Abstract
The utility model discloses a continuous oil supply device. The side wall of an oil cup or oil tank filled with lubricating oil is connected with the side wall of a device needing the lubricating oil through a grooved screw rod; the screw rod is provided with a check ring of which the radial side wall is provided with a small hole; the head of the screw rod is submerged into the lubricating oil in the oil cup or oil tank; and the radial side wall hole of the check ring, a groove on the screw rod and a threaded engagement gap serve as oil channels. In the continuous oil supply device, the lubricating oil can flow into the device needing the lubricating oil through the threaded groove and the threaded engagement gap; the threaded engagement length is adjustable, namely the amount of the supplied oil can be changed; and when the threaded connection is fastened, external threads pre-tighten internal threads, so that the oil supply is stopped.
Description
Technical field
The utility model relates to oil supplying device, especially relates to a kind of continuous oil supply device.
Background technique
The continuous oil supply device is known in the art, and forms such as wick lubrication, drop lubrication, ring-oil, splash lubrication and pressures cycle be lubricated are arranged.Above-mentioned oil supplying device exists that fuel feeding is insufficient, cost is higher or operating conditions is had more requirement.
If directly on the screw rod that joins with the need lubricating fitting, slot, then lubricant oil enters through radial side cinclides, groove, the thread engagement gap of back-up ring needs lubricated device, simple in structure, and oil flows in the enclosed space groove does not have the danger of obstruction, and operating conditions such as speed, load, oil quality are had no special requirements: the thread engagement space changes, and can change fuel delivery; And threaded together, but fuel cut-off.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous oil supply device, changes the more continuous oil supply design of traditional problem, in the hope of obtaining simple, controlled continuous oil supply method, thereby improves the continuous lubrication effect, simplifies oil supplying device, reduces cost, and raises the efficiency.
The technical solution adopted in the utility model is:
The utility model adopts the screw rod of fluting to be connected between the sidewall of the sidewall of lubricating cup that fills lubricant oil or fuel tank and the device that needs lubricant oil, radial sidewalls is housed on the screw rod opens the back-up ring of aperture, and screw head is immersed in the lubricant oil in lubricating cup or the fuel tank, and the radial side cinclides of back-up ring, screw rod fluting and thread engagement gap location are oil duct.
The fluting of described screw rod is direct through groove or spiral chute.This spiral chute is opposite with the screw flight rotation direction.
The beneficial effect that the utlity model has is:
1, lubricant oil flows into the device that will lubricate from lubricating cup or fuel tank through radial side cinclides, fluting, the thread engagement gap of back-up ring, and is simple in structure.
2, oil flows in the enclosed space groove does not have the danger of obstruction substantially, and operating conditions such as speed, load, oil quality are had no special requirements, and the assurance fuel feeding is continuous.
3, adjusting screw rod pretightening force size can change the thread engagement gap, thereby changes fuel delivery, realizes that oil mass is adjustable; During shutdown, tighten screw rod, reach maximum pretightening force, fuel feeding stops, and control is simple, convenient.
4, this continuous oil supply device flow of lubricant oil channel is not the gravity that utilizes lubricant oil, and the capillary force of micro-gap comes continuous oil supply between internal and external threads but utilize, thereby can horizontal positioned, and the application is extensive.
Description of drawings
Fig. 1 is a continuous oil supply device overall structure schematic representation.
Fig. 2 is the A place thread engagement enlarged view among Fig. 1.
Fig. 3 is a direct through groove screw-rod structure schematic representation in the continuous oil supply device.
Fig. 4 is a continuous oil supply device reverse thread groove screw-rod structure schematic representation.
Among the figure: 1, lubricant oil; 2, Kai Cao screw rod; 3, back-up ring; 4, lubricating cup or fuel tank; 5, need lubricating fitting.
Embodiment
Below in conjunction with accompanying drawing and instantiation the utility model is further described.
As shown in Figure 1 and Figure 2, between the sidewall of the sidewall of lubricating cup that fills lubricant oil 1 or fuel tank 4 and the device 5 that needs lubricant oil, adopt the screw rod 2 of fluting to be connected, on the screw rod 2 of fluting the back-up ring 3 that radial sidewalls is opened aperture is housed, and screw head is immersed in the lubricant oil in lubricating cup or the fuel tank, and the radial side cinclides of back-up ring 3, screw rod fluting and thread engagement gap location are oil duct.
As shown in Figure 3, Figure 4, the fluting of described screw rod is direct through groove or spiral chute.When fluting was direct through groove, if the fluting threaded stem is M20mm, then the groove width scope was 0.1～1mm.When fluting was spiral chute, spiral chute was opposite with the screw flight rotation direction, and spiral fluted pitch generally can be 2～10 times of screw pitch.
Working principle of the present utility model is as follows:
The screw rod 2 of fluting joins lubricating cup or fuel tank 4 with the thread engagement form with needing lubricating fitting 5.Screw thread is not during pretension, lubricant oil 1 is by back-up ring 3 radial sidewalls apertures or enter directly that the screw thread fluting flows into the thread engagement gap on the screw rod 2 of fluting in lubricating cup or the fuel tank 4, enter next fluting then, lubricant oil utilizes capillary force to flow in micro-gap, so continuously, finally entering needs lubricating fitting 5, at this moment the fuel delivery maximum; When needing to reduce fuel feeding, apply the nut that pretightening force makes the screw rod 2 of fluting, back-up ring 3, the inwall of lubricating cup or fuel tank 4 contacts in twos, the radial sidewalls aperture of lubricant oil 1 by back-up ring 3 enters that the screw thread fluting flows into the thread engagement gap on the screw rod 2 of fluting in lubricating cup or the fuel tank 4, enter next fluting then, lubricant oil utilizes between micro-gap capillary force to flow in enclosed space, so continuously, finally entering needs lubricating fitting 5, this moment is because the effect of pretightening force, the screw rod 2 of described fluting and need lubricating fitting 5 internal thread thread engagement gap smaller can reduce fuel delivery; The same, make it less than current pretightening force if reduce pretightening force, thread pitch increases, and fuel delivery increases; During shutdown, with screw rod 2 pretensions of fluting, outside thread dieback internal thread, then fuel cut-off.So reach purpose a small amount of, adjustable, continuous oil supply.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
