Description
Technical Field
The utility model relates to a gear pump production technical field especially relates to a gear pump lubricating arrangement.
Background
Along with the development of industry, the application range of gear pump is wider and wider, and hydraulic gear pump is important power source mechanism in hydraulic system, and the occasion of application is different, and hydraulic gear pump relies on the working volume change that forms between pump cylinder and the meshing gear and removes to carry liquid or make its pressure boost rotary pump, and current gear pump is at the during operation, and the gear shaft rotates, produces the friction with the end cover easily, causes the product wearing and tearing.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a gear pump lubricating arrangement.
The utility model adopts the following technical scheme:
the utility model provides a gear pump lubricating arrangement, includes the gear pump end cover, be provided with two shaft holes on the gear pump end cover, be provided with lubricated portion in every shaft hole, lubricated portion includes a plurality of graphite blocks that set up along shaft hole circumference interval, every be provided with the carbon fiber piece between the graphite block, the carbon fiber piece with it is fixed through bonding between the graphite block, carbon fiber piece with still be provided with the amortization pad between the gear pump end cover, the amortization pad with graphite block, carbon fiber piece and it is fixed through bonding between the gear pump end cover.
Preferably, the sound-absorbing pad is formed by compounding a PV honeycomb plate and a regenerated fiber felt.
Preferably, a damping layer is further arranged between the silencing pad and the gear pump end cover.
Preferably, the shock absorbing layer is made of ethylene-vinyl acetate copolymer material.
The utility model has the advantages of it is following that the utility model discloses a gear pump lubricating arrangement is through setting up the graphite piece, and the graphite piece has self-lubricating function, can prevent that the gear pivot from producing wearing and tearing to the end cover, has still set up the amortization pad simultaneously for the gear pump has the amortization function.

Detailed Description
As shown in fig. 1-3, for the utility model discloses a gear pump lubricating arrangement, including gear pump end cover 1, be provided with two shaft holes 2 on the gear pump end cover 1, be provided with lubrication portion in every shaft hole 2, lubrication portion includes a plurality of graphite blocks 3 that set up along 2 circumference intervals in shaft hole, be provided with carbon fiber block 4 between every graphite block 3, it is fixed through bonding between carbon fiber block 4 and the graphite block 3, still be provided with amortization pad 5 between carbon fiber block 4 and the gear pump end cover 1, amortization pad 5 and graphite block 3, it is fixed through bonding between carbon fiber block 4 and the gear pump end cover 1.
Specifically, through setting up graphite block 3, graphite block 3 has self-lubricating function, can prevent that the during operation, gear shaft produce wearing and tearing to the end cover when rotating, and simultaneously, the special type fibre that the carbon fiber comprises carbon element has very high mechanical strength, has further strengthened the wearability of gear pump shaft hole 2 departments.
Further, the silencing pad 5 is formed by compounding a PVC cellular board 51 and a regenerated fiber felt 52, the cellular board 51 has sound insulation and suction functions and is made of a PVC material, the cellular board has good toughness, the regenerated fiber also has a sound insulation effect, and the sound insulation effect is further improved by compounding the cellular board 51 and the regenerated fiber.
In addition, a damping layer 6 is arranged between the silencing pad 5 and the gear pump end cover 1, and preferably, the damping layer 6 is made of an ethylene-vinyl acetate copolymer material, namely EVA, which has the advantages of good flexibility, shock resistance, skid resistance and strong pressure resistance, and improves the comprehensive performance of the gear pump end cover.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made on the basis of the present invention to solve the same technical problems and achieve the same technical effects are all covered by the protection scope of the present invention.
