Abstract
The invention provides an anti-explosion cam, comprising a cam body, wherein an anti-explosion protection layer is arranged on the exterior of the cam body. The anti-explosion cam is simple and compact in structure, low in manufacturing cost and good in impact resistance, and has an excellent noise reduction effect; and with the adoption of the anti-explosion protection layer, the abrasion can be decreased, the mechanical spark generated during the abrasion can be reduced, the occurrence probability of an explosion is lowered and the service life of the cam is prolonged.
Description
Technical field
The present invention relates to a kind of explosion-proof cam.
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.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defects that prior art exists, and provides a kind of reliable operation, the explosion-proof cam of long service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of explosion-proof cam, 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 present invention 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 one embodiment of the invention structural representation.
Embodiment
The invention will be further described 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.
Described explosive-proof protector layer 1 is the wear-resistant plastic protective layer, is beneficial to improve the impact resistance of cam.
Embodiment 2:
Present embodiment and embodiment's 1 difference is: described explosive-proof protector layer is layer of brass, is beneficial to improve the hardness of cam face.All the other are with embodiment 1.
Claims (3)
1. an explosion-proof cam comprises cam body, it is characterized in that, described cam body is provided with the explosive-proof protector layer outward.
2. explosion-proof cam according to claim 1 is characterized in that, described explosive-proof protector layer is the wear-resistant plastic protective layer.
3. explosion-proof cam according to claim 1 and 2 is characterized in that, described explosive-proof protector layer is layer of brass.
