Abstract

The utility model provides a mounting structure for the rear bearing seat and the rear bearing seat base of a brick machine. The mounting structure comprises a main shaft, the rear bearing seat and the a rear bearing seat base, wherein a flanged lip disc is arranged at the front end of the rear bearing seat, a disc groove corresponding to the shape of the flanged lip disc is formed at the front end of the rear bearing seat base, the main shaft penetrates through the rear bearing seat, the rear bearing seat is arranged at the rear bearing seat base in a penetrating manner, and the flanged lip disc and the disc groove are tightly clamped and fixedly connected together. The utility model solves the problems of high probability of stretching deformation in bolts, looseness, breakage, as well as high difficulty and heavy workload in maintenance in the prior art, meanwhile, the normal running of all components inside a main gear case can be well protected, and the maintenance and the mounting to the main shaft are enabled to be more convenient.

Description

The mounting structure of a kind of rear bearing block of brick machine and rear bearing block pedestal

[technical field]

The utility model relates to a kind of structure of brick machine, the mounting structure of particularly a kind of rear bearing block of brick machine and rear bearing block pedestal.

[background technology]

Brick machine main shaft drives through equilateral cross section and is installed in the spiral on the main shaft, pug is advanced to the outlet extruding, thereby produce very big axial force, though this axial force major part has main bearing seat to take, but still some passes on the rear bearing block.At present, brick machine of the prior art is connected with the rear end of bolt with bearing gland and rear bearing block in order to absorb this part axial force.But there is following problem in this kind fixing mechanism: 1, bolt can produce stretcher strain, loosening under the effect of the axial force that changes; Even fracture; And this situation is in case occur; This part axial force on the main shaft will be passed to the main-gear box of rear end through shaft coupling, and axle, gear etc. in the gear-box are caused certain destruction; 2, the relevant parts of main shaft are when dismantling maintenance; Because bearing gland is stuck in the rear end of rear bearing block, main shaft can only shift out backward, and shifting out of main shaft must just can be moved after the main-gear box that is positioned at the rear bearing block back is removed; And main-gear box is very heavy; Mobile need are employed bigger hanging device, and general brick field is not possess this bigger hanging device, have therefore increased maintenance difficulty and workload.

[utility model content]

The technical problem that the utility model will solve is to provide a kind of main shaft of brick machine and the mounting structure of rear bearing block, exists bolt to stretch easily to become row, loosening, fracture and maintenance difficulty big to solve in the prior art this structure, the problem that workload is big.

The utility model is achieved in that a kind of rear bearing block of brick machine and the mounting structure of rear bearing block pedestal; Comprise a main shaft, a rear bearing block and a rear bearing block pedestal; The front end of said rear bearing block is provided with a flange disk, the front end of said rear bearing block pedestal be provided with one with the corresponding disk groove of flange disc-shape, said main shaft passes rear bearing block; Said rear bearing block is located on the rear bearing block pedestal, and the flange disk closely engages with the disk groove and is fixed together.

The advantage of the utility model is: the front end that the flange disk of rear bearing block is arranged on rear bearing block; Front end at the rear bearing block pedestal is provided with a circle disk groove simultaneously; Be used for the snap flange disk; This design can make main shaft pass to the axial force backward on the rear bearing block, through being set in the outside rear bearing block of main shaft, is absorbed by the rear bearing block pedestal that is connected with rear bearing block fully; Thereby well protected the normal operation of each parts in the main-gear box; The I&M of main shaft simultaneously need not the rear gear box of the heavy of rear bearing block back is shifted out backward, as long as main shaft is packed into from the front or pulled out, makes the maintenance of main shaft and installation more convenient.

[description of drawings]

Combine embodiment that the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the structural representation of mounting structure of rear bearing block and the rear bearing block pedestal of a kind of brick machine of the utility model.

Fig. 2 is the profile of rear bearing block of mounting structure of rear bearing block and the rear bearing block pedestal of a kind of brick machine of the utility model.

[specific embodiment]

See also illustrated in figures 1 and 2; The rear bearing block of a kind of brick machine that the utility model is related and the mounting structure of rear bearing block pedestal; Comprise a main shaft 1, a rear bearing block 2 and a rear bearing block pedestal 3; The front end of said rear bearing block 2 is provided with a flange disk 21, the front end of said rear bearing block pedestal 3 be provided with one with the corresponding disk groove 31 of flange disk 21 shapes, said main shaft 1 passes rear bearing block 2; Said rear bearing block 2 is located on the rear bearing block pedestal 3; And flange disk 21 and disk groove 31 closely engage and is fixed together, and this design can make main shaft 1 pass to the axial force backward on the rear bearing block 2, engaged the rear bearing block pedestal 3 that the disk groove 31 that is connected belongs to fully with flange disk 21 through the flange disk 21 on the rear bearing block 2 and absorbs; Thereby well protected the normal operation of each parts in the main-gear box (figure does not show); The I&M of main shaft 1 simultaneously need not the rear gear box of the heavy of rear bearing block pedestal 3 back (figure does not show) is shifted out backward, as long as main shaft 1 is packed into from the front or pulled out, makes the maintenance of main shaft 1 and installation more convenient.

Though more than described the specific embodiment of the utility model; But the technical staff who is familiar with the present technique field is to be understood that; We described concrete embodiment is illustrative; Rather than being used for qualification to the scope of the utility model, those of ordinary skill in the art are in the modification and the variation of the equivalence of doing according to the spirit of the utility model, all should be encompassed in the scope that the claim of the utility model protects.
