Being left between the mounting end for the reductor shaft being rotatably assorted with box body of speed reducer, the transparent cover and the reductor shaft is used for
The first gap of lubricating grease is accommodated, and the inner end in first gap is furnished with oil sealing；The transparent cover is provided with lubricating grease runner,
The front end of the lubricating grease runner and lubricating cup pipeline connection；The gland and the transparent cover outer face are affixed, and the gland
Medial surface edge and transparent cover outer face palette；The inner face of the gland is circumferentially with to be connected with gap outer end
Groove, and the groove connects with the end of the lubricating grease runner.
The second gap is left between the gland and the reductor shaft, wherein the width in second gap is less than first
The width in gap.
The lubricating grease runner is divided into first paragraph and second segment, and wherein first paragraph is vertically arranged with second segment, and first
The front end of section is connected with lubricating cup bottom thread, and keeps first paragraph inner chamber to be connected with lubricating cup inner chamber, the end of first paragraph and second
Duan Qianduan is connected, and the end of second segment is connected with the groove of gland inner face.
The transparent cover is affixed by seam and the box body of speed reducer, and the gland is affixed by seam and the transparent cover.
The gland is maze-type structure, and the endoporus of the gland has " U " type annular groove, the annular slot number of described " U " type
Amount is general 2-3, when width is enough, can reach more than 5 " U " type annular groove, described " U " type annular groove is played
The effect of oil return, prevents oil leak.
The technical thought of the utility model structure is：Oil sealing in sealing device is also functioned to while sealing lubricating oil
Effect that the lubricating oil of heat and lubricating grease are separated, it is to avoid the loss by dissolution of lubricating grease.Labyrinth type pressure in sealing device
Cap-shaped is into a kind of contactless radial direction mechanical seal, it will ensure that the lubricating grease between oil sealing is seldom lost in, this just makes outer
Boundary's pollutant is not readily accessible to oil seal lip, so as to reduce the abrasion of oil seal lip, improves the service life of oil sealing, it is ensured that
Not the revealing of lubricating oil can not enter lubricating oil with environmental contaminants.The outer end of labyrinth gland although lubricating grease can be lost in,
But also the pollutant of outside invading is taken away simultaneously so that the new lubricating grease supplemented by lubricating cup keeps cleaning.
In use, lubricating grease is added in lubricating cup, then lubricating grease flows into the recessed of gland inner face by lubricating grease runner
In groove, and flowed into by groove in the first gap between transparent cover and reductor shaft, now, with the rotation of reductor shaft, profit
Consistent lubricant is covered with the mounting end surface of whole reductor shaft, and gland groove, the first gap and the second inner space are full of
Lubricating grease, and the oil sealing of the first gap end plays sealing function, prevents lubricating grease from flowing into casing.
The beneficial effects of the utility model are：1) the sealing problem under particular surroundings operating mode is solved；
2) Seepage at decelerator oil sealing has been prevented；
3) ensure that lubricating oil by outside contamination, that is, does not extend the replacement cycle of lubricating oil, making for decelerator is improved again
Use the life-span；
4) it is simple in construction, manufacture easy to process, cost is low, it is easy to install and safeguard.
