to the distance between the crank running shaft, and, the distance between sheave running shaft and the crank running shaft greater than roller on the long crank to the distance between the crank running shaft.
Because crank of the present invention has two kinds on long crank, short crank, the sheave groove has two kinds of inside groove race, water jacket races, distance between sheave running shaft and the crank running shaft greater than roller on the short crank to the distance between the crank running shaft, and, distance between sheave running shaft and the crank running shaft greater than roller on the long crank to the distance between the crank running shaft, when crank rotates, after the roller on the long crank inserts the inside groove race, drive sheave and rotate towards a direction; Driving sheave after the roller on the short crank inserts the water jacket race rotates in the opposite direction; When the roller of long crank, short crank not in outer groove-wheel groove, inside groove race, and the dome arc is when entering concave circular arc, sheave stops operating, two-way intermittence of the present invention, Geneva mechanism can be two-way intermittent movement with the continuous rotation conversion of motion.
Two-way intermittence of the present invention, Geneva mechanism can be two-way intermittent movement with the continuous rotation conversion of motion.

Embodiment
The explanation of Fig. 1 mark: sheave 1, inside groove race 2, concave circular arc 3, sheave running shaft 4, water jacket race 5, short crank 6, dome arc 7, crank running shaft 8, long crank 9, roller 10.
Referring to Fig. 1, the embodiment of the present invention's Geneva mechanism at two-way intermittence is comprised of sheave 1 and crank, be provided with roller 10 and dome arc 7 on the crank, be provided with sheave groove and concave circular arc 3 on the sheave 1, crank has 6 two kinds on long crank 9, short crank, the sheave groove has 5 two kinds of inside groove race 2, water jacket races, the distance that distance between sheave running shaft 4 and the crank running shaft 8 arrives between the crank running shaft 8 greater than roller on the short crank 6 10, and, the distance that the distance between sheave running shaft 4 and the crank running shaft 8 arrives between the crank running shaft 8 greater than roller on the long crank 9 10.
Among the embodiment, crank has 6 two kinds on long crank 9, short crank, the sheave groove has 5 two kinds of inside groove race 2, water jacket races, the distance that distance between sheave running shaft 4 and the crank running shaft 8 arrives between the crank running shaft 8 greater than roller on the short crank 6 10, and, the distance that distance between sheave running shaft 4 and the crank running shaft 8 arrives between the crank running shaft 8 greater than roller on the long crank 9 10, when crank rotated, drive sheave 1 rotated (referring to Fig. 2 and Fig. 3) towards a direction after the roller 10 on the long crank 9 inserts inside groove race 2; Drive sheave 1 rotates (referring to Fig. 5 and Fig. 6) in the opposite direction after the roller 10 on the short crank 6 inserts water jacket race 5; When the roller 10 of long crank 9, short crank 6 not in outer groove-wheel groove 5, inside groove race 2, and dome arc 7 is when entering concave circular arc 3, sheave 1 stops operating (referring to Fig. 4), and two-way intermittence of the present invention, Geneva mechanism can be two-way intermittent movement with the continuous rotation conversion of motion.
Two-way intermittence of the present invention, Geneva mechanism can be two-way intermittent movement with the continuous rotation conversion of motion, and applying of it has positive effect to the structure of simplifying two-way intermittent movement, reliability and the precision that improves motion.
