Problems solved by technology

However, the dust cover of this structure is relatively complicated and costly. When the engine works under harsh conditions such as dust and sand, its sealing structure is prone to failure, resulting in unstable sealing performance and can no longer meet the requirements of dustproof capability. The application of sealed and dust-proof structure is imperative

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0014] like figure 1 As shown, a fully sealed dust-proof structure at the front end of the fan shaft is characterized in that it includes a pulley 2, a fan shaft 7, a bearing A10, a bearing B11, a spacer A3, a baffle 5, a circlip 9 for the hole, and a front Dust cover 1, rear dust cover 4, spacer B6, bearing A10 and bearing B11 are installed on the fan shaft 7 in order from left to right, and the outer ring of bearing A10 and bearing B11 interferes with the inner hole of pulley 2 Cooperate, a spacer A3 is also installed on the fan shaft 7 between the bearing A10 and the bearing B11, the two ends of the spacer A3 are pressed against the inner rings of the bearing A10 and the bearing B11, and the baffle 5 is fixed on the fan shaft by bolts 8 7, and press it on the inner ring o...

Abstract

The invention relates to a fan shaft member front fully-sealed dustproof structure. The fan shaft member front fully-sealed dustproof structure comprises a belt pulley (2), a fan shaft (7), a bearing A (10) a bearing B (11), a spacer bush A (3), a baffle (5), an internal circlip (9), a front dustproof cover (1), a rear dustproof cover (4) and a spacer bush B (6). The bearing A (10) and the bearing B (11) are sequentially mounted on the fan shaft (7) from left to right in a matched mode; the front dustproof cover (1); the front dustproof cover (1) is embedded inside a ring-shaped groove in the inner hole wall on one side of the belt pulley (2); the rear dustproof cover (4) and the spacer bush B (6) sleeve the fan shaft (7); the edge of the rear dustproof cover (4) is embedded into the ring-shaped groove in the end surface of the belt pulley (2); the spacer bush B (6) is arranged between the rear dustproof cover (4) and the side surface of the fan shaft (7). The fan shaft member front fully-sealed dustproof structure has the advantages of being simple in structure, low in cost and fully isolated and sealed.

Description

technical field [0001] The invention relates to a dustproof structure of a fan shaft part, in particular to a fully sealed dustproof structure at the front end of the fan shaft part. Background technique [0002] The fan shaft parts are generally installed at the lower part of the front wheel train of the engine, and the working conditions are harsh. In order to prevent dust and mud from entering the product and causing failure, it is often necessary to cover the internal structure of the pulley. The existing non-fully sealed metal The dustproof cover is mostly made of plate blanking, punching, forming, and flanging, and then the dustproof cover is tightened by hexagonal flange bolts to achieve the purpose of dustproofing. However, the dust cover of this structure is relatively complicated and costly. When the engine works under harsh conditions such as dust and sand, its sealing structure is prone to failure, resulting in unstable sealing performance and can no longer meet ...
