Description
Technical Field
The utility model belongs to the spray gun rotating machinery structure field, concretely relates to eliminate carbon bits increase of service life's mechanical structure.
Background
The atmospheric plasma surface cleaning machine generates plasma by compressed air passing through discharge ionization between an electrode and a spray head, and then the plasma is sprayed out from a spray opening of the spray head. The diameter of the nozzle cannot be large to satisfy the stability and the duration of discharge, so that the surface area which can be treated when the nozzle is used directly is small. If the large area is treated, the efficiency is low, the treatment area is formed from point to line by a method of continuously rotating a spray head at present, and then the cleaning area is enlarged from line to surface by moving the whole spray gun or the surface to be treated, so that the efficiency is improved.
The rotating mechanical mechanism of the existing spray gun is generally characterized in that a carbon brush ring is sleeved outside a belt pulley, a graphite carbon brush is arranged in a bearing seat and is in frictional contact with the carbon brush ring (as shown in figure 1), and the structure has the defects that graphite carbon chips are generated due to the friction between the graphite carbon brush rotating at a high speed and the carbon brush ring, and the service life of the bearings is influenced when the carbon chips enter the bearings at two sides; if grease is injected into the two ends of the carbon brush ring for sealing, the viscous belt pulley influences high-speed rotation when grease and carbon dust mixture can be solidified in a later period.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mechanical structure for solving the technical problem and prolonging the service life of carbon scraps.
The utility model discloses a realize its technological effect and the solution that adopts does:
a mechanical structure for eliminating carbon dust and prolonging the service life comprises an air inlet seat, a bearing seat, a belt pulley, a bearing, a graphite carbon brush and a carbon brush ring; the air inlet seat is internally provided with a mounting hole and a chip removal hole; one end of the bearing seat is fixedly connected with the air inlet seat; the belt pulley is rotatably arranged between the outer side of the air inlet seat and the inner side of the bearing seat; the bearing is arranged between the bearing seat and the belt pulley; the graphite carbon brush is arranged in the mounting hole; the carbon brush ring is arranged at one end of the belt pulley, and one surface of the carbon brush ring is in frictional contact with the graphite carbon brush; a chip removal cavity is formed among the carbon brush ring, the air inlet seat, the bearing seat and the graphite carbon brush; the chip removal cavity is communicated with the chip removal hole.
Preferably, the bearing is a ball bearing.
Preferably, a screw and a spring are further arranged in the mounting hole; the spring is arranged between the screw and the graphite carbon brush.
The utility model has the advantages that: the carbon brush ring is installed in the radial direction on one side of the two bearings instead of the axial direction between the two bearings, the carbon brush rubs the end face of the carbon brush ring, and carbon chips generated by friction are blown out from a chip removal hole by compressed air from a gap between the belt pulley and the air inlet seat through a gap between the bearing seat and the carbon brush ring. Therefore, carbon dust can not enter the bearing completely, grease injection sealing is not needed, and the purposes of reducing maintenance and prolonging service life are achieved.
