Abstract

The utility model relates to an inner bearing puller which belongs to the mechanical field. The whole inner bearing puller is a connector which is provided with a thick hollow cylinder and a thin hollow cylinder. The outer port of a thick pipe is open. Four holes with internal threads are bore at equal space along the circumference of the pipe body, and positioning screws are screwed in the holes. The outer port of a thin pipe is closed. A hole with internal threads is bored in the centre of the end surface of the thin pipe, and a push rod with external threads is screwed into the hole. The outer end part of the push rod is provided with a shank hole, and the inner end part of the push rod is in a taper shape. When the utility model is used, the inner bearing puller is covered on an inner bearing, and the positioning screws are clamped in a groove of the inner bearing. The push rod is rotated, and the inner bearing can disengage from the top of a shaft. When the technical scheme is adopted, a bearing inner ring can be taken out without damage.

Description

The inner bearing chest expander

1, technical field: inner bearing chest expander of the present utility model belongs to mechanical field.

2, background technology: in automobile, motorcycle maintenance process, the Internal and external cycle that often runs into bearing breaks away from, and the situation that inner ring can't take out generally all is to use destructive ways such as gas cutting or strike inner ring is taken out, and is easy to cause the damage at other positions like this.

3, summary of the invention: the purpose of this utility model is to propose a kind of damaged inner bearing chest expander that takes out bearing inner race that do not have.

The purpose of this utility model is achieved in that inner bearing chest expander integral body is the cylindrical connectors of one thick one thin two cavitys, and the extra heavy pipe external port is uncovered, and body equidistantly has four holes along circumference, all has internal thread, is rotary with set screw.The sealing of tubule external port, the end face center drilling has internal thread, screws in and is with externally threaded push rod, and the push rod outer end has delthyrium, and inner end is taper.The inner bearing chest expander is enclosed within on the inner bearing, and set screw is stuck in the inner bearing groove, and the rotation push rod just can be gone up disengaging from axle with inner bearing.

Owing to carry out technique scheme, just can realize not having the damaged bearing inner race that takes out.

4, description of drawings: concrete structure of the present utility model is provided by following drawing and description

Fig. 1 is an inner bearing chest expander profile

Fig. 2 is an inner bearing chest expander vertical view

5, the specific embodiment:

Legend: 1, set screw 2, extra heavy pipe 3, tubule 4, push rod 5, delthyrium

Embodiment: shown in Fig. 1-2, inner bearing chest expander integral body is the cylindrical connectors of one thick one thin two cavitys, and the extra heavy pipe external port is uncovered, and body equidistantly has four holes along circumference, all has internal thread, is rotary with set screw.The sealing of tubule external port, the end face center drilling has internal thread, screws in and is with externally threaded push rod, and the push rod outer end has delthyrium, and inner end is taper.

During use, the inner bearing chest expander is enclosed within on the inner bearing, set screw is stuck in the inner bearing groove, and the rotation push rod just can be gone up disengaging from axle with inner bearing.
