Abstract

The utility model discloses a bearing cover which comprises a cover body. The cover body comprises a bearing hole and a plurality of connecting holes; the cover body is provided with a sealing groove along the outer circumferential side of the bearing hole; and a sealing gasket is fitted in the sealing groove. The bearing cover has the benefit that as the sealing groove and the sealing gasket which can be fitted with each other are arranged on the bearing cover, external dust impurities can be prevented from entering a bearing and thus the normal operation of the bearing can be ensured.

Description

Bearing cap

Technical field

The utility model belongs to field of mechanical technique, is specifically related to a kind of bearing cap.

Background technique

In the using process of large size bearing machinery; in order to guarantee the good operation of bearing; usually need to protect extraneous dust impurity not enter in the bearing machinery by bearing cap is set, but the bearing cap of prior art often can not be accomplished better seal action by the reason of self structure.

The model utility content

The purpose of this utility model is to provide the automatically bearing cap of draining.

For realizing above-mentioned model utility purpose, a kind of bearing cap that the utility model provides, this bearing cap comprises:

Lid, described lid comprise bearing hole and some attachment holes;

Wherein, described lid is provided with seal groove along the outer circumferential sides of described bearing hole, is combined with sealing gasket in the described seal groove.

As further improvement of the utility model, also comprise the draining hole that arranges with described attachment hole interval on the described lid.

As further improvement of the utility model, described draining hole equates to the distance at the center of described bearing hole.

As further improvement of the utility model, the quantity in described draining hole is set to six.

As further improvement of the utility model, the material of described sealing gasket comprises rubber or plastic cement or silica gel or aforesaid combination.

Compared with prior art, seal groove and the sealing gasket of the utility model by cooperating bearing cap setting can be protected and not fill in extraneous dust impurity in the bearing, guarantees the normal operation of bearing.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the utility model bearing cap;

Fig. 2 is the A-A direction sectional view of the utility model bearing cap among Fig. 1.

Embodiment

Below with reference to embodiment shown in the drawings the utility model is described in detail.But these mode of executions do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these mode of executions, method or the function all is included in the protection domain of the present utility model.

Ginseng Fig. 1 is the structural representation of bearing cap 10 of the present utility model, and in the present embodiment, this bearing cap 10 comprises the body profile by lid 11 definition.

Comprise bearing hole 12 and some attachment holes 13 on the lid 11.Bearing hole 12 is used for passing for bearing, and in the present embodiment, bearing hole 12 can for example be arranged at the center position of lid 11.Attachment hole 13 is used for passing for link, so that bearing cap 10 is connected with the exterior mechanical parts.

Cooperation is with reference to Fig. 2, also comprise the draining hole 14 that arranges with attachment hole 13 intervals on the lid 11, this draining hole 14 is passed through broad ways and is run through lid 11, in the present embodiment, draining hole 14 is connected with the cavity of bearing hole 12 all sides in fact, when having unnecessary lubricant oil in the bearing, can drain into the external world by this draining hole 14.

As known to persons of ordinary skill in the art, bearing hole 12 places get the lubricant oil meeting so that the temperature during bearing working raises, and heat is difficult for leaving, and so can increase the weight of bearing may be because the damage that the temperature rising causes.By draining hole 14 is set, unnecessary lubricant oil in time can be discharged, ensured the work safety of equipment.

Distinguishingly, the quantity in draining hole 14 is set to six, and this draining hole 14 is equal to the distance at the center of bearing hole 12, so to guarantee good draining effect.

As preferred embodiment, lid 11 is provided with seal groove 15 along the outer circumferential sides of bearing hole 12, is equipped with the sealing gasket (not shown) in sealing groove 15.By seal groove 15 and the sealing gasket that so is equipped with, can guarantee that extraneous dust, impurity do not enter in the bearing by bearing hole 12, guarantee that bearing preserves from.

In specific embodiment more, the material of sealing gasket can for example adopt and comprise rubber or plastic cement or silica gel or aforesaid combination, so to obtain good sealing effect.

Distinguishingly, the diameter of bearing hole 12 is 192 millimeters.

Distinguishingly, the diameter of seal groove 15 is 220 millimeters.

Of the present utility model by above-mentioned mode of execution; has following beneficial effect: by seal groove and the sealing gasket that can cooperate bearing cap setting; can protect and not fill in extraneous dust impurity in the bearing; guarantee the normal operation of bearing; and with respect to traditional bearing cap that sealing gasket is not set; its sealing effect is better, can the stricter Environmental Conditions of adaption demand.

Be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.

Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
