Abstract

The utility model relates to a shaft coupling, which is characterized in that a reception disc (1) and a reception disc (6) of the shaft coupling are connected with a middle disc (5) through bolts. Two bolts (2, 2') (3, 3') are respectively fixed on the reception discs (1) (6). The reception discs (1) (6) at both ends and the middle disc (5) are assembled into a whole body through the two pairs of bolts. The four bolts are distributed in a cross mode. The design can eliminate the phenomenon that machinery parts are damaged due to the coaxality errors between two mills. An even transmission speed can be offered. A vibration damping effect is good.

Description

A kind of coupling

A kind of coupling relates generally to the flour working machine.

In the prior art, middle-size and small-size flour working machine transmission of power adopts the concentrated transmission mode mostly, and this kind of drive is convenient to user's maintenance, and management and complete machine cost also the flour working machine than a machine one mill are cheap.But concentrated transmission mode sixty-four dollar question is that coaxality requires very high between mill and the mill.For example: Qingdao is produced DFT-20 profile powder complete equipment for processing and is adopted double row (four skin four-cores) concentrated transmission mode exactly, and adopts joint arrangement as the coupling between two mills.Find that by using there are a lot of problems in this hitch bar; The first, it is very strict to adopt universal joint to require as the coaxality between coupling two mills, and this is difficult to reach for general individual individual workship; The second, universal joint is a rigid joint, and it is very difficult that bigger transmitting torque is depended merely on the wheel gum cover is cushioned between motor and the mill; Three, use a universal joint to be difficult to obtain uniform transmission speed between the diaxon.Owing to there are the problems referred to above, often go out grinding roller spindle nose, flange plate damage, the key phenomenon also often appears rolling.

The purpose of this utility model provides a kind of coupling, solving the above-mentioned problem that exists, reduces the damage of machinery and other part, prolongs machine working life.

The utility model is to realize like this, a kind of coupling, it is characterized in that: the connecing dish 1, connect dish 6 and connect with disk 5 of coupling by bolt, be fixed with two bolts (2 respectively on 1,6 connecing dish, 2 ') (3,3 '), and two ends connect the dish 1,6 and disk 5 be one by above-mentioned two pairs of bolts assemblies, its four bolts become spider to distribute, 90 ° of distributions.

Disk of the present utility model is the rubber plate of middle clamp, and optimum thickness is 5～15 millimeters.

The dish (1) that connects of the present utility model is at least 80 millimeters to the distance that connects dish (6).

This coupling is compared with coupling of the prior art a lot of good effects, the available technology adopting universal joint is as coupling, corner is very little, if the diaxon coaxality has deviation slightly, the dead angle just may occur and cause the grinding roller spindle nose to damage in transmission process, and roll key phenomenon especially severe, novel coupling is because the centre adopts rubber plate as disk, increased angle range, both made coaxality have deviation also can not produce big influence slightly.Director each of machine working life of part in addition.

Accompanying drawing has been represented a kind of embodiment of coupling.

Below with reference to the accompanying drawings embodiment is described:

Coupling of the present utility model is as shown in Figure 1: form by connecing dish (1), bolt (2,2 ') (3,3 '), disk (5) and connecing dish (6).Connect dish (1), connect dish (6) and can manufacture with the steel plate of 12 millimeters thick; Disk (5) can be manufactured with the rubber plate of the center clamp of 5～10 millimeters thick.Considering that problem such as I﹠M will connect dish (1) and connect dish (6) outer end is processed as the flange plate of plane and two between grinding and joins, and owing to the close installation dimension that connects dish (1) one end is less, four bolts hole that will connect dish (1) are split into gap (7).Connect dish (1) and remove four and the joining hole of flange plate, in addition two pairs of bolts (2,2 ') (3 with connecing dish (6), 3 ') be welded on respectively and connect on the dish (1,6) two termination dishes (1,6) pass through bolt (2 with disk, 2 ') (3,3 ') be connected as one, its four bolts become a spider of 90 ° of distributions, when machine run, if the diaxon coaxality has the disk of this coupling of deviation just can eliminate, and transmission speed also relatively evenly, and buffer shock-absorbing is effective.

This coupling is reasonable in design, simple in structure, easy manufacturing, and middle-size and small-size processing factory of mechanism all can make.The hitch bar that this coupling also can be used as in other machinery uses, and China town and country collective and individual flour mill are quite general at present, and this coupling has certain popularization value.
