Description

Bearing puller

Technical Field

The utility model belongs to the technical field of the frock part, concretely relates to bearing draws horse.

Background

When the bearing is disassembled in a narrow space, the conventional puller is not easy to install due to the small operation space, and the puller is easy to scratch the surface of the shaft, so that a special puller needs to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose: provided is a bearing puller which can detach a bearing in a narrow space and does not damage the surface of a shaft.

The utility model discloses technical scheme: a bearing puller comprises a screw, a handle fixed on the screw, an arch frame and a nut, wherein the arch frame is assembled on the screw through threads, and the nut is assembled on the arch frame through threads; the internal thread of the arched frame is in threaded fit with the screw, and the external thread of the arched frame is in threaded fit with the nut.

The bow-shaped frame is integrally machined firstly, the matching size of the bow-shaped frame and the working bearing is guaranteed, and then the bow-shaped frame and the working bearing are divided into two halves, so that the bearing is conveniently clamped.

The utility model has the advantages that: the bow-shaped frame is firstly installed on the disassembled bearing, then the nut is screwed outside the bow-shaped frame, then the screw is screwed into the bow-shaped frame, and the handle is rotated, so that the bearing can be disassembled.

Drawings

Fig. 1 is a schematic structural view of the bearing puller of the present invention;

the reference numbers in the drawings are respectively: 1. screw 2, handle 3, nut 4, bow.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Examples

A bearing puller comprises a screw 1, a handle 2 fixed on the screw 1, an arch bracket 4 assembled on the screw 1 through threads, and a nut 3 assembled on the arch bracket through threads.

After the nut 3 is unscrewed in the above embodiment, the bracket 4 can be divided into two halves, which are respectively installed on two sides of the disassembled bearing, and then the nut 3 is screwed on the bracket 4. The bearing can be removed by screwing the screw 1 into the bracket 4 until the shaft is reached and continuing to turn the handle.

Claims (2)
