The end stage of the speed reducer outputs a hollow shaft which is sheathed on the drive shaft of the host machine directly and is locked by a locking disc, one end of a torque rod is connected with a flange disc of the speed reducer, the other end of the torque rod is connected with one end of a support pole in rotatable mode, and the other end of the support pole is welded with the frame of the host machine together. The present invention has the advantages that the drive device does not need a foundation, the support area of the foundation is reduced, installation cost and requirements for precision adjustment are reduced, and the vibration influence of the drive device on the host machine is lightened. Additional force is reduced, the transmission efficiency is improved, and the transverse size of a material feeding machine can be reduced maximally by the drive device.
Description
Technical field
The present invention relates to a kind of drive unit of apron feeder.
Background technique
The ordinary circumstance drive unit is made up of motor, coupling, retarder, frame etc., and connects with the basis by frame.Situation all was that sprocket wheel is connected with coupling with reducer output shaft in the past.If adopt coupling (comprising rigidity, elasticity),, all can produce the additional load of axle and bearing and increased axial dimension though can allow axial displacement, radial displacement, axis angular deflection and comprehensive skew etc.
Summary of the invention
The purpose of this invention is to provide a kind of driver with single point supporting, be used for apron feeder, have the effect of vibration damping, reduction additional force, improved transmission efficiency.
Driver with single point supporting, comprise motor, frame, orthogonal and planetary reducer, it is characterized in that driving equipment suspension is on the live axle of main frame: motor is connected with the orthogonal planetary reducer by coupling, the final stage output hollow shaft of retarder directly is enclosed within on the live axle of main frame, lock by locking plate, one end of torque tube connects with the flange plate of reducer shell, and the other end of torque tube connects rotationally with bearing post one end, and the other end and the frame of bearing post are welded together.
Advantage of the present invention is:
1. adopt the single point supporting form, drive unit does not need the basis, directly is suspended on the live axle of main frame, has not only reduced cost but also can guarantee installation precision.The reducer final stage geared sleeve on live axle, has just been solved the problem of multi-point support decentraction between live axle and the reducer final stage axle, the required precision of adjusting has been installed thereby reduced.
2. reduce the dimension precision requirement that the basis is installed, dwindled the area of foundation support.Because live axle and final stage gear employing hollow shaft are installed, it installs the bearing support basis of live axle and the height error on single point supporting basis does not influence transmission accuracy, thereby has reduced the dimension precision requirement to basic relative height.The foundation area that the foundation area of single point supporting is laid base than non-some supporting is much smaller.
3. damping effect is arranged: drive unit has not had the basis, because the variation of chain tensile force of belt, and the vibration of making drive unit that alignment error causes can not be delivered on the basis, thereby has alleviated the influence of vibration to main frame.
4. reduce additional force, improved transmission efficiency.Since removed live axle and and retarder between coupling, then the additional force by caused live axle and final stage gear shaft in manufacturing, alignment error and the work obviously reduces; Improved gear-driven efficiency simultaneously.Retarder adopts the hard flank of tooth combined type of orthogonal planet, adopts oil sump lubricated, and high speed shaft is equipped with non-return device, guarantees the wraparound self-locking.Output shaft end adopts locking plate to connect, and can guarantee concentricity preferably.This drive unit can reduce the transverse dimension of distributor to greatest extent.
