POWER TOOL WITH PARTITION ASSEMBLY BETWEEN TRANSMISSION AND MOTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033893 titled 'POWER TOOL WITH PARTITION ASSEMBLY BETWEEN TRANSMISSION AND MOTOR

Simplified Explanation

The abstract describes a power tool that includes a tool housing and a motor assembly. The motor assembly has a rear end portion, a front end portion, and a motor output shaft. A transmission housing is coupled to the motor housing with a transmission received in the transmission housing, to which the motor output shaft is drivingly coupled. A partition assembly includes a rear cover covering a rear end portion of the transmission housing that faces the front end portion of the motor and a seal. The rear cover of the transmission housing, the front end portion of the motor, and the seal together define at least a first labyrinth path and a second labyrinth path therebetween configured to inhibit grease or dust migration between the transmission housing and the motor assembly.

• The power tool has a motor assembly with a rear end portion, a front end portion, and a motor output shaft.
• A transmission housing is coupled to the motor housing with a transmission received in it.
• The motor output shaft is drivingly coupled to the transmission.
• A partition assembly includes a rear cover and a seal.
• The rear cover, front end portion of the motor, and the seal define labyrinth paths to prevent grease or dust migration.

Potential applications of this technology:

• Power tools such as drills, saws, or grinders that require a motor and transmission assembly.
• Industrial machinery that uses power tools with similar motor and transmission configurations.

Problems solved by this technology:

• Prevents grease or dust migration between the transmission housing and the motor assembly.
• Ensures the longevity and efficiency of the power tool by maintaining proper lubrication and preventing contamination.

Benefits of this technology:

• Increases the lifespan of the power tool by preventing damage caused by grease or dust migration.
• Reduces the need for frequent maintenance and repairs.
• Improves the overall performance and reliability of the power tool.
