Abstract
The utility model belongs to the technical field of cultivators, and particularly relates to a self-lubricating driving gear. The self-lubricating driving gear resolves the technical problems of insufficient reasonability, short service life and the like in the prior art. The self-lubricating driving gear comprises a gear body provided with a plurality of teeth distributed uniformly, wherein a center hole is formed in the center of the gear body. The self-lubricating driving gear is characterized in that two end faces of each tooth are respectively provided with a chamfer, a plane is arranged at the top of each tooth, the inner wall of the center hole is provided with at least one spiral oil storage groove, and the thickness of the gear body is identical to that of each tooth. Compared with the prior art, the self-lubricating driving gear has the advantages that design is more reasonable, the service life is prolonged imperceptibly, and the friction coefficient is reduced particularly; the self-lubricating driving gear can achieve self-lubrication, therefore, use cost is reduced, and the self-lubricating driving gear is easy to popularize and apply, and is in accord with the tendency of technological development in the current society.
Description
Technical field
The utility model belongs to the ploughing machine technical field, especially relates to a kind of self-lubricating type actuation gear.
Background technique
Gear is the intermeshing mechanical parts that tooth is arranged of energy, and its application in mechanical transmission and whole mechanical field is extremely extensive.Actuation gear is that car is advanced or the vitals when falling back, existing actuation gear exists: working life is short, and contact ratio is low, and bearing capacity is poor, the oil storage poor performance, that is to say, mostly existing gear generally is the artificial lubricant oil that adds, and the method can satisfy usage requirement to a certain extent, but, its lubricant oil of such structure is easily withered, causes friction factor to become large, has virtually shortened the working life of gear.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of gear [application number: 200720159453.4], comprises gear shaft, key, it is characterized in that being arranged on gear shaft through key by a plurality of spur gear sheets, the spur gear sheet is successively around axial-rotation, and the tooth between adjacent straight gear sheet is interlaced.
Such scheme has been alleviated to a certain extent existing contact ratio and overlap ratio and has been hanged down and the poor problem of bearing capacity, but still exists: the technical problems such as lubrication effect is relatively poor and easy to wear.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, but selflubricating and the self-lubricating type actuation gear that can extend service life of gear.
For achieving the above object, the utility model has adopted following technical proposal: this self-lubricating type actuation gear comprises the gear mass with some even distribution teeth, be provided with center hole at the gear mass center, it is characterized in that, described teeth both ends of the surface are respectively equipped with chamfer surface, top in each teeth has the plane, is provided with at least one spiral oil storage tank on center bore inner wall, and described gear mass thickness equates with teeth thickness.Obviously, the utility model design is more reasonable, has virtually extended working life, particularly reduced friction factor, but its selflubricating has reduced user cost, is easy to apply, and meets the trend of current social technical development.
In above-mentioned self-lubricating type actuation gear, described spiral oil storage tank groove depth is 0.04mm～2mm, and groove width is 0.04mm～2mm, and the pitch of grooves between two adjacent grooves is 0.04mm～2mm.The groove depth here, groove width and pitch of grooves can be formulated according to the requirement of reality.
As another scheme, in above-mentioned self-lubricating type actuation gear, be provided with in described center hole and be positioned at aperture place and be provided with ring-shaped step, and the center line of this ring-shaped step overlaps with the center line of center hole.Can be used for the location, fixed.
In above-mentioned self-lubricating type actuation gear, described center hole surface roughness is≤Ra0.8.
Compared with prior art, the advantage of this self-lubricating type actuation gear is: it is more reasonable to design, and has virtually extended working life, particularly reduced friction factor, but its selflubricating has reduced user cost, be easy to apply, meet the trend of current social technical development.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
In figure, gear mass 1, teeth 11, chamfer surface 11a, plane 11b, center hole 12, spiral oil storage tank 12a, ring-shaped step 13.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this self-lubricating type actuation gear comprises the gear mass 1 with some even distribution teeth 11, be provided with center hole 12 at gear mass 1 center, these center hole 12 surface roughnesses are≤Ra0.8, be respectively equipped with chamfer surface 11a in teeth 11 both ends of the surface, have plane 11b at the top of each teeth 11, be provided with at least one spiral oil storage tank 12a on center hole 12 inwalls, described gear mass thickness equates with teeth thickness.Obviously, the present embodiment design is more reasonable, has virtually extended working life, particularly reduced friction factor, but its selflubricating has reduced user cost, is easy to apply, and meets the trend of current social technical development.
Specifically, the spiral oil storage tank 12a groove depth of the present embodiment is 0.04mm～2mm, groove width is 0.04mm～2mm, pitch of grooves between two adjacent grooves is 0.04mm～2mm, the groove depth here, groove width and pitch of grooves can be formulated according to the requirement of reality, optimized project, and the groove depth of the spiral oil storage tank 12a of the present embodiment is 0.06mm, groove width is 0.1mm, and pitch of grooves is 0.1mm.In addition, be provided with in center hole 12 and be positioned at aperture place and be provided with ring-shaped step 13, and the center line of this ring-shaped step 13 overlaps with the center line of center hole 12.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as gear mass 1, teeth 11, chamfer surface 11a, plane 11b, center hole 12, spiral oil storage tank 12a, ring-shaped step 13, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
