Abstract
The utility model discloses a conjoined gear pump. The conjoined gear pump is characterized in that a front cover (1) is connected with a conjoined pump body (4) as a whole through a locating pin (2) and a locating bolt (3); a floating shaft sleeve (5), a driving gear shaft (6) and a driven gear shaft (7) are mounted into the conjoined pump body (4); an outer seal ring (8) and an inner seal ring (9) are respectively mounted between the front cover (1) and the conjoined pump body (4), as well as between the front cover (1) and the floating shaft sleeve (5); a pair of framework oil seals (10) are mounted onto the driving gear shaft (6) at the front end of the front cover (1) to form a seal space, therefore, the conjoined gear pump can be composed. The conjoined gear pump is provided with a two-piece structure, so that the amount of parts is decreased, the machining is easy, the rigidity is improved, the pump body is prevented from statically deforming at high pressure, a proper clearance between the pump body and the shaft sleeve can be ensured, the problem due to the leakage from the rear end surface is completely avoided, the volumetric efficiency is increased, and the working efficiency of the gear pump is improved.
Description
Technical field
The utility model relates to gear pump, is specifically related to the disjunctor gear pump.
Background technique
The three pieces type structure that common gear pump is made up of the pump housing that a pair of gear is housed and protecgulum and bonnet.The pump housing, front and rear covers and link are done as a whole, in the quiet distortion of high-pressure situations lower pump body meeting, make the gap smaller of the pump housing and floating buss, influence the axle sleeve floatability, increase fluid and reveal, and reduce the gear pump working efficiency.
Summary of the invention
The purpose of this utility model is: a kind of disjunctor gear pump is provided, adopts the two-piece type structure, strengthen the integral rigidity of the pump housing, reduce the pump housing quiet distortion under high pressure, reduce the link number, stop ear end face fluid and reveal, improve volumetric efficiency.
Technical solution of the present utility model is: this disjunctor gear pump comprises protecgulum, the disjunctor pump housing, floating buss, driving gear shaft and passive tooth wheel shaft, protecgulum connects into an integral body by locating stud and holding down bolt and the disjunctor pump housing, in the disjunctor pump housing, pack into floating buss, driving gear shaft and passive tooth wheel shaft, between protecgulum and the disjunctor pump housing and the floating buss exterior seal ring and inner seal ring are installed respectively, be positioned at and a pair of outside framework oil seal is installed on the driving gear shaft of protecgulum front end is formed seal space, wholely constitute the disjunctor gear pump.
The utility model two-piece type structure, the part number has been lacked, easy processing, rigidity strengthens, and avoids the quiet distortion of high-pressure situations lower pump body, guarantees the good gap of the pump housing and shaft room, thoroughly stop the ear end face leakage problem, improved volumetric efficiency, strengthened the working efficiency of gear pump.
