Abstract
The utility model relates to an improved axle end axle bed system and belongs to the drive component of an axle series, comprising a bearing seat, a bearing, a bearing sleeve, a front and a back end cover and an axle head coupled with a main axle, wherein, the tail part of the bearing sleeve is provided with an oil filling pipe communicated with the interior of the bearing sleeve and an oil level scale; an elastic sealing ring is arranged between the bearing sleeve and the front and the back end cap; a floating type mechanical sealing friction pair is arranged between the bearing sleeve and the axle head. The utility model adopts machine oil to lubricate the bearing; through a dynamic and a static seal components, the sealing is reliable, the breaking-in is automatic, and the service life is long. In addition, a conical roller bearing is used for matching with an arcuate nylon lining seat, the aligning can be realized, the tail end axle seat has the aligning quantity of theta <=30 DEG and the axial direction telescopic quantity of delta <=60 mm, the carrying capacity is also increased.
Description
Technical field
It is transmission part that the utility model relates to a kind of axle, the tail end axle bed system of outstanding spindle.
Technical background
Machinery is in operation process, its main body is the running and the transmission of axle system, wherein whether bearing block structure is rationally and science, can directly influence machinery driving efficiency, particularly machinery is even more important under environment ten minutes condition of severe, conventional shaft tail end axle bed system adopts the plain bearing bearing of grease lubrication, because grease hardens easily, it is very difficult to annotate, often cause the bearing burnout phenomenon, produce serious mechanical accident, the plain bearing bearing is very poor to the sealability of bearing in addition, and water and foreign material enter bearing bore easily, makes very easily corrosion of bearing.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, provide a kind of with oil lubricating and good seal performance, the shaft tail end axle bed system of long service life, improvement is that bearing adopts oil lubricating, lubricant oil is by in the oil filling pipe injection bearing cover, adopt static seal between bearing housing and front and rear cover, be equipped with floating end face mechanical seal spare between bearing housing and rotating shaft head, specifically be achieved like this: improved shaft tail end axle bed system, comprise bearing support, bearing, bearing housing, front and rear cover and the spindle nose that connects with main shaft, it is characterized in that the bearing housing afterbody is provided with oil filling pipe and the oil level scale that communicates with bearing housing inside, be equipped with elastic seal ring between bearing housing and front and rear cover, be provided with floating type mechanical seal friction between bearing housing and spindle nose and pay.The utility model can make bearing turn round in filling with the environment of machine oil, has prolonged the working life of bearing, at the high characteristics of machine oil seal request, adopts standstill seal circle and two kinds of seal form of floating end face mechanical seal spare to guarantee that lubricant oil does not leak.
When the utility model is used on the rotating disk aerator, but be implemented in self-aligning in certain inclined to one side scope, the bearing of tail end axle bed system is selected selfaligning bearing, also can select not aligning but painstaking bigger tapered roller bearing, when using tapered roller bearing, bearing housing must be shelved on the arch nylon lining seat of setting up in the bearing support, also be provided with the location telescopic chute on the bearing housing corresponding with arch nylon lining seat, the surface that nylon lining seat has circular arc, whole bearing is moved axially within the specific limits and bob and weave, realize aligning effect and flexible automatically.
Bearing support of the present utility model is designed to have two-part up and down of tilting or double shape deciliter face, and wherein tilting can make bearing stressed in the running more reasonable even.
Spindle nose of the present utility model connects with main shaft by flange, and when this axle bed system was used on the oxidation ditch aeration machine, the diameter of its main shaft designed between φ 80-φ 600mm, and effect is obvious.
The utility model adopts the oil lubricating bearing just, Sealing by two kinds of forms of sound, sealing is reliable, automatically break-in, long service life cooperates with arch nylon lining seat with tapered roller bearing, can realize aligning, make tail end axle bed system have the center adjusting value of θ≤30 ° and the axial stretching amount of δ≤60mm, make bearing capacity big again.
