Description
[technical field]
The present invention relates to the support device technical field of pump, particularly a kind of vertical pump double-positioning bearing support device with rotatable parts.
[background technique]
Pump for various vertical installations, the supporting way of rotatable parts is varied, some adopts slide thrust bearing, some adopts thrust roller bearing, some or structure more complicated, the pump operation vibration is bigger, and axially locating with radially being difficult to of rotatable parts makes pump operation not steady, unreliable.
[summary of the invention]
Task of the present invention provides a kind of double-positioning bearing support device, and it has mainly solved the technical problem of following three aspects: the one, and for the vertical structure pump, axial and radially the support and the location of rotatable parts; The 2nd, the pump rotor axial position can be adjusted up and down as required; The 3rd, design good bearing lubrication system, guarantee the bearing good lubricating effect.
For achieving the above object, the present invention proposes a kind of double-positioning bearing support device, comprise bearing support, oil level indicator, self-aligning thrust roller bearing, bearing bracket, bearing gland, deep groove ball bearing, axle journal, transmission shaft, adjusting nut, permanent position lubricating cup, the oil sealing bucket, it is characterized in that bearing support 1 upper end snail ties connects bearing bracket 4, the bearing support lower end snail ties and connects oil sealing bucket 13, between bearing support 1 and the axle journal 7 self-aligning thrust roller bearing 3 is housed, between bearing bracket 4 and the axle journal 7 deep groove ball bearing 6 is housed, bearing bracket 4 upper end snails tie and connect bearing gland 5, axle journal 7 is by the key transmission shaft 8 that is connected, axle journal 7 upper ends connect adjusting nut 9, and adjusting nut 9 is contained on the transmission shaft 8; Bearing support 1 internal cavities is irritated lubricant oil, and permanent position lubricating cup 12 and oil level indicator 2 are housed on the bearing support 1, and oil level indicator is communicated with the bearing support internal cavities, and the oil outlet of lubricating cup is the slope mouth; Be equipped with trapezoidal thread groove 15 on the inner round wall of axle journal 7 lower ends, have on the axle journal 7 be connected with the trapezoidal thread groove radially get rid of oilhole 16; Lip type outside framework oil seal 10 is equipped with in bearing gland 5 intermediate portions, has exhaust port on the bearing gland 5, and venting plug 11 is housed in the exhaust port.
The present invention compared with prior art, novel structure, easy to use, the axially locating and the radial location of whole rotatable parts both can have been guaranteed, make pump operation steadily reliable, can also realize the adjustment (regulating as required) of the upper-lower position of transmission shaft, and bearing oil system perfecting of the present invention, can guarantee the good lubrication of bearing, be worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Referring to Fig. 1,1 is that bearing support, 2 is that oil level indicator, 3 is that self-aligning thrust roller bearing, 4 is that bearing bracket, 5 is that bearing gland, 6 is that deep groove ball bearing, 7 is that axle journal, 8 is that transmission shaft, 9 is that adjusting nut, 10 is that lip type outside framework oil seal, 11 is that venting plug, 12 is that a perseverance lubricating cup, 13 is that oil sealing bucket, 14 is that plug screw, 15 is that trapezoidal thread groove, 16 is for radially getting rid of oilhole.
[specific embodiment]
Referring to Fig. 1, be the instantiation that double-positioning bearing support device of the present invention is applied in vertical long shaft pump.The whole rotor part weight of major axis pump and operation axial force are born by duplex bearing bracket system of the present invention, and the synergy of duplex bearing realizes the axial and radial location of rotatable parts.
Concrete enforcement is as follows: bearing support 1 upper end bolt connection bearing support 4, the outer ring of self-aligning thrust roller bearing 3 and rolling element are installed on the bearing support 1, the inner ring of self-aligning thrust roller bearing is installed on the axle journal 7, deep groove ball bearing 6 also is assembled on axle journal 7 and the bearing bracket 4, then journal element is assembled to bearing support in the lump.After bearing gland 5 puts in place along axle journal 7 mounted on surface, bearing gland 5 adopts bolt to be connected bearing bracket 4 upper ends, lip type outside framework oil seal 10 is assembled to the intermediate portion of bearing gland 5 and matches with axle journal 7, venting plug 11 is inserted in the exhaust port on the bearing gland.On transmission shaft 8, adorn driving key, the keyway of axle journal is aimed at driving key, transmission shaft 8 is assembled on the axle journal 7, and the adjusting nut 9 of screwing on transmission shaft 8 is adjusted correct position, to adjust nut with screw is fixed on the axle journal 7, oil sealing bucket 13 is fixed by bolts to the lower end of bearing support 1, and the bearing support 1 inner cavity that forms sealing installs permanent position lubricating cup 12 and oil level indicator 2 on the bearing support 1, the plug screw 14 of screwing on, bearing support 1 internal cavities are irritated and are gone up lubricant oil.In addition, be equipped with trapezoidal thread groove 15 on the inner round wall of axle journal 7 lower ends, have on the axle journal 7 be connected with the trapezoidal thread groove radially get rid of oilhole 16.
The axial force that acts on the transmission shaft is delivered to adjusting nut by screw thread on the axle, and adjusting nut acts on the axle journal, and axle journal is by self-aligning thrust roller bearing and deep groove ball bearing location and bear load.The duplex bearing synergy realizes the axial and radial location of rotation axis system, and bracket system both can bear thrust load and radial load.By adjusting nut 9, can adjust the axial position of transmission shaft up and down.
By the key transmitting torque, axle journal rotates with transmission shaft, and bearing support 1 is formed lubricating oil bath with oil sealing bucket 13, and the lubricant oil of oil sump rises along the trapezoidal thread groove, throws away through radially getting rid of oilhole, is sprayed onto deep groove ball bearing 6 rolling element surfaces, and upper bearing (metal) is realized splash lubrication.The duplex bearing bracket system is provided with permanent position lubricating cup 12, and oil level indicator is communicated with the bearing lubrication oil sump, and the oil outlet of lubricating cup is designed to the inclined-plane, when bearing lubrication oil sump oil level descended, the hydraulic fluid port inclined-plane of lubricating cup exposed, and air enters lubricating cup, oil in the lubricating cup falls, and when lubricant oil floods the hydraulic fluid port inclined-plane again, forms vacuum in the lubricating cup, lubricant oil does not fall down again, like this, permanent position lubricating cup 12 can be realized automatic repairing, and, as long as in the lubricating cup oil is arranged, but the oil level in retainer shaft bearing lubrication oil pond is constant.Can also see the oil level of looking into the bearing lubrication oil sump, make-up oil at any time by oil level indicator.Guarantee the bearing good lubricating effect, improve the safety reliability of pump operation.
