Abstract
The utility model discloses a kind of improved bearing inner-ring puller chucks, including a force bearing ring, the internal diameter of force bearing ring is greater than the outer diameter of bearing inner race, uniformly four adjustment bolts are arranged in interval in the radial ring body of force bearing ring, the inner end of adjustment bolt is spherical, the outboard end of adjustment bolt is square toes, and square toes Diagonal Dimension is less than the diameter of bolt.When work, by load ring set on bearing inner race, by turning adjustment bolt, so that bolt is tightly withstood the cambered surface of bearing inner race, so that driver-extractor chuck and bearing inner race be made to form one, then removed bearing inner race by tools such as jack.
Description
Technical field
The utility model relates to a kind of improved bearing inner-ring puller chucks.
Background technique
In maintenance process, the dismounting of bearing is a kind of extremely common work for enterprise.Current bearing extraction tool is mostly
Claw type driver-extractor, bearing complete for outer ring, claw type driver-extractor is more handy, it can preferably hook bearing outer ring side
Edge, so that bearing be removed from axis.But the bearing to fall off is damaged for outer ring, claw type driver-extractor is difficult to hook and have
The bearing inner race of cambered surface.Bearing inner race driver-extractor on the market is mostly two halves formula separate structure at present, although can be preferably real
The purpose that existing inner ring is removed, but its internal diameter is non-adjustable, and the bearing inner race for removing different inner diameters needs replacing different fixtures.
Summary of the invention
The purpose of this utility model is to provide a kind of improved bearing inner-ring puller chucks, can complete different sizes
The dismantlement work of bearing inner race.
The purpose of this utility model is achieved in that a kind of improved bearing inner-ring puller chuck, including one is held
Power ring, the internal diameter of force bearing ring are greater than the outer diameter of bearing inner race, are uniformly spaced in the radial ring body of force bearing ring and four adjustment are arranged
The inner end of bolt, adjustment bolt is spherical, and the outboard end of adjustment bolt is square toes, and it is straight that square toes Diagonal Dimension is less than bolt
Diameter.
The utility model driver-extractor is made of force bearing ring and adjustment bolt.Force bearing ring material is 45# steel, and thickness and width can basis
The magnitude of interference of the bearing inner race size and bearing to be removed installation determines；Adjustment bolt uses high-strength bolt, bolt head
It is processed into circular arc type, in favor of contacting very well with bearing inner race raceway.Uniformly distributed 4 perforation ring widthes has in force bearing ring cambered surface
The hole of screw thread.Adjustment bolt uses square head bolt, and square toes Diagonal Dimension is less than the diameter of bolt, in order to make leading edge deformation
Bolt can be exited from force bearing ring inner ring.When work, by load ring set on bearing inner race, by turning adjustment bolt, make
Bolt tightly withstands the cambered surface of bearing inner race, so that driver-extractor chuck and bearing inner race be made to form one, then passes through jack
Equal tools remove bearing inner race.
The invention can effectively carry out outer ring and damaged the bearing inner race that falls off removing, during being overhaul of the equipments
Very easy, practical bearing inner race removal tool.After the invention, kit may be implemented and remove plurality of specifications
Bearing inner race reduces service kit carrying amount.After the invention, other be mounted on an axle can also be removed and be not easy to remove
" set " type component.
Detailed description of the invention
Below in conjunction with attached drawing, the present invention will be further described.
Fig. 1 is the main view the schematic diagram of the section structure of the utility model；
Fig. 2 is the main view of the utility model force bearing ring；
Fig. 3 is the partial enlargement structural representation in the portion A in Fig. 1.
Specific embodiment
A kind of improved bearing inner-ring puller chuck, as shown in Figure 1, Figure 2, Figure 3 shows, including a force bearing ring 4, force bearing ring
4 internal diameter is greater than the outer diameter of bearing inner race 3, is uniformly spaced in the radial ring body of force bearing ring 4 and four adjustment bolts 2 are arranged, adjust
The inner end of whole bolt 2 is spherical, and the outboard end of adjustment bolt is square toes 1, and 1 Diagonal Dimension of square toes is less than 2 diameter of bolt.
