Abstract
The utility model provides a transparent cap sealing structure of a fan shaft, which has simple structure, low cost, and reliability of sealing. In the sealing structure, the fan shaft penetrates through a transparent cap fixed on a casing and is fixed on a clamping ring of the transparent cap; a felt in sealed contact with the fan shaft is arranged in the clamping ring; a spring is encircled on the fan shaft positioned between the transparent cap and the clamping ring; and a downward inclined passage is formed on the transparent cap.
Description
Technical field
The utility model relates to the saturating lid sealing configuration of blower fan axle.
Background technique
The saturating lid sealing configuration of existing blower fan axle, referring to Fig. 1, blower fan axle 1 passes and is fixed on the saturating lid 2 on the housing 9 and is fixed on the trim ring 5 that covers, between trim ring and saturating lid, be provided with the felt 3 that contacts with the blower fan shaft sealing, the blower fan axle is provided with the centrifugal dish 4 that gets rid of, and the centrifugal dish 4 that gets rid of is positioned at the Seal cage that covers front end.Its sealing principle: under the centrifugal rotation of getting rid of dish of lubricant oil through rotating, get rid of radially flying out of dish, prevent that a large amount of lubricant oil from flowing out from the gap between saturating lid and the blower fan axle vertically along centrifugal at arbor with the wind; Felt has also further played and has prevented that lubricant oil from flowing out the effect of trim ring vertically simultaneously.
Because centrifugal to get rid of dish bigger, be installed on the blower fan axle also inconveniently, trouble is installed.Simultaneously, the sealing effect of above-mentioned sealing configuration is bad.
The model utility content
The purpose of this utility model provides a kind of saturating lid sealing configuration of simple in structure, with low cost, reliable sealing blower fan axle.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the saturating lid sealing configuration of blower fan axle, the blower fan axle passes and is fixed on the saturating lid on the housing and is fixed on the trim ring that covers, the felt that contacts with the blower fan shaft sealing is set in the trim ring, on the blower fan axle between saturating lid and the trim ring, be surrounded with spring, covering the passage that has under oblique thoroughly.
The beneficial effects of the utility model: be looped around the leakage vertically that spring on the blower fan axle has stoped lubricant oil, make lubricant oil splash in the cavity between lid and the trim ring.Have oblique passage down owing to cover thoroughly, the lubricant oil in the cavity is promptly along in this passage inflow Seal cage.Felt has also further played and has prevented that lubricant oil from flowing out trim ring vertically.
Above-mentioned sealing configuration, spring are joined end to end by helical spring and form.
Description of drawings
Fig. 1 is the schematic representation of the saturating lid sealing configuration of existing blower fan axle.
Fig. 2 is the schematic representation of the saturating lid sealing configuration of blower fan axle of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Referring to the saturating lid sealing configuration of blower fan axle shown in Figure 2, blower fan axle 1 passes and is fixed on the saturating lid 2 on the housing 9 and is fixed on the trim ring 5 that covers, and the felt 3 that contacts with the blower fan shaft sealing is set in the trim ring.Be surrounded with spring 4 on the blower fan axle between saturating lid and the trim ring, spring 4 is formed by connecting from beginning to end by spiral tension spring, spring 4 under the effect of elastic force, hold tightly the blower fan axle circumferentially.Covering the passage 6 that has under oblique thoroughly.
Be looped around the leakage vertically that spring 4 on the blower fan axle has stoped lubricant oil, make lubricant oil splash in the cavity 7 between lid and the trim ring.Have oblique passage down owing to cover thoroughly, the lubricant oil in the cavity 7 are promptly along in this passage inflow Seal cage 8.Felt has also further played and has prevented that lubricant oil from flowing out trim ring vertically.
Claims (2)
1. the saturating lid sealing configuration of blower fan axle, the blower fan axle passes and is fixed on the saturating lid on the housing and is fixed on the trim ring that covers, the felt that contacts with the blower fan shaft sealing is set in the trim ring, it is characterized in that: on the blower fan axle between saturating lid and the trim ring, be surrounded with spring, covering the passage that has under oblique thoroughly.
2. sealing configuration as claimed in claim 1 is characterized in that: spring is joined end to end by helical spring and forms.
