Background technique
Fan shaft part is generally arranged on place on the lower, position on motor front-end wheel system, operating mode is severe, cause losing efficacy for minimizing dust and mud etc. enter interiors of products, the internal structure of belt pulley is often needed to hide, existing non-sealed metal dust-proof cover is dust-proof, most employing sheet material blanking, punching, shaping, flange form, and then strain dust cover by hexagon flange bolt, thus reach dust-proof object.But the dust cover relative complex of this structure, cost are higher, when motor works under the mal-condition such as dust, silt, its sealing configuration easily lost efficacy, and caused sealability unstable, cannot meet dirt exclusion capabilities requirement, therefore the application of hermetically sealed dustproof construction is imperative.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, cost is low and the hermetically sealed dustproof construction in fan shaft part front end of good seal performance.
The purpose of this utility model is achieved through the following technical solutions: the hermetically sealed dustproof construction in a kind of fan shaft part front end, it is characterized in that: it comprises belt pulley, fan shaft, bearing A, bearing B, spacer A, baffle plate, circlip for hole, front dust cover, rear dust cover and spacer B, bearing A and bearing B successively cooperation is from left to right arranged on fan shaft, and the endoporus interference fit of the outer ring of bearing A and bearing B and belt pulley, fan shaft between bearing A and bearing B is also provided with spacer A, the both ends of the surface top of spacer A is pressed on the inner ring of bearing A and bearing B, baffle plate is bolted on the end face of fan shaft, and be pressed on the inner ring of bearing A, circlip for hole is arranged in the draw-in groove that is arranged on belt pulley inner hole wall, and be pressed on the outer ring of bearing B, front dust cover, rear dust cover and spacer B, front dust cover is embedded in the inner hole wall annular groove of belt pulley side, rear dust cover and spacer B are sleeved on fan shaft, and the edge of rear dust cover is embedded in belt pulley end face annular groove, spacer B is between rear dust cover and fan shaft side.
Described bearing A and bearing B is rolling bearing.
Described front dust cover is the plastic dust lid of molding and forming.
The utility model has the following advantages:
1, the hermetically sealed dustproof construction of the utility model fan shaft assembly is more simple compared with conventional dustproof construction, and cost is lower.
2, front dust cover is embedded in the annular groove of belt pulley inner hole wall, rear dust cover is embedded in the annular groove of belt pulley end face, and compressed by axle sleeve B, front dust cover, rear dust cover and belt pulley endoporus is made to form a complete airtight space, rolling bearing is arranged in belt pulley endoporus, and be isolated from the outside, good dustproof effect, is conducive to the working life of improving fan shaft assembly.
3, front dust cover is embedded in the annular groove of belt pulley inner hole wall, and difficult drop-off plays anti-loose effect, improves the stability of fan shaft component sealing performance.
