Abstract
The utility model discloses a suspension structure for a mixer shaft, which comprises a charging barrel and a mixer shaft positioned in the charging barrel, wherein the outer top surface of the charging barrel is fixedly connected with a lower bearing block; the top surface of the lower bearing block is connected with a detachable upper bearing block; the upper end section of the mixer shaft penetrates out of the upper bearing block through inner cavities of the lower bearing block and the upper bearing block; a lower bearing assembled in the lower bearing block, and an upper bearing assembled in the upper bearing block are sheathed on the mixer shaft; and the mixer shaft is screwed with a locking nut which is positioned above the lower bearing and used for axially locking the lower bearing. The suspension structure has the advantages of low bearing abrasion and long service life, is convenient for maintenance, and can enhance the production efficiency and lower the production cost.
Description
Technical field
The utility model relates to mixing plant, is specifically related to the syndeton of vertical mixing plant shaft.
Background technology
Vertical mixing plant comprises barrel and shaft, and the connected mode of shaft and barrel mainly contains following two kinds.The one, inboard interconnection system, promptly shaft is connected on the barrel through the bearing block that is fixed on the barrel inner top surface, and material gets in the bearing block easily, causes bearing wear bigger, and shorten service life, and inboard interconnection system also brings the shortcoming of inconvenient maintenance.The 2nd, the both sides connected mode; Be that shaft is connected on the barrel through two bearing blocks that are fixed on outer end face of barrel and the outer bottom; Though can not advance material in this kind mode upper axis bearing, still advance material easily in the bearing block of bottom, the bearing of bottom still weares and teares bigger.Material is not only the wearing and tearing that strengthened bearing after getting in the bearing block, and too much the entering of material also can cause the bearing clamping stagnation.
Summary of the invention
The technical problem that the utility model will solve provides the suspended structure of a kind of bearing wear shaft little, easy to maintenance.
In order to solve the problems of the technologies described above; The utility model provides a kind of suspended structure with shaft of following structure; Comprise barrel and the shaft that is positioned at barrel; Its design feature is to be connected with step on the outer end face of said barrel, is connected with dismountable top chock on the end face of step, and the upper end section of shaft is passed step and top chock inner chamber and passed top chock; Be set with the lower bearing that is assemblied in the step on the shaft and be set with the upper bearing (metal) that is assemblied in the top chock, be bolted with on the shaft and be positioned at the lower bearing top and be used for the axial locking nut of locking of lower bearing.
The internal diameter of said upper bearing (metal) is less than the internal diameter of lower bearing.
Be bolted with the screw that ejects that can contact on the bottom surface of said step with the lower surface, outer ring of lower bearing.
Be provided with sealing ring between the top of said top chock and the shaft, be provided with lower seal between the bottom of step and the shaft.
The utility model is realized being connected of shafts and barrel through being located at two bearing blocks and two bearings on the outer end face of barrel; Make the material of barrel be difficult to enter in the bearing block; Prevent bearing clamping stagnation and the wearing and tearing that reduced bearing, prolonged the service life of bearing, reduced maintenance frequency; Prolonged maintenance cycle, correspondingly improved production efficiency and reduced production cost.Lower bearing in the two bearings plays the location and bears the effect of axial force, promptly in to the shaft radial location, also shaft is hung in the barrel, and upper bearing (metal) only carries out radial location, and the setting of two bearings can be eliminated beating in the shaft rotation process.The dismountable connected mode of top chock makes that maintenance is convenient.
In sum, the advantage of the utility model is little, the long service life of bearing wear, and is easy to maintenance; Can bring the beneficial effect of enhancing productivity and reducing production costs.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; The suspended structure of shaft comprises barrel 1 and the shaft 12 that is positioned at barrel 1; Be connected with step 2 on the outer end face of barrel 1, be connected with top chock 3 through bolt on the end face of step 2, the upper end section of shaft 12 is passed step 2 with top chock 3 inner chambers and pass top chock 3; The traversing through end of shaft 12 is used for being connected with drive unit power, and drive unit is made up of motor 10 and reduction box 11.Shaft 12 is positioned on portion's section of step 2 and top chock 3 and is set with lower bearing 4 and the upper bearing (metal) 5 that is provided with at interval; Lower bearing 4 is contained in bottom in the step 2; Upper bearing (metal) 5 is contained in the internal upper part of top chock 3; The spacing distance that is to say two bearings will be tried one's best greatly, can reduce radially wobbling of shaft greatly like this.Be bolted with the locking nut 6 that is positioned at lower bearing 4 tops on the shaft 12, locking nut 6 is used for lower bearing 4 is locked in shaft, connects with the suspension that realizes shaft.
For the ease of maintenance or replacing bearing; The internal diameter of upper bearing (metal) 5 is less than the internal diameter of lower bearing 4; Be bolted with on the bottom surface of step 2 can contact with the lower surface, outer ring of lower bearing 4 eject screw 7, the screw 7 that ejects capable of using ejects lower bearing 4 during dismounting in the bearing chamber of step 2.In order to seal, be provided with sealing ring 8 between the top of top chock 3 and the shaft 12, be provided with lower seal 9 between the bottom of step 2 and the shaft 12.
Consider the difference of role, upper bearing (metal) adopts ball bearing, and lower bearing adopts can bear the roller bearing of axial force.
Claims (4)
1. the suspended structure of a shaft; Comprise barrel (1) and be positioned at the shaft (12) of barrel (1); It is characterized in that being connected with step (2) on the outer end face of said barrel (1); Be connected with dismountable top chock (3) on the end face of step (2); The upper end section of shaft (12) is passed step (2) and top chock (3) inner chamber and is passed top chock (3); Be set with the lower bearing (4) that is assemblied in the step (2) on the shaft (12) and be set with the upper bearing (metal) (5) that is assemblied in the top chock (3), be bolted with the locking nut (6) that is positioned at lower bearing (4) top and is used for lower bearing (4) is axially locked on the shaft (12).
