The utility model discloses a stamping conducting zero-gap ball bearing, which comprises an inner ring, an outer ring, steel balls, a stamping sheath and rubber rings, wherein the outer ring is in a hemispherical surface shape, a plurality of steel balls are arranged between the outer ring and the inner ring, the rubber rings are positioned at two sides of the outer ring, the rubber rings, the outer ring and the inner ring are placed in the stamping sheath, the stamping sheath is used for fixing the rubber rings, the outer ring and the inner ring, the stamping conducting zero-gap ball bearing also comprises a conducting copper sheet, and the conducting copper sheet is arranged between the stamping sheath and the rubber rings. Because the conducting copper sheet is arranged between the rubber rings and the stamping sheath, the bearing conducting stability is improved, and the conducting reliability of the stamping conducting zero-gap ball bearing is much better than that of the conventional stamping conducting zero-gap ball bearing.
Description
Technical field
The utility model relates to technical field of bearings, is specifically related to a kind of punching press conduction zero clearance ball bearing.
Background technique
Existing conventional punching press zero clearance ball bearing generally includes inner ring, outer ring, steel ball, punching press overcoat and rubber ring.In order to guarantee that bearing satisfies the zero clearance requirement when working, rubber ring all has been installed in the existing bearing, utilize the resiliently deformable of rubber ring to realize radially zero clearance.Yet such as the restriction of above-mentioned this punching press zero clearance ball bearing owing to structure, its electric conductivity is relatively poor at present.There is the gap between its outer ring external diameter and punching press outer casing internal diameter, thus when electric current reaches the outer ring from inner ring by steel ball, because there are radial clearance in outer ring and outer inner room, thus the jiggly phenomenon of electric current can appear, and then affect the reliability of bearing conduction.
Summary of the invention
The utility model purpose is for the existing deficiency of prior art, and the reliable punching press of a kind of conduction zero clearance ball bearing is provided.
In order to solve these problems of the prior art, the technological scheme that the utility model provides is:
A kind of punching press conduction zero clearance ball bearing, it comprises inner ring, outer ring, steel ball, punching press overcoat and rubber ring, the outer ring becomes semi-sphere type, several steel balls are housed between outer ring and inner ring, rubber ring is positioned at the both sides of outer ring, and rubber ring, outer ring, inner ring place in the punching press overcoat, and the punching press overcoat is fixed the three, described punching press conduction zero clearance ball bearing also comprises conductive copper sheet, and described conductive copper sheet is located between punching press overcoat and the rubber ring.
Detailed technological scheme is: a kind of punching press conduction zero clearance ball bearing, it comprises inner ring, the outer ring, steel ball, punching press overcoat and rubber ring, the outer ring becomes semi-sphere type, several steel balls are housed between outer ring and inner ring, rubber ring is positioned at the both sides of outer ring, rubber ring, the outer ring, inner ring places in the punching press overcoat, the punching press overcoat is fixed the three, described punching press conduction zero clearance ball bearing also comprises conductive copper sheet, described conductive copper sheet is located between punching press overcoat and the rubber ring, radially the position is between rubber ring external diameter and punching press outer casing internal diameter for described conductive copper sheet, and the bi-side of conductive copper sheet contact with punching press overcoat and semi-sphere type outer ring respectively.
Further, described conductive copper sheet can be independent part, also can be attached on the rubber ring, makes an integral body with rubber ring.
Than solution of the prior art, the utility model advantage is:
1. the described punching press of the utility model conduction zero clearance ball bearing, because inner room is provided with conductive copper sheet outside rubber ring and punching press, improved the stability of bearing conduction, thereby conduction reliability of the present utility model is better than conventional punching press conduction zero clearance ball bearing; By comparative trial, the utility model is compared existing conventional punching press zero clearance ball bearing, and it has conducted electricity Reliability Enhancement more than 5 times;
2. this punching press conduction described in the utility model zero clearance ball bearing, simple in structure, convenient manufacturing process is easily gone, and cost of production is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the monomer structure schematic representation of conductive copper sheet among the utility model embodiment;
Fig. 3 is the integrative-structure schematic representation of conductive copper sheet and rubber ring among the utility model embodiment;

Wherein: 1 outer ring; 2 inner rings; 3 punching press overcoats; 6 conductive copper sheets, 61 conductive copper sheet sides, 4 steel balls, 5 rubber outer rings.
Embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiments are not limited to limit the scope of the invention for explanation the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment:
The described punching press of present embodiment conduction zero clearance ball bearing, its overall structure as shown in Figure 1, it mainly comprises outer ring 1, inner ring 2, punching press overcoat 3, some steel balls 4, rubber ring 5 and conductive copper sheet 6.Steel ball 4 is between outer ring 1 and inner ring 2, and rubber ring 5 is positioned at the both sides of two hemisphere type outer rings 1, and places within the punching press overcoat 3 with outer ring 1, steel ball 4, by carrying out behind punching press overcoat 3 rollings axially with radially fixing.
Described conductive copper sheet 6 radially position and 61 contacts with punching press overcoat 3 and semi-sphere type outer ring 1 respectively in bi-side between rubber ring 5 external diameters and punching press overcoat 3 internal diameters.Conductive copper sheet 6 can be independent individuality (as shown in Figure 2), also can be attached to (as shown in Figure 3 and Figure 4) on the rubber ring 5, makes an integral body.
The utility model as the prior art, punching press overcoat 3 usefulness bearing supports or similar supporter are fixed, and inner ring 2 is coaxial fixing when concrete the use; It is when energising, electric current flows to inner ring 2 from input shaft, flows to the outer ring 1 of semi-sphere type by the roller 4 that contacts with inner ring 2, again by reaching bearing support with conductive copper sheet 6 that outer ring 1 contacts with punching press overcoat 3, form stable voltage loop, guaranteed the electric conductivity of bearing.By comparative trial, the utility model is compared existing conventional punching press conducting sphere bearing, and it has conducted electricity Reliability Enhancement more than 5 times.
Above-mentioned example only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalent transformations that Spirit Essence is done according to the present invention or modification all should be encompassed within protection scope of the present invention.
