Abstract
The utility model discloses a DGBB (Deep Groove Ball Bearing) with rolling cross grain grooves. The DGBB comprises an inner ring, an outer ring, a dustproof cover and a plurality of steel balls, wherein the axial length of the inner ring is bigger than that of the outer ring; the grooves are respectively formed on the inner surface of the inner ring and the outer surface of the outer ring; the steel balls are clamped in the grooves between the inner and the outer rings; two half cages are respectively mounted on the two sides of each steel ball; clamping grooves are respectively formed on the two sides of each groove of the outer ring; the dustproof cover is covered on the half cages, and is clamped in a clamping groove on the inner surface of the outer ring; and a spring ring is mounted between the dustproof cover and the clamping groove. The dustproof cover provided by the utility model has good sealing property and low probability of falling off.
Description
Technical field
The utility model relates to a kind of deep groove ball bearing that has roll extrusion band groove.
Background technique
Structurally each lasso of deep groove ball bearing all has 1/3rd the continuous ditch type raceway that cross section is approximately the equatorial circle girth of ball.Deep groove ball bearing is mainly used in and bears radial load, also can bear certain thrust load.When the radial internal clearance of bearing increases, have the character of angular contact ball bearing, can bear the thrust load of both direction alternation.Compare with other measure-alike types of bearings, such pivot friction coefficient is little, and limit speed is high, and precision is high, the bearing type of first-selection when being user's type selecting.Deep groove ball bearing is simple in structure, and is easy to use, is that lots of production is maximum, one type of imported bearing that application area is the widest.Exist the mounting type of dust cover to exist installation insecure in the existing technology, cause dust to enter into and cause shorten working life on the steel ball between the Internal and external cycle.
The model utility content
The utility model provides the deep groove ball bearing that has roll extrusion band groove of a kind of dust cover good seal performance, difficult drop-off.
The utility model technical solution problem provides following scheme:
A kind of deep groove ball bearing that has roll extrusion band groove; Comprise inner ring, outer ring, dust cover and several steel balls, the axial length of said inner ring is longer than the outer ring, and said inner surface and inner ring outer surface are respectively equipped with groove; Said steel ball is fastened in the groove between the inside and outside circle; Said steel ball both sides are separately installed with the two halves retainer, and the groove both sides of said outer ring are established draw-in groove respectively, and said half keeps being covered with dust cover; Said dust cover is fastened in the draw-in groove of inner surface, between said dust cover and the draw-in groove spring ring is installed.
The surface of said outer ring is provided with mounting groove, and said mounting groove bottom is provided with band.
The utility model is when assembling; Dust cover is installed in the draw-in groove set on the outer ring, in the space between outer ring and the draw-in groove spring ring is installed, like this when dust cover is installed on the outer ring; Have the elastic force effect between spring and the dust cover, like this than between the clamping sealing to get well a lot.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of deep groove ball bearing that has roll extrusion band groove comprises inner ring 1, outer ring 2, dust cover 3 and several steel balls 4; The axial length of said inner ring 1 is longer than outer ring 2; Said outer ring 2 internal surfaces and inner ring 1 outer surface are respectively equipped with groove 5,6, and said steel ball 4 is fastened in inside and outside circle 1, the groove between 25,6, and said steel ball 4 both sides are separately installed with two halves retainer 7; Groove 5 both sides of said outer ring 2 are established draw-in groove 8 respectively; Said half retainer 7 is covered with dust cover 3, and said dust cover 3 is fastened in the draw-in groove 8 of outer ring 2 internal surfaces, between said dust cover 3 and the draw-in groove 8 spring ring 9 is installed; The surface of said outer ring 2 is provided with mounting groove 10, and said mounting groove 10 bottoms are provided with band.
