Description
Technical field
The utility model relates to a kind of coupling, particularly a kind of coupling that connects speed reducer and main shaft of hoister.
Background technique
At present domestic at cement industry gradually to the development of aspects such as large-scale, energy-saving and environmental protection, benefit because the large-scale production line construction needs conveying capacity big, the lifting height height, reliable conveying equipment adapts to supporting with it.Domestic existing supporting noria specification is increasing, and corresponding speed reducer specification is also increasing.At present speed reducer and main shaft of hoister connecting mode mainly contain four kinds: 1. hollow shaft+shrink disk connecting mode, 2. hollow shaft+key connecting mode, 3. elastic coupling flexible coupling connecting mode, 4. big minor sprocket connecting mode.Below the pluses and minuses of above-mentioned four kinds of connecting modes are done explanation down:
1. hollow shaft+shrink disk connecting mode
Advantage: structure is compact, and cantilever moment is less, and drive unit integral body is floating type.
Shortcoming: speed reducer connects because of adopting shrink disk, unclamps shrink disk, through regular meeting drive unit is not torn open not got off, and can only pull down with drive unit spindle mounted from tens meters eminence integral body, extrudes with oil hydraulic press.Therefore speed reducer keeps in repair, changes very difficulty, all can not press with oil hydraulic press during exceptional hardship, can only ruin main shaft, the big even directly influence production of workload.
2. hollow shaft+key connecting mode
Advantage: structure is compact, and cantilever moment is less, and drive unit integral body is floating type.
Shortcoming: speed reducer is because of long key connecting, and often drive unit is not torn open not got off, and can only pull down with drive unit spindle mounted from tens meters eminence integral body, extrudes with oil hydraulic press.Therefore speed reducer maintenance, change very difficulty, workload influences production until direct greatly.
3. elastic coupling flexible coupling connecting mode
Advantage: maintenance main shaft of hoister and speed reducer are convenient.
Shortcoming: the elastic coupling flexible coupling volume is bigger, and drive arrangement needs bigger mountion plate.
4. big minor sprocket connecting mode
Advantage: drive arrangement is more flexible, and maintenance main shaft of hoister and speed reducer are convenient.
Shortcoming: because big minor sprocket all is arranged in parallel, between big minor sprocket radial component is arranged when transmitting torque, vibrate during the drive unit operation so bigger, bigger as Transmitted chains and sprocket wheel abrasion after vibration, the accident that easily produces chain rupture, pulls open speed reducer.
This shows that all there is complex structure in above-mentioned four kinds of connecting modes, fragile, working life is shorter, the shortcoming of maintain and replace easily damaged parts difficulty, inconvenience.
Summary of the invention
The utility model provides a kind of simple and practical, long service life at above-mentioned the deficiencies in the prior art, and maintain and replace easily damaged parts coupling easily.
The technical solution of the utility model is achieved in that
A kind of coupling, comprise main shaft shaft coupling halfbody and speed reducer shaft coupling halfbody, end at main shaft shaft coupling halfbody is provided with shrinkage pool, end at speed reducer shaft coupling halfbody is provided with the boss that matches with shrinkage pool, the front end of boss has tapering, main shaft shaft coupling halfbody is provided with this end of shrinkage pool and this end that speed reducer shaft coupling halfbody is provided with boss has flange plate respectively, is provided with the corresponding attachment hole in several positions on flange plate.
In order to ensure the requirement of main shaft and drive unit coaxality, as preferably, described shrinkage pool and boss are transition fit.
As preferably, on attachment hole, be equipped with the tensioner pin, on the tensioner pin, be with the tensioner cover, an end of tensioner pin is formed with the section of being threaded, and is equipped with nut on the described section of being threaded.Thus, the assembling deviation the when linkage structure of tensioner shell type can be eliminated the making of shaft coupling attachment hole guarantees that each hole and cover are evenly stressed, improves the anti-shear ability of fastening piece simultaneously, makes manufacturing, installation, replacing that a lot of convenience are provided again.Fastening nut tensioner bearing pin increases tensioner cover external diameter to moving, until with shaft coupling halfbody hole drive fit.
For preventing flange plate surface damaged, as preferably, between nut and adjacent flange plate, be provided with packing ring.
Adopted the advantage that the utlity model has of technique scheme to be: the front end of the boss of this structure coupling has tapering, makes that by tapering the transfiguration of assembling centering is easy between drive unit and main shaft.The shrinkage pool of shaft coupling and boss are transition fit, have guaranteed main shaft and the requirement of drive unit coaxality.Assembling deviation when the linkage structure of tensioner shell type can be eliminated the making of shaft coupling attachment hole guarantees that each hole and cover are evenly stressed, improves the anti-shear ability of fastening piece simultaneously, makes manufacturing, installation, replacing that a lot of convenience are provided again.The utlity model has simple in structurely, ability is big, in light weight, make and safeguard advantages such as easy and convenient, and the occasion that is adapted to the slow-speed of revolution, big torque is used, and receives praises from customers.
