Abstract
The utility model discloses a novel fan shaft structure of an engine. The novel fan shaft structure of the engine comprises a fan shaft seat, a separating sleeve, a rear dust cover, a check ring, a fan sealing bearing, a fan belt wheel, a cylindrical pin, a baffle, a front dust cover and a bolt. The novel fan shaft structure of the engine is characterized in that a fan shaft is provided with fixed mounting holes, the front dust cover is arranged at the front end of the fan shaft, the rear dust cover is arranged at the rear end of the fan shaft, and clearances are arranged between the outer diameter of the rear dust cover and the belt wheel and between the outer diameter of the front dust cover and the belt wheel. Due to the fact that the fan shaft seat is strengthened, the number of the mounting holes of a fan shaft component is changed to be six from four. Therefore, the aim of preventing the phenomena that the fan shaft seat cracks and the mounting bolt is broken is achieved. Dust is prevented from entering the fan shaft component, the bearing is prevented from falling apart, pressing and bunging up a water tank, and the situation that the rotation of a fan is stopped due to the fact that the fan shaft component and the bearing are jammed is avoided.
Description
Technical field
The utility model relates to a kind of engine new fan shaft structure.
Background technique
At present, in service at this type of fan shaft part, after supporting magnetic clutch or silicon oil clutch, fan shaft front end weight strengthens, the situations such as and fan shaft is very few with the engine body connecting bolt, and fan shaft base cracking, the bolt that causes due to problems such as vibrations when car load moves is disconnected; Thereby cause the bearing of fan shaft part stuck owing to there being dust to enter in fan shaft part; Fan shaft part causes bearing to fall apart on unlubricated dose of operation a period of time aft-fan spindle unit bearing;Result causes the original equilibrium forfeiture of fan, and the axial motion quantitative change is large, damages the ring water tank.
Summary of the invention
The purpose of this utility model is to provide the structure of 6 fan attachment axles of a kind of use, by optimization and the increase to original fan shaft mounting hole, makes fan shaft not easy to crack.And guarantee that the fan shaft construction bolt does not rupture.And solving lubrication problem by the straight pin stuffing box bearing, the rear and front end installs dust cover additional and solves the problem that dust enters, and solves after the bearing long-play unlubricated fat and dust and enters and cause the stuck phenomenon of bearing to occur.Carry out improved New Type of Fan spindle unit on the original structure basis.
Technical solution of the present utility model is such: a kind of engine new fan shaft structure, comprise fan bearing base, spacer, rear dust cover, back-up ring, fan stuffing box bearing, fan pulley, straight pin, baffle plate, front dust cover, bolt, it is characterized in that described fan shaft part is by changing 6 mounting holes to fan bearing base (1) into by 4 original mounting holes, and after the rear and front end is sealed with dust cover (3), front dust cover (9), bearing changes fan stuffing box bearing (5) into.
Fan stuffing box bearing (5) is used the straight pin bearing, dust cover (3) after installing between fan stuffing box bearing (5) and spacer (2).
Dust cover (9) before fan bearing base (1) front end is installed.
The utility model fan shaft part has following beneficial effect:
1, prevent that fan bearing base from ftractureing, preventing the construction bolt fracture;
2, prevent that dust from entering fan shaft part;
3, prevent from causing because the fan shaft part bearing is stuck the fan stall;
4, prevent from breaking water tank after bearing from falling apart.
Description of drawings
It is such that structure of the present utility model consists of:
Fig. 1 is that a kind of engine new fan shaft of the utility model structural entity structure is installed assembling stereogram.
Fig. 2 is the plan view of a kind of engine new fan shaft of the utility model structure.
Fig. 3 is the right elevation of a kind of engine new fan shaft of the utility model structure.
Fig. 4 is that a kind of engine new fan shaft of the utility model structural entity structure is installed sectional arrangement drawing.
Reference character: fan bearing base (1), spacer (2), rear dust cover (3), back-up ring (4), fan stuffing box bearing (5), fan pulley (6), straight pin (7), baffle plate (8), front dust cover (9), bolt (10).
Embodiment
Most preferred embodiment of the present utility model is such, referring to figs. 1 through shown in Figure 4, and the utility model fan shaft part, described fan shaft part namely changes 6 mounting holes into by 4 original mounting holes by the reinforcement to fan bearing base (1).And the position of mounting hole is optimized.Thereby reach control fan bearing base cracking, the phenomenon of construction bolt fracture occurs; Adopt simultaneously the rear dust cover (3) of sealed at both ends its rear dress, the front dust cover (9) of the place ahead dress, bearing changes fan stuffing box bearing (5) into, described fan shaft part is avoided because dust enters stuck that fan shaft part causes, simultaneously the bearing failure because adopting the fan stuffing box bearing to avoid lubricating grease to run off and cause.
Should leave the gap in the middle of the rear dust cover (3) of dust cover (Fig. 4) and fan pulley (6) mating groove, before and after preventing, dust cover (9,3) turns with fan belt pulley (6) is same.Straight pin (7) prevents that the fixed installation bolt (10) of fan shaft part from rotating with fan belt pulley (6) phenomenons such as bolt (10) fracture that cause and occuring.Concrete scheme is: fan bearing base (1) has front dust cover (9), rear dust cover (3) with front end and back end between fan pulley (6) is connected, before and after the installation of fan pulley (6), the corresponding positions of dust cover (9,3) is equipped with groove kiln dress front dust cover (9), rear dust cover (3), and is gapped between front and back dust cover (9,3) and fan pulley (6) when mounted.
Mounting process is: straight pin (7) passes baffle plate (8) and is enclosed in fan bearing base (1) front end, and fan stuffing box bearing (5) is used the straight pin bearing.Spacer (2) is arranged on the step shaft shoulder of fan bearing base (1), dust cover (3) after then filling again, fan stuffing box bearing (5), back-up ring (4) fan pulley (6) inner chamber of packing into, fan pulley (6) suit is entered fan axle bed (1), load onto baffle plate (8), straight pin (7) passes baffle plate (8) and is inserted in fan bearing base (1) end in fan bearing base (1) end, front dust cover (9) veneer is contained in baffle plate (8) outside, and before bolt (10) is compressed, dust cover (9) and revolving is enclosed in fan bearing base (1) end.
Claims (3)
1. engine new fan shaft structure, comprise fan bearing base, spacer, rear dust cover, back-up ring, fan stuffing box bearing, fan pulley, straight pin, baffle plate, front dust cover, bolt, it is characterized in that described fan shaft part is by changing 6 mounting holes to fan bearing base (1) into by 4 original mounting holes, and after the rear and front end is sealed with dust cover (3), front dust cover (9), bearing changes fan stuffing box bearing (5) into.
2. according to a kind of engine new fan shaft structure claimed in claim 1, it is characterized in that fan stuffing box bearing (5) uses the straight pin bearing, dust cover (3) after installing between fan stuffing box bearing (5) and spacer (2).
