Description
Technical field
The utility model relates to a kind of new type of safe coupling, can be widely used between motor and speed reducer or need protection transmission device between connection.
Background technique
Main transmission coupling in rolling mill production line and seamless steel tube production chain between motor and speed reducer generally needs to possess safe shearing function; when working when torque overload like this in the operation of rolling or occur other burst accidents; safety coupling can cut off safety pin in time; interrupt torque transmitting, thus available protecting motor and roll and relevant device thereof.Safety coupling is able to extensive use in the similar operating condition occasion such as main mill and leveler that is cold rolling, seamless steel tube production chain.
Existing cold rolling main transmission safety coupling structure is as shown in Figure 2: motor side axle sleeve 14 is arranged on motor output shaft, mandrel 15 is fixed on motor side axle sleeve 14 by screw 19, connecting flange 16 is fixed on (connecting flange 16 and mandrel 15 can relatively rotate) on mandrel 15 by bearing 9, locking nut 8, gland 6, connecting flange 16 is connected with ring gear 17 by gear pair 18, ring gear 17 is connected with speed reducer end half-coupling 2 by attachment bolt 7, and half-coupling 2 is arranged on speed reducer input shaft.Motor side axle sleeve 14 is connected with transmitting torque with connecting flange 16 by safety pin 13, safe guide 12, nut 10.
Safety coupling in use, if bearing 9, screw 19, locking nut 8 are damaged, by safety coupling structural limitations, must remove motor or speed reducer just can dismantle the above part of damage of safety coupling maintain and replace.And after having keeped in repair, also need again accurate adjustment motor and speed reducer coaxality; demolition, repair, replacement, recovery need to shut down at least 48 hours; only cannot directly have a strong impact on milling train manufacturing efficiency by dismounting safety coupling with regard to replaceable damage parts; add maintenance labor intensity, can not meet the requirement that modern metallurgical production line rolls safety coupling continuously.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel safety coupling; its motor side, speed reducer end all adopt half-coupling; safe shearing function is realized by the safety component of centre; security component can be dismantled online, change; both time saving and energy saving, do not need again again accurate adjustment motor and speed reducer coaxality, effectively can shorten Maintenance Downtime; reduce maintenance labor intensity, meet the requirement of milling train continuous operation.Meanwhile, the utility model shortens engineering time, ensure that production is carried out smoothly, creates benefit.
A kind of novel safety coupling of the utility model, it comprises speed reducer end half-coupling, it also comprises motor side half-coupling, be arranged between motor side half-coupling and speed reducer end half-coupling with the dismountable safety component be both connected.
Dismountable safety component comprises the first duplex flange, the second duplex flange, mandrel, safety pin, safe guide; Connected by safety pin between first duplex flange with the second duplex flange, safety pin is contained in safe guide, and passes through nut check; Between first duplex flange and the ring gear of motor side half-coupling, the second duplex flange all connected by attachment bolt with between the ring gear of speed reducer end half-coupling; Mandrel is arranged on the inside of the first duplex flange and the second duplex flange, and its left side is fixedly connected by screw and the first duplex flange, and intermediate portion matches with the endoporus of the first duplex flange, is provided with bearing between right section and the endoporus of the second duplex flange.
Safety component during this is novel is connected with motor side half-coupling, speed reducer end half-coupling by connecting bolt.Like this, when this novel safety coupling in use, if bearing, screw, locking nut are damaged, only need to remove attachment bolt, just safety component entirety can be unloaded renewal part, namely can change the part of damage online and motor or speed reducer need not be removed, both engineering time is shortened like this, reduce maintenance labor intensity, improve efficiency, meet the requirement of continuous-rolling work characteristics, do not need again to make again accurate adjustment motor and speed reducer coaxality, ensure that the operating accuracy of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of this new type of safe coupling.
Fig. 2 is the structural representation of existing safety coupling.
Embodiment
As can be seen from Figure 1, the utility model safety coupling, it comprises speed reducer end half-coupling 2, it also comprises motor side half-coupling 1, be arranged between motor side half-coupling 1 and speed reducer end half-coupling 2 with the dismountable safety component be both connected.
Wherein, dismountable safety component comprises the first duplex flange 3, second duplex flange 5, mandrel 4, safety pin 13, safe guide 12; Connected by safety pin 13 between first duplex flange 3 with the second duplex flange 5, safety pin 13 is contained in safe guide 12, and is locked by nut 10; All connected by attachment bolt 7 between first duplex flange 3 and the ring gear of motor side half-coupling 1, between the second duplex flange 2 with the ring gear of speed reducer end half-coupling 2; Mandrel 4 is arranged on the inside of the first duplex flange 3 and the second duplex flange 5, its left side is fixedly connected by screw 11 and the first duplex flange 3, intermediate portion matches with the endoporus of the first duplex flange 3, is provided with bearing 9 between right section and the endoporus of the second duplex flange 5.Wherein, the Internal and external cycle of bearing 9 is fixed on mandrel 4 respectively by locking nut 8, gland 6.When there is torque overload or other burst accidents in the operation of rolling, safety coupling can cut off safety pin 13 in time, interrupts torque transmitting, thus available protecting motor and roll and relevant device thereof.
Compared with this novel and existing safety coupling, its structural change is: safety component is connected with motor side half-coupling 1, speed reducer end half-coupling 2 by connecting bolt 7; Connected by safety pin 13 between first duplex flange 3 with the second duplex flange 5.Like this, when this novel safety coupling in use, if when the part in the safety components such as bearing 9, locking nut 8 is damaged, only need to remove attachment bolt 7, just safety component entirety can be unloaded, online change damage part and motor or speed reducer need not be removed, both engineering time is shortened like this, reduce maintenance labor intensity, improve efficiency, meet the requirement of continuous-rolling work characteristics, do not need again to make again accurate adjustment motor and speed reducer coaxality, ensure that the operating accuracy of equipment.
This novel safety coupling design is ingenious, and convenient disassembly, efficiently solves the problem of the replacing inconvenience that existing safety coupling exists, successful.
