Abstract
The utility model discloses a deep cone thickener main shaft seat, wherein two bearings are mounted in a bearing chamber of the main shaft seat from top to bottom in interference fit, and a spacing sleeve is arranged between the two bearings. The spacing sleeve comprises an inner spacing sleeve and an outer spacing sleeve, wherein a gap is left between the inner spacing sleeve and the outer spacing sleeve, the inner spacing sleeve is pressed on the inner circles of the two bearings, and the outer spacing sleeve is pressed on the outer circles of the two bearings. A thrust bearing is mounted in either of the two bearings, which is arranged on the lower portion. The deep cone thickener main shaft seat is provided with the inner spacing sleeve and the outer spacing sleeve between the two bearings, and the inner spacing sleeve and the outer spacing sleeve are coaxial, and a gap is left between the inner spacing sleeve and the outer spacing sleeve, and the inner spacing sleeve and the outer spacing sleeve are respectively supported on the inner circles and the outer circles of the two bearings. The deep cone thickener main shaft seat not only can guarantee the normal operation of the bearing, but also can avoid the circumstance of failure because a main shaft drops from happening.
Description
Technical field
The utility model relates to the thickner field, especially relates to a kind of main shaft seat that is used for deep cone thickener.
Background technique
Two cover bearings are installed up and down in the main shaft seat bearing chamber of existing deep cone thickener, at regular intervals between the two cover bearings.And when damage of bearings, main shaft can move down thereupon falls the thickner bottom, and the coupling that causes being connected with main shaft breaks away from, and bottom rake frame kills and can not move, and causes fault to stop production.
Such structure also makes and mainly being born by bearing of main shaft and the gravity of harrowing frame makes bearing reduction in working life.
The model utility content
The purpose of this utility model is to provide a kind of deep cone thickener main shaft seat and deep cone thickener, and in the working life of lengthening bearing, main shaft drops and causes the generation that stops production when preventing damage of bearings.
The technical solution of the utility model is:
A kind of deep cone thickener main shaft seat, in the bearing chamber of main shaft seat from top to bottom interference fit two bearings are installed, between described two bearings, be provided with spacer sleeve.
Spacer sleeve and outer spacer sleeve in described spacer sleeve is divided into have between interior spacer sleeve and the outer spacer sleeve at interval, and described interior spacer sleeve withstands on the inner ring of two bearings, and described outer spacer sleeve withstands on the outer ring of two bearings.
Under the bearing below being positioned in described two bearings thrust-bearing is installed.
The utility model is by spacer sleeve in being provided with between two bearings and outer spacer sleeve, and interior spacer sleeve and outer spacer sleeve are coaxial and the interval is arranged each other, are supported on respectively on the Internal and external cycle of two bearings.Can guarantee that bearing runs well, also can avoid occurring taking place because of main shaft falls to causing the situation of fault.Increase thrust-bearing under the bearing below in bearing chamber, main shaft and rake frame weight are released in above the thrust-bearing, alleviate the axial gravity of top two bearings, thereby prolong the working life of bearing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, be set with two bearings 1 and 2 on the main shaft 6 in the main shaft seat, bearing 1 and 2 is single-row angular contact bearing, in between bearing 1 and 2, being provided with spacer sleeve 3 and outside spacer sleeve 4, interior spacer sleeve 3 and outer spacer sleeve 4 are coaxial and the interval is arranged each other, are supported on respectively on the Internal and external cycle of bearing 1 and 2.Can guarantee that bearing runs well, also can avoid occurring the situation generation that main shaft falls to breaking down.
At the bearing chamber inner bearing 2 following thrust-bearings 5 that increase, main shaft 6 and rake frame weight are released in above the thrust-bearing 5, alleviate the axial gravity of top two bearings 1,2, thereby prolong the working life of bearing 1,2.
Claims (3)
1, a kind of deep cone thickener main shaft seat, in the bearing chamber of main shaft seat from top to bottom interference fit two bearings are installed, it is characterized in that: between described two bearings, be provided with spacer sleeve.
2, deep cone thickener main shaft seat according to claim 1, it is characterized in that: spacer sleeve and outer spacer sleeve in described spacer sleeve is divided into, have between interior spacer sleeve and the outer spacer sleeve at interval, spacer sleeve withstands on the inner ring of two bearings in described, and described outer spacer sleeve withstands on the outer ring of two bearings.
3, deep cone thickener main shaft seat according to claim 1 and 2 is characterized in that: under the bearing below being positioned in described two bearings thrust-bearing is installed.
