Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an intermittent motion mechanism. Background Art

[0002] In the prior art, when the gear train of a high-voltage switch cabinet needs to achieve different strokes, it often requires multiple gears with different module numbers to cooperate to complete. At the same time, if different strokes need to be achieved in different rotation directions, some additional gears often need to be added, thereby increasing the volume of the gear train. This method increases the load of the equipment and at the same time makes the structure cumbersome and not conducive to maintenance. Therefore, there is an urgent need for an intermittent motion mechanism to solve the above problems. Summary of the Utility Model

[0003] To solve the above problems, the utility model provides an intermittent motion mechanism, which is realized by the following technical solutions.

[0004] An intermittent motion mechanism includes a driving gear, an intermittent gear, a ball bearing chute gear, and a ball bearing transmission gear.

[0006] The intermittent gear is composed of a shaft hole two, a gear side, and an intermittent side provided thereon.

[0007] A chute and a shaft hole three are provided on the ball bearing chute gear, and a ball bearing one is arranged inside the shaft hole three.

[0008] A shaft hole four and a positioning pin are provided on the ball bearing transmission gear, and a ball bearing two is arranged inside the shaft hole four.

[0009] Further, the ball bearing chute gear and the ball bearing transmission gear are coaxial.

[0010] Further, one end of the positioning pin movably penetrates through the chute.

[0011] Further, the driving gear and the intermittent gear are coaxial.

[0012] Further, the driving gear is meshed and connected with the ball bearing transmission gear.

[0013] Further, the intermittent gear is intermittently meshed and connected with the ball bearing chute gear.

[0014] The beneficial effects of the present utility model are as follows: During the operation of the device, through the combination of four different gears, when the driving gear rotates counterclockwise by 360°, the driven gear rotates clockwise by 180°; after the driving gear rotates counterclockwise by 360°, it then rotates clockwise. When the driving gear rotates clockwise by 360°, the driven gear rotates counterclockwise by 180°; when the driving gear rotates clockwise by 360°, the driven gear rotates counterclockwise by 360°; when the driving gear rotates clockwise by 360°, it then rotates counterclockwise. When the driving gear rotates counterclockwise by 360°, the driven gear rotates clockwise by 180°. Through the intermittent motion mode of the combination of four different gears, four different gear strokes can be achieved, providing more design scheme options for the designers of high-voltage switch cabinets when designing operating mechanisms.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] As Figure 1-7 shown, the present invention has the following specific embodiments.

[0030] Embodiment:

[0031] An intermittent motion mechanism includes a driving gear 1, an intermittent gear 2, a ball bearing chute gear 3 and a ball bearing drive gear 4,

[0032] A shaft hole one 101 is provided on the driving gear 1;

[0033] The intermittent gear 2 is composed of a provided shaft hole two 201, a gear side 202 and an intermittent side 203;

[0034] A chute 301 and a shaft hole three 303 are provided on the ball bearing chute gear 3, and a ball bearing one 302 is provided inside the shaft hole three 303;

[0035] A shaft hole four 402 and a positioning pin 401 are provided on the ball bearing drive gear 4, and a ball bearing two 403 is provided inside the shaft hole four 402.

[0036] Specifically, the ball bearing chute gear 3 and the ball bearing drive gear 4 are coaxial;

[0037] One end of the positioning pin 401 movably penetrates through the chute 301;

[0038] The driving gear 1 and the intermittent gear 2 are coaxial;

[0039] The driving gear 1 is meshed and connected with the ball bearing drive gear 4;

[0040] The intermittent gear 2 is intermittently meshed and connected with the ball bearing chute gear 3.

[0041] The working principle of the present invention:

[0042] 1. As Figure 6 shown, when the driving gear 1 rotates counterclockwise, it can drive the ball bearing transmission gear 4 to rotate clockwise. At the same time, the positioning pin 401 on the ball bearing transmission gear 4 moves along the chute 301 on the ball bearing chute gear 3. At this time, the ball bearing chute gear 3 remains stationary and does not rotate;

[0043] When the positioning pin 401 on the ball bearing transmission gear 4 moves along the chute 301 on the ball bearing chute gear 3 to the apex of the stroke, the positioning pin 401 will drive the ball bearing chute gear 3 to rotate clockwise. When it continues to rotate 90°, the gear side 202 of the intermittent gear 2 meshes with the ball bearing chute gear 3. When it continues to rotate to 180°, the intermittent gear 2 and the ball bearing chute gear 3 are disengaged from the meshing state;

[0044] After the intermittent gear 2 and the ball bearing chute gear 3 are disengaged, when the driving gear 1 starts to rotate clockwise, the gear side 202 on the intermittent gear 2 meshes with the ball bearing chute gear 3 and can drive the ball bearing chute gear 3 to rotate counterclockwise. At the same time, the positioning pin 401 on the ball bearing transmission gear 4 passes through the chute 301 and drives the ball bearing chute gear 3 to move synchronously.

[0045] When the intermittent gear 2 rotates 90°, it disengages from the ball bearing chute gear 3. At this time, the positioning pin 401 on the ball bearing transmission gear 4 moves along the chute 301 on the ball bearing chute gear 3. At this time, the ball bearing chute gear 3 does not rotate.

[0046] When the positioning pin 401 on the ball bearing transmission gear 4 moves along the chute 301 on the ball bearing chute gear 3 to the apex of the stroke, the positioning pin 401 will drive the ball bearing chute gear 3 to rotate counterclockwise.

[0047] 2. As Figure 7 shown, when the driving gear 1 rotates clockwise, the positioning pin 401 on the ball bearing transmission gear 4 is at the apex of the stroke and drives the ball bearing chute gear 3 to rotate clockwise through the chute 301. At this time, the intermittent gear 2 meshes with the ball bearing chute gear 3. When the intermittent gear 2 continues to rotate 90°, it disengages from the ball bearing chute gear 3. At this time, the ball bearing chute gear 3 drives the chute 301 to continue to rotate clockwise through the positioning pin 401 on the ball bearing transmission gear 4.

[0048] When the driving gear 1 rotates 360° clockwise and then rotates counterclockwise, the positioning pin 401 on the ball bearing transmission gear 4 moves clockwise along the chute 301 on the ball bearing chute gear 3. At this time, the ball bearing chute gear 3 does not rotate.

[0049] When the driving gear 1 rotates counterclockwise by 180°, the positioning pin 401 on the ball bearing transmission gear 4 moves along the chute 301 on the ball bearing chute gear 3 to the stroke apex, and the positioning pin 401 will drive the ball bearing chute gear 3 to rotate clockwise.

[0050] When the driving gear 1 rotates counterclockwise by 270°, the intermittent gear 2 meshes with the ball bearing chute gear 3.

[0051] When the driving gear 1 rotates counterclockwise by 360°, the intermittent gear 2 disengages from the ball bearing chute gear 3.

[0052] In summary, when the driving gear 1 rotates counterclockwise by 360°, the driven gear rotates clockwise by 180°.

[0053] After the driving gear 1 rotates counterclockwise by 360°, it then rotates clockwise. When the driving gear 1 rotates clockwise by 360°, the driven gear rotates counterclockwise by 180°.

[0054] When the driving gear 1 rotates clockwise by 360°, the driven gear rotates counterclockwise by 360°.

[0055] When the driving gear 1 rotates clockwise by 360°, it then rotates counterclockwise. When the driving gear 1 rotates counterclockwise by 360°, the driven gear rotates clockwise by 180°.

[0056] Through this intermittent motion mode, four different gear strokes are achieved, providing more design option choices for the designers of high-voltage switchgear when designing the operating mechanism.
