An end surface of the side plate is coated with a wear-resistant coating. The circumferential local asymmetrical side plate for the gear oil pump provided by the utility model has the advantages that force balance of gears can be realized, carrying capacity and impact resistance of the gear oil pump can be increased, and a starting torque of the gear oil pump and heat generated by a friction pair between the gear and the side plate can be reduced.
Description
Technical field
The utility model relates to a kind of side plate, and the gear oil pump of the asymmetric formula in especially a kind of circumferential part is used side plate.
Background technique
The gear oil pump of using in underground work does not allow to adopt aluminum alloy material to make, and the aluminium, the magnesium dust that inevitably produce when preventing gear oil pump work cause accident of mine disaster.In the prior art, be with side plate on the gear shaft of duplicate gear oil pump, the gear end faces of both sides respectively has a side plate, and gear face cooperatively interacts with the mode that face contacts with the side plate side.Existing side plate all is axial and radial symmetric formula, and the processing of activation and coating is not carried out on the surface, when gear oil pump bears pressure and impacts; Strength of gear is uneven, and the suffered radial force of gear is bigger, and side plate is yielding, wearing and tearing; Cause gear oil pump to lose efficacy, influence gear oil pump working life.
The model utility content
The utility model is the deficiency that exists in the above-mentioned prior art for avoiding, and provides the gear oil pump of the asymmetric formula in a kind of circumferential part to use side plate, with the stress balance of realizing gear, the working life that increases gear oil pump.
The utility model adopts following technological scheme for the technical solution problem.
Circumferentially the gear oil pump of local asymmetric formula is used side plate, and its structural feature is on the thickness direction of said side plate, to be provided with the axis hole that penetrates said side plate; The outer circumferential face of said side plate upper end portion and underpart is the cylndrical surface, and left side, said cylndrical surface radius R 1 is bigger than right side, cylndrical surface radius R 2.
The gear oil pump of the asymmetric formula in circumferential part of the utility model also is with the structural feature of side plate:
Be coated with wear resistant coating on the said side plate end faces of both sides, the thickness of said wear resistant coating is 0.02mm～0.04mm.
Compared with present technology, the utility model beneficial effect is embodied in:
The side plate of the utility model, side plate adopt circumferentially local asymmetric formula structure, are guaranteeing that fully low pressure area scrapes under the situation of shell sealing; Enlarge the zone of high pressure of gear oil pump to greatest extent, realized the stress balance of gear, reduced the radial hydraulic pressure that gear bore; Improve the carrying and the impact resistance of gear oil pump, side plate adopts activation and coating to handle simultaneously, improves the formation ability of lubricant film; Reduce the friction factor between gear and the side plate; The heat that the starting torque of minimizing gear oil pump and gear and side sheet room friction pair are produced, and have good heat-conductive characteristic, the high temperature of gear oil pump, high speed performance are improved; Increase the working life of gear oil pump, enhance product performance.
The side plate of the utility model; When being installed on the gear oil pump; Its end faces of both sides matches with gear face, has starting torque and the gear of the stress balance that can realize gear, the carrying that improves gear oil pump and impact resistance, minimizing gear oil pump and the advantages such as heat that the side sheet room friction pair is produced.

Embodiment
Referring to figure accompanying drawing 1～accompanying drawing 2, circumferentially the gear oil pump of local asymmetric formula is used side plate, on the thickness direction of said side plate, is provided with the axis hole 1 that penetrates said side plate; The outer circumferential face of said side plate upper end portion 2 and underpart 3 is cylndrical surface 4, and said cylndrical surface 4 left side radius Rs 1 are bigger than cylndrical surface 4 right side radius Rs 2.Wherein: R1 is
, and R2 is
.
Be coated with wear resistant coating on the said side plate end faces of both sides 5, the thickness of said wear resistant coating is 0.02mm～0.04mm.Cast iron duplicate gear oil pump adopts circumferentially local asymmetric formula structure with side plate, guaranteeing that fully low pressure area scrapes under the situation of shell sealing, has enlarged the zone of high pressure of gear oil pump to greatest extent; Significantly reduced the radial hydraulic pressure that gear bore; Thereby improved the working pressure of gear oil pump, side plate adopts activation and coating to handle simultaneously, and the thickness of coating is 0.02mm～0.04mm; Improved the formation ability of lubricant film; Reduced the friction factor between gear and the side plate widely, reduced starting torque and the gear of gear oil pump and the heat that the side sheet room friction pair is produced, and had good heat-conductive characteristic; High temperature, the high speed performance of gear oil pump are improved, and be greatly improved working life.
The Main Ingredients and Appearance of said anti-friction wear-resistant sprayfused coating is: molybdenum disulfide, graphite, teflon, curing agent, plasticizer and epoxy resin; The coating of preparation anti-friction wear-resistant sprayfused coating:
Powdery class material molybdenum disulfide, graphite, alumina powder, ptfe micropowder are put into batch mixer mix stirring 5-10 minute, make the powder that stirs, for use; Epoxy resin, curing agent, plasticizer are added organic solvent, put into another batch mixer and stirred 10-20 minute, stirring makes resin compound; Again powder that stirs and resin compound are put into lapping machine jointly, ground 10-20 minute, promptly make coating;
Said surperficial spraying method:
Adopt the air spraying mode to carry out the surface spraying, coating evenly is sprayed on the surface of the copper alloy layer of side plate with spray gun; Solidify then: be warming up to 80 ℃ of insulations 30 minutes, continue to be warming up to 120 ℃ of insulations 20 minutes, continue to be warming up to 140 ℃ of insulations 20 minutes, be warming up to 180 ℃ of insulations 60 minutes again, cool to room temperature at last with the furnace.
