Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
As shown in the figure, a kind of vertical grinder main axis transmission system that the present invention discloses, comprises motor 20, electrical machine belt pulley 21, V belt 22, big belt pulley 23, flat key 24, and bearing automatic adjusting mechanism, and bearing automatic adjusting mechanism also comprises grinding wheel spindle 1; Motor 20 and electrical machine belt pulley 21 are connected, and electrical machine belt pulley 21 is connected by V belt 22 and big belt pulley 23, and big belt pulley 23 is connected by flat key 24 and grinding wheel spindle 1.
Bearing automatic adjusting mechanism, comprises grinding wheel spindle 1, main shaft sleeve 2, and grinding wheel spindle 1 is arranged in main shaft sleeve 2, and the tail end of grinding wheel spindle 1 is disposed with round nut A11, floor clip A12, taper roll bearing 3, butterfly spring A13, back-up ring 14; Grinding wheel spindle 1 front end is disposed with round nut B15, floor clip B16, butterfly spring B17, tensioning tapered sleeve 6, angular contact bearing 4, wherein tensioning tapered sleeve 6 is also provided with Biserial cylindrical roller bearing 5.
Wherein round nut A11 is fixedly installed on grinding wheel spindle 1, the inner ring of taper roll bearing 3 is linked on grinding wheel spindle 1, the outer ring of taper roll bearing 3 is then close to the inwall of main shaft sleeve 2, and floor clip A12 is between round nut A11 and the inner ring of taper roll bearing 3; Back-up ring 14 is fixed on main shaft sleeve 2, and does not contact with grinding wheel spindle 1, and butterfly spring A13 is then between back-up ring 14 and taper roll bearing 3.
Round nut B15 is fixedly installed on grinding wheel spindle 1, be floor clip B16 between round nut B15 and butterfly spring B17, the opposite side of butterfly spring B17 is tensioning tapered sleeve 6, tensioning tapered sleeve 6 is between the inner ring and grinding wheel spindle 1 of Biserial cylindrical roller bearing 5, and the outer ring of Biserial cylindrical roller bearing 5 is then close on the inwall of main shaft sleeve 2; The inner ring of angular contact bearing 4 is linked on grinding wheel spindle 1 that outer ring is close on the inwall of main shaft sleeve 2, is in grinding wheel spindle 1 foremost.
Described transmission system also comprises motor cabinet 30, motor seat board 25, bolt 27; Motor cabinet 30 and motor seat board 25 are arranged on outside electrical machine belt pulley 21, shield to electrical machine belt pulley; Described motor cabinet 30 is provided with two rectangular-shaped projections 28, described motor seat board 25 offers four chutes 26, projection 28 is corresponding with the position of chute 26, and bolt 27 links together through chute 26 and projection 28; Set screw 29 in projection 28 upper end is by bolt stake 31, and can promote projection 28, drive motor seat 30 moves up and down, thus electrical machine belt pulley 21 is moved up and down, thus plays the effect of adjusting triangle belt 22 degree of tightness.After adjustment, the nuts and bolt 27 on fastening screw deadman 31.
Specific works principle of the present invention is:
Motor 20 rotates through axle drive motor belt wheel 21 and rotates, and electrical machine belt pulley 21 drives big belt pulley 23 to rotate by V belt 22, and big belt pulley 23 drives grinding wheel spindle 1 to rotate by flat key 24, thus drives emery wheel to rotate.
At grinding wheel spindle 1 tail end, the butterfly spring A13 under compressive state is provided with between back-up ring 14 and taper roll bearing 3, and back-up ring 14 is fixedly installed on main shaft sleeve 2, so butterfly spring A13 certainly will form a thrust to taper roll bearing 3, and the support force of the round nut A11 that the another side of taper roll bearing 3 is fixedly installed and floor clip A12, so when taper roll bearing 3 and angular contact bearing 4 have trace wearing and tearing, under the thrust of butterfly spring A13, taper roll bearing 3 can recover the magnitude of interference; And round nut A11 is fixed on grinding wheel spindle 1, so when taper roll bearing 3 is subject to the thrust of butterfly spring A13, round nut A11 is also subject to a thrust, this thrust can drive grinding wheel spindle 1 to do corresponding motion, thus make to be fastened on the angular contact bearing 4 on grinding wheel spindle 1 and move to the direction of Biserial cylindrical roller bearing 5, so the magnitude of interference of angular contact bearing 4 also can be adjusted under the effect of butterfly spring A13.
In like manner, in grinding wheel spindle 1 front end, butterfly spring B17 is under the support of round nut B15 and floor clip B16, a thrust is had to tensioning tapered sleeve 6, and the contact surface of tensioning tapered sleeve 6 and Biserial cylindrical roller bearing 5 tilts, tensioning tapered sleeve 6 can promote Biserial cylindrical roller bearing 5, and Biserial cylindrical roller bearing 5 can obtain the support of angular contact bearing 4, so the magnitude of interference of Biserial cylindrical roller bearing 5 can be adjusted.
By said method, achieve the magnitude of interference with butterfly spring self-aligning bearing because of bearing wear; And the design of grinding wheel spindle 1 three bearings, achieve grinding wheel spindle 1 three fulcrum support structure, improve the performance such as rigidity and critical speed of grinding wheel spindle 1.
Because belt pulley 23 controls its radial force by two common ball bearings, so grinding wheel spindle 1 is not by belt pull, the effect of grinding wheel spindle 1 torque suspension, improves the rotation precision of grinding wheel spindle 1.
Above are only specific embodiments of the invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
