Abstract
The utility model provides a non-pressure fluid lubrication machinery oil sealing device in order to overcom the deficiency that the non-pressure oil sealing device leaks oil and the repair cycle is short. A static seal sleeve is arranged on the end cover of a fluid lubrication machinery bearing housing, a movable seal sleeve is arranged at the position of the outer end surface of a bearing, an axle at the outer end of the bearing is enclosed by the static seal sleeve in the way of zero friction, and the static seal sleeve is enclosed by the movable seal sleeve in the way of zero friction. The utility model has the advantages of non-contact oil seal device, without oil leakage, without abrasion of oil seal elements, and the oil seal overhaul not required.
Description
1, technical field
The utility model belongs to the mechanical seal device field, is specifically related to the lubricated machinery oil seal arrangement of a kind of no pressured fluid.
2, background technique
At present the lubricated machinery oil seal arrangement of no pressured fluid commonly used mostly is contact seal or sets up the flinger ring type oil seal that combines in blower fan, water pump.All the time have friction between the parts of this type of oil sealing device, need periodical repair, consume human and material resources, especially maintenance or miscarriage will cause mechanical axis and bearing to burn out accident.
3, summary of the invention
In order to overcome existing no pressure oil seal arrangement easy oil leakage and short deficiency of repair cycle, the utility model proposes the lubricated machinery oil seal arrangement of a kind of no pressured fluid, this device is the non-contact type oil sealing device, do not have the wearing and tearing of oil seal, from but a kind of oil sealing device that need not to overhaul.
The purpose of this utility model reaches like this.
The technological scheme that the utility model adopted is a static seal gland to be set as interior cover on the end cap of liquid lubrication mechanical bearing case, place, exterior edge face at bearing is provided with a movable sealing sleeve as overcoat, static seal gland does not have the friction envelope with bearing outer end axle, and movable sealing sleeve does not then have static seal gland the friction envelope.
One end of movable sealing sleeve is a toroidal, and static seal gland is provided with the multistage concave-convex shape.
Movable sealing sleeve and bearing lock nuts are designed to one.
Static seal gland and movable sealing sleeve form the laminar screening to axle and take, and distance is not to have friction for placing restrictions between the two.
The oil of lubricating bearings by outer seal sleeve front end tapering part by the rotary centrifugal force effect, major part is thrown to fuel tank, the oil that is spattered on the inner seal sleeve relies on gravity at the concavo-convex paragraph oil sump tank of difference, lubricant oil is realized isolation with main shaft by inside and outside stuffing box gland, thereby reaches purpose oil-proof, sealing.
Adopt the utility model can realize that seal arrangement is oil-proof, do not need the oil sealing maintenance, reach the effect of saving human and material resources.
4, description of drawings
Fig. 1 no pressured fluid of the present utility model lubricates machinery oil seal arrangement embodiment cross-sectional view
5, embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
1 set screw among Fig. 1,2 static seal glands, 3 movable sealing sleeves, 4,5 end caps, 6 bearings, 7 bearing housings.
Embodiment 1
In Fig. 1, static seal gland 2 is connected with the end cap 5 usefulness set screws 1 of bearing housing 7, and with axle 4 envelopes of bearing 6 outer ends, static seal gland 2 and 4 gaps of axle reach with movable sealing sleeve 3 interior edge face gaps and are the condition of placing restrictions on so that friction not to take place.Movable sealing sleeve 3 is fixedlyed connected with bearing 6, with static seal gland 2 envelopes; Static seal gland 2 and end cap 5 inner side surfaces are adorned between stationary seal ring the gap not to be had friction and is the condition of placing restrictions on.One end of movable sealing sleeve 3 is a toroidal, and static seal gland 2 is provided with the multistage concave-convex shape.Static seal gland and movable sealing sleeve form the laminar screening to axle and take, and distance is not to have friction for placing restrictions between the two.Static seal gland 2 and movable sealing sleeve 3 all adopt metallic material to make.
Embodiment 2
General structure is with embodiment 1, and wherein stuffing box gland 3 is made into one with bearing lock nuts, in bearing 6 outer ends with being threaded and locking.Static seal gland 2 and movable sealing sleeve 3 all adopt macromolecular material to make.
The utility model mainly is applicable to the lubricated machinery oil seal arrangement of the no pressured fluid in blower fan or the water pump, also goes for similarly lubricated mechanical device.
Claims (3)
1, the lubricated machinery oil seal arrangement of a kind of no pressured fluid comprises bearing (6), bearing housing (7), end cap (5), it is characterized in that also comprising following content:
The end cap (5) of bearing housing (7) is provided with static seal gland (2), with axle (4) the nothing friction envelope of bearing (6) outer end; Place, exterior edge face at bearing (6) is provided with movable sealing sleeve (3), and static seal gland (2) is not had the friction envelope.
2. no pressured fluid according to claim 1 lubricates the machinery oil seal arrangement, it is characterized in that: an end of movable sealing sleeve (3) is a toroidal, and static seal gland (2) is provided with the multistage concave-convex shape.
