Description
Technical field
The utility model relates to the dustproof construction of fixed belt tension wheel assembly, particularly the hermetically sealed dustproof construction of a kind of fixed belt tension wheel assembly.
Background technique
Fixed belt tension wheel assembly is generally arranged on place on the lower, position on motor front-end wheel system, operating mode is severe, bearing failure is caused for minimizing dust and mud etc. enter interiors of products, the internal structure of belt pulley is often needed to hide, existing dust cover, 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, 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, the hermetically sealed dustproof construction of fixed belt tension wheel assembly of easy to operate and good sealing effect.
The purpose of this utility model is achieved through the following technical solutions: the hermetically sealed dustproof construction of a kind of fixed belt tension wheel assembly, it comprises belt pulley, end ring I, end ring II, dust cover, bearing and circlip for hole, bearing fit is arranged on inside belt pulley, belt pulley endoporus side is provided with the step of restriction belt pulley outer ring, opposite side offers circlip for hole groove and dust cover draw-in groove successively, circlip for hole is arranged in circlip for hole groove, circlip for hole contacts with the opposite side of bearing outer ring and coordinates, the both sides of bearing inner race are also separately installed with end ring I and end ring II, end ring I and end ring II are bolted, dust cover is fitted in described dust cover draw-in groove.
Described bearing is double row bearing.
The threaded end of described bolt is also set with O type rubber seal, and the exterior edge face of end ring I has the deep gouge coaxial with bolt, and O type rubber seal is contained in described deep gouge.
The utility model has the following advantages: the hermetically sealed dustproof construction of the utility model fixed belt tension wheel assembly is more simple compared with conventional dustproof construction, cost is lower, be set with O type rubber seal between bolt and end ring I, on belt pulley hole wall, in processing, caulking groove plays locking effect; Use wooden mallet to be enclosed within pulley groove by plastic dust lid, thus make bearing be in whole sealing status, greatly can improve life of product, and operation is comparatively simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-belt pulley, 2-end ring I, 3-end ring II, 4-dust cover, 5-bolt, 6-circlip for hole, 7-bearing, 8-O type rubber seal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, the hermetically sealed dustproof construction of a kind of fixed belt tension wheel assembly, it comprises belt pulley 1, end ring I 2, end ring II 3, dust cover 4, bearing 7 and circlip for hole 6, bearing 7 cooperation is arranged on inside belt pulley 1, belt pulley 1 endoporus side is provided with the step of restriction belt pulley 1 outer ring, opposite side offers circlip for hole groove and dust cover draw-in groove successively, circlip for hole 6 is arranged in circlip for hole groove, circlip for hole 6 contacts with the opposite side of bearing 7 outer ring and coordinates, the both sides of bearing 7 inner ring are also separately installed with end ring I 2 and end ring II 3, end ring I 2 is connected by bolt 5 with end ring II 3, dust cover 4 is fitted in described dust cover draw-in groove.
Described bearing 7 is double row bearing.
The threaded end of described bolt 5 is also set with O type rubber seal 8, the exterior edge face of end ring I 2 has the deep gouge coaxial with bolt 5, and O type rubber seal 8 is contained in described deep gouge.
Working procedure of the present utility model is as follows: during assembling, first bearing 7 is installed in belt pulley 1, and the step surface close contact of the outer ring of bearing 7 and belt pulley 1 endoporus, the opposite side of bearing 7 installs circlip for hole 6, the outer ring of bearing 7 is fixed, again end ring I 2 and end ring II 3 are arranged on bearing 7 inner ring both sides respectively, and strain connection by bolt 5, O type rubber seal 8 is packed into from the threaded end of bolt 5, and be stuck in the deep gouge of end ring I 2 exterior edge face, with wooden mallet, dust cover 4 is enclosed within pulley groove, thus make bearing 7 be in whole sealing status, greatly can improve life of product.
