Abstract
The utility model relates to a self-lubricating worm and gear speed reducer which comprises a driving gear pair, a worm and a worm gear which are all arranged in a box body, wherein the upper end and the lower end of the worm are vertically supported in the box body through a bearing; the driving gear pair is connected with the upper end of the worm in a driving mode; the lower end of the worm is sealed in the box body through a lock plug; the worm is meshed with the worm gear; the worm is provided with an axial through hole; the lock plug is internally provided with an oil pump or the lock plug is an oil pump lock plug; and the oil pump or the oil pump lock plug is communicated with the axial through hole. The oil pump is designed into the lock plug of the worm, the lubricating oil is delivered to the top end of the worm through the axial through hole of the worm so as to lubricate the inner part of the speed reducer from top to bottom, the whole structure is compact, the lubricating effect is good, the whole appearance is not influenced, the mounting space is reduced, and the self-lubricating worm and gear speed reducer is convenient to transport and assemble.
Description
Technical field
The utility model relates to a kind of worm-gear speed reducer with self-lubricating function.
Background technique
The lubrication system of tradition speed reducer adopts the tyre oil pump lubricated to fuel feeding in the casing, and oil pump is connected outside the casing, influences the casing monnolithic case, and takies installing space, transportation, assembling inconvenience.
Summary of the invention
In order to solve traditional speed reducer lubricated casing monnolithic case that influences of oil pump feed in addition; And take installing space, deficiencies such as transportation, assembling inconvenience, it is a kind of simple in structure, compact that the utility model provides; Do not influence the speed reducer profile; Do not take installing space, be convenient to transportation and assembling, the selflubricating worm-gear speed reducer of high lubricating effect.
The technological scheme that the utility model adopts is: a kind of selflubricating worm-gear speed reducer; Comprise the driving gear wheel set, the worm and worm wheel that all are arranged in the casing; The upper/lower terminal of worm screw is supported in the casing through bearing is vertical, and the driving gear wheel set drives and connects the worm screw upper end, and the lower end of worm screw is in stifle is sealed in casing; The worm meshing worm gear; It is characterized in that said worm screw is provided with axial hole, being provided with oil pump or stifle in the said stifle is the oil pump stifle, and oil pump or oil pump stifle are communicated with axial hole.
Further, the center of said axial hole is the axle center of worm screw.
The oil pump of this speed reducer is installed in the stifle of worm screw lower end or with stifle and is integrated; The shaft of oil pump installs to the worm screw axial hole; Drive oil pump work by worm screw and from the worm screw axial hole, lubricant oil is delivered to the ejection of worm screw upper end; Thereby driving gear wheel set, worm gear, worm screw are lubricated the speed reducer high lubricating effect; Lubricant oil is collected to the casing inner bottom part and forms oil sump, and oil pump or the entering stifle oil pump of lubricant oil in bearing gets into stifle realized the lubrication oil circulation use, and lubricant oil is difficult for revealing, and speed reducer is safe in utilization.
The utility model in the worm screw stifle, is delivered to the oil pump design worm screw top through the axial hole of worm screw with lubricant oil and speed reducer inside is lubricated compact overall structure from top to bottom; High lubricating effect; And do not influence monnolithic case, reduce installing space, be convenient to transportation, assembling.
