Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model specific embodiment bidirectional load type completely fills roller bearing；
Fig. 2 is part A partial enlarged view in Fig. 1；
Fig. 3 is this utility model specific embodiment clip spring structure schematic diagram.
Detailed description of the invention
Seeing accompanying drawing 1 to accompanying drawing 3, disclosed in this utility model, a kind of bidirectional load type completely fills roller bearing, includes axle
Bearing outer-ring 1 and bearing inner race 2, the inner periphery of bearing outer ring 1 is provided with outer ring raceway 11, the outer circumference surface of bearing inner race 2 sets
Having bear inner ring grooved railway 21, outer ring raceway 11 and bear inner ring grooved railway 21 corresponding matching to be formed guides the steel ball of steel ball to guide raceway, and steel ball draws
It is filled with steel ball 3 in full dress mode in guide roll road, bearing outer ring 1 and bearing inner race 2 is provided with and loads steel ball guiding for steel ball
Fill out segment mouth 12,22 in raceway, guide the axial both sides of raceway to be equipped with back-up ring 4, in bearing outer ring 1 at described steel ball
Periphery is provided with the back-up ring of U-shaped and fixes groove 13, and the outer circumference surface of bearing inner race 2 is provided with seal groove 23, the external diameter end of back-up ring 4
Being fixedly mounted on back-up ring and fix in groove 13, the inner-diameter end of back-up ring 4 seals in stretching into seal groove 23 and coordinates, described in fill out segment mouth 12,
The exterior side port of 22 blocks through back-up ring 4.Bearing uses fills out the design of segment mouth, conveniently with full between bearing outer ring and bearing inner race
Dress formula loads steel ball, it is ensured that bearing capacity, designs back-up ring at the axial two ends of full dress roller type bearing simultaneously, and on the one hand back-up ring will
Filling out segment mouth to block, bearing outer ring can be made to bear certain axial force, on the other hand, back-up ring plays sealing effectiveness, extending shaft
The service life held.
It is fixing that its guide ring can use grasswort to press-fit, but it exists structure complexity, and processing is inconvenient and installs the defects such as inconvenient,
Therefore, being installed with opening jump ring 5 in described back-up ring fixes groove 13, described opening jump ring 5 is located at the axially external of back-up ring 4, gear
Axially external of circle 4 and opening jump ring 5 counter stopper.Opening jump ring 5 is the circular of non-closed, and during installation, opening part closes
Closing, external diameter diminishes, and to facilitate the back-up ring loading outer ring to fix in groove, after being housed to, opening part opens, and external diameter becomes big, blocks completely
In back-up ring fixes groove, inner side and sealing ring are adjacent to backstop；And preferentially use, the opening 51 of described opening jump ring 5 is deviation
The angular cut in opening jump ring 5 center of circle so that even if opening jump ring is in the presence of opening, it is in the circumferential to back-up ring still
Forming continuous print counter stopper, opening jump ring is reliable with the counter stopper of back-up ring.
Wherein, described back-up ring fixes the axially outer side of groove 13 from external diameter end to inclining that inner-diameter end ecto-entad is formed slopely
Inclined-plane 131, opening jump ring 4 is supported in described inclined plane 131.So back-up ring fixes the outside employing inclined plane design of groove, side
Just jump ring loads, and after jump ring proceeds to, slips into along inclined plane, can support conflict by the more reliable axial end with back-up ring so that gear
Circle fixed installation is solid and reliable.
It addition, back-up ring fixes groove 13 and seal groove 23 degree of depth is all higher than or deep equal to filling out the exterior side port of segment mouth 11,21
Degree.The axially inner side wall of described seal groove 23 is slope 231, and the inner-diameter end of back-up ring 4 coordinates with slope 231 Interference contact.
Described seal groove 23 is U-shaped groove, the axially external convex edge 232 with radial protrusion of corresponding described seal groove 23.Above-mentioned
Design, it is possible to ensure that bearing is carried out good sealing effectiveness by back-up ring, improve the sealing property of bearing.
