Abstract
The present invention relates to a bearing device with a ball bearing. An inner bearing ring (5) of the bearing is arranged on a pipe ring (3) capable of freely rotating, and an outer bearing of the bearing is fixed in a supporting ring (13). each side covering ring (17, 18) of the bearing is matched with the inner bearing ring, covering rings (11, 12) are matched with the outer bearing ring and are used for water prevention and moisture prevention, and every two covering rings are matched mutually to form the labyrinth sealing. The covering rings which are matched with the fixed outer bearing ring (7) are provided with a filling opening (31) for lubricating oil and compressed air, a water outlet (22) and oil draining opening (36). Therefore, the bearing device can prevent splashed water from entering, and ensure that a continuous lubrication bearing generates the positive pressure in the device.
Description
The present invention relates to bearing means, particularly a kind of splashproof submerged bearing device with horizontal axis.
U. S. Patent NO.3,679,277 disclose a kind of bearing means that is used for motor reel, and it has a labyrinth seal and a slipper seal an axial side; Have only a slipper seal in another axial side, and be provided with a nozzle to the bearing lubricating oil spraying in this side, the lubricant oil that axially passes bearing can be discharged to outside the device through the lubricant oil discharge tube.Yet this bearing means will bear the bearing device as the pipe of spun casting mould of huge temperature variation and huge centrifugal force when not being suitable for the sort of work, because, for example when causing dimensional changes by the temperature great change, the opposite side that this device may cause relatively rotating part blocks, thereby works unsatisfactorily.
Produce the cylindrical shape die device free to rotate of plastic tube for utilizing the centrifugal moulding method; need large size bearing; this bearing should not produce noise as far as possible in order to protect environment; enter wherein but also must prevent to dabble; thereby can be from outside water heating and cooling pattern; such bearing does not also propose till now, and the bearing that the present invention proposes can satisfy existing requirement.
According to a kind of bearing means of the present invention, it comprises: an inner bearing collar; An outer collar bearing, it is provided with respect to described inner bearing collar spaced radial ground; Be used for connecting rotationally the supporting member of described inside and outside bearer ring, described supporting member is arranged between the described inside and outside bearer ring; The inboard first and second topped rings, they are connected the axial relative substantially both sides of described inner bearing collar, and they have the outer periphery; The outside first and second topped rings, they are connected the axial relative substantially both sides of described outer collar bearing, it is characterized in that, the described outside first and second topped rings have inner periphery, the described inner periphery of the described outside first topped ring and the described outer periphery of the described inboard first topped ring cooperatively interact, to constitute a labyrinth sealing with the axial inside opening of an axial outside opening and, the described inner periphery of the described outside second topped ring and the described outer periphery of the described inboard second topped ring cooperatively interact, to constitute the labyrinth sealing with the axial inside opening of an axial outside opening and; Be used for spraying the nozzle mechanism of pressurized gas and lubricant oil to described supporting member; Be used to drain the discharging mechanism of the lubricant oil of lubricated described supporting member, described nozzle mechanism and described discharging mechanism are located in the first and second topped rings of the described outside.
In a particularly advantageous embodiment, each forms two topped rings that connect with bearer ring free to rotate by interior ring and outer shroud, the edge of the close axle of each fixing topped ring is all by relevant abaxial those surrounded by edges of topped ring free to rotate, make it form two grooves that extend along ring betwixt, two each rings of fixing in the topped ring have a tap hole that leads to the downward sensing of a circular groove in the described circular groove.
Embodiments of the invention are described with reference to the accompanying drawings.
A unique accompanying drawing illustrates the vertical cross-section diagram of bearing means of the present invention.Big parts on schematic representation, have been saved on axis 10 both sides.This bearing means is as cylindrical shape pattern device free to rotate, accompanying drawing illustrates the part of this pattern, this part is by two tubular portions 1 that have flange 1a and 2a respectively and 2, constitutes with therebetween pipe ring 3, and two tubular portions 1 and 2 usefulness screws 4 are screwed on the pipe ring 3.The inner bearing collar 5 of ball bearing places on the pipe ring 3, and the ball of bearing is designated by numeral 6, and its outer collar bearing is designated by numeral 7.Outer collar bearing 7 is fixed on the fixed bearing ring 13 by two topped rings 11 and 12, and two topped rings 11 and 12 usefulness screws 14 fixedly secure on this supporting ring 13.Supporting ring 13 can be fixed on the bearing support with screw 15, and a screw 15 only is shown in the drawings.Be used for inner bearing collar 5 is fixed on pipe ring 3 with numbering 17 and 18 two topped rings that represent and that be screwed on the pipe ring 3 with screw 16.Topped ring 17 and 18 all is made up of interior ring and outer shroud respectively, and outer shroud represents that with 17a and 18a interior ring is represented with 17b and 18b.
Topped ring 17 so around the edge of topped ring 11 near axis, makes as drawings clear illustrates that away from the edge of axis these two edges or two fringe regions cooperate the formation labyrinths to seal.This sealing has axial outwardly open gap 19 and axial gap 20 to inner opening.Gap 19 is connected with circular groove 21, the outflow opening that has downward sensing bottom 22 of this circular groove 21, and by the water that gap 19 is immersed, the water that for example spatters into can spill out by this opening 22 again.
Because two topped rings 12 and 18 have and topped ring 11 and 17 identical formations, so there is no need it is elaborated.
At upper area, each the topped ring in two topped rings 11 and 12 is equipped with respectively and injects the mouth of pipe 31 and 32, and this mouth of pipe also has pressurized air connector 31a and 32a respectively.These two zones of injecting the inner of the mouth of pipe facing to ball 6 motions.On the one hand, this can the continuous lubrication ball and their supporting surface, on the other hand, can provide constant malleation, prevent that the moisture of outside from entering, when the environment following time of bearing working in the humidity of temperature variation, this point is a particular importance, otherwise this moment such danger can take place, when bearing part cools off, air in bearing also can cool off, thereby can to absorb other may be malaria.
Can also see that from accompanying drawing outside above-mentioned circular groove 21, two topped rings also form second annular groove that is designated by numeral 33.This circular groove oil exit pipe 34 is housed bottom, this oil exit pipe enters by ball bearing and two topped rings 11 and 17 spaces that form 35.The oil extraction connector 36 that oil supply and discharge is used is equipped with in its higher slightly bottom position in this space 35, and the oil exit pipe that connects the oil extraction connector can insert the oil tank of low level, perhaps connects an oil pump.Because the oil extraction connector is bottom a little higher than, thus the existence of oil sump guaranteed, thereby guaranteed lubricating bearings consistently.The pressurized air that flows through pressurized air connector 31a and 32a has prevented from owing to oily outflow or has been drawn out of to form vacuum, and this vacuum may make water or malaria enter into the inside of bearing.
Can obviously see the open-and-shut structure of bearing means of the present invention according to top narration: two topped rings are installed in the both sides at ball bearing, one of them topped ring is the monolithic shape, and another is made of two-part, the topped ring that matches with rigid bearing zone at an upper portion thereof is equipped with the injection mouth of pipe, and in lower region thereof outlet pipe and oil exit pipe is housed.
