Abstract
The utility model relates to a sand sorting machine shaft end with a novel sealing device, and belongs to the technical field of sealing of sand sorting machines. The sand sorting machine shaft end comprises a positioning sleeve, a sealing piece, a centering ball bearing arranged outside a shaft end body and a thrust ball bearing arranged inside the shaft end body, wherein the sealing piece and the positioning sleeve are arranged between a bearing pedestal and a supporting seat. According to the sand sorting machine shaft end, a lip-shaped seal of a three-belt framework is adopted, so that the service life is long, and the reliability is high; bearing lubrication oil can be prevented from leaking, and thin sand in sewage can be effectively prevented from entering the bearings; due to the centering ball bearing and the thrust ball bearing, stress on a spiral conveying shaft can be balanced, the stress situation of each seal can be improved, and the service life and the reliability of the seal are improved; and the sand sorting machine shaft end has a simple structure, a good sealing effect, long service and high practicability.
Description
Technical field
The utility model relates to a kind of sub-sand arbor end, specifically is a kind of sub-sand arbor end with new type sealing device, belongs to sub-sand secret encapsulation technique field.
Background technique
The sub-sand machine is the isolated plant that is used to recycle cleaning sullage in the truck mixer jar, and its screw conveyor shaft is inclined among the housing, and two ends are bearing on the housing wallboard through bearing.For preventing that cleaning sullage in the housing to the influence of bearing, need install sealing additional; The sealing that one grease-proof that be merely existing seal arrangement leaks and bilge water resisting get into the felt collar of bearing, and its working life is short, and sealing reliability is poor, and the fine sand in the sewage is prone to get into bearing and makes the bearing can't proper functioning very soon.
Summary of the invention
To the problem that above-mentioned existing technology exists, the utility model provides a kind of sub-sand arbor end with new type sealing device, can improve the working life and the reliability of sealing.
To achieve these goals; The technological scheme that the utility model adopts is: a kind of sub-sand arbor end with new type sealing device, comprise setting sleeve, and also comprise Sealing; Be installed in the selfaligning ball bearing of axle head body exterior, and the thrust ball bearing that is installed in the axle head body interior; Sealing and setting sleeve are installed in the inside between bearing support and the bearing;
Further, setting sleeve is a sleeve shape structure;
Further, Sealing is the lip seal of band skeleton;
Further, Sealing has three, and the lip of left side Sealing is facing to the axle that holds on the left side, and the lip of two Sealings on centre and the right all to the right;
Further, the inner ring of selfaligning ball bearing positions through the shoulder on elastic scheibe and the screw conveyor shaft.
The beneficial effect of the utility model is: this device adopts the lip seal of three road band skeletons, long service life, and reliability is high, both can prevent leaking of bearing grease, also can effectively avoid the fine sand in the sewage to get among the bearing; Adopt selfaligning ball bearing and thrust ball bearing, but the good screw conveyor shaft of balance is stressed, improves force-bearing situation of each sealing, improve sealing working life and reliability.It is simple in structure, good sealing effect, and long service life has practicability widely.
Description of drawings
Fig. 1 is the utility model overall structure schematic representation.
Among the figure: 1, axle head body; 3, selfaligning ball bearing; 31, thrust ball bearing; 5, Sealing; 6, setting sleeve.
Embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
As shown in Figure 1, a kind of sub-sand arbor end with new type sealing device comprises selfaligning ball bearing 3, thrust ball bearing 31, Sealing 5, setting sleeve 6 and supporting base assembly.Said supporting base assembly comprises bearing support, bearing and end cap, and bearing is fixed in the sub-sand engine housing cinclides, and jack shaft is to being processed with the through hole that is used to install screw conveyor shaft and sealing; In the outside of bearing, jack shaft is used for bearings mounted through hole to processing to bearing support, radially is processed with the greasing passage through screw, and there is end cap the left part through screw, adds asbestos packing therebetween.
Said Sealing 5 and setting sleeve 6 are installed in the inside between bearing support and the bearing; Wherein setting sleeve 6 is a sleeve shape structure, and Sealing 5 has three, is the lip seal of band skeleton; The lip of left side sealing is facing to the axle that holds on the left side, and the lip of two sealings on centre and the right all to the right.
Said selfaligning ball bearing 3 is installed in axle head body 1 outside, and thrust ball bearing 31 is installed in axle head body 1 inside; The inner ring of selfaligning ball bearing 3 positions through the shoulder on elastic scheibe and the screw conveyor shaft.
The utility model can prevent that at work bearing grease from leaking, and has avoided the fine sand in the sewage to get among the bearing effectively; Through selfaligning ball bearing 3 and thrust ball bearing 31, balance screw conveyor shaft stressed improves force-bearing situation of each sealing, improves sealing working life and reliability, and it is simple in structure, good sealing effect, and long service life has practicability widely.
