Description
Technical field
The utility model relates to running shaft technical field, especially relates to a kind of rotation sealing structure of shaft end.
Background technique
At present, along with Chinese society expanding economy, stirrer kind also gets more and more, function also presents variation, but the requirement of people can not be met, the output such as produced is uneven, there is void ratio larger, especially there is very large problem in the sealing of powder mixer, the stirrer that sealability is bad, the dusty gas in cylindrical shell easily leaks and dust easily enters bearing, causes bearing oil to leak, so the quality in order to improve the product after stirring, must transform stirrer.
Model utility content
The technical problems to be solved in the utility model is: in order to the sealing overcoming powder mixer of the prior art exists very large problem, the stirrer that sealability is bad, dusty gas in cylindrical shell easily leaks and dust easily enters bearing, cause the problem that bearing oil leaks, provide a kind of and rotate sealing structure of shaft end.
The utility model solves the technological scheme that its technical problem adopts: a kind ofly rotate sealing structure of shaft end, comprise the returning charge shaft shoulder, sealing seat, end casing, bearing support, electric motor stand, bearing cap, bearing spacer and locking nut, the described returning charge shaft shoulder is on the rotary shaft sheathed, described sealed socket sleeve is located on the returning charge shaft shoulder, described end casing is on the rotary shaft sheathed and be fixedly connected with sealing seat, described bearing sleeve is established on the rotary shaft and is fixedly connected with end casing, described bearing spacer is on the rotary shaft sheathed, described bearing cap to be set on bearing spacer and to be fixedly connected with bearing support, described locking nut is on the rotary shaft sheathed and contact with bearing spacer, described end casing is fixedly connected with electric motor stand.
In order to make to have good sealing between the returning charge shaft shoulder and sealing seat, between the described returning charge shaft shoulder and sealing seat, be also provided with sealing gasket.
Adopt the effect of the reverse thread of the returning charge shaft shoulder, and outside framework oil seal, gas seal and lubricant grease combine and seal mechanical cylindrical shell, prevent the dusty gas in cylindrical shell from leaking and dust enters bearing, prevent bearing oil to leak.
The beneficial effects of the utility model are: rotation sealing structure of shaft end of the present utility model, adopt the effect of the reverse thread of the returning charge shaft shoulder, and outside framework oil seal, gas seal and lubricant grease combination seal mechanical cylindrical shell, prevent the dusty gas in cylindrical shell leak and dust enter bearing, prevent bearing oil to leak.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
