Description
Technical field
The utility model relates to a kind of high leak tightness screw air compressor bearing support.
Background technique
Screw air compressor bearing support on market, all common grey iron is processed after by conventional cast technique, and processing back cabinet and bearing support are bolted formation, and this just forms handpiece of air compressor frame-generic.Meanwhile, as the bearing support of vitals, in bearing support, all important oilholes are all bolted, and because tapped hole outerplanar is black skin, exist precision not in place, and installation can not closely cooperate, and easily produces leakage of oil.
Model utility content
For above-mentioned defect, it is a kind of easy for installation that the purpose of this utility model is to provide, and size is accurate, and sealability is high, makes it more steadily a kind of high leak tightness screw air compressor bearing support of safety of compressor operation.
The technological scheme that the utility model adopts is for this reason:
Comprise bearing support, described bearing support is provided with oil-feed tapped hole and two sealing thread holes, the flattening end surface of described oil-feed tapped hole is processed, in the front end of oil-feed tapped hole, be provided with step I, step I is provided with rubber seal ring I, the flattening end surface in described sealing thread hole is processed, and is provided with step II in the upper end in sealing thread hole, and step II is provided with rubber seal ring II.
The flat degree of depth of described ream is 1mm.
Described rubber seal ring I exterior edge face is lower than the end face of oil-feed tapped hole.
Described rubber seal ring II exterior edge face is lower than the end face in sealing thread hole.
The utility model has the advantages that:
The utility model is easy for installation, and size is accurate, and sealability is high, can make more steadily safety of compressor operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is bearing support, the 2nd, oil-feed tapped hole, the 3rd, sealing thread hole, the 4th, rubber seal ring I, the 5th, rubber seal ring II.
Embodiment
A kind of high leak tightness screw air compressor bearing support, comprise bearing support 1, described bearing support 1 is provided with oil-feed tapped hole 2 and two sealing thread holes 3, the flattening end surface of described oil-feed tapped hole 2 is processed, in the front end of oil-feed tapped hole 2, be provided with step I, step I is provided with rubber seal ring I4, and the flattening end surface in described sealing thread hole 3 is processed, in the upper end in sealing thread hole 3, be provided with step II, step II is provided with rubber seal ring II5.
The flat degree of depth of ream described in the utility model is 1mm.
Rubber seal ring I4 described in the utility model exterior edge face is lower than the end face of oil-feed tapped hole 2.
Rubber seal ring II5 described in the utility model exterior edge face is lower than the end face in sealing thread hole 3.
