Abstract
The utility model discloses a waterproof structure of a bearing, which comprises a drum shaft, a bearing box, a bearing gland bush, a stationary ring and a rotating ring, wherein the bearing box and the bearing gland bush are arranged on the drum shaft, the stationary ring is mounted on the bearing gland bush and coaxial with the bearing gland bush, the rotating ring is sheathed on the drum shaft, the rotating ring and the drum shaft are in non-clearance fit and can rotate along with the rotation of the drum shaft, a plurality of annular grooves or bulges which are coaxial with the stationary ring are arranged on the stationary ring, a plurality of annular bulges or grooves are correspondingly arranged on the rotating ring, and the stationary ring and the rotating ring are closely combined together through the annular grooves and the bulges. By adopting the waterproof structure of the bearing, water can be effectively prevented from entering into the bearing and the service life of the bearing is further prolonged.
Description
Technical field
The utility model relates to a kind of waterproof construction, relates in particular to a kind of bearing waterproof construction of belt Haug drainer.
Background technique
The belt Haug drainer is widely used in every field, and especially when carrying out water treatment, for the removings such as mud in the water, people generally can select to use the belt Haug drainer.Because the drum shaft two ends of belt Haug drainer cylinder all need to install bearing; in order to protect bearing better; be provided with bearings mounted bearing box and bearing gland at the drum shaft two ends; though can seal to prevent into water by seal ring etc. between bearing box and the bearing gland; but the gap between bearing gland and the drum shaft really can't seal; thereby cause waterproofing effect bad; therefore in running; water excessive or that splash still is easy to enter in the Haug drainer cylinder bearings at both ends; cause the bearing corrosion, shorten working life.
The model utility content
At the prior art above shortcomings, the purpose of this utility model just is to provide a kind of bearing waterproof construction, can prevent that effectively sealing enters in the bearing, thereby prolongs the life-span of bearing.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of bearing waterproof construction, comprise drum shaft, bearing box on the drum shaft and bearing gland, described bearing gland links to each other with bearing box by bolt, also comprise and be installed on the bearing gland and the stationary ring and the rotating ring that be sheathed on drum shaft on coaxial with bearing gland, no gap cooperates and can rotate with the rotation of drum shaft between described rotating ring and the drum shaft, on stationary ring, be provided with some coaxial with it annular grooves or projection, correspondence is provided with some annular protrusions or groove on rotating ring, and described stationary ring and rotating ring are closely linked by annular groove and projection.
Further, between groove and projection the gap in be filled with lubricating grease; When rotating ring is rotated and the frictional force between the stationary ring littler, waterproof further again.
Compared with prior art, advantage of the present utility model is: simple in structure, and can prevent that effectively sealing enters in the bearing, thereby prolong the life-span of bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, a kind of bearing waterproof construction of the utility model, comprise drum shaft 1, bearing box 2 on the drum shaft 1 and bearing gland 3, described bearing gland 3 links to each other with bearing box 2 by bolt, also comprise and being installed on the bearing gland 3 and with the coaxial stationary ring 4 of bearing gland 3 be sheathed on rotating ring 5 on the drum shaft 1, described stationary ring 4 can be fixing by bolt and bearing gland 3, convenient, no gap cooperates and can rotate with the rotation of drum shaft 1 between described rotating ring 5 and the drum shaft 1, thereby the gap between bearing gland 3 and the drum shaft 1 is blocked, avoid water to enter in the bearing, for further realizing no gap, rotating ring 5 and drum shaft 1 can be welded together.
On stationary ring 4, be provided with some coaxial with it annular grooves or projection, correspondence is provided with some annular protrusions or groove on rotating ring 5, described stationary ring 4 is closely linked by annular groove and projection with rotating ring 5, longitudinal profile after making stationary ring 4 and rotating ring 5 combining is maze-type structure, can farthest stop water to enter in the bearing.
Between groove and projection the gap in be filled with lubricating grease; When rotating ring 5 is rotated and the frictional force between the stationary ring 4 littler, waterproof further again.
The utility model is simple in structure, can prevent that effectively sealing enters in the bearing, thereby prolongs the life-span of bearing.
Claims (2)
1. bearing waterproof construction, comprise drum shaft (1), bearing box (2) on the drum shaft (1) and bearing gland (3), described bearing gland (3) links to each other with bearing box (2) by bolt, it is characterized in that: also comprise being installed in that bearing gland (3) is gone up and with the coaxial stationary ring (4) of bearing gland (3) be sheathed on rotating ring (5) on the drum shaft (1), no gap cooperates and can rotate with the rotation of drum shaft (1) between described rotating ring (5) and the drum shaft (1), on stationary ring (4), be provided with some coaxial with it annular grooves or projection, go up correspondence at rotating ring (5) and be provided with some annular protrusions or groove, described stationary ring (4) is closely linked by annular groove and projection with rotating ring (5).
2. a kind of bearing waterproof construction according to claim 1 is characterized in that: between groove and projection the gap in be filled with lubricating grease.
