IMPACT TOOL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033883 titled 'IMPACT TOOL

Simplified Explanation

The abstract describes an impact tool that includes a housing, a motor, and a drive assembly. The drive assembly converts the rotational input from the motor into consecutive rotational impacts on a workpiece. The drive assembly includes a camshaft with a front and rear portion that define a carrier. A thrust bearing engages with the rear portion of the camshaft, and a gear assembly is coupled between the motor shaft and the drive assembly. The gear assembly includes a ring gear and multiple planet gears that mesh with the ring gear. Each planet gear is coupled to the carrier of the camshaft, and the ring gear supports the rear portion of the camshaft via the planet gears.

  • The impact tool has a motor that generates rotational power.
  • The drive assembly converts the motor's rotational input into consecutive rotational impacts on a workpiece.
  • The drive assembly includes a camshaft with a front and rear portion that define a carrier.
  • A thrust bearing engages with the rear portion of the camshaft to provide support.
  • A gear assembly is coupled between the motor shaft and the drive assembly.
  • The gear assembly includes a ring gear and multiple planet gears that mesh with the ring gear.
  • Each planet gear is coupled to the carrier of the camshaft.
  • The ring gear rotationally and radially supports the rear portion of the camshaft via the planet gears.

Potential applications of this technology:

  • Construction and building industry
  • Automotive industry
  • Manufacturing and assembly lines
  • Maintenance and repair work

Problems solved by this technology:

  • Provides a mechanism to convert rotational power into consecutive rotational impacts.
  • Ensures proper support and alignment of the camshaft.
  • Efficiently transfers power from the motor to the drive assembly.

Benefits of this technology:

  • Increased efficiency and productivity in impact applications.
  • Improved durability and reliability of the impact tool.
  • Enhanced control and precision in impact operations.
  • Reduced wear and tear on the components of the impact tool.


Original Abstract Submitted

an impact tool includes a housing, a motor supported within the housing and having a motor shaft, a drive assembly configured to convert a continuous rotational input from the motor shaft to consecutive rotational impacts upon a workpiece, the drive assembly including a camshaft having a front portion and a rear portion defining a carrier, the rear portion being closer to the motor than the front portion, a thrust bearing engageable with the rear portion of the camshaft, and a gear assembly coupled between the motor shaft and the drive assembly. the gear assembly includes a ring gear and a plurality of planet gears meshed with the ring gear. each of the plurality of planet gears is coupled to the carrier of the camshaft, and the ring gear rotationally and radially supports the rear portion of the camshaft via the plurality of planet gears.
