Description
Technical field
The present invention relates to a kind of hydraulic element, especially relate to a kind of hydraulic and indexing chuck oil separator.
Background technique
At present, hydraulic and indexing chuck mainly comprises copper alloy bushing and is arranged on the running shaft in copper alloy bushing with oil separator, owing to having gap between lining and running shaft, in the easy generation of long-term use, lets out, thereby make the pressure in oil hydraulic circuit produce loss, and then reduce the efficiency of hydraulic system.
In order to reduce the pressure loss, need to reduce the gap between lining and running shaft, so can make the friction between lining and running shaft strengthen, fricative amount of heat can make to produce adhesion interlock on friction pair, and equipment is produced to larger damage.
In order to address the above problem, conventional processing mode is at present: to the accurate grinding technique of endoporus for lining, to reduce gap and to reduce adhesion interlock risk, but this technology processing cost is high and technology difficulty is large.Copper alloy bushing need to be assembled in the frame of oil separator by the mode being pressed in addition, higher to the required precision of assembling, makes the difficulty of assembling larger.
Summary of the invention
Technical problem to be solved by this invention is to provide the hydraulic and indexing chuck oil separator of a kind of simple in structure, good sealing effect and low cost of manufacture.
The present invention solves the problems of the technologies described above adopted technological scheme:

On the inwall of described through hole, be provided with multiple annular grooves, described annular groove is arranged on adjacent described going out between oil pocket, between the annular groove described in described oil sealing is arranged on and described running shaft.This annular groove can position oil sealing, thereby guarantees the sealing effect of oil sealing.
Described oil sealing comprises the first seal ring and O RunddichtringO, described O RunddichtringO is set in the outside of the first described seal ring, described running shaft contacts with the inwall of described the first seal ring, the outer wall of described O RunddichtringO contacts with the bottom end of described annular groove, the bottom end transition fit of the outer wall of described O RunddichtringO and described annular groove.Oil sealing adopts the combination of the first seal ring and O RunddichtringO, and the outer wall of O RunddichtringO and the bottom end of annular groove are transition fit, now, O RunddichtringO is compressive state, during oil separator work, owing to having frictional force between the first seal ring and running shaft, long-term use, the first seal ring can wear and tear under the effect of this frictional force, and then generation gap, now O RunddichtringO is from compressive state slow release, and compensation, because of the gap that the first ring wear forms, has guaranteed the stability of sealing.
On the inwall of the first described seal ring, be provided with annular recess.This annular recess diminishes the area of contact between the inwall of the first seal ring and the outer wall of running shaft, thereby has reduced the frictional force between the inwall of the first seal ring and the outer wall of running shaft, makes running shaft running more smooth and easy.
Described annular recess is 2, and the annular recess described in 2 is symmetrical arranged.2 annular recess are symmetrical arranged, and make contact and lifting surface area comparatively even, thereby guarantee the smooth and easy rotation of running shaft.
The material of the first described seal ring is the mixture of teflon and carbon fiber.Oil separator can produce a large amount of heats when work, the temperature upper limit that common fluorine rubber can bear is 120 ℃-150 ℃, and the mixture of teflon and carbon fiber wear resistance under the temperature conditions of 80 ℃-200 ℃ is better, make the working life of sealing circle longer, save cost, and can effectively guarantee the stability of sealing.
The uniform ring-type radiating fin that is provided with on the outer wall of described housing.This ring-type radiating fin contributes to the heat producing while leaving oil separator work, thus the working life that strengthens this oil separator.
The material of described housing is steel.Use steel, reduced manufacture cost.
The bearing at the up and down two ends of described running shaft by being arranged on described housing is fixed in described housing.
Compared with prior art, the invention has the advantages that: saved original copper alloy bushing, through hole is directly set on housing, by oil sealing being set between through-hole wall and running shaft, in fluid because existing gap to cause between through hole and running shaft, let out preventing, simple in structure, reduced difficulty of processing, saved manufacture cost, saved complicated assembly technology, oil sealing is arranged on adjacent going out between oil pocket simultaneously, strengthened sealing effect, effectively reduce fluid in let out, thereby reduced the pressure loss in oil hydraulic circuit, the efficiency of hydraulic system is guaranteed.
