A table saw, including a worm drive, comprising a driveshaft configured to rotate about an axis of rotation and a worm configured for rotation with said driveshaft, characterized in that the table saw further comprises: a seal member including an inner seal defining a shaft opening through which said driveshaft extends, said inner seal extending radially away from said axis of rotation no more than a first distance; and a shield mounted on said driveshaft between said worm and said seal member, said shield extending radially away from said axis of rotation for at least a second distance that is equal to or greater than said first distance, wherein said seal member further includes an outer seal and a diaphragm extending from said inner seal to said outer seal, said diaphragm extends radially away from said axis of rotation no more than a third distance, and said third distance is greater than said second distance, the table saw further comprising: a worm gear meshed with said worm, wherein said worm and said worm gear are at least partially submerged in a liquid lubricant, wherein said driveshaft is configured such that rotation of said driveshaft causes the meshing of said worm and said worm gear to generate a stream of lubricant directed toward said seal member, and said shield is located between said stream of lubricant and said seal member and is configured (i) to block said stream of lubricant from directly striking said inner seal, and (ii) to block partially said stream of lubricant from directly striking said diaphragm. a driveshaft configured to rotate about an axis of rotation and a worm configured for rotation with said driveshaft, characterized in that the table saw further comprises: a seal member including an inner seal defining a shaft opening through which said driveshaft extends, said inner seal extending radially away from said axis of rotation no more than a first distance; and a shield mounted on said driveshaft between said worm and said seal member, said shield extending radially away from said axis of rotation for at least a second distance that is equal to or greater than said first distance, a seal member including an inner seal defining a shaft opening through which said driveshaft extends, said inner seal extending radially away from said axis of rotation no more than a first distance; and a shield mounted on said driveshaft between said worm and said seal member, said shield extending radially away from said axis of rotation for at least a second distance that is equal to or greater than said first distance, wherein said seal member further includes an outer seal and a diaphragm extending from said inner seal to said outer seal, said diaphragm extends radially away from said axis of rotation no more than a third distance, and said third distance is greater than said second distance, the table saw further comprising: a worm gear meshed with said worm, wherein said worm and said worm gear are at least partially submerged in a liquid lubricant, wherein said driveshaft is configured such that rotation of said driveshaft causes the meshing of said worm and said worm gear to generate a stream of lubricant directed toward said seal member, and said seal member further includes an outer seal and a diaphragm extending from said inner seal to said outer seal, said diaphragm extends radially away from said axis of rotation no more than a third distance, and said third distance is greater than said second distance, the table saw further comprising: a worm gear meshed with said worm, wherein said worm and said worm gear are at least partially submerged in a liquid lubricant, wherein said driveshaft is configured such that rotation of said driveshaft causes the meshing of said worm and said worm gear to generate a stream of lubricant directed toward said seal member, and a worm gear meshed with said worm, wherein said worm and said worm gear are at least partially submerged in a liquid lubricant, wherein said driveshaft is configured such that rotation of said driveshaft causes the meshing of said worm and said worm gear to generate a stream of lubricant directed toward said seal member, and said shield is located between said stream of lubricant and said seal member and is configured (i) to block said stream of lubricant from directly striking said inner seal, and (ii) to block partially said stream of lubricant from directly striking said diaphragm.
