In order to solve the above-mentioned technical problem, the utility model purpose is to provide a kind of mark suitable for dynamic pressure centerless grinder
Fiducial axis watt Guiding wheel structure, can overcome the deficiencies in the prior art, improve guide wheel shaft transmission accuracy.
The utility model is achieved by following technical solution：A kind of standard axle suitable for dynamic pressure centerless grinder
Watt Guiding wheel structure, including servomotor, worm type of reduction gearing, guide wheel head body, guide wheel main shaft, guide wheel, rear end bearing shell, middle-end axle
Watt and front end bearing shell, it is characterised in that：The input shaft of worm type of reduction gearing is connected with servomotor, worm type of reduction gearing
Output shaft be connected with guide wheel main shaft, rear end bearing shell, middle-end bearing shell and front end bearing shell are arranged on guide wheel head in vivo, internal diameter and guide wheel
Main shaft major diameter fit, end-journal is equipped with rolling bearing after described guide wheel main shaft, and guide wheel is housed at taper, and front end is provided with leakproof spiral shell
Lid.
A kind of described standard bearing Guiding wheel structure suitable for dynamic pressure centerless grinder, it is characterised in that：Described rear end
Bearing shell and middle-end bearing shell are size identical standard bearing, and middle-end bearing shell one end has bearing lock nut to lock, and the other end has axle
Hold fixing nut to fix, shell is provided with oil-piping.
Beneficial effect：
The utility model improve after cramped construction, using standard bearing, the exchange species that reduces different bearing shells is more, cost compared with
Problem high, using standard bearing, the rigidity of guide wheel shaft is lifted, identical bearing shell, cooperation optical axis, work in-process axiality,
Runout error can preferably ensure, while increasing the transmission accuracy and service life of whole guide wheel.
