By adopting technique scheme, realize the closure of openings to pocket hole, effectively prevent that lubricating grease from leaking outside, thereby reach, improve bearing lubrication performance, and this structure lower bearing keeps simple in structure, easy to process.
The utility model is further set to: described two bound edges are close being obliquely installed mutually from be connected one end with retainer body to sealing one end, and two bound edge Formation cross-sections are shaped as leg-of-mutton folder chamber.
By adopting technique scheme, two bound edges are to tilt to extend to form, two bound edges form triangular shaped, two bound edge elasticity butts are reliable and stable, and the sealing of formation is stable, improves the reliability that stops to lubricating grease, and bound edge is processed to form simple and convenient, and two bound edges form leg-of-mutton clamping chamber, retained bound edge effect of clasping to steel ball at pocket hole opening, improve the Assembly stability of steel ball.
The utility model is further set to: one end of the mutual butt of described two bound edge is all extended with guide edge along retainer axial direction, and the guide edge on two bound edges is mutually away from extending and form the steel ball assembling targeting port that oral area is large, bottom is little.
By adopting technique scheme, realize steel ball assembling needs, during assembling, steel ball is led, steel ball pushes along steel ball assembling targeting port, drive two bound edge deformation away from, the sealing that two bound edges form is opened, thereby guarantee that steel ball enters into pocket hole smoothly, facilitate the assembling of steel ball.
The utility model also provides a kind of weaving pinch roller bearing, include outer ring and mandrel, mandrel is located in outer ring, outer ring and mandrel are provided with the two circle raceways of arranging vertically, in two raceways of mandrel and outer ring, be respectively fitted with, lower steel ball group, upper steel ball group and lower steel ball group have included retainer, retainer includes annular retainer body, retainer body is provided with pocket hole, on retainer body, pocket hole has the opening packing into for steel ball to one end towards retainer body shaft, the pocket hole of the retainer of described upper steel ball group is opening down, it is characterized in that: the opening both sides that are positioned at pocket hole on the retainer body of described upper steel ball group are provided with bound edge, two bound edges form and can elasticity open the sealing of closing up with respect to the other end elasticity butt that is connected one end with retainer body.
Further be set to: described two bound edges are close being obliquely installed mutually from be connected one end with retainer body to sealing one end, and two bound edge Formation cross-sections are shaped as leg-of-mutton folder chamber.
Further be set to: one end of the mutual butt of described two bound edge is all extended with guide edge along retainer axial direction, the guide edge on two bound edges is mutually away from extending and form the steel ball assembling targeting port that oral area is large, bottom is little.
Weaving pinch roller bearing adopts vertically assembling, its steel ball adopts grease lubrication, on it, on the retainer of steel ball group, pocket hole opening is setting down, the retainer of upper steel ball group is adopted to bound edge design, effectively prevent flowing downward of grease, grease is played to good maintenance effect, improve the greasy property of bearing, improve bearing working life, the steel ball assembling targeting port that guide edge forms facilitates packing in pocket hole of steel ball.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation

Fig. 2 is the retainer structural representation of the existing weaving pinch roller of the utility model bearing;
Fig. 3 is the utility model specific embodiment weaving wheel pressing shaft bearing structure schematic diagram;
Fig. 4 is the upper steel ball group retainer structural representation of the utility model specific embodiment weaving pinch roller bearing.
Embodiment
Referring to accompanying drawing 4, the disclosed a kind of retainer 51 of the utility model, include annular retainer body 511, retainer body 511 is provided with pocket hole 512, on retainer body 511, pocket hole 512 has the opening packing into for steel ball towards the axial one end of retainer body 511, the opening both sides that are positioned at pocket hole 512 on described retainer body 511 are provided with bound edge 513, two bound edges 513 and form and can elasticity open the sealing 514 of closing up with respect to the other end elasticity butt that is connected one end with retainer body 511.Bound edge is realized the closure of openings to pocket hole, effectively prevents that lubricating grease from leaking outside, thereby reach, improves bearing lubrication performance, and this structure lower bearing keeps simple in structure, easy to process.
For further improving grease, keep effect, described two bound edges 513 are close being obliquely installed mutually from be connected one end with retainer body 511 to sealing 514 one end, and two bound edge 513 Formation cross-sections are shaped as leg-of-mutton folder chamber 515.Such two bound edges are to tilt to extend to form, two bound edges form triangular shaped, two bound edge elasticity butts are reliable and stable, the sealing forming is stable, the stop reliability of raising to lubricating grease, and bound edge is processed to form simple and conveniently, and two bound edges form leg-of-mutton clamping chamber, retain bound edge effect of clasping to steel ball at pocket hole opening, improved the Assembly stability of steel ball.Certainly as the feasible technological scheme of the utility model, two bound edges can be and vertically extend to form riser, and riser end radially extends to form baffle plate docking to a close side mutually and forms the sealing that opening can folding, and two bound edge Formation cross-sections are shaped as rectangle; But so not only structure relative complex, not compact, and the closed insecure problem of the sealing forming; Can also be, bound edge adopts designed arc-shaped appearance, and two bound edge Formation cross-sections form circular arc, but exists like this sealing closure forming unreliable, and two bound edges are not easy to open, and steel ball packs inconvenient defect etc. into; Therefore the utility model preferentially adopts the structural design of this specific embodiment.
Reliable for guaranteeing sealing enclosed elastic, guarantee that steel ball packs in pocket hole convenient simultaneously, the guide edge 516 that one end of described two bound edge 513 mutual butts is all extended with on guide edge 516, two bound edges 513 along retainer axial direction is mutually away from extending and form the steel ball assembling targeting port 517 that oral area is large, bottom is little.In steel ball when assembling,, steel ball pushes along steel ball assembling targeting port, guide edge drive two bound edge deformation away from, the sealing that two bound edges form is opened, thereby guarantees that steel ball enters into pocket hole smoothly, facilitates the assembling of steel ball.
As Fig. 3 and Fig. 4, a kind of weaving pinch roller bearing, include outer ring 1 and mandrel 2, mandrel 2 is located in outer ring 1, outer ring 1 and mandrel 2 are provided with the two circle raceways 3 of arranging vertically, outer ring 1 and the axial two-port of mandrel 2 are provided with seal ring 4, are respectively fitted with upper and lower steel ball group 5,6 in two raceways 3 of mandrel 2 and outer ring 1; Upper steel ball group 5 and lower steel ball group 6 have included retainer, retainer includes annular retainer body, retainer body is provided with pocket hole, on retainer body, pocket hole has the opening packing into for steel ball to one end towards retainer body shaft, the pocket hole of the retainer of described upper steel ball group is opening down, therefore, lubricating grease on the retainer of upper steel ball group in pocket hole is along with the bearing running of working for a long time, lubricating grease flows downward, cause steel ball and the raceway contact area of steel ball group on bearing to lack grease lubrication, thereby dry friction occurs and early failue.For addressing this problem, the retainer of upper steel ball group has been carried out to corresponding construction improvement, adopt the design of above-mentioned retainer, above-mentionedly retainer is carried out to detailed description, this is repeated no more.
