Accompanying drawing explanation
Fig. 1 is integrally-built sectional view of the present utility model。
Fig. 2 is the sectional view of partial structurtes of the present utility model。
Fig. 3 is the sectional view of partial structurtes of the present utility model。
Detailed description of the invention
This utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1 Fig. 3；
This gives a kind of novel petrochemical industry single screw compressor being conveniently replaceable grease, including casing 1, screw rod 2 and free end bearing 3。Generally, described free end bearing is cylinder roller bearing。Casing 1 is fixed with bearing block 4, and as shown in fig. 1, bearing block is provided with a receiving compartment assembled for free end bearing, and receiving compartment is arranged with screw coaxial line。
One end of bearing block 4 is fixed with inner end cap 5, and the other end of bearing block 4 is fixed with outer end cap 6。Inner end cap, outer end cap all seal with bearing block and coordinate, and as shown in fig. 1, receiving compartment is surrounded chamber 7 by inner end cap, outer end cap, to receive the grease for lubricating free end bearing。Inner end cap 5 is provided with through hole, and inner ring with free end bearing 3 socket-connects through through hole for the free end of screw shaft, and the outer ring of free end bearing 3 is connected with bearing block 4。The power end of screw shaft is cased with fixing end bearing 8。It should be noted that accept power equipped with the power end of fixing end bearing rotated for being connected with the outfan of dynamical system on screw shaft。It is fixed on the screw rod on screw shaft to be also meshed with the star-wheel of two centrosymmetry layouts, compresses gas by screw rod with the realization that coordinates of star-wheel。The spiral fluted front portion being positioned at screw rod in casing is provided with chamber 14, is additionally provided with oil drain out 15 in casing 1, and oil drain out is connected with chamber, is removably provided with oil drain out plug on oil drain out。Generally, oil drain out plug。By arranging oil drain out and the structure of oil drain out plug, before start, can will disassemble oil drain out plug, the lubricating oil accumulated in chamber is discharged, again oil drain out plug is screwed up on oil drain out again after end, it is possible to be effectively prevented screw rod and star-wheel occurs the phenomenon of liquid hammer in the course of the work。
Setting greasing mouth 11 on outer end cap, greasing mouth is connected with receiving compartment, to inject grease by greasing mouth to fixing end bearing。The row's of being provided with fat mouth 12 in inner end cap, row's fat mouth is connected with receiving compartment, to pass through to arrange fat mouth by the grease discharge in receiving compartment。Being also associated with skirt 13 in inner end cap, skirt is connected with row's fat mouth。By skirt, the grease flowed out from row's fat mouth is guided to the outside of casing, it is to avoid grease sticks in casing in changing grease process。
Being provided with screw thread 9 on the hole wall of through hole, the rotation direction of screw thread is contrary with the direction of rotation of screw rod 2。By adopting helicitic texture structure, when screw shaft rotates, it is possible to the lubricating oil between inner end cap and screw shaft is brought back in chamber, therefore after screw shaft rotates, by, in the gap that helicitic texture can stop grease to enter between inner end cap and screw shaft, being effectively prevented from grease and reveal。
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model。
