Abstract

The utility model relates to a pair roller moulding machine, in particular to a keyless connection structure of the pair roller moulding machine, comprising a transmission shaft and a roller; the transmission shaft is in interference fit with the roller through an inner connection ring and an outer connection ring which are orderly sleeved on the outer surface of the transmission shaft; the inner connection ring and the outer connection ring are connected through a connecting piece in the axial direction; the circumferential direction of the inner connection ring is uniformly distributed with fabrication holes; the outer connection ring is uniformly distributed with grooves in the axial direction; and one of the grooves is through. Compared with the prior art, with the matched inner connection ring and outer connection ring, the keyless connection structure has good centring performance and simple structure; the centring problem of roller ball pit can be better solved by adjusting the relative position of the shaft and the roller in the axial direction and the circumferential direction to improve the ball forming ratio; the keyless connection structure is also provided with a stress concentration source, so the pair roller moulding machine has high bearing capacity; and with fabrication holes arranged on the inner connection ring, the keyless connection structure is convenient to assemble and disassemble.

Description

Keyless connection structure of roller briquetting machine

Technical field:

The utility model relates to a kind of roller briquetting machine, a kind of specifically keyless connection structure of roller briquetting machine.

Background technique:

At present, extensive use roller briquetting machine in coal, the metallurgy industry, the normal key connecting mode that adopts between its transmission shaft and the roll, because it bears moment of torsion, the relative position of roll and transmission shaft changes, and the problem of ball hole dislocation in use often takes place, and mechanical balling ratio is low.

Summary of the invention:

The purpose of this utility model is to overcome the deficiency of background technique and provides a kind of balling ratio high keyless connection structure of roller briquetting machine.

The technological scheme that realizes foregoing invention is:

A kind of keyless connection structure of roller briquetting machine, comprise transmission shaft, roll, inside and outside connection ring body and the described roll interference fit of described transmission shaft by being sleeved on its outer surface successively, both axially connect of described inside and outside connection ring body with link, should be evenly equipped with auxiliary hole on the circumferencial direction of interior connection ring body, the connecting ring axon is to being evenly equipped with groove outside the described edge, and one of them groove is open-minded.

The utility model compared with prior art because uses that cooperatively interact of inside and outside connection ring body, its centering property is good, simple in structure; Vertically and circumferentially the relative position of adjusting axle and roll shop building can better solve the centering problem in roller ball hole, the raising balling ratio; This structure does not have stress raiser, its bearing capacity height; The auxiliary hole that on interior connection ring body, is provided with, for convenience detach.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the side view of Fig. 1.

Embodiment:

Below in conjunction with drawings and Examples in detail the utility model is described in detail:

A kind of keyless structure of roller briquetting machine is by transmission shaft 1, bolt 2, interior connection ring body 3, connect ring body 4, roll 5, auxiliary hole 6, groove 7, groove 8, groove 9 outward and form.

The interior connection ring body 3 and outer be connected ring body 4 and roll 5 interference fit of transmission shaft 1 by being sleeved on its outer surface successively, interior ring body 3 male cone (strobilus masculinus)s that connect match with the inner conical surface that is connected ring body 4 outward, in connect ring body 3 and locate to be connected both axial of ring body 4 with bolts 2 connections, be evenly equipped with auxiliary hole 6 on the circumferencial direction of interior connection ring body 3, axially be evenly equipped with groove 7, groove 8, groove 9 along the outer ring body 4 that connects, wherein groove 7 is a groove.

When the bolt 2 that along the circumferential direction distributes with interior connection ring body 3 and outside when being connected ring body 4 and straining, under the effect of axial clamping force, radial force acts on respectively on transmission shaft 1 and the roll 5 by outer connection ring body 3 and interior connecting ring 4 respectively, the impacting force that between transmission shaft 1 and roll 5, produces, thus drive roll 5 rotations.

Claims (2)

1, a kind of keyless connection structure of roller briquetting machine, comprise transmission shaft, roll, it is characterized in that: inside and outside connection ring body and the described roll interference fit of described transmission shaft by being sleeved on its outer surface successively, both axially connect of described inside and outside connection ring body with link, should be evenly equipped with auxiliary hole on the circumferencial direction of interior connection ring body, the connecting ring axon is to being evenly equipped with groove outside the described edge, and one of them groove is open-minded.

2, keyless connection structure of roller briquetting machine according to claim 1 is characterized in that described outer connecting ring axon is 3 to the groove that is provided with.
