Abstract
The utility model relates to a novel rotary head for a cooling tower. The novel rotary head is composed of a screw cover, a rotary body which is connected with the screw cover, a tower-shaped rotary shaft which is arranged in the rotary body, a sealing pad and a pressing nut which are connected with the rotary shaft, and bearings which are arranged at both ends of the rotary shaft. The novel rotary head can prevent water from outwards soaking, and can ensure the concentricity of the two bearings. In addition, the utility model has the advantages of less abrasion loss, long service life and simple structure.
Description
The utility model relates to a kind of water seal rotary head of used for cooling tower.
Spring skeleton axle envelope is adopted in present rotary head more, can only unidirectionally leak to inner waterproofing, can not outwards prevent water saturates, as shown in Figure 2, two block bearings are installed in two upper and lower turning on 21,22 by being threaded respectively, and its concentricity is difficult to guarantee that error is bigger, therefore increased radial load and aggravated wearing and tearing, made shorten service life.And rotating shaft wherein is, and the centre is thick, the thin structure in two, makes the rotating shaft force-bearing situation unreasonable.
The purpose of this utility model is to avoid above-mentioned weak point among the background technology and provides a kind of two bearings are installed in the same turriform rotating shaft, the turriform rotating shaft is installed in the turning of integral body, sealing gasket in the rotating shaft simultaneously adopts Y profile shaft envelope to add O profile shaft seal structure, can guarantee the bearing concentricity, reduce error, reduce wear, increase the service life, waterproofly again outwards soak into the better novel rotary head of water resistance.
The purpose of this utility model realizes by following approach: blind nut connects turning of integral body, and the turriform rotating shaft is installed in integral body is turned, and sealing gasket is installed in the turriform rotating shaft and is pressed mother, turriform rotating shaft two ends connection bearing.
Novel rotary head of the present utility model, sealing gasket adopt Y profile shaft envelope to add the structure of O profile shaft envelope.
The utility model is compared background technology following advantage: can prevent that sealing outwards soaks into, strengthened sealing effectiveness, rotating shaft is turriform, stressed more reasonable, turn and overall structure, improve the running precision of rotary head greatly, and can guarantee the concentricity of bearing, reduce wear, increase the service life, and structure is simpler.
The middle in conjunction with the accompanying drawings embodiment of the utility model is described in further detail:
The novel rotary head schematic diagram of Fig. 1 (Figure of abstract);
Fig. 2 is existing rotary head structural representation.
As shown in Figure 1, novel rotary head of the present utility model, blind nut 1 connects integral body and turns 2, and integral body is turned and turriform rotating shafts 6 is installed in 2, sealing gasket 4 is installed in the turriform rotating shaft 6 and is pressed femalely 3, and bearing 5 is installed at turriform rotating shaft 6 two ends.Sealing sincere 4 adopts Y profile shaft envelope to add O profile shaft seal structure.
Claims (2)
1, a kind of novel rotary head, it comprises blind nut (1), is installed in the sealing gasket (4) in the rotating shaft (6) and presses female (3), and it is characterized in that: turn (2) that are connected with blind nut (1) are whole, turriform rotating shaft (6) is installed in turn (2) that are integral body, and bearing (5) is installed at rotating shaft (6) two ends.
2, novel rotary head according to claim 1 is characterized in that: the sealing gasket that is installed in the rotating shaft (6) adopts Y profile shaft envelope to add O profile shaft seal structure.
