The utility model has a bearing seat and a box bottom seat of the bearing (4), the bearing seat is in a main body (2), the bottom seat has wall bodies (8a, 8b, 9a and 9b) which are hung from the part of the main body (2), the structure of an outer bottom seat of a quadrangular housing body is formed, the end of the wall body far away from the main body is assembled on a foundation, the parts of the wall bodies (10, 13 and 14) are arranged between the wall bodies (8a and 8b) opposite to the bottom seat (4), the parts of the wall bodies stretch between the end of the bottom seat intended to be assembled to the upper part of the foundation toward the upper part to the main body (2), and thereby, the rigidity of the bearing box is increased, and the twisted risk of the bearing seat during operation is reduced.
Description
The present invention relates to a kind of rolling of horizontal axis or bearing box of sliding bearing of containing, it has columnar built-in bearing support to admit the outer race of bearing, described bearing box has a bearing box base, and it is supporting described bearing support and is containing the device that it is fixed to the basis.
This class bearing box base spare is made the form of the homogeneous bulk of the parallel aspect with flat bottom at first, this means that they are very heavy, and in addition, Gu Ding basis needs an auxiliary surface through cutting with it.
So, take up the base portion of bearing box is made shell shape, just a kind of bearing box of die casting formula, its bearing support and tubular element join together, and tubular element is bearing in inside with open type and only has on the base element of outer supporting element of thin wall.This means that this bearing box only is located on the basis with the line contact form along its outer contour, be sure of that can not will the whole surface of base cutting of this kind contact is so that the bottom surface tight connecting of it and base element.Yet this class bearing box is very sensitive to high bearing load, because the tube body that joins together with bearing support is only partly being supported by thin-wall shell, it can cause bearing support distortion or dislocation.This also means the rigidity that reduces bearing box, and has reduced its bearing capacity thus.
The purpose of this invention is to provide a kind of bearing box, particularly a kind of bearing box with this class base element makes these problems can obtain to a great extent elimination.
The invention will be further described in an embodiment's shown in the drawings mode below.
Fig. 1 illustrates the side view of plain edition bearing box.
Fig. 2 is the perspective view by bearing box underside side of the present invention that tiltedly shows.
Fig. 3 is the planimetric map from the bottom surface of bearing box base portion.
Fig. 1 shows the side view of plain edition bearing box 1, and this bearing box comprises tubular body portion 2, and it has a built-in columnar pedestal, does not show in the drawings, and this cylindrical seats body and function is admitted the rolling or the sliding bearing of supporting axle 3.Tubular body portion 2 is supported by the tabular base portion 4 of rectangular base, and this base has fixed hole 5, by means of bolt 6 bearing box is fixed on the basis usually.
Fig. 2 shows the bearing box of being seen as from the perspective view of the bottom surface of base element 4 stravismus of the present invention, and the main body 2 that it has a bearing box is towards away from observer's direction.There is a rectangle outer contour 7 bottom surface of base element, but has scabbled at its four angles.
As seeing in the drawings, base element 4 is to be shelly and thin outer wall is arranged, thereby has reduced the weight of bearing box.The case surface of tubular body spare and the bottom plane of base element are that slot milling is separating in this wise, it is described case surface, it forms the outer cover of bearing support, when bearing box is loaded onto, it swells from base plane, thereby between basis and the described case surface and what forming described base element 4 is to have reserved the space of opening wide between the outer wall of rectangular profile line substantially.Away from bearing box main body 2 places, bearing box base 4 has two separating with the space vis-a-vis, long and narrow wall portion 8a, and 8b, its end and two short and narrow wall portion 9a, 9b links.There is a crossbeam wall 10 between vis-a-vis wall portion 8a and 8b, to stretch and the case surface of autonomous agent 2 extends wall portion 8a, 8b, 9a, the position of the bottom plane of 9b at the central position of base 4.This centre cross member wall 10 directly place bearing box main body 2 bearing support below, thereby thereby the rigidity that helps strengthening bearing box increased its bearing capacity to the basis.This centre cross member wall 10 also plays bearing from bearing box to the effect of the heat transfer on basis, thereby has reduced the operating temperature of bearing.In an illustrated embodiment, this centre cross member wall 10 has two fins 11,12 vis-a-vis, they from centre cross member wall 10 at extending longitudinally, this two fin has increased the surface of contact between the 5 bearing support positions, bottom surface of bearing box base, thereby more helps the heat transfer from the bearing box to the basis.
Near the short sidewall 9a of base element 4, the oval-shaped fixed hole of mentioning before 9b has 5 is used for bearing box is fixed to the basis.Be equipped with horizontal middle wall body 13 and 14 in these fixed hole 5 inboards towards centre cross member body of wall 10 very short distance.These horizontal middle wall body 13 and 14 stretch and extend from the top of base element its fixed pan downwards as central body of wall between long sidewall 8a and 8b.These horizontal middle wall body 13,14 will directly be passed to the basis from the retention force of fixing bolt 6 (see figure 1)s and this power of having no way of makes the danger of bearing support distortion or distortion.In addition, this horizontal middle wall body 13,14 will be strengthened the rigidity of bearing box base 4.
As previously mentioned at body of wall 8a, 8b, the angle between 9a and the 9b is cut and has been put down, and they are compared with outer wall spare bigger thickness.These angle parts can be provided with blind hole 15 (representing with imaginary circle) in Fig. 2.Guide finger of these blind hole 15 each receivabilities, these holes are gone up corresponding hole with the basis and are coincide.This class guide finger is convenient to reinstall bearing box after maintenance, and it also absorbs the shearing to the basis.
Description and the most handy die casting manufacturing of illustrated bearing box, its available different metal is made, and as cast iron, lead etc. also can be made of plastic.
Under bearing box occasion made of plastic, the metalwork of imbedding of available separation or particle are to strengthen bearing box and to improve its heat-transfer capability to the basis.
