Speed reducer for worm wheel to throw oil so as to lubricate bearing

Abstract

The invention relates to a speed reducer for a worm wheel to throw oil so as to lubricate a bearing. The speed reducer comprises a shell, the worm wheel and a worm. The worm is supported in the shell through a bearing block. An oil groove is formed in the inner wall of the part, below the worm wheel rotation tangent line position corresponding to the position above the bearing block, of the shell. The oil groove communicates with the bearing supporting the worm in the bearing block through oil ways on the shell and the bearing block, wherein the oil ways communicate with one another. The oil groove is formed in the inner wall of the part, below the worm wheel rotation tangent line position corresponding to the position above the bearing block, of the shell to collect oil, oil passes through the oil ways to lubricate the bearing, the shell communicates with the bearing block through the oil ways, the worm wheel throws lubricating oil in the shell out in the tangent line direction during rotation, the lubricating oil enters the oil groove or the oil ways below the worm wheel, and no power device needs to be additionally arranged; and lubrication can be continuously kept when the worm wheel works, it is ensured that the worm supports the continuous lubrication of the bearing, and the service life is better prolonged.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a speed reducer for a worm gear throwing oil to lubricate a bearing. Background technique [0002] The existing worm gear reducer usually uses the lubricating oil in the box to lubricate itself under the rotation of the worm and the worm wheel, but the bearing seat supported by the worm cannot be effectively lubricated, which affects the service life of the whole machine. Contents of the invention [0003] The invention provides a reducer with simple structure and capable of effectively lubricating the worm wheel support bearing with oil throwing lubricating bearing. [0004] The technical solution adopted in the present invention: a reducer for worm wheel oil-lubricated bearings, including a housing, a worm wheel and a worm, the worm is supported in the housing through a bearing seat, and its feature is that: corresponding to the position below the tangential line of the worm wheel rotation ...
