Abstract
The utility model discloses a fan shaft part, wherein the front and rear ends of the fan shaft are respectively provided with front and rear dustproof covers,a clearance is reserved between the front and rear dustproof covers and a belt pulley, and the fan shaft part is positioned by a four-point contact bearing. The problems that the sticking of the fan shaft, falling apart of the bearing and the like are caused by dust entering and bearing grease lubricant loss and the breakdown of the fan shaft part bolts are caused by the rotation with the fan shaft part are solved. The design method of the fan shaft part can be applied to other fan shaft parts.
Description
Technical field
The utility model belongs to motor and water tank fan shaft parts.
Background technique
At present, in service at these type of fan shaft parts, thereby cause the bearing of fan shaft parts stuck owing to there is dust to enter in the fan shaft parts, or because the fan shaft parts are moving situations such as unlubricated dose of a period of time aft-fan spindle unit bearing causes that bearing falls apart, the result causes the original equilibrium forfeiture of fan, the axial motion quantitative change is big, decreases the ring water tank.
Summary of the invention
Of the present utility model day being provides 4 contact seal bearings of a kind of usefulness to solve lubrication problem, the rear and front end installs dust cover additional and solves the problem that dust enters, and solves behind the bearing long-play unlubricated fat and dust and enters and cause the stuck phenomenon of bearing to take place.Carry out improved novel fan shaft parts on the original structure basis.
Technical solution of the present utility model is such: a kind of fan shaft parts, dust cover, bearing, spacer, baffle plate, back-up ring, straight pin before and after comprising, it is characterized in that there is straight pin the fan shaft end, with preceding dust cover is arranged, the fan shaft rearward end has back dust cover, and is gapped between back dust cover, preceding dust cover external diameter and the belt pulley.
Dust cover, baffle plate before installing between fan shaft end and the double-screw bolt, straight pin passes baffle plate and puts into the fan shaft end, dust cover before the dress between baffle plate and the bolt.
Bearing four spot contact bearings are installed the back dust cover between the bearing and first spacer.
The utility model fan shaft parts have following beneficial effect:
1, prevents that dust from entering the fan shaft parts;
2, prevent to cause the fan stall because of fan shaft parts bearing is stuck;
3, prevent to break water tank after bearing from falling apart;
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is the utility model fan shaft parts sectional views.
1: the first spacer (1), back dust cover (2), bearing (3), second spacer (4), back-up ring (5), baffle plate (6), preceding dust cover (7), straight pin (8), gap (9), bolt (10), belt pulley (11), fan shaft (12) in conjunction with the accompanying drawings.
Embodiment
Most preferred embodiment of the present utility model is such, with reference to Fig. 1, shown in Figure 1, the utility model fan shaft parts, that described fan shaft parts adopt is sealed at both ends (among Fig. 1 behind the 2-before dust cover, the 7-dust cover), bearing changes 4 contact seal bearings into, and described fan shaft parts are avoided because of dust enters stuck that the fan shaft parts cause, simultaneously the bearing failure because of adopting four dot encapsulation bearings to avoid lubricating grease to run off and cause.
As shown in Figure 1, should leave gap (9) in the middle of back dust cover (2) in the dust cover (among Fig. 1 shown in 2,7) and fan shaft parts belt pulley (11) mating groove, before and after preventing dust cover with fan spindle unit belt pulley with changeing.Straight pin (8) (among Fig. 1 shown in 8) prevents that fan shaft parts bolt from rotating the phenomenons such as bolt fracture that cause with fan spindle unit belt pulley and taking place.Specifically: fan shaft (12) has preceding dust cover (7), back dust cover (2) with front end and back end between belt pulley (11) is connected, the corresponding positions of dust cover (7,2) is equipped with the preceding dust cover (7) of groove kiln dress, back dust cover (2) before and after the installation of belt pulley (11), when mounted between front and back dust cover (7,2) and the belt pulley (11) gapped (9).Straight pin (8) passes baffle plate (6) and is enclosed in fan shaft (2) front end, and bearing (3) is decorated contact bearing with four.First spacer (1) is installed in the step shaft shoulder of fan shaft (12), then adorn back dust cover (2) again, bearing (3), back-up ring (5), second spacer (4) belt pulley (11) inner chamber of packing into, belt pulley (11) suit is gone into fan shaft (12), load onto baffle plate (6) in fan shaft (12) end, straight pin (8) passes baffle plate (6) and is inserted in fan shaft (12) end, preceding dust cover (7) veneer is contained in baffle plate (6) outside, bolt (10) is compressed preceding dust cover (7) and revolves be enclosed in fan shaft (12) end.
Claims (3)
1. fan shaft parts, dust cover, bearing, spacer, baffle plate, back-up ring, straight pin before and after comprising, it is characterized in that there is straight pin (8) fan shaft (12) end, with preceding dust cover (7) is arranged, fan shaft (12) rearward end has back dust cover (2), between back dust cover (2), preceding dust cover (7) external diameter and the belt pulley (10) gapped (9).
2. according to the described fan shaft parts of claim 1, dust cover (7), baffle plate (6) before it is characterized in that installing between fan shaft (12) end and the double-screw bolt (10), straight pin (8) passes baffle plate (6) and puts into fan shaft (12) end, dust cover (7) before the dress between baffle plate (6) and the bolt (10).
3. according to the described fan shaft parts of claim 1, it is characterized in that bearing (3) uses four spot contact bearings, back dust cover (2) is installed between bearing (3) and first spacer (1).
