Detailed Description
Please refer to fig. 1 to 4:
the embodiment provides a hydraulic machinery gear pump, including pump body 1, through-hole 2 has been seted up to the front end of pump body 1, and through-hole 2 runs through whole pump body 1, and inside through-connection of through-hole 2 has metal sheath 3, and two jack 4 have all been seted up to the front and back both sides of pump body 1 top and bottom, and every jack 4 all is fit with screw rod 5 to every jack 4 all link up through-hole 2.
The inside of metal sheath 3 is run through and is connected with rotatory axostylus axostyle 301, and four screw 302 with jack 4 adaptation respectively have all been seted up to the upper end and the lower extreme of metal sheath 3, through this kind of design, rotatory axostylus axostyle 301 is arranged in metal sheath 3, when installing metal sheath 3 in pump body 1, run through metal sheath 3 in pump body 1, can arrange rotatory axostylus axostyle 301 in pump body 1 in the lump, in this process, aim at eight screw 302 respectively with eight jack 4 from top to bottom, then pass through screw 5 spiral into jack 4 in, on this basis, screw 5 can penetrate into screw 302 in the lump, and then accomplish the installation of metal sheath 3 in pump body 1.
On the basis of the above, the middle end of the rotating shaft 301 is fixedly connected with the transmission gear 303, the inner middle end of the through hole 2 is provided with the internal gear 201, and the transmission gear 303 is in meshed connection with the internal gear 201, by the design, when the metal sheath 3 and the rotating shaft 301 are installed in the pump body 1, the transmission gear 303 can be in meshed connection with the internal gear 201 in the process, and when the transmission gear 303 rotates, the internal gear 201 can be driven to rotate, so that the gear pump operates, and a driving device of the transmission gear 303 is connected with an external power supply.
