Technical field

The utility model belongs to upright ring type magnetic separator, especially relates to a kind of regulating device of gear backlash of upright ring type magnetic separator.

Background technique

In the magnetic separator of upright ring type, need change with the gearwheel band rotates to guarantee that machine moves continuously, but because the rotating speed of change is slower, working time of a specified duration the flank of tooth must wear and tear, the back lash is strengthened, and makes change produce the stepping phenomenon in rotation process, and cause complete machine to shake, have a strong impact on efficiency of magnetic separation, simultaneously, increased amount of maintenance and cost of production.

Summary of the invention

The purpose of this utility model provides a kind of upright ring type magnetic separator change gear backlash regulating device, can adjust the back lash between the change driving gear as required, guarantee the normal operation of upright ring type magnetic separator, increase the service life, reduce amount of maintenance, reduce production costs.

The purpose of this utility model is achieved like this: a kind of upright ring type magnetic separator change gear backlash regulating device, comprise speed reducer, gearwheel and small gear, small gear is installed on the speed reducer output shaft with key, small gear is meshed with gearwheel, the power of speed reducer output is passed to gearwheel by small gear, gearwheel drives the change rotation of upright ring type magnetic separator again, it is characterized in that: the left side that is positioned at small gear on the left end section of speed reducer output shaft is slidingly installed and transfers the crack gear, this small gear and accent crack gear mesh with gearwheel simultaneously, offer long waist shaped through hole symmetrically at the front upper part of transferring crack gear left surface and rear and low part with the radial center distance, in each long waist shaped through hole, install clamping bolt I, and corresponding being screwed in the screw of offering on the small gear, transfer the crack gear to be fixed on the small gear this, this transfers the crack gear to do radially to rotate around speed reducer output shaft as required, (will unscrew the clamping bolt I in each long waist shaped through hole this moment) is to adjust the back lash of transferring between crack gear and the gearwheel; Offer screw symmetrically and fixedly mount positioning block respectively superior posterior of transferring crack gear left surface and preceding bottom with clamping bolt III, this positioning block is section ringwise, the middle part of each positioning block and transferring on the gear of crack correspondence offer cone shape hole and in cone shape hole the corresponding taper pin of installing, each positioning block is positioned to transfer on the gear of crack; In addition, on the center line of the left side of speed reducer output shaft, offer vertical rectangle groove, on the vertical center line of the left side of speed reducer output shaft, offer screw up and down symmetrically and with the slide block of the rectangular rectangular cross-section of the vertical fixed installation of clamping bolt II, this slide block is inlaid in the rectangle groove again simultaneously, and on the upper and lower end section of this slide block, offer sagittal screw respectively symmetrically, and spinning adjustment bolt is also respectively with locking nut locking opposite to each other in the screw about this, and each overhanging end correspondence of adjusting bolt is resisted against on the end face of each positioning block.

When the back lash of crack gear and gearwheel is transferred in the needs adjustment, adjust locking nut on bolt as long as unclamp clamping bolt I in each long waist shaped through hole and each earlier, corresponding then adjustment bolt pushing tow positioning block of twisting on the slide block, make the adjustment of transferring the crack gear to relatively rotate just can to realize, guarantee to stand ring type magnetic separator proper functioning with the back lash of gearwheel.

The upright ring type magnetic separator change gear backlash regulating device that the utility model proposed, rational in infrastructure, use reliably, reduce the transmission noise, prevent change shake and stepping effectively, guarantee the normal operation of upright ring type magnetic separator.

Now in conjunction with the accompanying drawings and embodiments the upright ring type magnetic separator change gear backlash regulating device that the utility model proposed is described further.
