Abstract
The utility model relates to an easy-to-disassemble motor for a plunger pump. The outer lateral end of a rotating shaft is embedded in an end cover, or the surface of the outer lateral end of the rotating shaft is flushed with the outer lateral end face of the end cover, a shaft hole for being connected with a transmission shaft of the plunger pump is coaxially formed in the rotating shaft, one or a plurality of key grooves are formed on the inner wall of the shaft hole in the radial direction, and a plurality of installation holes for being connected with the plunger pump are evenly arranged on the outer lateral end face of the end cover in the radial direction. In the easy-to-disassemble motor for the plunger pump, length of the rotating shaft of the motor is shortened, the rotating shaft is embedded in the end cover, the shaft hole is formed in the end cover, the key grooves are formed on the shaft hole, the installation seat and the end cover of the plunger pump are fixed on bolts in the installation holes formed in the end cover, and the transmission shaft of the plunger pump extends into the shaft hole and is in linkage with the shaft hole through the key grooves. Due to the fact that length of the rotating shaft is shortened, integral volume is minimized, coaxiality is precise, the motor can be used in a horizontal mode and also can be vertically used by additionally arranging a plurality of flanges, and therefore, the easy-to-disassemble motor for the plunger pump is convenient.
Description
Technical field
The utility model relates to the interconnection technique field of plunger displacement pump and drive motors, especially a kind of plunger displacement pump motor easy to assemble.
Background technology
Plunger displacement pump is used for the circulation of fluid, and it relies on the reciprocating motion of plunger by motor-driven, the volume of seal operation cavity is changed realize oil suction, force feed, has the advantages such as compact conformation, efficient high flow capacity be easy to adjust.During use, the power transmission shaft of plunger displacement pump is connected with the output shaft of motor firmly by equipment such as shaft couplings or is flexible coupling, the output shaft of motor passes and stretches into enclosure behind the electric motor end cap and be connected with rotor, and the part that output shaft is positioned at end cap is connected with end cap by bearing.
In the said structure, the device structures such as shaft coupling between motor and the plunger displacement pump are complicated, and are very inconvenient when installation, dismounting, and increased whole length, and the installation site is restricted.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of scientific and reasonable for structure, compact a kind of plunger displacement pump motor easy to assemble is provided.
The technical scheme that the utility model is taked is:
A kind of plunger displacement pump motor easy to assemble, comprise shell, end cap and output shaft, end cap is installed in an end of shell, in end cap, rotate the setting-in output shaft, it is characterized in that: the outboard end of described rotation axis is inlaid in the end cap or the surface of the outboard end of described rotation axis and end cap outside end face, the coaxial axis hole for connection plunger pump drive shaft of making in rotation axis, radially make one or more keyways on this shaft hole inner wall, described end cap outboard end face diameter is made a plurality of installing holes for connecting plunger displacement pump to uniform.
And described end cap outboard end face diameter is to a plurality of supports being installed, the common ring flange coaxial with end cap that connect of these a plurality of supports.
And described end cap outside end face installs one for the mounting flange that connects fuel tank, and the outboard end face diameter of this mounting flange is to a plurality of supports being installed, the common ring flange coaxial with end cap that connect of these a plurality of supports.
Advantage of the present utility model and good effect are:
In the utility model, the rotation axis length of motor shortens, and is inlaid in the end cap, make axis hole on it, make keyway at axis hole, during connection, the mount pad of plunger displacement pump and end cap are fixed by the bolt in the made installing hole of end cap, the power transmission shaft of plunger displacement pump stretches in the axis hole and by the keyway interlock, because rotation axis length is dwindled, makes whole volume-diminished, concentricity is more accurate, and this motor can horizontally use, and also can realize vertical use by installing a plurality of ring flanges additional, and is very convenient.

Fig. 1 is vertical view of the present utility model;
Fig. 2 is the end cap of Fig. 1, the sectional view of rotation axis;
Fig. 3 is a kind of malformation of the end cap of Fig. 1;
Fig. 4 is the another kind of malformation of the end cap of Fig. 1.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection range of the present utility model with following embodiment.
A kind of plunger displacement pump motor easy to assemble, shown in Fig. 1～4, comprise shell 4, end cap 3 and rotation axis 14, hanger 5 is installed on the shell, mounting seat 6 under the shell, end cap is installed in an end of shell and fixes by the bolt in the through hole 8, in end cap, rotate the setting-in output shaft, innovation of the present utility model is: the outboard end of described rotation axis is inlaid in the end cap or the surface of the outboard end of described rotation axis and end cap outside end face, the coaxial axis hole 13 for connection plunger displacement pump 1 power transmission shaft 17 of making in rotation axis, radially make one or more keyways 12 on this shaft hole inner wall, described end cap outboard end face diameter is made a plurality of installing holes 9 for connecting plunger displacement pump to uniform.
In the present embodiment, the outboard end of rotation axis is inlaid in the end cap, and its outer rim is installed in the annular ridge 10 by bearing 11, and on the mount pad 2 of the made boss 7 crimping plunger displacement pumps of the outside end face of end cap, the two is fixed by the bolt in the installing hole.
The motor of said structure can be used for horizontal machine, in addition, structure as shown in Figure 3 also can be used for horizontal machine, end cap outboard end face diameter is to a plurality of supports 16 are installed, the common ring flange 15 coaxial with end cap that connect of these a plurality of supports, this ring flange connects the mount pad of plunger displacement pump, and the power transmission shaft of plunger displacement pump is realized the two interlock in ring flange, support stretch into the rotation axis of motor.
Because motor may use on the vertical direction, as shown in Figure 4, end cap outside end face installs one for the mounting flange 19 that connects fuel tank, and the outboard end face diameter of this mounting flange is to a plurality of supports 16 being installed, the common ring flange 15 coaxial with end cap that connect of these a plurality of supports.Mounting flange is used for connecting the outer wall 18 of fuel tank, and following ring flange 15 connects the mount pad of plunger displacement pump, and the power transmission shaft of plunger displacement pump is realized the two interlock in ring flange, support stretch into the rotation axis of motor.
In the utility model, the rotation axis length of motor shortens, and is inlaid in the end cap, make axis hole on it, make keyway at axis hole, during connection, the mount pad of plunger displacement pump and end cap are fixed by the bolt in the made installing hole of end cap, the power transmission shaft of plunger displacement pump stretches in the axis hole and by the keyway interlock, because rotation axis length is dwindled, makes whole volume-diminished, concentricity is more accurate, and this motor can horizontally use, and also can realize vertical use by installing a plurality of ring flanges additional, and is very convenient.
