Abstract
The utility model provides a kind of Novel shaft side mechanical oil seal, is characterized in being provided with mechanical sealing friction pairs in the axle side lubricant reservoir inside end cap, is provided with disc spring compensation mechanism between the stationary seat of the stationary ring of described mechanical sealing friction pairs and end cap.The technical program have employed the mechanical sealing friction pairs structure being applicable to being arranged at narrow space between end cap and the shaft shoulder, achieve the endurable technical purpose of sealing, and its sealability is more superior.
Description
Technical field
The utility model relates to the sealing mechanism stoping lube shaft to side leakage.
Background technique
What avoid the seal arrangement of rotating shaft axial lubrication side leakage generally to adopt is skeleton rubber oil seal, has and arranges the narrow and small technical characterstic that takes up room.But because rubber component wear-resisting property is poor, cause oil leak with shaft contacts part because of wearing and tearing, working life is short, sealing effect is poor, and maintenance workload is larger.
Summary of the invention
Goal of the invention of the present utility model is that providing a kind of is suitable for the axle side mechanical oil seal that setting, sealing and endurance are excellent in the small space of existing axle side.The axle side mechanical oil seal technological scheme that the utility model provides, its main technical content is: a kind of axle side mechanical oil seal, mechanical sealing friction pairs is provided with in axle side lubricant reservoir inside end cap, the dynamic matching pair that described mechanical sealing friction pairs is made up of stationary ring and rotating ring, is provided with disc spring compensation mechanism between the stationary seat of stationary ring and end cap.
Axle side mechanical oil seal technological scheme disclosed in the utility model, have employed the mechanical sealing friction pairs structure being applicable to being arranged at limited space between end cap and the shaft shoulder, adopt disc spring as the compensation mechanism of mechanical sealing friction pairs, lubricant oil in space ensure that oil sealing, the Cooling and Lubricator of mechanical seal matching pair, there is sealability and play lasting technical characterstic, its maintenance greatly reduces, particularly between stationary seat and butterfly spring compensation mechanism, there is labyrinth type oil sealing configuration, make the sealability of its this seal assembly more superior.
Accompanying drawing explanation
Accompanying drawing is cut-open view of final assembly of the present utility model.
Embodiment
Axle side mechanical oil seal disclosed in the utility model, one typical case implements structure as shown in drawings.Mechanical sealing friction pairs is provided with in axle side lubricant reservoir 8 inside end cap 6.The core component of described mechanical sealing friction pairs is stationary ring 3 and the rotating ring 2 of the dynamic cooperation of sealing, and rotating ring 2 is fixedly mounted in rotating shaft 1, is provided with disc spring compensation mechanism between the stationary seat 7 of stationary ring 3 and end cap 6.What the outer annular space formed between the disc spring seat 5 of this disc spring compensation mechanism and stationary seat 7 formed disc spring 4 arranges chamber, gap and between stationary seat 7 and end cap 6, seal ring is set between disc spring seat 5 and stationary seat 7, the chamber that arranges of disc spring 4 constitutes labyrinth seal structure to seal ring between disc spring seat 5 and stationary seat 7, further ensures sealing effect.
Claims (2)
