Abstract
The utility model discloses a sealing connection structure of a box body and a box cover of a speed reducing box. The sealing connection structure comprises a first connecting hole (7), a second connecting hole (2) and a connecting element (1), wherein the first connecting hole (7) is arranged on the box body (6), the second connecting hole (2) is arranged on the box cover (3) and corresponds to the first connecting hole (7), and the connecting element (1) penetrates through the first connecting hole and the second connecting hole for connecting and fixing the box body and the box cover. The sealing connection structure is characterized in that a rubber gasket (4) is arranged between the first connecting hole (7) and the second connecting hole (2). The rubber gasket is arranged between the first connecting hole and the second connecting hole, the anti-leakage sealing inside the speed reducing box is realized, even when partial oil drips seep through the rubber gasket, no high-speed-flowing air in the speed reducing box exists in the inner side of the rubber gasket to generate pressure, oil drips cannot have sufficient motive power for passing through the first connecting hole to flow onto the box cover, and the anti-seepage effect is effectively reached.
Description
Technical field
The utility model relates to a kind of speed reducer casing and the case lid structure that is tightly connected.
Background technique
Speed reducer is a speed-regulating function device of motor, and a large amount of lubricant oil are being filled in speed reducer inside, for inter-agency interaction provides a good lubricated environment.Connection hole between speed reducer casing and case lid has been easy to oil seepage; At present in order to prevent its oil impregnate; The method that adopts is when casing is connected with case lid; Attachment hole oral area in case lid when on case lid, inserting link is placed a rubber washer, but poor effect still has lubricant oil and oozes out from packing ring and case lid contacting point.
The model utility content
The technical problem that the present invention will solve provides a kind of speed reducer casing and the case lid structure that is tightly connected, and can effectively prevent its oil impregnate.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is a kind of speed reducer casing and the case lid structure that is tightly connected; A kind of speed reducer casing and the case lid structure that is tightly connected; Comprise the attachment hole I that is located on the casing and be located at attachment hole II corresponding on the case lid, and pass attachment hole I and with attachment hole II casing is connected with case lid and is fixedly coupled part, be provided with rubber washer between said attachment hole I and the attachment hole II with attachment hole I.In the utility model rubber washer is located between attachment hole I and the attachment hole II; Realized carrying out leakproof seal in speed reducer inside; Even part oil droplet infiltrate rubber washer is arranged like this; But do not have swiftly flowing air generation pressure in the speed reducer in the rubber washer inboard, oil droplet does not have enough power yet and flows on the case lid through attachment hole I, has effectively reached the effect of leakage proof.
Preferably, said attachment hole I goes up the annular groove that the oral area that is connected with attachment hole II is provided with the location rubber washer, and the height of annular groove is less than the thickness of rubber washer.Establish annular groove at the orifice part of attachment hole I and place rubber washer, both be convenient to install, can rubber washer be positioned in the annular groove again, guarantee the sealing effect of the stable performance of rubber washer the linkage structure of casing and case lid.
Preferably, said rubber washer is provided with at least one.According to the one or more rubber washer of an amount of placement of the gap length situation between casing and case lid, can reach better sealing effect.
Preferably, said link is a bolt, and said attachment hole I is a tapped hole, and bolt cooperates with tapped hole.Worm structure is connected firmly, and easy to operate, and worm structure self also has sealing function.
The beneficial effect of the utility model is: rubber washer is located between attachment hole I and the attachment hole II; Be implemented in speed reducer inside and carry out leakproof seal; Even part oil droplet infiltrate rubber washer is arranged; But do not have swiftly flowing air generation pressure in the speed reducer in the rubber washer inboard, oil droplet does not have enough power yet and flows on the case lid through attachment hole I, has effectively reached the effect of leakage proof.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the enlarged view of I among Fig. 1.
Embodiment
A kind of embodiment's of the utility model as depicted in figs. 1 and 2 structural representation; Said a kind of speed reducer casing and the case lid structure that is tightly connected; Comprise the attachment hole I that is located on the casing 67 and be located on the case lid attachment hole II 2 corresponding, and pass attachment hole I and with attachment hole II casing is connected with case lid and is fixedly coupled part 1, be provided with rubber washer 4 between said attachment hole I and the attachment hole II with attachment hole I 7; Link is connected completion to the casing of gearbox with case lid after; Rubber washer is stuck in the position between attachment hole I and the attachment hole II, and is enclosed within the periphery of link, with the inside and outside spaced of gearbox.
As shown in Figure 2, in the utility model, said attachment hole I goes up the annular groove that the oral area that is connected with attachment hole II is provided with the location rubber washer; The height of annular groove is less than the thickness of rubber washer; Rubber washer is inserted in the annular groove, covers case lid, is connected casing with case lid fixing then.
In the present embodiment, said rubber washer 4 is provided with one.
In the present embodiment, said link 1 is a bolt, and said attachment hole I is a tapped hole, and bolt cooperates with tapped hole.With worm structure case lid and casing are linked together, be threaded and self bringing into play seal action.Said rubber washer also can be to be provided with more than one.
Except that the foregoing description; Said linkage structure also can be that bolt cooperates realization to be connected fastening with case lid to casing with nut; Be processed as through hole or tapped hole to the attachment hole on casing and the case lid this moment, between casing and case lid and bolt and nut cooperation place placement rubber washer; Can also be that other can effectively be connected casing and are fixedly coupled structure with case lid.Said rubber washer also can be to be provided with more than one.
Except that above-mentioned preferred embodiment; The utility model also has other mode of execution; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
