Abstract
A roller grinding eccentric locking collar feeding mechanism supported by a tapered roller bearing is composed of bearing bases, an eccentric locking collar, tapered roller bearings, a swing rod, a ball screw, a locating ring and spacers. The roller grinding eccentric locking collar feeding mechanism supported by the tapered roller bearing is characterized in that two sets of double-row tapered roller bearings C (11) and tapered roller bearings D (12) which are arranged in a face-to-face mode are installed on the bearing base (6) at a grinding wheel (15) end and on the bearing base (6) at a belt pulley (1) end. A double-row tapered roller bearing A (4), a tapered roller bearing B (7) and the eccentric locking collar (8) form a double-row four-position support structure. Gaps, paired up with each other, of the tapered roller bearings are adjusted through a match grinding spacer A (3) and a spacer B (13). Gaps of a tapered roller bearing A (4), a tapered roller bearing B (7), a tapered roller bearing C (11) and a tapered roller bearing D (12) are adjusted to be zero, and the front ends and the back ends of the tapered roller bearing A (4), the tapered roller bearing B (7), the tapered roller bearing C (11) and the tapered roller bearing D (12) are paired up with each other.
Description
Technical field
The utility model relates to the support of revolving body, particularly a kind of roll mill eccentric bushing feed mechanism of taper roll bearing support.
Background technology:Towards high accuracy and high reliability future development, numerous traditional function parts all need to continue to optimize and improve along with Digit Control Machine Tool.Prick in the steel industry in heat, the grinding wheel spindle of roller grinding machine adopts the drives structure of eccentric bushing usually, and this structure has the effect that promotes machine tool feed resolution ratio and feed accuracy, is therefore the lathe core component.But the generally outer of these parts supported by hydrostatic bearing, therefore can cause the not enough shortcoming of rigidity, and this is also one of reason that causes Roller Machining surface generation spiral lamination and shake line.Therefore, be necessary to change the supporting form of eccentric bushing, make it have larger rigidity.Double-row conical has the function that the gap is adjusted, because roll mill eccentric bushing is a low speed and rotating mechanism by a small margin, therefore the bearing clearance can be adjusted into zero, thereby when keeping roll mill eccentric bushing advantage, farthest increase its rigidity, to satisfy the high-precision grinding of roll mill.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure and have the supporting mechanism of the roll mill eccentric bushing of larger rigidity, and this mechanism can be good at solving traditional static pressure and supports rigidity deficiency and the complex structure and other problems of bringing.
Formation of the present utility model: the roll mill eccentric bushing feed mechanism that a kind of taper roll bearing supports, formed by bearing block, eccentric bushing, taper roll bearing, fork, ball-screw, locating ring and pad, it is characterized in that: be separately installed with the aspectant double-row conical bearing C of cover and a taper roll bearing D on the bearing block of emery wheel end and pulley end, double-row conical bearing A and taper roll bearing B consist of four supporting constructions of biserial to eccentric bushing.
The gap of the taper roll bearing of pairing is adjusted by match grinding pad A, pad B mutually.
The gap of the taper roll bearing A that front and back ends matches mutually, taper roll bearing B, taper roll bearing C, taper roll bearing D all is adjusted into zero.
Compared with prior art, the utlity model has following features: for the structure that common employing hydrostatic bearing supports, taper roll bearing supports has characteristics simple in structure.In addition, the gap of taper roll bearing adjusts to zero by the method for match grinding pad, therefore has the rigidity larger than other structure.
