Abstract

The utility model discloses a transmission gear with a chamfer angle and belongs to the technical field of transmission components. The transmission gear with the chamfer angle comprises a gear body and gear teeth, an inner gear ring is arranged at the center of the gear body, a tooth slot is formed between each two adjacent gear teeth, one end of each of the gear teeth and the tooth slots is processed with an oblique chamfered face, the tooth top surface of each gear tooth is a plane, and the cross of the oblique chamfered face and the plane is processed into the chamfer angle. The transmission gear with the chamfer angle enables the impact force to the gear to be greatly reduced when changing a gear, is easy to change the gear, and enable the service life of the gear to be prolonged.

Description

A kind of gearbox gear with chamfering
Technical field
The utility model relates to a kind of gear, more particularly, relates to a kind of gearbox gear with chamfering.
Background technique
Gearbox is can fix or stepping changes the gear drive of output shaft and input shaft velocity ratio, it is comprised of driving mechanism and gear, generally comprises input shaft, output shaft, jack shaft and is set in gear on input shaft, jack shaft and output shaft etc.Two-axis or the triple axle of the general employing of gearbox, can be divided into five gear formulas, six gear formulas etc. according to the slewing range of gearbox, is all provided with a plurality of engaging gears on these gearboxes, and the rotating speed of the gear in different gears and the moment of torsion bearing are also different.Gearbox acts on huge for cotton picker, briefly, has the different gear pair of many group velocity ratios in gearbox, and the gear shift behavior of cotton picker while travelling namely works gear pairs different in gearbox by operating mechanism.As when the low speed, allow the large gear pair work of velocity ratio, and when high speed, allow the little gear pair work of velocity ratio.Gearbox transmission efficiency in above-mentioned cotton picker is high, be quick on the draw, but due to synchronizer not being installed, in switching gear process, can there is " synchronously " problem, gearbox input shaft and output shaft rotate with speed separately, and two different gears of rotational speed mesh by force impact will inevitably occur, and affect the working life of gear.
Summary of the invention
1. the technical problem that model utility will solve
The purpose of this utility model is to overcome gearbox gear of the prior art and when gearshift, impacts excessive, affect the deficiency in working life, a kind of gearbox gear with chamfering is provided, adopt the technical solution of the utility model, at one end of the gear teeth and teeth groove processing ramp down edged surface, and adopting chamfering to seamlessly transit at ramp down edged surface and the crossing position of gear teeth Topland, the suffered impact dynamics of gear while greatly having reduced conversion gear, extends working life of gear.
2. technological scheme
For achieving the above object, the technological scheme that the utility model provides is:
A kind of gearbox gear with chamfering of the present utility model, comprise gear body and the gear teeth, described gear body center is provided with ring gear, between described adjacent two gear teeth, be provided with teeth groove, the described gear teeth and one end of teeth groove are processed with ramp down edged surface, the Topland of the described gear teeth is plane, and the intersection of ramp down edged surface and plane is provided with chamfering.
Further, described chamfering is circular arc chamfering, and above-mentioned circular arc chamfering and ramp down edged surface tangent.
Further, the described gear teeth have several, are evenly distributed in gear body.
Further, described teeth groove is the arc teeth groove tangent with the gear teeth.
3. beneficial effect
The technological scheme that adopts the utility model to provide, compares with existing known technology, has following beneficial effect:
(1) a kind of gearbox gear with chamfering of the present utility model, between its adjacent two gear teeth, be provided with teeth groove, and processing ramp down edged surface in one end of the gear teeth and teeth groove, the suffered impact of gear while having slowed down to a certain extent conversion gear, makes gearshift easily;
(2) a kind of gearbox gear with chamfering of the present utility model, the Topland of its gear teeth is plane, the intersection of ramp down edged surface and plane is processed to chamfering, the suffered impact dynamics of gear when this chamfering has further reduced conversion gear, and in the time of preventing gear engagement, there is " collapsing tooth " situation in the gear teeth, extends the working life of gear;
(3) a kind of gearbox gear with chamfering of the present utility model, its teeth groove is the arc teeth groove tangent with the gear teeth, is convenient to processing, has increased the engagement degree between gear;
(4) a kind of gearbox gear with chamfering of the present utility model, simple in structure, easy to operate, reasonable in design, good stability, and bearing capacity is strong.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation with the gearbox gear of chamfering of the present utility model.
Label declaration in schematic diagram: 1, gear body; 2, the gear teeth; 3, ramp down edged surface; 4, ring gear; 5, chamfering.
Embodiment
For further understanding content of the present utility model, by reference to the accompanying drawings the utility model is described in detail.
In conjunction with Fig. 1, a kind of gearbox gear with chamfering of the present utility model, comprise gear body 1 and the gear teeth 2, gear body 1 center is provided with ring gear 4, between adjacent two gear teeth 2, be provided with teeth groove, one end of the gear teeth 2 and teeth groove is processed with ramp down edged surface 3, and the Topland of the gear teeth 2 is plane, and ramp down edged surface 3 is provided with chamfering 5 with the intersection of plane.
Below in conjunction with embodiment, the utility model will be further described.
Embodiment
As shown in Figure 1, a kind of gearbox gear with chamfering of the present embodiment, comprises gear body 1 and the gear teeth 2, and the gear teeth 2 have several, are evenly distributed in gear body 1.Gear body 1 center is provided with ring gear 4, between adjacent two gear teeth 2, is provided with teeth groove, and the teeth groove of the present embodiment is the arc teeth groove tangent with the gear teeth 2, has both been convenient to processing, can increase again the engagement degree between phase gear main body 1.One end of the gear teeth 2 and teeth groove is processed with ramp down edged surface 3, and the suffered impact of gear body 1 while having slowed down to a certain extent conversion gear, makes gearshift easily.The Topland of the gear teeth 2 is plane, ramp down edged surface 3 is provided with chamfering 5 transition with the intersection of above-mentioned plane, the chamfering 5 of the present embodiment is circular arc chamfering, this circular arc chamfering and ramp down edged surface 3 are tangent, when conversion gear, have further reduced the suffered impact dynamics of gear body 1, make gear body 1 more easily enter working position, in the time of can also preventing gear body 1 engagement, there is " collapsing tooth " situation in the gear teeth 2, extends the working life of gear body 1.
A kind of gearbox gear with chamfering of the present utility model, simple in structure, easy to operate, reasonable in design, gearshift is easy, good stability, bearing capacity is strong.
Below schematically the utility model and mode of execution thereof are described, this description does not have restricted, and shown in accompanying drawing is also one of mode of execution of the present utility model, and actual structure is not limited to this.So, if those of ordinary skill in the art is enlightened by it, in the situation that not departing from the utility model creation aim, without the creationary mode of structure similar to this technological scheme and the embodiment of designing, all should belong to protection domain of the present utility model.
