Abstract
The utility model relates to a top roller bearing applicable for normal assembly of a structure of biserial six steel balls. The biserial six steel balls 1 with the diameter of Phi 4 mm are arranged in the top roller bearing. The line of centers of the boundary steel balls 1 is longer than the central line of a course 2. In the utility model, the difficulty that the <over-semi-diameter> assembly can not be achieved by normal assembly means is overcome. The mechanical performance of the utility model has the advantages of even abrasion, large loading capacity and assurance of the channel depth.
Description
One, technical field:
The utility model belongs to textile machinery accessories, is specifically related to six steel ball structure upper roller bearings of a kind of suitable conventional assembling biserial.
Two, background technique:
At present, the roller bearing of domestic production has two kinds of patterns, and a kind of is five of row, six Φ 4mm of row steel ball structure, and as Fig. 1, it is inhomogeneous to wear and tear during the drawback of this kind structure is to use, and influences yarn-spinning quality; Another kind is a biserial Φ 3.5mm steel ball structure, and as Fig. 2, the drawback of this kind structure is that bearing capacity is low.The upper roller bearing of these two kinds of patterns is short working life, and abrasion resistance properties is relatively poor.
Three, summary of the invention:
The technical problems to be solved in the utility model is: the wearing and tearing of solution upper roller bearing are inhomogeneous, increase the service life, and improve yarn-spinning quality.
The technical solution adopted in the utility model is: six steel ball structure upper roller bearings of a kind of suitable conventional assembling biserial, comprise steel ball 1, runway 2 is provided with the steel ball 1 of six Φ 4mm of biserial diameter in the upper roller bearing, steel ball 1 line of centres in border exceeds runway 2 center lines.
The utility model compared with prior art has following beneficial effect: overcome the domestic difficulty that can't use conventional assembling means to realize " super radius " assembling.The utility model mechanical property has advantages such as wearing and tearing are even, bearing capacity is big, assurance channel depth.
Four, description of drawings:
Fig. 1 is the upper roller bearing structural representation of five of row;
Fig. 2 is the upper roller bearing structural representation of six of biserials;
Fig. 3 is a structural representation of the present utility model.
Five, embodiment:
Six steel ball structure upper roller bearings of a kind of suitable conventional assembling biserial as shown in Figure 3, are provided with the steel ball 1 of six Φ 4mm of biserial diameter in it, steel ball 1 line of centres in border exceeds runway 2 center lines.Critical size: shell aperture Φ 16.2mm, the dark 0.4mm of raceway groove, the dark 0.2mm of casing groove, mandrel raceway groove end outside diameter Φ 9mm, the dark 0.4mm of raceway groove.
Claims (1)
1, six steel ball structure upper roller bearings of a kind of suitable conventional assembling biserial, comprise steel ball (1), runway (2) is characterized in that: be provided with the steel ball (1) of six Φ 4mm of biserial diameter in the upper roller bearing, border steel ball (1) line of centres exceeds runway (2) center line.
