Abstract
The utility model relates to a pressure screen with an auxiliary support bearing, which comprises an auxiliary support bearing, a rotor, a main shaft, an upper bearing, a lower bearing and a belt pulley group. Both ends of the main shaft of the pressure screen rotor which is fixedly mounted is equipped with an upper bearing and a lower bearing, and one end which is equipped with the lower bearing is also equipped with a belt pulley. The utility model is characterized in that the cap of the pressure screen main shaft is equipped with the auxiliary support bearing. The pressure screen with an auxiliary support bearing can effectively reinforce the stability of the rotation of the rotor, improve the service span of a bearing in the rotor, reduce maintaining and repairing time, and reduces damage which is caused by swinging the main shaft of a screen basket.
Description
Technical field
The utility model relates to the paper-making pulping filter, especially relates to a kind of pressurized screen with supporting base.
Prior art
Upper and lower two block bearings are all arranged on the main shaft of existing pressurized screen, and the rotor of pressurized screen is contained in the outside of upper support bearing fulcrum, form the structure of cantilever beam, when equipment turns round for a long time, because the influence of the belt pulley radial effect power of lower bearing one end, lower bearing is vulnerable to wobbler action than upper bearing (metal), makes lower bearing cause uneven wear easily, thereby cause the swing of main shaft and rotate instability, to such an extent as to damage screen cylinder.
Summary of the invention
The purpose of this utility model is to solve the shortcoming that prior art exists, and provides a kind of pressurized screen device that reduces the band aiding support bearing of pressurized screen main shaft uneven wear, to prevent causing spindle swing to damage screen cylinder because of the uneven wear of lower bearing.
For achieving the above object, the technical solution adopted in the utility model is to realize like this, a kind of pressurized screen with the aiding support bearing, it is made up of aiding support bearing, rotor, main shaft, upper bearing (metal), lower bearing, belt pulley, upper bearing (metal) and lower bearing are equipped with in the main shaft two ends of fixed installation pressure sieve rotor, in the outer end that lower bearing is housed belt pulley is housed also, the prolongation termination of described pressurized screen main shaft is equipped with the aiding support bearing.
The utility model compared with prior art can effectively strengthen the stationarity of rotor rotation, improves the life-span of bearing, reduces and safeguards and maintenance time, reduces screen cylinder owing to spindle swing damages.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
The specific embodiment
Now 1 the utility model is described in further detail in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of pressurized screen with the aiding support bearing, it is made up of aiding support bearing 1, rotor 2, main shaft 4, upper bearing (metal) 3, lower bearing 5, belt pulley 6, upper bearing (metal) 3 and lower bearing 5 are equipped with in main shaft 4 two ends of fixed installation pressure sieve rotor 2, in the outer end that lower bearing 5 is housed belt pulley 6 is housed also, the prolongation termination that it is characterized in that pressurized screen main shaft 4 is equipped with aiding support bearing 1, and aiding support bearing 1 adopts the mode of radial floating and axial restraint.Radial floating is that the bearing block that aiding support bearing 1 is housed adopts matched in clearance to install, and axially uses nut rigid bearing inner ring.
Another embodiment of the present utility model prolongs the termination at two of main shaft 4 aiding support bearing 1 respectively is installed, and bearing adopts double-row radial ball bearing, and the diameter of axle is 50mm, and homemade model is 1510, appearance and size 50 * 90 * 23, and the bearing two ends can have seal cover.
