Abstract
The utility model relates to a gear sundstrand pump. The gear sundstrand pump comprises a pump body, a pump cover, a driving gear, a driven gear, a revolution axis, a bearing, a sealing element and installation parts. The gear sundstrand pump mainly adopts an annular gear as the driving gear, and the revolution axis at both sides of the driving gear adopt a rolling bearing for supporting. The utility model has the advantages of stable running, rotational speed raising and high running efficiency, and being suitable for the delivery device of the oil product in the oil pipeline of the fuel charger.
Description
Technical field
The utility model relates to a kind of pump, specifically about a kind of gear type unipump.The utility model is applicable to the feedway of oil product on the oilling machine oil transport pipeline.
Background technique
Gear pump is to use commonplace device on the oilling machine, generally is made up of the pump housing, pump cover, driving gear, driven gear, rotating shaft, bearing and Sealing and assembling set.The outlet of its pump housing deaerator of directly ining succession, so, usually pump and deaerator are lumped together and be called unipump.Yet existing gear type unipump all is that the employing external rotor is a driving gear, and internal rotor is a driven gear, i.e. rotating shaft is fixedly connected on the external rotor.For the volume that do not make pump is too big, its rotating shaft can only be adopted monolateral supporting, and generally adopts sliding supported condition, has limited the running stability and the rotating speed of pump, influences the operational efficiency of pump.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, the gear type unipump that provide a kind of and operate steadily, efficient is high.
The technological scheme that realizes the utility model purpose comprises the pump housing, pump cover, driving gear, driven gear, rotating shaft, bearing and Sealing and assembling set, mainly is that the employing internal gear is a driving gear, and the rolling bearing supporting is adopted in the rotating shaft of driving gear both sides.
The utility model beneficial effect compared with prior art is to adopt the rolling bearing supporting in the rotating shaft of driving gear both sides, makes pump operation steady, improves the rotating speed and the operational efficiency of pump.
Description of drawings
Fig. 1 is the structural representation of the utility model pump part.
Embodiment
Now further describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments.
Gear type unipump as shown in Figure 1, structure comprises the pump housing 1, pump cover 7, driving gear, driven gear, rotating shaft 15, bearing and Sealing and assembling set, internal gear 4 is fixedlyed connected by flat key 5 with rotating shaft 15, internal gear 4 cooperatively interacts with external gear 3 and constitutes driving gear and driven gear, and rolling bearing 10,16 supportings are adopted in driving gear both sides rotating shaft 15.Be provided with pump housing lining 2 between the pump housing 1 and the external gear 3, and be provided with O-ring seals 6 between the pump cover 7, and fixedly connected by bolt 13.Rolling bearing 10 is a deep groove ball bearing, press-fit in pump cover 7 by bearing gland 11, and be provided with outside framework oil seal 8 between the pump cover 7, be provided with end ring 9 between the two, bearing gland 11 is installed on the pump cover 7 by screw 12, is provided with locating stud 13 between pump cover 7 and the pump housing lining 2.Rolling bearing 16 is a needle bearing, places between rotating shaft 15 and the pump housing lining 2, and is provided with outside framework oil seal between the internal gear 4.
