Specific embodiment

Below in conjunction with the accompanying drawings, this utility model is described in further detail.

A kind of bearing locating snap ring black box, including inner ring 1, outer ring 2, rolling member 3, dust cap 4 and block piece 5；Described interior Circle 1 and outer ring 2 are all in circular and concentric setting, and rolling member 3 is located between inner ring 1 and outer ring 2；Described block piece 5 has Two pieces, it is divided into inner ring 1 both sides and mutually touches with inner ring 1；Described dust cap 4 is fixed on outer ring 2, and dust cap 4 extends internally, and prevents Dirt lid 4 the inner is embedded at block piece 5, and dust cap 4 and the setting of block piece 5 gap；Described block piece 5 includes cylinder gear 5a and annulus gear 5b；It is in the cylindric of hollow that described cylinder keeps off 5a；It is in the circular of hollow that described annulus keeps off 5b；Described annulus gear 5b is wholely set Keep off 5a side in cylinder；The cylinder of one block piece 5 keeps off 5a is threadeded with the cylinder gear 5a of another block piece 5.

The middle part of described outer ring 2 outer wall is provided with a ring internal channel；It is provided with a locating snap ring, locating snap ring is one in described internal channel Opening elastomeric element, locating snap ring includes all semicircular arc left half-turn 6 and right half-turn 7.

Described left half-turn 6 one end is hinged with right half-turn 7, and the other end is hinged with locating dowel 6a；Described right half-turn 7 one end and a left side Half-turn 6 is hinged, and the other end is equipped with screw 7a；Described locating dowel 6a is the cylinder of hollow, and is provided with cylinder inwall Female thread；Described screw 7a passes through and is arranged in right half-turn 7 one end；Described screw 7a be provided with external screw thread and with locating dowel 6a spiral shell Stricture of vagina connects.

When installing this locating snap ring, screw 7a can be around its axis rotation, and by rotary screw 7a, adjusting screw 7a screws in fixed The depth of position post 6a, thus adjust the radius of bearing locating snap ring so that this locating snap ring inwall can be fitted all the time bearing outer wall.Positioning Post 6a can rotate around pin joint, thus adapting to being spirally connected of different angles.

This locating snap ring, also includes anchor 8；The raised 6b of described left half-turn 6 one end semicircle shape, described right half-turn 7 one end sets It is equipped with the caulking groove 7b of semicircle shape；Described projection 6b is embedded at caulking groove 7b；Described anchor 8 is arranged in raised 6b and caulking groove 7b.

This locating snap ring is embedded at the structure of caulking groove 7b using raised 6b, can guarantee that left half-turn 6 and right half-turn 7 all the time same Horizontal plane, it is to avoid both axial dipole field, is conducive to the installation of locating snap ring, increased the intensity of locating snap ring, extends locating snap ring Service life.

This locating snap ring, also includes locating pin 9；The location hole 10 of insertion is laid with described left half-turn 6 and right half-turn 7；Institute The angle of cut stating location hole 10 with locating snap ring radius is 40 ° ~ 85 °；Described locating pin 9 is embedded at location hole 10, and the length of locating pin 9 Degree is more than the depth of location hole 10.

The setting of locating pin 9, is conducive to locating snap ring to play the effect of quick stop.Locating pin 9 is inserted in location hole 10, Locating pin 9 inwall touches bearing outer wall, thus fixing bearing.The direction of location hole 10 is obliquely installed, it is to avoid locating pin 9 vertically connects The countershaft impact manufactured of contact bearing and deformation.

The outer wall that described annulus keeps off 5b offers caulking groove 5c；The inner bending of described dust cap 4 is L-shaped；Dust cap 4 interior End be embedded at caulking groove 5c and with caulking groove 5c interval setting.

During installation, first the block piece 5 of side block piece 5 and opposite side is inserted in the mesopore of inner ring 1, the cylinder of a block piece 5 Gear 5a is threadeded with the cylinder gear 5a of another block piece 5, thus block piece 5 is fixed on inner ring 1.During work, block piece 5 is with inner ring 1 action.Two block pieces 5 are designed to threaded, are conducive to block piece 5 is installed on the inner ring 1 of different-thickness, increase product Versatility.Then dust cap 4 is positioned over the side of outer ring 2, and dust cap 4 the inner is embedded at caulking groove 5c, finally use screw Dust cap 4 is installed on outer ring 2.The inner L-shaped structure design of dust cap 4 is so that form labyrinth between dust cap 4 and block piece 5 Sealing structure, desirably prevents the seepage of lubricating oil and isolation sand and dust enter Bearing inner.

Therefore, this sealed bearings has good sealing property, dust cap 4 to inner ring 1 and outer ring 2 no frictionally damage, be easy to pacify Assembly and disassembly are unloaded.

This utility model is illustrated according to embodiment, and on the premise of without departing from present principles, this device can also be made Go out some deformation and improve.It should be pointed out that the technical scheme that the mode such as all employing equivalents or equivalent transformation is obtained, all fall In protection domain of the present utility model.
