It is equipped with grinding head body, grinding head body is also fixedly installed with sleeve at the position between drive end bearing bracket and tail cover, and grinding head body is located at
Hydraulic oil oil inlet is offered at the medium position of top surface, grinding head body is located at bottom surface and is also provided at the position of tail cover
Hydraulic oil oil return opening, hydraulic oil oil inlet and hydraulic oil oil return opening extend inwardly to sleeve outer surface vertically, sleeve top surface and
Bottom surface is also provided with several oil leak holes.
Preferably, side of the main shaft body close to drive end bearing bracket far from flange grinding wheel also forms cross section in lateral etc.
Waist trapezoidal chimb is fixedly installed with copper bearing bore on the outside of chimb.
Preferably, side of the main shaft body close to tail cover far from motor housing is also rotatably provided with movable cone
Set.
Preferably, grinding head body medial surface, which is located at, also forms Sheng oil pocket at the position of sleeve bottom surface, sleeve is located at
Intermediate oil leak hole is also formed at the medium position of bottom surface.
Preferably, the diameter of intermediate oil leak hole is greater than the diameter of oil leak hole.Can thus it make when draining hole plug,
Draining can also be carried out by intermediate oil leak hole, and contains oil pocket by increasing, so that entire oil return process is more smooth, avoided
Occur due to the excessive caused difficulty of refueling of the pressure difference of hydraulic oil oil inlet and hydraulic oil oil outlet.
The utility model has the beneficial effects that:
The present oil inlet of hydraulic oil oil inlet is offered in the utility model grinding head body to proceed directly on sleeve, can effectively be prevented
Phenomenon generation increase grinding head body bottom Sheng oil pocket makes oil return more smooth here, can reduce input pressure in this way.
