RANDOM ORBIT SANDER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18524189 titled 'RANDOM ORBIT SANDER

Simplified Explanation

The abstract describes a random orbit sander with a motor shaft and an eccentric carrier that allows for eccentrically orbiting sanding pad movement.

• The random orbit sander includes a housing enclosing a motor with a motor shaft that can rotate about a first axis.
• An eccentric carrier, coupled to the motor shaft, has a circular internal bore defining a second axis offset from the motor shaft.
• A bearing is placed within the circular internal bore of the eccentric carrier to support a sanding pad that rotates about the first axis in an eccentrically orbiting manner.
• The motor shaft and the eccentric carrier are integrated as a single piece.

Potential Applications

This technology can be used in various woodworking and finishing applications where a random orbit sander is required for smoothing surfaces.

Problems Solved

This innovation solves the problem of achieving smooth and uniform sanding results on various surfaces by providing an eccentrically orbiting sanding pad.

Benefits

The benefits of this technology include improved sanding efficiency, reduced vibration, and enhanced surface finish quality.

Potential Commercial Applications

Potential commercial applications of this technology include woodworking shops, furniture manufacturing, automotive refinishing, and DIY home improvement projects.

Possible Prior Art

One possible prior art for this technology could be traditional random orbit sanders with separate motor shafts and eccentric carriers, which may not provide the same level of integration and efficiency as the described invention.

Unanswered Questions

How does the integration of the motor shaft and eccentric carrier improve the performance of the random orbit sander?

The integration of the motor shaft and eccentric carrier in the random orbit sander improves performance by reducing vibration and increasing efficiency in sanding operations.

What materials are used in the construction of the eccentric carrier and bearing to ensure durability and longevity of the sander?

The eccentric carrier and bearing are typically made of durable materials such as metal alloys or high-quality plastics to ensure longevity and reliable performance of the random orbit sander.

Original Abstract Submitted

A random orbit sander includes a housing and a motor enclosed within the housing. The motor includes a motor shaft that is rotatable about a first axis. An eccentric carrier coupled to the motor shaft includes a circular internal bore that defines a second axis that is offset from the motor shaft. A bearing is received within the circular internal bore of the eccentric carrier. A sanding pad is supported by the bearing and is rotatable about the first axis in an eccentrically orbiting manner. The motor shaft and the eccentric carrier are integrally formed as a single piece.
