Background
In the mechanical industry, a plurality of workpieces need to be cleaned, electroplated and the like, the use requirements of the workpieces are ensured, and partial products need to be processed by using an etching process. Washing, electroplating and etching process's transport mechanism conveys on the gyro wheel, it all is some chemical solution to wash, electroplate and etch, some chemical liquid medicine has strong acid, strong alkali, the characteristics of strong corrosivity, prior art's roller device corrosion resistance is poor, easy chemical solution corrodes in continuous production process, cause the unable normal use of roller device, the change that need carry out the gyro wheel, because of the cost of gyro wheel is high, maintenance cost is very high when roller device damages, increase manufacturing cost.
The utility model provides a corrosion-resistant dismantlement formula long-life gyro wheel device solves above-mentioned technical problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve prior art's gyro wheel device corrosion resistance poor, the easy chemical solution that is corroded in continuous production process causes the unable normal use of gyro wheel device, needs to carry out the change of gyro wheel, and because of the cost of gyro wheel is high, maintenance cost is very high when gyro wheel device damages, increases manufacturing cost's technical problem, provides a corrosion-resistant dismantlement formula long-life gyro wheel device and solves above-mentioned technical problem.
The utility model provides a corrosion-resistant dismantlement formula long-life gyro wheel device which characterized in that: including gyro wheel, A hollow axle, B hollow axle, bolt, screw hole and seal ring, the external diameter of B hollow axle is less than the internal diameter of A hollow axle, and B hollow axle can assemble in the inside of A hollow axle, A hollow axle and B hollow axle all are equipped with the screw hole and correspond each other, seal ring sets up the hookup location at A hollow axle and B hollow axle, the material that A hollow axle and B hollow axle used is the bearing steel, the outside of A hollow axle and B hollow axle all is equipped with the polytetrafluoroethylene shell, the material of gyro wheel is polytetrafluoroethylene, seal ring's material is perfluoroelastomer, A hollow axle and B hollow axle pass through bolted connection together.
Further, the surfaces of the bearing steel used for the hollow shaft A and the hollow shaft B are subjected to nickel plating treatment.
Further, the material used for the bolt is SUS304 and the surface is nickel-plated.
Compared with the prior art, the utility model has the advantages that: in the in-service use process, because the hollow core axle of A and the hollow core axle of B are for dismantling the connection, if the hollow core axle of a certain position damages because of corroding, can tear the bolt off and change, seal ring corrosion damage also can change, avoid the whole root of gyro wheel device to change, can not cause the waste of resource, the maintenance cost of gyro wheel has been reduced, again through wrapping up the polytetrafluoroethylene shell in the outside of hollow core axle, the gyro wheel that perfluororubber seal ring and polytetrafluoroethylene preparation formed, the corrosion resisting property of gyro wheel device has been improved greatly, the life of extension gyro wheel device.
