Abstract
The utility model discloses a bearing gland on a bearing box of a clean water pump, comprising a bearing gland, the internal side wall of the bearing gland is provided with an annular framework oil seal, an annular groove is disposed between the framework of the annular framework oil seal and a rubber layer, a spring is provided in the annular groove, and an oil seal dismounting hole is disposed between the annular framework oil seal and the external side wall of the bearing gland. The bearing gland in the utility model is advantageous in that, improved structure is simple and practical, the framework oil seal is adopted to seal, seal effect is good, no oil leakage phenomenon is provided, and natural damage is not easily generated, therefore, no-leakage fault time is greatly prolonged.
Description
Technical field
The utility model mainly is the bearing gland on a kind of clean waterpump bearing housing.
Background technique
Bearing housing is one of water pump vitals, and its performance directly has influence on water pump and runs well, and reaches the protection to environment.IS type series clean waterpump is no exception, the bearing gland at these bearing housing two ends, and its former project organization adopts the extending oil felt seal, prevents the leakage of bearing housing lubricant oil.But because the asphalt felt sealing effect is relatively poor, the fault-free sealing time is short, and oil leakage phenomenon is serious; Pollute the pump house environment, this material is loose in addition, and is fragile; Twisted into bearing when serious, made the bearing locking, caused the water pump disorderly closedown; Cause economic loss in various degree to the user, the prestige of product and social benefit all receive must be influenced.
The model utility content
The utility model technical problem to be solved provides the bearing gland on a kind of clean waterpump bearing housing, and its improvement is simple in structure but practical, adopts outside framework oil seal to seal; Sealing effect is good; No oil leakage phenomenon, and be difficult for the nature damage, so the no leakage failure time prolongs greatly.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
Bearing gland on a kind of clean waterpump bearing housing; Include bearing gland; The madial wall of described bearing gland is provided with the ring skeleton oil sealing; Be provided with an annular groove between the skeleton of described ring skeleton oil sealing and the rubber layer, spring is arranged in the annular groove, be provided with the oil sealing removal hole between the outer side wall of described ring skeleton oil sealing and bearing gland.
Consider not only in the utility model that outside framework oil seal installs, also designed the outside framework oil seal removal hole simultaneously, be convenient to the replacing after the aging or wearing and tearing of outside framework oil seal.
The rubber material stable performance of outside framework oil seal in the utility model, and have excellent elasticity, pump shaft as early as possible, outside framework oil seal is provided with spring to have about reinforcing.
The utility model has the advantages that:
The utility model improves simple in structure but practical, adopts outside framework oil seal to seal, and sealing effect is good, no oil leakage phenomenon, and be difficult for the nature damage, so the no leakage failure time prolongs greatly.
