Description
Technical field
This utility model relates to granulator transmission device, and more particularly, to a kind of non-maintaining pressure roller assembly gland and pressure roller are total
Become.
Background technology
In pressure roller assembly, pressure roller is to be fixed in pressure roller shaft by roller bearing, in order to allow equipment operating more suitable
Freely, in the junction of each part lubricating oil generally to be added, play lubrication.Existing pressure roller assembly adopts sealing device sealing effect
Really poor be easily damaged, because substantial amounts of dust can be produced around when pressure roller assembly runs, because lubricating oil is liquid, long fortune for a long time
Turn and will flow out equipment so that the abrasion of equipment increases, and dust also easily enters in pressure roller assembly, causes pressure roller assembly to burn,
Impact produces.
Content of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of structure simple, sealing effectiveness
Good, it is easily installed, long service life, a kind of non-maintaining pressure roller assembly gland and the pressure roller assembly of production requirement can be met.
This utility model is achieved through the following technical solutions:
A kind of non-maintaining pressure roller assembly, including pressure roller shaft, pressure roller shaft is connected with pressure roller by bearing, and the both sides of bearing are provided with
Sealing gland, described pressure roller inner arc surface is in step-like, and the shape of described sealing gland is suitable with the shape phase of pressure roller inner arc surface
Should, and be to threaded between the exterior arc surface of sealing gland and pressure roller inner arc surface；Set on the inner face of described sealing gland
There are annular protrusion and annular groove, in annular groove, be provided with sealing ring, annular protrusion is placed in the axis hole of pressure roller, described sealing ring
It is pressed on the step surface of pressure roller inner arc surface；It is located in described pressure roller shaft and be provided with ring set between bearing.
Described pressure roller shaft is provided with two annular slots, is provided with O-ring seal, described O-ring seal in two annular slots
Contact with the pars intermedia of two ends sealing gland inner arc surface respectively.
Annular groove quantity on described sealing gland inner face is at least one.
Described annular groove is located at the outside of annular protrusion.
Described ring set is provided with screwed hole, is provided with holds out against screw at screwed hole.
The end face of institute's sealing gland is provided with through hole, is provided with female thread in table top in the pressure roller corresponding with lead to the hole site
Hole, is provided with lock screw between through hole and internal thread hole.
The utility model has the advantages that: can preferably pressure roller assembly be carried out close using the technical solution of the utility model
Envelope, prevents oil leak and dust from entering inside pressure roller assembly, makes the lubricant effect of pressure roller assembly more preferably, extend pressure roller total
Become service life, decrease disorderly closedown, improve production efficiency.
