The technical solution of the utility model is:
A kind of lathe feed gear, installs supporting seat I and supporting seat II on saddle, the two ends of leading screw are arranged at respectively in supporting seat I and supporting seat II, and leading screw is installed on slide plate by feed screw nut.
Described lathe feed gear, mounted motor in supporting seat I, the output of motor is connected by shaft coupling with one end of leading screw, and the other end of leading screw is installed the bearing unit with supporting seat II secure fit.
Described lathe feed gear, the bearing unit of the leading screw other end is fixed by screw and supporting seat II, and bearing unit radially and between the dead eye of supporting seat II has difference in size.
Described lathe feed gear, bearing unit is located by half the circumference of the sleeve where it joins the shoulder on leading screw, and locks by round nut.
Described lathe feed gear, leading screw supports by deep groove ball bearing between one end of motor and supporting seat I.
Described lathe feed gear, deep groove ball bearing is fixing on leading screw by end ring.
Described lathe feed gear, coordinates between deep groove ball bearing outer ring and the hole of supporting seat I for matched in clearance.
Described lathe feed gear, arranges round nut at bearing unit outside on leading screw.
, there is difference in size between the installing hole of nut seat on feed screw nut and slide plate in described lathe feed gear, feed screw nut is located and is fixed on the nut seat of slide plate by end face of flange.
Principle of the present utility model is:
Motor side leading screw is supported for a bit (hinged point), and feed screw nut is for a bit, by the guide effect of guide rail, and above-mentioned 2 definite lead screw position, after leading screw tail end bearing is fixing, 3 are point-blank, ensure not suppress strength.
Advantage of the present utility model and beneficial effect are:
1, the utility model motor is fixed on saddle by supporting seat, and motor shaft is connected by shaft coupling with leading screw.Leading screw two ends are supported with bearing (bearing unit), and feed screw nut is fixed on slide plate, and motor, motor supporting base, leading screw, leading screw end support seat form the agent structure of infeed mean.This structure is carried out alignment leading screw by the guide effect of guide rail, has avoided repeatedly beating the complicated processes of position relationship between table, match grinding adjusting pad adjusting screw and guide rail, has improved efficiency of assembling.
2, the utility model motor side leading screw adopts deep groove ball bearing to support, and between bearing outer ring and supporting seat hole, is matched in clearance, avoids the generation of additional force when the characteristic of deep-groove ball is adjusted leading screw.
In a word, adopt after the utility model structure, owing to having difference in size between tail end bearing unit and bracing frame hole, have larger gap, tail end is free state; Motor side is deep groove ball bearing, and leading screw assembles under nature, by stretching leading screw rear rigid bearing unit, has avoided leading screw to suppress strength by the guide effect of guide rail.And the link that has reduced match grinding and repeatedly played table, has improved efficiency of assembling, reduce the processing cost of supporting seat.
