Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the utility model, therefore it only shows the composition related with the utility model.
A kind of transmission shaft tapered roller bearing internal ring extracting tool as shown in Figure 1, 2, including：
Snap ring 1, endoporus are stepped hole, which includes taper hole, and taper hole big end has annular inner stopper 1-1, snap ring
1 lower end has male half coupling 1-2, and 1 upper end of snap ring is arranged with connecting screw hole 1-3, and snap ring 1 is divided into two along axis after subdivision,
The whole circle conical roller 1-4 being enclosed in after 1 pairing of snap ring being divided into two by taper hole on transmission shaft tapered roller bearing internal ring
Periphery, while 1 annular inner stopper 1-1 of snap ring fastens with whole circle conical roller 1-4 big ends；
Body 2, sliding sleeve support on snap ring 1, and by 1 male half coupling 1-2 of snap ring；
Pulling plate 3 is arranged on 1 top of snap ring, and 3 middle part of pulling plate is equipped with installation screw, and installation screw both sides are arranged with peace
Fill hole；
A pair of of studs 4, snap ring 1 are connected by two studs 4 with pulling plate 3, and 4 lower end of studs screws in card
In connecting screw hole 1-3 on ring 1,4 upper end of studs is fixedly connected by 3 mounting hole of pulling plate and a pair of of nut with pulling plate 3；
Hydraulic screw extractor 5, with tubular shell, the periphery of tubular shell is equipped with external screw thread, and hydraulic screw extractor 5 is arranged in
It is spirally connected in 3 installation screw of pulling plate by external screw thread and pulling plate 3.
In use, by being sleeved on transmission shaft tapered roller bearing internal ring by taper hole after 1 pairing of snap ring being divided into two
Whole circle conical roller 1-4 on, notice that 1 annular inner stopper 1-1 of snap ring should be sticked in whole circle conical roller 1-4 big ends end face, then
Body 2 is sleeved on snap ring 1, to prevent snap ring 1 from falling apart, then snap ring 1 is connected with pulling plate 3 with two studs 4, up and down
The operation handle of hydraulic screw extractor 5 on pulling plate 3 is pulled, the piston rod external part of 5 hydraulic cylinder of hydraulic screw extractor is made to extend downwardly and be driven
Axis shaft end forces transmission shaft to move down after offseting, until transmission shaft is detached with tapered roller bearing internal ring, in the process, card
1 annular inner stopper 1-1 of ring plays the role of blocking inner ring and inner ring assembly moves down.
Another scheme is not use hydraulic screw extractor 5, the hexagon-headed bolt that is spirally connected in 3 installation screw of pulling plate (figure
In do not show), the hexagon-head of hexagon-headed bolt upper end is pulled with spanner, hexagon-headed bolt lower end is made to extend downwardly and transmission shaft
Shaft end forces transmission shaft to move down after offseting, until transmission shaft is detached with tapered roller bearing internal ring.
The above embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with this skill
The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this
It encloses, all equivalent change or modifications substantially made according to the spirit of the present invention should all cover the protection model in the utility model
In enclosing.
