Abstract
The utility model discloses a revolving body of a piston pushing centrifugal machine. The revolving body of the piston pushing centrifugal machine comprises a main shaft (1), a front shaft sleeve (3) connected with the main shaft (1) is arranged in the main shaft (1), and a pushing rod (2) penetrating through the front shaft sleeve (3) is arranged in the main shaft (1). An orifice plug (4) penetrating through the pushing rod (2) is arranged on the pushing rod (2), a boss (5) is arranged at the position, next to the orifice plug (4), on the inner wall of the main shaft (1), and a gap is formed between the inner circle of the boss (5) and the outer circle of the small end of the pushing rod (2). The revolving body of the piston pushing centrifugal machine has the advantages of being ingenious in design and simple in structure. By the adoption of the revolving body of the piston pushing centrifugal machine, the flow of lubricating oil of the front shaft sleeve can be accurately controlled, and lubrication of the front shaft sleeve is guaranteed.
Description
Technical field
The utility model relates to a kind of piston push centrifuge, particularly a kind of piston push centrifuge revolving body.
Background technology
At present, the revolving body of piston push centrifuge mainly comprises main shaft, is provided with the push rod through main shaft in main shaft, between push rod and main shaft, is provided with the front shaft sleeve being connected with main shaft, on push rod, be provided with the orifice plug that runs through push rod, described this orifice plug is corresponding with front shaft sleeve; Main shaft and push rod are when making synchronous rotary, and push rod moves forward and backward in front shaft sleeve, and the lubricating oil in push rod is entered in front shaft sleeve by orifice plug, and front shaft sleeve is lubricated.Wherein, the number that lubricating oil enters, relevant with the diameter of bore of orifice plug, when the endoporus of orifice plug is excessive, it is too many that lubricating oil enters front shaft sleeve, and when the endoporus of orifice plug is too small, easily suffer the obstruction of tiny iron filings in lubricating oil, lubricating oil cannot enter into front shaft sleeve, is unfavorable for the lubricated of front shaft sleeve.
Utility model content
The purpose of this utility model is just to provide a kind of piston push centrifuge revolving body that can accurately control flow of lubrication.
The purpose of this utility model is to realize by such technical scheme, a kind of piston push centrifuge revolving body, comprise main shaft, in main shaft, be provided with the front shaft sleeve being connected with main shaft, in main shaft, be provided with the push rod through front shaft sleeve, on described push rod, be provided with the orifice plug that runs through push rod, it is characterized in that: on the inwall of described main shaft and next-door neighbour orifice plug be provided with boss, between described boss internal diameter and the small end cylindrical of push rod, there is gap.
Further describe, the internal diameter of described boss is greater than push rod small end external diameter and is less than front shaft sleeve internal orifice dimension.
Owing to having adopted technique scheme, the utlity model has design advantage ingenious, simple in structure, adopt it can control accurately the flow of lubrication of front shaft sleeve, guaranteed the lubricated of front shaft sleeve.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Structural representation when Fig. 1 is of the present utility model advancing;
As 2 when of the present utility model the retreating structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or substitute, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of piston push centrifuge revolving body, comprise main shaft 1, in main shaft 1, be provided with the front shaft sleeve 3 being connected with main shaft 1, in main shaft 1, be provided with the push rod 2 through front shaft sleeve 3, on described push rod 2, be provided with the orifice plug 4 that runs through push rod 2, on the inwall of described main shaft 1 and next-door neighbour orifice plug 4 be provided with boss 5, between described boss 5 internal diameters and the small end cylindrical of push rod 2, there is gap.
Wherein, the internal diameter of described boss 5 is greater than push rod 2 small end external diameters and is less than front shaft sleeve 3 internal orifice dimensions.
In the utility model, at push rod 2, move forward in process, lubricating oil flows out main shafts 1 from boss 5 lefts, and at push rod, backward in moving process, lubricating oil is just lubricated front shaft sleeve 3.The stroke moving forward and backward due to push rod 2 is a definite value, has so just controlled the lubrication flow to front shaft sleeve 3.
Claims (2)
1. a piston push centrifuge revolving body, comprise main shaft (1), in main shaft (1), be provided with the front shaft sleeve (3) being connected with main shaft (1), in main shaft (1), be provided with the push rod (2) through front shaft sleeve (3), on described push rod (2), be provided with the orifice plug (4) that runs through push rod (2), it is characterized in that: on the inwall of described main shaft (1) and next-door neighbour orifice plug (4) be provided with boss (5), between described boss (5) internal diameter and the small end cylindrical of push rod (2), there is gap.
2. piston push centrifuge revolving body as claimed in claim 1, is characterized in that: the internal diameter of described boss (5) is greater than push rod (2) small end external diameter and is less than front shaft sleeve (3) internal orifice dimension.
