Abstract

The utility model discloses a hinge which comprises a rotating shaft and folders sleeved on the rotating shaft. An oil storage tank is arranged in the rotating shaft. An oil inlet of the oil storage tank is arranged in one end face of the rotating shaft and is connected with an oil cup. An oil outlet is further arranged in the rotating shaft and is communicated with the oil storage tank and the outer surface of the rotating shaft. The hinge has the advantages of solving the problems of friction and abrasion between the rotating shaft and the folders by aid of dedicated arrangement of an oil lubricating structure, and being small in friction and abrasion.

Description

A kind of hinge

Technical field

The utility model relates to the hinge technical field, particularly lubricated good hinge between a kind of rotating shaft and the folding.

Background technology

The comings and goings hinge that adopts on the equipment such as the door on the locomotive, window in use repeatedly breaks down, through checking and statistics, find that these fault main manifestations concentrate on the following aspects: one, the axis hole axiality substantial deviation in rotating shaft and the folding causes the rotation clamping stagnation; Two, when relative motion occurs, larger dry friction is arranged between the axis hole in rotating shaft and the folding, make the empty inner surface gross distortion of rotating shaft external surface and hinge pin, when serious, even rotating shaft is fractureed; Three, in the situation that serious vibration, rotating shaft may be jumped out folding, thereby the accident that causes door, window etc. to fall exists potential safety hazard.

The utility model content

Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of hinge, mainly solve the large problem of friction between rotating shaft and the folding.

The technical solution adopted in the utility model is such: a kind of hinge, comprise rotating shaft and socket folding thereon, in the described rotating shaft oil storage tank is set, the oil-in of oil storage tank is located at rotating shaft one end face and is connected with a lubricating cup, also be provided with oil outlet, described oil outlet is communicated with oil storage tank and rotating shaft external surface.Inject lubricant grease by lubricating cup in oil storage tank, then, lubricant grease flows out to the rotating shaft external surface by oil outlet and form oil layer between the axis hole of rotating shaft external surface and folding, plays lubrication.

As preferably, described rotating shaft has an end external surface of oil storage tank oil-in that the boss of annular is set, and the other end arranges screw, and is connected in the screw with screw thread the position of folding and rotating shaft is fixed.Axially-movable between folding and the rotating shaft is limited by boss and these two kinds of structures of screw screw at the rotating shaft two ends.

As preferably, between screw and rotating shaft end face, also overlap successively flexible packing ring and plain washer.Elastic washer is connected effect and is mainly played the buffering vibration impact force and screw is connected more stable with plain washer.

As preferably, the folding that is socketed in the described rotating shaft has more than two, and correspondingly, oil storage tank is provided with and the corresponding oil outlet of folding number, and these oil outlets are communicated with oil storage tanks and rotating shaft external surface and corresponding with each folding.Set out like this oilhole, guaranteed that two foldings can both be subject to good lubricating.

As preferably, be socketed with packing ring in the rotating shaft between per two adjacent foldings.Guaranteed that lubricant grease can not pollute whole hinge arrangement because of leakage.

In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: by the grease lubrication structure of special setting, solved the friction and wear problem between rotating shaft and the folding, frictional force is little, weares and teares also very little; The boss at rotating shaft two ends and bolt structure have effectively prevented the axially-movable between rotating shaft and the folding, and structure is safety and firmness more.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

Embodiment 1:

A kind of hinge, comprise rotating shaft 1 and socket folding 2 thereon, the described rotating shaft 1 interior oil storage tank 11 that arranges, the oil-in of oil storage tank 11 is located at rotating shaft 1 one end faces and is connected with a lubricating cup 6, also be provided with oil outlet 12, described oil outlet 12 is communicated with oil storage tank 11 and rotating shaft 1 external surface.

Described rotating shaft 1 has an end external surface of oil storage tank 11 oil-ins that the boss 13 of annular is set, and the other end arranges screw 14, and is threadedly connected to screw 14 interior positions with folding 2 and rotating shaft 1 with screw 3 and fixes.

Between screw 3 and rotating shaft 1 end face, also overlap successively flexible packing ring 4 and plain washer 5.

Embodiment 2:

As shown in Figure 1, 2, a kind of hinge, comprise rotating shaft 1 and socket folding 2 thereon, the described rotating shaft 1 interior oil storage tank 11 that arranges, the oil-in of oil storage tank 11 is located at rotating shaft 1 one end faces and is connected with a lubricating cup 6, also be provided with oil outlet 12, described oil outlet 12 is communicated with oil storage tank 11 and rotating shaft 1 external surface.

To oil storage tank 11 interior injection lubricant greases, then, when rotating between rotating shaft 1 and folding, lubricant grease flows out to rotating shaft 1 external surface by oil outlet 12 and form oil layer between the axis hole 21 of rotating shaft 1 external surface and folding 2, plays lubrication by lubricating cup 6.Folding 2 and on the concrete structure figure of axis hole 21 shown in Fig. 3,4.

In the present embodiment, described rotating shaft 1 has an end external surface of oil storage tank 11 oil-ins that the boss 13 of annular is set, and the other end arranges screw 14, and is threadedly connected to screw 14 interior positions with folding 2 and rotating shaft 1 with screw 3 and fixes.Shown in Fig. 5,6.

The folding 2 of socket has two in the described rotating shaft 1, and correspondingly, the length of oil storage tank 11 rotating shaft 1 in is greater than half of rotating shaft 1 length, and oil outlet 12 has two, separately correspondence a folding 2.Be socketed with packing ring in the rotating shaft 1 between described two foldings 2.As shown in Figure 1, 2.

Among above-mentioned two embodiment, folding 2 adopts the modes such as welding or bolt connection to make the flat position of folding 2 and hinged component affixed, and folding 2 component affixed with it are together rotated along rotating shaft.

The utility model can be according to the quality of hinged component, use industrial and mineral etc. that its physical dimension and self material are selected, and himself structural strength and rigidity are carried out proper fit.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
