Abstract
The utility model discloses a limit moment coupler locking device, and relates to mechanical general component couplers, in particular to the limit moment coupler locking device which is provided with a locking nut (1) and reverse pre-tightening screws (2). The locking nut (1) is installed on a coupler and abuts against annular leaf springs (3). The limit moment coupler locking device is characterized in that 3-9 screw holes are formed in the side face of the locking nut, and the reverse pre-tightening screws are installed inside the screw holes and abut against the annular leaf springs through the locking nut. The limit moment coupler locking device has the advantages of reducing the amount of maintenance work and improving the working efficiency.
Description
Technical field
The utility model relates to mechanical spare part in common use coupling, belongs to especially a kind of limiting torque coupling locking device.
Background technique
Limiting torque coupling is widely used at present in harbour, mining equiment.As door machine, stacker-reclaimer.Generally to have motor, speed reducer, break to be used in combination together.Revolution electromagnetic brake is arranged on motor upper end, and when motor braking or reversion, because top driving mechanism rotator inertia is huge, rotating speed reduces suddenly, produces very large torsional moment, by speed reducer small gear, acts on limiting torque coupling, to reduce torsional moment.In use often occur that locking nut is loosening, can cause friction plate failure mode, need a large amount of maintenance works, simultaneously because not playing a protective role, make other coupled device damage, have a strong impact on working efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of limiting torque coupling locking device, to reach, reduces maintenance, repair work, the object of increasing work efficiency.
Limiting torque coupling locking device provided by the utility model, there is locking nut and reverse pretension screw, locking nut is arranged on coupling, withstand annular spring leaf, it is characterized in that, locking nut side is provided with 3-9 screw hole, and oppositely pretension screw is arranged in screw hole, and withstands on annular spring leaf through locking nut.
Limiting torque coupling locking device provided by the utility model, be provided with reverse pretension screw, can increase the pressure to annular spring leaf, its reaction force plays the effect of reverse pretension to locking nut, make locking nut be not easy to become flexible, and by the reinforcing to annular spring leaf, increase the frictional force of friction plate.Therefore, the utlity model has the good effect that reduces maintenance, repair work and increase work efficiency.
Accompanying drawing explanation
Accompanying drawing partly discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model structural representation;
Fig. 2, the utility model left side view.
Embodiment
As shown in the figure, limiting torque coupling locking device provided by the utility model, there is locking nut 1 and reverse pretension screw 2, locking nut is arranged on coupling, withstand annular spring leaf 3, locking nut side is provided with 6 screw holes, and oppositely pretension screw is arranged in screw hole, and withstands on annular spring leaf through locking nut.
Limiting torque coupling locking device provided by the utility model, be provided with reverse pretension screw, can increase the pressure to annular spring leaf, its reaction force plays the effect of reverse pretension to locking nut, make locking nut be not easy to become flexible, and by the reinforcing to annular spring leaf, increase the frictional force of friction plate.Greatly reduce friction plate sipping fault, so generally substantially need not maintain; Due to the reduction of the number of times that skids, avoided the accidental damage of speed reducer and motor, the safety of equipment is played a very good protection.
