Abstract
The invention relates to a cam rotor pump with a bearing device provided with a forced lubrication mechanism. The cam rotor pump comprises a pump body (1), a bearing housing (2), a front cover (3), a driving shaft (5), a driven shaft (6), a driving rotor (51), a driving transmission gear (53), a driven rotor (61), a driven transmission gear (63), a thrust bearing (54), a thrust bearing (64), rolling bearings (55) and rolling bearings (65). The thrust bearing (54) and the rolling bearings (55) are installed between the driving shaft (5) and the bearing housing (2). The thrust bearing (64) and the rolling bearings (65) are installed between the driven shaft (6) and the bearing housing (2). The pump body (1) is in butt joint with the bearing housing (2) and the front cover (3). The cam rotor pump is characterized in that an eccentric wheel (7) is arranged on the driving shaft (5) and matched with a plunger rod (81) of a plunger pump (8) arranged on the inner cavity surface of the bearing housing (2); the plunger pump (8) is driven to work, and an oil outlet pipe opening (83') of the plunger pump (8) provides lubrication oil for lubricating the thrust bearing (64) and the rolling bearings (65) on the driven shaft (6). The problems that bearings of a driven shaft of a cam rotor pump are poor in lubrication effect, and consequently the service life is short and the amount of maintenance is high are solved.
Description
Technical field
What the present invention relates to is a kind of lobed rotor pump mainly for delivery of high viscosity medium, particularly a kind of lobed rotor pump of bearing means band pressure lubrication mechanism.
Background technique
Lobed rotor pump includes the pump housing 1, bearing housing 2, protecgulum 3, driving shaft 5, driven shaft 6, be arranged on the power rotor 51 on driving shaft, initiatively driving gear 53, be arranged on the driven rotor 61 on driven shaft, slave drive gear 63, be arranged on the thrust bearing 54 on driving shaft 5 and driven shaft 6 and between bearing housing 2 respectively, 64, rolling bearing 55, 65 and bearing gland 25, 26, be arranged on pump housing driving shaft axle sleeve 11a and pump housing driven shaft axle sleeve 11b and the mechanical seal device between driving shaft 5 and driven shaft 6 52 respectively, 62, be arranged on driving shaft 5 and the rolling bearing between driven shaft 6 and protecgulum 3 56 respectively, 66, the pump housing 1 and bearing housing 2, protecgulum 3 docks connection mutually.
Above-mentioned prior art does not have lubricating oil feed mechanism due to the thrust bearing 64 on the driven shaft 6 in bearing housing 2 and rolling bearing 65, it can only lean on slave drive gear 63 to splash with the oil lubrication in active driving gear 53 mating band, the lubricant oil of little amount prolongs driven shaft 6 and enters into thrust bearing 64 and 65, rolling bearing gives bearing lubrication, thrust bearing 64 and rolling bearing 65 lubrication effect of driven shaft 6 are bad, cause bearing temperature high, working life is short, increases maintenance cost.
Summary of the invention
The object of the invention is to improve for above-mentioned the deficiencies in the prior art, provide a kind of lobed rotor pump of bearing means band pressure lubrication mechanism, to improve the lubricating condition of thrust bearing on driven shaft and rolling bearing, high lubricating effect, long service life.
Lobed rotor pump of the present invention includes the pump housing 1, bearing housing 2, protecgulum 3, driving shaft 5, driven shaft 6, be arranged on the power rotor 51 on driving shaft, initiatively driving gear 53, be arranged on the driven rotor 61 on driven shaft, slave drive gear 63, be arranged on the thrust bearing 54 on driving shaft 5 and driven shaft 6 and between bearing housing 2 respectively, 64, rolling bearing 55, 65 and bearing gland 25, 26, be arranged on pump housing driving shaft axle sleeve 11a and pump housing driven shaft axle sleeve 11b and the mechanical seal device between driving shaft 5 and driven shaft 6 52 respectively, 62, be arranged on driving shaft 5 and the rolling bearing between driven shaft 6 and protecgulum 3 56 respectively, 66, the pump housing 1 and bearing housing 2, protecgulum 3 docks connection mutually, it is characterized in that outside active driving gear 53, driving shaft 5 being arranged being installed with eccentric wheel 7, to should fixedly mounting in the inner cavity surface of bearing housing 2 and be provided with plunger pump 8 by eccentric wheel 7, plunger rod 81 front end of plunger pump 8 contacts with the cylindrical of eccentric wheel 7 and coordinates, eccentric wheel 7 rotates with driving shaft 5 and drives plunger rod 81 to-and-fro motion of plunger pump 8 that plunger pump 8 is worked, the fuel-displaced mouth of pipe 83 ' of the oil outlet tube 83 on plunger pump 8 extend in driven shaft 6 bearing bore 20 of bearing housing 2, provides lubricant oil to lubricate to the thrust bearing 64 on driven shaft 6 and rolling bearing 65.
The present invention is rational in infrastructure, it is simple and convenient to manufacture, high lubricating effect, and what solve that lobed rotor pump driven shaft bearing causes because lubrication effect is bad makes the problem that the life-span is short, amount of maintenance is high.
