Abstract
The utility model relates to a low-noise inside-gearing cycloid oil pump, which includes a front pump cover, a rear pump cover, a middle plate, a flange, a mandrel, an inner rotor and an outer rotor, wherein the meshed outer and inner rotors are arranged in the middle plate; the inner rotor is connected with the mandrel through a flat key; and a seal ring is arranged at the part where the flange is in sleeve joint with the mandrel. The low-noise inside-gearing cycloid oil pump is attractive in appearance, convenient to machine, low in manufacturing cost, excellent in sealing performance, wear resistant and less prone to oil leak.
Description
Technical field
The utility model relates to a kind of Swing line oil pump, engagement Swing line oil pump in particularly a kind of low noise.
Background technique
Swing line oil pump is the conversion equipment that mechanical energy is converted into the hydraulic pressure ability, is widely used in the hydraulic system of lathe, engineering machinery, as the power source of hydraulic system.The general ovalize of existing Swing line oil pump profile needs casting to form, and processing is inconvenient, and cost of production is high, and the closed performance of axle is bad, uses the easy abrasion leakage of oil for a long time.
Summary of the invention
The purpose of the utility model is to overcome the problems referred to above, has proposed the interior Swing line oil pump that meshes of a kind of low noise simple in structure, easy to process, good seal performance.
In order to achieve the above object, the technological scheme of the utility model employing is:
The engagement Swing line oil pump comprises the pump cover that is socketed on successively on the axle, middle sheet, rear pump cover, flange in a kind of low noise, is provided with in the middle sheet to be external rotor and the internal rotor that meshes shape, and internal rotor is connected with axle through flat key, and flange and axle socket place are provided with seal ring.
Engagement Swing line oil pump profile is rounded in said a kind of low noise.
Engagement shape in said external rotor and internal rotor are.
Compared with prior art, the beneficial effect of the utility model is:
The utility model profile is rounded, but turnning and milling process, beautiful shape, easy to process, reduced cost of production; Be provided with seal ring in the flange, this sealing structure performance is good, wear-resistant and not easy oil leakage.
Description of drawings
Accompanying drawing is the structural representation of the utility model;
Among the figure: rear pump cover 1, middle sheet 2, external rotor 3, internal rotor 4, front pump cover 5, seal ring 6, flange 7, axle 8, filler opening 9, oil outlet 10.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Engagement Swing line oil pump in a kind of low noise; Mainly comprise rear pump cover 1, middle sheet 2, external rotor 3, internal rotor 4, front pump cover 5, seal ring 6, flange 7 and axle 8; Rear pump cover 1 is provided with filler opening 9 and oil outlet 10, is provided with the external rotor 3 and internal rotor 4 of engagement shape in being in the middle sheet 2, and internal rotor is connected with axle 8 through flat key; Rear pump cover, middle sheet, front pump cover 5 and flange 7 are socketed on the axle 8 and are connected fixingly through screw, and flange and axle socket place are provided with seal ring.
