Description
Technical field
The utility model relates to a kind of bearing part for axial-flow pump, applies to belong to the bearing part field in the transmission device in the axial-flow pump unit.
Background technique
Transmission device in the axial-flow pump unit is that the pump group is steady, the Reliable guarantee of safe operation.The lubricating condition of transmission device middle (center) bearing affects the operation conditions of pump straight, so bearing need to have good lubricating condition.In existing axial-flow pump transmission device two bearings are arranged, namely bear the double-row radial ball bearing and the single direction thrust ball bearing of bearing axial force of radial force, what double-row radial ball bearing adopted is grease lubrication, and single direction thrust ball bearing is thin oil lubricant.Pump is in running, and along with bearing temperature raises, the flowability of lubricating grease strengthens, and is subjected to the effect of centrifugal force, and lubricating grease is easy to break away from double-row radial ball bearing.Double-row radial ball bearing is under the unlubricated state moves, long-play causes double-row radial ball bearing to damage.So the bearing part that is used for axial-flow pump of inventing a kind of better performances is very useful.
Summary of the invention
The purpose of this utility model is exactly for defects, and the bearing part that is used for axial-flow pump that a kind of lubrication effect is better, bearing capacity is strong, the life-span is long is provided.
The technical solution adopted in the utility model is: it comprises bearing support, bearing bracket stand, bearing cap and axle journal, bearing bracket stand and bearing cap are bolted, cover has selfaligning ball bearing and self-aligning thrust roller bearing on the described axle journal, selfaligning ball bearing and self-aligning thrust roller bearing are installed in bearing support and the bearing bracket stand, self-aligning thrust roller bearing has further improved the bearing capacity of axial force, be processed with square threaded form in the axle journal, gap location between axle journal bottom and the bearing support is provided with the oil sealing cylinder, prevent that lubricant oil is excessive, also be provided with oil drainage hole in the axle journal, oil drainage hole is communicated with the lubricant oil oil pocket, by guaranteeing the gap of oil sealing cylinder and axle journal, the square threaded form of axle journal promotes the lubricant oil in the oil sump through centrifugal force in when operation, and the oil drainage hole by axle journal enters selfaligning ball bearing, thereby plays the effect of lubricated selfaligning ball bearing.
Further, described bearing support is provided with oil ga(u)ge, cooling water intake and coolant outlet.Oil ga(u)ge is used for observing the oil level in the bearing support, need to determine whether make-up oil; Cooling water outlet and inlet, water-cooling tube further reduce bearing temperature mainly for delivery of cooling water.
Further, described bearing cap is provided with oil fill plug, and the bearing support bottom is provided with purge cock.Oil fill plug is used for replenishing the lubricant oil of cleaning, and purge cock is used for discharging the waste lubricating oil of periodic replacement.
The utlity model has simple in structure, reliable in function, practical characteristics, it has used in the axial-flow pump bearing part and has born the radial force selfaligning ball bearing, bears the self-aligning thrust roller bearing of axial force, has further improved the bearing capacity of axial force.Simultaneously, the utlity model has high lubricating effect, the characteristics of long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the utility model comprises bearing support 1, bearing bracket stand 2, bearing cap 3 and axle journal 4, bearing bracket stand 2 and bearing cap 3 are bolted, cover has selfaligning ball bearing 5 and self-aligning thrust roller bearing 6 on the axle journal 4, selfaligning ball bearing 5 and self-aligning thrust roller bearing 6 are installed in bearing support 1 and the bearing bracket stand 2, self-aligning thrust roller bearing 6 has further improved the bearing capacity of axial force, be processed with square threaded form 15 in the axle journal 4, gap location between axle journal 4 bottoms and the bearing support 1 is provided with oil sealing cylinder 7, prevent that lubricant oil is excessive, also be provided with oil drainage hole 16 in the axle journal 4, oil drainage hole 16 is communicated with lubricant oil oil pocket 17, by guaranteeing the gap of oil sealing cylinder 7 and axle journal 4, the square threaded form 15 of axle journal 4 promotes the lubricant oil in the oil sump through centrifugal force when operation, oil drainage hole 16 by axle journal 4 enters selfaligning ball bearing 5, thereby plays the effect of lubricated selfaligning ball bearing 5.Bearing support 1 is provided with oil ga(u)ge 8, cooling water intake 11 and coolant outlet 12.Oil ga(u)ge 8 is used for observing the oil level in the bearing support 1, need to determine whether make-up oil; Cooling water outlet and inlet 11,12, water-cooling tube further reduce bearing temperature mainly for delivery of cooling water.Bearing cap 3 is provided with oil fill plug 13, and bearing support 1 bottom is provided with purge cock 14.Oil fill plug 13 is used for replenishing the lubricant oil of cleaning, and purge cock 14 is used for discharging the waste lubricating oil of periodic replacement.Be provided with felt circle 10 between bearing cap 3 and the axle journal 4.Be respectively equipped with seal ring 9 between bearing cap 3 and the bearing bracket stand 2 and between bearing bracket stand 2 and the bearing support 1.Seal ring 9, felt circle 10 and oil sealing cylinder 7 are mainly used in the sealing of lubricant oil and prevent the leakage of lubricant oil.
After selfaligning ball bearing 5, self-aligning thrust roller bearing 6 are enclosed within on the axle journal 4, be installed in bearing support 1 and the bearing bracket stand 2, compress with bearing cap 3.By guaranteeing the gap of oil sealing cylinder 7 and axle journal 4, the square threaded form 15 of axle journal 4 promotes the lubricant oil in the oil sump through centrifugal force when operation, and the oil drainage hole 16 by axle journal 4 enters selfaligning ball bearing 5, thereby plays the effect of lubricated selfaligning ball bearing 5.
