Abstract
The utility model relates to a bearing gland for a diving sewage drainage pump, in particular to a structure improvement to a bearing gland, which comprises a bearing gland and a shaft hole, and is characterized in that the upper end of the bearing gland is provided with a boss, a through hole of the boss is connected with the shaft hole of the bearing gland, and the inner wall of the through hole of the boss is processed with labyrinth sealing slots. The bearing gland for the diving sewage drainage pump is characterized in that the slot width of the labyrinth sealing slots is 4mm, the depth is 2,5mm, the space between the labyrinth sealing slots is 4mm, and a gap between the through hole and a shaft is 0.5mm. The bearing gland for the diving sewage drainage pump has the advantages that the labyrinth sealing slots increase the resistance in the leakage flow of lubricating grease, when the resistance is big enough, the lubricating grease can not leak. Because the viscosity of the lubricating grease is bigger, the resistance when leaking is bigger, when the number of the labyrinth sealing slots is 2-3, and the lubricating grease can be prevented from leaking. The sealing is suitable for high-speed sealing, does not have friction, and has less power dissipation.
Description
Technical field
The utility model relates to a kind of bearing gland that is used for proof submersible sand discharging pump, particularly to the improvement of bearing gland structure.
Background technique
The bearing of proof submersible sand discharging pump is placed in the connecting base, and the effect of bearing gland is to push down bearing, by screw bearing gland and connecting base is linked together.Lubricating grease is housed in the bearing, and bearing in use can frictional heat, and it is thinning to cause lubricating grease to be heated, and under high speed rotating, lubricating grease will be thrown out of along the gap between axle and the bearing gland.
Summary of the invention
The purpose of this utility model is to eliminate the leakage of lubricating grease, and a kind of novel improved bearing gland structure is provided.The utility model designs a kind of novel sealing function bearing gland that has, comprise bearing gland, axis hole, it is characterized in that: in the upper end of bearing gland one boss is arranged, join, on the through-hole wall of boss, be processed with the labyrinth seal groove at the through hole of boss and the axis hole of bearing gland.It is characterized in that: the groove width 4mm of labyrinth seal groove, dark 2.5mm is spaced apart 4mm between the labyrinth seal groove, and the gap between through hole and the axle is 0.5mm.The utility model has the advantages that the labyrinth seal groove increases the resistance of lubricating grease in leakage flow, when resistance was enough big, lubricating grease just can not leak.Because lubricating grease viscosity is bigger, resistance is bigger during leakage, and the quantity of labyrinth seal groove just can stop lubricating grease to leak at 2 to 3.This sealing is applicable to sealing at a high speed, and does not have friction, and power consumption is few.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing one is the original structure schematic representation; Accompanying drawing two is the utility model schematic representation; Accompanying drawing three is use principle figure.Among the figure, 1 is casing, and 2 is axle, and 3 is bearing gland, and 4 is screw, and 5 is bearing, and 6 is connecting base, and 7 are mechanical seal.8 is boss, and 9 is axis hole, and 10 are the labyrinth seal groove.
Embodiment
Comprise bearing gland, axis hole among Fig. 2,3, it is characterized in that: in the upper end of bearing gland one boss is arranged, join, on the through-hole wall of boss, be processed with the labyrinth seal groove at the through hole of boss and the axis hole of bearing gland.It is characterized in that: the groove width 4mm of labyrinth seal groove, dark 2.5mm is spaced apart 4mm between the labyrinth seal groove, and the gap between through hole and the axle is 0.5mm.These labyrinth seal grooves and axle have formed " straight-through shape labyrinth ", and its effect is to increase the resistance of lubricating grease in leakage flow, and when resistance was enough big, lubricating grease just can not leak.Because lubricating grease viscosity is bigger, resistance is bigger during leakage, and the quantity of labyrinth seal groove just can stop lubricating grease to leak at 2 to 3.This sealing is applicable to sealing at a high speed, and does not have friction, and power consumption is few.
Claims (2)
1. one kind novel has a sealing function bearing gland, comprises bearing gland, axis hole, it is characterized in that: in the upper end of bearing gland one boss is arranged, join at the through hole of boss and the axis hole of bearing gland, be processed with the labyrinth seal groove on the through-hole wall of boss.
2. by the described a kind of novel sealing function bearing gland that has of claim 1, it is characterized in that: the groove width 4mm of labyrinth seal groove, dark 2.5mm is spaced apart 4mm between the labyrinth seal groove, and the gap between through hole and the axle is 0.5mm.
