Description
Technical Field
The utility model belongs to the technical field of mechanical transmission, and particularly relates to an intermittent rotary gear mechanism.
Background
The existing rotary intermittent output motion mechanism is provided with a grooved wheel, incomplete teeth, a ratchet wheel and the like. The design parameters of the incomplete teeth are complex, the appearance of the parts is processed by a special machine tool, and the abrasion of the shafts and the discs in the grooved pulley mechanism affects the precision. The swing pin stepping motion mechanism has low motion positioning precision and low motion rigidity. The stepping mechanism is powered by a stepping motor, electronic equipment such as a frequency converter is needed, the control mode is complex, each step may be unstable under heavy load in the stepping process, and the stepping of each step is imprecise and needs to be controlled through feedback.
At present, the intermittent transmission of equipment generally adopts motor drive, and the action is accomplished through intermittent mechanism, and motor drive takes up a relatively large space, and intermediate transmission mechanism is more, causes whole equipment structure complicated, installation required space big.
The prior patent CN201621243193.4 is an intermittent transmission device, adopts the driving of an air cylinder, greatly simplifies the tedious structure of the traditional intermittent transmission equipment, greatly saves the installation space, and simultaneously utilizes the transmission mechanism to complete the ratchet wheel positioning by design; however, the transmission and reset mechanisms are still complex, and the time treatment for intermittent transmission is not accurate enough.
Disclosure of Invention
The present utility model is directed to solving the above-mentioned problems in the background art, and for this purpose, provides an intermittent rotary gear mechanism.
The technical scheme adopted for solving the technical problems is as follows:
an intermittent rotary gear mechanism comprising a mechanism link; the driving gear and the driven gear are fixed on the gear rotating shaft, and the driving gear and the driven gear are meshed with each other; the gear surface of the driving gear is divided into a fixed part and a movable part.
Preferably, the movable part is movably sleeved on the gear rotating shaft, and a distance is arranged between the movable part and the fixed part.
Preferably, the device further comprises a limiting spring, wherein two ends of the limiting spring are respectively fixed on the surfaces of the fixed part and the movable part.
Preferably, the driving gear is connected with the motor.
Compared with the prior art, the utility model has the beneficial effects that:
1. according to the utility model, the driving gear and the driven gear are adopted for transmission, and the movable part arranged on the driving gear can effectively realize indirect transmission between the two gears;
2. through setting up the drive motor in the driving gear rear side, accessible motor rotational speed adjusts gear rotational speed, cooperates the connection between spring and the two gears simultaneously, reaches the effect of intermittent type transmission.
Drawings
The utility model will be further described with reference to the drawings and examples.
FIG. 1 is a front elevational view of the structure of the present utility model;
FIG. 2 is a rear elevational view of the structure of the present utility model;
FIG. 3 is a side view of the structure of the present utility model;
the embodiment of the utility model mainly comprises the following element symbols:
the mechanism comprises a mechanism connecting rod-1, a driving gear-2, a driven gear-3, a gear rotating shaft-4, a fixed part-5, a movable part-6 and a limiting spring-7.
Detailed Description
In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
As shown in fig. 1 to 3, an intermittent rotary gear mechanism includes a mechanism link 1; the device further comprises a driving gear 2 and a driven gear 3, wherein the driving gear 2 and the driven gear 3 are fixed on a gear rotating shaft 4, and the driving gear 2 and the driven gear 3 are meshed with each other; the gear surface of the driving gear 2 is divided into a fixed part 5 and a movable part 6. The driving gear 2 is connected with a motor.
The movable part 6 is movably sleeved on the gear rotating shaft 4 and is provided with a distance from the fixed part 5. Since the fixed portion 5 is fixed to the gear shaft 4 and the movable portion 6 is not fixed to the gear shaft 4, the movable portion 6 should not rotate with the gear shaft 4 when the fixed portion 5 rotates.
The device also comprises a limit spring 7, wherein two ends of the limit spring 7 are respectively fixed on the surfaces of the fixed part 5 and the movable part 6, so that the fixed part 5 and the movable part 6 are pulled and spliced together by the limit spring 7. Therefore, when the movable part 6 is matched with the driven gear 3, the movable part 6 and the driven gear 3 are in a static state, the limiting spring 7 is lengthened along with the movable part, the driven gear 3 is restored to be engaged with the fixed part 5 after the interval rotation is finished, and the movable part 6 is rebounded to the original position under the traction of the limiting spring 7.
With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
