Description
Technical field
The utility model relates to a kind of speed reducer end cap, is a kind of double-deck ne-leakage end cap specifically.
Background technique
The lubrication of speed reducer internal gear, bearing is directly connected to its working life, and the lubricant oil after bearing lubrication is usually by output shaft transparent cover seepage, even if set up multiple-sealed or oil sealing, long-term transmission easily causes bad seals seepage lubricant oil after exporting.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of structure simple, can effectively prevent lubricant oil with the double-deck ne-leakage end cap of output shaft by end cap seepage.
The technical solution adopted in the utility model: a kind of double-deck ne-leakage end cap, it comprises flange end cap and shrouding, the lower end of flange end cap is coaxially provided with the sealing drum of a sealing cross-under speed reducer output shaft or input shaft and the seal snap ring of a sealing location clamping box body of speed reducer, sealing drum inwall is provided with the multiple-sealed groove be sealed and matched with speed reducer output shaft or input shaft, a circle oil trap is provided with in the middle part of flange end cap inwall, be provided with drainback passage in flange end cap, oil trap is communicated to the cavity between sealing drum and seal snap ring through drainback passage; The upper end of flange end cap is provided with sealed step, and sealed step arranges oil sealing, shrouding sealing-in in the upper end of flange end cap and compress oil sealing in sealed step.
Further, described shrouding is provided with transparent cover hole.
Again further, described multiple-sealed groove is that mazy type is arranged.
Adopt technique scheme, the beneficial effects of the utility model are: when being used on speed reducer, the sealing drum of flange end cap lower end is connected on output shaft or input shaft, the multiple-sealed groove sealing of mazy type of sealing drum inwall, seal snap ring corresponding box body of speed reducer bearing saddle bore location and installation, after bearing lubrication, lubricant oil is sealed by the multiple-sealed groove of mazy type and realizes sealing, a small amount of oil seepage is in oil trap, bearing is back to through drainback passage by oil trap, in the cavity that seal snap ring and sealing drum outer wall are formed, reduce the lubricants capacity along output shaft or the outside seepage of input shaft, the oil sealing that flange end covers end sealed step compresses through shrouding, will can improve output shaft or the sealability of input shaft between end cap entirety further, stops, by output shaft or input shaft through end cap seepage, to improve sealability.Atresia or have transparent cover hole to be applicable to stifle or transparent cover to use on shrouding.
Accompanying drawing explanation
