Abstract
The utility model discloses an end cover of a bearing box of a fan, oil scraping tanks are arranged in the end cover, and an oil discharge tank communicated with the oil scraping tanks is axially arranged in the end cover. In the utility model, the oil discharge tank is arranged at the oil scraping tanks, the oil in the oil scraping tank is returned into the bearing box through the oil discharge tanks, so that the oil leakage phenomenon of the sealed end cover can be eradicated, the sealability is good, the oil lack phenomenon of an oil tank, caused by the oil leakage, can be avoided, and the lubrication effect of a bearing can be improved.
Description
Technical field
The utility model relates to a kind of fan bearing case end cap.
Background technique
Generally, blower fan gap bridge end cap adopts traditional sealing means, its structure is that bearing (ball) cover adds little gland, and big end cap provides axial pre tightening force in order to the fastener shaft bearing outer-ring to bearing outer ring, simultaneously bearing housing lubricant oil is sealed, be again the fixing base of little end cap, little end cap is used to seal the radial clearance of transmission shaft, interior dabbing felt seal material, along with wearing out of equipment, its sealability is bad have been spilt day by day cruelly.Show as the leakage of oil of bearing (ball) cover place, oil impregnate, the continuous loss of lubricant oil pollutes the environment on the one hand; Can cause the generation of lubricated oil starvation risk on the other hand, influence the normal operation of equipment.
The model utility content
The purpose of this utility model provides a kind of fan bearing case end cap of good seal performance.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fan bearing case end cap is provided with wiper groove in the end cap, in axial direction be provided with the oil groove that unloads that is communicated with wiper groove in the end cap.
Described wiper groove is at least two.
The utility model adopts the structural design of unloading oil groove in the setting of wiper groove place, have the following advantages: 1. the oil in the wiper groove returns bearing housing by unloading oil groove, can stop the end cover oil leakage phenomenon, good seal performance, avoid leakage of oil and produce the fuel tank petrol starvation, improved the lubrication effect of bearing; 2. effectively guarantee the bearing good lubrication that runs up, avoided the generation of bearing locking phenomenon, stopped device security hidden danger, guaranteed the normal operation of equipment; 3. when the routine check bearing, be convenient to the dismounting of bearing (ball) cover, reduce labor intensity, increase work efficiency; 4. need not to increase sealing material, avoid fretting wear generation heat between stuffing box packing and the axle, make the sealing material carbonization, reduce pollution oil; 5. the facility environment sanitation and hygiene have been guaranteed.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1;
Erection drawing when Fig. 3 is the utility model use.
Embodiment
As shown in Figure 1 and Figure 2, a kind of fan bearing case end cap 1 is provided with wiper groove 2 in the end cap 1, in axial direction be provided with in the end cap 1 be communicated with wiper groove 2 unload oil groove 3, described wiper groove 2 is three, is communicated with by unloading oil groove 3 between the wiper groove 2.
As shown in Figure 3, during use, end cap 1 passes transmission shaft 4 and is installed on the bearing housing, be set with carbon steel flinger ring 5 on the transmission shaft 4, play elementary seal action, the oil that wiper groove 2 is collected is back to bearing housing by unloading oil groove 3, need not to increase sealing material and little gland and can realize sealing, good sealing effect.
Claims (2)
1. a fan bearing case end cap is provided with wiper groove in the end cap, it is characterized in that, in axial direction is provided with the oil groove that unloads that is communicated with wiper groove in the end cap.
2. fan bearing case end cap as claimed in claim 1 is characterized in that described wiper groove is at least two.
