Abstract
The utility model discloses a bearing box. A bearing cap (1), a lower cover (2), and a base (3) are formed through punching, the lower cover (2) is welded on the base (3), the outer side of the lowercover (2) is wrapped with a circle of sheet iron (6), the upper end surface of the sheet iron wrapped at lugs on the two sides of the lower cover (2) is lower than the upper end surface of the lugs, forming a rabbet structure, and the circular arc openings of the bearing cap (1) and the lower cover (2) are correspondingly buckled together to form a ring-shaped bearing mounting cavity (4) and a circular axle hole (5). All the parts in the bearing box is formed through punching via the board stretching, and the whole bearing box has good toughness, can bear the mechanical vibration, and has little possibility of fracture; and the efficiency of production and processing is higher, the material required by stamping parts is less, the cost is lower, and the weight is lighter, at the same time,the relative displacement of the bearing cap, the lower cover, and the base does not occur, and the combination is firm.
Description
Technical field
The utility model relates to a kind of bearing box, is used for the more durable bearing boxs of device installation bearing good toughness such as farming operation.
Background technique
General bearing box is made of bearing cap and bearing support at present, and bearing cap and bearing support are bolted to connection, and most bearing caps and bearing support all are the urib founding moulding.Elder generation's molten materials is done the material that film will dissolve again and is poured into, and the product that obtains also will be through the polishing moulding, production and processing is cumbersome, be installed in farm machinery when bearing box is used for farming operation, because the vibration of machinery, urib founding toughness is very easy to damage inadequately, fracture.Simultaneously whole bearing box casting all is that solid material consumption is many, and cost is also than higher, and bearing box weight is also heavier.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of toughness better, and the lower cover of bearing cap is in conjunction with firm bearing box.
The technical solution of the utility model is as follows: a kind of bearing box, bearing cap, lower cover and base are impact briquetting, lower cover is welded on the base, the middle part of described bearing cap and lower cover is a circular arc, these circular arc two ends are extended with journal stirrup, described bearing cap and lower cover cross section are the groove shape, all have mounting hole on the journal stirrup that extend at described bearing cap and lower cover two ends, its key is: the described lower cover outside is coated with a circle iron plate, the iron sheet upper-end surface that this journal stirrup place, lower cover both sides coats is lower than the journal stirrup upper-end surface and forms fixing structure, described bearing cap, lower cover circular arc opening snaps together relatively and forms annular bearing installation chamber and circular axis hole.Bearing cap and lower cover all are to utilize the sheet material back that stretches to form by same die stamping, and base also is stamped to form, and it is very simple and improved manufacturing efficiency then lower cover to be welded on the base whole processing.The lower cover outside is coated with a circle iron plate simultaneously, and iron plate covers the formation fixing structure for being welded on down, and bearing cap and lower cover fasten can not produce bigger relative displacement, in conjunction with close and firm, is installed in mechanically, can not produce bigger noise in the work.
Position over against the lower cover mounting hole on the above-mentioned base also has mounting hole, the central lines of mounting hole on the described bearing cap of this base, lower cover and the base.By bolt bearing cap, lower cover and base are fixed together, more infirm and stable than casting integrated bearing box at all.
The mounting hole place of above-mentioned base end face is welded with nut, the mounting hole central lines of this nut and base.Nut can be weldingly fixed on the base nut and be cascaded bearing cap, lower cover and base fixing from top to bottom.Head that also can nut is positioned at base, and nut is positioned at bearing cap mounting hole top.
Above-mentioned base becomes the circular arc proper mutually with the lower cover bottom with the downward spill in lower cover attachment portion.Base lower cover area of contact is bigger like this, and the welding back connects more firm.
Beneficial effect: each parts of the utility model all are by the moulding of sheet material stretching and punching, and whole bearing box good toughness is able to take the vibration of machinery, is not easy fracture; Production and processing efficient is higher, the stamping part material requested still less, cost is lower, weight is lighter, simultaneously bearing cap, lower cover and base can not produce relative displacement, in conjunction with firm.

Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, shown in Figure 2, a kind of bearing box of present embodiment is by bearing cap 1, lower cover 2 and base 3 are formed, bearing cap 1, lower cover 2 and base 3 are impact briquetting, lower cover 2 is welded on the base 3, the middle part of described bearing cap 1 and lower cover 2 is a circular arc, these circular arc two ends are extended with journal stirrup, described bearing cap 1 and lower cover 2 cross sections are the groove shape, all have mounting hole on the journal stirrup that extend at described bearing cap 1 and lower cover 2 two ends, position over against lower cover 2 mounting holes on the described base 3 also has mounting hole, the mounting hole place of described base 3 bottom surfaces is welded with nut 7, bearing cap 1, lower cover 2, the mounting hole central lines of base 3 and nut 7.Bolt is cascaded bearing cap 1, lower cover 2 and base 3 fixing from top to bottom successively.Described lower cover 2 outsides are coated with a circle iron plate 6, iron plate 6 is for being welded on the lower cover 2, the iron sheet upper-end surface that this journal stirrup place, lower cover 2 both sides coats is lower than the journal stirrup upper-end surface and forms fixing structure, and described bearing cap 1, lower cover 2 circular arc openings snap together relatively and form annular bearing installation chamber 4 and circular axis hole 5.State base 3 and become the circular arc proper mutually with lower cover 2 bottoms with the downward spill in lower cover 2 attachment portions.
