RECIPROCATING SAW - A simplified explanation of the abstract

This abstract first appeared for US patent application 18650629 titled 'RECIPROCATING SAW

Simplified Explanation:

The patent application describes a reciprocating saw with a unique drive mechanism that converts rotary motion into linear reciprocating motion.

  • The drive mechanism includes a driven gear, connecting rod, and spindle.
  • The connecting rod is coupled to the spindle by a roller pin, allowing for the translation of motion.
  • The support assembly includes bearings that rotationally support the roller pin within a housing.

Key Features and Innovation:

  • Unique drive mechanism for converting rotary motion into linear reciprocating motion.
  • Roller pin coupling for translating motion effectively.
  • Support assembly with bearings for rotational support.

Potential Applications:

This technology can be used in various power tools and machinery that require reciprocating motion, such as saws, drills, and sanders.

Problems Solved:

This technology addresses the need for efficient translation of motion from rotary to linear in reciprocating saws, improving overall performance and reliability.

Benefits:

  • Improved efficiency in converting motion.
  • Enhanced performance and reliability in reciprocating saws.
  • Potential for increased precision in cutting and other applications.

Commercial Applications:

The technology can be applied in the manufacturing of power tools for construction, woodworking, metalworking, and other industries. It can also be used in DIY tools for home improvement projects.

Questions about Reciprocating Saw Technology:

1. How does the unique drive mechanism in this reciprocating saw improve its performance compared to traditional models? 2. What are the potential cost implications of implementing this technology in commercial power tools?


Original Abstract Submitted

A reciprocating saw includes a housing, a motor, a drive mechanism, and a support assembly. The drive mechanism includes a driven gear, a connecting rod, and a spindle. A first end of the connecting rod is moveably coupled to the spindle by a roller pin. Rotary motion of the motor is translated into linear reciprocating motion of the spindle by the driven gear and the connecting rod. The support assembly rotationally supports the roller pin and includes a housing which defines a slot. A first bearing is positioned within the slot at a first end of the roller pin, and a second bearing is positioned within the slot at a second end of the roller pin. At least one of the first end and the second end of the roller pin extends completely though the first bearing and the second bearing, respectively.
