Abstract
The utility model relates to a resilience force is good, be difficult to damaged, long service life's single cylinder hydraulic pressure series top bearing seal circle, including top bearing seal circle, the sealing washer lip is the multichannel. The advantages are that: firstly, the resilience force is good, the damage is not easy to occur, and the service life is long; secondly, the sealing performance is reliable, and the phenomenon of lubricating grease leakage in the background technology is avoided.
Description
Technical Field
The utility model relates to a good, the difficult damaged, long service life's of resilience force single cylinder hydraulic pressure series top bearing seal circle belongs to top bearing seal circle and makes the field.
Background
The existing top bearing sealing ring adopts a framework-free J-shaped sealing ring in structural design, the resilience force of a J-shaped framework-free oil seal is insufficient when a single-cylinder hydraulic main shaft is swung in a rotating mode, the thickness of rubber at the corner of a sealing lip is thin, the service life is short, the period is short, and lubricating grease is easy to damage and cause leakage.
SUMMERY OF THE UTILITY MODEL
The design purpose is as follows: the defects in the background art are avoided, and the single-cylinder hydraulic series top bearing sealing ring which is good in resilience force, not easy to damage and long in service life is designed.
The design scheme is as follows: in order to achieve the above design objectives. The utility model increases the thickness of the corner of the sealing ring and is made of butadiene acrylonitrile rubber with the shore hardness of 70-80 degrees on the structural design, so that the resilience force of the two walls of the groove of the sealing ring is further enhanced; and secondly, the sealing ring lip is increased (only one lip is arranged on the J-shaped frameless oil seal), so that the sealing reliability is good, the service life is prolonged by more than one year and can reach 1-2 years.
The technical scheme is as follows: a single-cylinder hydraulic series top bearing sealing ring comprises a top bearing sealing ring, and a plurality of sealing ring lips.
Compared with the background technology, the utility model has the advantages of good resilience, difficult damage and long service life; secondly, the sealing performance is reliable, and the phenomenon of lubricating grease leakage in the background technology is avoided.
Drawings
Fig. 1 is a schematic structural diagram of a single-cylinder hydraulic series top bearing seal ring.
Fig. 2 is a partially enlarged schematic view of fig. 1.
Fig. 3 is a schematic view of the application of fig. 1 to a single cylinder hydraulic crusher.
Detailed Description
Example 1: refer to FIGS. 1-3. A single-cylinder hydraulic series top bearing seal ring comprises a top bearing seal ring 1 and a plurality of seal ring lips 2. The rubber thickness of the lip corner of the sealing ring is thick and nitrile-butadiene rubber is adopted. The rubber thickness of the lip corner of the sealing ring 1 is larger than the wall thickness of the groove. The angle of the arc-shaped groove 3 on the end surface of the sealing ring is 38.5-39.5 degrees. Namely, the sealing ring material is nitrile rubber, the Shore hardness is 70-80 degrees, the resilience force of the sealing ring is increased, the thickness of a corner is increased, and a plurality of sealing ring lips are added (in the prior art, only one lip is arranged on the J-shaped frameless oil seal), so that the service life can reach more than 1-2 years. Reference numeral 4 is a top bearing.
It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
Claims (1)
