Abstract
nullThe utility model discloses a kind of guide pulley of centerless grinder main shaft direct drive mechanism，Including guide wheel axle bed，Described guide wheel axle bed front end is provided with guide wheel，Described guide wheel shaft base rear end is disposed with reductor and fixes seat、Concentric locating circle、Guide wheel main shaft、Shaft coupling、Reductor and motor，Described reductor is connected with the guide wheel main shaft being arranged on reductor and fixing base rear end by shaft coupling，It is additionally provided with concentric locating circle between described guide wheel main shaft and described reductor centring ring，The motor of described guide wheel axle bed rearmost end is connected with reductor，Described motor is servomotor，By using servomotor directly to drive guide wheel main shaft through shaft coupling after reductor slows down and increases torsion，Can be avoided the tensile force impact on main shaft，Reduce and start frictional force and the abrasion of bearing shell，Improve transmission performance，Higher running accuracy can be obtained simultaneously，And run stability is good，The quality of improving product and production efficiency.
Description
Technical field
This utility model relates to mechanical equipment technical field, particularly relates to a kind of guide pulley of centerless grinder main shaft and directly drives machine
Structure.
Background technology
Grinding machine is to utilize grinding tool that surface of the work carries out the lathe of grinding, and centerless grinder to be one need not use
The axle center of workpiece and implement a class grinding machine of grinding, mainly by emery wheel, guide wheel and supporting plate are constituted；On centreless grinding machine external,
Workpiece need not top centering and supporting, and be placed between emery wheel and guide wheel, supporting plate and guide wheel support, emery wheel high-speed rotary rotates into
Row grinding, guide wheel, with slower speed rotating Vortex, drives workpiece to rotate and makees feed motion.Guide wheel main shaft is the groundwork of grinding machine
Parts, the kind of drive of guide wheel main shaft is also one of factor affecting grinding accuracy, the kind of drive of existing guide wheel main shaft be by
Drive motor to pass to one by belt and fix axle, fix axle and pass to guide wheel main shaft by single-chain, for secondary transmission, due to
Belt or chain all can have the existence of tensile force, and therefore main shaft is affected by tensile force for a long time, are easily caused startup frictional force big,
Bearing shell is easy to wear, affects transmission performance, produces bigger noise simultaneously.
Utility model content
For deficiency of the prior art, this utility model provides a kind of guide pulley of centerless grinder main shaft and directly drives machine
Structure, by using servomotor directly to drive guide wheel main shaft, this structure energy through shaft coupling after reductor slows down and increases torsion
Obtain higher running accuracy, and run stability is good, reduce abrasion and noise, the quality of improving product and production efficiency.
To achieve these goals, this utility model have employed following technical scheme and is addressed: a kind of centerless grinder
Guide wheel main shaft direct drive mechanism, including guide wheel axle bed, described guide wheel axle bed front end is provided with guide wheel, described guide wheel shaft base rear end
Being disposed with reductor and fix seat, concentric locating circle, guide wheel main shaft, shaft coupling, reductor and motor, described reductor passes through
Shaft coupling is connected with the guide wheel main shaft being arranged on reductor and fixing base rear end, described guide wheel main shaft and described reductor centring ring it
Between be additionally provided with concentric locating circle, the motor of described guide wheel axle bed rearmost end is connected with reductor.
In such scheme, it is preferred that described motor is servomotor.
Compared with prior art, this utility model has the advantages that in this utility model, by using servo electricity
Machine directly drives guide wheel main shaft through shaft coupling after reductor slows down and increases torsion, can be avoided the tensile force shadow to main shaft
Ring, reduce and start frictional force and the abrasion of bearing shell, improve transmission performance, higher running accuracy can be obtained simultaneously, and operating is steady
Qualitative good, the quality of improving product and production efficiency.
Accompanying drawing explanation
Fig. 1 this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings with detailed description of the invention, this utility model is further described.
Seeing Fig. 1, a kind of guide pulley of centerless grinder main shaft direct drive mechanism, including guide wheel axle bed 2, described guide wheel axle bed 2
Front end is provided with guide wheel 1, and described guide wheel axle bed 2 rear end is disposed with reductor and fixes seat 3, concentric locating circle 4, guide wheel main shaft
5, shaft coupling 6, reductor 7 and motor 8, described reductor 7 fixes leading of seat 3 rear end by shaft coupling 6 with being arranged on reductor
Wheel main shaft 5 connects, and described guide wheel main shaft 5 and described reductor are fixed and be additionally provided with concentric locating circle 4 between seat 3, described guide wheel
The motor 8 that axle bed 2 rearmost end is arranged is connected with reductor 7, and described motor 8 is set to servomotor.
The direct drive mechanism of guide wheel main shaft 5 is to use servomotor 8 to slow down through reductor 7 to increase after torsion, through shaft coupling
Device 6 directly drives the motion of guide wheel main shaft 5, it is to avoid the tensile force impact on guide wheel main shaft 5, reduces and starts frictional force and bearing shell
Abrasion, improve transmission performance, simultaneously can obtain higher running accuracy, and run stability is good, the quality of improving product with
Production efficiency.
Protection domain of the present utility model includes but not limited to embodiment of above, and protection domain of the present utility model is with power
Profit claim is as the criterion, and replacement that any those skilled in the art making this technology is readily apparent that, deforms, improves and each fall within
Protection domain of the present utility model.
