Abstract
The utility model relates to a cam device which comprises a cam body. Transmission gears are evenly arranged on the outer circumference of the cam body which is in a cylindrical structure. The number of the transmission gears is 6-12. Each two transmission gears are a pair and are evenly distributed on the outer circumference of the cam body in a vertically parallel mode. The transmission gears are arranged outside the cylindrical cam body so that power can be better transmitted. Meanwhile, each two transmission gears are a pair so that stability of a cam in a transmission process is ensured.
Description
Technical field
The utility model relates to a kind of cam, relates in particular to the cam gear that a kind of heavy machinery is used.
Background technique
Cam mechanism is generally by cam, the higher pair mechanism that three members of driven member and frame form.Cam is usually made continuous constant speed and is rotated, and driven member according to requirements designs and makes it obtain the motion of certain rule.Cam mechanism can be realized complicated motion requirement, is widely used in various automated and semi-automatic mechanical devices.
Cam mechanism is comprised of two part moving parts usually, i.e. cam and follower, and both all are fixed on mounting.Cam gear is quite diverse, therefore nearly all any action all can be through mechanism generation thus.
Cam can be defined as the parts with curved surface or crank slot, utilizes its swing or revolution, can make another assembly-follower that predefined motion is provided.The large section in the path of follower is limited in a chute, to obtain toward covering motion.In the stroke of its reply, sometimes rely on the weight of itself, but some mechanism is the definite action of acquisition, often with the power of spring as reply, some utilizes guide groove, and it is being moved on specific path.
The design people, actively research and innovation in addition, to founding a kind of cam gear of new structure, make it have more practicability.
The model utility content
The technical problem that mainly solves of the present utility model is to make the cam gear motion reliable, rational in infrastructure, reduces friction, thereby more is suitable for practicality, and have the value on industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.A kind of cam gear according to the utility model proposes comprises cam body, and described cam body periphery is provided with driving cog uniformly.
Aforementioned cam body is cylindrical structure.
Aforementioned driving cog is 6 ~ 12.
Two of aforementioned driving cogs are a pair of, the excircle that is distributed on cam body that the up and down is parallel.
By technique scheme, cam gear of the present utility model has following advantages at least:
By the cam body outer installment driving cog at cylindrical shape, better transferring power, simultaneously, two of driving cogs are a pair of, have guaranteed the stability in the cam transmittance process.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
Description of drawings
Fig. 1 is the structural representation of the utility model cam gear.
Embodiment
Be to reach technological means and the effect that predetermined model utility purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, embodiment of the present utility model be described in detail as follows.
Cam gear of the present utility model as shown in Figure 1 comprises cam body 1, and cam body 1 is cylindrical structure, and periphery is provided with 8 driving cogs 2 uniformly, and 2 two of driving cogs are a pair of, the excircle that is distributed on cam body 1 that the up and down is parallel.Wherein the material of cam body is the alloyed steels such as 42CrMo, 40 CrMo or GCr15.
the above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
