Description:DESCRIPTION:
Field of the invention:
[0001] The present disclosure generally relates to the technical field of mechanical tools, and in specific, relates to a multi-functional bearing puller that is adapted to remove both internal and external bearings immovably fixed to an external body, thereby allowing for smooth between different operational modes, enhancing versatility and efficiency.
Background of the invention:
[0002] A bearing is a mechanical component that facilitates smooth and controlled motion between two parts, typically by reducing friction. It allows one part to rotate and move linearly relative to another while minimizing wear and tear. Bearings are essential in various applications requiring rotational or linear motion, such as machinery, vehicles, and appliances. They support shafts and axles, enabling them to rotate smoothly while carrying heavy loads, thereby improving efficiency and extending the lifespan of the equipment. Bearings are used in everything from simple tools like hand drills to complex systems such as aircraft engines and industrial machinery.

[0003] While bearings are crucial for reducing friction and enabling smooth motion, they have some drawbacks. One major limitation is their susceptibility to wear and tear, especially under heavy loads, high speeds, and harsh environmental conditions. Over time, bearings can degrade, leading to increased friction, noise, and eventual failure if not properly maintained. Bearings also require regular lubrication to function effectively, and inadequate lubrication that causes overheating and accelerated wear. Additionally, bearings are sensitive to misalignment, contamination, and improper installation, all of which can reduce their performance and lifespan. In some applications, the complexity of bearing assemblies can increase maintenance costs and downtime.

[0004] Bearing pullers are specialized tools used to remove bearings from shafts and housings without causing damage to the bearing and surrounding components. They work by gripping the inner or outer race of the bearing and applying force to pull it off from the shaft or out of its housing. Bearing pullers are essential in maintenance and repair tasks where bearings must be replaced and inspected.

[0005] The bearing pullers are primarily categorized into two types: inner bearing pullers and external bearing pullers. Inner bearing pullers are specifically designed to extract bearings lodged within a housing, while external bearing pullers are intended for removing bearings that are stuck on a shaft. Each type is specialized for its respective task, meaning that carrying multiple tools for different types of bearing removal might be cumbersome and impractical. The necessity to switch between different pullers based on the application can complicate maintenance tasks and add to the logistical challenges of handling various bearing issues.

[0006] In existing technology, a multi-purpose bearing extractor is known. The multi-purpose bearing extractor comprises a barre, a burner block, a mandril, a fixing piece, left and right connecting rods, and two Kelly rods. The barre has a vertical and horizontal part, and the burner block fits inside the horizontal part. The fixing piece is connected to the left and right connecting rods, which in turn are connected to the Kelly rods. The Kelly rods are articulated by a pin shaft and mandril, and the ends of the Kelly rods have clamping pieces for holding the bearing. The multi-purpose bearing extractor that allows a user to dismantle different sizes and types of bearings. However, the multi-purpose bearing extractor might not remove an external bearing that is affixed to an external surface of the housing.

[0007] Therefore, there is a need for a multi-functional bearing puller that is adapted to remove both internal and external bearings immovably fixed to an external body. There is also a need for multi-functional bearing puller that is easy to operate, making complex tasks more straight forward without required skilled person. There is also a need for a multi-functional bearing puller that is cost-effective, user-friendly, and reduce the need for purchasing and maintaining multiple tools. Furthermore, there is also a need for a multi-functional bearing puller that is manufactured with at least one durable material of high quality to ensure long-term usage and is portable to use.
Objectives of the invention:
