Abstract
The utility model relates to a kind of high power density bearing of motor sealing structure, it mainly by: exterior seal ring, bearing internal external lid, lubricating cup, oil catcher, end cap, axis, inner seal ring, disc, gasket, ventilation hole etc. are constituted.Bearing cover is mounted on end cap, exterior seal ring interference hot jacket is on axis, bent line structure is formed with bearing cover, disc is mounted among inner seal ring and bearing, lubricating cup is mounted on bearing cover upper end, oil catcher is mounted on the lower end of bearing cover, and gasket is separately mounted between bearing cover and end cap, internal bearing cover and end cap, and multiple ventilation holes are provided on end cap.The product is using bent line structure design, there is gap for divulging information between internal bearing cover and inner seal ring, bearing cover and exterior seal ring, not only can be with cooling bearing, but also storing lubricating grease can be played the role of, reduce frictional dissipation and bearing heat, mechanical loss is small, sealing performance is high, and high lubricating effect is non-maintaining, low noise improves motor own efficiency.
Description
Technical field
The utility model relates to a kind of high power density bearing of motor sealing structures.
Background technique
Currently, bearing of motor sealing structure used in oil drilling platform mostly use greatly end cap, inner cover, bearing, outer cover,
Sealing ring is sealed, and sealing structure does not seal Qu Lu, is influenced bearing heat dissipation, is dissipated on the motor of the big torque of high power density
Thermal effect is poor, is difficult to play and had not only sealed but also the effect of ventilating and cooling.
Summary of the invention
The purpose of the utility model is to overcome disadvantages mentioned above, provide a kind of high power density bearing of motor sealing knot
Structure, it mainly solves bearing of motor sealing structure used in oil drilling platform and mostly uses end cap, inner cover, bearing, outer greatly
Lid, sealing ring are sealed, and sealing structure does not seal Qu Lu, bearing heat dissipation are influenced, in the motor of the big torque of high power density
Upper heat dissipation effect is poor, is difficult to play and had not only sealed but also the problems such as the effect of ventilating and cooling.The purpose of this utility model is realized in
, a kind of high power density bearing of motor sealing structure is by exterior seal ring, bearing cover, bolt, washer, lubricating cup, oil-collecting
Device, gasket, end cap, bearing, internal bearing cover, axis, inner seal ring, disc, ventilation hole are constituted.Bearing cover by bolt,
Washer is mounted on end cap, and exterior seal ring interference hot jacket forms bent line structure on axis, with bearing cover, and disc is mounted on interior
Among sealing ring and bearing, for positioning bearing, lubricating cup is mounted on bearing cover upper end, and oil catcher is mounted under bearing cover
End, gasket are separately mounted between bearing cover and end cap, internal bearing cover and end cap, and multiple ventilation holes are provided on end cap.It should
Product structure is simple, and rationally, it is using bent line structure design, internal bearing cover and inner seal ring, bearing cover and external seal for design
Have gap between circle for divulging information, it can cooling bearing, and storing lubricating grease can be played the role of, reduce frictional dissipation and
Bearing heat, mechanical loss is small, and sealing performance is high, and high lubricating effect is non-maintaining, low noise, improves motor own efficiency,
Performance safety is reliable, extends the service life of motor, is particularly suitable for using on drilling platforms at sea.
Detailed description of the invention:
Attached drawing 1 is a kind of schematic diagram of high power density bearing of motor sealing structure of the utility model.
1-exterior seal ring 2-bearing cover, 3-bolt, 4-washer, 5-lubricating cup
6-oil catcher 7-gasket, 8-end cap, 9-bearing, 10-internal bearing covers
11-axis 12-inner seal ring, 13-disc, 14-ventilation holes
Specific embodiment: the most preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings, a kind of high power are close
Spend bearing of motor sealing structure by: exterior seal ring 1, bearing cover 2, bolt 3, washer 4, lubricating cup 5, oil catcher 6, gasket 7,
End cap 8, bearing 9, internal bearing cover 10, axis 11, inner seal ring 12, disc 13, ventilation hole 14 are constituted.Bearing cover 2 passes through spiral shell
Bolt 3, washer 4 are mounted on end cap 8, and 1 interference hot jacket of exterior seal ring forms bent line structure with bearing cover 2, get rid of oil on axis 11
Disk 13 is mounted among inner seal ring 12 and bearing 9, and for positioning bearing 9, lubricating cup 5 is mounted on 2 upper end of bearing cover, oil catcher
6 are mounted on the lower end of bearing cover 2, gasket 7 be separately mounted to bearing cover 2 and end cap 8, internal bearing cover 10 and end cap 8 it
Between, multiple ventilation holes 14 are provided on end cap 8.
Working principle, bearing 9 pass through between inner seal ring 12, the positioning of disc 13, inner seal ring 12 and internal bearing cover 10
And bearing cover 2 and exterior seal ring 1 have Qu Lu to communicate, wind can be by bent road cooling bearing 9, and lubricating grease is without spilling,
Even if bearing the wind pressure of exterior blower 3.1MPa inside motor, bearing grease will not still leak outside when operating.
