Abstract
The utility model provides a bearing protected internal fan generator, which comprises a bearing baffle plate, a belt pulley and a generator body. The bearing baffle plates are in convex shapes, the inner ring of each bearing baffle plate close to a bearing seal ring is bent outwards, a concave protection groove is arranged on the belt pulley, a convex ring is disposed on the end face of a front end cover of the generator body close to the belt pulley, and the convex ring is clamped inside the concave groove of the belt pulley. The bearing protected internal fan generator is mainly applied to internal fan generator driving ends, water or dust entering the bearing is reduced greatly by the aid of the labyrinth type bearing protection structure, so that original failure rate 8000ppm of the generator bearing is reduced to 2000ppm after the labyrinth type protection structure is added, and generator failure rate is reduced greatly.
Description
Technical field
The utility model patent relates to a kind of automobile and protects with internal fan alternating current generator protection, especially drive end bearing.
Background technology
In the prior art, most of automobile does not adopt dustproof construction with internal fan alternating current generator drive end bearing, and in many areas, the environment for use of generator is comparatively abominable, dust, water etc. easily enter in the bearing, cause the grease sintering, thereby cause bearing early failure failure rate higher.
Summary of the invention
For anti-sealing, dust etc. enter in the bearing, reduce the technical barrier of bearing early failure failure rate, the utility model proposes a kind of protection internal fan generator.
The technical scheme of the utility model patent is: a kind of protection internal fan generator, comprise bearing baffle, belt pulley, generator body, it is characterized in that: bearing baffle is a convex, the close bearing sealed ring inner ring place of bearing baffle is bending outward, belt pulley is provided with the spill protective trough, generator body front end housing is provided with convex ring near the belt pulley end face, and annulus is connected in the belt pulley Baltimore groove.
The utility model is a convex with the baffle design of rigid bearing, when water or dust etc. are entered motor internal especially near the bearing time by the air channel, because the close bearing sealed ring inner ring place of bearing baffle is bending outward, water or dust are partly stayed this bending part, major part flows to and is thrown out of after axle is gone up, and does not almost have water or dust etc. to enter in the bearing from the bearing left side; On belt pulley, increase a spill protective trough, stretch out a convex ring at front end of shield near the belt pulley end face, this annulus puts in the belt pulley Baltimore groove, in convex ring and the belt pulley protective trough, the gap of external diameter and axial direction is all less, when there are water or dust in generator drive end outside, because motor has increased above-mentioned labyrinth type safeguard structure, water or dust have only sub-fraction to enter between end cap annulus outer ring and the belt pulley protective trough, the water or the dust overwhelming majority that enter in the motor are thrown out of along the gap, have only few part to stay in the end play of annulus and belt pulley protective trough, and it is longer to arrive bearing sealed ring place distance herein, water or dust can't enter in the drive end bearing substantially, have therefore improved the bearing protection ability greatly.
The utility model patent is mainly used in internal fan generator drive end, labyrinth type protection structure, having reduced water or dust largely enters in the bearing, the failure rate that makes dynamo bearing drops to 2000ppm by the 8000ppm that increases before the labyrinth type safeguard structure, greatly reduces the generator failure rate.

Fig. 1 is the utility model structural representation.
Embodiment
A kind of as shown in Figure 1 protection internal fan generator, comprise bearing baffle 1, belt pulley 2, generator body 3, bearing baffle 1 is a convex, bearing baffle 1 close bearing sealed ring 4 inner ring places are bendings outward, belt pulley 2 is provided with spill protective trough 5, generator body 3 front end housings are provided with convex ring 6 near belt pulley 2 end faces, and annulus 6 is connected in belt pulley 2 Baltimore grooves.
The utility model is a convex with the baffle design of rigid bearing, when water or dust etc. are entered motor internal especially near the bearing time by the air channel, because the close bearing sealed ring inner ring place of bearing baffle is bending outward, water or dust are partly stayed this bending part, major part flows to and is thrown out of after axle is gone up, and does not almost have water or dust etc. to enter in the bearing from the bearing left side; On belt pulley, increase a spill protective trough, stretch out a convex ring at front end of shield near the belt pulley end face, this annulus puts in the belt pulley Baltimore groove, in convex ring and the belt pulley protective trough, the gap of external diameter and axial direction is all less, when there are water or dust in generator drive end outside, because motor has increased above-mentioned labyrinth type safeguard structure, water or dust have only sub-fraction to enter between end cap annulus outer ring and the belt pulley protective trough, the water or the dust overwhelming majority that enter in the motor are thrown out of along the gap, have only few part to stay in the end play of annulus and belt pulley protective trough, and it is longer to arrive bearing sealed ring place distance herein, water or dust can't enter in the drive end bearing substantially, have therefore improved the bearing protection ability greatly.
The utility model patent is mainly used in internal fan generator drive end, labyrinth type protection structure, having reduced water or dust largely enters in the bearing, the failure rate that makes dynamo bearing drops to 2000ppm by the 8000ppm that increases before the labyrinth type safeguard structure, greatly reduces the generator failure rate.
