Description
Technical field
The utility model is related to engine blower axle technical field, and in particular to a kind of fan shaft part.
Background technology
Fan shaft part is engine part important component, is frequently utilized for supporting fan, and drive by belt pulley
Fan rotates, and provides radiating air quantity to engine, takes away the heat that cooling system is transmitted from engine, it is ensured that engine exists
Operation steady in a long-term under different operating modes.Transmission power also is provided to engine accessory power ratings such as generator, air conditioners simultaneously, is to start
The intermediate shaft part of machine front end train.Current fan shaft part structure, sub- number of parts is more, manufactures, processes, is assembled into
This height, and in use, using current structure mode, because fan rotational strength is big, easily there is the part axle such as bent axle
To play, influence stability, and muddy water, the dust in the external world to be easily accessible inside fan shaft part, reduce fan shaft part
Use reliability.
Utility model content
The utility model provides a kind of simple in construction for above-mentioned technical problem, and manufacturing cost is low, highly reliable fan
Axle portion part.To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of fan shaft part, including fan shaft, fan pulley, in addition to bearing I, bearing II, spacer, baffle plate, spiral shell
Bolt, back-up ring, the inner ring of the bearing I and the bearing II are directly interference fitted with the fan shaft；The bearing I and the axle
The spacer is distributed between holding II；The fan shaft front end is provided with bolt hole, and the bolt correspondence bolt hole will be described
Baffle plate is fixed on the fan shaft front end, and the bearing I is extruded；The back-up ring is distributed in the rear of bearing II,
And the bearing II is extruded.
Further, the outer ring of the fan pulley and the bearing I and the bearing II is interference fitted.
Further, the back-up ring rear is additionally provided with rear dust cap, and the rear dust cap is pressed abd fixed on the fan shaft
On, and the fan pulley is sealed by using labyrinth sealing mode.
Further, the fan pulley front end is additionally provided with preceding dust cap, the preceding dust cap and the fan belt
Wheel is interference fitted.
Further, it is distributed at the shoulder of the fan shaft at the rear of bearing II and is handled using back chipping, effectively solution
Certainly the problem of stress undue concentration.
Further, the back-up ring is spacing to fan pulley progress, prevents the fan pulley axial float,
Improve stability.
The beneficial effect of the utility model compared with prior art：The utility model need not compared to conventional fan axle portion part
The parts such as spacer, effectively reduce the quantity of sub- part, reduce production cost；It is critical that the utility model is by using complete
New overall fixed structure, simple in construction, the processing compared to legacy device is easier to production, and quality is easier control, and cost is big
Big reduction；And the utility model occurs without the play of the parts such as bent axle, fan pulley in actual motion, stability is good, has
Effect improves the security and efficiency of part operation；Meanwhile, front and rear dust cap has also prevented the muddy water in the external world, dust and has entered inlet air completely
Axle components interior is fanned, fault rate is effectively reduced, component life is improved.

Embodiment
As shown in Fig. 1~2, a kind of fan shaft part, including fan shaft 10, fan pulley 4, and bearing I 5, bearing
II 7, spacer 6, baffle plate 3, bolt 2, back-up ring 8, inner ring and the direct mistake of the fan shaft 10 of the bearing I 5 and the bearing II 7
It is full of cooperation；The spacer 6 is distributed between the bearing I 5 and the bearing II 7；The front end of fan shaft 10 is provided with bolt hole,
The baffle plate 3 is fixed on the front end of fan shaft 10 by the correspondence of bolt 2 bolt hole, and the bearing I 5 is carried out
Extruding；The back-up ring 8 is distributed in the rear of bearing II 7, and the bearing II 7 is extruded, in the present embodiment, institute
State the back-up ring 8 and also act as and the fan pulley 4 is carried out spacing, prevent the axial float of fan pulley 4, improve
Stability.The outer ring of the fan pulley 4 and the bearing I 5 and the bearing II 7 is interference fitted.The back-up ring 8
Rear is additionally provided with rear dust cap 9, and the rear dust cap 9 is pressed abd fixed on the fan shaft 10, and close by using labyrinth type
Envelope mode is sealed to the fan pulley 4.The front end of fan pulley 4 is additionally provided with preceding dust cap 1, described preceding dust-proof
Lid 1 is interference fitted with the fan pulley 4, is moved with the synchronous rotary of fan pulley 4.Meanwhile, in order to solve stress
Handled at the problem of undue concentration, the shoulder for the fan shaft 10 that will be distributed over the rear of bearing II 7 using back chipping.This reality
Simple with new structure, production cost is low, and quality is easily controllable, and stability is good in operation, effectively improves equipment fan work
Make efficiency, greatly reduce equipment failure rate, using effect is good.
