Description
Technical field
The utility model relates to a kind of box coupling and extracting tool thereof, particularly relates to a kind of pump series products box couplings such as vertical diagonal flow pump, vertical long shaft pump, vertical condensate extractionpump that are applied to, and the utility model also relates to the extracting tool of this box coupling.
Background technique
Box coupling is the parts that are used for two axles of rigid joint, be widely used in vertical diagonal flow pump, vertical long shaft pump, vertical condensate extractionpump etc., its structure snaps in the groove of two axle heads for connecting snap ring, box coupling is connected into one securely with two axles, and the thrust snap ring is fixed on box coupling on the axle.Box coupling has simple in structure, and is easy for installation, the unrestricted characteristics of the moment of torsion of transmission and rotating speed.But because box coupling oversize with the length of thread engagement of upper and lower main shaft (being directly proportional) with the size of transmitting torque, after long-term the use,, even can't dismantle because corrosion causes the dismounting difficulty, have to take destroy dismounting, this will bring on the time and loss economically to the user.
The model utility content
Technical problem to be solved in the utility model provides a kind of easy-to-dismount box coupling.
Second technical problem that the utility model also will solve provides a kind of extracting tool of box coupling of simple in structure, reliable performance.
In order to solve the problems of the technologies described above, the box coupling that the utility model provides, comprise box coupling, the internal diameter of described box coupling and last main shaft cooperation place is little with the internal diameter of lower main axis cooperation place, and in the middle of the inwall of length of thread engagement, be provided with the processing shelves that fall, be provided with draw-in groove at the outer wall of described box coupling.
The internal diameter of described box coupling and last main shaft cooperation place with the little 0.5mm of internal diameter of lower main axis cooperation place.
The extracting tool that the utility model provides, comprise the first dismounting snap ring and the corresponding second dismounting snap ring that snaps in described draw-in groove, the described first dismounting snap ring and the second dismounting snap ring adopt and divide the half hitch structure, and it is an integral body that the described first dismounting snap ring and the second dismounting snap ring connect by long bolt and nut.
Adopt the box coupling of technique scheme, during assembling, connect snap ring and snap in the groove of main shaft and lower main axis end, box coupling is connected into one securely with two axles, and the thrust snap ring is fixed on box coupling on the lower main axis.
During dismounting, pulling down the thrust snap ring earlier, the first dismounting snap ring, the second dismounting snap ring are stuck in the draw-in groove of the groove of main shaft and box coupling, is an integral body by long bolt and nut with the first dismounting snap ring and the second dismounting snap ring connection.The screw up with a wrench nut at the first dismounting snap ring place, long bolt just can drive the second dismounting snap ring and box coupling moves on axle, thereby pulls down box coupling smoothly.
Owing to adopt box coupling little, and the processing shelves that fall are arranged in the middle of the inwall of length of thread engagement with the internal diameter of lower main axis cooperation place with the internal diameter of last main shaft cooperation place, thus frictional force and dismounting contact length when having reduced dismounting widely, so dismantle very convenient.
The box coupling of employing technique scheme and extracting tool thereof are compared with original technology has following advantage:
1, adopt box coupling that two internal diameter varies in size and in the middle of length of thread engagement the processing shelves that fall, thereby frictional force and dismounting contact length when having reduced dismounting are widely dismantled very convenient.
2, the box coupling extracting tool is simple in structure, and is easy to use, improved user's maintenance work efficiency greatly, saved time and fund cost.
In sum, the utility model is a kind of easy-to-dismount box coupling, compact structure, easy to use, extensively be used on vertical diagonal flow pump, vertical long shaft pump, the vertical condensate extractionpump, have very strong practical and popularizing value, simple in structure, the reliable performance of extracting tool.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the internal diameter 10 of box coupling 1 and last main shaft 7 cooperation places with the internal diameter 11 little 0.5mm of lower main axis 8 cooperation places, and in the middle of the inwall of length of thread engagement, be provided with the processing shelves 12 that fall, be provided with draw-in groove 9 at the outer wall of box coupling 1.
Referring to Fig. 4, extracting tool comprises the first dismounting snap ring 4 and the corresponding second dismounting snap rings 5 that snap in draw-in groove 9, the first dismounting snap ring 4 and the second dismounting snap ring 5 adopt and divide the half hitch structure, and it is an integral body that the first dismounting snap ring 4 and the second dismounting snap ring 5 connect by long bolt 6 and nut 13.
Referring to Fig. 3, during assembling, connect snap ring 2 and snap in the groove of main shaft 7 and lower main axis 8 ends, box coupling 1 is connected into one securely with two axles, and thrust snap ring 3 is fixed on box coupling 1 on the lower main axis 8.Referring to Fig. 1, the internal diameter 11 of box coupling 1 and last main shaft 7 cooperation places with the internal diameter 12 little 0.5mm of lower main axis 8 cooperation places, and in the middle of length of thread engagement the processing shelves 12 that fall.Thrust
Referring to Fig. 4, during dismounting, pull down earlier and connect snap ring 3, in the draw-in groove 9 that divides half the first dismounting snap ring 4, groove 14 that the second dismounting snap ring 5 is stuck in main shaft 7 and box coupling 1, dismantling snap ring 4, second with long bolt 6 and nut 13 with first, to dismantle snap ring 5 connections be an integral body.The screw up with a wrench nut 13 at first dismounting snap ring 4 places, long bolt 6 just can drive the second dismounting snap ring 5 and box coupling 1 moves on axle, thereby pulls down box coupling smoothly.
