Description

A quick detachable ball bearing device

technical field

The utility model belongs to the technical field of automation equipment, in particular to a quickly detachable ball bearing device.

Background technique

Today's industrial machinery and equipment are inseparable from the use of bearings. When the bearings on the equipment are damaged, not only noise will be generated, but also other parts of the entire equipment will be damaged, until the entire equipment is scrapped. Since the bearing is installed into the bearing seat from one direction, usually the bearing seat must be disassembled before the bearing can be pushed out from the other direction. Therefore, it is time-consuming and laborious to replace the bearing, which will affect the production and cause indirect economic losses.

Therefore, a new technical solution is needed to solve the above technical problems.

Utility model content

Technical problem: The utility model provides a device that can quickly disassemble the ball bearing, which greatly reduces the time for replacing the bearing.

Technical solution: The utility model discloses a quickly detachable ball bearing device, which includes a detachment device body and a pull claw. The end arm, the pull claw includes a pull claw body and a pull claw head located at the lower end of the pull claw body for inserting into the bearing groove. The pull claw head is spherical, and the pull claw is in a non-working state. The surface close to the inner ring of the bearing and the outer ring of the bearing is planar, and the claw is fixedly connected with the support cylinder of the dismantling device body through the end arm in the working state.

As a further optimization of the utility model, the pull claw body described in the utility model is provided with several fixing holes for the end arms to be fixedly connected thereto, and the end arms are fixed in pairs on both sides of the pull claw.

As a further optimization of the utility model, at least two pull claws are provided on the body of the disassembly device described in the utility model.

As a further optimization of the utility model, the pull claw body described in the utility model has a radian structure, and the radian direction of the pull claw body is consistent with the direction of the spherical curved surface of the pull claw head.

Beneficial effects: Compared with the prior art, the utility model has a simple structure and low cost, and by using the improved dismounting bearing device, the damaged bearing can be quickly pulled out and replaced with a new one, greatly reducing the maintenance of mechanical equipment investment in human and material resources.
