Abstract
The utility model discloses a kind of non-viscous liquid medium transport gear pump, and it adopts a pair synchromesh gear drive pump gear, by adjusting the fit up gap of synchromesh gear, ensures that pump gear pair does not contact in the course of the work all the time.Being placed in by bearing outside gear pump body adopts grease lubrication not rely on pumped medium to lubricate.This structure successfully avoids the existence of friction pair in the pump housing, do not have friction pair then without the need to forming lubricant film, thus can in order to carry non-viscous fluid body medium.
Description
Technical field
The utility model belongs to gear pump field, particularly relates to a kind of non-viscous liquid medium transport gear pump.
Background technique
The existing gear pump of the structures shape of the gear pump of existing form is all rely on the resisting medium of gear pump conveying to lubricate the gear pair of gear pump and bearing.If pumped medium does not have viscosity, the lubricant film so between gear pair and between transmission shaft and bearing cannot be set up.Lubricant film can not set up and gear pair and bearing dry friction will be caused to cause bearing and the locking of gear pair axle journal, the serious consequence that gear pump cannot work on.
Model utility content
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, and provides a kind of non-viscous liquid medium transport gear pump.
The utility model realizes the technological scheme that above-mentioned purpose adopts: a kind of non-viscous liquid medium transport gear pump, it comprise there is liquid entering hole and the pump housing of liquid outlet, the left and right bearing housing be connected with pump housing two ends respectively, the bonnet be connected with left and right bearing housing collar extension end respectively and protecgulum and in the mode be parallel to each other up and down through the driving shaft of protecgulum, right bearing casing, the pump housing, left bearing casing and bonnet and driven shaft; The driving shaft of described pump body and driven shaft are respectively arranged with a non-touching pump gear, and the two ends of described pump gear are provided with the mechanical seal for sealing pump chamber respectively by distance ring; Described driving shaft and driven shaft are by being arranged on the roller bearings in left and right bearing housing, the outer end of rolling bearing is held out against by adjusting nut and adjusts pump gear end clearance, and described rolling bearing with between pump gear by mechanical seal and be arranged on oil sealing sealing in left and right bearing housing, that match with driving shaft and driven shaft periphery respectively and isolate, described left and right bearing housing is respectively arranged with lubricating cup with the corresponding position of rolling bearing; The axle stretch end that described driving shaft and driven shaft are positioned at bonnet is respectively arranged with an intermeshing synchromesh gear, and described bonnet is provided with lubricating cup; The power intake of described driving shaft extend out to the outside of protecgulum by the oil sealing that protecgulum is arranged, one end that driven shaft is positioned at protecgulum terminates in protecgulum chamber.
Synchromesh gear described in the utility model holds out against on driving shaft and driven shaft respectively by locking nut.
Pump housing inwall described in the utility model is provided with lining.
Principle of the present utility model and beneficial effect are: the utility model gear pump adopts a pair synchromesh gear drive pump gear, by adjusting the fit up gap of synchromesh gear, ensure that pump gear pair does not contact in the course of the work all the time.Being placed in by bearing outside gear pump body adopts grease lubrication not rely on pumped medium to lubricate.This structure successfully avoids the existence of friction pair in the pump housing, do not have friction pair then without the need to forming lubricant film, thus can in order to carry non-viscous fluid body medium.
