Abstract
The utility model discloses a crosshead sliding block structure for a pressure fan. The crosshead sliding block structure comprises a big head tilting fillet and an oil hole, wherein the oil hole is positioned in the inner part of the lower end of the big head tilting fillet. The crosshead sliding block structure is characterized in that a tile lining is respectively arranged on each of the upper inner wall and the lower inner wall of the big head tilting fillet; an oil gallery is connected between the two tile linings; the lower end of the oil gallery penetrates through the lower tile lining, and is connected with the upper end of the oil hole; the tile lining positioned at the lower end of the big head tilting fillet is connected with a positioner; the positioner is inserted into the lower tile lining and the big head tilting fillet in an embedded manner; the surface of the positioner is lower than the external surface of the lower tile lining. The device is simple in structure and low in manufacturing cost, a transmission part of the pressure fan has no oil-way blocking phenomenon, and the fitting cost is saved.
Description
Technical field
The utility model relates to a kind of slide block structure, is specifically related to a kind of pressure fan crosshead slipper structure.
Background technique
The power that pressure fan is generally used in pneumatic equipment provides, and air pressure is shortened into the gas of certain pressure, provides power to pneumatic equipment, makes it running.For example supply the pneumatic equipments such as down-hole pneumatic pick, air pump.
Its crosshead slipper of existing pressure fan has lubricated circuit to be: oil pump-crankshaft hole center-connnecting rod big end watt-connecting rod center hole-crosshead pin and lining-crosshead slideway, the phenomenon and connnecting rod big end watt wherein is usually turn-taked, oilhole is stopped up, cause transmission position because of oil starvation part of damage, machine is often broken down, and maintenance expenses also increases greatly.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of pressure fan crosshead slipper structure, this apparatus structure is simple, fabricating cost is low, make pressure fan transmission position without oil circuit blocking phenomenon, saved fittings cost.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of pressure fan crosshead slipper structure, comprise major part watt seat and oilhole, oilhole is positioned at major part watt inside, seat lower end, it is characterized in that: in described major part watt seat, upper and lower inwall is respectively equipped with a watt lining, between two watts of linings, be connected with oil duct, described oil duct lower end is connected with oilhole upper end through lower watt of lining, and a watt lining that is positioned at major part watt seat below is connected with positioning work piece, and the embedded insertion of positioning work piece watt serves as a contrast and major part watt seat is interior and it is surperficial lower than a watt lining outer surface.
The beneficial effects of the utility model are: by installing positioning work piece additional in a major part watt seat inner side, it embeds in watt lining and major part watt seat, and its surface is lower than a watt lining surface, has avoided connnecting rod big end watt to turn-take, and has eliminated oil circuit blocking phenomenon.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure: 1-major part watt seat; 2-oilhole; 3-watt of lining; 4-oil duct; 5-positioning work piece.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of pressure fan crosshead slipper structure, comprise major part watt seat 1 and oilhole 2, oilhole 2 is positioned at major part watt seat 1 inside, lower end, be respectively equipped with 3, two watts of 3 of linings of watt lining at the interior upper and lower inwall of major part watt seat 1 and be connected with oil duct 4, oil duct 4 lower ends are connected with oilhole 2 upper ends through lower watt of lining 3, a watt lining 3 that is positioned at major part watt seat 1 below is connected with positioning work piece 5, and the embedded insertion of positioning work piece 5 watt lining 3 and major part watt seat 1 are interior and it is surperficial lower than watt lining 3 outer surfaces.By installing positioning work piece 5 additional in major part watt seat 1 inner side, it embeds in watt lining 3 and major part watt seat 1, and its surface is lower than watt lining 3 surfaces, has avoided connnecting rod big end watt to turn-take, and has eliminated oil circuit blocking phenomenon.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
