Abstract
The utility model discloses a transmission gear structure of a low noise mini-type stepping motor, which comprises a pair of round gear disks and tooth parts arranged on the edges of the gear disks, wherein the gears are made of a PA (Poly A) material; the number of the big gears in the tooth parts is 40; the number of the small gears is 8. According to the technical scheme, the transmission gear structure of the low noise mini-type stepping motor, provided by the utility model improves the rigidity and the toughness of the gears, effectively reduces the engaging-in and the engaging-out impact when the gears are meshed, and reduces the vibration and the low noise of the noise.
Description
Technical field
The utility model relates to the driving gear field of micro-step motor, relate in particular to a kind of can effectively reduce gear when engagement engaging-in, nibble out impact, reduce to vibrate the driving gear structure with the low-noise micro-size stepper motor of noise.
Background technique
Traditional micro-step motor mostly adopts the plastic cement gear to carry out transmission, resiliently deformable can occur in the plastic cement gear under the effect of engaging force, after gear shifting quadrant texturing, two engaging gears change at the basic point of line of contact position, and are no longer equal, thereby cause the collision in gear when engagement and scraping when nibbling out followed, noise control is undesirable, therefore, is necessary engaging gear is carried out rational profile of tooth correction and optimization, in the time of can effectively reducing to mesh engaging-in, nibble out impact, reduce the vibration and noise.
Therefore, need badly a kind of can effectively reduce gear when engagement engaging-in, nibble out impact, reduce to vibrate the driving gear with the low-noise micro-size stepper motor of noise.
The model utility content
The purpose of this utility model be to provide for the deficiencies in the prior art a kind of can effectively reduce the gear engagement time engaging-in, nibble out impact, reduce to vibrate the driving gear structure with the low-noise micro-size stepper motor of noise.
To achieve these goals, the utility model provides following technological scheme: a kind of driving gear structure of low-noise micro-size stepper motor, the gear disk that comprises a pair of circle, described gear disk edge is provided with uniform tooth section structure, the number of teeth of described canine tooth wheel disc tooth section is 40, and the number of teeth of small gear dish tooth section is 8.
The angle of the pressure angle of described tooth section is set to 20 degree.
The modification coefficient of described tooth section is 0.4.
The canine tooth tooth of described tooth section is long is 0.9025mm.
The material of described gear is polyamide (PA) material.
Compared with prior art, the utility model provide a kind of can effectively reduce to mesh the time engaging-in, nibble out impact, reduce to vibrate the driving gear with the low-noise micro-size stepper motor of noise.Significance for gear on noise is set modulus and is 0.25, the canine tooth number of teeth is 40 during design, the little tooth number of teeth is 8, and pressure angle is set as 20 degree, 0.05 millimeter of sideshake, modification coefficient 0.4, canine tooth tooth long 0.9025.Can bump in the impact process of miniature stepper motor; in order to reduce to collide the noise that sends; the material of common meeting usage comparison softness; as TPE etc.; but, use soft material easily to cause in process of production the tooth wound, for rigidity and the toughness that guarantees that gear is certain; adopt rigidity PA material preferably, and the toughness when having designed long toothing increasing the gear engagement on canine tooth.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Description of drawings
Fig. 1 is an embodiment's the structural representation of the driving gear of the utility model low-noise micro-size stepper motor.
Embodiment
In order better to understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail, in accompanying drawing, similar element numbers represents similar element.
As shown in Figure 1, the utility model embodiment provides a kind of driving gear structure of low-noise micro-size stepper motor, the gear disk that comprises a pair of circle, have the gearwheel of comprising 1 and small gear 2, described gear disk edge is provided with uniform tooth section structure 3, the number of teeth of described canine tooth wheel disc tooth section is 40, and the number of teeth of small gear dish tooth section is 8.
The angle of the pressure angle of described tooth section is set to 20 degree.
The modification coefficient of described tooth section is 0.4.
The canine tooth tooth of described tooth section is long is 0.9025mm.
The material of described gear is polyamide (PA) material.
The utility model adopts technique scheme, provide a kind of can effectively reduce to mesh the time engaging-in, nibble out impact, reduce to vibrate the driving gear with the low-noise micro-size stepper motor of noise, adopt the PA material, and use long toothing on canine tooth, improved rigidity and the toughness of gear, further by the design parameter of Optimal Setting gear, integral body has effectively reduced the noise that sends in gear operation collision process.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
