Abstract
The utility model discloses an air curtain sealed bearing block, comprising a bearing block case (1) and a gland (2). The inner cavity (3) of the bearing block case (1) is provided with a transmission shaft (4) and a bearing (5); the bearing (5) is supported on the transmission shaft (4); a reinforced seal (6) is arranged between the transmission shaft (4) and the bearing block case (1). The diversity is that a through-hole (7) is arranged on the bearing block case (1); one end of the through-hole (7) is communicated with the inner cavity (3) of the bearing block case (1), and the other end of the through-hole (7) is connected with an externally connected pipeline (8). The utility model which can effectively prevent the ash from entering the bearing has good sealing effect and long service life.
Description
Technical field
The utility model relates to a kind of engineering transmission component, specifically relates to a kind of bearing support that is used for the elevator drum transmission.
Background technique
The bearing support that is used for noria lower cylinder bearing at present, the one, adopt the wool felt sealing and dustproof, the back is easy to wear because wool felt is subjected to rubbing, and dust easily enters bearing, and sealing effect is poor, and working life is short; The 2nd, adopt outside framework oil seal to seal, because the noria lower cylinder is interrupted the influence of uneven impact load, easily causes the one-sided wearing and tearing of outside framework oil seal, even cause damage of bearings.
Summary of the invention
The purpose of this utility model is to provide a kind of Air Curtain Sealed Bearing Base more rational in infrastructure, and it can prevent effectively that dust from entering bearing, good sealing effect, long service life.
The utility model is to solve the problems of the technologies described above to realize by following technical proposal, a kind of Air Curtain Sealed Bearing Base, comprise bearing support shell, gland, be equipped with transmission shaft and bearing in the inner chamber of above-mentioned bearing support shell, above-mentioned bearing is supported on the transmission shaft, is equipped with outside framework oil seal between above-mentioned transmission shaft and bearing support shell, difference is, be equipped with through hole on the above-mentioned bearing support shell, above-mentioned through hole one end communicates with the inner chamber of above-mentioned bearing support shell, and the other end links to each other with external pipe.
Above-mentioned through hole is between above-mentioned outside framework oil seal and above-mentioned bearing.
Above-mentioned external pipe is a flexible pipe, the influence of bearing support vibrations when making external pipe not be subjected to work.
Air Curtain Sealed Bearing Base of the present utility model has following advantage compared with prior art:
This bearing support adopts and feed pressurized air in the bearing support inner chamber, forms air curtain in the bearing side, has stoped the dust that enters the bearing support inner chamber on a small quantity to enter bearing.Simultaneously, because compressed-air actuated feeding makes the inside and outside pressure difference that forms of bearing, dust is difficult for entering in the bearing support inner chamber, can prevent effectively that dust from entering bearing, and Sealing is not subjected to the influence of uneven impact load, good sealing effect, long service life.

Fig. 1 is the structural representation of the utility model Air Curtain Sealed Bearing Base;
Embodiment
Embodiment
As shown in Figure 1, a kind of Air Curtain Sealed Bearing Base, comprise bearing support shell 1, gland 2, be equipped with transmission shaft 4 and bearing 5 in the inner chamber 3 of above-mentioned bearing support shell 1, above-mentioned bearing 5 is supported on the transmission shaft 4,1 on above-mentioned transmission shaft 4 and bearing support shell are equipped with outside framework oil seal 6, difference is, be equipped with through hole 7 on the above-mentioned bearing support shell 1, above-mentioned through hole 7 one ends communicate with the inner chamber 3 of above-mentioned bearing support shell 1, and the other end links to each other with external pipe 8, and above-mentioned through hole 7 is between above-mentioned outside framework oil seal 6 and above-mentioned bearing 5, above-mentioned external pipe 8 is a flexible pipe, the influence of bearing support vibrations when making external pipe not be subjected to work.
When work, in the inner chamber 3 of bearing support 1, feed pressurized air by external pipe 8, through hole 7, at this moment and since compression empty feeding, stoped the dust that enters the bearing support inner chamber on a small quantity to enter bearing; Make the inside and outside pressure difference that forms of bearing simultaneously, dust is difficult for entering in the bearing support inner chamber, prevents that effectively dust from entering bearing.
Claims (3)
