Abstract
The utility model discloses a main shaft of printing machine, including the axis body, an axis body pot head have flange structure, axis body and flange structure surface cover have chromium-plated layer. The thickness of the chromium coating is 0.05 mm. The chromium coating can be coated on the outer surfaces of the shaft body and the flange structure by adopting the processes of electroplating and the like in the prior art. The flange structure on evenly distributed a plurality of be used for passing the screw of bolt. The chromium coating is coated on the outer surfaces of the shaft body and the flange structure, so that the corrosion resistance is greatly improved, the surface hardness is increased, and the tolerance is reduced during shaft body processing. The service life of the parts is prolonged.
Description
Technical field
The utility model relates to a kind of metal parts, relates in particular to a kind of main shaft of printing machine.
Background technology
Axle is that mechanical industry is used extensive, strict auxiliary equipment and basic part.Main frame in the every field such as industry, agricultural, national defence, science and technology and household electrical appliance, its precision, performance, life-span, reliability and each economic target, all close getting in touch arranged, and the axle industrial expansion is also concerning the manufacture level of China's major technologies and equipment and the export capacity of plant equipment with axle.
Axle is in use because the intrusion of water, corrosive substance (lacquer, coal gas etc.), lubricant is improper, condensing of steam and with water droplet, stall when high temperature wets more, antirust bad in the transportation, the keeping state is improper, a phenomenon of using improper or the like reason can make axle get rusty and corrode, its bearing capacity, running accuracy and antifriction performance etc. can change, axle be in case when fortuitous event such as being damaged, its machine, equipment stall will occur, function various anomalies such as sustain damage.
Therefore reduce the loss of axle, be very important the service life that prolongs axle.Prior art for the anticorrosion of axle, it is anti-that to get rusty generally all be to be coated with the antiseptic and rustproof grease of one deck on the surface of axle.But these antiseptic and rustproof greases are unfavorable for environmental protection owing to be petroleum chemicals all; The grease that has is inflammable, and what have is volatile; Simultaneously, after axle used a period of time, the antiseptic and rustproof effect of grease will disappear.
Summary of the invention
The utility model provides a kind of anticorrosion, antirust main shaft that is beneficial to accurately machined printing machine
A kind of main shaft of printing machine comprises axis body, and described axis body one end is with flange arrangement, and axis body and flange arrangement outer surface are covered with chromium coating.
The thickness of described chromium coating is 0.05 millimeter.
Described chromium coating can adopt technology such as to be electroplated and overlays on axis body and flange arrangement outer surface in the prior art.
Evenly distributing on the described flange arrangement, several are used to pass the screw of bolt.
The main shaft of the utility model printing machine has been brought up to anti-corrosive properties greatly after axis body and flange arrangement outer surface are covered with chromium coating, also increased case hardness, adds at axis body and has reduced tolerance man-hour.Also prolonged the service life of part.
Description of drawings
Fig. 1 is the main axle structure schematic diagram of the utility model printing machine;
Fig. 2 is an A part enlarged drawing among Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, the main shaft of the utility model printing machine comprises axis body 2, and axis body 2 one ends are with flange arrangement 3, and axis body 2 and flange arrangement 3 outer surfaces are covered with chromium coating 1.
The thickness of chromium coating 1 is 0.05 millimeter.
Evenly distributing on the flange arrangement 3, several are used to pass the screw of bolt.Flange arrangement 3 tops are broken section among Fig. 1, visible screw 4.
Brought up to anti-corrosive properties greatly after axis body 2 and flange arrangement 3 outer surfaces are covered with chromium coating 1, also increased case hardness, added at axis body 2 and reduced tolerance man-hour.Also prolonged the service life of part.
Claims (3)
1, a kind of main shaft of printing machine comprises axis body (2), it is characterized in that: described axis body (2) one ends are with flange arrangement (3), and axis body (2) and flange arrangement (3) outer surface are covered with chromium coating (1).
2, the main shaft of printing machine as claimed in claim 1 is characterized in that: the thickness of described chromium coating (1) is 0.05 millimeter.
