Spring, it is extremely easy to drop, increase installation difficulty；Second is that easily making framework deformation, sealing performance is reduced, cost is caused to waste, is increased
Workload；Third is that being easy to cause the generation for phenomena such as hurting hand, damage tool, oil sealing without dedicated installation tool.
Summary of the invention
The purpose of this utility model is just to provide a kind of mitigation operator's large labor intensity, and time-consuming for operation, improves work
Efficiency and the double half a month ring type polymer-injecting pump belt pulley oil sealing installation tools for preventing from hurting hand and the damage of tool oil sealing.
The purpose of this utility model is realized by following technical proposals:
The utility model includes: axle sleeve, mandril, support sleeve, positioning bolt, gasket；It is characterized in that: the axle sleeve is three-level
Stepped cylinder hollow structure, intermediate outer are greater than left end outer diameter, and left end outer diameter is greater than right end outer diameter, and right end end socket center is equipped with
Tapped through hole, tapped through hole are provided with mandril, and the semicircle support sleeve of two halves structure is covered in the left end of axle sleeve, and support sleeve is equipped with spiral shell
Line through-hole, there is positioning bolt on tapped through hole, and positioning bolt positions support sleeve and axle sleeve.
Two-stage stepped hole is set in axle sleeve in above-mentioned double half a month ring type polymer-injecting pump belt pulley oil sealing installation tools, in left end
Diameter is greater than right end internal diameter, is equipped with an annular groove among inner hole, left end is symmetrically arranged with Blind locating holes.
Mandril in above-mentioned double half a month ring type polymer-injecting pump belt pulley oil sealing installation tools is equipped with external screw thread, and left end is equipped with circular cone
Top, right end is equipped with four directions or six square toes.
The semicircle support sleeve of two halves structure in above-mentioned double half a month ring type polymer-injecting pump belt pulley oil sealing installation tools is formed
There are certain interval in the cylindrical tube of two-stage ladder, centre, and left end is set as 1.5-2.5mm oil sealing lantern ring, the outer diameter of oil sealing lantern ring
Less than right end outer diameter.
Positioning bolt in above-mentioned double half a month ring type polymer-injecting pump belt pulley oil sealing installation tools is interior six square bolt, positions spiral shell
Gasket is equipped between bolt and support sleeve.
The beneficial effects of the utility model are: being equipped with the support sleeve of plurality of specifications, used for different model oil sealing, peace
It is convenient to fill, and simplifies operating procedure, reduces oil sealing spoilage, improves work efficiency, and has structure simple, easy to operate,
Securely and reliably, strong applicability.
Detailed description of the invention
Fig. 1-the utility model main view complete section structural schematic diagram.
In attached drawing, 1. axle sleeves, 2. mandrils, 3. support sleeves, 301. oil sealing lantern rings；4. positioning bolt, 5. gaskets；H. annular
Slot, D. Blind locating holes.
Specific embodiment
With reference to the accompanying drawing, the utility model will be further described:
As shown in Figure 1, double half a month ring type polymer-injecting pump belt pulley oil sealing installation tools are by axle sleeve 1, mandril 2, support sleeve 3, fixed
