Abstract
The utility model relates to an internal mixer rotor positioner belongs to tire production facility field. The bearing positioning sleeve is assembled on a shaft of the internal mixer rotor, a positioning pin mounting hole groove is milled on the bearing positioning sleeve, a positioning pin penetrates through the positioning pin mounting hole groove to assemble the bearing positioning sleeve and the shaft of the internal mixer rotor together, and the end part of the internal mixer rotor is screwed with a locking nut together through threads and is fastened in place through a locking sheet. The utility model has the advantages of simple and reasonable structure, processing simple manufacture eliminates the hidden danger that produces the displacement change between rotor bearing axle sleeve and rotor to strengthen the structural stability of axle sleeve and rotor location, prevented that the axle sleeve is not hard up.
Description
Technical Field
The utility model relates to a tire production facility field says in detail an internal mixer rotor positioner.
Background
As is well known, the existing internal mixer rotor generally adopts a thrust bearing to axially position the internal mixer rotor and has the advantages of simple structure and convenient disassembly and assembly. However, the positioning device only carries out fastening and positioning through the locking nut, the fastening effect is poor, no positioning exists between the rotor positioning sleeve and the rotor of the internal mixer, the positioning sleeve and the rotor are easy to displace, the positioning is invalid, and then the phenomenon of rotor movement is generated.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides an internal mixer rotor positioning device, simple structure is reasonable, and processing simple manufacture eliminates the hidden danger that produces the displacement change between rotor bearing axle sleeve and rotor.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an internal mixer rotor positioner, is equipped with the bearing position sleeve, characterized by, two footstep bearings are installed to the bearing position sleeve outside, assemble the bearing position sleeve to the axle of internal mixer rotor, mill out locating pin mounting hole groove on the bearing position sleeve, the locating pin passes the locating pin mounting hole groove and assembles bearing position sleeve and the axle of internal mixer rotor together, the tip of internal mixer rotor is in the same place through screw thread and lock nut soon and through the stay fastening target in place.
The beneficial effects of the utility model are that, simple structure is reasonable, and processing simple manufacture through the position between positioner locking rotor and the bearing housing, eliminates the hidden danger that produces the displacement change between rotor bearing axle sleeve and rotor to strengthened the structural stability of axle sleeve with the rotor location, prevented that the axle sleeve from becoming flexible.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, an internal mixer rotor, 2, a bearing positioning sleeve, 3, a locking nut, 4, a locking sheet, 5, a thrust bearing and 6, a positioning pin are arranged.
Detailed Description
In fig. 1, the utility model discloses be equipped with bearing position sleeve 2, two footstep bearings 5 are installed in the 2 outsides of bearing position sleeve, assemble bearing position sleeve 2 to banbury mixer rotor 1 epaxially, mill out the locating pin mounting hole groove on the bearing position sleeve 2, locating pin 6 passes the locating pin mounting hole groove with bearing position sleeve 2 with banbury mixer rotor 1's axle assembly together, banbury mixer rotor 1's tip through the screw thread with lock nut 3 screwed together and through the locking plate 4 fastening prevent that lock nut 3 is not hard up in place. When the rotor 1 of the internal mixer and the bearing positioning sleeve 2 rotate simultaneously, the positioning pin 6 ensures the purpose that the bearing positioning sleeve 2 and the rotor 1 of the internal mixer are positioned without looseness.
