Abstract
An anti-explosion cam provided with an anti-explosion protective layer comprises a cam body, wherein the anti-explosion protective layer is arranged outside the cam body. The anti-explosion cam provided with the anti-explosion protective layer is simple and compact in structure, low in manufacturing cost, good in anti-impact effect, good in noise damping performance, and good in sound-absorption effect. The anti-explosion protective layer is capable of reducing abrasion, reducing mechanical sparks caused by abrasion, lowering the occurrence possibility of explosions, and prolonging the service life of the cam.
Description
Technical field
The utility model relates to a kind of explosion-proof cam with explosive-proof protector layer.
Background technique
Because industries such as petroleum and petrochemical industry, coal productions, manufacturing process has produced a large amount of inflammable gass, has formed explosive gas atmosphere around manufacturing equipment.Along with industrialized fast development, production process is increasingly automated, electrical equipment and instrument and apparatus are used ubiquitous, and also extensive use in the automation electrical equipment of cam, though present employed cam mechanism can be realized any adjusting at aspects such as timing controlled, but what adopt is the line contact form, and easy to wear, working life is shorter.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defects that prior art exists, and provides a kind of reliable operation, the explosion-proof cam with explosive-proof protector layer of long service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of explosion-proof cam with explosive-proof protector layer, comprise cam body, and described cam body is provided with the explosive-proof protector layer outward.
Further, described explosive-proof protector layer is the wear-resistant plastic protective layer, is beneficial to improve the impact resistance of cam.
Further, described explosive-proof protector layer also can be layer of brass, is beneficial to improve the hardness of cam face.
The utility model is simple in structure, compact, low cost of manufacture, and good impact resistance, noise damping is good, has good erasure effect; The explosive-proof protector layer can reduce wearing and tearing, and the mechanical spark that produces when reducing wear reduces the probability of happening that explodes, and prolongs the working life of cam.
Description of drawings
Fig. 1 is the utility model one example structure schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
With reference to Fig. 1, present embodiment comprises cam body 2, the described cam body 2 outer explosive-proof protector layers 1 that are provided with.
