Description
Technical Field
The utility model belongs to the metallurgical equipment field specifically is an improvement structure of transmission shaft coupling.
Background
At present, most of common motor transmission devices adopt a motor to drive a speed reducer to rotate, and the speed reducer and a roller are connected and rotated through a universal coupling. The universal coupling between the speed reducer and the roller is fixedly connected through an output end connecting flange on the speed reducer and a connecting flange on the roller. However, in the actual use process, the coupler at the output shaft end of the speed reducer on the centering device is in interference fit, the interference fit belongs to one of tight fit, namely the size of the matched shaft neck is larger than the size of the hole diameter, so that inconvenience is caused when the coupler is disassembled, the difficulty and time required for replacing the speed reducer at the part are increased, and the downtime is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's weak point, provide a rational in infrastructure, operation stability, convenient to detach, labour saving and time saving's transmission shaft coupling's improvement structure.
The utility model provides a its technical problem take following technical scheme to realize:
the utility model provides an improvement structure of transmission shaft coupling, includes motor, speed reducer, shaft coupling, universal joint and stop screw, the drive shaft coaxial arrangement speed reducer of motor, the output shaft installation shaft coupling of speed reducer, bolted connection universal joint's one end is passed through to the output of shaft coupling, and universal joint's the other end passes through the axial one end of flange joint roller, its characterized in that: the diameter of a central mounting hole of the coupler is larger than that of an output shaft of the speed reducer, a plurality of radial bolt holes are formed in the middle of the coupler, limiting screws are mounted in the radial bolt holes, and the limiting screws penetrate through the coupler in the radial direction and are embedded into the output shaft of the speed reducer.
And a plurality of radial bolt holes of the coupling are uniformly distributed on the middle part of the coupling for a circle.
And the bolts for connecting the coupling and the universal coupling are a plurality of bolts which are annularly and radially and uniformly distributed.
The utility model has the advantages that:
the utility model discloses a what the shaft coupling adopted is transition fit, that is to say the axle journal size is greater than or equal to the aperture size, comes fixed position through positioning bolt and speed reducer axle journal on the shaft coupling, only needs to dismantle positioning bolt when dismantling the shaft coupling, just can easily dismantle centering device's shaft coupling, has reduced the down time of equipment, has improved equipment start time, has improved the productivity of equipment.
